Abstract

A friction pad guide device for a disc brake, in which the liners (13, 14) of friction pads are bent perpendicularly at both side ends toward the back surface sides to form vertically bent portions (13a, 13b, 14a, 14b), which are slidably engaged with inner vertical guide surfaces (9a, 10a, 11a, 12a) respectively extending elevationally of a torque retainer, and the upper portions of which are bent perpendicularly toward the opposite side directions to form laterally bent portions (13c, 13d, 14c, 14d), which are slidably engaged with the inner lateral guide surfaces (9b, 10b, 11b, 12b), respectively of the torque retainer, thereby slidably suspending the friction pads from the torque retainers. The length (L) of the vertically bent portions (13a, 13b, 14a, 14b) is formed to be greater than the thickness (l) of the liners (13, 14), whereby damage to the guide is prevented by the increased sliding area. If the configuration is such that the guide portion ends at the disc portion, the liners (13, 14) are prevented from dropping from the guide when the friction pads are worn out. Further, it becomes unnecessary to finish the side end surfaces of the disc in the guide after casting the torque retainer.

ディ スク ブレーキの摩擦パッ ト'案内装置  Disk brake friction pad guide device
〔技術分野〕  〔Technical field〕
本発明は、 ディ スク ブレーキの摩擦パッ ド案内装置 に関するものである。  The present invention relates to a friction pad guide device for a disk brake.
〔背景技術〕  (Background technology)
従来、 ディ スク ブレーキにおいては、 ト ルク受部材 に、 摩擦パッ ド揷入空間が形成されると共に、 該挿入 空間を挾んだ枏対向する部分に一対の摩擦パッ ド案内 部が形成され、 この一対の摩擦パッ ド案内部は、 上下 方向に伸びる縦案内面と、 該縦案内面の上端よ り揷入 空間から離れる方向へ伸びる横案内面とを備えている。 そして、 上記挿入空間内へ配置された摩擦パッ ドは、 その裏面に一体化された裏金を介して、 前記一対の案 内部によ り、 ディスクの軸線方向 摺動自在として吊 下支持されている。  Conventionally, in a disc brake, a friction pad insertion space is formed in a torque receiving member, and a pair of friction pad guides are formed in opposing portions across the insertion space. The pair of friction pad guides includes a vertical guide surface extending vertically and a lateral guide surface extending away from the insertion space from the upper end of the vertical guide surface. The friction pad arranged in the insertion space is suspended and supported so as to be slidable in the axial direction of the disc by the inside of the pair of cases via a back metal integrated on the back surface. .
しかしながら、 従来の裏金は、 例えばブレス鋼板等、 比較的硬い金属材で単に平板状に形成されていたため、 次のよ うな種々の問題点が生じていた、 すなわち、 ① 裏金の ト ノレク受部材に対する摺動面積（接触面積） は、 その薄い板厚にのみ決定されて小さいため、 通 常ア ル ミ ニゥム等比較的軟らかい金属で鏡造される ト ルク受部材が 走行中の振動等を受けて裏金によ り損傷を受け易く、 このため硬い金属板からなる案  However, since the conventional back metal was simply formed of a relatively hard metal material such as a breath steel plate into a flat plate shape, there were the following various problems. The sliding area (contact area) is determined only by its thin plate thickness and is small. Therefore, the torque receiving member, which is usually made of a relatively soft metal such as aluminum, is subject to vibrations during traveling. It is susceptible to damage by the backing metal and is therefore made of a hard metal plate
_ΟΜΗ 内板を、 トルク受部材の案内部に別途貼着する必要 があった。 _ΟΜΗ The inner plate had to be separately attached to the guide of the torque receiving member.
② 摩擦パッ ドが、 案内部のディスク側端面から脱落 してしま う ことがあった。  (2) The friction pad sometimes came off the end face of the guide on the disk side.
⑤ 案内部のディ スクに面した端面は、 ト ルク受部材 の鏡造直後は抜き勾配のため傾斜しており、 裏金の 全側面を該案内部に接触させるには、 この傾斜面を ディスクの面に対して平行となるよ うに仕上げ加工 しなければならなかった。  端 The end face of the guide facing the disc is inclined immediately after the mirror-making of the torque receiving member due to the draft angle.To make all the sides of the backing metal contact the guide, this inclined face must be It had to be finished so that it was parallel to the surface.
このよ うな欠点を解決するため、 裏金の肉厚を大 きくすることも考えられるが、 摩擦パッ ドをデイス クに押付ける ビス ト ン等との寸法関係のこともあつ て肉厚増大には限度があ り、 しかも単に肉厚を厚く するだけでは上記①〜③の問題点を全て解消するこ とは事実上不可能であった。  To solve these drawbacks, it is conceivable to increase the thickness of the back metal.However, due to the dimensional relationship with the screws that press the friction pad against the disk, the increase in thickness is not possible. There is a limit, and it is virtually impossible to solve all of the above problems ① to ③ simply by increasing the wall thickness.
〔発明の開示〕  [Disclosure of the Invention]
本発明は 摺動部分となる裏金の両側端部分を独特 の形状に屈曲させるこ とによ り、 裏金の肉厚をこれま でのよ うに薄くしたまま、 裏金による トルク受部材の 損傷を防止し、 又、 案内部のディ スク側端面からの摩 擦パッ ドの脱落を防止し、 更に案内部傾斜面の仕上げ 加工を不要とするディスク ブレーキの摩擦パッ ド案内 装置を開示する。  The present invention prevents damage to the torque receiving member due to the back metal while keeping the thickness of the back metal as thin as before, by bending both end portions of the back metal, which are sliding parts, into unique shapes. Also disclosed is a friction pad guide device for a disc brake which prevents the friction pad from falling off from the disk-side end face of the guide portion and further eliminates the need for finishing the inclined surface of the guide portion.

That's right. The caliper 2 has a built-in cylinder device 2a, and its screws (not shown) are on the back side of the friction pad 5 (the same as the disc 4 and below). The leg 2 extends beyond the disc 4 of the caliper 2 and faces the rear surface of the other friction pad. Then, when pressurized oil is supplied to the cylinder device 2a by depressing a brake pedal (not shown), the brake oil is released. While the stone presses the friction pad 5 on one side of the disc 4, the caliper 2 moves under the pressure to move the other friction pad ό to the other side of the disc 4. Press As a result, the braking action is performed. The carrier 1 has a main body 1a located on one surface side of the disk 4 and an extension 1b extending from the upper end surface of the main body 1a to the other surface side of the disk 4.

以上述べたことから明らかなよ うに、 本発明の案内 装置は、 次のよ うな種々の効果を奏するものである。 As is clear from the above description, the guide device of the present invention has various effects as follows.
① ト ルク受部材の案内部と裏金との間の摺動面積が 大きくなるので、 該両者間に ト ルク受部材の損傷防 止用の案内板を別途設けることが不用になる。 (1) Since the sliding area between the guide portion of the torque receiving member and the back metal becomes large, it is not necessary to separately provide a guide plate for preventing damage to the torque receiving member between the two.

Since there is no sliding guide, it is not necessary to finish the end face of the disk after the torque receiving part is manufactured.
