1. A swinging arm motor unit having a rotating shaft (10) for single track or multiple track vehicles comprising an electric driving motor (14) disposed in a region of one end of an extended swinging transmission housing (12) and a wheel hub (16) for holding a driving wheel (18) of the vehicle mounted rotatably in a region of the other end of the swinging transmission housing, the electric driving motor (14) having a drive shaft passing into the swinging transmission housing (12) and forming a positive coupling with the wheel hub (16) of the driving wheel of the vehicle by a transmission device (26) encapsulated in the swinging transmission housing (12), the swinging transmission housing (12) being pivotably mounted about an axis at a distance from the axis of rotation of the wheel hub (16) and the swinging transmission housing extending parallel to the frame (52) or chassis (54) of the vehicle, and at least one overriding clutch being provided which cancels the positive coupling between the driving motor (14) and the driving wheel (18) of the vehicle when a driving moment initiated in the transmission device (26) by the driving motor (14) is smaller than a torque acting from the driving wheel (18) of the vehicle over the wheel hub (16) on the transmission device, wherein the transmission device (26) has at least two transmission trains (26a, 26b), each constructed as a belt or chain drive, which are connected in series, and one of the overriding clutches is connected between the two transmission trains (26a, 26b).
