Basic element of a forward suspension bracket – the telescopic damping rack combining functions of a telescopic element of the directing mechanism and the damping element of vertical fluctuations of a wheel concerning a body. On a damping rack the twisted cylindrical spring, the compression buffer, the protection cover of a rack and the top support are collected.
The top support of a damping rack fastens to a body mudguard rack three nuts. Due to the elasticity the support extinguishes high-frequency fluctuations.
The damping rack is connected to a rotary fist a coupling bolt.
The lower part of a rotary fist is connected to a spherical support of the lower lever of a forward suspension bracket. Rotary fists are executed for a single whole with a pin. On a pin of a rotary fist of a forward suspension bracket establish a nave with the two-row radial-stop ball bearing pressed in it.
The lower levers are attached to a car stretcher by means of saylentblok.
The stabilizer of cross stability is connected to a car stretcher two brackets via rubber plugs, and to damping racks – stabilizer racks.
