Surely every car owner was surprised when I first heard of abstruse and at times magical names of spare parts and components of your iron friend. And today it does not go on the cylinder head (the cylinder head). Today we will devote attention to such mechanism as the universal joint.joint it

This is not a magic name, just the abbreviation. Abbreviated CV joint - CV joint. The objective of this mechanism is to transfer rotary motion of one axle to another when both are at a certain angle relative to each other. The value of this angle is always variable.

At first glance, car enthusiasts, especially beginners, think that the CV joint – this is a complex multifunctional detail of the device known only to experienced designers. In fact, the joint (2110 or “author” - does not matter) is very primitive in its design, due to which it has long service life.

Joint – this item, consisting of only 4 nodes:

  • Spherical body with the slave shaft;
  • Six balls;
  • Separator, which is a ring with a hole to hold the preceding elements;
  • Internal cage.

With its simple design it can last longer than any other suspension mechanisms. Perhaps that is why Srus do not attach such special significance, as the anthers, shock absorbers and filters.replacing CV joint VAZ

All of these four elements allow the mechanism of transmission of rotational motion, and very smoothly. Remarkably, universal joint axles, which essentially performs a similar function, does not possess the same capacity as joint. This is a unique item, which for some reason nobody gives a special value. In contrast, the cardan joint is not so uniformly transfer the rotational movement. If the first radius works smoothly, then the second transmits the movement intermittently.

How this mechanism works?

The Principle of operation of the constant velocity joint can be divided into 4 stages:

  1. On the inside of the cage and inside the body this part is a spherical groove. Their quantitativeCV joint VAZ 2110Coincides with the number of balls.
  2. Recent items are held in Cruse in a separator and located between the fist and the housing. The balls move in the grooves of the housing and the fist (on the outer and inner diameter, respectively).
  3. When the drive shaft rotates, the force from rotation is transmitted to the clip, and then – to the driven shaft.
  4. When the angle between the two shafts changes, the balls move in the grooves in the free direction, continue to transmit force.

    From this, we see that the joint is actually not so complex in design and operation principle.

Replace the CV joint VAZ – the main signs

As this item is a highly reliable element of the chassis, the first 60 thousand kilometers for his condition it is possible not to worry. However, if not time to replace the CV axle dust caps, this problem may affect you a lot sooner. The main signs of damage the part is a characteristic knock, and more - crunch parts during the rotation of the drive wheels.
