A steering column for motor vehicles with axially adjustable steering shaft and positive locking between an axially adjustable, non-rotatably mounted steering column jacket and a support bearing that forms a rigid part of the vehicle body is described, wherein the locking mechanism consists of teeth provided on the circumference of the steering column jacket and teeth engaging in same, which latter teeth are provided on a locking element movably anchored in the support bearing, as well as of wedge bodies which can be moved into a locked position that brings about locking. The locking element is able to perform a limited pivoting motion around an axis arranged at right angles to the longitudinal axis of the steering column and can be displaced in the direction of the plane of engagement of the teeth at least by one tooth pitch, wherein next to a wedge body which tensions during its functioning the teeth on the steering column jacket and on the locking element at right angles to the longitudinal axis of the steering column, further wedge bodies are provided, which during their functioning wedge the locking element in the direction of the plane of engagement of the teeth against the support bearing.

Steering column with vertically adjustable steering wheel for motor

A ball and socket joint for heavily loaded joint linkages in motor vehicles, comprises a ball stud with a spherical head, a socket embracing the spherical head and made of a material with limited elasticity, and a casing accommodating the socket and sealingly closed, on its side opposite to the ball stud, with a cambered cover of sheet metal. The cover applies by its inside and under biasing load against the deformable socket. In its portion contacting the socket, the cover is formed with a camber producing the effect that if the joint is loaded axially increasingly from the ball stud, the cover expands and becomes more tightly clamped in the casing.
