  • Intra-wheel rear suspension system for motorcycles
    Patent number: 5390757
    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.
