  • Radially mobile bearing for a shaft pertaining to a steering system
    Patent number: 7686515
    Abstract: A radially movable bearing for a shaft of a gear in a steering system includes a bush or outer ring that is supported in a receiving element of a mount or housing for the gear. In order to create a radially flexible bearing for the shaft of the gear, which movable bearing enables quiet operation for the entire service life of the gear, the outer ring or the bush is held by at least one support element that is inserted in a gap between the receiving element and the outer ring, and that is made of a material with elastomer behavior.

  • Electric servo-assisted steering system for motor vehicles
    Patent number: 7048088
    Abstract: An electric power assisted steering system for motor vehicles having a worm gear mechanism is operatively connected to a drive shaft of an electric drive motor. A radial load is applied to the worm by a prestressing device, the prestressing device being configured as a hydraulic pressure device. It is possible to connect the drive shaft to the worm by a coupling, and the worm is mounted in this region by a pivotable bearing.
