Description
本発明は、ディスクブレーキ用摩擦パッド組立て体に関する。
The present invention relates to a friction pad assembly for a disc brake.
例えば鉄道車両用のディスクブレーキ装置は、車軸に固定されるディスクロータと、このディスクロータに対峙して配置されるトルク受けプレートのディスクロータ側の面にライニング組立体を組み付けたディスクブレーキ用摩擦パッド組立て体と、トルク受けプレートをディスクロータに向かって進退駆動するアクチュエータを内蔵して車体フレームに固定されるブレーキキャリパとを備える。ディスクブレーキ装置は、トルク受けプレートをディスクロータ側に進出させてライニング組立体がディスクロータへ押圧された時の摺動摩擦によって制動力を発生する。
For example, a disc brake device for a railway vehicle includes a disc rotor fixed to an axle, and a disc brake friction pad in which a lining assembly is assembled on a disc rotor side surface of a torque receiving plate arranged to face the disc rotor. The assembly includes a brake caliper that includes an actuator that drives the torque receiving plate to advance and retract toward the disc rotor and is fixed to the vehicle body frame. The disc brake device generates a braking force by sliding friction when the torque receiving plate is advanced to the disc rotor side and the lining assembly is pressed against the disc rotor.
ところで、上記ディスクブレーキ装置は、ディスクロータとの接触によってライニング組立体が不用意に回転すると、それにより制動トルクの伝達にロスが発生したり、ブレーキノイズが発生したりするため、ライニング組立体の回転を規制する回転防止機構(回り止め構造)が必要になる。特許文献1に開示されるディスクブレーキ用摩擦パッド組立て体は、ライニング組立体を揺動自在に支持するガイドプレートの内面とバックプレート(トルク受けプレート)の内面との間に回転規制板を固定し、該回転規制板を裏板部の抜け止めフランジに係合させることでライニング組立体の回転を規制する回転防止機構を構成している。
By the way, in the above-described disc brake device, if the lining assembly rotates carelessly due to contact with the disc rotor, this causes loss of transmission of braking torque or brake noise. An anti-rotation mechanism (anti-rotation structure) that restricts rotation is required. In the friction pad assembly for a disc brake disclosed in Patent Document 1, a rotation restricting plate is fixed between an inner surface of a guide plate that supports the lining assembly in a swingable manner and an inner surface of a back plate (torque receiving plate). The rotation restricting plate is engaged with the retaining flange of the back plate portion to constitute a rotation preventing mechanism for restricting the rotation of the lining assembly.
しかしながら、上記特許文献1に開示された回転防止機構のように、ガイドプレートの内面とトルク受けプレートの内面との間に回転規制板を固定した場合には、部品点数及び重量が増え、製作コストも増大した。
また、ライニング組立体を揺動自在に支持するため、バックプレートに当接する当接曲面部を裏板部や嵌着板に突出して形成した場合には、切削加工が必要となり加工コストが増えたり、部品点数が増えたりして製作コストが増大する。 However, when the rotation restricting plate is fixed between the inner surface of the guide plate and the inner surface of the torque receiving plate as in the rotation preventing mechanism disclosed inPatent Document 1, the number of parts and the weight increase, and the manufacturing cost is increased. Also increased.
In addition, in order to support the lining assembly in a swingable manner, if the abutting curved surface portion that abuts the back plate protrudes from the back plate portion or the fitting plate, cutting is necessary, which increases the processing cost. The production cost increases due to an increase in the number of parts.

The production cost increases due to an increase in the number of parts.

1 is a front view of a
The
トルク受けプレート11は、ライニング組立体15を挿入装着したガイドプレート13に取り付けられる。トルク受けプレート11は、ライニング組立体15の裏板部17との間に間隙S1を開けて、リベット19によりガイドプレート13に固着される。トルク受けプレート11は、裏板部17との間に間隙S1を開けるため、裏板部17の背面側を覆う薄皿状に成形されている。
The torque receiving plate 11 is attached to the guide plate 13 on which the lining assembly 15 is inserted and mounted. The torque receiving plate 11 is fixed to the guide plate 13 by a rivet 19 with a gap S1 provided between the torque receiving plate 11 and the back plate portion 17 of the lining assembly 15. The torque receiving plate 11 is formed in a thin dish shape covering the back side of the back plate portion 17 in order to open a gap S <b> 1 with the back plate portion 17.
トルク受けプレート11の裏面11aには、図2及び図3に示すように、アンカープレート21がリベット23により固定装備されている。このアンカープレート21が、アクチュエータ(図示略)に連結されたキャリパーの押圧ホルダー25に連結される。これにより、摩擦パッド組立て体100は、ディスクロータへの進退駆動が可能になる。
As shown in FIGS. 2 and 3, an anchor plate 21 is fixedly mounted on the back surface 11 a of the torque receiving plate 11 with a rivet 23. The anchor plate 21 is connected to a caliper pressing holder 25 connected to an actuator (not shown). Thereby, the friction pad assembly 100 can be driven back and forth to the disk rotor.
ガイドプレート13は、図1に示すように、ガイド孔部27が所定の離間間隔で複数(5孔)形成されており、各ガイド孔部27にライニング組立体15が装着される。ガイドプレート13は、制動時に各ガイド孔部27に装着されたライニング組立体15に作用する制動トルクを受け止めることができる所定の板厚を有した平板材で形成される。
As shown in FIG. 1, a plurality of guide hole portions 27 (five holes) are formed in the guide plate 13 at predetermined spacing intervals, and the lining assembly 15 is attached to each guide hole portion 27. The guide plate 13 is formed of a flat plate material having a predetermined plate thickness capable of receiving a braking torque that acts on the lining assembly 15 mounted in each guide hole 27 during braking.
ライニング組立体15は、制動トルクを受けるガイドプレート13に揺動自在に支持されて、ディスクロータへ押圧される。ライニング組立体15は、略円板状に成型された摩擦材29と、この摩擦材29の裏面に固着された裏板部17とから構成されている。裏板部17には、外周面がガイドプレート13に貫通形成された円形のガイド孔部27に揺動自在に嵌合するプレート嵌合部31と、ガイド孔部27よりも大きな外径の抜け止めフランジ部33と、が一体形成されている。
The lining assembly 15 is swingably supported by the guide plate 13 that receives the braking torque, and is pressed against the disk rotor. The lining assembly 15 includes a friction material 29 formed in a substantially disc shape, and a back plate portion 17 fixed to the back surface of the friction material 29. The back plate portion 17 includes a plate fitting portion 31 that slidably fits in a circular guide hole portion 27 whose outer peripheral surface is formed through the guide plate 13, and an outer diameter that is larger than that of the guide hole portion 27. The stop flange portion 33 is integrally formed.
摩擦材29は、ガイド孔部27を挿通可能なように、外径がガイド孔部27の内径よりも小さく設定されている。摩擦材29は、制動時にディスクロータに押圧される。ライニング組立体15は、プレート嵌合部31がガイド孔部27に嵌合されていることで、ディスクロータに摩擦材29が押圧された時に作用する制動トルクをプレート嵌合部31からガイドプレート13に伝達する。
The outer diameter of the friction material 29 is set smaller than the inner diameter of the guide hole 27 so that the guide hole 27 can be inserted. The friction material 29 is pressed against the disk rotor during braking. In the lining assembly 15, the plate fitting portion 31 is fitted in the guide hole portion 27, so that the braking torque acting when the friction material 29 is pressed against the disk rotor is applied from the plate fitting portion 31 to the guide plate 13. To communicate.
プレート嵌合部31は、ガイド孔部27との摺接によるライニング組立体15の揺動動作が円滑になるように、ガイド孔部27側に凸の曲面状に形成されている。これにより、プレート嵌合部31は、ガイドプレート13に設けられたガイド孔部27に揺動自在に嵌合される。
The plate fitting portion 31 is formed in a convex curved shape on the guide hole 27 side so that the swinging motion of the lining assembly 15 by sliding contact with the guide hole 27 is smooth. Thereby, the plate fitting part 31 is fitted in the guide hole part 27 provided in the guide plate 13 so that rocking is possible.
プレート嵌合部31には、環状のバネ部材35が嵌着される。バネ部材35は、円環状の板ばねよりなる。バネ部材35の外径は、ガイド孔部27よりも大きく設定されている。各ライニング組立体15は、ガイドプレート13の裏面側からガイド孔部27に挿入装着される。従って、プレート嵌合部31に嵌着されたバネ部材35は、ガイドプレート13と抜け止めフランジ部33との間に挟まれる。
An annular spring member 35 is fitted to the plate fitting portion 31. The spring member 35 is an annular leaf spring. The outer diameter of the spring member 35 is set larger than that of the guide hole portion 27. Each lining assembly 15 is inserted and attached to the guide hole 27 from the back side of the guide plate 13. Accordingly, the spring member 35 fitted to the plate fitting portion 31 is sandwiched between the guide plate 13 and the retaining flange portion 33.
摩擦パッド組立て体100は、複数個のライニング組立体15を平面状に敷き並べた形態となる。摩擦パッド組立て体100は、ライニング組立体15の抜け止めフランジ部33とガイドプレート13との間に挟まれたバネ部材35が、弾性変形してライニング組立体15の厚さ方向の寸法公差を吸収する。このため、摩擦パッド組立て体100では、ディスクロータに対する各ライニング組立体15の接触性にばらつきの生じることが防止される。従って、各ライニング組立体15は、厚さ方向の寸法公差の影響を受けずに、安定した制動特性を維持することができる。
The friction pad assembly 100 has a form in which a plurality of lining assemblies 15 are arranged in a plane. In the friction pad assembly 100, the spring member 35 sandwiched between the retaining flange portion 33 of the lining assembly 15 and the guide plate 13 is elastically deformed to absorb the dimensional tolerance in the thickness direction of the lining assembly 15. To do. For this reason, in the friction pad assembly 100, it is possible to prevent variation in the contact property of each lining assembly 15 with respect to the disk rotor. Therefore, each lining assembly 15 can maintain stable braking characteristics without being affected by dimensional tolerance in the thickness direction.
ところで、ガイドプレート13に固着されたトルク受けプレート11には、ライニング組立体15の回転を規制する回り止め規制部が一体形成されている。
本第1実施形態において、回り止め規制部は、切り起し片37よりなる。切り起し片37は、裏板部17に形成された係止凹部39に係合するように、トルク受けプレート11に形成される。切り起し片37は、トルク受けプレート11をU字形のポンチ等で打ち抜き、U字形スリットを形成した後、このU字形スリットに包囲された板片の基端を、図4に示すように、裏板部17に向かってトルク受けプレート11に対し垂直に折り曲げる(切り起す)ことにより形成される。 By the way, thetorque receiving plate 11 fixed to the guide plate 13 is integrally formed with an anti-rotation restricting portion for restricting the rotation of the lining assembly 15.
In the first embodiment, the anti-rotation restricting portion includes a cut and raisedpiece 37. The cut-and-raised piece 37 is formed on the torque receiving plate 11 so as to engage with a locking recess 39 formed on the back plate portion 17. The cut-and-raised piece 37 is formed by punching the torque receiving plate 11 with a U-shaped punch or the like to form a U-shaped slit, and then, as shown in FIG. 4, the base end of the plate piece surrounded by the U-shaped slit is as shown in FIG. It is formed by bending (cutting up) perpendicularly to the torque receiving plate 11 toward the back plate portion 17.
本第1実施形態において、回り止め規制部は、切り起し片37よりなる。切り起し片37は、裏板部17に形成された係止凹部39に係合するように、トルク受けプレート11に形成される。切り起し片37は、トルク受けプレート11をU字形のポンチ等で打ち抜き、U字形スリットを形成した後、このU字形スリットに包囲された板片の基端を、図4に示すように、裏板部17に向かってトルク受けプレート11に対し垂直に折り曲げる(切り起す)ことにより形成される。 By the way, the
In the first embodiment, the anti-rotation restricting portion includes a cut and raised
切り起し片37は、裏板部17に形成される係止凹部39に係合して、ライニング組立体15の回転を規制する。本第1実施形態において、係止凹部39は、裏板部17に穿設した穴である。なお、係止凹部39は、穴に限定されない。
The cut-and-raised piece 37 engages with a locking recess 39 formed in the back plate portion 17 to restrict the rotation of the lining assembly 15. In the first embodiment, the locking recess 39 is a hole formed in the back plate portion 17. Note that the locking recess 39 is not limited to a hole.
例えば係止凹部39は、円形状の裏板部17の円周方向の2点を結ぶ直線(弦)で切除した凹みであってもよい。この凹みは、裏板部17の外周が、半径方向内側に凹む係止凹部39となる。切り起し片37は、この凹みから成る係止凹部39に当接することによってもライニング組立体15の回転を規制することができる。
For example, the locking recess 39 may be a recess cut by a straight line (string) connecting two points in the circumferential direction of the circular back plate portion 17. This recess serves as a locking recess 39 whose outer periphery of the back plate portion 17 is recessed inward in the radial direction. The cut-and-raised piece 37 can also restrict the rotation of the lining assembly 15 by abutting against a locking recess 39 made of this recess.
また、本第1実施形態に係る摩擦パッド組立て体100では、トルク受けプレート11に、裏板部17に向かって突出する凸部41が形成されている。凸部41は、例えばプレス加工により形成することができる。この凸部41は、ライニング組立体15を揺動可能に支持する。凸部41により円形状の裏板部17の中心部分が支持されたライニング組立体15は、凸部41を中心に揺動自在(ピボット運動自在)に支持される。
Further, in the friction pad assembly 100 according to the first embodiment, the torque receiving plate 11 is formed with a convex portion 41 protruding toward the back plate portion 17. The convex portion 41 can be formed by, for example, pressing. The convex portion 41 supports the lining assembly 15 so as to be swingable. The lining assembly 15 in which the central portion of the circular back plate portion 17 is supported by the convex portion 41 is supported so as to be swingable (pivotable) around the convex portion 41.
図5はキャリパーにおける押圧ホルダー25のブレーキパッド取付部43に取り付けられた図1に示す摩擦パッド組立て体100の断面図である。
摩擦パッド組立て体100は、図5に示すように、キャリパーの押圧ホルダー25に取り付けられる。摩擦パッド組立て体100のトルク受けプレート11の裏面11aには、アンカープレート21がリベット23によって固定される。摩擦パッド組立て体100は、このアンカープレート21が、キャリパーの押圧ホルダー25におけるブレーキパッド取付部43(押圧ホルダー25のディスクロータ側取付面)に形成された蟻溝状の固定溝45に、溝端から挿入されることにより取り付けられる。 5 is a cross-sectional view of thefriction pad assembly 100 shown in FIG. 1 attached to the brake pad attachment portion 43 of the press holder 25 in the caliper.
As shown in FIG. 5, thefriction pad assembly 100 is attached to the caliper pressing holder 25. An anchor plate 21 is fixed to the back surface 11 a of the torque receiving plate 11 of the friction pad assembly 100 by a rivet 23. In the friction pad assembly 100, the anchor plate 21 is inserted into the dovetail-shaped fixing groove 45 formed on the brake pad mounting portion 43 (the mounting surface on the disk rotor side of the pressing holder 25) from the end of the groove. It is attached by being inserted.
摩擦パッド組立て体100は、図5に示すように、キャリパーの押圧ホルダー25に取り付けられる。摩擦パッド組立て体100のトルク受けプレート11の裏面11aには、アンカープレート21がリベット23によって固定される。摩擦パッド組立て体100は、このアンカープレート21が、キャリパーの押圧ホルダー25におけるブレーキパッド取付部43(押圧ホルダー25のディスクロータ側取付面)に形成された蟻溝状の固定溝45に、溝端から挿入されることにより取り付けられる。 5 is a cross-sectional view of the
As shown in FIG. 5, the
摩擦パッド組立て体100は、トルク受けプレート11の裏面11aが、このキャリパーの押圧ホルダー25のブレーキパッド取付部43に密着する。トルク受けプレート11の裏面11aには、複数の開口47が開けられている。この開口47は、切り起し片37を形成するために打ち抜いたU字形スリットにおいて切り起し片37を切り起こした後の方形の開口である。なお、開口47は、切り起し片37の形状に応じて種々の開口形状を有する。トルク受けプレート11は、裏面11aにおける開口47の開口周縁がブレーキパッド取付部43に密着することにより、これら開口47がブレーキパッド取付部43により塞がれる。これにより、トルク受けプレート11の裏面側から異物が開口47を通って、ガイドプレート13との間に進入することが確実に抑制されている。
In the friction pad assembly 100, the back surface 11a of the torque receiving plate 11 is in close contact with the brake pad mounting portion 43 of the pressing holder 25 of the caliper. A plurality of openings 47 are formed in the back surface 11 a of the torque receiving plate 11. This opening 47 is a rectangular opening after the cut and raised piece 37 is cut and raised in the U-shaped slit punched out to form the cut and raised piece 37. The opening 47 has various opening shapes depending on the shape of the cut and raised piece 37. In the torque receiving plate 11, the opening periphery of the opening 47 in the back surface 11 a is in close contact with the brake pad mounting portion 43, so that the opening 47 is closed by the brake pad mounting portion 43. Thereby, it is reliably suppressed that foreign matter enters the guide plate 13 from the back surface side of the torque receiving plate 11 through the opening 47.
次に、本第1実施形態に係る摩擦パッド組立て体100の組立手順を説明する。
摩擦パッド組立て体100を組み立てるには、先ず、背面を上方に向けてセットされたガイドプレート13のガイド孔部27に、摩擦材29をガイドプレート13の正面側(図3の左側)に突出するようにしてライニング組立体15が挿入装着される。この際、それぞれのライニング組立体15のプレート嵌合部31には、バネ部材35を嵌着しておく。ガイド孔部27にライニング組立体15が挿入されることで、バネ部材35は、ガイドプレート13と抜け止めフランジ部33との間に挟まれるようになる。ガイド孔部27に挿入装着されたライニング組立体15は、抜け止めフランジ部33が、バネ部材35を介してガイド孔部27の周縁部に当接した状態となる。 Next, the assembly procedure of thefriction pad assembly 100 according to the first embodiment will be described.
In order to assemble thefriction pad assembly 100, first, the friction material 29 is projected to the front side of the guide plate 13 (left side in FIG. 3) in the guide hole portion 27 of the guide plate 13 set with the back surface facing upward. In this way, the lining assembly 15 is inserted and mounted. At this time, the spring member 35 is fitted into the plate fitting portion 31 of each lining assembly 15. By inserting the lining assembly 15 into the guide hole portion 27, the spring member 35 is sandwiched between the guide plate 13 and the retaining flange portion 33. The lining assembly 15 inserted and mounted in the guide hole portion 27 is in a state where the retaining flange portion 33 is in contact with the peripheral edge portion of the guide hole portion 27 via the spring member 35.
摩擦パッド組立て体100を組み立てるには、先ず、背面を上方に向けてセットされたガイドプレート13のガイド孔部27に、摩擦材29をガイドプレート13の正面側(図3の左側)に突出するようにしてライニング組立体15が挿入装着される。この際、それぞれのライニング組立体15のプレート嵌合部31には、バネ部材35を嵌着しておく。ガイド孔部27にライニング組立体15が挿入されることで、バネ部材35は、ガイドプレート13と抜け止めフランジ部33との間に挟まれるようになる。ガイド孔部27に挿入装着されたライニング組立体15は、抜け止めフランジ部33が、バネ部材35を介してガイド孔部27の周縁部に当接した状態となる。 Next, the assembly procedure of the
In order to assemble the
全てのライニング組立体15をガイド孔部27に装着した状態で、トルク受けプレート11をガイドプレート13の上に載置する。この際、トルク受けプレート11には、アンカープレート21をリベット23によって固定しておく。トルク受けプレート11とガイドプレート13が合わせられると、トルク受けプレート11から突出する凸部41が、ライニング組立体15の裏板部17に当接する。同時に、トルク受けプレート11の切り起し片37が、裏板部17の係止凹部39に係合される。最後に、ガイドプレート13とトルク受けプレート11の外周部が、相互を貫通するリベット19によって、挟持固定され、ディスクブレーキ用摩擦パッド組立て体の組み立てが完了する。ガイドプレート13とトルク受けプレート11がリベット19によって固定された摩擦パッド組立て体100は、バネ部材35が所定の予圧で変形して、ガイドプレート13と抜け止めフランジ部33との間に挟持された状態となる。
The torque receiving plate 11 is placed on the guide plate 13 with all the lining assemblies 15 mounted in the guide holes 27. At this time, the anchor plate 21 is fixed to the torque receiving plate 11 with rivets 23. When the torque receiving plate 11 and the guide plate 13 are combined, the convex portion 41 protruding from the torque receiving plate 11 comes into contact with the back plate portion 17 of the lining assembly 15. At the same time, the cut-and-raised piece 37 of the torque receiving plate 11 is engaged with the locking recess 39 of the back plate portion 17. Finally, the outer peripheral portions of the guide plate 13 and the torque receiving plate 11 are clamped and fixed by the rivets 19 penetrating each other, and the assembly of the disc brake friction pad assembly is completed. In the friction pad assembly 100 in which the guide plate 13 and the torque receiving plate 11 are fixed by the rivet 19, the spring member 35 is deformed by a predetermined preload, and is sandwiched between the guide plate 13 and the retaining flange portion 33. It becomes a state.
次に、上記した構成の作用を説明する。
本第1実施形態に係る摩擦パッド組立て体100では、ライニング組立体15の回転を規制するための回り止め規制部である切り起し片37が、トルク受けプレート11に一体形成される。トルク受けプレート11に一体形成された切り起し片37は、ライニング組立体15の係止凹部39に係合し、ライニング組立体15の回転を規制する。このように、ライニング組立体15とトルク受けプレート11の間に、回り止め規制部である切り起し片37が直接配置されることにより、ライニング組立体15の回り止め構造を少ない部品点数で、簡素な構造にできる。 Next, the operation of the above configuration will be described.
In thefriction pad assembly 100 according to the first embodiment, a cut-and-raised piece 37 that is a rotation preventing restricting portion for restricting the rotation of the lining assembly 15 is formed integrally with the torque receiving plate 11. The cut-and-raised piece 37 formed integrally with the torque receiving plate 11 engages with the locking recess 39 of the lining assembly 15 and restricts the rotation of the lining assembly 15. In this way, by arranging the cut-and-raised piece 37, which is the anti-rotation restricting portion, directly between the lining assembly 15 and the torque receiving plate 11, the anti-rotation structure of the lining assembly 15 is reduced in the number of parts. It can be a simple structure.
本第1実施形態に係る摩擦パッド組立て体100では、ライニング組立体15の回転を規制するための回り止め規制部である切り起し片37が、トルク受けプレート11に一体形成される。トルク受けプレート11に一体形成された切り起し片37は、ライニング組立体15の係止凹部39に係合し、ライニング組立体15の回転を規制する。このように、ライニング組立体15とトルク受けプレート11の間に、回り止め規制部である切り起し片37が直接配置されることにより、ライニング組立体15の回り止め構造を少ない部品点数で、簡素な構造にできる。 Next, the operation of the above configuration will be described.
In the
また、本第1実施形態の摩擦パッド組立て体100では、ライニング組立体15を揺動自在に支持するためトルク受けプレート11に配置された凸部41が、ライニング組立体15の裏板部17に当接し、ライニング組立体15を揺動自在とすることができる。
Further, in the friction pad assembly 100 of the first embodiment, the convex portion 41 arranged on the torque receiving plate 11 for supporting the lining assembly 15 so as to be swingable is formed on the back plate portion 17 of the lining assembly 15. The lining assembly 15 can be swung freely.
また、本実施形態では、ライニング組立体15が複数であっても、それぞれのライニング組立体15に対応する位置に、一括してトルク受けプレート11に凸部41をプレス加工できる。これにより、ライニング組立体15を揺動自在に支持する構造を、簡素な構造で安価に製造できる。
Further, in the present embodiment, even if there are a plurality of lining assemblies 15, the convex portions 41 can be pressed into the torque receiving plate 11 collectively at positions corresponding to the respective lining assemblies 15. Thereby, the structure which supports the lining assembly 15 so that rocking | fluctuation is possible can be manufactured cheaply with a simple structure.
また、本第1実施形態の摩擦パッド組立て体100では、トルク受けプレート11をポンチで打ち抜き、U字形スリットを形成した後、このU字形スリットに包囲された板片がトルク受けプレート11に接続する基端で折り曲げられることにより、切り起し片37が形成される。これにより、別部材を使用せずに、打ち抜き、曲げ作業の一連のプレス加工により、回り止め規制部を簡単にトルク受けプレート11に一体形成できる。
Further, in the friction pad assembly 100 of the first embodiment, the torque receiving plate 11 is punched out with a punch to form a U-shaped slit, and then a plate piece surrounded by the U-shaped slit is connected to the torque receiving plate 11. The cut and raised piece 37 is formed by being bent at the proximal end. As a result, the anti-rotation restricting portion can be easily formed integrally with the torque receiving plate 11 by a series of stamping and bending operations without using a separate member.
更に、本第1実施形態に係る摩擦パッド組立て体100では、トルク受けプレート11は、裏面(裏板部17が対向する面と反対側の面)11aが、ブレーキパッド取付部43に密着するようにキャリパーの押圧ホルダー25に装着される。そこで、トルク受けプレート11に切り起し片37を形成した後の開口である開口47は、ブレーキパッド取付部43により塞がれる。これにより、トルク受けプレート11の外部から異物が、開口47を通り裏板部17との間に侵入するのを抑制できる。
Further, in the friction pad assembly 100 according to the first embodiment, the torque receiving plate 11 has the back surface (surface opposite to the surface facing the back plate portion 17) 11 a in close contact with the brake pad mounting portion 43. The caliper is attached to the pressing holder 25 of the caliper. Therefore, the opening 47 that is an opening after the torque receiving plate 11 is cut and raised to form the piece 37 is closed by the brake pad mounting portion 43. Thereby, it is possible to prevent foreign matter from entering the back plate portion 17 through the opening 47 from the outside of the torque receiving plate 11.

FIG. 9 is a sectional view of a
本第2実施形態に係る摩擦パッド組立て体200は、裏板部49に、ライニング組立体15を揺動可能に支持するための凸部50が配置されている。このため、図10に示すように、摩擦パッド組立て体200におけるトルク受けプレート51には、図4に示したトルク受けプレート11で設けられていた凸部41が形成されていない。
In the friction pad assembly 200 according to the second embodiment, the back plate portion 49 is provided with a convex portion 50 for supporting the lining assembly 15 in a swingable manner. Therefore, as shown in FIG. 10, the torque receiving plate 51 in the friction pad assembly 200 is not formed with the convex portion 41 provided by the torque receiving plate 11 shown in FIG.
また、本第2実施形態に係る摩擦パッド組立て体200は、裏板部49とトルク受けプレート51との間に、減衰層53が設けられている。減衰層53は、均一な厚みで形成される。減衰層53は、図10に示すように、トルク受けプレート51の内面において周壁に沿うことで、トルク受けプレート51と略相似形状で形成されている。減衰層53には、切り起し片37との干渉を避けるための複数の回避穴55が穿設されている。これにより、減衰層53の表面は、トルク受けプレート51の内面と同一の平坦面となる。減衰層53は、例えば接着層(図示略)によってトルク受けプレート51の内面に貼着される。
In the friction pad assembly 200 according to the second embodiment, a damping layer 53 is provided between the back plate portion 49 and the torque receiving plate 51. The attenuation layer 53 is formed with a uniform thickness. As shown in FIG. 10, the damping layer 53 is formed in a substantially similar shape to the torque receiving plate 51 by being along the peripheral wall on the inner surface of the torque receiving plate 51. In the attenuation layer 53, a plurality of avoidance holes 55 for avoiding interference with the cut and raised pieces 37 are formed. Thereby, the surface of the damping layer 53 becomes the same flat surface as the inner surface of the torque receiving plate 51. The attenuation layer 53 is adhered to the inner surface of the torque receiving plate 51 by, for example, an adhesive layer (not shown).
減衰層53には、例えば金属支持板と弾性材が貼りあわせて積層された状態の積層シムを用いることができ。減衰層53は、面内および面直方向に適切な弾性率を持つ積層構造となる。積層構造は、例えば弾性材であるゴム、金属支持板であるステンレス鋼板、弾性材である粘着材、金属支持板である冷間圧延鋼板、及び弾性材であるゴムを順に貼り合わせて積層させた構造とすることができる。勿論、減衰層53は、本実施形態の積層構造に限定されるものではなく、ライニング組立体15とトルク受けプレート51との間を伝搬する振動を減衰させることにより、ノイズの低減が可能となるものであれば種々の積層構造或いは単層構造を採り得る。
For the damping layer 53, for example, a laminated shim in which a metal support plate and an elastic material are laminated and laminated can be used. The damping layer 53 has a laminated structure having an appropriate elastic modulus in the in-plane and perpendicular directions. For example, the laminated structure is made by laminating, for example, rubber as an elastic material, stainless steel plate as a metal support plate, adhesive material as an elastic material, cold-rolled steel plate as a metal support plate, and rubber as an elastic material in order. It can be a structure. Of course, the damping layer 53 is not limited to the laminated structure of the present embodiment, and noise can be reduced by attenuating vibration propagating between the lining assembly 15 and the torque receiving plate 51. If it is a thing, various laminated structure or single layer structure can be taken.
更に、この減衰層53は、摩擦パッド組立て体200において、トルク受けプレート51と裏板部49との間に設けられることで、切り起し片37によりトルク受けプレート51に形成された開口である開口47を少なくとも覆う部材となる。
Further, the damping layer 53 is an opening formed in the torque receiving plate 51 by the cut and raised piece 37 by being provided between the torque receiving plate 51 and the back plate portion 49 in the friction pad assembly 200. This is a member that covers at least the opening 47.
本第2実施形態の摩擦パッド組立て体200によれば、ライニング組立体15を揺動自在に支持するため裏板部49に配置された凸部50がトルク受けプレート51に減衰層53を介して支持され、ライニング組立体15を揺動自在とすることができる。
According to the friction pad assembly 200 of the second embodiment, the convex portion 50 disposed on the back plate portion 49 for supporting the lining assembly 15 in a swingable manner is provided on the torque receiving plate 51 via the damping layer 53. Supported, the lining assembly 15 can be made swingable.
また、本第2実施形態の摩擦パッド組立て体200では、ライニング組立体15とトルク受けプレート51との間を伝搬する振動が、減衰層53により減衰する。減衰層53は、トルク受けプレート51と裏板部49との接触によるノイズの低減に寄与する。これにより、1回の制動過程時に生じる振動が減衰され、スキール騒音(所謂ブレーキ鳴き)が抑制される。
In the friction pad assembly 200 of the second embodiment, the vibration propagating between the lining assembly 15 and the torque receiving plate 51 is attenuated by the damping layer 53. The damping layer 53 contributes to noise reduction due to contact between the torque receiving plate 51 and the back plate portion 49. As a result, vibration generated during one braking process is attenuated, and squeal noise (so-called brake squeal) is suppressed.
更に、本第2実施形態の摩擦パッド組立て体200では、切り起し片37を切り起した後の開口である開口47が、トルク受けプレート51と裏板部49との間に設けられて該開口47を覆う部材としての減衰層53により覆われる。この減衰層53により、トルク受けプレート51の外部から異物が、開口47を通り裏板部49との間に侵入するのを抑制できる。
Further, in the friction pad assembly 200 of the second embodiment, an opening 47 that is an opening after the cut and raised piece 37 is cut and raised is provided between the torque receiving plate 51 and the back plate portion 49. The attenuation layer 53 as a member covering the opening 47 is covered. Due to the damping layer 53, it is possible to prevent foreign matter from entering the back plate portion 49 through the opening 47 from the outside of the torque receiving plate 51.

本第3実施形態に係る摩擦パッド組立て体300は、制動トルクを受けるガイドプレート13に少なくとも1つのライニング組立体15が揺動自在に支持されて、ライニング組立体15がディスクロータへ押圧される。ライニング組立体15は、制動時にディスクロータに押圧される摩擦材29と、摩擦材29の裏面に固着された裏板部17と、を有する。裏板部17は、ガイドプレート13に設けられたガイド孔部27に揺動自在に嵌合されるプレート嵌合部31を備える。プレート嵌合部31がガイド孔部27に挿入装着され、ディスクロータに摩擦材29が押圧された時に作用する制動トルクをプレート嵌合部31からガイドプレート13に伝達する。ガイドプレート13に固着されたトルク受けプレート57には、ライニング組立体15を揺動可能に支持する凸部41が配置されている。
In the friction pad assembly 300 according to the third embodiment, at least one lining assembly 15 is swingably supported on the guide plate 13 that receives the braking torque, and the lining assembly 15 is pressed against the disk rotor. The lining assembly 15 includes a friction material 29 that is pressed against the disk rotor during braking, and a back plate portion 17 that is fixed to the back surface of the friction material 29. The back plate portion 17 includes a plate fitting portion 31 that is swingably fitted into a guide hole portion 27 provided in the guide plate 13. The plate fitting portion 31 is inserted and mounted in the guide hole portion 27, and the braking torque acting when the friction material 29 is pressed against the disk rotor is transmitted from the plate fitting portion 31 to the guide plate 13. The torque receiving plate 57 fixed to the guide plate 13 is provided with a convex portion 41 that supports the lining assembly 15 in a swingable manner.
本第3実施形態に係る摩擦パッド組立て体300は、回り止め規制部がトルク受けプレート57の必須の構成要件とされない点で上記の摩擦パッド組立て体100,200と異なる。また、摩擦パッド組立て体300は、減衰層53が裏板部17に貼着される点も摩擦パッド組立て体200と異なる。なお、摩擦パッド組立て体300は、回り止め規制部を備えても勿論よい。その他の構成は、摩擦パッド組立て体100と略同様である。
The friction pad assembly 300 according to the third embodiment is different from the friction pad assemblies 100 and 200 described above in that the anti-rotation restricting portion is not an essential component of the torque receiving plate 57. The friction pad assembly 300 is also different from the friction pad assembly 200 in that the damping layer 53 is attached to the back plate portion 17. Of course, the friction pad assembly 300 may include a detent restricting portion. Other configurations are substantially the same as those of the friction pad assembly 100.
従って、本第3実施形態に係る摩擦パッド組立て体300では、ライニング組立体15を揺動自在に支持するためトルク受けプレート57に配置された凸部41が、減衰層53を介してライニング組立体15の裏板部17を支持し、ライニング組立体15を揺動自在とすることができる。凸部41は、トルク受けプレート57におけるそれぞれのライニング組立体15に対応する位置に、一括してプレス加工されるので、ライニング組立体15を揺動自在に支持する構造を、簡素な構造で安価に製造できる。
また、ライニング組立体15とトルク受けプレート57との間を伝搬する振動が、減衰層53により減衰する。減衰層53は、トルク受けプレート57と裏板部17との接触によるノイズの低減に寄与する。これにより、1回の制動過程時に生じる振動が減衰され、スキール騒音(所謂ブレーキ鳴き)が抑制される。 Therefore, in thefriction pad assembly 300 according to the third embodiment, the convex portion 41 disposed on the torque receiving plate 57 for swingably supporting the lining assembly 15 is provided with the lining assembly through the damping layer 53. Thus, the lining assembly 15 can be made swingable. Since the convex portions 41 are collectively pressed at positions corresponding to the respective lining assemblies 15 on the torque receiving plate 57, the structure for supporting the lining assemblies 15 so as to be swingable is simple and inexpensive. Can be manufactured.
Further, the vibration propagating between the liningassembly 15 and the torque receiving plate 57 is attenuated by the attenuation layer 53. The attenuation layer 53 contributes to noise reduction due to contact between the torque receiving plate 57 and the back plate portion 17. As a result, vibration generated during one braking process is attenuated, and squeal noise (so-called brake squeal) is suppressed.

The friction pad assembly 400 of the fourth embodiment can restrict the rotation of the lining assembly 15 by engaging the protrusion 65 of the lining assembly 15 with the locking hole 71 of the torque receiving plate 69. Therefore, it is not necessary to provide the cut and raised pieces 37 on the torque receiving plate 69. Further, the back plate portion 67 may omit the illustrated locking recess 39 with which the cut and raised piece 37 engages.
本第4実施形態に係る摩擦パッド組立て体400によれば、裏板部67に突起65が形成され、この突起65に係合する係止穴71がトルク受けプレート69に形成される。即ち、トルク受けプレート11に切り起し片37を設けた場合と同様に、別部材を用いずに、裏板部67とトルク受けプレート69のみを用いた簡素な構造で、ライニング組立体15を回り止めすることができる。また、本第4実施形態では、トルク受けプレート69への加工が係止穴71を形成するための打ち抜き作業と、凸部41を隆起させる張出加工のみとなるので、切り起し片37を形成する場合に比べ、トルク受けプレート69の加工が容易となる。
According to the friction pad assembly 400 according to the fourth embodiment, the protrusion 65 is formed on the back plate portion 67, and the locking hole 71 that engages with the protrusion 65 is formed on the torque receiving plate 69. That is, as in the case where the torque receiving plate 11 is cut and raised, the lining assembly 15 is constructed with a simple structure using only the back plate portion 67 and the torque receiving plate 69 without using separate members. Can prevent rotation. In the fourth embodiment, the processing on the torque receiving plate 69 is only a punching operation for forming the locking hole 71 and an overhanging process for raising the convex portion 41. The torque receiving plate 69 can be easily processed as compared with the case where it is formed.
