Embodiment Construction

[0017] FIG. 2 shows a shaft 2 manufactured by combining the non-cutting forming method and the cutting method. The bracket 3 in Fig. 3 is a stamping part. The mechanical element 4 in FIG. 4, which is formed as a roller 8, is produced without cutting by rolling or extrusion and is optionally cut in the cylindrical through-hole 8a. Figure 5 shows the bolt 5 as an extrusion. All parts of the listed assembly 1 are manufactured from low carbon case hardened steel (material designation eg 16MnCr5). Parts 2, 3, 4, 5 are assembled into composite part 1 in the following order:

[0018] - Join the shift lever 7 with the through hole 7a to the sliding seat 2a of the shaft 2 and reinforce it with a laser weld 9;

[0019] - position the roller 8 in the opening 2b and pass the bolt 5 into the through hole 8a;

[0020] - Press the bolt 5 into the circular through-hole 7b and fasten the bolt 5 on the bracket 3 by means of the laser weld 10 .

[0021] After assembly, the combined component ...

Abstract

A modular unit of a gear-shifting mechanism with individual assembled together components including a machine part and a support therefor, which are rotatable relatively. The unit is subjected after the assembly of the components to a complete heat treatment and optionally subsequently to a coating. The heat treatment may be thermochemical or nitriding and the coating layer may be iron oxide.

Description

technical field [0001] The invention relates to an assembly part of a shifting device and a method for producing the assembly part, wherein the assembly part is prefabricated independently of the shifting unit, and the assembly part comprises at least one ferrous mechanical element and at least one ferrous mechanical element supporting the mechanical element A bracket; wherein the mechanical element surrounding the rotation axis is at least swingably connected with the bracket relative to the bracket. Background technique [0002] Such composite components are, for example, shift shaft units or shift shaft units in automobile and motorcycle transmissions. The invention also relates to other composite components, wherein the composite components are preassembled before the transmission parts which are movable and connected to each other are installed in the vehicle transmission. In this respect, the combined part has at least one carrier, which is formed, for example, as a l...
