An actuator for actuating a shift element in a transmission of a vehicle, particularly of a utility vehicle, includes a sensor device for detecting angular positions of a rotating component, for example, a shaft in an electric drive for a vehicle. The sensor device includes an annular encoder magnet fastened to a support pin supported on a front side of the rotating component so as to be fixed with respect to rotation relative to it such that the annular encoder magnet at least partially surrounds the support pin. The annular encode magnet is mounted on the support pin as a molded encoder magnet component.

A gearbox actuator unit () is configured to be arranged on a gearbox () and includes a housing (), a control device (), and an actuator (). The housing () is configured to attach to a gearbox housing () and to seal the gearbox housing (). The control device () is electrically connected to the actuator () and activates the actuator (). A pinon of the actuator () is configured to actuate a rack of a shift fork () of the gearbox () and can be connected to the shift fork () of the gearbox (). The control device () and the actuator () are arranged within the housing (), with the pinion extending through an opening of the housing. A gearbox () with a housing () having an opening () receives the actuator unit (), which closes and seals the opening ().

An actuating apparatus has a first and a second actuating element that delimit a pressure chamber. The actuating apparatus has a rotary decoupling bearing coupled via a compensation assembly to the second actuating element for joint movement along the spatial axis. The compensation assembly comprises a first ramp element which is supported axially on the second actuating element and is preloaded relative to the second actuating element by a first preloading apparatus for rotation about the spatial axis and a second ramp element coupled to the rotary decoupling bearing. An axial overall length of the compensation group along the spatial axis changes in the case of a rotation, of the first ramp element relative to the second actuating element. The compensation assembly has a blocking element and a blocking toothing system in blocking engagement with a counter-blocking toothing system of the first ramp element

An actuating device for a motor vehicle, including a housing and a multi-part working piston movable in relation to the housing. The multi-part working piston has a main piston and an adjusting piston, which pistons are formed in a manner movable axially with respect to each other to compensate for wear. A clamping device clamps the main piston and the adjusting piston in relation to each other in order to fix an operative length of the working piston. The main piston and the adjusting piston are partial pistons of the working piston. A shielding element for protecting the actuating device from dirt is arranged on the housing and a partial piston or on a first partial piston and a second partial piston or on an adjusting piston and on the clamping device.
