Abstract

A joint is disclosed for the swivel bearing of a casing tube of an inclination-adjustable steering column on a casing tube suspension, having a joint head which is held between laterally surrounding fork legs, coaxial passage bores in the surrounding fork legs from which a longitudinal section of a bearing axle projects into an opposite fitted seat of the joint head, and two bearing bushes which surround the projecting longitudinal section of their bearing axle and which are conically constructed on their outer circumference and engage in their associated, fittingly conical fitted seat. An axial loading of the bearing bushes tapering toward one another is by way of a screwed advance of their bearing axle by means of which the bearing bushes are pressed without play into their fitted seat. In order to permit a lower-cost manufacturing of the joint, both fitted seats of the joint head are arranged in the end area of a cylindrical bore which is widened by means of a chamfer to form a fitted seat, and the bearing bushes have a basic cylindrical shape and engage by means of a conically slanted end area into the assigned fitted seat of their bore, their end area being constructed to be r…
