本考案は車両用、機械用デイスクブレーキの使
用に適するブレーキパツドに関する。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a brake pad suitable for use in disc brakes for vehicles and machines.
一般にデイスクブレーキ等は回転体のフランジ

In general, disc brakes etc. perform braking by applying brake pads to the flange or side of a disc of a rotating body, but these brake pads have a back plate with a copper-based sintered alloy friction material solely fixed to it. It is known that an iron-based sintered alloy friction material is solely fixed to the back plate.
銅系焼結合金摩擦材を単独で使用した場合には
摩擦係数が高いという利点がある反面、熱伝導が
良いためベーパロツクが生じること、フランジ等
の被制動部材に対して高負荷条件下では凝着する
おそれがあること、等の不具合がある。
When a copper-based sintered alloy friction material is used alone, it has the advantage of a high coefficient of friction, but on the other hand, vapor lock occurs due to its good heat conduction, and it can cause stiffness on braked parts such as flanges under high load conditions. There are problems such as the possibility of the product being damaged.
他方、鉄系焼結合金摩擦材を単独で使用した場
合には熱伝導が悪くてベーパロツクが生じず且つ
被制動部材に対しては凝着が起りずらいという利
点がある反面、摩擦係数が低く制動効果が小さい
という不具合がある。 On the other hand, when iron-based sintered alloy friction materials are used alone, they have the advantage of not causing vapor lock due to poor heat conduction and are less likely to adhere to braked components, but on the other hand, they have a low coefficient of friction. The problem is that the braking effect is small.
更に前記二つの摩擦材を混合して製作した銅一
鉄系混合体の摩擦材は全く別の悪い特性を生じ、
摩擦材としては使用できない。 Furthermore, the copper-iron mixed friction material produced by mixing the above two friction materials has completely different bad characteristics.
It cannot be used as a friction material.
そこで、本考案はベーパロツクが生じず、被制
動部材に凝着せず、摩擦係数が高く、いわゆる上
記二つの材質の優れた特性のみを持たせることが
可能なブレーキパツドを提供することである。 Therefore, the object of the present invention is to provide a brake pad that does not cause vapor lock, does not adhere to braked members, has a high coefficient of friction, and can have only the excellent characteristics of the above two materials.
上記の目的を達成するため、本考案の構成はバ
ツクプレートの表面に銅系焼結合金摩擦材と鉄系
焼結合金摩擦材を隣接して交互に１つ又は複数固

In order to achieve the above object, the structure of the present invention is characterized in that one or more copper-based sintered alloy friction materials and iron-based sintered alloy friction materials are fixed adjacently and alternately to the surface of the back plate. It is something to do.
制動作業中、銅系焼結合金摩擦材の摩耗粉が鉄
系焼結合金摩擦材の表面に付着し、同じく後者の
摩耗粉が前者の表面に付着し、銅系、鉄系の複合
効果として、それぞれの摩擦材単独では得られな
い摩擦性能が生じる。
During braking work, the wear particles of the copper-based sintered alloy friction material adhere to the surface of the iron-based sintered alloy friction material, and the wear particles of the latter also adhere to the surface of the former, resulting in a combined effect of copper and iron. , friction performance that cannot be obtained with each friction material alone is produced.
以下本考案の実施例を第１図、第２図にもとづ
いて説明する。
Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.
バツクプレート１の表面に銅系焼結合金摩擦材
２と鉄系焼結合金摩擦材３を隣接して固着するこ
とによりブレーキパツド４単体を形成している。 A brake pad 4 is formed by fixing a copper-based sintered alloy friction material 2 and an iron-based sintered alloy friction material 3 adjacent to each other on the surface of the back plate 1.
この際、被制動部材たるフランジ、円板等のロ
ータが矢印Ａ方向に回転しているとする場合、銅
系焼結合金摩擦材２は回転方向の出側、いいかえ
れば第１図に於いて、左側に配置することが好ま
しい。 At this time, when the rotor such as a flange or a disc that is a braked member is rotating in the direction of arrow A, the copper-based sintered alloy friction material 2 is placed on the exit side in the rotation direction, in other words, in FIG. , is preferably placed on the left side.
ブレーキパツド４は図示のような単独でも使用
出来るし、あるいはこの単体を複数組み合わせて
もよい。この場合銅系焼結合金摩擦材２と鉄系焼
結合金摩擦材３は必ず交互に配置されるのが好ま
しい。 The brake pad 4 can be used alone as shown, or a plurality of these pads can be used in combination. In this case, it is preferable that the copper-based sintered alloy friction material 2 and the iron-based sintered alloy friction material 3 are always arranged alternately.
更に銅系鉄系焼結合金摩擦材の摺面以外はシリ
コーン樹脂系耐熱塗料で塗布させるのが好まし
い。 Furthermore, it is preferable to coat surfaces other than the sliding surfaces of the copper-based iron-based sintered alloy friction material with a silicone resin-based heat-resistant paint.
上記のように銅系焼結合金摩擦材と鉄系焼結合
金摩擦材を組み合わせたことにより、両者の複合
化された特性が得られる。即ち、制動中におい
て、銅系焼結合金摩擦材の摩耗粉が鉄系焼結合金
摩擦材の表面に付着し、逆に後者の摩耗粉が前者

By combining the copper-based sintered alloy friction material and the iron-based sintered alloy friction material as described above, composite characteristics of both can be obtained. That is, during braking, the wear particles of the copper-based sintered alloy friction material adhere to the surface of the iron-based sintered alloy friction material, and conversely, the wear particles of the latter adhere to the surface of the former, resulting in the combined effect of the characteristics of both. is obtained.
更に詳しく述べると、摩擦係数が高く、制動効
果が大きいこと、熱伝導が悪いからベーパロツク
が生じないこと、被制動部材に対して凝着が少な
いこと、等の効果がある。 More specifically, it has the following effects: a high coefficient of friction and a large braking effect; poor heat conduction so no vapor lock occurs; and less adhesion to braked members.
尚、銅系焼結合金摩擦材を回転方向の出側に配
置した場合にはカケ防止にもなる。 Incidentally, if the copper-based sintered alloy friction material is placed on the exit side in the rotational direction, chipping can also be prevented.
