Embodiment Construction

[0027] figure 1 with 2 The shifting device 1 is shown in the form of a shifting housing. The gearshift housing comprises: a housing 2 , which can be screwed with a housing part not shown to the transmission housing; a selector lever 3 which is formed as a gearshift shaft and is rotatably mounted in the housing 2 ; And two handles 4 for moving the selector lever 3 .

[0028] The levers 4 are each formed as a selector lever 5 and as a selector lever 7 , by means of which a sleeve 6 connected in a rotationally fixed manner to the selector lever 3 can be moved in translation, the selector lever 3 The handle causes the casing 6 to rotate. The handles 4 are each constructed in multiple parts and each have a ball head 8 for their articulation via a cable drive. The cable drive is connected to the operator's shift lever.

[0029] On its radially outer end, the selector knob 7 is provided with selector blocks 9 , which increase the moment of inertia of the selector device 1 in ord...

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 shifting device for a motor vehicle transmission, comprising: a selector lever; a pivotable handle with an actuating element, via which the selector lever or a selector arranged on the selector lever an element displaceable in translation; and a coupling element arranged axially fixed on the selector lever, on which the actuating element engages. Background technique [0002] The shifting device of a motor vehicle gear transmission has a kinematic chain of individually operatively connected structural elements or assemblies. The dynamic chain describes the connection between the operator's selector lever actuated by the driver and the gearwheels shifted by the operator's actuation of the selector lever. In the chain there are elements which transmit the shifting movement, such as cable drives, connecting rods, shifting shafts and shifting fork shafts. The other elements are the stop device, the locking mechanism and the sli...
