Hollow shaft i.e. motor shaft, for transmitting power within electric power steering system in vehicle, has different regions with surface structures and/or different outer and inner diameters, where regions are formed by rotary swaging

摘要

The shaft (503) has different regions (501, 505, 507) with different surface structures and/or different outer diameters (509) and different inner diameters and formed by rotary swaging. The regions are formed as a machine element that is selected from tooth wheel or belt pulley. The regions include a slot and/or a notch and/or gear teeth formed by the rotary swaging. The regions are provided with grooves, projection or a surface structure for form-fitting connection with the machine element that is designed as a rotor packet of an electric servo-motor. An independent claim is also included for a method for manufacturing a hollow shaft for transmitting power within an electric power steering system.
