The rear suspension beam consists of two trailing arms connected by a u-shaped cross member. This section provides the connector (cross member) greater bending stiffness and less torsional stiffness. The connector allows the levers to move relative to each other within a small range. The levers are made of a pipe of variable section - this provides the necessary rigidity. Brackets are welded to the rear end of each lever for attaching a shock absorber, a rear brake shield and a wheel hub axle. At the front, the beam levers are bolted to the removable brackets of the body side members. The mobility of the levers is provided by rubber-metal hinges (silent blocks), pressed into the front ends of the levers.
Rear shock absorber spring and parts: 1 - spring; 2 rubber gasket; 3 - casing cover; 4, 10 - cushions of the shock absorber rod; 5 - spacer sleeve; 6 - shock absorber casing; 7 - rod nut; 8 spring washer; 9 - support washer; 11 - shock absorber rod; 12 - shock absorber body; 13 - lower support cup of the spring; 14 - a nut of a bolt of the bottom fastening of the shock-absorber; 15 - eye; 16 - shock absorber lower mounting bolt; 17 - compression stroke buffer
The lower eye of the shock absorber is attached to the beam arm bracket. The shock absorber rod is attached to the body with a nut. The elasticity of the upper and lower connections of the shock absorber is provided by the pillows of the rod and the rubber-metal bushing pressed into the eye. The shock absorber rod is covered with a corrugated casing that protects it from dirt and moisture. In the event of suspension breakdowns, the shock absorber stroke is limited by a compression stroke buffer made of elastic plastic.
The suspension spring with its lower coil rests on the support cup (stamped steel plate welded to the shock absorber body), and the top one rests against the body through a rubber gasket.
The axle of the rear wheel hub is mounted on the beam arm bracket flange (it is attached with four bolts). The hub with a double-row bearing pressed into it is held on the axle by a special nut. The nut has an annular collar that locks the nut when it is jammed into the axle groove. The hub bearing is of a closed type and does not require adjustment and lubrication during vehicle operation.
