Abstract
A method for the production of a steering spindle part is provided. The method includes forming a section of a steering spindle for a motor vehicle and which is implemented in the form of a hollow shaft and includes at least a connection section adjoining one of its ends. The connection section has at least over a portion of its length a wall thickness (D) which, compared to a section of the steering spindle part adjoining the connection section, is increased, for the production of the steering spindle part as the starting produce is utilized an initially hollow-cylindrical tube, which is at least section-wise reshaped. For the formation of the connection section, a sleeve is set into an end section of the tube and the end section of the tube and of sleeve are subsequently jointly reshaped.
