VEHICLE WHEEL SUSPENSION Russian patent published in 2009 - IPC B60G3/20 B60G11/56 

FIELD: motor industry.

SUBSTANCE: invention is related to the field of transport machine building. Vehicle wheel suspension comprises system of four levers, every of which is arranged with the possibility to be fixed with its one end in car body, and with its second end - in wheel axle box, spring support - shock absorber and hydraulic-pneumatic controlled shock absorber. Levers are installed in pairs in two planes, both along horizontal and vertical line. Each pair consists of upper and lower levers and creates parallelogram, where shorter sides make distances between axes of upper and lower lever on car body and wheel axle box. Two upper levers of each pair are connected by means of plate, onto which spring shock-absorber rests with its lower part. Upper part of shock-absorber interacting with extensible stem of hydraulic-pneumatic shock-absorber is arranged with the possibility of hinged fixation on car body. Body of hydraulic-pneumatic shock-absorber is arranged with the possibility of hinged connection to car body. Length of extensible stem of hydraulic-pneumatic shock-absorber provides for change in track width and clearance in case of its extension from body.

EFFECT: achieved improvement of car cross-country ability, due to change in track width and clearance height.
