The suspension bracket of back wheels is equipped with trapezoidal levers. The beam of a suspension bracket is made of steel, trapezoidal levers - from the hollow aluminum shape. Such design is characterized by the insignificant weight and compactness. Thanks to it becomes possible to reach both at front-wheel option, and at the full drive of a low arrangement of a floor in a luggage carrier and the optimum width of a cargo compartment.

All lever elements through rubber-metal support are connected by hinges to elastically established suspension bracket beam that provides effective clearing of vibrations of a body. Podressorivaniye of a back suspension bracket is carried out by screw springs and two shock-absorbers which are located separately and easily act.

Carrying out welding and leveling works on the bearing and directing elements of a forward suspension bracket is not allowed. The self-stopped nuts, and also rusty bolts / nuts, when carrying out repair have to be replaced.
