STEERING COLUMN FOR A MOTOR VEHICLE

摘要

A steering column for a motor vehicle, with a steering shaft, including a damping element for damping vibrations transmitted across the steering shaft. The damping element includes an inner damper part, rotatable about a longitudinal center axis, whose outer circumferential contour comprises several outer elevations, spaced apart in the circumferential direction about the longitudinal center axis and projecting radially outwardly, between which are located outer indentations of the outer circumferential contour of the inner damper part. An outer damper part encompasses the inner damper part and is rotatable about the longitudinal center axis, the inner circumferential contour of which comprises several inner elevations, spaced apart from one another in the circumferential direction about the longitudinal center axis and radially projecting inwardly, between which inner indentations of the inner circumferential contour are located. An elastomeric damping material is disposed between the inner damper part and the outer damper part.

1. A steering column for a motor vehicle, with a steering shaft, wherein a damping element is provided for damping vibrations transmitted via the steering shaft, and wherein the damping element comprises an inner damper part, rotatable about a longitudinal center axis, whose outer circumferential contour, viewed in cross section through the damping element, comprises several outer elevations, spaced apart from one another in the circumferential direction about the longitudinal center axis and radially projecting outwardly, between which outer indentations of the outer circumferential contour of the inner damper part are located, an outer damper part encompassing the inner damper part and rotatable about the longitudinal center axis, the outer damper part having an the inner circumferential contour, viewed in cross section through the damping element, comprising several inner elevations, spaced apart from one another in the circumferential direction about the longitudinal center axis of the rearward steering shaft segment and projecting radially inwardly, between which inner indentations are located of the inner circumferential contour of the outer damper part, and an elastomeric damping material disposed between the inner damper part and the outer damper part, an angular range α, over which a particular outer elevation of the outer circumferential contour of the inner damper part extends in the circumferential direction about the longitudinal center axis, is smaller than a particular angular range β over which a particular outer indentation of the outer circumferential contour of the inner damper part extends in the circumferential direction about the longitudinal center axis.
