Problems solved by technology

[0003] The problem that arises especially when changing gears manually is that, by mistake, one of the two gear positions of the desired selector slide is not engaged, but "diagonally shifted", thereby switching between the other selector slides. one gear
This "mismatching" leads to the insertion of wrong gears, so that, in the worst case, the speed and direction of rotation of the transmission and drive motor do not match and undesired driving situations can occur, or even damage to the transmission or drive motor

Embodiment Construction

[0030] Identical or mutually corresponding components are denoted by identical or corresponding reference numerals in the figures.

[0031] figure 1 A schematic three-dimensional illustration of a detail of a shifting device 1 with a locking device is shown. The shifting device 1 comprises a shifting shaft 2 , which is functionally connected at its free end to a manual shift lever actuatable by the driver. The shifting shaft 2 is arranged displaceably in the direction of its axial extent along the arrow 3 and is also pivotable about its own axis in the direction of rotation according to the arrow 4 . as in particular from the combination figure 2 and 3 It is known from the overview that the shifting device 1 comprises a shifting sleeve 5, which is arranged coaxially with the shifting shaft 2 and is non-displaceable and relatively non-rotatable with the shifting shaft, for example, in a material fit, especially through Solder to connect. The selector sleeve 5 carries on i...

Abstract

The invention is based on the aim of providing a shifting device having a locking device for locking shifting rails for a transmission of motor vehicles, the device being safe to operate and cost-effective. The invention provides a shifting device (1) for a transmission of a motor vehicle having a locking device (11), comprising a selector shaft (2) for the preselection and shifting of gears in the transmission, and having a plurality of shifting rails (9) a, b, c, d for transmitting the shifting torques from the selector shaft (2) to the transmission, wherein the selector shaft (2) is aligned perpendicular to the shifting rails (9) a, b, c, d, and is axially (3) displaceable for the preselection of gears and is disposed pivotally (4) about the own axis thereof for shifting gears, whereinthe locking device (11) has a locking section (12) for releasing one of the shifting rails (9) a, b, c, d and for locking the other shifting rails and a guide section (15) for axially guiding the locking device (11) to a guide member fixed on the housing, wherein the locking device (11) is configured and / or disposed such that it is carried along upon an axial displacement (3) of the selector shaft (2) for the preselection of the gears, and runs freely upon a pivoting (4) of the selector shaft for shifting the gears, wherein the locking section (12) is configured as a first planar sheet metal section defining a locking plane in the planar extension, and wherein a guide plane is defined as a displacement plane between the guide section (15) and the guide member, wherein the locking plane and the guide plane are arranged parallel to each other on the same side of the selector shaft (2).

Description

technical field [0001] The invention relates to a shifting device for a motor vehicle transmission, the shifting device having a locking device, a shift shaft for preselecting and switching gears in the transmission, a plurality of shift shafts for transmitting the shift torque from the shift shaft To the selector slide of the transmission, wherein the selector shaft is oriented perpendicularly to the selector slide and is arranged axially displaceable for preselecting a gear and swivelable about its own axis for shifting gears, wherein the locking device has a locking section and a guide section, a locking section for releasing one of the selector slides and locking the other selector slide, a guide section for axially guiding the locking device on a guide mechanism fixed relative to the housing, In this case, the locking device is designed and / or arranged in such a way that it moves together when the selector shaft is axially displaced for preselecting a gear, and when the s...
