Device for Securing a Casing Tube Shifting Module to the Casing Tube of a Steering Shaft of a Motor Vehicle

摘要

A steering column module includes a tubular jacket rotatably supporting a steering shaft, a switch module having a carrier including contact pressure surfaces, and a device for fastening the switch module to the tubular jacket. The device includes a clamp assembly between the tubular jacket and the switch module for exerting a clamping force on the tubular jacket. The clamp includes two half clamps each having two outwardly bent end flanges. The end flanges are axially movably accommodated in the carrier such that when the switch module is axially moved onto the tubular jacket the end flanges come into contact with axial end stops of the tubular jacket and the contact pressure surfaces of the carrier. The contact pressure surfaces exert forces on the end flanges as the switch module is axially moved onto the tubular jacket thus fastening the switch module to the tubular jacket with a clamping action.

1. A steering column module comprising:
a tubular jacket rotatably supporting a steering shaft, an outer surface of the tubular jacket having axial end stops; a tubular jacket switch module having a carrier, the carrier having contact pressure surfaces; a device for fastening the tubular jacket switch module to the tubular jacket, the device including a clamping member assembly situated between the tubular jacket and the tubular jacket switch module for exerting a clamping force on the tubular jacket in a radial direction; and wherein the clamping member assembly includes two half clamps, each half clamp having two outwardly bent end flanges, the end flanges being accommodated in an axially moveable manner in the carrier of the tubular jacket switch module in such a way that when the tubular jacket switch module is axially moved onto the tubular jacket the end flanges come into contact with the axial end stops of the tubular jacket and the contact pressure surfaces of the carrier, wherein the contact pressure surfaces exert forces on the end flanges which act in parallel to a tangential direction of the tubular jacket as the tubular jacket switch module is axially moved onto the tubular jacket causing the end flanges to move radially inward toward one another and thus fastening the tubular jacket switch module to the tubular jacket with a clamping action.
