Title:
ブレーキディスク
Document Type and Number:
Japanese Patent JP7267051
Kind Code:
B2
Abstract:
To improve brake feeling of a brake disc including a waveform portion in which recessed portions and projecting portions are repeatedly formed over an outer circumference.A brake disc 1 includes an outer circumferential portion 2 including a waveform portion 10 in which recessed portions 10a and projecting portions 10b are repeatedly formed over an outer circumference, and in order for the outer circumferential portion 2 to have substantially uniform heat capacity distribution in a circumferential direction and in a radial direction, the outer circumferential portion 2 is formed such that a ratio of a difference in heat capacities among a plurality of circumferential sections in the outer circumferential portion, which are sectioned at an equal angle in the circumferential direction, relative to a heat capacity of each circumferential section is equal to or less than a first predetermined ratio, and a ratio of a difference in heat capacities among a plurality of radial sections in the outer circumferential portion, which are sectioned to have an equal length in the radial direction, relative to a heat capacity of each radial section is equal to or less than a second predetermined ratio.
