Embodiment Construction

[0024] figure 1 The shifting device 1 is shown with a shift fork 5 and a shift shaft 2 on which a component 7 in the form of a bushing 8 is arranged in a rotationally fixed manner. The bushing 8 has a shifting finger 4 as shifting element 3 , which engages in a shift opening 6 of a shifting fork 5 . The shift opening 6 is designed as a punched recess in the shift arm 14 . The selector arm 14 is connected to the base body 10 and forms the selector fork 5 together with this base body and the guide tube 9 .

[0025] according to figure 1 shows the shifting device 1 in the neutral state, wherein, via the preselection gate, the shifting finger 4 is positioned in the axial direction of the shifting shaft 2 such that it lies in the plane of the shifting arm 14 middle. In this state, the selector finger is surrounded laterally in the shifting direction by the mouth walls 17, 18, but at the same time is spaced apart by a gap 19 or 20, so that vibrations are not induced due to the g...

Abstract

The invention relates to a shift arrangement (1) for a gear-change transmission, which arrangement has: a selector shaft (2) comprising a shift element (3); and a gearshift fork (5) with selector jaws (6). The shift element (3) can be brought into engagement in a guide channel (16) in the selector jaws (6) such that the gearshift fork (5) can be moved as a result of rotation of the selector shaft (2), the guide channel (16) having in the direction of the selector shaft (2) a constriction (Z) of which the diameter is smaller than that of the shift element (3).

Description

technical field [0001] The invention relates to a shifting device of a gear transmission having a shifting shaft with a shifting element and a shift fork with a shifting opening, wherein the shifting element can engage in a guide channel of the shifting opening , so that the shift fork can be moved by twisting the shift shaft. Background technique [0002] Shifting devices, especially for gear transmissions, usually have a selector fork, which is connected to a selector lever. The shift fork usually engages positively in a sliding sleeve of the synchronizer, by means of which the idler gear is coupled to the main or countershaft via a coupling element. The selector fork is usually rigidly connected to the selector lever. As an alternative to this, however, a selector fork inserted as a selector rocker is arranged axially displaceable and / or rotatably relative to the selector lever. The selector fork is then actuated by means of a selector finger arranged on the selector s...
