Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、浮動型ディスクブレーキに用いるキャリパ
保護カバーに関するものである。Description: TECHNICAL FIELD The present invention relates to a caliper protection cover used for a floating disc brake.
ディスクロータを挾みつける摩擦パッドの一方をピス
トンで加圧し、その反力でインナー側にスライドするキ
ャリパのアウター爪で他方の摩擦パッドを加圧する浮動
型ディスクブレーキは乗用車に広く普及しているが、性
能の安定性の面から最近ではオフロード車へも広がりつ
ゝある。Floating disc brakes, in which one of the friction pads sandwiching the disk rotor is pressed by a piston and the other friction pad is pressed by the outer pawl of a caliper that slides inward by the reaction force, are widely used in passenger cars, Recently, it has been spreading to off-road vehicles in terms of performance stability.
ところが、このオフロード車は、耐環境性に関する要
求条件が厳しい。However, this off-road vehicle has strict requirements for environmental resistance.
例えば、ディスクロータの回入側と回出側に設けるキ
ャリパスライド部のスライドピンは防錆のためにゴムブ
ーツを被せているが、そのブーツが露出したまゝである
とブッシュや飛石によって傷付けられる恐れがあるの
で、その防止策が要求される。For example, the slide pins of the caliper slide section provided on the inflow side and the outflow side of the disk rotor are covered with rubber boots for rust prevention, but if the boots are left exposed, they may be damaged by bushes or stepping stones. Therefore, measures to prevent it are required.
また、キャリパのブリッジ部中央の点検孔から内側に
水や泥が侵入するとブレーキの効きが悪くなったり、摩
擦パッドのスライド部が錆付いたり、付着した泥によっ
てパッドの摩耗が助長されたりするので、点検孔からの
泥水の侵入防止策も要求される。Also, if water or mud enters inside from the inspection hole in the center of the bridge part of the caliper, the effectiveness of the brake will be deteriorated, the sliding part of the friction pad will rust, and the abrasion of the pad will be promoted by the attached mud, Measures to prevent muddy water from entering inspection holes are also required.
このうち、スライド部のゴムブーツの保護について
は、ブーツ覆い部をパッドライナに一体化して設けると
云った案が提案されている。しかし、これは構造が複雑
で製造コストも高くなることから実用化には至っていな
い。Among them, with regard to protection of the rubber boot of the slide portion, a proposal has been proposed in which the boot cover portion is provided integrally with the pad liner. However, this has not been put to practical use because of its complicated structure and high manufacturing cost.
また、泥水の侵入対策としては、点検孔の縮小、廃止
が考えられるが、これはキャリパの重量増を招くだけで
キャリパの増強効果等は少なく、また、点検孔を透して
の内部目視が困難或いは不可能になるため、パッドの摩
耗状況の確認についても問題が出てくる。In order to prevent the intrusion of muddy water, it is conceivable to reduce or eliminate the inspection holes, but this only increases the weight of the calipers and has little effect on enhancing the calipers.In addition, internal visual inspection through the inspection holes is difficult. Since it becomes difficult or impossible, there is also a problem in checking the wear state of the pad.
本発明は、これ等の課題を解決するのに有効なキャリ
パ保護カバーを提供しようとするものである。The present invention seeks to provide a caliper protection cover that is effective in solving these problems.
本発明のキャリパ保護カバーは、キャリパのブリッジ

タの回入側、回出側の各キャリパスライド部を覆う第２
覆い部と、キャリパへの止めねじを通す孔と、固定部材
との相対変位によって摩擦パッドの摩耗量を示す表示基
準部を設けてあるものである。The caliper protection cover according to the present invention includes a first cover portion that covers an inspection hole at the center of the bridge portion of the caliper, and blades that extend from both sides on the inner side of the first cover portion to the inlet side and the outlet side of the disk rotor. A second cover that covers each of the caliper slide portions on the inflow side and the outflow side of the disk rotor.
A cover portion, a hole for passing a set screw to the caliper, and a display reference portion for indicating a wear amount of the friction pad by a relative displacement with respect to the fixing member are provided.
この保護カバーは、点検孔を通してキャリパのディス
ク通過溝内に臨み、アウター側摩擦パッドが摩耗限界に
達した位置でディスクロータの外周に乗り上げて摺接音
を発するパッド摩耗検出器を第１覆い部に装着しておく
と、より好ましい態様となる。The protective cover covers a pad wear detector that faces the inside of the disc passage groove of the caliper through the inspection hole, and rides on the outer periphery of the disc rotor at a position where the outer friction pad reaches the wear limit to generate a sliding contact sound. It is a more preferable mode to attach the camera to the camera.
第１覆い部は、キャリパの点検孔を塞いで内部への泥
水の侵入を防止する。The first covering portion covers the inspection hole of the caliper to prevent muddy water from entering the inside.
また、第２覆い部は、２個所のキャリパスライド部を
覆ってスライドピンに被せたゴムブーツを飛石等から保
護する。Further, the second covering portion covers the two caliper slide portions and protects the rubber boot covering the slide pin from flying stones and the like.
さらに、これ等の覆い部を有する本発明の保護カバー
は、金属薄板を略Ｔ字状に打抜き、キャリパ表面に沿う
ように部分的に曲げ加工すればよく、軽量のものを容易
に、安価に作ることができ、キャリパの重量増、コスト
増を招かない。Further, the protective cover of the present invention having these covering portions may be formed by punching a thin metal plate into a substantially T-shape and partially bending the metal plate along the caliper surface. It can be made without increasing the weight and cost of the caliper.
さらに、翼部に固定部材との相対位置変化によってパ
ッド摩耗量を示す表示基準部が存在するので、点検孔を
塞いでもパッド摩耗量の確認に支障が出ない。Further, since the wing has a display reference portion indicating the amount of pad wear by a change in the relative position with respect to the fixing member, even if the inspection hole is closed, there is no problem in confirming the amount of pad wear.
第１覆い部に摩耗検出器をもつものは摩耗限界を音に
よっても知ることができ、寿命パッドの交換時期が遅れ
る心配もない。The one having the wear detector in the first cover part can know the wear limit by sound, and there is no fear that the replacement time of the life pad is delayed.

る。10 is a caliper protection cover of the present invention. The protective cover 10 has a first covering portion 11 that covers the inspection hole 6 of the caliper bridge portion along the caliper surface at the center. In addition, the first cover portion has wings 12 extending toward the inlet side and the outlet side of the disk rotor D on both sides on the inner side. Both ends of the wing 12 are bent toward the disk side so as to form a substantially 1/4 circle (see FIG. 3), and this portion is used as a second covering portion 13 of the caliper guide portions 5, 5 '. It covers the gum boot attachment part.
14は翼の途中にあけた孔で、この孔に通した止めねじ
７をキャリパにねじ込んでカバー10をキャリパに固定す
る。Reference numeral 14 denotes a hole formed in the middle of the wing. The set screw 7 passing through the hole is screwed into the caliper to fix the cover 10 to the caliper.
15は翼のインナー側側縁であり、図示のカバーにおい

る。Reference numeral 15 denotes an inner side edge of the wing. In the illustrated cover, the side edge 15 is used as a display reference portion for pad wear. That is, when the pads 4 and 4 'wear, the distance 1 from the end surface 3a of the fixing member to the side edge 15 changes, whereby the wear amount of the pad can be known. In the embodiment, the side edge 15 is positioned at the position of the end face 3a when the pads 4, 4 'reach the wear limit in order to accurately determine the wear amount.

熱がこもり易い場合には、小窓16は放熱部として働くの
で好ましいものである。The first cover 11 may be provided with a small window 16 as needed. When the braking heat is likely to accumulate in the disc passage groove 8 of the caliper, the small window 16 is preferable because it functions as a heat radiator.
17は、板ばねを曲げ加工して作られた摩耗検出器であ

The detector 17 which is exposed to the inside is the pad 4 'on the outer side.
When the roller reaches the wear limit, it rides on the outer periphery of the disk rotor D as indicated by a chain line, and generates a sliding contact sound. Therefore, it is possible to know the pad replacement time by hearing the sound.
このほか、例示のブレーキはキャリパ中央部が凹んで
いるので、第１覆い部11のインナー側端部にスカート部
18を連設して凹み部の入口を塞いでいる。In addition, since the center of the caliper of the illustrated brake is concave, a skirt portion is provided at the inner side end of the first cover portion 11.
18 are connected in series to block the entrance of the recess.
以上述べたように、本発明のキャリパ保護カバーは、
キャリパの重量増、コスト増を最小限に抑えてキャリパ
スライド部のゴムブーツの保護、点検孔からの泥水侵入
防止の目的を達成することができるので、浮動型ディス
クブレーキの特性をオフロード車においてもいかんなく
発揮させることが可能になる。As described above, the caliper protection cover of the present invention
The purpose of protecting the rubber boot on the caliper slide and preventing muddy water from entering the inspection hole can be achieved while minimizing the increase in the weight and cost of the caliper. It is possible to show it without any difficulty.
また、固定部材との相対位置変化によってパッドの摩
耗量を表示する表示基準部を設けてあるので、パッドの
摩耗量管理にも支障が出ない。Further, since the display reference portion for displaying the amount of wear of the pad based on a change in the relative position with respect to the fixing member is provided, there is no problem in managing the amount of wear of the pad.
このほか、ディスクロータに接して音を出す板ばね製
の摩耗検出器は、従来はパッドの裏板に取付けていたの
で取付け構造に工夫を要したが、本発明のカバーを利用
すれば、この種検出器の使用も容易になる。In addition, a plate spring wear detector that emits a sound in contact with the disk rotor has conventionally required mounting device construction since it was mounted on the back plate of the pad. The use of a seed detector is also facilitated.
