A transmission actuator has gear steps for forming gears and a selector shaft supported rotatably for shifting gears and supported axially movably for selecting gears. The actuator has a gate with a fixed first gate part and an axially movable and rotatable second gate part, the one gate part having slots and lands alternating in a direction and the other gate part having at least one element which can interact with one of the lands at a time and is movable into one of the slots at a time. The element is moved in a prescribed direction past the lands and slots in a selecting motion and is moved into one of the slots in a shifting motion. When there is a collision between element and land during a shifting motion the movable gate part can be moved further in the prescribed direction of the selecting motion by an insertion chamfer and when there is a the movable gate part is not movable contrary to the prescribed direction of the selecting motion, but the shifting motion is stopped.

This vehicle transmission device includes the shift block for a reverse-1st speed, a 4th speed-5th speed, a 2nd speed-3rd speed, and a 6th speed arranged in this order in a selection operation direction. The vehicle transmission device also includes first through fourth shift levers that engage respectively with the shift blocks, a first select actuator that moves the first or second shift lever for a select operation, a first shift actuator that moves the first or second shift lever for a shift operation, a second select actuator that moves the third or fourth shift lever for the select operation, and a second shift actuator that moves the third or fourth shift lever for the shift operation.

An electric drive for a vehicle includes at least one electric machine (1) with a rotor shaft (2) as a drive shaft, a transmission connected to a first output shaft (3) and a second output shaft (4), and a shift element (5) with at least one actuatable coupling element for achieving a first shift position (N), a second shift position (S2) and a third shift position (S2). In the first shift position (N), the coupling element is connected either to an element of the transmission or to the rotor shaft (2). In the second shift position (S1), the element of the transmission is connected to the rotor shaft (2) via the coupling element. In the third shift position (S2), the element of the transmission and the rotor shaft (2) are connected to the housing via the coupling element.
