板でなるシムを介在することが、デイスクブレー
キの鳴き防止対策として有効な一手段であること
が知られている。(b) Conventional technology and its problems The back metal of the outer pad of a disc brake,
It is known that interposing a shim made of a thin metal plate between the back plate and the arm of the caliper in contact with the back plate is an effective means for preventing disc brake squeal.
また、上記のシムを部分的に切欠いたものとし
面圧分布を不均一にすることが、より効果的に鳴
きを防止できることも知られている。 It is also known that squealing can be more effectively prevented by partially cutting out the shim to make the surface pressure distribution non-uniform.
しかしながら、従来知られているシムによつて
は、高速走行中のブレーキ操作によつてロータの
温度が高温になつている場合に急減速した際発生
する鳴き（スキール）を効果的に防止することが
できない。 However, conventionally known shims cannot effectively prevent the squeal that occurs when the rotor suddenly decelerates when the temperature of the rotor becomes high due to brake operation while driving at high speed. I can't.
(ハ) 問題点を解決するための手段
この考案は、通常の運転状態においてはもとよ
り、上記のごとき過酷な状況において発生する鳴
きを防止するシムを提供することを目的としてい
る。(c) Means for solving the problem The purpose of this invention is to provide a shim that prevents the squealing that occurs not only under normal operating conditions but also under severe conditions such as those described above.
上記の目的を達成するために、この考案はロー
タ回入側へ片寄つた位置にロータ軸方向へ切込ん
だ切欠き部を設け、その切込み深さをキヤリパの
回入側腕部の長さを越えないように定め、その腕
部の先端部分をシムの一部に当接し得るようにし
た構成としたものである。 In order to achieve the above object, this invention provides a notch cut in the rotor axial direction at a position offset toward the rotor rotation side, and the depth of the cut is set to the length of the rotation side arm of the caliper. The tip of the arm is set so as not to exceed the shim, and the distal end of the arm can come into contact with a part of the shim.
上記のように構成することにより、アウタパツ
ドの回入側でかつロータ外周辺に近い部分の面圧
が回出側の面圧よりも低くなる面圧分布を示すこ
とになる。 With the above configuration, a surface pressure distribution is exhibited in which the surface pressure on the input side of the outer pad and the portion near the outer periphery of the rotor is lower than the surface pressure on the output side.
(ニ) 実施例
この考案に係るシム１は、第１図及び第２図に
示すようにアウタパツド２の裏金３の裏面と大略
等しいステンレススチール等の金属板から成るも
のであり、キヤリパの腕４とアウタパツド２の裏
金３との間に介在して使用される。(d) Embodiment As shown in FIGS. 1 and 2, the shim 1 of this invention is made of a metal plate made of stainless steel or the like, which is approximately the same as the back surface of the back metal 3 of the outer pad 2, and and the back metal 3 of the outer pad 2.
シム１は、ロータ５の前進時（その場合の回転
方向を矢印ａで示す）の回入側に片寄つた位置に
その外周辺からロータ５の軸方向へ切込んだ切欠
き部６を設けている。この切欠き部６は図示の場
合、シム外周辺の中央部から回入側且つロータ軸
側のコーナ部に向けて傾斜した斜辺６ａと、シム
外周辺の回入側端部から同コーナ部に向けて設け
た切込み辺６ｂとにより三角形に切欠かれたもの
である。 The shim 1 is provided with a notch 6 cut in the axial direction of the rotor 5 from its outer periphery at a position biased toward the rotation side when the rotor 5 moves forward (the rotation direction in that case is indicated by arrow a). There is. In the illustrated case, this notch 6 has an oblique side 6a that is inclined from the center of the outer periphery of the shim toward a corner on the rotation side and the rotor shaft side, and a slope 6a that slopes from the edge on the rotation side of the outer periphery of the shim to the corner. It is cut out in a triangular shape by the cut side 6b provided toward the side.
上記の切欠き部６の切込み深さは、装着状態に
おいて、キヤリパの腕４の回入側腕部４ａの長さ
を越えないように定められ、その腕部４ａの先端
部分はシム１の一部、図示の場合は傾斜辺６ａを
越えた部分に当接する。 The depth of cut of the notch 6 is determined so as not to exceed the length of the arm 4a on the retraction side of the arm 4 of the caliper in the installed state, and the tip of the arm 4a is located at one end of the shim 1. In the illustrated case, it abuts on a portion beyond the inclined side 6a.
上記のような切欠き部６を設けると、回入側腕
部４ａの先端部のみがシム１のロータ回転軸に寄
つた部分に当接し、回出側腕部４ｂはその全面が
当接するので、パツド２のロータ５に対する面圧
は回入側でかつロータ外周辺に近い部分の面圧が
回出側の面圧より低くなる分布を示す。 When the notch 6 as described above is provided, only the tip of the retraction side arm 4a comes into contact with the portion of the shim 1 near the rotor rotation axis, and the entire surface of the retraction side arm 4b comes into contact. The contact pressure of the pad 2 against the rotor 5 shows a distribution in which the contact pressure on the entry side and near the outer periphery of the rotor is lower than the contact pressure on the exit side.
なお、シム１の面にゴムコーテイング等の弾性
体のコーテイングを施すと、一層効果的である。 Note that it is even more effective to coat the surface of the shim 1 with an elastic material such as rubber coating.

よつて確認することができた。(E) Effect By having the above-mentioned surface pressure distribution, it is effective to prevent the occurrence of squeal, especially when the rotor temperature becomes high due to brake operation while driving at high speed. The ability to effectively prevent this occurrence was confirmed through an experiment in which the device was mounted on an actual car and driven.
