REAR WHEEL SUSPENSION Russian patent published in 2019 - IPC B60G11/00 

FIELD: motor vehicle industry.

SUBSTANCE: invention relates to car suspensions. Rear suspension of car wheels comprises rear axle beam, reactive bars, telescopic hydraulic shock absorbers and air springs. Pneumatic springs comprise bellows-type air balloons and hollow pistons. On upper end along axis of piston are installed buffer of maximum compression stroke and air damper made in form of throttle and check valve communicating cavity of pneumatic cylinder with cavity of piston. Suspension is equipped with inertia-friction damper resiliently installed behind rear axle beam middle part on swinging lever. Lever is connected with additional hydraulic shock absorber and has two lugs. One lug is connected via axle to rear beam of axle by means of bracket, and the other one – to one end of torsion shaft. Other end of the shaft is rigidly fixed on the beam of the rear axle next to one of the wheels. Inertial-friction shock-absorber is made in form of planetary reduction gear. On the output shaft of the reduction gear flywheel is installed through the friction with possibility of axial movement and rotation relative to the output shaft. On the input shaft there is a rotary lever, on the end of which there is a traction rod. Throttle axis crosses axle of swinging lever and torsion bar.

EFFECT: higher smoothness and vehicle stability.
