The suspension bracket of back wheels is equipped трапециидальными by levers. The suspension bracket beam is executed from a steel, трапециидальные levers - from a hollow aluminium profile. Such design is characterised by insignificant weight and compactness. Thanks to it begins possible to reach both at a front-wheel variant, and at a full drive of a low arrangement of a floor in a luggage carrier and optimum width of a cargo compartment.

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

Carrying out welding and рихтовочных works on bearing and directing elements of a forward suspension bracket is not supposed. Self-stopped nuts, and also rusty bolts/nuts, at repair carrying out should be replaced.
