Abstract
Hub apparatus for isolating the frame of a lightweight vehicle from shock imparted to a wheel on which the vehicle is mounted, the hub apparatus comprising an inner annular axle hub to which the frame is directly connected; an outer annular wheel hub surrounding the inner hub and connected directly to the wheel; an intermediate annular resiliently compressible spring engaged against opposing surfaces of the inner and outer hubs and separating the opposing surfaces of the hubs from each other; the intermediate spring being compressible such that shock imparted to the wheel is absorbed by compression of the spring between the opposing surfaces of the hubs.
