Patent ID: 7779945

Claim:
A method for the production of a steering spindle part which forms a portion of a steering spindle to be used in a motor vehicle, said method comprising: providing a hollow cylindrical tube; forming a sleeve by applying a rough outer surface to the sleeve, the rough outer surface comprising teeth spaced around an outer circumference of the sleeve, each of the teeth extending along a longitudinal axis of the sleeve; and forming a connection section at an end of the hollow cylindrical tube, at least a portion of a length of the connection section having a wall thickness larger than a wall thickness of an adjoining main section of the hollow cylindrical tube, said forming the connection section including: applying the sleeve to an end section of the hollow cylindrical tube by pressing the sleeve into the end section of the hollow cylindrical tube such that the teeth of the rough outer surface form longitudinal grooves on an inner surface of the hollow cylindrical tube so as to create a joint configured to restrict rotation of the sleeve relative to the hollow cylindrical tube; and after said applying of the sleeve, jointly reshaping the end section of the hollow cylindrical tube and the sleeve such that creeping of a material of the hollow cylindrical tube and creeping of a material of the sleeve occurs; and applying an inner thread onto an inner wall surface of the connection section.
