摘要
The invention relates to an electromotive drive unit (1) for a vehicle that can be driven by muscle power, comprising a stator (2), a rotor (3), a drive pulley (4) that can be driven via the rotor (3) and has a connection (5) to an endless traction mechanism (6), and a freewheel device (7) for realizing a freewheel such that the drive pulley (4) can be rotated at a lower speed than the rotor (3) with the same direction of rotation. The freewheel device (7) comprises a first coupling disk (8) and comprises a second coupling disk (9), the two coupling disks (8; 9) being arranged axially adjacent and each of the two coupling disks (8; 9) on the axial end face, which faces the other coupling disk (9; 8), has first form-locking means (10) for forming the freewheel and wherein the two coupling disks (8; 9) can be arranged axially displaceably relative to one another on an axis (11) shared with the stator (2). Furthermore, the first coupling disc (8) is coupled to the rotor (3) via second form-locking means (12) and the second coupling disc (9) is coupled to the drive disc (4) via third form-locking means (13), and is an actuator (14) present, via which the first coupling disc (8) and the second coupling disc (9) can be axially displaced against each other, in such a way that a power transmission via the first form-fitting means (10) of the coupling discs (8; 9) is canceled in both directions of rotation.
