本発明は摩擦パツド表面の摩耗粉除去を目的と
してブレーキ用デイスクの改良に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a brake disc for the purpose of removing wear powder from the surface of a friction pad.
ブレーキ用デイスクに半径方向の溝を設けてノ
イズ防止、効力の安定化、フエード防止、ウオー
ターフエードの防止等を目的としたものは知られ
ている。しかしこれらにはデイスクの熱的強度が
低下するという欠点がある。
It is known that brake discs are provided with radial grooves for the purpose of preventing noise, stabilizing effectiveness, preventing fade, preventing water fade, etc. However, these have the disadvantage that the thermal strength of the disk is reduced.
本発明はこの問題に問題に対処してなされたも
ので、デイスクの熱的強度を低下させずにパツド
表面の摩耗粉の除去に効果のあるブレーキ用デイ
スクを提供したものである。 The present invention has been made to address this problem, and provides a brake disk that is effective in removing abrasion powder from the pad surface without reducing the thermal strength of the disk.

The gist of the present invention is to form an outer circumferential groove extending from the outer circumferential surface of the disk toward the center of rotation of the disk, and a groove or slit that is continuous with the outer circumferential groove and faces toward the center of rotation of the disk and is deeper than the outer circumferential groove. The present invention provides a brake disc characterized by the following characteristics, and thereby achieves the intended purpose.

条ないしスリツトは円周方向等間隔に２〜４本程
度設ければ十分である。 In the present invention, deep grooves are usually provided at the same location on both the front and back surfaces of the disk, but if the disk is a ventilated rotor, they may be provided at different locations on both surfaces. Further, it is sufficient to provide about 2 to 4 grooves or slits at equal intervals in the circumferential direction.
デイスクの本体１にはその内周部および外周部

The main body 1 of the disk is provided with four slits 2 at equal intervals in the circumferential direction, extending in the radial direction of the disk and penetrating the front and back sides of the disk except for the inner and outer circumferential portions.
又このスリツト２に続いてその半径方向延長線
上の外周部兩面には外辺に抜ける浅い外周溝３が
夫々形成されている。 Continuing from this slit 2, shallow outer circumferential grooves 3 are formed on both sides of the outer circumferential portion on the radial extension line thereof, respectively.

が安定する効果も得られる。 Slit 2 in the disk (rotor) as shown above.
By providing 2 to 4 of these, the abrasion powder generated on the pad 4 and the friction surface is removed to the outside through the slit 2 and the outer circumferential groove 3, and noise can be prevented. 3, the effect of stabilizing the wear coefficient can also be obtained.
又パツド摩擦面に発生するガスをスリツト２お

ド防止の作用もあり、例えばスリツト等のない場
合の摩擦係数0.19が0.31まで改善される。 Furthermore, since the gas generated on the friction surface of the pad is released to the outside through the slits 2 and the outer circumferential groove 3, there is also an effect of preventing fade, and for example, the friction coefficient of 0.19 when there is no slit etc. is improved to 0.31.

いのでデイスク（ロータ）の熱的強度が向上する
効果が得られる。 Furthermore, since the water adhering to the pad friction surface and the disc rotor surface is discharged to the outside through the slits 2 and the outer circumferential groove 3, water fade can be prevented. ) has the effect of improving the thermal strength.
