Problems solved by technology

However, in the event of an overload, for example due to an unsuitable shifting movement, in particular as in the case according to DE 199 54 545 C1, the distance between the bearing points of the shift fork shaft and the cross-section of the shift fork shaft If the ratio is relatively large, there is a danger of twisting or longitudinal bending of the selector fork shaft

Embodiment Construction

[0021] FIG. 1 shows a diagram of a shifting device 1 with a bundle of shift fork shafts 2 , 3 and 4 . Each shift fork shaft 2 , 3 , 4 has one of the shift forks 6 , 7 or 8 and a shift opening 9 as actuating part 5 . The shift fork shafts 2 , 3 , 4 are mounted longitudinally displaceably in the bearing end shields 10 and 11 by means of bearings 12 , not described in detail, in a parallel Z longitudinal direction indicated by double arrow 14 .

[0022] The shift fork shafts 2 and 4 also each have at least one roller bearing 13 . Roller bearings 13 in figure 2 are shown in section and each consist of a pin 15 and a roller 16 . The pin 15 is held stationary in a receptacle 17 of the respective shift fork shaft 2 or 4 and serves as a shaft for a roller 16 which is rotatably mounted on the pin 15 . The roller 16 is rotatably sliding or rolling mounted on the pin 15 about the longitudinal center axis 18 . It is also conceivable to mount a plurality of rollers on pins instead of o...

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...
