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.
