Back suspension bracket – dependent, with a cross beam on which longitudinal levers, with the cross directing bar, twisted cylindrical springs, the stabilizer of the torsion type and telescopic hydraulic shock-absorbers are welded.
On a rod of the shock-absorber the rubber buffer 22 courses of compression of a suspension bracket, and inside – the polyurethane limiter of the course of a release is outside installed.
The design of the shock-absorber is unified with two-pipe shock-absorbers of forward and back suspension brackets of the Muscovite-2140 car. Differences consist in length and the course, a structure of connecting places, sizes of forces of resistance, existence of buffers of a release and compression. Besides, the shock-absorber has no protection cover as the shock-absorber is installed in a niche of a mudguard of the body protecting its rod from pollution and damages.
At the movement of the car a backing in order to avoid damage of levers and a beam of a back suspension bracket it is necessary to be careful – not to allow blow by a beam against obstacles, to avoid arrival by back wheels with blow on obstacles of type of an onboard stone and hit of back wheels in deep dredging on the road.
When pulling of the got stuck car (dirt, a deep track, etc.) it is not necessary to use a cross bar and a beam of a back suspension bracket for fastening of cables or ropes.
When posting a back part of the car it is not necessary to rest a jack and to substitute the support under average which do not have amplifiers a part of a beam of a back suspension bracket.
In a nave of a back wheel not greased two-row radial-stop ball bearing 2141-3104020 (6-256907E1017) with bilateral consolidation, but smaller dimension is installed as well as in a nave of a forward wheel. As the option can be established the two-row radial-stop roller bearing 2141-3104020-01 (6U-537907S17). On an internal and external ring landing is carried out with a tightness. The bearing drags on on a pin tail a nut with the rumpled fillet: moment of an inhaling of 140-160 N · m (14–16 kgfs · м).
Operating conditions of the bearing of a back wheel are similar to operating conditions of the hug bearing of a forward wheel.
Needlessly it is not necessary to press off the bearing from a nave as the vypressovka leads to damage of the bearing.
