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