Axially adjustable steering column for vehicles

摘要

An axially adjustable steering column for vehicles is disclosed which has an axially displaceable steering shaft which is surrounded by two steering column jacket parts which can be pushed together in a telescopic fashion. The jacket parts can be attached to one another by way of a clamp connection. The jacket parts are axially movable with respect to one another when the clamp connection is loosened with the displacement of the steering shaft. The clamp connection has at least one threaded pin which is radially movable with respect to the longitudinal axis of the steering column jacket parts and is received on the outer steering column jacket part in a threaded section and after its screwing-in movement presses against the internal steering column jacket part. A spring-loaded control cable is provided which acts in a rotating fashion on the threaded pin. For this purpose, the control cable surrounds a pin connecting part on the threaded pin, resting against a circular cross-section at least over a distance of one arcuate section.
