A cam mechanism for actuating a selector shaft, in particular for a single-motor gearshift actuation device, in particular to carry out a selecting movement of the selector shaft, comprising a cylindrical outer body having an inner circumferential surface and a cam track disposed on the inner circumferential surface and having an endless periodicity in a circumferential direction with at least one highest point and at least one lowest point, an inner body having at least one sliding guide extending in a direction perpendicular to the circumferential direction, at least one guide element disposed in the cam track and in the sliding and suitable for transmitting a movement of the guide element in a direction perpendicular to the circumferential direction to a selector shaft.

The invention relates to a gear actuator for a motor vehicle transmission design, that has several ratio steps for forming gears, whereby the gear actuator has a gear-shift shaft that is mounted so that it can rotate for the shifting of gears and that is mounted so that it can slide axially for the selection of gears and whereby the gear actuator also has a shift gate, whereby the shift gate also has a fixed mounted first shift gate part that is especially a shaft or an axle, as well as a second shift gate part that is mounted so that it can move axially and move in rotation or swivel, which is especially a disk or plate and is coupled with the gear-shift shaft and whereby the first shift gate part has several axially spaced recesses, into which the second shift gate part can be swiveled depending on its axial position.

A transmission system including a shift mechanism for operating and controlling the transmission system. To automatically detect geometric characteristic values of the transmission system or of the shifting device a selector motor and a shift motor actuate a select or finger that is displaceably mounted in a selection-shift-passageway layout. Starting from an initial position whose coordinates within the selection-shift-passageway layout are unknown, the selector finger is displaced in the directions of shifting and in the directions of selection in order to detect paths of movement in the direction of selection or shifting. The selector finger is repeatedly displaced to establish the maximum paths of movement until the predetermined transmission geometric characteristic values are completely detected. Also disclosed are a control device for controlling a transmission system that includes a shift mechanism, and a method for controlling such a transmission system.

The invention relates to a motor vehicle having a power train wherein the engine can drive an automatic transmission by way of an automatic clutch. The gear ratio of the transmission is selectable by a first drive and a second drive is employed to shift the transmission into the selected gear. The two drives are mounted on the transmission case by way of a common base plate. Novel kinematic transmission lines connect the drives to the ratio selecting and gear shifting components of the transmission. One of the transmission lines employs a transmission stage, a carrier for translation of rotary movement into axial movement, and an element for transfer of axial movement to the transmission. The translation of movement of the drive in a selection process takes place by way of two transmission stages.
