HYDRAULIC WHEEL DRIVE Russian patent published in 2023 - IPC B60K7/00 F16H39/24 B60K17/14 

FIELD: hydraulic wheel drives.

SUBSTANCE: hydraulic wheel drive comprises a hydraulic motor, a wheel flange connected to the shaft of the hydraulic motor rotor. The centre pin and pivot of the steering knuckle are configured for turning the hydraulic motor relative to the axis of the centre pin. The hydraulic motor is a two-section rotary vane eccentrically mounted on the steering knuckle trunnion and configured for rotation around the trunnion axis. The hydraulic motor is pressed against the stop fixed on the steering knuckle by torsion springs mounted on the trunnion and resting with one end on the stop and the other end on the hydraulic motor. A chain drive star is installed on the steering knuckle to rotate the hydraulic motor relative to the centre pin axis.

EFFECT: increased reliability of the hydraulic motor wheel during operation.
