The present disclosure relates to a switch module for a gearbox, in particular a motor vehicle gearbox, with a housing, a switching shaft and a control lever for moving the switching shaft relative to the housing. The housing has an interface for temporarily fastening an assembly device. The control lever has an interface for interacting with the assembly device fastened to the housing interface for limiting its actuating path.

A shift system for shifting a gear unit has at least one movably disposed selector shaft and at least one switch element. The selected position of the switch element is changed by movement of the selector shaft relative to the switch element. A drive shaft is rotatable about a centre axis. In a first selected position of the switch element, it can be connected to co-rotate at least in one direction of rotation to a component of the gear unit. In a second selected position of the switch element, it can be disconnectable from the component of the gear unit in each direction of rotation. At least a part of the switch element co-rotates with a rotation of the drive shaft about the centre axis, so that relative movement of the switch element with respect to the selector shaft is generated. A gear unit has such a switch system.

In a vehicle drive transmission device, a transmission includes an intermesh first engagement device, a frictional second engagement device, a first drive device configured to drive the first engagement device, and a second drive device configured to drive the second engagement device. The first drive device includes a first shift drum, a first cam mechanism configured to convert rotational motion of the first shift drum into linear motion, and a first transmission mechanism configured to perform the linear motion.
