A device (5) for selective displacement of a shift element (4) towards a first shift position and/or a second shift position includes an actuator (6) and a spring module (7). The spring module (7) includes an actuator-side force-introduction element, a shift element-side force-introduction element, and a spring arrangement. The spring arrangement includes a first spring end and a second spring end. The actuator-side force-introduction element and the shift element-side force-introduction element each include a first support section and a second support section for supporting the spring ends. The first spring end is associated with the first support section of the shift element-side force-introduction element and with the second support section of the actuator-side force-introduction element. The second spring end is associated with the first support section of the actuator-side force-introduction element and with the second support section of the shift element-side force-introduction element.

Systems are provided for a gear set housing. In one example, a system comprises a gear box housing configured to house a four stage gear set in combination with a shift actuator and a differential lock, wherein the four stage gear set comprises an input shaft, a first layshaft, a second layshaft, and an output shaft.

An actuator for a transmission may include a shift fork coupled to a sleeve; a ball screw mounted to pass through a portion of the shift fork; and at least a guide shaft mounted to pass through a portion of the shift fork to be parallel to the ball screw.

A shifting actuator for a transmission including a ball screw drive, having an electric-motor-driven threaded spindle, a multi-part spindle nut, and rolling elements, namely balls, which roll between the threaded spindle and the spindle nut. The nut body has a ball groove, in which there roll balls that are also in contact with the threaded spindle, and is within the sleeve. The shift fork protrudes from the sleeve and is fixed relative to the sleeve and to the main nut body.

The invention relates to a shifting device for the selection of rotationally fixed non-rotational couplings of a plurality of coaxial shafts of a motor-vehicle transmission, comprising a displacement sleeve, which can be axially displaced in relation to a housing and which has internal teeth having two axial toothed sections spaced apart from each other by an axial gap, and which coaxially surrounds a plurality of toothed elements that are arranged axially adjacent to each other and that are each non-rotationally connected to one of the shafts and that each have external teeth corresponding to the internal teeth of the displacement sleeve, wherein the displacement sleeve has a first sleeve part and a second sleeve part that are connected to each other in a manner that is axially fixed and rotationally decoupled, wherein the first sleeve part is a carrier of the first axial toothed section and the second sleeve part is a carrier of the second axial toothed section.

An actuator assembly that includes a frame, an output member, a latch and a spring. The output member is movable along an axis relative to the frame between a first position and a second position. The latch has a first latch member, which is movable along the axis, and a second latch member that is coupled to the output member. The second latch member is configured to engage the first latch member to retain the actuator output member in the first position. The spring exerts a force on the actuator output member when the second latch member engages the first latch member to retain the actuator output member in the first position. The force is configured to urge the actuator output member toward the second position when the second latch member is disengaged from the first latch member.

An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator (1) and a rotor (2). The electro-mechanical actuator also includes a spindle drive with a rotary element (6) and with an element that is movable in a translatory manner. A rotation of the rotary element (6) may result in a translatory motion of the element that is movable in a translatory manner. The rotor (2) and the rotary element (6) of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor (2) results in a rotation of the rotary element (6) of the spindle drive (5). A rotational play (8) is formed between the rotor (2) and the rotary element (6) of the spindle drive in the circumferential direction (U).

A parking lock for motor vehicle, including a parking lock wheel that can be connected to a shaft of the motor vehicle in a rotationally fixed manner, at least one blocking element, and an actuator, by which the blocking element is movable between at least one blocking position securing the parking lock wheel against rotation, and at least one release position releasing the parking lock wheel for a rotation, comprising at least one spring element, which by the actuator is to be tensioned during the moving of the blocking element into the blocking position, thus providing a spring force in the blocking position of the blocking element, by which the actuator is to be supported during the movement of the blocking element into the release position.

An actuator module for a driveline assembly includes, among other things, a cover housing and a fork driving unit supported by the cover housing. The fork driving unit includes a fork driver and a pusher assembly coupled to the fork driver by spaced apart pusher ends. The fork driving unit also includes a drive assembly carried by the pusher assembly to translate the fork driver relative to the cover housing. The fork driving unit further includes a spring that biases the pusher assembly and fork driver to a neutral position.

The disclosure relates to an actuator arrangement for operating a clutch and a parking lock in a driveline of a motor vehicle, comprising: a clutch having a clutch actuating member configured to drivingly connect or disconnect a clutch input part and a clutch output part; a parking lock having a locking element movable to a locking position to lock a ratchet wheel, and to a release position to release the ratchet wheel; and a parking lock actuating member for actuating the locking element; a controllable actuator with a movable actuator setting member which is movable into at least three setting positions and is operatively connected to the clutch actuating member and to the parking lock actuating member such that in a first setting position the parking lock is closed, in a second setting position the clutch is closed, and in a third setting position the clutch and the parking lock are opened.
