Embodiment Construction

[0027] figure 1 with 2 The shift device 1 in the form of a shift mechanism box frame is shown. The shift mechanism box frame includes: a housing 2 that can be screwed to the transmission housing with an unshown housing part; a shift lever 3 configured as a shift shaft and rotatably supported in the housing 2; And two handles 4 for moving the shift lever 3.

[0028] The handle 4 is respectively constituted as a shift lever 5 and a shift lever 7, wherein by means of the shift lever, the sleeve 6 connected to the shift lever 3 in a non-rotatable manner can move in a translational manner. The handle causes the sleeve 6 to rotate. The shanks 4 are each constructed in multiple parts and each have a ball head 8 for their articulation via a cable drive. The rope transmission device is connected with the shift handle of the operator.

[0029] The shift lever 7 is provided with a shift block 9 on its radially outer end, which increases the moment of inertia of the shift device 1 in order ...

Abstract

The invention relates to a shifting device (1) of a motor vehicle speed-change gearbox having a shift rod (3), a pivotable lever (4, 5) which has an actuating element (15) by means of which the shift rod (3) or a shifting element disposed on the shift rod is translationally movable and a coupling element (16) which is disposed on the shift rod (3) so as to not move axially and on which the actuating element (15) engages. The invention is characterized in that in at least one rest position the actuating element (15) is spaced apart from the coupling element (16) or in that in at least one rest position the actuating element (15) and the coupling element (16) have a contact surface which is minimal with regard to the possible positions of the actuating element (15).

Description

Technical field [0001] The invention relates to a gear shifting device for a transmission of a motor vehicle, which has: a shift lever; a pivotable handle with a control element, via the control element, the shift lever or a gear shift arranged on the shift lever The element can move in translation; and a coupling element that is axially fixedly arranged on the shift lever, and the operating element is engaged with the coupling element. Background technique [0002] The shifting device of a gear transmission of a motor vehicle has a dynamic chain composed of individual structural elements or components in operative connection. The dynamic chain describes the connection between the operator shift lever operated by the driver and the gear shifted by the operation of the operator shift lever. In the chain, there are elements that transmit the shifting movement, such as a rope drive, a connecting rod, a shift shaft, and a shift fork shaft. The other components are the stop device, ...
