Actuator for a motorcycle transmission for changing from a first shifting stage into at least one further shifting stage, having a shifting drum (1) which is mounted rotatably about a shifting axis (1a) and on which at least one actuation region (1b) is arranged, a motorized shifting drive (4) which is set up to provide a shifting rotational movement for the shifting drum (1), an actuator transmission (2) for driving the shifting drum (1) with a drive member (2b) and an output member (2a) which are mounted as transmission members (2a, 2b) rotatably about in each case one transmission axis (2c, 2d), wherein the actuator has a first operating state, in which the shifting drive (4) sets the drive member (2b) in a rotational movement about the drive axis (2d) and a drive region which is arranged on the drive member (2b) makes contact with the output member (2a) in such a way that the latter is set in a rotational movement about the output axis (2c), characterized in that one of the transmission members (2a, 2b) has a blocking region, in that, in a second operating state, the shifting drive (4) sets the drive member (2b) in a rotational movement about the drive axis (2d) and the transmission members (2a, 2b) make contact in the blocking region at at least one contact point (5a), and in that, at said contact point (5a), the surface of the output member (2a) has a tangential profile with respect to the movement direction (6a) of the contact point (5a) on the drive member (2b), with the result that the output member (2a) is not set in a rotational movement by the drive member (2b) in the second operating mode. |
