Features of the rear suspension device (VAZ-2108)

The rear suspension beam consists of two longitudinal arms 15 (figure 98) and connector 14, which are welded together through amplifiers. At the rear, brackets 16 with lugs for attaching shock absorbers are welded to the suspension arms, as well as flanges 2, to which the rear wheel axles are bolted. At the front, the suspension arms have welded bushings 3, into which rubber-metal hinges 4 are pressed. A bolt passes through the hinge, connecting the suspension arm to the stamped-welded bracket 5, which is attached to the body side member with welded bolts. Suspension spring 12 rests with one end on the shock absorber cup 1, and the other through the insulating gasket 13 in the support welded to the inner arch (mudguard) body. A compression stroke buffer 7, closed by a cover 8 with a casing 6, and shock absorber mounting parts - a spacer sleeve 11, cushions 10 and a support washer 9 are installed on the rear suspension shock absorber rod.



Shock absorber 8 (figure 99) the rear suspension is hydraulic, telescopic, double-acting. It is attached with bolt 9 to the bracket of the longitudinal suspension arm. The upper shock absorber mount is pin-type: the rod is attached to the upper support 5 of the suspension spring through rubber cushions 6, cup 2 and support washers 3. An insulating gasket 4 is installed between spring 1 and support 5. The lower part of the spring rests against cup 7. The shock absorber parts are shown in Figure 100.

In the hub 13 (see figure 99) a double-row radial thrust bearing 12 is installed, similar to the front wheel hub bearing, but smaller in size. Unlike the front wheel hub, where the inner ring of the bearing is installed on the hub with a guaranteed tension, bearing 12 has a transition fit. It is fixed in the hub with a locking ring 16, and on the axle 14 with a nut 15. The wheel axle is fastened with its flange with bolts 10 to the flange of the rear suspension beam. Brake drum I is fastened to the wheel hub with bolts and mounting pins 17.

Possible faults of the rear suspension, their causes and methods of elimination are given in table 12.
