7.1. Forward suspension bracket

Forward suspension bracket — independent with cross-section levers and Mac-Ferson telescopic hydraulic amortizatorny racks with twisted cylindrical springs, with the stabilizer of cross-section stability. The bottom 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 possibility of its turn at turn of wheels is located. In a suspension bracket shock-absorbers of bilateral action are used. Rotary fists incorporate to the bottom levers via spherical hinges.

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