Pic. 1. Rear suspension (left-hand side): 1 - shock absorber; 2 – rear suspension arm; 3 – the bottom laying of a spring; 4 - rear suspension spring; 5 – the top laying of a spring; 6 – jet rod mechanism Watt; 7 - rear suspension beam; 8 – rocker mechanism Watt; 9 – cross member Watt mechanism
Rear suspension (pic. 1) semi-dependent, lever-spring, with trailing arms 2, hinged on the car body and interconnected by a U-shaped cross-section beam 7.
trailing arms B (pos. 2 in fig. 1) connected through silent blocks IN with brackets A, mounted on the body.
Springs 4 (see fig. 1) variable stiffness suspensions (barrel-shaped).
The upper and lower ends of the springs rest on elastic pads 3 and 5.
A torsion-type anti-roll bar is installed in the rear suspension beam.
The lower ends of the double-acting hydraulic telescopic shock absorbers 1 are bolted to the suspension arms. The upper ends of the shock absorbers are attached to the body with brackets.
A protective cover is put on the shock absorber rod, which simultaneously plays the role of a compression buffer.
The rear wheel hubs are fixed to the beam levers with four bolts each for the trunnion flanges. The hubs are equipped with double-row angular contact bearings.
The rear wheel alignment angles are predetermined by design and are not adjustable in operation. It is only possible to control the condition of the rear suspension at the installation angles (see Checking and adjusting wheel alignment).
To increase the lateral stability of the car when driving in corners, the Watt mechanism was used in the rear suspension, consisting of two jet rods A, attached to the trailing arms and interconnected by a rocker arm B through a rigid central hinge IN.
1. When checking, carefully inspect the rubber bushings of the lower..
2.... and upper shock absorber joints..
3.... shock absorbers (fluid leaks and «sweating» not allowed)...
4.... and rubber-metal hinges (silent blocks) fastening the arms of the rear suspension beam to the brackets on the body.
5. Check rear wheel bearings, springs and compression buffer.
Note. Pay attention to the exhaust system. Extraneous knocks published by her are often mistaken for knocks in the rear suspension. The use of non-standard parts or the breakage of the muffler suspension elements can cause a strong knock, especially during regassing. To check, stop the engine, carefully inspect the exhaust system, check the reliability of the mounting and suspension of the muffler. Grasping the end of the exhaust pipe, shake the muffler up and down and from side to side - there should be no knocks.
