An axial bearing device includes an axle (11), a mechanical coupling site (20) for a reduction stage (2) and a mechanical coupling site (21) for a male screw thread (22) and a bar (23). The male screw thread and bar convert the rotation of the transmission mechanism into longitudinal movement and vice versa. A force (F) along the axis of the axle is transferable to a stationary gear (16). The axial bearing device has a construction such that the effective bearing friction in one rotation direction is different from that in the other rotation direction. |
