<p>An arrangement is provided for, by means of a motor, driving a motorcycle wheel which can be arranged on a wheel axle. Via its hub and via bearing means, the wheel can be mounted on the wheel axle which is mounted in a vehicle part or vehicle parts. The hub comprises a side recess, and the motor can be arranged on a part mounted on the axle and extending at or in the side recess of the hub, through which part the driving means (for example driving shaft) of the motor extend for interaction with movement-transmitting means in order to bring about rotations of the hub relative to the wheel axle. A part which, via a bearing means, is rotatable relative to the wheel axle is arranged so as to carry an inner gear rim. The rotatable part transmits its rotary movement to the hub/wheel. The rotatable part is located inside a casing or enclosure formed in the recess, which, together with the motor, constitutes a unit which can be separated from the wheel axle and the hub. The invention also relates to a device which forms an easily removable rotary unit.</p> |
