SHRUS - what kind of detail is it and how is it arranged?


Surely every car owner was surprised when inthe first time I heard the abstruse and sometimes magical names of spare parts and aggregates of my iron friend. And today's speech does not go at all about cylinder head (cylinder head). Today we will devote attention to such a mechanism as the SHRUS.

It's not a magical name, it's justabbreviation. Shortly the CV joint is a hinge of equal angular velocities. The task of this mechanism is to transfer the rotational motion of one half-axis to the other in the case when both are at a certain angle relative to each other. The value of this angle is always variable.

At first glance motorists, especiallyfor beginners, it seems that the SHRUS is a complex multifunctional detail, the device of which is known only to experienced designers. In fact, the SHRUS (VAZ 2110 or "Renault Logan" - it does not matter) is very primitive in its design, due to which it has a long service life.

SHRUS is a detail consisting of only 4 knots:

  • a spherical body with a driven shaft;
  • six balls;
  • separator, which is a ring with a hole to hold the previous elements;
  • inner cage.

Due to its simple design, it canlast longer than any other suspension mechanism. Probably, this is why the SHRUS is not given such special significance as anthers, shock absorbers and filters.

All these four elements allowmechanism for the transfer of rotational motion, and very evenly. What is noteworthy, the cardan joint of the semi-axes, which in fact performs a similar function, does not possess the same capability as the CV joint. This is a unique detail, which for some reason no one gives much importance. In contrast, the cardan joint can not transmit the rotational motion so uniformly. If the first semiaxis is working smoothly, then the second semicircle transmits the movement intermittently.

How does this mechanism work?

The principle of the CV joint can be divided into 4 stages:

  1. On the inner cage and inside the body of this part there are spherical grooves. Their quantities

  2. The last elements are retained in the CV joint athelp the separator and are located between the fist and the body. The balls move along the grooves of the body and the fist (along the outer and inner diameters, respectively).
  3. When the drive shaft rotates, the force from rotation is transferred to the cage, and then to the driven shaft.
  4. When the angle between the two shafts changes, the balls move along the grooves in the free direction while continuing to transmit the force.

    Proceeding from this, we see that the SHRUS is not really so complicated in design and principle of operation.

Replacement of CVCC CVDs - the main signs

In view of the fact that this part is verya reliable element of the running gear, the first 60 thousand kilometers for its condition can not be at all worried. However, if in time to replace the anthers of the CV joints, this problem can affect you much earlier. The main signs of the breakdown of this part is a characteristic knock, and more often the crunching of the parts during the rotation of the driving wheels.
