ABSTRACT:
A wheel-mounted drive system usable for a sprocket wheel of a chain-drive vehicle has a nonrotatable two-part housing adapted to be mounted directly and substantially immovably on the vehicle frame. A hydraulic motor is mounted in one part of this housing and has a motor output extending through the other part of the housing which contains a transmission whose input is connected to the motor output and whose output is directly connected to the drive wheel and to a brake. A bearing rotatably mounts the transmission output directly on the housing. The brake can be pressurized through axial passages extending through the main shaft of the motor. The transmission includes planetary gearing, and the motor, transmission, and output member are all rotatable about the same central axis.
