Actuator arrangement and shift-clutch arrangement

An actuator arrangement for the axial displacement of an actuation member by means of a drive force which is generated by an electric machine, the actuation member being mounted axially displaceably on a rotary shaft, the electric machine having a stator fixed to a housing and a rotor which is coupled to the actuation member and is arranged coaxially with respect to the actuation member,

• wherein the rotor is coupled to the actuation member via a rotation/translation converter, in such a way that, during rotation in relation to the rotor, the actuation member is displaced in the axial direction.

An actuator arrangement having an electric machine which comprises a stator and a rotor, the stator and the rotor being arranged coaxially with respect to the rotary shaft, wherein the rotor is coupled to an actuation member, and wherein the stator is interrupted in the circumferential direction in order to provide construction space for adjacent components in the radial direction.

A shift-clutch arrangement for a multi-step gear change transmission, with a guide sleeve which is secured to a rotary shaft and has a guide-sleeve toothing, with a shift sleeve having a shift-sleeve toothing which is in engagement with the guide-sleeve toothing, so that the shift sleeve is mounted fixedly in terms of rotation and axially displaceably with respect to the rotary shaft, and with a clutch body which is secured to a loose wheel mounted rotatably on the rotary shaft and which has a clutch-body toothing, into which the shift-sleeve toothing can be pushed in order to connect the loose wheel fixedly in terms of rotation to the rotary shaft,

• wherein the shift sleeve is axially displaceable by means of an actuator arrangement for the axial displacement of an actuation member by means of a drive force which is generated by an electric machine, the actuation member being mounted axially displaceably on a rotary shaft, the electric machine having a stator fixed to a housing and a rotor which is coupled to the actuation member and is arranged coaxially with respect to the actuation member, and the rotor being coupled to the actuation member with a form fit in the axial direction,
• wherein the rotor or the actuation member has a radial projection which engages into a radial groove of the other part.
