PNEUMATIC AXLE SUSPENSION FOR REAR AXLE OF VEHICLE Russian patent published in 2020 - IPC B60G9/02 

FIELD: transportation.

SUBSTANCE: invention relates to automotive suspensions. Pneumatic axle suspension for rear axle comprises elastic beams, pneumatic cylinders arranged on the frame, a pair of front brackets, a pair of hydraulic shock absorbers, lengthwise bars, a triangular rod and a stabilizer. Brackets extend downward from frame ahead of axle. Lengthwise rods extend between front bracket and resilient beam and are connected by their ends to front bracket and elastic beam. Triangular rod is connected with upper central section of axis and frame with possibility of rotation. Stabilizer has U-shape, is located above axis and is enclosed between two pairs of pneumatic cylinders. Stabilizer comprises transverse beam and two branches extending from ends of transverse beam in direction perpendicular to axis, in which transverse beam is supported to turn on pivot bearings. Bearings are installed in lower part of frame so that branches can perform swinging movement. Ends of branches are connected with possibility of rotation with axis by means of perpendicular tie-rods and axle supports. Each tie rod is pivotally connected to one end of branch and one axle bracket with possibility of rotation.

EFFECT: compact design and higher motion comfort.
