Description

本発明は、ブレーキディスクに対向して配置される摩擦パッドと、ブレーキディスクの軸方向に沿う摺動を可能として前記摩擦パッドを支承する支持部が設けられるブラケットと、前記摩擦パッドおよび前記支持部間に介装されるリテーナとを備えるディスクブレーキに関する。   The present invention relates to a friction pad disposed opposite to a brake disc, a bracket provided with a support portion for supporting the friction pad to enable sliding along the axial direction of the brake disc, the friction pad, and the support portion. The present invention relates to a disc brake including a retainer interposed therebetween.

ブレーキディスクの周方向に沿う摩擦パッドの両端と、ブラケットに設けられた支持部との間にリテーナが介装されるディスクブレーキが、たとえば特許文献１で開示されており、このものでは、ブラケットの支持部にブレーキディスクの外周部を配置するための溝が設けられており、ブレーキディスクの軸方向に沿うリテーナの位置を定めるようにした一対の爪が前記溝の内側面に係合するようにしてリテーナに設けられている。
特開平１０−１２２２７８号公報 For example, Patent Literature 1 discloses a disc brake in which a retainer is interposed between both ends of a friction pad along the circumferential direction of a brake disc and a support portion provided on the bracket. A groove for arranging the outer peripheral portion of the brake disc is provided in the support portion, and a pair of claws adapted to determine the position of the retainer along the axial direction of the brake disc are engaged with the inner surface of the groove. Provided in the retainer.
Japanese Patent Laid-Open No. 10-122278

ところが上記従来のもののリテーナに設けられる爪は、リテーナをブラケットの支持部に組付ける際の位置決め機能を果たすべく、リテーナの一部を折り曲げて形成される平板状のものであり、リテーナをブラケットの支持部に強固に支持する機能を有してはいない。そのため、ブレーキディスクの周方向に振動する方向の力が摩擦パッドに作用したときには、リテーナがブラケットの支持部に接触してラトル音が発生する。   However, the claw provided on the conventional retainer is a flat plate formed by bending a part of the retainer so as to perform a positioning function when the retainer is assembled to the support portion of the bracket. It does not have a function of firmly supporting the support part. Therefore, when a force in the direction of vibration in the circumferential direction of the brake disk is applied to the friction pad, the retainer comes into contact with the support portion of the bracket and a rattle sound is generated.

本発明は、かかる事情に鑑みてなされたものであり、ブレーキディスクの周方向に沿う力の作用にもかかわらずラトル音の発生を防止し得るようにしたディスクブレーキを提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a disc brake capable of preventing the generation of rattle noise despite the action of force along the circumferential direction of the brake disc. .

上記目的を達成するために、本発明は、ブレーキディスクに対向して配置される摩擦パッドと、ブレーキディスクの軸方向に沿う摺動を可能として前記摩擦パッドを支承する支持部が設けられるブラケットと、前記摩擦パッドおよび前記支持部間に介装されるリテーナとを備えるディスクブレーキにおいて、前記摩擦パッドから離反するにつれて相互に近接するように傾斜しつつ前記摩擦パッドとは反対側に臨む傾斜面が前記支持部の両側面にそれぞれ形成され、前記支持部の摩擦パッド側に臨む面に一部を当接させる前記リテーナに、前記傾斜面に弾発的に当接して前記支持部を前記ブレーキディスクの軸方向に沿う両側から弾発的に挟持する一対の挟着爪）が設けられることを特徴とする。 In order to achieve the above object, the present invention provides a friction pad disposed opposite to a brake disc, and a bracket provided with a support portion for supporting the friction pad so as to be able to slide along the axial direction of the brake disc. In the disc brake including the friction pad and the retainer interposed between the support portions, an inclined surface that faces the opposite side to the friction pad while being inclined so as to be close to each other as the distance from the friction pad is increased. The retainer is formed on both side surfaces of the support portion, and partly contacts the surface of the support portion facing the friction pad. A pair of sandwiching claws that are resiliently sandwiched from both sides along the axial direction of each other is provided.

本発明の上記構成によれば、一対の挟着爪が、ブラケットの支持部を両側から弾発的に挟持することによる弾発保持力により、ブレーキディスクの周方向に沿うリテーナの変位が極力生じないようにすることができ、ブレーキディスクの周方向に沿う力が作用してもリテーナが極力振動しないようにしてラトル音の発生を防止することができる。しかも傾斜面から挟着爪すなわちリテーナに作用する反力には、ブレーキディスクの周方向に沿う分力が生じ、ブレーキディスクの周方向に沿う力が作用してもリテーナの振動をより確実に防止することができるとともに、リテーナが支持部から離脱しないようにすることができる。 According to the above configuration of the present invention, the retainer is displaced along the circumferential direction of the brake disc as much as possible due to the resilient holding force by the pair of clamping claws resiliently clamping the support portion of the bracket from both sides. The retainer does not vibrate as much as possible even when a force along the circumferential direction of the brake disk is applied, thereby preventing the generation of rattle noise . Moreover, the reaction force acting on the clamping claws or retainer from the inclined surface generates a component force along the circumferential direction of the brake disc, and even more reliably prevents the retainer from vibrating even if the force along the circumferential direction of the brake disc acts. It is possible to prevent the retainer from being detached from the support portion.

次にこの実施例の作用について説明すると、摩擦パッド２０…の裏金２４…がブレーキディスク１９の周方向両端部に備える肩部２４ａ，２４ａ…は、ブラケット２２が備える支持部２２ａ，２２ａにリテーナ２３，２３を介して支承されるのであるが、リテーナ２３には、ブレーキディスク１９の軸方向に沿う両側から支持部２２ａを挟む一対の挟着爪２３ｄ，２３ｄが設けられるので、リテーナ２３…をブラケット２２の支持部２２ａ…に組付ける際に、ブレーキディスク１９の軸方向に沿う位置決めを容易とすることができる。   Next, the operation of this embodiment will be described. Shoulder portions 24a, 24a,... Provided on the opposite ends of the brake disk 19 in the back plate 24 of the friction pads 20 ... are retained on the support portions 22a, 22a provided on the bracket 22. 23, the retainer 23 is provided with a pair of clamping claws 23d and 23d that sandwich the support portion 22a from both sides along the axial direction of the brake disc 19, so that the retainer 23 is attached to the bracket. When assembling to the support portions 22a of the 22, the positioning of the brake disk 19 along the axial direction can be facilitated.

しかも前記挟着爪２３ｄ…は、ブラケット２２の支持部２２ａを両側から弾発的に挟持するものである。したがってリテーナ２３の第１および第２保持部２３ａ…，２３ｂ…と前記支持部２２ａとの間に作用する摩擦力に、前記挟着爪２３ｄ…が発揮する弾発力を加えた力で、ブレーキディスク１９の周方向に沿ってリテーナ２３に作用する力に対抗することになり、ブレーキディスク１９の周方向に沿ってリテーナ２３に作用する力に比較的大きな力で対抗してリテーナ２３をブラケット２２の支持部２２ａに保持することができる。この結果、ブレーキディスク１９の周方向に沿うリテーナの変位が極力生じないようにすることができ、ブレーキディスク１９の周方向に沿う力が作用してもリテーナ２３…が極力振動しないようにしてラトル音の発生を防止することができる。   In addition, the clamping claws 23d are used to elastically clamp the support portion 22a of the bracket 22 from both sides. Therefore, the braking force is a force obtained by adding the elastic force exerted by the clamping claws 23d to the friction force acting between the first and second holding portions 23a, 23b, and the support portion 22a of the retainer 23. The force acting on the retainer 23 along the circumferential direction of the disk 19 is countered, and the force acting on the retainer 23 along the circumferential direction of the brake disk 19 is counteracted by a relatively large force to fix the retainer 23 to the bracket 22. It can hold | maintain to the support part 22a. As a result, the displacement of the retainer along the circumferential direction of the brake disc 19 can be prevented as much as possible, and even if a force along the circumferential direction of the brake disc 19 acts, the retainer 23. Generation of sound can be prevented.

しかもブラケット２２における支持部２２ａの両側面には、摩擦パッド２０から離反するにつれて相互に近接するように傾斜して摩擦パッド２０とは反対側に臨む傾斜面３５ａ，３５ａを有する突部３５，３５が突設されており、前記挟着爪２３ｄ…は、前記支持部２２ａの摩擦パッド２０側に臨む面に第１および第２保持部２３ａ，２３ｂの一部を当接させつつ前記両突部３５…の前記傾斜面３５ａ…に当接する。   In addition, on both side surfaces of the support portion 22a of the bracket 22, projections 35 and 35 having inclined surfaces 35a and 35a that are inclined so as to approach each other as they are separated from the friction pad 20 and face the opposite side of the friction pad 20. The clamping claws 23d are arranged so that the projecting portions of the first and second holding portions 23a and 23b are brought into contact with the surface of the support portion 22a facing the friction pad 20 side. 35 abuts on the inclined surfaces 35 a.

このように一対の挟着爪２３ｄ…が突部３５…の傾斜面３５ａ…に弾発的に接触することにより、傾斜面３５ａ…から挟着爪２３ｄ…すなわちリテーナ２３に作用する反力には、ブレーキディスク１９の周方向に沿う分力が生じ、ブレーキディスク１９の周方向に沿う力が作用してもリテーナ２３の振動をより確実に防止することができるとともに、リテーナ２３が支持部２２ａから離脱しないようにすることができる。   In this way, when the pair of clamping claws 23d are elastically contacted with the inclined surfaces 35a of the projections 35 ..., the reaction force acting on the clamping claws 23d ..., that is, the retainer 23 from the inclined surfaces 35a ... Further, a component force along the circumferential direction of the brake disc 19 is generated, and even if a force along the circumferential direction of the brake disc 19 is applied, vibration of the retainer 23 can be more reliably prevented, and the retainer 23 can be prevented from the support portion 22a. It can be prevented from leaving.

以上、本発明の実施例を説明したが、本発明は上記実施例に限定されるものではなく、特許請求の範囲に記載された本発明を逸脱することなく種々の設計変更を行うことが可能である。   Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. It is.

たとえば上記実施例では、支持部２２ａの両側面に突設される台形状の突部３５…で傾斜面３５ａ…を形成するようにしたが、支持部２２の両側面に凹設される凹部で前記傾斜面を形成するようにしてもよい。   For example, in the above embodiment, the inclined surfaces 35a are formed by the trapezoidal protrusions 35 that protrude from both side surfaces of the support portion 22a. The inclined surface may be formed.
