Wheel hub, brake disc, bearing flange linked by threaded fasteners such as mechanical system called wheel nipple, nipple to wheel clamping force as the research target, the wheel hub, fasteners, as the research object, through the theory and a series of comparative experiments, from the wheel material, usage, wheel hub fastener structure form the two aspects of analysis on wheel nipple clamps The effect of the tightness. The research results are useful for designing a wheel threaded joint with good clamping characteristics.
