摘要

The device has a circulating axle (5) with a rope coil (2) that is coupled with the axle in a force-fit manner. A hub body (7) is rotatably surrounded by an outer body (8), where a hydraulic brake device (6) is arranged between the hub body and the outer body. The coil is coupled with the axle using a transmission gear, where the bodies and the brake device are arranged on the axle of the coil. The hub body is formed as a roll body with wing plates. A control valve is arranged in a ring line that connects compressed and expanded sections of an annular passage.
