초록 ▼

A ventilated disk brake includes a pair of brake pads which is substantially the same as the prior art, and a rotor. The rotor has a brake-pad engaging portion in which a pair of brake-pad engaging walls are formed to be pressed between and by the pair of brake pads. A plurality of cooling ribs extend radially between the pair of brake-pad engaging walls. The cooling ribs are formed in such a manner that the weight distribution thereof is ununiform in the peripheral direction thereof along the brake-pad engaging portion. For example, the cooling ribs can be different in thickness, length and/or arrangement interval. such a design can be made on the basis of empirical data.

대표청구항 ▼

1. A ventilated disk brake comprising: a pair of brake pads; a rotor having a brake-pad engaging portion with a pair of brake-pad engaging walls arranged to be pressed between and by the pair of brake pads; a plurality of cooling ribs extending radially between the pair of brake-pad engaging walls, the spacing and thickness pattern of said ribs being randomized so that any identical spacing and thickness pattern is not repeated. 2. A ventilated disk brake of claim 1, wherein the number of the ribs is more than twenty. 3. A ventilated disk brake of claim 2, wherein the ribs are located along the whole of the brake-pad engaging portion. 4. A ventilated disk brake comprising: a pair of brake pads; a rotor having a brake-pad engaging portion with a pair of brake-pad engaging walls arranged to be pressed between and by the pair of brake pads; and a plurality of cooling ribs extending radially between the pair of brake-pad engaging walls, the thickness and pitch pattern of said ribs being randomized so that any identical pattern is not repeated. 5. A ventilated disk brake of claim 4, wherein the number of the cooling ribs is more than twenty. 6. A ventilated disk brake of claim 5, wherein the cooling ribs are located along the whole of the brake-pad engaging portion. 7. A ventilated disk brake comprising: a pair of brake pads; a rotor having a brake-pad engaging portion with a pair of brake-pad engaging walls arranged to be pressed between and by a pair of brake pads; and a plurality of cooling ribs extending radially between the pair of brake-pad engaging walls, the thickness pattern of said ribs being randomized so that any identical pattern is not repeated. 8. A ventilated disk brake of claim 7, wherein the number of the cooling ribs is more than twenty. 9. A ventilated disk brake of claim 8, wherein the cooling ribs are located along the whole of the brake-pad engaging portion in a non uniform manner. 10. A ventilated disk brake comprising: a pair of brake pads; a rotor having a brake-pad engaging portion with a pair of brake-pad engaging walls arranged to be pressed between and by the pair of brake pads; and a plurality of cooling ribs extending radially between the pair of brake-pad engaging walls, the circumferential spacing between and the thicknesses of said ribs being randomized in a manner such that uniformly distributed resonance waves are prevented from occuring. 11. A ventilated disk brake of claim 10, wherein the number of the cooling ribs is more than twenty. 12. A ventilated disk brake of claim 11, wherein the cooling ribs are located along the whole of the brake-pad engaging portion in a non uniform manner.
