Problems solved by technology

But this requires a complex structure both in the slider and in the base
But this increases the manufacturing cost, wherein, especially when the shift fork is manufactured in large quantities, the cost of a small increase cannot be ignored

Embodiment Construction

[0037] figure 1 The shift fork 100 of the first embodiment is shown.

[0038] The shift fork 100 in the illustrated embodiment comprises a base body 10 and two slides 20 which are arranged opposite each other on the ends of the fork-shaped base body 10 .

[0039] figure 2 Each 3 shows an enlarged view of the slide 20 and the fork-shaped base body 10 for receiving the end of the respective slide 20 in the first embodiment. Figures 6a-6c The different views show the shift fork according to the first embodiment of the invention in engagement with the sliding sleeve 110 . figure 2 , 3 Intersect with 6a-6c below for introduction.

[0040] The slider 20 in the first embodiment has a U-shaped cross-section comprising two arms 26 . Each arm 26 includes a centrally formed arcuate segment 24 within each arm 26 . Each side of each arcuate segment 24 forms a hole 22 respectively.

[0041] The arcuate section 24 of each arm 26 of each slide 20 is formed correspondingly to the sha...

Abstract

The invention relates to a shift fork (100) of a vehicle transmission, having a basic body (10) which is of fork-shaped design and having at least one sliding shoe (20) which is bent over the basic body (10) in a respective bending direction (S) and which is connected in a positively-locking manner to the basic body (10), and is characterized in that the basic body (10) has at least one fixing element for each sliding shoe (20) and the at least one sliding shoe (20) has in each case one complementary element in order to fix the at least one sliding shoe (20) perpendicular to the bending direction (S). The invention also relates to a method for producing a shift fork.

Description

technical field [0001] The invention relates to a shift fork of an automobile transmission, which has a fork-shaped base body and at least one sliding block, which is stretched back on the base body along respective stretching directions and is positively connected to the base body. The invention also relates to a method for producing a shift fork. Background technique [0002] Shift forks are known in the prior art. For example, document DE19944323A1 describes a shift fork. In this respect, the free end of the fork-shaped plate-shaped part has a slide. Such a shift fork is produced as far as possible without the use of machining operations, for example by deforming sheet metal by stamping, drawing or pressing or by a combination of these methods. The shift fork is therefore cost-effectively produced from sheet metal, in particular mass-produced, and is used more and more frequently. Further steel structural parts can be attached to the steel plate in a simple manner by ...
