Problems solved by technology

However, it has the disadvantage that the drive elements are spaced far apart, which is a perceived disadvantage when making gear selections (changing channels)
[0011] Another disadvantage of the known shifting device is that the transmission of the shifting movement by the sliding gears in the reverse shifting can only be carried out by an expensive mechanism comprising several parts

Embodiment Construction

[0074] In FIG. 1 , a first embodiment of the shifting device according to the invention is indicated with 10 .

[0075] The shifting device 10 is used to engage the gears of a motor vehicle transmission, in particular a manual transmission of conventional type (for example an intermediate transmission type).

[0076] More specifically, shifter 10 is used to engage and disengage forward gears 1 to 5 which are engaged and disengaged by movement of corresponding shift sleeves on the transmission shaft. The shifting device 10 is also used to engage the reverse gear of the transmission, which is engaged and released by movement of the sliding meshing gear.

[0077] The shifting device 10 has a selector lever shaft 12 which rotates for shifting gears, that is to say for engaging and releasing gears, as indicated by arrow 14 . To select a gear or channel, the selector shaft 12 is moved longitudinally, as indicated by arrow 16 in FIG. 1 .

[0078] In a typical application, the shift...

Abstract

The invention relates to a gear-shifting device (10) for selecting and shifting gear steps (1-5, R) of a gearbox (58), especially for motor vehicles. Said device comprises a plurality of gear-shifting elements (20A, 20B, 20C) that are displaceably mounted in such a way as to actuate associated sliding sleeves (52) in the axial direction (30) and respectively comprise a driving element (48); a rotatably and displaceably mounted gear-shifting shaft (12) comprising a shift finger (50) that selectively comes into contact with a driving element (48) in order to drive the respective gear-shifting element (20) during a movement of the gear-shifting shaft (12); and a shifting gate (70). At least two gear-shifting elements (20) are guided reciprocally in the axial direction, and the gear-shifting elements (20) are guided into the shifting gate (70) as a packet (92).

Description

technical field [0001] The invention relates to a shifting device for selecting and shifting gears, in particular of a gearbox of a motor vehicle, comprising: a plurality of shifting elements mounted in such a movable manner to move along a shaft To actuate the associated shift sleeve, and each shift element has a drive element; a rotatably and movably mounted shift lever shaft, which has a shift selectively acting on one drive element at a time fingers, to actuate the corresponding shift element when the shift lever shaft is moved; and the shift positioning plate. Background technique [0002] Such a shifting device is known from EP 0 893 628 A1. [0003] Such a shifting device is particularly suitable for manual transmissions, but in principle is also suitable for automatic manual transmissions, dual clutch transmissions and the like. [0004] The shift element can take the form of, for example, a shift fork or a shift rocker. [0005] Shift positioning plates or shift ...
