  • Thermally conductive ring for a wheel assembly
    Patent number: 8955920
    Abstract: According to the present invention, a thermally conductive ring for a wheel assembly, which is inserted over a stud bolt that fixes a brake drum or disc of a vehicle to a wheel, is provided with a cylindrical main body having a cutaway portion in the lengthwise direction, and a heat-dissipating portion formed on at least one side of a surface and edge of the main body to increase the surface area. The thermally conductive ring of a wheel assembly facilitates the transfer of heat generated during braking and driving to the wheels and enables heat dissipation, to retain the initial design specifications of the vehicle while reducing the uneven wear of tires and one side brake, and improving cornering and ride quality.
