上記のブレーキパッドにおいては、裏板のディスクロータ回転方向の全長にわたって金属部材を配置しているため、裏板に樹脂を用いても軽量化の度合いが低くなってしまう。また、金属部材と樹脂とが、ピストン等の押圧部材の押圧力による剪断方向に沿って固着面を有しているため、使用状況によっては経年的に押圧部材の押圧力で分離してしまう懸念があった。   In the above brake pad, since the metal member is disposed over the entire length of the back plate in the disk rotor rotation direction, the weight reduction is reduced even if resin is used for the back plate. In addition, since the metal member and the resin have a fixing surface along the shearing direction due to the pressing force of the pressing member such as a piston, there is a concern that the pressing member may be separated by the pressing force of the pressing member over time depending on the use situation. was there.

したがって、本発明は、ブレーキパッドの軽量化を図りつつ、裏板の分解の可能性を低減できるブレーキパッドの提供を目的とする。   Accordingly, an object of the present invention is to provide a brake pad that can reduce the possibility of disassembly of the back plate while reducing the weight of the brake pad.

上記目的を達成するために、本発明は、裏板が、摩擦材が貼付される樹脂部材と、相互間に前記樹脂部材を挟んで該樹脂部材のディスクロータ回転方向両端側にそれぞれ固着され支持部材に支持される一対の金属製のパッドガイド部材とを有し、該一対の金属製のパッドガイド部材は、前記樹脂部材よりも薄肉に形成され該樹脂部材と肉厚方向に重なって固着される薄肉部を有する。   In order to achieve the above object, according to the present invention, a back plate is fixed to and supported by a resin member to which a friction material is stuck, and both ends of the resin member in the disk rotor rotation direction with the resin member interposed therebetween. A pair of metal pad guide members supported by the member, and the pair of metal pad guide members are formed thinner than the resin member and are fixed to the resin member so as to overlap in the thickness direction. It has a thin part.

本発明によれば、軽量化を図りつつ裏板の分解の可能性を低減できる。   According to the present invention, the possibility of disassembling the back plate can be reduced while reducing the weight.

本発明の一実施形態に係るブレーキパッドを図面を参照して以下に説明する。   A brake pad according to an embodiment of the present invention will be described below with reference to the drawings.

図１は、本実施形態に係るブレーキパッド１０が用いられるディスクブレーキ１１を示すものである。このディスクブレーキ１１は、自動車等の車両制動用のもので、キャリア（支持部材）１２と、一対のブレーキパッド１０と、キャリパ１３とを備えている。   FIG. 1 shows a disc brake 11 in which a brake pad 10 according to this embodiment is used. The disc brake 11 is for braking a vehicle such as an automobile, and includes a carrier (support member) 12, a pair of brake pads 10, and a caliper 13.

キャリア１２は、制動対象となる図示略の車輪とともに回転するディスクロータ１５の外径側を跨ぐように配置されて車両の非回転部に固定される。一対のブレーキパッド１０は、ディスクロータ１５の両面に対向配置された状態でディスクロータ１５の軸線方向に摺動可能となるようにキャリア１２に支持される。キャリパ１３は、ディスクロータ１５の外径側を跨いだ状態でディスクロータ１５の軸線方向に摺動可能となるようにキャリア１２に支持されてブレーキパッド１０をディスクロータ１５に押圧することによりディスクロータ１５に摩擦抵抗を付与する。なお、以下においては、ディスクロータ１５の半径方向をディスク半径方向と称し、ディスクロータ１５の軸線方向をディスク軸線方向と称し、ディスクロータ１５の回転方向をディスク回転方向と称す。   The carrier 12 is disposed so as to straddle the outer diameter side of the disk rotor 15 that rotates together with a wheel (not shown) to be braked, and is fixed to a non-rotating portion of the vehicle. The pair of brake pads 10 are supported by the carrier 12 so as to be slidable in the axial direction of the disk rotor 15 while being opposed to both surfaces of the disk rotor 15. The caliper 13 is supported by the carrier 12 so as to be slidable in the axial direction of the disc rotor 15 while straddling the outer diameter side of the disc rotor 15, and presses the brake pad 10 against the disc rotor 15. Friction resistance is given to 15. In the following description, the radial direction of the disk rotor 15 is referred to as a disk radial direction, the axial direction of the disk rotor 15 is referred to as a disk axial direction, and the rotational direction of the disk rotor 15 is referred to as a disk rotational direction.

キャリパ１３は、ディスクロータ１５を跨いだ状態でキャリア１２に支持されるキャリパボディ２０と、キャリパボディ２０内に保持されてディスクロータ１５の一面側に対向するように配置されるピストン２１とを有している。   The caliper 13 has a caliper body 20 that is supported by the carrier 12 across the disk rotor 15 and a piston 21 that is held in the caliper body 20 and arranged to face one surface of the disk rotor 15. is doing.

キャリパボディ２０は、シリンダ部２５と、ブリッジ部２６と、爪部２７とを有して一体的に構成されている。   The caliper body 20 includes a cylinder portion 25, a bridge portion 26, and a claw portion 27, and is configured integrally.

シリンダ部２５は、ディスクロータ１５側に開口するようにディスク軸線方向に沿うボア３０が形成された有底筒状をなしており、ディスクロータ１５の一方の面側に対向配置されている。ピストン２１はボア３０内に摺動可能に挿入されている。ブリッジ部２６は、ディスクロータ１５を跨ぐためにシリンダ部２５の径方向外方でディスクロータ１５の軸方向へ延びて形成されている。爪部２７は、ブリッジ部２６のシリンダ部２５とは反対側からディスク半径方向内方に延出してディスクロータ１５の他方の面側に対向するようになっている。   The cylinder portion 25 has a bottomed cylindrical shape in which a bore 30 is formed along the disk axial direction so as to open to the disk rotor 15 side, and is disposed opposite to one surface side of the disk rotor 15. The piston 21 is slidably inserted into the bore 30. The bridge portion 26 is formed to extend in the axial direction of the disk rotor 15 outside the cylinder portion 25 in order to straddle the disk rotor 15. The claw portion 27 extends inward in the disk radial direction from the opposite side of the bridge portion 26 to the cylinder portion 25 and faces the other surface side of the disk rotor 15.

シリンダ部２５の底部には、図示略のブレーキ配管に接続される配管接続穴３１が形成されている。そして、キャリパ１３は、ボア３０内にブレーキ配管を介して導入される液圧によりピストン２１をディスクロータ１５側に前進させ、ピストン２１でインナ側のブレーキパッド１０を押圧してディスクロータ１５に接触させる。また、キャリパ１３は、ピストン２１の押圧反力でキャリア１２に対してシリンダ部２５をディスクロータ１５から離す方向に摺動して、爪部２７でアウタ側のブレーキパッド１０を押圧してディスクロータ１５に接触させる。このようにして、ピストン２１と爪部２７とで両側のブレーキパッド１０を挟持してディスクロータ１５に押圧して摩擦抵抗を発生させ、制動力を発生させる。   A pipe connection hole 31 connected to a brake pipe (not shown) is formed at the bottom of the cylinder part 25. The caliper 13 advances the piston 21 toward the disc rotor 15 by the hydraulic pressure introduced into the bore 30 via the brake pipe, and presses the inner brake pad 10 with the piston 21 to contact the disc rotor 15. Let Further, the caliper 13 slides in the direction in which the cylinder portion 25 is separated from the disk rotor 15 with respect to the carrier 12 by the pressing reaction force of the piston 21, and the outer brake pad 10 is pressed by the claw portion 27 to press the disc rotor. 15 is contacted. In this way, the brake pads 10 on both sides are sandwiched between the piston 21 and the claw portion 27 and pressed against the disk rotor 15 to generate a frictional resistance, thereby generating a braking force.

なお、ボア３０の軸線方向における中間位置には、ピストン２１との隙間をシールするピストンシール３３が保持されており、ボア３０の軸線方向における最も開口部側には、ピストン２１との間に円環状のブーツ３４が介装されている。   A piston seal 33 that seals the gap with the piston 21 is held at an intermediate position in the axial direction of the bore 30, and a circle between the piston 21 and the piston 30 is located closest to the opening in the axial direction of the bore 30. An annular boot 34 is interposed.

ブレーキパッド１０は、制動時に一面側がディスクロータ１５に当接する摩擦材４０と、この摩擦材４０の他面側に貼付されキャリア１２によって摺動可能に支持される裏板４１とからなっている。   The brake pad 10 includes a friction material 40 whose one surface abuts against the disk rotor 15 during braking, and a back plate 41 that is affixed to the other surface of the friction material 40 and is slidably supported by the carrier 12.

摩擦材４０は、結合材としてのフェノール樹脂を主体として構成されている。   The friction material 40 is mainly composed of a phenol resin as a binder.

裏板４１は、図２に示すように、摩擦材４０よりも一回り大きく形成されて摩擦材４０が貼付される主板部４５と、この主板部４５のディスク回転方向両側のディスク半径方向の中間位置から、ディスク回転方向に沿って突出する一対の耳部４６とを有している。   As shown in FIG. 2, the back plate 41 is formed to be slightly larger than the friction material 40, and a main plate portion 45 to which the friction material 40 is attached, and an intermediate in the disk radial direction on both sides of the main plate portion 45 in the disk rotation direction. From the position, it has a pair of ear | edge part 46 which protrudes along a disk rotation direction.

なお、ブレーキパッド１０は、これら一対の耳部４６において、キャリア１２のディスク回転方向に沿って凹む一対の凹部４７に入れ子状に入り込み、これら一対の凹部４７に摺動可能に支持されることになる。また、ブレーキパッド１０は、ディスクロータ１５に接触することで生じる制動トルクを、耳部４６よりもディスク半径方向（図２の上下方向）内側および外側の当接面４８，４９にて、キャリア１２の凹部４７よりもディスク半径方向内側および外側のトルク受面５０，５１に伝達することになる。   The brake pad 10 is nested in a pair of recesses 47 recessed along the disk rotation direction of the carrier 12 in the pair of ears 46, and is slidably supported by the pair of recesses 47. Become. Further, the brake pad 10 applies braking torque generated by contacting the disc rotor 15 at the contact surfaces 48 and 49 on the inner side and the outer side of the ear portion 46 in the disc radial direction (vertical direction in FIG. 2). This is transmitted to the torque receiving surfaces 50 and 51 on the inner side and the outer side in the radial direction of the disk with respect to the concave portion 47.

図３に示すように、裏板４１の主板部４５のディスク回転方向（図３の左右方向）の中間範囲は、裏板４１の全厚さにおいて合成樹脂からなる樹脂部５２の一層構造となっている。これに対し、主板部４５のディスク回転方向両端側および一対の耳部４６は、厚さ方向の摩擦材４０側の合成樹脂からなる一対の樹脂部５３と、厚さ方向の摩擦材４０とは反対側の一対の金属製のパッドガイド部材５４とからなる二層構造となっている。   As shown in FIG. 3, the intermediate range of the main plate portion 45 of the back plate 41 in the disk rotation direction (left and right direction in FIG. 3) is a single layer structure of the resin portion 52 made of synthetic resin in the entire thickness of the back plate 41. ing. In contrast, the both ends of the main plate 45 in the disk rotation direction and the pair of ears 46 are composed of a pair of resin portions 53 made of synthetic resin on the friction material 40 side in the thickness direction and the friction material 40 in the thickness direction. It has a two-layer structure comprising a pair of metal pad guide members 54 on the opposite side.

樹脂部５２および一対の樹脂部５３が樹脂部材５５を構成している。樹脂部材５５は、摩擦材４０と同様のフェノール樹脂からなっており、摩擦材４０はその他面が全面的に樹脂部材５５に貼付されている。   The resin part 52 and the pair of resin parts 53 constitute a resin member 55. The resin member 55 is made of the same phenol resin as that of the friction material 40, and the other surface of the friction material 40 is adhered to the resin member 55 entirely.

パッドガイド部材５４は、鋼材からなるもので、主板部４５のディスク回転方向端側の一部を構成する主板部構成部５８と、図４に示すように、主板部構成部５８のディスク半径方向中間位置からディスク回転方向に沿って外側に突出して耳部４６を構成する耳部構成部５９とからなっている。また、樹脂部５３も同様の主板部構成部６０と耳部構成部６１とからなっている。ここで、パッドガイド部材５４の厚さは樹脂部５２の厚さよりも薄いものの、樹脂部５３の厚さよりは厚くなっている。   The pad guide member 54 is made of a steel material. As shown in FIG. 4, the main plate portion constituting portion 58 constituting a part of the main plate portion 45 on the disk rotation direction end side, and the main plate portion constituting portion 58 in the disk radial direction. It comprises an ear portion constituting portion 59 that protrudes outward from the intermediate position along the disk rotation direction and constitutes the ear portion 46. The resin portion 53 also includes a main plate portion constituting portion 60 and an ear portion constituting portion 61 that are similar to each other. Here, the thickness of the pad guide member 54 is thinner than the thickness of the resin portion 52, but is thicker than the thickness of the resin portion 53.

上記の樹脂部材５５と一対のパッドガイド部材５４とは、パッドガイド部材５４に樹脂部材５５をモールドすることで一体化されて裏板４１となる。なお、パッドガイド部材５４は、その厚さ方向一側の固着面６３の全面が、樹脂部５３の厚さ方向一側の固着面６４に固着される。また、パッドガイド部材５４は、そのディスク回転方向の耳部構成部５９とは反対側の固着面６５の全面が、樹脂部５２のディスク回転方向の端部の固着面６６に固着される。   The resin member 55 and the pair of pad guide members 54 are integrated by forming the resin member 55 on the pad guide member 54 to form the back plate 41. Note that the pad guide member 54 has its entire fixing surface 63 on one side in the thickness direction fixed to the fixing surface 64 on one side in the thickness direction of the resin portion 53. Further, the pad guide member 54 has its entire fixing surface 65 opposite to the ear rotation portion 59 in the disk rotation direction fixed to the fixing surface 66 at the end of the resin portion 52 in the disk rotation direction.

以上により、一対のパッドガイド部材５４は、相互間に樹脂部材５５の樹脂部５２を挟んで樹脂部材５５のディスク回転方向両端側にそれぞれ固着されており、ブレーキパッド１０は、一対のパッドガイド部材５４および一対の樹脂部５３からなる耳部４６においてキャリア１２に支持される。また、一対のパッドガイド部材５４は、一定の厚さとなっており、その全体が、樹脂部材５５の樹脂部５２よりも薄肉に形成され樹脂部材５５の樹脂部５３と肉厚方向に重なって固着される薄肉部となっている。   As described above, the pair of pad guide members 54 are fixed to both ends of the resin member 55 in the disk rotation direction with the resin portion 52 of the resin member 55 sandwiched therebetween, and the brake pad 10 is connected to the pair of pad guide members. 54 and an ear portion 46 including a pair of resin portions 53 are supported by the carrier 12. Further, the pair of pad guide members 54 have a constant thickness, and the whole is formed thinner than the resin portion 52 of the resin member 55, and overlaps with the resin portion 53 of the resin member 55 in the thickness direction. It has become a thin part.

以上に述べた第１実施形態によれば、一対の金属製のパッドガイド部材５４が、相互間に樹脂部材５５の樹脂部５２を挟んで樹脂部材５５のディスク回転方向両端側にそれぞれ固着されており、樹脂部材５５の樹脂部５２よりも薄肉に形成されているため、金属部分を小さくすることができ、軽量化を図ることができる。   According to the first embodiment described above, the pair of metal pad guide members 54 are respectively fixed to both ends of the resin member 55 in the disk rotation direction with the resin portion 52 of the resin member 55 interposed therebetween. And since it is formed thinner than the resin part 52 of the resin member 55, a metal part can be made small and weight reduction can be achieved.

また、一対のパッドガイド部材５４が、樹脂部材５５の樹脂部５３と肉厚方向に重なって固着されるため、ピストン２１および爪部２７の押圧力による剪断方向に交差する固着面６３，６４を有することになる。したがって、一対のパッドガイド部材５４が、ピストン２１および爪部２７の押圧力で樹脂部材５５から分離（つまり裏板４１が分解）してしまう可能性を低くできる。   Further, since the pair of pad guide members 54 are fixed to the resin portion 53 of the resin member 55 so as to overlap in the thickness direction, the fixing surfaces 63 and 64 intersecting the shearing direction due to the pressing force of the piston 21 and the claw portion 27 are formed. Will have. Therefore, the possibility that the pair of pad guide members 54 is separated from the resin member 55 by the pressing force of the piston 21 and the claw portion 27 (that is, the back plate 41 is disassembled) can be reduced.

また、一対のパッドガイド部材５４が、相互間に樹脂部材５５の樹脂部５２を挟んで樹脂部材５５のディスク回転方向両端側にそれぞれ固着されるため、ディスク回転方向に生じる制動トルクによる剪断方向に対して交差する固着面６５，６６を有することになる。したがって、一対のパッドガイド部材５４が、制動トルクで樹脂部材５５から分離（つまり裏板４１が分解）してしまう可能性を低くでき、信頼性を向上できる。   Further, since the pair of pad guide members 54 are respectively fixed to both ends of the resin member 55 in the disk rotation direction with the resin portion 52 of the resin member 55 sandwiched therebetween, in a shearing direction due to braking torque generated in the disk rotation direction. The fixing surfaces 65 and 66 intersect with each other. Therefore, the possibility that the pair of pad guide members 54 is separated from the resin member 55 by the braking torque (that is, the back plate 41 is disassembled) can be reduced, and the reliability can be improved.

なお、図５に示すように、パッドガイド部材５４の主板部構成部５８に厚さ方向に貫通する穴７０を形成し、図６に示すように、樹脂部材５５の樹脂部５３に穴７０に入り込む突起部７１を形成しても良い。あるいは、パッドガイド部材５４の主板部構成部５８に樹脂部５３側から凹む凹み部を形成し、樹脂部材５５にこの凹み部に入り込む突起部を形成しても良い。このように構成すれば、接着面積が増大することになり、パッドガイド部材５４が樹脂部材５５から分離してしまう可能性をさらに低くでき、信頼性をさらに向上できる。   As shown in FIG. 5, a hole 70 penetrating in the thickness direction is formed in the main plate portion constituting portion 58 of the pad guide member 54, and the hole 70 is formed in the resin portion 53 of the resin member 55 as shown in FIG. A protruding portion 71 may be formed. Alternatively, a recessed portion that is recessed from the resin portion 53 side may be formed in the main plate portion constituting portion 58 of the pad guide member 54, and a protruding portion that enters the recessed portion may be formed in the resin member 55. If comprised in this way, an adhesion area will increase and possibility that the pad guide member 54 will isolate | separate from the resin member 55 can further be reduced, and reliability can further be improved.

以上においては、パッドガイド部材５４が一定の厚さである場合を例にとり説明したが、一定の厚さでなくても、樹脂部材５５よりも薄肉に形成され樹脂部材５５と肉厚方向に重なって固着される薄肉部を有していれば良い。   In the above, the case where the pad guide member 54 has a constant thickness has been described as an example. However, even if the pad guide member 54 is not constant, it is formed thinner than the resin member 55 and overlaps the resin member 55 in the thickness direction. It suffices to have a thin-walled portion that is firmly attached.
