Abstract

A brake disc includes a hub component intended to be fixed to a wheel, a rotor component with which brake pads can be engaged, a coupling constituent for coupling the hub component and the rotor component together, and the hub component is provided with a plurality of hub recesses and the rotor component is provided with a plurality of rotor recesses. The coupling constituent limits relative circumferential movement between the hub component and the rotor component, and allows free relative axial movement between the hub component and the rotor component within a predetermined distance from 0.3 mm to 0.7 mm. The centre of a hub-side circle which includes the hub recess is located further radially inside than the centre of a rotor circle which includes the rotor recess. Occurrence of brake judder is reduced and the durability of the biasing device is improved.

Claims (6)

1. A brake disc comprising: a hub component intended to be fixed to a wheel; a rotor component with which brake pads can be engaged, the rotor component being coupled to a radially outer side of the hub component so as to be concentric with the hub component; and a coupling constituent for coupling the hub component and the rotor component together, the coupling constituent being configured to limit relative circumferential movement between the hub component and the rotor component and allow free relative axial movement between the hub component and the rotor component within predetermined distance.
2. The brake disc of Claim 1, wherein the hub component is provided with a plurality of hub recesses along an outer circumference of the hub component, and the rotor component is provided with a plurality of rotor recesses along an inner circumference of the rotor component, the hub recesses and the respective rotor recesses being opposed in pairs to form a plurality of coupling holes; wherein the coupling constituent comprises a rivet pin, the rivet pin including a body which passes through the coupling hole, and first and second large-diameter portions formed in respective end portions of the body, the first and second large-diameter portions being larger in diameter than the coupling hole; and wherein a gap of the predetermined distance which allows the free relative axial movement is formed between an axially inner surface of the first large-diameter portion and each of opposed surfaces of the hub component and the rotor component, the opposed surfaces being opposed to the axially inner surface of the first large-diameter portion.
3. The brake disc of Claim 2, wherein the predetermined distance is within a range from 0.3 mm inclusive to 0.7 mm inclusive.
4. The brake disc of Claim 2 or 3, wherein the coupling constituent further includes a biasing device for biasing the rivet pin away from the hub component side toward the rotor component side, the biasing device including a middle portion accommodated in the hub recess so as to receive one side of the body of the rivet pin, and first and second strips extending from the middle portion to respective ends of the biasing device, the first and second strips being inserted in respective radial gaps between the hub component and the rotor component to limit the relative circumferential movement between the hub component and the rotor component.
5. The brake disc of Claim 4, wherein the hub recesses are larger in radius than the rotor recesses, and the center of a hub-side circle which includes the hub recess as a partial circle of the hub-side circle is located further radially inside than the center of a rotor circle which includes the rotor recess as a partial circle of the rotor circle.
6. The brake disc of Claim 4 or 5, wherein the biasing device is an omega spring.
