Description

本発明は、車両用ドラムブレーキに関し、詳しくは、ブレーキドラムに摺接するブレーキシューを拡縮自在に収容するバックプレートの補強構造に関する。   The present invention relates to a vehicular drum brake, and more particularly to a back plate reinforcing structure that accommodates a brake shoe slidably in contact with a brake drum.

従来、車両用ドラムブレーキでは、バックプレートを比較的薄い板材で形成し、強度を必要とするアクスル挿通孔の周囲や、ブレーキシューが当接するアンカー部材の取付位置に対応する部分に補強用の押当て板を取り付けたものや（例えば、特許文献１参照。）、バックプレートの外周縁部に円環状の補強部材を取り付けたもの（例えば、特許文献２参照。）があった。   Conventionally, in a drum brake for a vehicle, a back plate is formed of a relatively thin plate material, and a reinforcing press is provided around an axle insertion hole that requires strength, or a portion corresponding to an attachment position of an anchor member with which a brake shoe abuts. There are those with a backing plate attached (for example, see Patent Document 1) and those with an annular reinforcing member attached to the outer peripheral edge of the back plate (for example, see Patent Document 2).

しかし、上述の特許文献１のものでは、バックプレートがアクスルの端部に取り付けられる際に、アクスル挿通孔の周囲にはベアリング等の部品が配置されていることから、取付スペースの制約を受け、取付スペースに応じて押当て板の形状や肉厚を設定しなければならなかった。また、上述の特許文献２のものでは、バックプレートの外周部全体に補強部材が取り付けられていることから、重量が嵩んでいた。   However, in the thing of the above-mentioned patent document 1, when components, such as a bearing, are arranged around the axle insertion hole when the back plate is attached to the end portion of the axle, the mounting space is limited. The shape and thickness of the pressing plate had to be set according to the mounting space. Moreover, in the thing of the above-mentioned patent document 2, since the reinforcement member was attached to the whole outer peripheral part of a backplate, the weight increased.

そこで本発明は、取付スペースの制約を受けることなく、極力重量を増大させずにバックプレートを補強できる車両用ドラムブレーキを提供することを目的としている。   Therefore, an object of the present invention is to provide a vehicular drum brake that can reinforce a back plate without increasing the weight as much as possible without being restricted by a mounting space.

上記目的を達成するため、本発明の車両用ドラムブレーキは、バックプレートの内部に、ブレーキドラムに摺接するブレーキシューを拡縮自在に収容するとともに、該ブレーキシューをバックプレート側に付勢するシューホールド機構を備えた車両用ドラムブレーキにおいて、前記バックプレートの外周縁の車体取り付け時に上部となる部分を除いた位置に、フランジ状の補強板を取り付けたことを特徴としている。   In order to achieve the above object, a vehicle drum brake according to the present invention accommodates a brake shoe slidably in contact with a brake drum inside a back plate, and a shoe hold that urges the brake shoe toward the back plate. A vehicle drum brake having a mechanism is characterized in that a flange-shaped reinforcing plate is attached to a position excluding an upper portion when the vehicle body is attached to the outer peripheral edge of the back plate.

また、前記補強板は、前記バックプレートの反車体側となる外面から外方に突出すると好ましい。さらに、前記補強板は、車体取り付け時に、前記バックプレートの少なくとも前記シューホールド機構よりも下方となる位置に設けられると好適である。   The reinforcing plate preferably protrudes outward from an outer surface of the back plate on the side opposite to the vehicle body. Furthermore, it is preferable that the reinforcing plate is provided at a position at least below the shoe hold mechanism of the back plate when the vehicle body is attached.

本発明の車両用ドラムブレーキによれば、バックプレートの外周縁に補強板を取り付けたことにより、取付スペースの制約を受けることなくバックプレートを補強することができ、さらに、フランジ状の補強板でバックプレートの外周側を補強することにより、バックプレートを簡単な構造で、極力重量を増大させることなく補強することができる。また、バックプレートを車体に取り付けた状態で上部となるバックプレートの外周縁には、補強板を設けていないことから、補強板を伝って外部から雨水がバックプレートの内部に浸入することを抑制できる。   According to the vehicle drum brake of the present invention, by attaching the reinforcing plate to the outer peripheral edge of the back plate, the back plate can be reinforced without being restricted by the mounting space. By reinforcing the outer peripheral side of the back plate, the back plate can be reinforced with a simple structure and without increasing the weight as much as possible. In addition, there is no reinforcing plate on the outer periphery of the upper back plate with the back plate attached to the vehicle body, so it is possible to prevent rainwater from entering the back plate through the reinforcing plate. it can.

さらに、補強板を、バックプレートの反車体側の外面から外方に突出させたことにより、既存のドラムブレーキのバックプレートに、大幅な形状変更をすることなく簡単にバックプレートを補強することができる。   Furthermore, by making the reinforcing plate protrude outward from the outer surface of the back plate on the side opposite to the vehicle body, it is possible to easily reinforce the back plate on the back plate of the existing drum brake without making a significant shape change. it can.

また、車体取り付け時に、バックプレートの少なくともシューホールド機構よりも下方となる位置に補強板を設けたことにより、雨天時に補強板を伝って外部から雨水がバックプレートの内部に浸入することを抑制できる。   In addition, when the vehicle body is attached, the reinforcing plate is provided at a position lower than at least the shoe hold mechanism of the back plate, so that it is possible to prevent rainwater from entering the back plate from the outside through the reinforcing plate when it rains. .

It consists of. In each brake shoe 3, a substantially intermediate portion of the web 3 b is elastically held on the back plate 2 by a shoe hold pin 8 and a shoe hold spring 9, and the brake shoe 3 is attached by the shoe hold pin 8 and the shoe hold spring 9. A shoe hold mechanism 10 that biases toward the back plate side is configured. Further, between the webs 3b, a shoe return spring 11 is stretched inside the wheel cylinder 4, and a connecting spring 12 is stretched outside the anchor 5, so that both brake shoes 3 are always attached in the direction of reduced diameter. Further, an automatic braking gap adjusting device 13 is disposed so as to pass through the inner peripheral side of the spring portion 11a of the shoe return spring 11.

バックプレート２は、中央にアクスル挿通孔２ａが形成され、該アクスル挿通孔２ａの車体取り付け時における上部側には、ホイルシリンダ用の位置決め孔２ｂが穿設されている。アクスル挿通孔２ａの下部側には、アンカー取付部２ｃが、バックプレート２の板材を内部側に平行に隆出させて形成され、該アンカー取付部２ｃには、リベット孔２ｄ，２ｄが穿設されている。また、アクスル挿通孔２ａの左右両側部には、バックプレート２の板材を内部側に平行に隆出させて形成したレッジ面２ｅが、ブレーキシュー３と対応する位置にそれぞれ３個ずつ円弧状に配列されている。   The back plate 2 has an axle insertion hole 2a formed in the center, and a wheel cylinder positioning hole 2b is formed on the upper side of the axle insertion hole 2a when the vehicle body is mounted. An anchor mounting portion 2c is formed on the lower side of the axle insertion hole 2a by projecting the plate material of the back plate 2 in parallel to the inner side, and rivet holes 2d and 2d are formed in the anchor mounting portion 2c.
