Steering column having an electro-mechanical fixing device
First Claim
1. A steering column for a motor vehicle that is adjustable in at least one of a longitudinal direction or a vertical direction of the steering column, the steering column comprising:
- a casing tube that rotatably supports a steering spindle;
a holding part that is connectable to a body of the motor vehicle and includes two lateral cheeks between which the casing tube is disposed;
an electromechanical fixing device, wherein in a release position of the electromechanical fixing device the casing tube is adjustable relative to the holding part in the at least one of the longitudinal direction or the vertical direction of the steering column, wherein in a fixing position of the electromechanical device a set position of the casing tube is fixed relative to the holding part, the electromechanical fixing device comprisinga clamping bolt that passes through the two lateral cheeks of the holding part and is rotatable about an axis of the clamping bolt by way of an electric motor disposed in a housing as the electromechanical fixing device is opened and closed; and
a stroke-generating mechanism and a support bearing, wherein the two lateral cheeks of the holding part and the casing tube are disposed between the stroke-generating mechanism and the support bearing, wherein the stroke-generating mechanism comprises a first stroke-generating disk and a second stroke-generating disk, with the first stroke-generating disk being connected for conjoint rotation to the clamping bolt and the second stroke-generating disk being guided on the clamping bolt such that the second stroke-generating disk is axially movable in the housing, wherein the housing is mounted in a floating manner on the second stroke-generating disk.

Abstract
An adjustable steering column may include a casing tube that rotatably supports a steering spindle, a holding part that has two lateral cheeks between which the casing tube is positioned, and an electromechanical fixing device. In a release position of the fixing device, the casing tube may be adjustable relative to the holding part. In a fixing position, a set position of the casing tube may be fixed relative to the holding part. The fixing device may include a clamping bolt that passes through the lateral cheeks and is rotatable about its axis by an electric motor positioned in a housing as the fixing device is opened and closed, a cam mechanism, and a support bearing. The lateral cheeks and the casing tube may be positioned between the cam mechanism and the support bearing. A first cam disk of the cam mechanism may rotate with the clamping bolt, and a second cam disk may be guided on the clamping bolt so as to be axially movable in the housing. The housing may be mounted in a floating manner on the second cam disk.
