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.

Abstract: A steerable vehicle knuckle has an inboard portion defining upper and lower arms, with a kingpin between them, and has an outboard portion defining a spindle that cooperates with a fluid driven motor. The arms define a cavity where an axle end portion is pivotally received. Fluid supply ports, which supply fluid to energize the motor, are located on an upper surface of the knuckle's inboard portion. Fluid drain lines extend within the knuckle from the motor to the cavity and are utilized to drain fluid from the motor. The supply ports and drain lines are each connected to separate hoses formed in a small arc that follows closely the circular curvature of the kingpin. This arrangement of port, lines, and hoses is less expensive to produce, easier to package, more robust, allows for faster steering reaction, and is easier to assemble than conventional arrangements.

Abstract: A birdcage assembly for a high performance vehicle includes a birdcage having an opening defined by an inner periphery. The birdcage is secured to a rear suspension of the vehicle and is maintained in a substantially vertical position. The opening is intended to receive a vehicle axle therethough. The opening has a bearing located therein, which includes an inner race, an outer race, and a plurality of rollers disposed between the inner race and the outer race. The inner race of the bearing is in communication and rotates with the vehicle rear axle. Further, the bearing is moveable with respect to the birdcage such that as the axle deviates from an orientation parallel to ground, the bearing can move with respect to the birdcage away from a vertical position. The floating aspect of the bearing with respect to the birdcage minimizes side loads on the birdcage are thus prolongs the life of the bearing.
