Assembly of a switching device and process of making this assembly

摘要

The unit has a support (3) of an iron material to support a machine part (4) which is in the form of a roller (8). The machine part is connected to the support for the machine part that is to be pivotable about an axis of rotation of the machine part. A hard outer layer is produced in a thermochemical heat treatment of the complete modular unit. The roller is connected to the support by a bolt (5). An Independent claim is also included for a method of producing a modular unit for use in a gear shift mechanism.
