HYDROPNEUMATIC INDEPENDENT SUSPENSION OF WHEELED VEHICLE MODULE Russian patent published in 2019 - IPC B60G17/04 

FIELD: machine building.

SUBSTANCE: invention relates to hydropneumatic independent suspensions. Hydropneumatic independent suspension of the wheel module contains a wheel, an integrated hydraulic motor, a guide post, and a hydraulic cylinder with a rod. Lower end of the rack is rigidly connected to the engine block. Rack suspension is made in the form of a hollow cylinder with a bottom and mounted on a frame with bearings. Inside the rack there is an axially movable part of the suspension, made in the form of a pneumatic cylinder with a floating piston and a hydraulic cylinder that was manufactured at the same time. Free end of the rod having a channel is connected to the bottom of the rack. Pneumatic cylinder is connected by means of controlled valves to the air line, and the hydraulic cylinder is connected to the pressure hydraulic line of the accumulator. There is a stepper hydraulic motor with a gear wheel on the frame, which interacts with a gear sector made on the outer surface of the rack. Slots are made on the mating surfaces of the rack and the pneumatic cylinder. Rolling bodies, for example, balls are installed in the spline joint. Compression buffer is installed in the rack. Pneumatic accumulator and a pneumatic compressor are connected to a pneumatic route by means of a controlled valve.

EFFECT: compact suspension with enhanced functionality is achieved.
