Abstract
A floating type brake disc is provided which is capable of limiting the heat escape from a rotor to a hub to the extent possible and which can be made smaller in weight. In a plurality of circumferential positions of the hub, there are formed pin-receiving portions in a manner to enclose a connecting pin from three directions of a radially inward, one of circumferentially both sides and a radially outward of the brake disc. A tongue-shaped pin-receiving portion is formed on each of a plurality of inner circumferential positions of the rotor 1 so as to be elongated radially inward to pinch the connecting pin between the tongue-shaped pin-receiving portion and the pin-receiving portion that is formed in the hub.
Claims12
A floating type brake disc comprising:
- an annular rotor;
- and
- a hub disposed on an inside of the rotor, the rotor and the hub being connected together by a connecting pin at each of a plurality of circumferential positions,
- wherein a pin-receiving portion is formed at each of the plurality of circumferential positions on a periphery of the hub so as to receive therein the connecting pin in a manner to enclose the connecting pin from three directions of a radially inner direction, one of circumferentially both sides, and a radially outer direction of the brake disc, the pin-receiving portion having an opening on the other of circumferentially both sides, and
- wherein a tongue-shaped pin-receiving portion is formed at each of the plurality of inner circumferential positions of the rotor so as to be elongated radially inward to close the opening in the pin-receiving portion to be formed in the hub, the tongue-shaped pin-receiving portion being adapted to pinch the connecting pin between the tongue-shaped pin-receiving portion and the pin-receiving portion to be formed in the hub.
