A free-wheeling unit (8) is arranged between a hub housing (4) and the drive element, for decoupling the drive element in a rotational direction of a rotational movement of the housing. A hub unit bearing device (7) is arranged between the secondary portion (3b) of the drive element and inner side of the hub housing for rotatably supporting the drive element with respect to the hub housing. The essential concentric hub axle is arranged in the hub housing. The hub axle is rotatably mounted with a drive element having a main portion (3a) with a freewheel (5) for receiving a ring gear.</p> |
