The rear suspension of the car is dependent, includes a guide device, elastic elements and devices that dampen vibrations.
Guide device
The rear axle beam is hinged to the body, with the help of torque rods - two lower 3 and two upper 17 longitudinal and one transverse 22.
Longitudinal rods transmit pushing and braking forces from the drive wheels through the rear axle beam to the body, the transverse rod keeps the body from lateral displacements.
The reaction rods are attached to the body brackets and the rear axle beam through rubber-metal hinges, which are structurally the same and differ only in size.
The hinge consists of a rubber bushing 2 installed in the eye of the rod, a spacer sleeve 1, which passes through the hole in the rubber bushing of the thrust washer and the rod fastening bolt.
Elastic suspension elements
The elastic suspension elements consist of coiled coil springs 9, two main buffers 6 of the compression stroke and an additional compression buffer 16. The springs are sorted, under a static load of 295 kgf, into two groups: A and B.
Groups are marked similarly to groups of front suspension springs, i.e. group A - yellow stripe, group B - green. The spring mounted on the suspension rests with its upper end on the support cup 10 through the rubber insulating gasket 11, which is placed in the stamped steel cup 12 of the body. The lower end of the spring rests in the cup 5 of the rear axle beam through an insulating plastic gasket 4.
The main buffers 6 are installed inside the springs and are fixed with a mushroom-shaped nipple in the holes of the upper supports 10. The additional buffer 16 is mounted on a bracket bolted to the bottom of the body. At the end of the compression stroke, the main buffers rest against the disc-shaped bottom of the lower cup 5, and the additional buffer rests against a special platform on the rear axle gearbox housing.
Extinguishing device
The extinguishing device consists of two hydraulic shock absorbers, the device of which is described below.
