Torsion module for torque detection device of e.g. steering system of motor vehicle, has spring elements forming radially extending bending spokes that are integrally connected with each other by connecting sections

摘要

The module has a spoked wheel (1) comprising an inner ring (2) fastened to a steering shaft and an outer ring (4) concentrically arranged to the inner ring. Two radially extending bending spokes (9) are arranged between the rings and connected with the rings in a form-fit manner. Spring elements (3) form the bending spokes that are integrally connected with each other by connecting sections. The connecting sections are inserted into the inner ring, where one of the connecting sections is formed as a circular arc section. The rings are formed as an injection molded plastic part.
