Abstract
Abstract of Disclosure A solid disk of a disk brake has a hat and a disk element which are joined to each other by a junction. The junction has a plurality of communication holes defined therein which provides communication between opposite sliding surfaces of the disk element. First cooling air flows along one of the sliding surfaces of the disk element, and second cooling air flows smoothly through the communication holes along the opposite sliding surface of the disk element for effectively cooling the disk element in its entirety.
Claims18
A disk brake rotor for a brake having a disk caliper, the rotor comprising:
- a hat for accommodating a hub unit which supports a wheel;
- a disk element spaced apart from said hat, and including opposite sliding surfaces slidingly engagable by said disk caliper for receiving braking force applied by said disk caliper;
- a plurality of junction members joining an inner end face of said hat to a radially inner periphery of said disk element;
- and
- a plurality of communication passages being defined between said junction members and providing communication between said sliding surfaces.
A disk brake comprising:
- a disk caliper for applying a braking force;
- and
- a disk rotor having a hat for accommodating a hub unit which supports a wheel and a disk element for receiving the braking force applied by said disk caliper, adjacent edges of said hat and said disk element being spaced from each other in radial and axial directions relative to said rotor, said adjacent edges being joined to each other by a junction, said disk element having opposite sliding surfaces slidingly engagable by said disk caliper;
- said disk rotor having plurality of communication passages defined in said junction and providing communication between said sliding surfaces;
- said disk rotor comprises a solid disk;
- and
- said junction between said hat and disk element has a plurality of communication holes defined therein as said communication passages.
A disk brake rotor for a brake having a disk caliper, the rotor comprising:
- a raised central portion for accommodating a hub unit;
- a disk element spaced apart from said raised central portion, and including opposite sliding surfaces slidingly engagable by said disk caliper for receiving braking force applied by said disk caliper;
- a plurality of junction members joining an inner end face of said raised central portion to a radially inner periphery of said disk element;
- and
- cooling means for cooling said opposite sliding surfaces of said disk element as it is rotated, said cooling means comprising a plurality of communication passages defined between said junction members and providing communication between said opposite sliding surfaces.
A disk brake comprising:
- a disk caliper for applying a braking force;
- a disk rotor having a raised central portion for accommodating a hub unit and a disk element for receiving the braking force applied by said disk caliper, adjacent edges of said raised central portion and said disk element being joined together by a junction, said disk element having opposite sliding surfaces slidingly engagable by said disk caliper;
- cooling means for cooling said opposite sliding surfaces of said disk element as it is rotated:
- said cooling means comprising a plurality of communication passages defined in said junction and providing communication between said opposite sliding surfaces;
- each said communication passage having portions which extend radially and axially of said disk element;
- and
- said disk element is a solid disk, said junction between said raised central portion and disk element comprising a plurality of spaced rims connecting said adjacent edges of said raised central portion and said disk element of the disk rotor, and said communication passages are defined between adjacent ones of said spaced rims.
