Embodiment Construction

[0036] figure 1 A shift fork 1 according to the invention is shown with a partially shown shift fork shaft 2 . The shift fork 1 has a fork body 6 and a fork-shaped slide 7 . The fork body 6 is divided into two outer legs 8 and 9 . The fork-like carriage 7 is divided into two inner legs 10 and 11 . Outer legs 8 and 9 and inner legs 10 and 11 are integrally formed by plastic. This means that they are extruded from the extruder in one step. Furthermore, the details of the outer legs 8 and 9 and the inner legs 10 and 11 are described in detail in subsequent figures.

[0037] The fork body 6 includes a bush-shaped shift fork socket 4 . On the side facing the shift fork shaft 2 , the selector fork socket 4 is equipped with a bearing 5 , via which bearing the selector fork socket 4 accommodates the shift fork shaft 2 .

[0038] Furthermore, the shift fork socket 4 includes the shift arm 3 . The selector arm 3 is U-shaped and accordingly includes two webs 12.1 and 12.2. The tw...

Abstract

The invention relates to the use of a fiber composite material to produce a shift fork (1), characterized by the following steps: a fiber, a laid fabric composed of fibers, or a woven fabric composedof fibers is inserted as a supporting structure into a negative injection mold in the shape of the shift fork (1); plastic is injected and / or pressed into the negative injection mold; the supporting structure is overmolded with plastic, wherein the plastic is a matrix for the fiber, the laid fabric, or the woven fabric.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 , a selector fork according to claim 7 and a use according to claim 9 . Background technique [0002] Various different types of shift forks are known and common in the prior art. [0003] Shift forks known from the prior art are made of sheet metal, wire or cast material. The disadvantage is that metal shift forks have a high dead weight and are expensive to manufacture. Contents of the invention [0004] The object of the present invention is to overcome the disadvantages of the prior art and to propose a method for producing a shift fork which enables the production of a low-weight shift fork with sufficient stability and at low cost. [0005] To achieve the above object, the present invention proposes the characterizing part of claim 1 . [0006] The invention relates to the use of fiber composite materials for the production of shift forks. [0007] Fiber composites are d...
