1. After repairing the suspension:

replacement of steering tips;

replacement of ball supports;

replacement of the pendulum lever;

replacement of the steering gear or steering rail;

replacement of suspension levers;

replacement of silent blocks;

spring replacement (required: Repeated adjustment after 3-5 tons. Km mileage);

replacing racks or shock absorbers with oil on gas and gas or gas and vice versa, a change in the clearance of a car, which entails the change in the Wheel (wheel installation angles)

If the car takes to the side - right or left, and the steering wheel changed its position when moving in a straight line.

After changing the clearance (road lumen) of the car:

installations of spacers ("houses") or thickened rubber band under the pendant spring;

installations of shorter or higher suspension springs (required: Repeated adjustment after 3-5 tons. Km Mileage)

The car holds the road badly ("floats") or throws to the side when entering the pit and, especially, in a rings.

The car "Tupit" in management. Reaction to driving driving belated. Steering tight.

When braking the car takes (pulls) to the side or seeks to turn around on a slippery road (first need the diagnosis of the brake system)

If you get into a hole with the deformation of the disc, the blow of the suspension on the chippers, the departure of the steering wheel from the original position ("the steering wheel left is the convergence").

Increased rubber wear.

If the car has a different radius of reversal to the left and in the right and you want to align it (sometimes it is accompanied by hiding wheels for the arches when the steering wheel is turned to the stop)

Bad RETURN RETURN OWN COLLECTION (CASTOR)

After running a new car or if you recently bought a used car.

After replacing the winter rubber on the summer (in the winter you get into the pit - the angles go, the rubber is not "eating" -scolzko, it comes in spring and the rubber begins to "sweep").

After installing new rubber, especially if the car takes to the side. * Do not forget that new rubber must run at least 300-500 km and during running. Do not make sharp accelerations, braking - do not strain the rubber so that it serves longer. This is especially true of the studded rubber, since the spikes should fall into place in their nests, otherwise the "floating" spikes will become "flying away".

You can call some technical moments that suggest that your car is time to drive into the workshop. If you visually notice the uneven wear of tire tread. If you feel an effort on the steering wheel when moving in a straight line, or the machine goes aside when the steering wheel is released. If the car loses the course stability when it runs on unevenness, on the road. If you notice the increased noise of tires when moving the car. If you notice a sharp change in the position of the horizontal steering wheel.

All these moments suggest that the wheel alignment must be adjusted. It is impossible to adjust yourself in the garage. This requires special equipment.

What is collapse?

The wheel with the negative corner of the collapse. The collapse is the angle between the vertical and the plane of rotation of the wheel. The collapse is considered negative if the wheels are directed to the upper side inside, and positive, if the upper side is out.

The collapse is changing with the change in the roll of the car, and in MacPherson pendants - also with changing the download. In heavy trucks "Tatra", the collapse of the rear wheels on an unloaded car is so great that the car rides relying only on the outer tires.

Zero collapse provides minimal wear of tires. Negative collapse improves stability in turns. A positive collapse is applied only in two places: 1) on cars with MacPherson suspension, and 2) on sports cars designed for riding on oval, on inner wheels.

On double pendants, collapse, as a rule, can be changed. On vehicles with MacPherson suspension, a decrease in clearance by simple shortening of the springs will lead to a change in all four angles of wheels. To change the clearance, you need to change the entire suspension attachment node.

It was originally measured using plumbing and levels of various systems, or optical sensors with computer processing, or gravitational tilt sensors are currently used.

Measurement point:

A. Height from land to the front wheel center

B. Height from the ground to the center of the bolt of the bottom lever

C. Height from Earth to the center of the rear beam bolt

D. Height from land to rear wheel center

Note: Adjust the car height to standard values \u200b\u200bbefore checking the front wheel adjustment.

If the car height does not comply with standards, adjust it.

3- Verification of convergence convergence:

Convergence a + in o ° ± 12 "

If the convergence does not match the specification, adjust the left and right steering lever.

4. Adjustment of convergence (Fig.208)

(a) Remove the captain of the anther.

(b) Unscrew the nuts on the end of the transverse lever.

(c) Uniformly rotate the ends of the levers of the left and right rack to adjust the convergence (Fig.209)

If the left and right inner corner does not match the specification, check the length of the left and right rack.

6. Checking the collapse, longitudinal tilt and tilt of the steering shaft (Fig.211).

(a) Install the slaughter-tilt sensor or lift the wheel adjustment tester.

(b) Check the collapse, longitudinal slope and the tilt of the steering shaft.

Collapse, longitudinal slope and tilt of the steering shaft: (normal road)

(bad road)

If the longitudinal tilt and the tilt of the steering shaft does not match the specification, adjust the longitudinal slope and then check damage or wear the bottom lever parts.

7. Adjustment of collapse

Geely MK / Cross. Check and adjust wheel installation angles

Verification and adjustment of wheel installation angles are necessary to ensure good stability and car handling, as well as uniform wear of tires during its operation. Verification and adjustment of wheel installation angles are performed on special stands according to instructions for their operation.

The inconsistency of the actual values \u200b\u200bmeasured by car, the control values \u200b\u200bspecified in the specifications due to the wear and deformation of the parts of the suspension, the deformation of the body.

A warning

Replacing or repairing the parts of the suspension can entail a change in the angles of the wheel installation, so checking the angles of the wheel installation after these works are required.

The angles of the installation of the front wheels:

the angle of the longitudinal tilt axis of the wheel turn

cross-tilt angle wheel axis: Look in the vehicle specifications

the corner of the collapse : Look in the vehicle specifications

convergence : Look in the vehicle specifications

Rear wheel installation angles:

the corner of the collapse : Look in the vehicle specifications

convergence : Look in the vehicle specifications

Wheel installation angles Check by car with a ballast weighing 70 kg on each front seat, with half a fuel tank filled with a normal tire pressure, in the absence of excessive wells in the suspension nodes.

After installing the car onto the stand, immediately before checking the angles, the "Fel" the suspension of the car, applying two to three times the force directed from top to bottom to the rear bumper and then to the front. The wheels of the car must be located parallel to the longitudinal axis of the car.

Checking the angle of installation of the front wheels, first determine the corners of the longitudinal and transverse tilt axis axis of the wheel, then the angle of the collapse of the wheels and the last turn of the wheel alignment.

The angle of the longitudinal tilt axis of the turn of the front wheeleducated vertical on the side of the side and line passing through the middle of the top support of the telescopic rack and the center of the sphere of the ball support attached on the lower lever.

Cross-tilt angle of the axis of the turn of the front wheeleducated vertical on the sight of the front and line passing through the middle of the top support of the telescopic rack and the center of the sphere of the ball support attached on the lower lever.

The angle of the bells of the front wheelsit is characterized by the deviation of the middle plane of rotation of the front wheel from the vertical.

Note

Adjusting the angles of the longitudinal and transverse tilt axis of the axis of rotation, as well as the angle of the columns of the front wheels is not provided for by the design of the car. With the deviation of these angles from the nominal values, replace damaged and deformed parts.

The convergence of the front wheels is the angle between the plane of rotation of the front wheel and the longitudinal axis of the car. The forward wheel alignment is regulated by changing the length of the steering.

Rear wheel installation angles can be adjusted during operation.

The angle of collapse of the rear wheels is characterized by the deviation of the middle plane of rotation of the rear wheel from the vertical. The angle of the rear wheel column is regulated by the rotation of the adjusting bolts of the upper transverse lever to the body bracket and to the rear transverse beam.

The rear wheel alignment is the angle between the rear wheel rotation plane and the longitudinal axis of the car. The convergence of the rear wheels is adjusted by the rotation of the adjustment bolt, located on the inside of the control lever.

6. Connect the angular speed sensor wiring

7. Check the backlash backlash

8. Check wheel hub bias

9. Install the rear brake drum

4. Set the left rear wheel hub bolt

Chapter 5. Front Suspension System

Section 1 General Information about the front suspension

Description of the design of the front suspension

An independent suspension with a transverse stability stabilizer is installed on this car model.

The upper end of the shock absorber is attached to the top support, the bottom is rigidly attached to the swivel fist.

The shock absorber limits the spiral spring, (the geometric axis of the screw spring does not coincide with the geometric axis of the piston of the shock absorber). A restrictive buffer is installed on the shock absorber.

Both edges of the stabilizer rod are connected to the shock absorber using a rack with a rotary mechanism, and the intermediate part is installed on the lower front part of the body through the rubber bushings.

The thrust ball bearing installed in the support is designed to rotate the front rack around its axis.

One end "L"-like lever is attached to the body through silent blocks, the second end of the lever is attached using 3 bolts ball support. Finger ball support is inserted into the swivel fist. The ingested ball support are filled with lubrication capable of protecting effectively from wear and provide high support performance. During the assembly of the support, a sufficient amount of lubricant is lacked and there is no need for maintenance of support under normal operating conditions of the car.

The table below shows the main technical parameters of the front suspension.

Note: Wheel installation angles in the table are shown for a car without load
