Conventionally, this type of disc brake includes a caliper having caliper legs on both sides of the disc, a plurality of cylinders each having one caliper leg on the other caliper leg, and each cylinder. A piston provided inside;
a plurality of pad accommodating grooves located on each cylinder opening side of each of the caliper legs and formed with a curved surface having the same center as each cylinder 8; and each of the pad accommodating grooves for each of the caliper legs. It consists of a pair of friction pads consisting of a board with curved surfaces at both ends so as to be slidably inserted into the pad, and a friction member fixed to the surface of the board facing the disk. Supply liquid into each cylinder,
Each piston presses each friction pad toward a disk, sandwiching the disk to apply braking (for example, Japanese Patent Publication No. 42-7846
Publication No.).

By the way, when the disc brake is attached to the vehicle body, the disc is located between each caliper leg, and there is a disc passage groove between the caliper legs, but the groove width of this disc passage groove is not so large. It cannot be taken. This is because even if the friction member of the friction pad wears to its wear limit, it is necessary to guide the base plate of the friction pad so that it does not fall out of the pad accommodation groove.

このため、摩擦パツドの摩擦部材が摩耗限界に
達したときにも、デイスクブレーキを車体に取付
けたままの状態では摩擦パツドの交換をすること
はできない。そこで、まずデイスクブレーキを車
体から取外し、次に摩耗した摩擦パツドを新しい
摩擦パツドと交換するようにしている。
Therefore, even when the friction member of the friction pad reaches its wear limit, the friction pad cannot be replaced while the disc brake is still attached to the vehicle body. Therefore, the disc brake is first removed from the vehicle body, and then the worn friction pads are replaced with new ones.

However, in the conventional disc brake described above, although the pad housing groove serving as the torque receiving surface is formed in a curved surface with the same center as the cylinder, the substrate of the friction pad and the friction member are approximately located within the pad housing groove. They are simply formed into an oval or eyebrow shape so that they fit tightly together.

For this reason, in order to assemble a new friction pad,
Even if the disc brake is removed from the vehicle,
If the thickness of the friction pad is larger than the width of the disc passage groove, remove the bolts fixing the pair of calipers and
The problem is that the friction pad cannot be replaced with a new one unless it is disassembled into parts.

本考案はこのような従来技術の問題点に鑑みな

The present invention was devised in view of the problems of the prior art, and it is an object of the present invention to provide a disc brake in which the friction pads can be replaced with new friction pads without disassembling the caliper.

In order to achieve the above object, the feature of the structure adopted by the present invention is that each caliper leg located on both sides of the disc is provided with a friction member relief groove located between each pad accommodation groove. This is because the longitudinal groove width l 2 of the friction member relief groove is formed to be larger than the longitudinal width l 1 of the friction member of the friction pad.

With this configuration, even if the thickness of the friction member of the friction pad is increased, the longitudinal width of the friction member is smaller than the longitudinal groove width of the friction member escape groove, so the disc brake cannot be removed from the vehicle body. If you remove the new friction pad and pass it through the disc passage groove, the friction member will automatically pass through the friction member passage groove together with it, allowing you to install a new friction pad without disassembling the caliper. Can be assembled.

At this time, the torque along the rotational direction B of the disk 5 that each friction member 31B, 32B receives is applied to the substrate 31.
pad housing grooves 17, 18 in which the substrates 31A, 32A are slidably guided via the pads 27, 32A;
28 respectively, and furthermore Calipa 1 and 2.
is transmitted to the vehicle body 4 via. On the other hand, if the braking action is repeated, the friction members 31B and 32B will wear out, and each board 31A and 32A will advance toward the disk 5 along the pad accommodation grooves 17 and 18 and 27 and 28, but each pad accommodation groove 17, 18 and 27,
28 can be made sufficiently deep, even when only the respective substrates 31A and 32A are left, the respective substrates 31A and 32A can be connected to the calipers 1 and 2.
It will not fall off. Furthermore, friction member relief grooves 19 and 29 are formed between each pad housing groove 17 and 18 and between 27 and 28, respectively.
The longitudinal groove width l 2 of 29 is the friction member 31B, 32B.
The longitudinal width l is larger than 1 . As a result, when replacing the friction pads 31 and 32,
First, the caliper 1 that makes up the disc brake,
This is connected to the vehicle body 4 via the brackets 2D and 2E of 2.
Remove from. Next, when removing the worn friction pads, if the total thickness of the substrate and the friction member is larger than the disk passage groove, then the friction members 31B, 32
If B is moved to the friction member relief groove 29, 19 side on the opposite side and the substrates 31A, 32A are passed through the disk passage groove, the friction members 31B, 32B will also be in the relief groove 2.
9 and 19 automatically, and worn friction pads can be removed. Furthermore, in order to assemble new friction pads 31, 32, the substrate 31A,
32A through the disk passage groove, and the friction members 31B and 32B are passed through the friction member relief groove 2 on the opposite side.
9, 19, and pad housing grooves 17, 27,
18 and 28, the replacement of the friction pads is completed. As a result, the friction member 3 of the friction pads 31 and 32 is larger than the groove width in the thickness direction of the disk passage groove.
Even if the thickness dimensions of 1B and 32B are large, the friction pads 31 and 32 can be replaced with new ones without removing the bolts 3 and 3 and disassembling the calipers 1 and 2.

Thus, each pad housing groove 17, 18 is formed concentrically with the center O 1 , O 2 of the cylinder 11, 12,
Similarly, the pad housing grooves 27 and 28 are also used for the cylinder 21,
Since the cylinders 11 and 22 are formed concentrically with the centers O 1 ′ and O 2 ′ of the caliper 1, the cylinders 11 and
12, the pad housing grooves 17 and 18 can be simultaneously machined, and the other caliper 2 can be machined simultaneously.
Also, when drilling the holes in the cylinders 21 and 22, the pad housing grooves 27 and 28 can be machined at the same time, reducing the number of man-hours required to machine each caliper 1 and 2.
It can be processed at low cost.

The disc brake according to the present invention is as described in detail above, and since the cylinder and the pad housing groove are located in the same center, the pad housing groove can be machined at the same time as the cylinder hole of the caliper is machined. In addition, since the board of the friction pad has a shape with curved surfaces on both ends, it can be made vertically symmetrical, eliminating the risk of incorrect assembly when assembling it into the pad accommodation groove, and improving ease of assembly. can be improved. Further, each caliper leg is provided with a friction material relief groove located between each pad housing groove, and the longitudinal groove width of the friction material relief groove is formed to be larger than the longitudinal width of the friction member of the friction pad. Even if the thickness of the friction member is thicker than that of the disc passage part, the friction pad can be easily attached and removed by simply passing the board through the disc passage part without disassembling the caliper. .
