In addition, there are some types in which two or more types of friction materials are formed into segments and fixed to a core plate.
本発明は、上記の摩擦板の中でも、２種以上の摩擦材を
組合せたものに関する。摩擦材を２種以上にする理由は
、各々の摩擦材の特性を兼ね備えた摩擦板を得るためで
ある。このような摩擦板は、通常、第５図に示されるよ
うに、摩擦材Ａ及び摩擦材Ｂとの組合わせからなる。摩

従って動摩擦係数が漸減する性質を備えている。摩擦材
Ｂは、比較的動摩擦係数が高く、摩擦板の相手側となる
メイティングプレートとの相対回転が大きくなるに従っ
て動摩擦係数が漸増する性質を備えている。Among the above-mentioned friction plates, the present invention relates to a friction plate in which two or more types of friction materials are combined. The reason for using two or more types of friction materials is to obtain a friction plate that combines the characteristics of each friction material. Such a friction plate usually consists of a combination of friction material A and friction material B, as shown in FIG. The friction material A has a relatively high coefficient of static friction, and has a property that the coefficient of dynamic friction gradually decreases as the relative rotation with the mating plate, which is the other side of the friction plate, increases. The friction material B has a relatively high coefficient of dynamic friction, and has a property that the coefficient of dynamic friction gradually increases as the relative rotation with the mating plate, which is the other side of the friction plate, increases.
摩擦材Ａは、静摩擦係数が大きいため相対回転がＯのと

係数が小さいため、摩擦板とメイテイングプレートとの
保合時にシャダーやショックを生じないという観点から
好適であるが、保合後にトルク容量が不足して滑りが生
じるという欠点がある。Friction material A is suitable from the viewpoint that no slipping occurs when the relative rotation is O due to its large static friction coefficient, but it has the disadvantage that shudder and shock occur just before the friction plate and the mating plate are engaged. . Friction material B has a small coefficient of static friction, so it is suitable from the viewpoint of not causing shudder or shock when the friction plate and mating plate are engaged, but it has the disadvantage that the torque capacity is insufficient and slipping occurs after engagement. There is.
そこで、異種の摩擦材をコアプレートに固着することが
考えられる。しかし、単に、摩擦材をコアプレートに固
着しただけでは、複数の摩擦材の特性を兼ね備えた摩擦
板を得ることはできない。Therefore, it may be possible to fix different types of friction materials to the core plate. However, it is not possible to obtain a friction plate that has the characteristics of a plurality of friction materials by simply fixing the friction material to the core plate.
本発明の目的は、異種摩擦材の夫々の特徴を充分に機能

やショックを生じることがない。Function: In the friction plate of the present invention, since the second friction material protrudes from the surface of the first friction material, at the time when engagement with the mating plate begins, the second friction material first slides. start the movement. Since the second friction material has a relatively high coefficient of dynamic friction,
The friction plate and the mating plate, which are rotating relative to each other, quickly synchronize. Furthermore, since the static friction coefficient of the second friction material is relatively low compared to that of the first friction material, no shudder or shock occurs at the time when relative rotation ceases, that is, immediately before engagement.

性体が圧縮されると、メイティングプレートは、第２の
摩擦材だけでなく第１の摩擦材とも係合する。これによ

第１の摩擦材によって確保される。When the relative rotation between the friction plate and the mating plate is eliminated and the elastic body is compressed, the mating plate engages not only the second friction material but also the first friction material. As a result, the transmission torque capacity in the absence of relative rotation is mainly ensured by the first friction material.

できる。In addition, in order to engage the first friction material and the mating plate, it is sufficient to generate two stages of hydraulic pressure. In other words, the first stage hydraulic pressure is applied to a level that does not compress the elastic body or a level that compresses the elastic body. The hydraulic pressure of the second stage is set to such an extent that the mating plate does not engage with the first friction material even if This is achieved by setting the body to a degree of compression. Such settings can be easily implemented by providing an orifice or solenoid valve in the hydraulic circuit.
