  • Patent number: 8899119
    Abstract: A device for pressing a rack onto a pinion engaged with the rack, in particular for a steering system of a motor vehicle, comprising a pressure piece, which can be loaded in the direction of the rack and is displaceably guided in a housing, and comprising an adjusting device for compensating play that occurs in the steering system. In known devices, the play of the pressure piece must be set by way of an adjusting screw. This proves to be very complicated and problematic. An adjusting screw is therefore provided, wherein a spring washer is disposed between the adjusting screw and the adjusting device, and the adjusting device has a shoulder and the adjusting screw has a recess, or the adjusting device has the recess and the adjusting screw has the shoulder.

  • Patent number: 8794093
    Abstract: A device for pressing a rack onto a pinion engaging the rack, more particularly for a steering system of a motor vehicle, comprises a pressure piece which is slidably guided in a housing and which is loaded in the direction of the rack, and an adjusting device. Devices made of metal are known from the prior art, which, however, generate excessive noise emissions during operation. Therefore, the pressure piece is made of plastic and the adjusting device is made of metal and/or plastic.

  • Patent number: 7510045
    Abstract: A power-steering system, e.g., for a motor vehicle, having an electric motor, which transmits a steering-assist force via a belt transmission to a ball-screw transmission for displacing vehicle wheels, includes a cam, via which the ball-screw transmission and/or electric motor is supported in a steering-gear housing. The tension of a belt of the belt transmission is adjustable by rotating the cam in the steering-gear housing. The cam has at least one cutout on the circumference, and/or the steering-gear housing has at least one cutout in its inner wall. A locking element may be inserted into the cutout, in order to fix the cam in position with respect to the steering-gear housing. After being inserted, the locking element is operatively connected to the cam and the steering-gear housing.
