Problems solved by technology

[0006]However, these M-profiles are not suitable for sensing for shift position detection because the surface structure means that due to the "neutral" and "engaged "gear position" overlap height of the shift position, it is not possible to obtain an unambiguous coding

Embodiment Construction

[0055] figure 1 A schematic diagram showing the structure of the locking device R1 according to the present invention. The shifting profile of the locking device R1 is formed by two partial shifting profiles, the neutral locking profile 1 and the gear locking profile 2 . These profiles are arranged opposite each other on the circumference 20 . The sub-shift profiles are operatively connected to one another in such a way that they perform a joint movement. The neutral locking profile 1 is equipped with a first locking part 3 . Similarly, the gear locking profile 2 is provided with a second locking part 4 . The first locking part 3 includes a ball 11 , and the ball 11 is subjected to the elastic force of the elastic part 9 . The neutral locking profile 1 has a groove 12 occupied by a ball 11 . When the ball 11 is in the groove 12, the transmission is in neutral position. In the shifting direction, the neutral lock contour 1 ends at a constant radius Ra. In contrast, the ...

Abstract

The invention relates to a locking device (R1, R2), particularly for a gear shift lever shaft (5) of a manual transmission, having a shift contour, which is operatively connected to a first stop element (3, 3.1). The shift contour is configured to be operatively connected to a second stop element (4, 4.1), wherein the first stop element (3, 3.1) has a dedicated measuring element (13).

Description

technical field [0001] The invention relates to a locking device for a shift lever shaft of a manual transmission, the device having a shifting profile operatively connected to a first locking member. [0002] Background technique [0003] Lockout devices are used in manual transmissions to provide non-rigid hold of the "neutral" and "engaged" shift positions. [0004] For this purpose, conventional systems have a so-called M-profile, which provides a double retaining function by means of a locking part subjected to elastic force. [0005] To return the selector lever shaft to its original position in the neutral, preferably 3rd / 4th gear shifting gate, either on the one hand with an elastic system or, on the other hand with a ramp profile, by means of locking elements subjected to elastic forces, This creates resilience. These ramp profiles are implemented as separate profiles or in combination with M profiles. [0006] However, this surface structure, including the small...
