本発明は滑動キャリパ型ディスクブレーキに用いるため
の摩擦パッド組立体に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a friction pad assembly for use in a sliding caliper type disc brake.
通常、摩擦パッドはディスクブレーキのガイドに支持さ
れ、ブレーキ抗力はガイドを介してパッドから車輛枠へ
ど伝達される。普通はガイドとパッドとの間に間隙が設
けられてブレーキの作用および解放の間にパッドがディ
スクの方へと及びディスクから離れる方へと滑動する。Typically, the friction pad is supported by a guide of the disc brake, and braking force is transmitted from the pad to the vehicle frame via the guide. A gap is normally provided between the guide and the pad to allow the pad to slide towards and away from the disc during application and release of the brake.
ことができるようになされている。パッドがガイド」二
でがたつくことを防止するために、従来から、パッドを
ガイドに押しつけるように偏倚するためのがたつき防止
ばねをパッドに取付けることが提案されていた。It has been made possible. In order to prevent the pad from rattling on the guide, it has previously been proposed to attach an anti-rattle spring to the pad to bias the pad against the guide.

コイル部から外方に伸長した２つの腕とを有している。A bat assembly provided with an anti-rattle spring is described in the applicant's complete specification of British Patent Application No. 55727/74. The spring shown herein has a coiled portion and two arms extending outwardly from the coiled portion.
ばねは、ばねのコイル部を貴通して延びているピンによ
って、パッドの裏板に設置ノられた上方伸長突起に取付
けられている。The spring is attached to an upwardly extending projection located on the back plate of the pad by a pin extending through the coil portion of the spring.

る。In manufacturing this pad assembly, the need for the lugs through the bins requires larger blank material than would be required without the lugs, and therefore more scrap is produced when manufacturing the backing plate by stamping. This results in high manufacturing costs. The backing plate material must be of high quality and therefore cost high.

おける欠陥はパッドに不均一な側面負荷を与え、パッド
はパッドのガイド内で傾いてしまう。In order to reduce the amount of scrap, it has been proposed to position the anti-rattle spring in the groove of the back plate.
In this case, the pad holds the spring in place. This proposal has the disadvantage that the spring must be placed in the groove before the friction material is molded onto the backing plate. Therefore, the heat required in the molding process (1) can damage the spring and change its properties. As the pad cools down, the spring remains "fixed" and
The pad assembly cannot be adjusted for proper alignment within the brake. Such defects in alignment result in uneven side loads on the pad, causing the pad to tilt within the pad's guides.
本発明の目的は、従来提案されたパッド組立体の上述し
た欠点を克服する、少なくとも減じる、ことにある。It is an object of the present invention to overcome, or at least reduce, the above-mentioned disadvantages of pad assemblies previously proposed.

The pad assembly is shown fitting within the four sections 11. In this type of pad assembly, a notch 17 is provided on one side of the projection 8 to prevent the spring arm 6 from projecting beyond the plane of the rear surface 1A of the back plate.
