Rear suspension - dependent. The rigid beam of the rear axle is suspended from the body on five rods, four longitudinal and one transverse. The lower longitudinal bars are longer, the upper ones are short. Due to its attachment to the rear axle with an offset relative to the axis of the wheels, each pair of rods perceives reactive moments during acceleration and braking of the car, which is why the rods are called reactive. In addition, they transmit pushing and pulling forces from the rear axle to the bodywork. The cross bar is located behind the rear axle beam, it keeps the rear axle from lateral movement. All rods are connected to the body and the rear axle by rubber-metal hinges (silent blocks).
Elastic suspension elements consist of two coil springs, two main and one additional compression stroke buffers. The lower ends of the springs rest through insulating plastic spacers on cups welded to the rear axle beam. The upper ends of the springs are installed in the support cups of the body through rubber insulating gaskets. The main rubber buffers of the compression stroke are placed inside the springs and are attached to the body. An additional buffer is fixed on the bottom of the body above the rear axle housing. The buffer takes the load only when the car is moving on a rough road at high speed, overloaded or when the main buffers are destroyed.
Vibrations of the rear axle are damped by two twin-tube telescopic oil shock absorbers. In them, the vibrational energy is converted into heat by pumping liquid through calibrated holes. The lower and upper ends of the shock absorbers are connected, respectively, to the rear axle beam and the body by bolts also through rubber-metal hinges.
