本考案は、自動車や自動二輪車等の車両に搭載されるディスクブレ―キであっ て、詳しくはこのディスクブレ―キに用いられる摩擦パッドとシム板との組付け 構造に関する。 This invention is applicable to disc brakes installed in vehicles such as automobiles and motorcycles. For details, see how to assemble the friction pad and shim plate used in this disc brake. Regarding structure.
【０００２】0002
ディスクロ―タの側面に配設された摩擦パッドを、制動時にピストンやキャリ パの反力爪等のパッド押動部材が押動すると、パッド押動部材がディスク軸方向 へ移動するの対し、摩擦パッドは、ディスクロ―タとの摺接によって、主として ディスク回転方向へ引摺られるため、ブレ―キ鳴きと呼ばれる異音を発生するこ とがある。このため、例えば実公平２―４４１０６号公報に示されるように、裏 板の背面にシム板を装着してこれを防止するようにした技術が知られている。 Friction pads placed on the side of the disc rotor are used to prevent pistons and carriers during braking. When the pad pushing member such as the reaction claw of the pad is pushed, the pad pushing member moves in the disk axial direction. In contrast, the friction pad mainly moves by sliding contact with the disc rotor. Because the disc is dragged in the direction of rotation, it may generate an abnormal noise called brake squeal. There is. For this reason, for example, as shown in Utility Model Publication No. 2-44106, A known technique is to prevent this by attaching a shim plate to the back of the plate.
【０００３】 この技術は、シム板を、裏板背面側の弾性材コ―ティングシムと、これを覆う 金属板との２枚構成とし、これらコ―ティングシムと金属板とに、それぞれ裏板 のディスク外周側とディスク内周側の側端面を挟持する弾性の係止片を突設する と共に、裏板のディスク外周側とディスク内周側の側端面のうち、少なくとも一 方の側端面に、コ―ティングシムと金属板の係止片をディスク回転方向に位置決 めする突起をディスク半径方向に突設している。0003 This technology covers the shim plate with an elastic material coating shim on the back side of the back plate. The coating shim and the metal plate each have a back plate. A protruding elastic locking piece is provided to sandwich the side end surfaces of the outer circumferential side of the disk and the inner circumferential side of the disk. Also, at least one of the side end surfaces of the back plate on the outer circumference side of the disk and the inner circumference side of the disk. Position the coating shim and the locking piece of the metal plate on the side end face in the direction of disk rotation. A protrusion for engaging the disc is provided protruding in the radial direction of the disc.
【０００４】0004
しかし、弾性材コ―ティングシムと金属板とに設けられる弾性の係止片は、弾 性とはいっても、その材質によってディスク半径方向に僅かな撓みを許容して、 裏板から弾性材コ―ティングシムや金属板が脱落しないようにしているに過ぎず 、裏板の突起との係合によって、摩擦パッドと弾性材コ―ティングシムと金属板 とを固定し、制動時にはこれら３者がディスク回転方向へ一体に移動するように したものであるから、パッド押動部材と当接して押動を受ける箇所が、旧来の裏 板から金属板に代えられたに過ぎない。 However, the elastic locking piece provided on the elastic material coating shim and the metal plate is However, depending on the material, a slight deflection in the disk radial direction is allowed, It merely prevents the elastic material coating shim and metal plate from falling off the back plate. , by engaging with the protrusions on the back plate, the friction pad, elastic material coating shim and metal plate and are fixed so that during braking, these three parts move together in the direction of disc rotation. Therefore, the part that comes into contact with the pad pushing member and receives the pushing force is different from the conventional backside. The plate was simply replaced with a metal plate.
【０００５】 従って、裏板外側の金属板が摩擦パッドと一体となって、ディスク軸方向へ移 動するパッド押動部材と擦り合いながら引摺られることに変りなく、しかも面積 の広い金属板を小面積のピストンや反力爪が当接するため、ブレ―キ鳴きが発生 し易くなり、またパッド押動部材先端の損耗も大きいという欠点がある。[0005] Therefore, the metal plate on the outside of the back plate is integrated with the friction pad and moves in the axial direction of the disc. There is no change in the fact that the pad is dragged while rubbing against the moving pad pushing member, and the area is small. Brake squeal occurs because the small-area piston and reaction claw come into contact with the wide metal plate. This has the disadvantage that it becomes easier to press the pad, and the tip of the pad pressing member is also subject to considerable wear and tear.
【０００６】 また、上述の係止片が、裏板の挟持とディスク回転方向の固定を兼ねているた め、一方の組付け性能が損われた場合には、他方の組付け性能にも影響を及ぼす という虞がある。[0006] In addition, the above-mentioned locking piece serves both to clamp the back plate and to fix the disk rotation direction. Therefore, if the assembly performance of one is impaired, it will affect the assembly performance of the other. There is a possibility that
【０００７】 本考案は、このような実情に鑑みてなされたもので、その目的とするところは 、制動時のブレ―キ鳴きを充分に防止しつつ、パッド当接部材先端の損耗を防ぐ と共に、確実な組付けを図った摩擦パッドとシム板の組付け構造を提供すること にある。[0007] This invention was developed in view of these circumstances, and its purpose is to , sufficiently prevents brake squeal during braking and prevents wear and tear on the tip of the pad contact member. In addition, to provide a structure for assembling a friction pad and a shim plate that ensures reliable assembly. It is in.

上述の目的に従い、本考案は、摩擦パッドの裏板背面に、該裏板のディスク外 周側とディスク内周側の側端面を係止片で挟持してシム板を組付ける車両用ディ スクブレ―キの摩擦パッドとシム板の組付け構造において、前記裏板の背面両側 部にストッパを形成し、前記シム板に、前記裏板のストッパと当接して、摩擦パ ッドとシム板とのディスク回転方向の相対偏位を許容する一対の弾性係止部を設 けたことを特徴とするものである。 In accordance with the above-mentioned purpose, the present invention provides a friction pad with a disc outer part on the back side of the back plate of the friction pad. A vehicle disc in which a shim plate is assembled by holding the side end faces of the circumferential side and the inner circumferential side of the disc with locking pieces. In the assembly structure of the scrub brake friction pad and shim plate, both sides of the back of the back plate A stopper is formed on the shim plate, and the shim plate contacts the stopper on the back plate to form a friction pad. A pair of elastic locking parts are provided to allow relative deviation in the disk rotation direction between the head and the shim plate. It is characterized by a large number of characters.
【０００９】[0009]
摩擦パッドがディスクロ―タと摺接した場合に、摩擦パッドにはディスクロ― タの引摺りトルクがかかるが、シム板には、パッド押動部材の押圧力がかかって 現状位置を確保しようとするので、両者の間にズレ力を生じる。これにより、摩 擦パッドはシム板を残したまま、シム板の弾性係止部を撓ませながらディスク回 転方向へ移動する。シム板はパッド押動部材に対して殆どズレないかズレても極 僅かな量であって、シム板とパッド押動部材先端との面積差が大きい場合にも、 ブレ―キ鳴きが生じにくくなり、またシム板と接触するパッド押動部材先端の損 耗も起きにくい。 When the friction pad comes into sliding contact with the disc rotor, the friction pad has a disc rotor. However, the pushing force of the pad pushing member is applied to the shim plate. Since they try to secure their current position, a displacement force is generated between the two. This allows For the friction pad, leave the shim plate in place and rotate the disc while bending the elastic locking part of the shim plate. move in the direction of rotation. The shim plate does not shift with respect to the pad pushing member, or even if it does, it does not shift at all. Even if the difference in area between the shim plate and the tip of the pad pushing member is small, but there is a large difference in area, Brake squeal is less likely to occur, and damage to the tip of the pad pushing member that comes into contact with the shim plate is reduced. Less likely to wear out.

【００１６】 上述のように形成されたシム板１２は、板体１２ａを裏板１１の背面１１ｂに 密着させ、上縁の係止片１２ｂを、ディスク外周側の側端面１１ｃの中央に係止 し、下縁の係止片１２ｃ，１２ｃを、ディスク内周側の側端面１１ｄに係止して 裏板１１を挟持し、更に側縁の弾性係止部１２ｄ，１２ｄを、ストッパ１１ｇ， １１ｇの内側に配置して、各爪片１２ｆをストッパ１１ｇの対向面に当接させて 組付けられる。[0016] The shim plate 12 formed as described above has the plate body 12a on the back surface 11b of the back plate 11. the upper edge of the locking piece 12b to the center of the side end surface 11c on the outer peripheral side of the disk. Then, lock the lower edge locking pieces 12c, 12c to the side end surface 11d on the inner peripheral side of the disk. The back plate 11 is held between the elastic locking portions 12d, 12d on the side edges, and the stoppers 11g, 11g, and each claw piece 12f is brought into contact with the opposing surface of the stopper 11g. Can be assembled.
【００１７】 このようにして裏板１１に組付けられたシム板１２は、裏板１１のディスク内 外周側の側端面１１ｃ，１１ｄを係止片１２ｂ，１２ｃ，１２ｃで挟持するため 、ディスク半径方向には移動を規制されるが、ストッパ１１ｇ，１１ｇの内側に 配置される弾性係止部１２ｄ，１２ｄのＵ字状弾性部１２ｅ，１２ｅが横方向の 弾性力を持つので、摩擦パッド８に対して相対偏位可能に取付けられる。[0017] The shim plate 12 assembled to the back plate 11 in this way is inserted into the disc of the back plate 11. To clamp the outer peripheral side end surfaces 11c and 11d with the locking pieces 12b, 12c, and 12c. , movement is restricted in the disk radial direction, but inside the stoppers 11g, 11g. The U-shaped elastic portions 12e, 12e of the elastic locking portions 12d, 12d are arranged in the horizontal direction. Since it has elastic force, it can be attached to the friction pad 8 so that it can be displaced relative to the friction pad 8.
【００１８】 摩擦パッド８はこのようにして、裏板１１にシム板１２を組付けしてキャリパ ボディ２に装着され、制動操作によって摩擦パッド８がディスクロ―タ５に摺接 すると、摩擦パッド８とシム板１２にディスクロ―タ５の引摺りトルクがかかる が、シム板１２には、ピストン７や反力爪２ｄの押圧力がかかって現状位置を保 とうとするため、裏板１１とシム板１２との間にズレ力を生じる。これにより、 ディスク回入側のストッパ１１ｇが、これと当接する弾性係止部１２ｂのＵ字状 弾性部１２ｅを圧縮しながら、摩擦パッド８が、シム板１２を残してディスク回 転方向へ移動する。[0018] In this way, the friction pad 8 is attached to the caliper by assembling the shim plate 12 to the back plate 11. Attached to the body 2, the friction pad 8 slides into contact with the disc rotor 5 during braking operation. Then, the drag torque of the disc rotor 5 is applied to the friction pad 8 and the shim plate 12. However, the shim plate 12 maintains its current position due to the pressing force of the piston 7 and the reaction claw 2d. As a result, a shearing force is generated between the back plate 11 and the shim plate 12. This results in The stopper 11g on the disk rotation side contacts the U-shaped elastic locking portion 12b. While compressing the elastic portion 12e, the friction pad 8 rotates the disk leaving the shim plate 12. move in the direction of rotation.
【００１９】 次に、この制動操作を解除すると、引摺りトルクの解消で原形に復元するディ スク回入側の弾性係止部１２ｄのＵ字状弾性部１２ｅが、裏板１１のストッパ１ １ｇを押し戻し、摩擦パッド８を制動時とは逆方向へ移動させて、制動前の無負 荷位置に復帰させる。[0019] Next, when this braking operation is released, the drag torque is removed and the disk returns to its original shape. The U-shaped elastic portion 12e of the elastic locking portion 12d on the insertion side Push back 1g, move the friction pad 8 in the opposite direction to the direction used during braking, and remove the negative force before braking. Return to loaded position.
【００２０】 本実施例はこのように、ピストン７や反力爪２ｄ等のパッド押動部材に押圧さ れるシム板１２が、ピストン７や反力爪２ｄから殆どズレないか、ズレたとして も極僅かな量で済むので、シム板１２とピストン７や反力爪２ｄの先端との面積 差が大きい場合にも、ブレ―キ鳴きが発生しにくくなり、またシム板１２と当接 するピストン７や反力爪２ｄの先端の損耗も起きにくくなる。[0020] In this embodiment, the pad is pressed by a pad pushing member such as the piston 7 or the reaction claw 2d. The shim plate 12, which is attached to the Since only a very small amount is required, the area between the shim plate 12 and the tip of the piston 7 and the reaction claw 2d Even if the difference is large, brake squeal is less likely to occur, and contact with the shim plate 12 is reduced. The piston 7 and the tips of the reaction claws 2d are less likely to be worn out.
【００２１】 更に、シム板１２の弾性係止部１２ｄが、制動時には摩擦パッド８とキャリパ ボディ２のトルク受け部との当接をやわらげて当接音の発生を防止し、また制動 解除時には、摩擦パッド８を制動前の無負荷位置へ強制的に復帰させるので、ラ イニング１０をディスクロ―タ５に引摺る虞が少なくなる。[0021] Furthermore, the elastic locking portion 12d of the shim plate 12 engages the friction pad 8 and the caliper during braking. It softens the contact with the torque receiving part of the body 2 to prevent contact noise and also prevents braking. When the brake is released, the friction pad 8 is forcibly returned to the no-load position before braking, so the brake There is less risk of the inning 10 being dragged by the disc rotor 5.
【００２２】 また、本実施例の裏板１１とシム板１２との組付けでは、ディスク半径方向の 組付けを係止片１２ｂ，１２ｃ，１２ｃが担い、更にディスク回転方向の組付け を、これとは別個の弾性係止部１２ｄ，１２ｄが担うようにしたから、一方の組 付け性能が損われることがあっても、他方の組付け性能に影響を及ぼすことがな くなり、組付けに対する高い信頼性が得られる。[0022] In addition, when assembling the back plate 11 and shim plate 12 of this embodiment, the direction of the disk radial direction is The locking pieces 12b, 12c, 12c are responsible for the assembly, and also the assembly in the disk rotation direction. is handled by separate elastic locking parts 12d, 12d, so one set Even if the assembly performance may be impaired, it will not affect the assembly performance of the other. This results in high assembly reliability.
【００２３】 尚、上述の実施例では、シム板の弾性係止部をストッパの対向面に当接させた が、弾性係止部をストッパの外側を跨ぐ形状に形成して、弾性係止部をストッパ の反対向面に当接させるようにしてもよい。また、ストッパを凹溝に形成して、 弾性係止部を凹溝内に当接係合させることもできる。[0023] In the above embodiment, the elastic locking portion of the shim plate was brought into contact with the opposing surface of the stopper. However, the elastic locking portion is formed in a shape that straddles the outside of the stopper, and the elastic locking portion is connected to the stopper. It may be made to abut on the opposite surface of. In addition, the stopper is formed in a concave groove, It is also possible to abut and engage the elastic locking portion within the groove.

本考案は以上のように、摩擦パッドの裏板の背面両側部にストッパを形成し、 該裏板の背面に組付けられるシム板に、裏板のディスク外周側とディスク内周側 の両側端面を挟持する係止片と、前記裏板のストッパと当接して、摩擦パッドと シム板とのディスク回転方向の相対偏位を許容する一対の弾性係止部を設けたか ら、制動時には摩擦パッドのみがディスク回転方向へ移動するだけで、ピストン や反力爪等のパッド押動部材に押圧されるシム板は、パッド押動部材から殆どズ レないか、ズレたとしても極僅かな量であるから、シム板とパッド押動部材の先 端との面積差が大きい場合にも、ブレ―キ鳴きが発生しにくくなり、またシム板 と当接するパッド押動部材先端の損耗も起きにくくなる。 As described above, the present invention forms stoppers on both sides of the back of the back plate of the friction pad, The outer circumferential side of the disk and the inner circumferential side of the disk of the back plate are attached to the shim plate assembled on the back of the back plate. A locking piece that clamps both end surfaces of the friction pad comes into contact with the stopper of the back plate, and the friction pad and Are there a pair of elastic locking parts that allow relative deviation in the direction of disk rotation with the shim plate? During braking, only the friction pad moves in the direction of disk rotation, and the piston The shim plate that is pressed by the pad pushing member such as the pad pushing member such as the The tip of the shim plate and pad pushing member should be Brake squeal is less likely to occur even when there is a large area difference between the edges and the shim plate. The tip of the pad pushing member that comes into contact with the pad is less likely to be worn out.
【００２５】 更に、シム板の弾性係止部が、制動時には摩擦パッドとキャリパのトルク受け 部との当接をやわらげて当接音の発生を防止し、また制動解除時には、摩擦パッ ドを制動前の無負荷位置に復帰させて、ライニングをディスクロ―タに引摺る虞 が少なくなる。[0025] Furthermore, the elastic locking part of the shim plate absorbs the torque of the friction pad and caliper during braking. It softens the contact with the parts and prevents contact noise, and also uses friction pads when releasing the brake. There is a risk of the lining being dragged by the disc rotor by returning the disc to its unloaded position before braking. becomes less.
【００２６】 また、裏板にシム板を組付ける場合に、ディスク半径方向の組付けを係止片が 担い、更にディスク回転方向の組付けを、これとは別個の弾性係止部が担うよう にしたから、一方の組付け性能が損われることがあっても、他方の組付け性能に 影響を及ぼすことがないので、組付けに対する信頼性が高い。[0026] Also, when assembling the shim plate to the back plate, the locking piece prevents the assembly in the radial direction of the disc. In addition, a separate elastic locking part is responsible for the assembly in the disk rotation direction. Therefore, even if the assembly performance of one side is impaired, the performance of the other side will not be affected. Since there is no influence, the reliability of assembly is high.
