HYDROSTATIC MECHANICAL WHEEL DRIVE |
摘要 |
<p>In a wheel drive with a radial-piston motor (5) and a planet gear (4) a wheel hub (3) being placed on a wheel hub support (1) by means of wheel bearings (10). The wheel hub support (1) can be joined to a transmission connector (4) in a single piece and is fastened to a vehicle chassis support. A dog tooth brake (7) is located on the side of the wheel drive facing the vehicle and serves as parking brake. In a cover (2) for a hydraulic connection of the radial-piston motor (5) are integrated valves for control of the radial-piston motor (5) and of the brake (7). Short lines and delay times occur as result. The cover (2) contains inter alia a brake valve (58) for a hydraulic brake function and a displacement change-over valve (64) enabling certain cylinders (70) of the radial-piston motor (5) to be switched on or off.</p> |
