本発明はデイスクブレーキの摩擦パツドの構

のが普通である。 In general, the friction pad of a disc brake consists of a friction material (generally called a lining) that is pressed against the rotor, and a hydraulic cylinder device or a reaction pawl of a caliper that transmits the pressing force to the friction material. It consists of a backing metal that firmly supports the friction material and presses it against the rotor. The former is usually made by hardening and molding metal fibers, natural fibers, or various compounded materials with synthetic resin, and semimetallic materials are also used. The latter is usually formed by punching a metal plate such as a steel plate.

固に裏金に固着支持されることなどの点が挙げら
れている。 By the way, the first issue that has traditionally been an issue in the construction of such friction pads is
Frictional heat is generated on the sliding surface of the rotor and friction material,
If this heat is transferred to the hydraulic system such as a hydraulic cylinder device through the friction pads and brake pistons, it may cause so-called vapor lock, which increases the temperature of the brake fluid in the cylinder.
The aim is to reduce the effects of this heat conduction (preventing vapor lock, etc.) as much as possible, or to reduce thermal deterioration of the rubber seal member and improve its durability by reducing heat conduction. To prevent so-called "brake squeal" by reducing the transmission of vibrations to the hydraulic cylinder device, etc. Thirdly, the friction material is pressed against the rotor by resisting the shearing action on the back metal. Points such as the fact that it is firmly and firmly supported by the backing metal are mentioned.

ものが提案されている。 In order to solve these various problems, for example, since the back metal itself is a member with good thermal conductivity in the conventional friction pad described above, it is necessary to
A thermally poor conductor is used for the adhesive layer of the backing metal, a shim plate is placed on the back of the backing metal of the friction pad to prevent vibration transmission, and a shim plate is added to the backing metal to improve shear strength. A device has been proposed in which a concave-convex fitting portion is formed on the adhesive surface of the friction material.

ム板が必要になつて組立て部品が増すなどの点で
ある。 However, even if these various ideas were effective for individual tasks, they were sometimes ineffective or problematic for other tasks. For example, if the backing metal and the friction material fit together unevenly, the relatively porous nature of the friction material exposed on the backside of the backing metal may absorb water and moisture, leading to rusting and even peeling, as well as other components. This requires a shim plate, which increases the number of parts to be assembled.

裏金を備えたデイスクブレーキ用摩擦パツドを提
供せんとするものである。 In view of these points, the present invention has been developed by using a single plate structure of a metal plate in place of the conventional back plate of a friction pad.
It is an object of the present invention to provide a friction pad for a disc brake equipped with a backing plate that can suitably deal with the various problems described above by having a double plate structure in the thickness direction at least in the area where the friction material is fixed. be.

るものである。 That is, the gist of the present invention is that the back metal plate formed by bending a single metal plate of the back metal material is
A friction pad for a disc brake is characterized in that it has a double plate structure in the thickness direction at least in the area where the friction material is fixed. This is characterized in that other metal plates, heat insulating materials, vibration damping materials, etc. are interposed between the overlapping of the heavy plates.

By using it as
It is designed to also function as a so-called "squeal prevention shim."
以上本発明を図面に示す実施例に基づいて説明

る。 1 to 3 respectively show basic configuration examples of the back metal in the friction pad for disc brakes of the present invention, and FIG. 1 A and B show the back metal material 1 ( This figure shows a case where a steel plate (omitted below) is bent in half to form a backing plate 2 having a double plate structure as a whole as shown in Fig. 1B. A back metal material 3 press punched into a predetermined shape is bent symmetrically between the left and right edges (corresponding to both sides in the circumferential direction of the rotor) to form a back metal 4 having a double plate structure as a whole, Furthermore, in FIGS. 3A, 3B, and 3C, after forming a protrusion on a part of the same back metal material 5, the entire structure is made into a double plate structure (third plate structure).
This figure shows the case where the back metals 6 and 6' are used as shown in Figure C).

用するブレーキ装置に応じて個々形成すればよ
い。 In the example shown in FIG. 3C, the front surface on the side where the convex portions 7, 7 of the double plate structure are formed forms the surface to which the friction material (not shown) is fixed. Although an example in which the engagement hole 8 for the pad suspension pin is formed and an example in which it is not formed are shown separately, these may be formed individually depending on the brake device to which it is applied.
第４図は、第３図ハに示した裏金６を用いてそ

質的に分離しており、１枚板の単板構造に比べて
熱伝導性、振動性の点で有利となる。 According to the friction pad having such a structure, since the back plate has a double plate structure, the two plate parts (hereinafter referred to as the front plate and the rear plate) are substantially separated by the double stack of plates. This makes it advantageous in terms of thermal conductivity and vibration properties compared to a single-plate structure.

例を示している。 Figures 5A to 5F show various configuration examples of the back plate having the double plate structure mentioned above. In the example in Figures C and D, the front plate and rear plate, which have a double structure, are An example is shown in which the engagement hole for the pad suspension pin is formed as a part of the single-plate structure of the rear plate only.

方がよいから、両者の要求を前板のみを加工によ
つて満足できることになる。 In addition, in the examples shown in Figures E and F, protrusions are formed on the front plate of the double plate structure to prevent the fixed friction material from easily peeling off against the shearing force generated between it and the back metal due to the force received during braking. It shows what was done.
It should be noted that such protrusion processing is not necessary on the rear plate of the back metal, and rather it is better not to process it because the contact surface of the piston that engages with the rear surface is one-sided, so the requirements of both parties are met. This can be achieved by processing only the front plate.

な状態があり、このときの裏金の変形防止を有効
に図ることを目的としたものである。 In the example shown in Fig. 6, the front and rear plates are spot-welded at multiple locations, and this is because a support (not shown) engages with the side surface of the back metal of the friction pad to receive the brake torque. In such cases, the engagement may be localized to the front plate due to wear of the friction material, and the purpose of this invention is to effectively prevent deformation of the back metal in this case.

10 The member inserted between the two effectively blocks the heat generated between the friction material and the rotor friction engagement surface from being transmitted to the piston side that engages with the back surface of the pad, or provides a vibration damping effect. can be obtained as needed, and especially when a punched metal material is used, a suitable air layer can be formed between the front plate and the rear plate based on the shape of the punched metal material. This is effective in terms of vibration absorption. In the example shown in FIGS. 8A and 8B, a part of the dissimilar material 13 inserted between the front plate 12 1 and the rear plate 12 2 of the back plate 12 having a double plate structure is This extending portion 14 is connected to the padded back metal 12.
By positioning the piston 15 between the back surface of the piston 15 and the piston 15 that engages with the piston 15, the effects of heat insulation and vibration absorption are further enhanced. Note 16
indicates a friction material fixed to the front surface of the front plate 12 1 of the back metal 12 .

なるものである。 As described above, the friction pad for a disc brake according to the present invention is characterized by a backing plate that is constructed by folding a single metal plate and stacking two plate-like parts, and it is different from the conventional metal plate. Compared to friction pads with a backing metal, selective processing of only the necessary parts of the backing metal, insulation materials such as plastic sheets and rubber,
It has various excellent benefits such as easy insertion of vibration absorbing material, and also has the advantage that it has fewer parts and is easier to process than friction pads made of multiple metal plates stacked on top of each other. Its usefulness is enormous.
