ABSTRACT:
An intra-hub suspension system for a wheel, particularly a motorcycle wheel although it can be adapted for use in other vehicles, e.g., airplane wheels, etc. The wheel is provided with an outer hub that is rotationally mounted on a stationary inner hub. The inner and outer hubs have a substantial diameter, e.g., from about 50% to 80% of the wheel diameter to provide an inner hub chamber of sufficient dimension for housing of an intra-hub suspension system. The intra-hub suspension system is received within the inner hub compartment and is fixedly secured thereto. The suspension system comprises a stationary frame having, on its opposite vertical interior sides, an arcuate cam with a curvature substantially equal to the radius about the drive sprocket of the motorcycle. Received within the frame is a carrier mechanism having a plurality of bearings that serve as rolling followers of a cam surface. The carrier has an outboard shoulder opposite an outboard shoulder of the frame between which are captured a plurality of compression springs. At its opposite side, the frame and carrier have a second pair of opposed shoulders which coact reciprocally to the first set of shoulders and a second plurality of springs is captured between the second pair of opposed shoulders. The frame is fixedly secured to the inner hub and the carrier receives the support shaft for the rear wheel.
