Example Embodiment

[0021] FIG. 1 illustrates a shift device 1 with a bundle of shift fork shafts 2, 3 and 4. Each shift fork shaft 2, 3, 4 has one of shift forks 6, 7 or 8 and a shift opening 9 as an operating member 5. The shift fork shafts 2, 3, 4 are slid or rolled longitudinally movably in the parallel Z longitudinal direction shown by the double arrow 14 in the bearing end covers 10 and 11 by means of the support 12 not described in detail.

[0022] The shift fork shafts 2 and 4 also each have at least one roller bearing 13. Roller bearing 13 in figure 2 The center is shown in cross-section and each consists of a pin 15 and a roller 16. The pin shaft 15 is fixedly held in the receiving place 17 of the respective shift fork shaft 2 or 4 and the shaft is used for a roller 16 rotatably supported on the pin shaft 15. The roller 16 can be rotatably slid or rolled on the pin 15 around the longitudinal center axis 18. It is also conceivable that instead of one roller, a plurality of rollers are suppo...

Abstract

The invention relates to a shift device (1) having at least two shift rails (2, 3, 4, 19, 20, 21) which are adjacent to one another at least in sections, wherein the shift rails (2, 3 ,4, 19, 20, 21) are mounted at the transmission side so as to be moveable relative to one another and independently of one another in parallel longitudinal directions.

Description

technical field [0001] The invention relates to a shifting device having at least two shift fork shafts which adjoin one another at least in sections, wherein the shift fork shafts are mounted displaceably opposite each other in parallel longitudinal directions and at the same time independently of each other. transmission side. Background technique [0002] The shift fork shaft is a shifting part that can mostly move along its main shaft, on which operating parts such as shift forks and levers are arranged and transmit operating force and torque for the shifting, selection, control and interlocking of the mechanism and transmission structural components and exercise. Most of these shifting elements are mounted at least longitudinally displaceably on the vehicle transmission at two bearing points. Shift fork shafts on modern automotive transmissions are usually stamped parts of sheet steel and have dimensions that narrow in one direction towards the thickness of the origin...
