5.2.1. The design description

Suspension bracket — a link between a body and wheels. Through it the forces influencing wheels are transferred to a body. The suspension bracket serves for decrease in dynamic loadings, reduction of fluctuations of a body, softening of blows of wheels about roughness of road, provides stability and smoothness of a course of the car.

The forward suspension bracket consists of a rotary fist, a rack, a spring and the lever.

The lever shakes concerning a body. In the bottom lever the rubber plug is used. The top end of a rack is fixed on a body and consists of the bearing allowing a wheel to turn.

The bottom part of a rotary fist is fixed on the spherical hinge which is connected to the lever by means of a bolt. At service of fastening of the lever to a body and an insulator of the stabilizer from a body be convinced that fixing bolts are weakened so that the lever at качении will get before extremely top position of amplitude качения which also is normal position to which the lever when the car costs on the earth moves.
