Abstract
In a rack-and-pinion steering gear for motor vehicles, in which in a steering gear housing a pressure piece is guided within a stub having an axis normal to that of the steering-gear housing so that the pressure piece is longitudinally displaceable in the guide stub. A preloading force acts on the pressure piece at an angle to the direction of motion of the pressure piece such that the pressure piece is held in engagement with a side wall of the stub in either direction of movement of the rack.
Claims6
A steering gear for motor vehicles comprising:
- a steering-gear housing (2),
- a rack (3) supported in said housing (2) so as to be longitudinally displaceable therein,
- a drive pinion (5) connected to a steering shaft and being in engagement with said rack (3),
- said housing including a stub (8) defining a cylindrical opening (7) arranged opposite said drive pinion (3) and having an axis extending normal to said rack (3),
- a pressure piece (6) supported within said cylindrical opening (7) of the steering-gear housing (2) in such a way as to be longitudinally displaceable therein for engaging said rack (3) and transmitting to the rack (3) a preloading force which acts on said pressure piece (6), said preloading force acting on the pressure piece (6) being generated by a spring (9) which is supported, on the one hand, against the pressure piece (6) and, on the other hand, by a cover (16) which closes the stub (8) of the steering-gear housing (2),
- said preloading force having a direction so as to act on the pressure piece at an angle α with respect to the direction of motion of the pressure piece.
