Embodiment Construction

[0024] figure 1 The shifting device 1 shown in is a component of a shift transmission of a motor vehicle. The shifting device 1 comprises a selector lever 2 which is connected in a rotationally fixed manner to a selector shaft 3 . figure 1 shows that the selector lever 2 is arranged approximately perpendicularly to the selector shaft 3 , so that torque can be introduced via the selector lever 2 , which has on its underside a figure 1 Ball pins covered in view of . Due to the applied torque, the selector shaft 3 is rotated about its longitudinal axis. exist figure 1 A rope is fixed on the covered ball pin, and the rope is connected with the manual shift lever of the motor vehicle.

[0025] The selector lever 2 has a damper 4 with a shift weight 5 . The damper 4 damps hard end impacts which can occur during a shifting operation. The damper 4 is designed such that the transmission of vibrations or oscillations from the transmission via the shifting device 1 to the manual se...

Abstract

The invention relates to a switchgear (1) for a transmission of a motor vehicle, having a switching shaft (3), which is movable along the longitudinal axis thereof in a selection direction and rotatable by means of a shift lever (2) around a longitudinal axis thereof in a shifting direction, wherein the switching shaft (3) is designed divided in the longitudinal direction and has a primary shaft (11), permanently connected to the shift lever (2), and a secondary shaft (12), permanently connected to at least one shifting sleeve (9) and / or to at least one locking sleeve, wherein the primary sleeve (11) and secondary shaft (12) are connected to each other such that there is play enabling a rotation around the longitudinal axis.

Description

technical field [0001] The invention relates to a shifting device for a shifting transmission of a motor vehicle, which has a shifting shaft which is displaceable along its longitudinal axis in a selection direction and which is displaceable by means of a shifting shaft. The gear lever rotates about the longitudinal axis of the gearshift shaft in the gearshift direction. Background technique [0002] Such a shifting device is known from DE 10 2011 007 251 A1. The shifting device includes a shifting shaft which can be moved axially by means of a selector lever. In this way, a specific shift gate in the transmission is selected. In addition, a pivotable selector lever is provided in order to rotate the selector shaft, thereby engaging or shifting a gear of the selector transmission. These two levers are respectively connected with a manual shift lever in the interior of the vehicle via a cable or a link. [0003] Furthermore, modified shifting devices are known in which th...
