Abstract
A rack and pinion steering system, particularly for motor vehicles, has a rack placed in an axially displaceable manner in a sealed housing and a pinion which can be driven by the steering wheel, which is placed rotatably in a steering gear housing which also serves to guide the rack in the region thereof which is engaged with the pinion at any given time. The end of the rack away from the pinion is guided by an additional bearing secured to the body or to a part attached to the body. A bellows extending between the steering gear housing, which is shortened in the axial direction of the rack, and the additional mounting, serves as the sealing housing.
