    Abstract: In summary, the invention relates to a method for forming an end-side toothing arrangement of a roiling bearing, in particular a wheel bearing. The aim is to improve the uniformity of the end-side toothing arrangement and to allow a greater tooth depth. This is achieved by two method steps in that, in a first step before the reshaping of an end piece of a hub, a die is axially arranged on the rolling bearing in a preassembled state and, in a second step during the reshaping of the end piece and the shaping of the end-side toothing arrangement, the die radially delimits a radial recess of the rolling rivet collar as it forms. In addition, the die reduces or prevents radial widening of the inner ring.

  • Patent number: 8052332
    Abstract: In a wheel bearing assembly, an outer surface of a head portion of a link bolt contacts an inner surface of an end wall portion of a constant-velocity joint outer ring. A shaft portion of a link bolt is press-fit into a penetration hole of the constant-velocity joint outer ring. An external threaded portion of the link bolt is inserted into the central hole of a hub spindle so that the external threaded portion protrudes from an outer end surface of a hub wheel. A lock nut is fastened to the external threaded portion, so that the wheel hub and the constant-velocity joint outer ring are linked, and the first spline and the second spline are meshed so as to be capable of torque transmission.
