MOTOR-WHEEL Russian patent published in 1994 - IPC

FIELD: transport engineering. SUBSTANCE: motor-wheel has a hydraulic motor, a wheel reduction gear with a drive wheel fastened to it, and a device for eliminating the kinematic link between the hydraulic motor and the drive wheel made in the form of a gear coupling. The coupling has a stationary coupling member and a gear bush and a movable coupling member with shaped slots on the side surface held in a fixed position by a spring and a rotary roller with radial projections. The movable roller is made through with inner end connected to the movable spring-loaded coupling member, and outer end - to a handle engageable with the projections on the reduction gear cover. The difference between the heights of bearing platforms of the projections is no less than the width of the gear rim of the movable coupling member. EFFECT: improved structure. 3 dwg
