（産業上の利用分野）
本考案は、制動時にブレーキデイスクに押し付
けられるデイスクブレーキ用パツドに関し、特に
焼結合金製のデイスクブレーキ用パツドに関す
る。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pad for a disc brake that is pressed against a brake disc during braking, and particularly to a pad for a disc brake made of a sintered alloy.
（従来技術）
焼結合金製のパツドは、予め加圧成形された焼
結合金からなるブレーキライニングをパツド裏金
に重ね合せ、これらを通常500℃以上の温度で加
熱することによつてブレーキライニングを裏金に
焼結させることにより作製される。(Prior art) Pads made of sintered alloy are made by laminating a brake lining made of a sintered alloy that has been press-formed in advance on the back metal of the pad, and heating these at a temperature of usually 500°C or higher. Manufactured by sintering the metal backing.
こうして得られたパツドは、パツド裏金とブレ
ーキライニングとの熱伝導性が良好であるため、
制動時に発生するパツドとブレーキデイスクとの
摩擦熱が、パツド裏金と当接しているピストンや
ハウジングの爪部を介してブレーキ液に伝達され
ることになり、従つてブレーキ液の温度が上昇
し、最悪の場合はペーパロツクを起すという問題
があつた。 The pad thus obtained has good thermal conductivity between the pad back metal and the brake lining.
The frictional heat between the pads and the brake disc that is generated during braking is transferred to the brake fluid via the piston and housing claws that are in contact with the pad backing metal, thus increasing the temperature of the brake fluid. In the worst case, there was a problem of paper locking.
そこで裏金の裏面に断熱材を設けることにより
かかる問題に対処することが既に提案されてい
る。 Therefore, it has already been proposed to deal with this problem by providing a heat insulating material on the back surface of the back metal.
即ち、第１図に示すようにブレーキライニング
ａの裏面に焼結されたパツド裏金ｂに断熱材ｃを
添設し、パツド裏金ｂを弾性力によつて抱持する
補強板ｄにより断熱材ｃをパツド裏金ｂに圧着さ
せるというものや、或いは第２図に示すように、
パツド裏金ｂに断熱材ｃ及び補強板ｄを重ね合
せ、これらｂ，ｃ，ｄにピンｅを圧入することに
より断熱材ｃを保持させるものがある。 That is, as shown in FIG. 1, a heat insulating material c is attached to a pad back metal b sintered on the back surface of a brake lining a, and a reinforcing plate d that holds the pad back metal b with elastic force is used to insulate the pad back metal b. crimped onto the padded back metal b, or as shown in Figure 2,
There is one in which a heat insulating material c and a reinforcing plate d are superimposed on a pad back metal b, and a pin e is press-fitted into these b, c, and d to hold the insulating material c.
しかし、前者の第１図に示す提案例では、補強

信頼性に欠け、また後者にあつては、制動時に発
生する摩擦熱によつてパツド裏金ｂ、ピンｅ等が
熱膨張するが、これらは各々熱膨張率が異なるた

の欠点がある。 However, in the former proposed example shown in FIG. 1, the reinforcing plate d can be easily removed with a simple tool, etc.
In the latter case, the pad back metal b, pin e, etc. will thermally expand due to the frictional heat generated during braking, but since these have different coefficients of thermal expansion, the difference in thermal expansion will cause the pin to expand. There are drawbacks such as the possibility that e may come loose.

にするため２箇所以上であることが好ましい。(Example) The present invention will be described below with reference to an example shown in the drawings. As shown in FIGS. 3 and 4, a pad back metal 1 has a plurality of rivet holes 2 formed therein. These rivet holes 2 consist of a large diameter part 2a and a small diameter part 2b, and the rivet 3 has a head part 3.
They are inserted so that a is located in the large diameter portion 2a, and the shaft portion 3b is located in the small diameter portion 2b, with the tip of the shaft portion 3b protruding from the rivet hole 2. The number of rivet holes 2 is preferably two or more in order to ensure the attachment of the heat insulating material 5, reinforcing plate 6, etc. to the brake lining 4, as will be described later.
上記のようにしてリベツト３が挿入された裏金

のことである。 The back metal 1 into which the rivets 3 have been inserted as described above is superimposed on the brake lining 4.
During this overlapping, the head 3a of the rivet 3
The top surface 3c of the brake lining 4 is brought into contact with the back surface of the brake lining 4. Brake lining 4 here
The back surface of the brake lining 4 is the surface opposite to the surface of the brake lining 4 that is pressed against a brake disc (not shown).
ところでブレーキライニング４であるが、これ
は焼結合金からなり、予め所定の形状に加圧成形

ニング４との接着に対する信頼性が向上する。 After the pad back metal 1 is superimposed on the brake lining 4 as described above, they are heated to 500° C. or higher to sinter the pad back metal 1 to the brake lining 4. At this time, rivet 3 and back money 1
Therefore, water will not enter through these gaps, and rust will be prevented, improving the reliability of the bond between the pad back metal 1 and the brake lining 4. do.
こうして焼結が終了したならば、第５図及び第

ｂにワツシヤ７を取付けた後、軸部３ｂの先端部
をリベツト打ちしてかしめる。 When the sintering is completed in this way, as shown in FIGS. 5 and 6, the shaft portion 3b of the rivet 3 is inserted into the heat insulating material 5 in which the mounting hole 5a is formed, and the heat insulating material 5 is attached.
is attached to the pad back metal 1, and the reinforcing plate 6 is attached to the heat insulating material 5 by inserting the shaft portion 3b into the attachment hole 6a of the reinforcing plate 6. And finally the shaft part 3
After attaching the washer 7 to b, the tip of the shaft portion 3b is riveted and caulked.
尚、上記補強板６は、断熱材５の材質が、その

かしめ部８の外径が大きく設定できれば、必要と
しない。 Note that the reinforcing plate 6 is not particularly required if the material of the heat insulating material 5 has sufficient strength and durability. Further, the washer 7 is used to prevent warping of the heat insulating material 5 and the reinforcing plate 6 when the rivet 3 is caulked, but it is not necessary if the outer diameter of the caulked portion 8 of the rivet 3 can be set large.
ところで上記構成にかかるパツドの補強板６側
には図示しないピストンが装着されまたハウジン
グの取付用爪が取付けられるため、リベツト３の
位置としては、これらと干渉しない個所を選ぶ必
要がある。 Incidentally, since a piston (not shown) and housing mounting claws are attached to the reinforcing plate 6 side of the pad according to the above structure, it is necessary to select a location for the rivet 3 so that it does not interfere with these.
尚、パツド裏金１としては、ステンレススチー

ましい。 In addition, the padded back metal 1 is stainless steel plated with copper, and the rivet 3 is
The brake lining 4 is preferably made of copper or plated with copper, the brake lining 4 is preferably a sintered alloy of copper strips, and the heat insulating material 5 is preferably made of a material with low thermal conductivity, such as ceramic, asbestos, or a heat-resistant resin such as glass fiber.
（効果）
本考案は、以上から明らかなように、断熱材５
が取り付けられる前にリベツト３はパツド裏金１
に焼結されて位置決めされているので、かしめ時
にリベツト３の位置がずれることがなく、したが
つてリベツト３の位置精度が高い。(Effect) As is clear from the above, the present invention has
Rivet 3 is attached to padded back metal 1 before it is installed.
Since the rivet 3 is sintered and positioned, the position of the rivet 3 will not shift during caulking, and therefore the positional accuracy of the rivet 3 is high.
また制動時に発生する摩擦熱によつて各部材
１，３，４，５が膨張しても前記のごとくリベツ
ト３はパツド裏金１に焼結により強く固着されて
いるので、リベツト３が摩擦熱によつてゆるむこ
とはない。 Furthermore, even if each member 1, 3, 4, 5 expands due to the frictional heat generated during braking, since the rivet 3 is strongly fixed to the pad back metal 1 by sintering as described above, the rivet 3 will not be affected by the frictional heat. It doesn't twist or loosen.
さらに断熱材５の固定に際してはピン等を必要
とせず、リベツト３をかしめるだけで断熱材５は
固定され、したがつて部品点数の低減が図れる。
また、ブレーキライニングにリベツト用の貫通孔

ツトのかしめ時において力がブレーキライニング
の全表面に均等に分散されるので、かしめ時の安
定性がよい。 Further, when fixing the heat insulating material 5, no pins or the like are required, and the heat insulating material 5 is fixed simply by caulking the rivets 3, thus reducing the number of parts.
Furthermore, since there is no need to provide through holes for rivets in the brake lining, its surface area does not decrease, and therefore the service life remains the same as before. Moreover, since the force is evenly distributed over the entire surface of the brake lining when the rivet is caulked, stability during caulking is good.
