  • Patent number: 8777329
    Abstract: A wheel carrier for a motor vehicle in which the wheel carrier is typically manufactured from aluminum. The wheel carrier comprises a recess (1) for receiving an outer ring (2) of a wheel bearing (3). An inner ring (4) of the wheel bearing (3) is fixed in a hub (15) of a wheel flange (12) of a vehicle axle. An axial end of the outer ring (2) of the wheel bearing (3) abuts against a shoulder of the wheel carrier (6), and a rim section (5) of the wheel carrier (6) is at least partially deformed to abut an opposite axial end of the outer ring (2) of the wheel bearing (3).

  • Patent number: 8360453
    Abstract: A bearing mechanism for a transverse leaf spring mounted near a vehicle axle of a vehicle. The bearing mechanism has an outer bearing shell device and insertion devices, which are encompassed by the outer bearing shell device and comprise layer elements of different stiffness. The insertion devices are each disposed between the outer bearing shell device and the transverse leaf spring. First layer elements have a greater stiffness and are positioned between the transverse leaf spring and second layer elements with lower stiffness. The first layer elements are half-shell shaped and convex between end regions and oriented in the axial direction of the transverse leaf spring. The end regions of the first layer elements comprise regions that are concave with respect to the surface of the leaf spring, and free ends of which point away from the surface of the leaf spring.
