TRANSMISSION

The transmission of the car is a combination of aggregates and mechanisms intended for transmitting torque from the engine to drive wheels and changes in its size and direction. Transmission (Fig. 1.1) Car KAMAZ mechanical and consists of clutch, gearbox, dispensing box, cardan Transmission, main gears, differentials, semi-axes

Fig. 1.1. Layout transmission scheme:

1-clutch; 2-box gear; 3 transfer box; 4-cardan transfer; five- main gear and differential; 6-semi-axis

Clutch clutch is designed for: ü disconnecting the engine from transmission at shift shifting, cutting braking; ü smooth connection of the engine with a transmission when starting with space; ü Engine prevention and transmission from overload; ü Torque transmission from the gear engine. By type of coupling dry, two-disc, constantly on, with peripheral location of pressure springs. It is located in the engine crankcase, and consists of a clutch and control mechanism.

1.1. Clutch mechanism

It consists (Fig. 1.2) from the leading parts, slave parts, pressure device, shutdown mechanism. The principle of clutch operation is based on the use of friction forces arising between discs. Leading clutch discs are perceived from the flywheel torque of the engine, and the driven discs transmit this moment of the engine primary gearbox shaft. The pressure device (12 pressure springs) provides a dense pressing of the leading and driven clutch parts to create the required torque. Torque from the leading parts is transmitted to the led by the friction forces.

Clutch mechanism: 1- slave disk; 2nd drive; 3 installation sleeve; 4- pressure disk; 5-plug of the exhaust lever; 6-delayed lever: 7-spring of a stubborn ring; 8-hose clutch lubrication; 9-loop springs; 10-release bearing; 11-exhaust spring; 12-coupling clutch off; 13 - fork of clutch shutdown; 14- Stubborn ring; 15 - shaft fork; 16- push spring; 17- casing; 18-heat insulating washer; 19- bolt of fastening of the casing; 20- Coupling Carter; 21-flywheel; 22 friction bookmark; 23 - primary shaft; 24-disk of steep oscillations; 25- springs of steep oscillations; 26-ring driven disk; 27-mechanism of automatic adjustment of the position of the average drive disk to lead details include the average drive disc, push disk, clutch casing.

The average drive disk (Fig. 1.3, a) is cast from cast iron and installed in the gakhovka grooves on four spikes, evenly arranged around the circle of the disk. To ensure the adhesion ventilation, the best heat removal and weight reduction in the body of the disk are windows separated by internal ribs. Spikes placed a lever mechanism that mechanically adjusts the position of the middle disk when the clutch is turned off in order to ensure the cleanliness of the shutdown. The pressure disk (Fig. 1.3, b) is cast from gray cast iron, like the average drive disc, installed in the woven grooves on four spikes. On the one hand, the disk has a grinded surface, on the other - 12 bobbs to install push springs.

Fig. 1.3. Clutch discs: a - average drive disc; b - pressure disk; in the slave disk with the damper assembly: 1-hub; 2-rivet; 3-rope damper; 4-slave disk; 5 friction lining; 6- Spring of the damper. Each thorn from the side of the casing has a tide in which the discreet grooves and two holes are brewed to set the axis of the clutch off lever. The adhesion casing steel, stamped, is installed on the flywheel crankcase on two installation sleeves and is attached 12 bolts. In the casing there are 12 recesses for installing springs and holes for the installation of levers.

TO slave details There are two slave disks with a damper, the slave clutch shaft (it is the primary shaft of the gearbox). The slave disk (Fig. 1.3, B) consists of a disk with friction linings, a disk hubs, a damper (spinning oscillation damper). The slave disk is made of steel. In the center of the disk there is a hole for installing the hub. The disk has eight windows for the damper springs. According to the periphery of the disk on both sides, the friction pads made from the asbestos composition are riveted on both sides. The hub has internal slots, which are installed on the slots of the primary shaft of the gearbox. The hub also made eight windows for the damper springs. The damper serves to quench the vibrations that occur in the engine and transmission. Due to the uneven operation of the engine and the elasticity of the crankshaft, constant twisting and the spinning of the shaft occurs, i.e. There are own twisting oscillations. In the transmission there are shafts of the gearbox, transfer box, cardan transmission, semi-axes.

With a sharp turn on the clutch, braking the car without turning off the clutch, during the wheel by an obstacle in the transmissions shafts there are forced oscillations. With the uneven operation of the engine, the automotive oscillations from the engine can be transmitted to the transmission. This is especially dangerous when the frequency of its own angular oscillations of the transmission coincides with the frequency of the vibrations. In this case, there is a resonance and the load on the transmission details increases sharply, which can lead to the breakdown of them. Forced twist fluctuations in the transmission, in turn, can be transmitted to the engine, which dramatically increases the load on its parts. Therefore, damasters are installed for protection against resonant twisting vibrations of the shafts in the slave clutch discs (vibrations of vibrations). The damper has elastic and friction elements.

The elastic element serves to change the frequency of the vibrations of the shafts and prevent the phenomenon of the resonance, i.e. The coincidence of the frequencies of their own angular oscillations and tweeted oscillations, and consists of eight cylindrical springs. The friction element reduces the amplitudes of forced oscillations, transforming the oscillation energy to heat, and consists of two rings, two disks, two friction rings. The hub flange on both sides is the damper and clutch discs. Friction rings on both sides are the led disc. Friction rings and dampers also have eight windows, windows for springs coincide with windows in the drive disk and the flange of the hub. Eight cylindrical springs are installed in the windows.

Thus, there is no tough connection between the slave disk and its hub - they are connected only after eight springs. Dempfection discs are made in the form of disk springs and are constantly pressed against the friction rings. In the occurrence of steep oscillations of the hub, the slave disk is rotated relative to the disc itself; The springs of the damper, compressing, change the frequency of oscillations, ensuring the mismatch of the frequencies of its own oscillations of transmission and forced steep oscillations, i.e. prevent the resonance phenomenon. When turning the hub, the dams of the damper slide along the friction rings, and due to the friction, the energy of oscillations turns into heat.

Pressing device (See Fig. 1.2) consists of twelve springs. The springs are based on the gluits of the pressure disk through the washers from the thermal insulation material. The total force of springs is 10500 ... 12200n (1050 ... 1220 kgf).

Shutdown mechanism Consists of four dedicated levers, a stubborn ring, clutch off coupling with released Bearing, plugs off the clutch with a shaft, two detentious springs. Four hand levers are installed on a pressure disk and connect with a casing with a fork. Exhaust levers are connected to the pressure disk and finger forks. Fingers are installed in disk and forks on needle bearings. On the axis of the lever in the fork, the spring of the thrust ring is installed, which rests on with one mustache in the casing, and the stubborn ring is constantly pressed through the loop to the squeezing levers. The stubborn ring protects the exhaust levers from wear. To turn off the clutch on the gearbox cover, the clutch clutch clutch is installed with the bearing assembly. The coupling under the action of the springs is constantly pressed with crops pressed into it to the laps of the clutch shutting. For lubrication clutch and bearing installed lubricant supply hose and oil on the clutch crankcase. The adhesion turning plug is mounted on the drive shaft, which, in turn, is installed on the bushings in the clutch crankcase. Fork tree lever is installed on the outer end of the shaft.

1.2. Clutch control mechanism Drive remote, hydraulic, with a pneumotor, is designed to turn off the clutch. The container of its hydraulic system is 0.38 liters. Applied liquid GTH-22M or "Neva", "Tom". It consists (Fig. 1.4) from clutch pedals With the exhaust spring, the main cylinder, the pneumohydraulic amplifier, the lever of the shaft of the adhesion of the clutch with the exhaust spring, pusher, pipelines.

When you press the pedal when the clutch is turned off, the driver from foot drive through the lever and the rod is transmitted to the main cylinder, from where the pressure fluid on the pipeline enters the housing of the tracking device, which makes the compressed air passaged by the aircraft reduction valve From a balloon. Sound from the main cylinder, the pressure fluid enters the hydraulic cylinder of the amplifier. The total air pressure force in the air cylinder and the pressure of the fluid in the hydraulic cylinder is transmitted to the rod of the pneumulator.

The rod moves the clutch shutting shaft shaft lever, which, turning, turns off the clutch. Clutch pedal Installed on the axis of the bracket. It transmits a force on the piston piston of the main cylinder using the lever and the eccentric finger. Chief cylinder (Fig. 1.5) is installed on the clutch pedal bracket.

Cylinder: 1 piston 1 pusher; 2-housing; 3-piston; 4-housing of the tank; 5-clearance of the free move of the main cylinder; A- The clearance of the free move of the main cylinder consists of a cylinder body, a protective cover, rod, piston, an end sealing cuff, springs, cylinder tubes, a tank housing.

In the housing of the main cylinder, two cavities are formed separated by partition. The upper cavity together with the tank is designed to refuel the hydraulic material of the working fluid and the storage of the desired stock of the working fluid. The lower cavity performs the function of the working cavity of the main cylinder, in which the piston is installed with the cuff and spring. Pneumohydraulic clutch drive amplifier serves to create additional efforts to facilitate the clutch management. It is attached by two bolts to the clutch crankcase flange on the right side.

The amplifier (Fig. 1.6) consists of the front 35 and the rear 44 housings, the clutch shutdown piston 43 with a pusher 3, piston piston 31, the tracking device.

It cropped the hole (at the top) and drilling (below).

Drilling is intended for installation of a pneumatic piston. The upper stepped hole is designed to install the inlet valve with the seat seat seat. The valve cavity in the upper hole and the internal space of the lower drilling canal are connected. In the case wall there is a traffic jam 33 to remove condensate. The front-end cylinder is a pneumatic piston 31 with a cuff and a return spring. The piston is pressed on the pusher, made as one with a hydraulic piston.

The pusher of the hydraulic piston has a spherical nut 1 and a lock nut 2. Efforts from the pneumatic and hydraulic working pistons are summed up and transmitted through the pusher and its spherical nut on the lever of the shaft of the clutch shutdown. In the back cast iron case 44, a hole (bottom) and drilling (at the top) are bored. The hole performs the role of the cylinder of the hydraulic piston of the clutch shutdown. From the front of the front case, the piston seal is installed and fixed. The top drilling is designed to set the housing of the piston of the tracking device. The working fluid from the main cylinder enters the cavity of the hydraulic piston through the hole and in the housing.

The compressed air into the upper cavity of the front body is supplied through the hole in the housing lid. The tracking device is designed to automatically change the air pressure in the power pneumatic cylinder for the piston in proportion to the enhancement pedal. It consists of a follow-up piston with a cuff 8, the housing of the tracking piston 10, aperture with an exhaust valve seat and a spring, outcomes and intake valves with a return spring. The housing is installed behind the piston with the cuff. Piston stroke is limited by a stubborn ring. The diaphragm is clamped between the housings; In it, with the help of the nuts, the saddle of the exhaust valve and the two springs of the diaphragm springs are fixed. The conical graduation and intake valves are assembled on a common rod. The valve spring presses the intake valve to the saddle fixed in the housing using air supply covers.

The channel b to supply compressed air into a pneumatic piston cylinder is connected to the cavity in front of the diaphragm by the calibrated hole. The air from the piston cylinder is available through the outlet valve, the inner cavity of the exhaust valve seat and the hole covered with the cover with the lid.

Chapter II. Work and maintenance of clutch

Clutch work Initial position.

The clutch drive pedal is in its original position, the main cylinder rod is in the upper position. The piston under the action of the spring is pressed to the casing partition. Between the stock and piston there is a gap, the cavity of the main cylinder is communicated to each other. In the pipeline connecting the main cylinder with the hydrauliculator, the pressure is missing. The pusher of the hydraulic piston of the hydraulicer under the action of the return spring of the shaft of the fork shaft is pressed to the hydraulic piston, which through another pusher holds the pneumatic piston in its original position. Pressure disk 4 (see Fig. 1.2) Clutch Under the action of pressure springs 16 presses slave discs to the average drive disc 2 and flywheel 21. Clutch shutdown clutch under the action of springs is allocated from a stop ring 14 by 3.2 ... 4mm, providing topics The most complete clutch is complete.

Torque, developed by the engine, from crankshaft Transmitted to the flywheel, the average leading and pressure disks and then due to friction on the slave disks. From the driven discs, the torque through the damper is transmitted to the hubs of slave disks and then on the primary shaft 23 of the gearbox.

Turning off the clutch. When the adhesive drive pedal is pressed, the pusher 1 of the main cylinder (see Fig. 1.5) closes the hole in the piston 3, preventing the flow of fluid from the lower cavity to the upper, and moves the piston, squeezing the spring. When moving the piston in the cylinder, the pressure is raised, which is transmitted by hoses and pipelines to the inlet of the pneumohydrocerer. The working fluid under pressure enters the cavity of the cylinder of the hydraulic piston of the amplifier (Fig. 1.6) and then on the channel in the rear case is supplied to the tracking piston 9. The tracking piston begins to move, squeezing the diaphragm spring and moving the exhaust valve seat. The saddle, moving, closes the exhaust valve, squeezing the valve spring, and opens the inlet valve. Compressed air enters the epipal space of a pneumatic piston 31.

The piston begins to move, squeezing the spring, and moves the hydraulic piston through the pusher, and it turns the shaft lever 15 through its pusher 3 (see Fig. 1.2), which, in turn, turns the shaft and associated clutch shutdown plug. Fork, the plug presses the clutch clutch clutches on the crackers, moves it, choosing a gap, until it stops in a stubborn ring of 14 levers. With a further movement of the coupling, the thrust ring presses to the delayed levers 6, turns them on the axes of the forks and presses the pressure disk 4 from the slave disk, while squeezing the pressure springs 16. The arms of the middle drive 27 under the action of its springs rotate and move the disk to the middle position.

The torque, developed by the engine, is not transmitted to the driven discs. Part of the compressed air through the calibrated holes in the front case is supplied to the cavity of the diaphragm. The tracking piston is under the action of two efforts towards each other. With a completely squeezed clutch pedal, the fluid pressure on the tracking piston is maximally, so the intake valve is fully open and the pneumatic piston under pressure of the compressed air takes the left position, providing a complete clutch shutdown.

Enable clutch. When the clutch pedal is released under the action of the exhaust spring returns to its original position, the piston of the main cylinder under the action of fluid pressure is also returned to initial position. The fluid pressure on the steering piston of the air cooler decreases, the tracking piston moves to the left position, the diaphragm under the action of the spring and the pressure of the compressed air begged by moving the exhaust valve saddle. The intake valve under the action of the spring sits on the saddle, stopping the supply of compressed air. The exhaust valve, with further movement of the saddle, it takes away from it and reports the epipment of the piston piston cylinder with an atmosphere.

The piston under the action of the spring moves into the right position. Hydraulic piston first under the action of pressure grip springs, and then under the action of the return spring, the clutch shutdling fork fork is starting. The clutch clutch clutch with the bearing ceases to affect the stubborn ring of the outflowing levers. In this case, the pressure disk under the action of pressure springs presses the slave discs to the flywheel and the average leading disk, the force of pressed increases gradually, due to the accuracy of the air cooler. The torque transmitted to the primary gearbox shaft is gradually increasing and reaches maximum value.

To complete the clutch shutdown, the driver must make an effort to pedal 150n (15kGS). In the absence of compressed air in the air pneumatic system, the clutch can be turned off due to pressure only in the hydraulic part of the amplifier. At the same time, to create the necessary pressure, the driver must increase the effort on the clutch pedal to 600n (60kgs).

On the tracking piston Amplifier has two efforts. One effort from fluid pressure to the piston, which seeks to move the piston and open the intake valve. Other - from the actions of the springs of the diaphragm and the pressure of compressed air to the diaphragm; It seeks to close the inlet valve. If the driver presses on the clutch pedal, not until it stops and stops it in an intermediate position, then when the pressure increases in the diaphragm cavity, when the force of compressed air and spring on the diaphragm will become greater than the fluid pressure on the tracking piston. In this case, the diaphragm will move to the left so much that the return spring will close the inlet valve. When moving the tracking piston, the fluid pressure increases and the effort on both sides of the tracking piston is balanced. In this case, both valves (intake and graduation) are closed and the tracking piston occupies an intermediate position.

With an increase in the pressure of the working fluid (i.e., with further movement of the clutch pedal), the intake valve will open and the new air portion will go into the pneumatic cylinder, which will ensure the movement of the piston and further turning off the clutch. The tracking effect of the pneumotor provides smooth inclusion of clutch.

Clutch maintenance

During the work of the clutch, the friction surfaces are made, interface control drive, loss of the tightness of the amplifier, which leads to a violation of the adjusting parameters. Lubricant is also consumed. The intensity of the listed processes depends mainly on the road conditions, the load values \u200b\u200bin the body on the hook, quantities vehicle On the roads, as well as from the practical skills of drivers. Therefore, during the operation of the car, the clutch maintenance is provided.

For maintenance: ü Check the tightness of the drive, the integrity of the exhaust springs of the clutch pedal and the clutch turnout shaft lever; ü Adjust the free stroke of the piston piston of the main cylinder of the drive and the free course of the clutch shutting plug shaft arm; ü Lubricate clutch shutting clutch bearings and clutch shutting down shaft; ü Check the fluid level in the tank of the main cylinder of the clutch drive, if necessary, add liquid; ü Tighten the fastening bolts; ü Change the fluid in the clutch hydraulic system (once a year in autumn). When operating, with the wear of the slave disks, it is necessary to adjust the clutch drive to ensure the free stroke of the clutch off.

Adjustment of the clutch drive It is to check and adjust the free move of the adhesion pedal, the free stroke of the clutch of the clutch and the complete move of the pusher pusher.

Free journey Turn off the clutch Check the movement manually lever fork shaft. At the same time, disconnect the spring from the lever. If the free course of the lever, measured on a radius of 90 mm, will be less than 3 mm, adjust its spherical nut of the pusher to a value of 3.7 ... 4.6 mm, which corresponds to the free move of the clutch off of the clutch 3.2 ... 4mm. The complete stroke of the pusher of the pneumatic carrier must be at least 25mm. Check the full course of the pusher of the pneumotor by pressing the clutch pedal until it stops. At a lower progress, the clutch is completely shutdown. In the event of an insufficient stroke of the pusher of the pneumotor, check the free move of the clutch pedal, the amount of fluid in the tank of the main cylinder of the adhesion drive, and if necessary, pump the hydraulic system of the clutch drive.

Free pedalscorresponding to the start of the main cylinder, should be 6 ... 15mm. It is necessary to measure it in the middle part of the coupling pedal. If the free move goes beyond the limits mentioned above, adjust the gap A (see Fig. 1.5) between the piston and the piston of the main cylinder piston with an eccentric finger 6 (see Fig. 1.4), which connects the upper hand of the pusher 7 with the lever of 5 pedals. Adjust the clearance when the exhaust spring 8 presses the clutch pedal to the top stop 4. Rotate the eccentric finger so that the movement of the pedal from the top stop until the piston is touched by the piston pusher at 6.15mm, then tighten and shrink the crown nut. The full course of the clutch pedal should be 185 ... 195mm.

Pumping hydraulic system To perform for the removal of air plugs resulting from a violation of the tightness of the hydraulic drive, in the following order: ü remove from the tank 4 (see Fig. 1.5) of the main cylinder Cork 5 and fill the tank working fluid to a level of at least 15 ... 20mm from the top The edges of the tank tank neck. Fill the system of working fluid by applying a mesh filter to avoid falling into the system of extraneous impurities; ü Remove from the bypass valve on the pneumauxylider Cap 12 (see Fig. 1.6) and put on the valve head hose for pumping hydraulic drive.

The free end of the hose is lowered into a glass vessel with a capacity of 0.5 liters, filled with the working fluid on 1/4 ... 1/3 of the height of the vessel; ü Unscrew to 1/2 ... 1 The turnover of the bypass valve and consistently press the clutch pedal until it stops into the stroke stop between the press 0.5 ... 1c until the release of air bubbles from the working fluid coming down the hose in the glass vessel; ü when pumping add liquid into the system, not allowing its decline in its level in the tank below 40 mm from the top edge of the tank neck to avoid entering the air; ü at the end of pumping while pressed until the clutch pedal stop stops to refuse the bypass valve, remove the hose from the valve head, put on the cap; ü After pumping the system to add fresh working fluid to the tank to a normal level (15 ... 20mm from the top edge of the tank neck). The quality of pumping is determined by the magnitude of the full run of the pusher of the pneumulator. To check the level of fluid during operation, open the cork of the tank of the tank. At the same time, the fluid level should be not lower than 15 ... 20mm from the top edge of the filling neck.

Chapter III. Possible malfunctions in the clutch and methods of their elimination

The following main faults can be in the clutch: drive violation of the drive adjustment, causing incomplete shutdown and non-plaid inclusion of clutch, slip discs; Wearing the friction linings of the slave disk, the bearing of the clutch clutch, the clutch drive working cylinder cylinder.

Slug clutch discs It occurs when weakening or breakage of the pressure springs, wear or blocking the surface of the flywheel and pressure disk, grinding the spicial linings of the slave disk. Faulty pressure springs and grinding friction linings are replaced with new ones. Friction surfaces of the flywheel and pressure disk are treated with grinding.

Incomplete clutch shutdown appears as a result of an increased free pedal stroke (with a mechanical drive) or a decrease in the stroke of the working cylinder (when hydraulic drive), as well as due to the deformation of the slave disk. The free pedal stroke is set when adjusting, and the defective slave disk is replaced with a new one.

Improved clutch inclusion It is determined by the wear of the slaves of the slave disk, difficult to move the hub of the slave disk, unimpressed by pressing the shutdown bearing, jamming the adhesion pedal on the axis. Difficult movement of the hub of the slave disk on the slots of the primary shaft of the gearbox occurs due to the presence of calas or burrs on the slots. The latter are cleaned and lubricated with a thin layer of graphite lubrication. The low-speed clutch shutdown bearing on the shutdown levers is eliminated by adjustment. When the clutch pedals are silent, the ends of the sleeves are cleaned with cauldron and burrs and lubricate them. When repair, worn clutch shutdown bearings are replaced with new ones. The slave and pressure discs, as well as pressure springs, depending on the state are restored or replaced. For execution repair work The clutch disassemble, applying devices, one of which is represented in Fig. 3.1.

Fig. 3.1. Demolition for disassembling and clutch assembly: 1- Support plate, 2 - clamping case, 3 - control ring, 4 - installation studs, 5 - base

Carter clutch And the block of cylinders during repair is not deleasing. They are labeled to prevent the device and ensure the coaxialness of the crankshaft of the engine and the drive shaft of the gearbox. If these parts are impersonal, then after assembly, the centering hole of the clutch crankcase is cleaned in the device. The main defects of the clutch cartridge are cracks, chips, breakdown or wear of the thread, wear of the holes and the supporting planes of the paw mounting to the frame. Carters are married if cracks capture more than half of the perimeter or pass more than one hole under the mounting bolts. Cracks on the clutch crankcase brew. Squares, breathtaking hole, prescribe or weld a sloping part of the part.

When breaking the threads to two threads, it is restored by a swing by the tag. If the thread has a breakdown of more than two threads or worn, it is restored by cutting the threads of increased repair size, writing or welding, followed by cutting the thread of the nominal size. Worn larger holes under the guide pin of the starter attachment, the engine mounting to the frame restore additional details - sleeve. After pressing the hole of the bushings is processed under the nominal size. The worn reference planes of the clutch crankcase mounting paws are treated on the milling machine to eliminate wear traces. With significant wear, welded washers.

Before welding, the surface of the paws are milling, and the holes are annoying for installation of the washers. Then the washers are welded to the adhesion of the clutch with a solid seam of electric arc welding. Complete the treatment of cenching ends of the paws flush with the main metal. Basic defects purpose and slave disks The clutch are cracks on the surface of the pressure disk or the ledged disk friction linings, the wear of the friction linings, the warning or rover of the disc, the weakening of the rivets of the fastening of the linings or hubs, wear and extension of the work surfaces of the pressure and middle disks. Discs and friction linings with cracks are braked. Worn friction linings replace new. For this remove old rivets.

They rule the slave disk, after reading the fears and burrs on the hub. The charging is installed at the test plate using the probe. A 0.3 mm thick dipstick should not pass between the end of the disk and the stove. Screwing friction linings produced under the press using a stamp. Instead of rivets, glue is also used to connect friction linings with disk. Swim disk with a slave disk of no more than 0.15mm or the beaming of the driven disk more specified in technical conditions Values \u200b\u200bare eliminated by editing. Purpose disk rule on the press, setting on the ring located on the press table, the touch plane to the slave disk down. Edit the slave disk is carried out on the plate or in the device with a special mandrel. The lining is remembered if they are weakened by the rivets of fastening them to the slave disks.

With a weakening of more than four rivets fastening the hub of the slave disk produce a replacement of rivets. For this, worn holes in the hub and disk are drilled under the increased repair size or drill new holes between the available. The renovated slave disk in the assembly with lining should be balanced. Permissible imbalance is established by specifications. Wearing and jackets of the working surface of the pressure and middle disks are eliminated by processing on a grinding or lathe. In this case, the minimum thickness of the disk should be no less specified in the technical conditions. After assembly, the clutch is installed on the engine and check its operation in the off and on positions.

For providing free coupling Turning off the clutch as the slave disks are wear out. There is a need to adjust the clutch drive. The drive of inclusion of clutch in KAMAZ cars - hydraulic. Adjusting the drive mechanism for turning off the KAMAZ clutch is to check and adjust the free move of the clutch pedal, the free stroke of the clutch of the clutch and the full run of the pusher of the air cooler. To determine the free move, the clutch clutch move the lever of the shaft of the adhesion of the adhesion from the spherical surface of the nicketer 18 of the pusher 17 (see Fig. 3.2, a) of the pneumulator with a disconnected position of the exhaust grip sprite from the lever.

If the free course of the exhaust clutch lever, measured on a 90mm radius, will be less than 3 mm, then it is adjusted with a nut 18 to a value of 3.7 ... 4.6 mm. This corresponds to the free move of the clutch clutch 3.2 ... 4m. Coupling pedal free KAMAZ cars are measured in the middle part of the coupling pedal 1 (Fig. 3.2, a). It should be 6 ... 12mm. The free move is regulated by a change in the gap between the piston and the piston of the main cylinder 9 eccentric finger 6 connecting the upper eye of the pusher 7 with the lever of 5 pedals. The operation is performed under the pressed clutch pedal to the upper stop 4 of the exhaust spring 8. The rotation of the eccentric finger is to achieve the required movement of the pedal from the top stop until the piston pusher is touched. Then tighten and screw the nut.

Clutch shutdown mechanism drive: a - hydraulic cars KAMAZ; b - mechanical cars ZIL: 1-pedal of clutch; 2-bottom stop: 3-bracket; 4-top emphasis; 5th lever; 6-eccentric finger; 7-piston pusher; 8 and 23 stretch springs; 9-main cylinder; 10- hydrolynium (hose); 11-front airmill case; 12-rear body of a pneumatic vehicle; 13-cork; 14-bypass valve; 15-pneumatic 16-protective case; 17- piston piston piston; 18-spherical adjusting nut; 19-reduction valve; 20-trail with spring; 21-adjusting nut; 22-lever fork; 24-plug clutch shutdown; 25-clutch clutch clutch with extrusion bearing; 26-Returning Spring

When adjusting the free stroke of the clutch pedal with a mechanical drive (Fig. 3.2, b) turns into several revolutions of the knitting nut 21, rotate the nut 21, changing the length of the thrust 20. To increase the free stroke of the nut 21, it is rejected, and to reduce it. After adjustment, holding the nut 21 fixed, delay until the lock nut failure.

Full pusher pusher pneumatic Check after pressing the clutch pedal until it stops. For KAMAZ cars, it should be at least 25mm. At less progress, it does not ensure complete clutch shutdown. In case of insufficient movement of the pusher of the pneumatic vehicle, check the free stroke of the clutch pedal, the volume of the fluid in the main cylinder of the clutch drive and, if necessary, pump the hydraulic system of the clutch drive.

The level of the "Neva" fluid in the main cylinder tube of the clutch shutdown mechanism Car KAMAZ is checked by a probe from the driver tool kit. The normal level of fluid in the hydraulic cylinder corresponds to 40 mm of the length of the moistened surface of the probe, permissible - 10mm. The total volume of fluid in the clutch hydraulic industry is 280cm 3. Once every three years, the liquid in the clutch hydraulic system is replaced in autumn.

Pumping Coupling Drive Hydraulic System KAMAZ cars are performed after eliminating the hydraulicity of the hydraulic nature in such a sequence: 1) purified from dust and dirt rubber protective cap of the bypass valve 14 (see Fig. 3.2, a) and remove it. Put on the head of the valve rubber hose attached to the car. The free end of the hose is placed in a glass vessel with brake fluid; 2) sharply click on the clutch pedal 3-4 times. When the pedal is pressed, the air outlet valve is rejected by 0.5-1.

Through the hose it will be part of the liquid and air contained in it in the form of bubbles; 3) After the release of the fluid is stopped under the clutch pedal, the connected valve wrap; 4) Operations 2 and 3 are repeated until the separation of air from the hydraulic system is completely stopped. In order to avoid entering the air system in the process of its pumping, liquid is periodically added to the system. Its level in the compensation cavity of the main cylinder should not decrease by more than 2/3 height from the level of normal level; 5) At the end of pumping, when the pedal is pressed, the bypass valve is completely wrapped, removed from its head the hose and install the protective cap on the valve head; 6) plot the liquid into the main cylinder to normal. The quality of pumping is determined by full go Clutch drive pusher.

Control and drain condensate In the hydraulic cylinder of the car, KAMAZ vehicles are carried out after rejection of the plug 13 (see Fig. 3.2, a) in the front case of the pneumulator. For complete removal of condensate, the cylinder is blocked by light pressed on the clutch pedal.

Clutch lubrication and washing hydraulic systems drive Consider on the example of the clutch of cars KAMAZ. The clutch shutdown sleeves are lubricated through two press oils 3 (Fig. 3.3), and the bearing of the clutch off clutch - through press oil with 2 syringe. In order to avoid lubricating material from entering the clutch crankcase, the number of swing syringe should not exceed three.

Fig. 3.3. Clutch lubrication points and gearboxes with car divider KAMAZ: 1-Sapun; 2-Press Oil Released Bearing; 3-Press Oil Support; 4 and 5-drain plugs with a magnet; 6-plug of the filling hole with a level pointer; The 7-cork of the drain hole was washed with hydraulic effect of the adhesion drive with technical alcohol or pure brake fluid with periodicity at least once every three years. In this case, completely disassemble the main cylinder and the pneumatic selection. Pipelines after washing are purged with compressed air, pre-disconnecting them from both ends. Calculated, worn, or with damage to working edges cuffs are replaced with new ones. Before assembling pistons and cuffs lubricate the brake fluid. After filling the hydraulic system of the adhesion of the fresh brake fluid, it is pumped to remove the air appeared.

To replace the clutch hydraulic pneumatic KAMAZ cars need to do the following: release air from pneumatic reception brake system through the valve on the air cylinder; Remove the exhaust spring 8 (see Fig. 3.2) lever 5 shaft fork clutch shutdown; Disconnect the pneumatic drug 15 of the air and hydrolynes 10; drain liquid from the hydraulic system; Two bolts of the fastening of the pneumausleter and remove it along with the pusher 17. Install a pneumatic fuel in such a sequence: fix the amplifier on the clutch crankcase (divider) with two bolts with spring washers; Appeal hydrolyna 10 pneumatic dealers and pneumatic drug 15;

set the exhaust spring 8 shaft of the clutch shutting down; pour the brake fluid into the compensation cavity of the main cylinder through the upper hole when the protective case is removed; pump the hydraulic system; Check the tightness of the connection of pipelines; eliminate the leakage of the brake fluid by a suspender or replacement of individual parts; Check and, if necessary, adjust the clearance between the cover of the lid and the stroke of the rod turning on the transmission.

Clutch faults

KAMAZ is a historical truck used for various purposes. Despite the age of technology, it is often used to transport heavy loads, such as sand and crushed stone. Thanks to their work, a large number of residential buildings and other buildings were erected. In Soviet times, KAMAZ was the most common motor vehicle, so everyone heard about the "KAMAZ - repair of their own hands."

Since that time, practically nothing has changed, and KAMAZ as popular and remained. The difference consists only that new, more modern and improved vehicles came to the change of old car models. But be that as it may, the whole technique sooner or late fails, and the KAMAZ is not an exception. Therefore, the repair of this technique is only a matter of time.

Since drivers trucks In most cases, they are driving, they often have to repair motor vehicle Alone. Naturally, it is not about carrying out full-fledged repairs, since KAMAZ overhaul provides for certain tools and spare parts. And the driver is not able to carry out all this, and there is no need. The essence of repairs is to eliminate small breakdowns that impede the movement of the machine into the nearest maintenance item.

The main way to prevent breakdown is prevention. This is especially true when it comes to KAMAZ car. The nuance is that the manufacturer's plant has its own auto transportation recommendations. Such recommendations must be followed during the first test period, which is 1 thousand km. If you look mostly, the recommendations relate to the speed and overload of the car. Included with the machine there is a guide "KAMAZ - repair with your own hands."

The main purpose of the repair is to prevent more complex breakdowns. The main preventive work includes the periodic replacement of all fluids (as required by the rules for the operation of the car). All fluids, especially cooling and lubricating, must be selected by all the rules and requirements. You can not pour into the car inappropriate fluid.

If there is a flow in the cooling system, problems with gaskets and valves, they must be immediately eliminated. If the breakage has not been eliminated after detection, it can lead to more serious problems. Separately, a block or liquid pump can be released.

As for the heart of the car - the engine, its repair must be carried out only when the alarm signaling device will turn on, which indicates pressure in the lubrication system. With a burning alarm, it is undesirable to continue movement. It is necessary to stop the car and find out the cause of the problem. Only after eliminating the breakage can be continued. "Kamaz repair with your own hands", whose video can be found on the Internet, is a unique benefit, especially when it comes to the engine.

1. If during the operation of the car, the cooling system liquid was leaked, it is possible to solve the problem with the help of water, which is fed into the system. This is enough to get to the maintenance station.
2. If the machine often drives dirt, then it is necessary to regularly clean the radiator from it, which will save from the repair of this component of the cooling system. It is necessary to rinse with water, but so that it sprinkles on the generator.
3. Before towing a car, you need to remove the cardan shaft. It will save the car gearbox from repair.

Thanks to such advice and preventive work, you can postpone the repair of the car for a long time.
