  • Composite disc rotor
    Patent number: 9657794
    Abstract: A composite disc rotor includes a disc main body, a coupling bracket and coupling units. Each of the coupling units includes a bobbin, a clip and a coupling bolt. A head part of the bobbin includes a torque receiving portion inserted in the notch and a projection projected in a circumferential direction from an end of the torque receiving portion. A pipe part of the bobbin is extended from the head part and is fitted in a coupling through hole of the disc main body. The clip includes a connecting portion between the torque receiving portion and the notch and a pressing portion extended from the connecting portion between the head part and the coupling bracket. The coupling bolt is inserted into each of through hole of the bobbin to fix the coupling bracket to the coupling unit.
