The rear suspension beam consists of two longitudinal arms connected by a U-shaped cross member. This cross-section provides the connector (crossbar) greater bending rigidity and less torsional rigidity. The connector allows the levers to move relative to each other within a small range. The levers are made from a pipe with a variable cross-section, which gives them the necessary rigidity. Brackets for mounting the shock absorber, rear brake shield and wheel hub axle are welded to the rear end of each arm. At the front, the beam arms are bolted to removable brackets on the body side members. The mobility of the levers is ensured by rubber-metal hinges (silent blocks), pressed into the front ends of the levers.
The lower shock absorber eye is attached to the control arm bracket. The shock absorber is attached to the body with a rod and nut. The elasticity of the upper and lower shock absorber connections is provided by the rod cushion and the rubber-metal bushing pressed into the eye. The shock absorber rod is covered with a corrugated casing, protecting it from dirt and moisture. When the suspension "breaks down", the shock absorber rod travel is limited by a compression buffer made of elastic plastic.
The suspension spring rests with its lower turn on the support cup (stamped steel plate welded to the shock absorber body), and the upper one rests against the body through a rubber gasket.
The rear wheel hub axle is mounted on the beam arm bracket flange (it is fastened with four bolts). The hub with a double-row roller bearing pressed into it is held on the axle by a special nut. The nut has an annular flange that securely locks the nut by pressing it into the groove of the axle. The hub bearing is closed and does not require adjustment or lubrication during vehicle operation.
