Abstract
A steering column for a motor vehicle includes a steering shaft, mounted rotatably about a longitudinal axis in a steering column housing, and a rotation limiter, and has a smooth and quiet construction of the rotation limiter. The rotation limiter includes two oppositely directed flat spiral springs, which are operatively arranged between a coupling part, disposed in a rotationally secure manner on the steering shaft, and the steering column housing.
Claims20
A steering column for a motor vehicle, comprising:
- a steering column housing;
- a steering shaft mounted rotatably about a longitudinal axis in the steering column housing;
- and
- a rotation limiter comprising
- a coupling part that includes a coupling portion and a shaft portion that is disposed radially inwards of and radially spaced apart from the coupling portion such that a void exists radially between the coupling portion and the shaft portion, wherein the shaft portion of the coupling part is disposed in a rotationally secure manner on the steering shaft, and
- two oppositely directed flat spiral springs operatively arranged between the coupling portion of the coupling part and the steering column housing.

A steering column comprising:
- a steering shaft mounted rotatably about a longitudinal axis;
- and
- a rotation limiter comprising a coupling part disposed in a rotationally secure manner on the steering shaft and two oppositely directed flat spiral springs disposed on the coupling part, wherein a first of the two oppositely directed flat spiral springs is seated on an exterior surface of the coupling part, wherein an inner end of the first of the two oppositely directed flat spiral springs extends completely through an aperture in the exterior surface and radially into an interior of the coupling part.
A steering column comprising:
- a steering shaft mounted rotatably about a longitudinal axis;
- a rotation limiter comprising a coupling part disposed in a rotationally secure manner on the steering shaft and two oppositely directed flat spiral springs disposed on the coupling part;
- and
