Rack-and-pinion steering for motor vehicles

摘要

A rack-and-pinion steering is presented, in which an at least partially hollow cylindrical rack is used to ventilate and evacuate the bellows and in which at least one evacuation groove is prepared in the connection pin of the ball joint housing. The evacuation groove feeds or removes the air from the interior of the bellows via the hollow cylindrical rack corresponding to the direction of movement of the steering system.
