Getriebeaktor für ein Kraftfahrzeuggetriebe

摘要

The invention relates to a transmission actuator for a motor vehicle transmission device which has a plurality of transmission ratios for forming gears, wherein the transmission actuator has a shifting shaft which is mounted in a rotatable manner for shifting gears and is mounted in an axially displaceable manner for selecting gears, and wherein the transmission actuator has a gate having a first gate part which is arranged in a stationary manner and a second gate part which is rotatable and axially displaceable, wherein one gate part has grooves and lands alternating in one direction and the other gate part has at least one element that can cooperate with one land at a time and can be moved into one groove at a time; wherein the at least one element is moved past the lands and grooves during a selection movement in a defined direction and is moved into one of the grooves during a shifting movement; wherein a lead-in bevel is provided at least on the lands or on the element so that the movable gate part, in the event of a collision between the element and the land during a shifting movement, can continue to move over the lead-in bevel in the defined direction of the selection movement and the shifting movement can be continued; wherein substantially right-angled transitions are also provided so that, in the event of a collision between the element and the land during the shifting movement, the movable gate part cannot be moved counter to the selection movement but rather the shifting movement is stopped.
