VAZ 2107: Scheme and rear axle
Rear axle, plays a very important role for vehicle with rear-wheel drive. On the VAZ brand machines, starting from 2101, and finishing 2107, the rear axle had a heavier device than on the front-wheel drive samples. It includes mobile mechanisms forcing the rotation from the engine, directly to the drive wheels of the car. A detailed device and principle of work, we will look at this article, on the example of VAZ 2107.
Device and principle of operation
The rear axle of the VAZ 2107, consists of two parts: a cardan shaft, and the rear axle, with a gearbox. Cardan - consists of two semi-axes having a moving joint. It is located under the bottom, along the entire body, from the gearbox to the gearbox. It rotates with gear gears, and when the rear axis is shifted up or down, the cardan, also changes its position in order to ensure further rotation of the rear wheels.
Reducer - consists of metal casing, in which two gears are located. Some of them are at the end of the cardan shaft, perpendicular to the second, located on the beam of the rear axle. They have a diagonal cross section, which allows them to come into contact with each other, thereby ensuring the transmission of rotation.
Since the gearbox is a device in which the parts constantly occurs, and, accordingly, their heating, it should have a liquid in itself, providing lubrication of rubbing parts, and removal of heat from them. Usually, this fluid is enough for quite a long time, and its replacement is made very rarely. Such stability of the useful properties of oil is ensured by maintaining the correct atmospheric pressure, within the rear axle gearbox, which provides "Sapun".
Capuna consists of two parts: a glass, inside which is located an elastic balloon. It is he who connects the gearbox with a crankcase.
In addition to two main gears, the gearbox includes two pulleys responsible for the rotation of the left and right rear wheel. On this, the device and principle of the rear axle are completed.
Faults and their elimination
The gearbox device, and the rear axle as a whole, quite steady wear, and the malfunction with this node appear quite rarely. But, nevertheless, there are cases when some kind of mechanisms fail. What breakdowns happen most often, and what to do in such a situation, consider further in the article.
The first thing that suggests the driver about breakage - noise in the area of \u200b\u200bthe rear axle. It can proceed from two sources: gearbox and wheels. If the noise is heard from the rear wheels, then you need to check the axis attachments to the wheels themselves. Sometimes there are cases that the attachments are not fully tightened, and in the ride process, from constant vibration, they are spinning, and the backlash appears. It is he who contributes to the appearance of noise.
A more serious problem may be a breakdown, or wear of the ball bearing located on the semi-axis. In this case, the movement is categorically forbidden, since the wheel, may fall over at any moment. To eliminate this problem, you need to raise the damaged part of the car VAZ 2107, with the help of a jack, and replace the bearing.
If, when driving a car, the noise comes from the gearbox, the reasons may be a little more. The first, and the most frequent cause - the deformation of the rear axle. This often happens with a strong impact of the wheel about any obstacle. Eliminate such a breakdown, you need using specialists, since however that the rear axis will be, its noise level depends.
The second reason, which is found quite rarely - wear of the slots of the semi-axle or gear gear. In this case, the repair will not help, but only the replacement of parts for new ones are needed. But before changing them, you need to understand why gears or slots were worn out.
The gearbox device provides for heat removal from contact with each other, elements, as well as their lubrication. If, parts are wear out, then the most likely cause is the low oil level, or its absence.
In order to check if there is no leakage in the gearbox, pay attention to Sapun. If on it, or on the places of its compounds, there are oil drips, then the reason will be confirmed. It will not be very easy to fix it.
At first, the "Sapun" should be replaced with a new one. If after one - two trips, the drips are formed again, and on the same places, then, "Sapun" is not here. In this case, the breakdown is in the gearbox oil, which is considered a more serious malfunction.
In general, "Sapun" is not necessary to change to a new one, and it is enough to have several manipulations over it, in order to restore its performance. This, of course, will take a lot of time, but will help you save money.
Sapun Carter
The first thing to be done in order to "Sapun" has earned - to clean it from dirt and dust, since when the oil is heated, contamination data will interfere with the stabilization of atmospheric pressure, and, accordingly, prevent the cooling of the liquid.
The second manipulation is the purchase of Remcople to Sapun. It often happens that it happens that the valve is placed inside the "Sapuna" device, and when heated, the oil does not go into the crankcase, but the glands are pushing, and it comes out. From there and appear implications.
Here we have got acquainted with the device and the principle of work, the rear axle of the car VAZ 2107. Now, when it breaks, you can determine the cause, and it is fairly quickly eliminated.
