A transmission shift device is provided that includes, but is not limited to a shifting shaft, which is mounted so it is axially immovable and rotatable in a transmission shift housing and is mechanically connected to a shift lever. Furthermore, the transmission shift device includes, but is not limited to a selector lever, which is mounted so it is axially displaceable on the shifting shaft and is mechanically connected to a selector lever. The selector lever is held in a spring-elastic manner in a middle axial selection position on the shifting shaft by at least one spring element.

Transmission shift device

A gear shift lever is provided with damping device of a vehicle. The damping device damps the returning of a reverse gear blocking element in the axial direction of the gear shift lever into a blocking position. For this, the damping device has a first rigid ring element in the axial direction of the gear shift lever, which surrounds the gear shift lever and has projections distributed on the periphery in axial direction. In addition, the damping device has a second rigid ring element, which has recesses in the region of the projections of the first ring element. On the reverse gear blocking element and on the gear shift lever, radial shoulders are arranged, against which the two rigid ring elements support themselves axially. Between the first and the second rigid ring element a rubber-elastic ring element is arranged which is deformable in a rubber-elastic manner between the projections of the first rigid ring element and the recesses of the second rigid ring element on the returning of a reverse gear blocking element.

Gear shift lever with damping device of a vehicle

A setting device for aligning a shift transmission, including, but not limited to a main bearing shaft mounted in a shift lever housing and a setting element, which can be hooked in guide means mounted on the shift lever housing, the setting element being situated along a central axis of the main bearing shaft.

Setting device for aligning a shift transmission

A gearshift device for a change-speed gearbox of a motor vehicle, includes, but is not limited to a gearshift lever guided movably between positions corresponding to different gears, on which a locking member is displaceable between a locking position in a first degree of freedom in which it blocks any movement of the gearshift lever from a forward gear position into a reverse gear position, and a release position in a first degree of freedom in which it allows movement from the forward gear position into the reverse gear position. The locking member on the gearshift lever is movable in a second degree of freedom between a normal position in which movement between release position and locking position is possible and an alignment position in which it fixes the gearshift lever free from play.
