Patent ID: 6948401

Claim:
A linear guide for transmitting a torque between a tubular housing, which is defined by a longitudinal axis and rotatable about the longitudinal axis, and a shaft, which is received in the housing and movable in the direction of the axis in relation to the housing, said linear guide comprising plural axial rolling bearings received in the housing in surrounding relationship to the shaft, wherein the plural axial rolling bearings are disposed in two radial planes in axial spaced-apart relationship, wherein the axial rolling bearings in each of the two radial planes have each two bearing members and a set of rolling bodies disposed between the bearing members, wherein one bearing member is constructed as bushing which is retained in the housing and defines a center axis which is shifted in parallel relationship at an offset to a normal which extends upon a longitudinal shaft axis and intersects the one bearing member, wherein the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft, wherein the shaft is a steering-column spindle having a polygonal configuration, with the surface areas having a concave shape, wherein at least two longitudinal sides adjoining one another in circumferential direction have each a said concave surface area.
