【発明の詳細な説明】
本発明は湿式焼結摩擦材料に係り、臀に従来より摩擦特
性の改良された材料に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wet sintered friction material, and more particularly to a material with improved friction properties for the buttocks.

改＾がｌ！望されていた。Bronze-based sintered materials have been widely used as wet friction materials used in wet friction clutches, brakes, etc., but their friction properties are not necessarily sufficient.
Kai ^ is l! It was desired.
本発明はこの要望を満たすためになされたもので、重量

する４のである。The present invention was made to meet this demand, and the weight ratio is 60 to 11% copper to SOn and 1 to 111% tin! , zinc 1~
10-1 graphite 5~201g, calcined alumina 8~15g!
4. One of the contents is a wet sintered friction material characterized by the following.

ルミナを用い、その量は通常７−以下であった。焼成ア
ルミナを８〜１５％含有させることにより、湿式摩擦材
料として用いた場合に次のような９Ｍが生ずることを、
本発明の発明者は発見したのである。The material of the present invention is characterized in that it contains calcined alumina 8 to 15s2 negative. In conventional bronze-based sintered friction materials, silica or fused alumina is used as such hard particles, and the amount thereof is usually 7 or less. By containing 8 to 15% of calcined alumina, the following 9M is produced when used as a wet friction material.
The inventor of the present invention has discovered this.
第１の％値は、ｌ＃擦係数が高いことである。従来の青
銅系焼結摩擦材料にくらべて、約２０％−い。The first % value is a high l# friction coefficient. Approximately 20% lower than conventional bronze-based sintered friction materials.
ａｇ２０％黴は、動ｊｌｌ係員数と靜岸−係数との差が
小さいこと、すなわち靜ｊＨ１係数に対するａ摩擦係数
の比が大きいことである。従来の青銅系焼結摩擦材料に
おいてこの比が約０，７であるのに対して、本発明材料
では約０．８である。このことは、指速の影譬による摩
擦係数の変化か小さくなるという意味て、好ましい。The ag20% difference is that the difference between the number of dynamic Jll personnel and the coefficient of friction is small, that is, the ratio of the a friction coefficient to the coefficient of JH1 is large. While this ratio is approximately 0.7 in conventional bronze-based sintered friction materials, it is approximately 0.8 in the material of the present invention. This is preferable in the sense that the change in the coefficient of friction due to finger speed is reduced.
第３の特徴は、油の種類による摩擦係数の変動が小さい
ことである。The third feature is that the coefficient of friction varies little depending on the type of oil.
本発明材料は、青銅系焼結ｍ鰺材料の改良でめ３輿
るから、従来の同材料と同様の方法で製造することがで
き、止むｔ傅ぬ不純物その他従来の同材料製造技術につ
いて周知の変更を加え得ることは、もちろんである。Since the material of the present invention is an improvement on the bronze-based sintered mackerel material, it can be manufactured using the same method as the conventional material, and does not contain any undue impurities and other conventional manufacturing techniques for the same material. Of course, changes may be made.
