Abstract: A rack and pinion steering system, especially for motor vehicles, has a toothed rack that can be axially displaced in a steering gear housing, a pinion driven by the steering wheel and actuating the toothed rack, and a spring-loaded pressure part supported in the steering gear housing which serves to generate a certain pressure between the toothed rack and the pinion. Measures to raise the coefficient of friction which come into frictional contact with each other--in each case only in the region corresponding to straight-ahead driving--are provided on one or more surfaces of the steering system. As a result of such measures to increase the coefficient of friction at certain friction points in the steering system relating to straight-ahead motion of the vehicle, it is a simple matter to achieve an increase in steering torque in the center region of the steering system without the need for geometrical changes to the steering system or an increase in the pressure between the toothed rack and the pinion.

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.
