7.1. Forward suspension bracket

Forward suspension bracket — independent with cross levers and telescopic hydraulic damping racks of Mac-Ferson with twisted cylindrical springs, with the stabilizer of cross stability. The lower levers fasten to a cross-piece of a forward suspension bracket. In the top support of a telescopic rack the rubber buffer and the persistent bearing providing a possibility of its turn at turn of wheels is located. In a suspension bracket shock-absorbers of bilateral action are used. Rotary fists connect to the lower levers via spherical hinges.

The stabilizer of cross stability is executed in the form of a bar of round section which fastens to a cross-piece of a forward suspension bracket and transmits load of levers through racks of fastening of the stabilizer. Naves of wheels rotate on the two-row radial-stop bearings installed with a tightness in rotary fists.
