The invention relates to a method for the manufacturing of a bearing element of a shift device for a motor vehicle transmission. In a first process step a bearing element is provided, which comprises at least one projection and a coupling joint for the mechanical coupling of a selector lever in order to select a shift position of a motor vehicle transmission. The projection is overmolded by means of an assembly injection molding process with a bearing bushing material in order to form a bearing bushing to mount the bearing element in a moveable manner.

A cable pull for transmitting a tensile and/or pressure force to a pivot point is presented. The cable pull has a counter bearing, a tie rod, an adjustment unit and a locking element. The counter bearing is designed to introduce a counter bearing into a casing of the cable pull, counter to the tensile and/or pressure force. The tie rod is axially supported in the counter bearing, and coupled to a wire core of the cable pull. The tie rod has a molded part on an end protruding out of the counter bearing, having a first component of a toothing. The adjustment element is designed to adjust a length of the cable pull between the counter bearing and the pivot point. The adjustment element has a guide for the molded part. The molded part can move axially in the guide, and is disposed such that it is guided transverse thereto. The locking element is designed to fix the molded part in place in the adjustment unit. The locking element is disposed in a recess in the adjustment unit oriented transverse to the guide, and can move between a locking position and an adjustment position. The locking element has a second component of the toothing, which is designed to engage in the first component in a form fitting manner when in the locking position, and to suppress the axial movement of the molded part in the guide.

A device for locking an operation element of an automatic transmission of a vehicle may comprise a rotationally mounted locking comb including a locking contour configured to be coupled with an operation element. The device may further comprise a locking element, where the locking element is configured to be arranged in a first position outside the locking contour to release the locking comb for a rotational movement to allow a shifting movement of the operation element. The locking element may be configured to be arranged in a second position in the locking contour to fix the locking comb for locking the operation element. The device may further comprise a rotationally mounted set ring with a control contour for guiding the locking element between the first position and the second position.

An actuator for selecting shift stages of a vehicle transmission comprises a lever housing, a selector lever, as well as a transfer device for transferring switching commands to the speed change gear. The actuator is characterized by am exchangeable module adapter which is arranged between the lever housing and the transfer device. The module adapter has the purpose of adapting the actuator in such a way that the ergonomic point of the actuator can be changed in vertical and/or horizontal direction and thus be adapted to different situations of assembly. The actuator can be adapted to be installed in different vehicle types primarily by selecting the appropriate module adapter and without requiring considerable structural changes.

The present disclosure provides a device for selecting a desired switch position out of a plurality of switch positions, and a switch position depends on a position of at least one locking bolt relative to a snap-in cam, with a support member for a control element. The support member is arranged below a user interface and rotatable around a shaft relative to the locking bolt. The snap-in cam is designed in the support member, and a Maltese cross transmission structure is formed in the support member. A drive device is in engagement with the Maltese cross transmission structure so as to rotate the support member with the snap-in cam around the shaft relative to the locking bolt depending on the desired switch position.

An activation device for selecting shift stages of a shift-by-wire vehicle transmission comprises a housing and an activation knob which can be moved in a translatory fashion and a latching device with a latching pin and latching contour as latching elements for generating latching forces and restoring forces. The activation device is defined by a latching gearwheel which is in engagement with a toothing arrangement on the activation knob. In this context, one of the two latching elements is connected to the latching gearwheel and in this way forms a rotatable latching element. The second latching element is directly or indirectly connected to the base housing and forms the fixed latching element.

An actuation device for selecting gear settings of a shift-by-wire gear shifting transmission comprises an actuation element, a mechanical transference for actuating the parking brake, and a coupling device disposed between the actuation element and the mechanical transference. An actuation of the transference occurs selectively by the actuation element only when the parking brake setting is selected or de-selected at the shift lever. It is possible, structurally as well as with respect to its installment, to simplify the transference mechanism necessary for the selective actuation of the transference means for the parking brake. Structural space and costs can be reduced, and the actuation device can be designed to be smooth and quiet.

An actuating device is provided that includes an actuating element () with at least three switching positions. The actuating device () can be deflected starting from its basic positions at least in one direction into an intermediate switching position for selecting an operating state of the technical system.

The undesired jumping of the actuating element over intermediate switching positions, during switching, is effectively prevented from occurring. An intuitively detectable tactile feedback of the switching state of the actuating element or of the state of the system is provided.
