本考案はクラツチの摩擦係合板、特に油中で使
用するのに適した湿式摩擦係合板に関するもので
ある。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a friction engagement plate for a clutch, particularly a wet friction engagement plate suitable for use in oil.
［従来の技術］
湿式摩擦係合板は、通常、リング状の基板（芯

いられている。[Prior Art] Wet friction engagement plates usually have a ring-shaped substrate (core metal) and a friction material attached to both sides of the substrate.The friction material is made of wood pulp or the like. Paper base materials that are wet-formed from organic fibers and frictional property modifiers are impregnated with thermosetting resins such as phenolic resins, and then compression molded.
摩擦材を構成する紙質基材は、繊維の絡みが良
いので摩擦材の層間剥離が起り難く、、またコス
トが比較的に安いため一般に使用されている湿式
摩擦係合板は基本的には上記の構造とされてい
る。 The paper base material that makes up the friction material has good intertwining of fibers, making it difficult for the friction material to delaminate, and the cost is relatively low, so the commonly used wet friction engagement boards are basically the above-mentioned. It is said to be a structure.
しかし、この摩擦材は木材パルプを主体として
いるため、耐熱性に劣るという欠点を有し、摩擦
係合時に発生する熱によつて部分的な焼けが生

材の摩耗がさらに促進され、かつ摩擦係数が低下
し、ひいては耐久性が悪くなるという問題があつ
た。 However, since this friction material is mainly made of wood pulp, it has the disadvantage of poor heat resistance, and the heat generated during frictional engagement causes local burns, resulting in unevenness on the surface of the friction material. This causes problems in that wear of the friction material is further accelerated, the coefficient of friction is reduced, and durability is deteriorated.
このような問題点を解消するために、耐熱性を
向上させる目的で、木材パルプなど紙質基材に石
綿繊維を配合し、摩擦熱による部分的な焼けや、
それに起因する各種の不都合を解消する摩擦材が
提供されている。 In order to solve these problems, asbestos fibers are blended into paper base materials such as wood pulp to improve heat resistance, which prevents local burns caused by frictional heat.
Friction materials have been provided that eliminate the various inconveniences caused by this.
さらに、耐熱性を向上させるための別な方法と
して、例えば特開昭56−90135号公報には摩擦材
に複数の溝を設け、摩擦面への油の供給を促進し

する摩擦円板の製造方法が形成されている。 Furthermore, as another method for improving heat resistance, for example, Japanese Patent Application Laid-Open No. 56-90135 discloses that a plurality of grooves are provided in the friction material to promote oil supply to the friction surface and cool the friction material. By doing so, a method for manufacturing a friction disk that prevents thermal deterioration is formed.
また実開昭61−131543号公報には、回転中心か

いた気孔率の大きい層を有する湿式摩擦材が記載
されている。 Furthermore, Japanese Utility Model Application Publication No. 131543/1983 describes a wet friction material having a convex arc shape facing outward from the center of rotation and a layer with high porosity facing toward the rear of the rotation.

摩擦材に浸み込んだ油および溝内の油が遠心力に
より摩擦係合板の外周側へ飛散しやすい。[Problems to be Solved by the Invention] However, the above-mentioned conventional wet friction engagement plate has a problem in that the asbestos fibers have an adverse effect on the human body due to the inclusion of asbestos. In addition, the grooves formed on the surface of the friction material and the convex arc-shaped layer with high porosity are continuous from the inner periphery to the outer periphery of the friction material, making it easy for oil to flow out from the friction material, especially in recent years. There is a tendency for high rotation and high output,
Oil that has soaked into the friction material and oil in the grooves tends to scatter toward the outer periphery of the friction engagement plate due to centrifugal force.
そのために油量が不足して充分な冷却が行なわ
れなくなり、摩擦熱による劣化が進行して耐久性
が悪くなるという問題点がある。 Therefore, there is a problem in that the amount of oil is insufficient and sufficient cooling is not performed, and deterioration due to frictional heat progresses and durability deteriorates.
本考案は摩擦材から遠心力による油の流出を調
整し、耐熱性を向上させた湿式摩擦係合板を提供
するものである。 The present invention provides a wet friction engagement plate that adjusts the outflow of oil from the friction material due to centrifugal force and has improved heat resistance.

徴とするものである。[Means for Solving the Problem] In order to solve the above-mentioned problems, the present invention provides a wet friction engagement plate in which an annular friction material is fixed to the surface of a substrate, in which the outer peripheral edge of the friction material is crushed;
It is characterized in that the thickness of the outer circumference is thinner than the thickness of the inner circumference.

る。[Function] The wet friction engagement plate of the present invention is partially immersed in oil and used while being exposed to oil droplets, thereby supplying oil to the friction material. When this wet friction engagement plate is rotated at high speed and centrifugal force is applied, the oil that has soaked into the friction material tends to be pushed out toward the outer periphery of the friction material due to the centrifugal force. By crushing the area, the micropores at the outer periphery are crushed and the porosity is reduced. Therefore, it is possible to adjust the scattering of oil from the outer periphery, ensure the amount of oil retained, prevent a decline in cooling performance due to lack of oil, and obtain a wet friction engagement plate with improved heat resistance.

止する。 Here, the friction engagement plate 10 is made of organic fibers such as linter pulp, wood pulp, and pulp-like aromatic polyamide, inorganic fillers such as barium sulfate, kaolin, clay, calcium carbonate, alumina, and asbestos, as well as cashew dust and rubber. A paper base material made by wet paper-making of an organic filler such as powder is punched into a predetermined shape, and a phenol resin,
It is impregnated with a thermosetting resin such as melamine resin, melamine-modified phenolic resin, or cashew nut oil-modified phenolic resin, and after a drying process, it is bonded to the substrate 14, and is then molded using a press molding machine with a stepped mold as shown in FIG. Obtained by heating and pressure molding. Furthermore, in order to further reduce the porosity of the outer peripheral edge of the friction material, the crushed outer peripheral edge is immersed again in the above-mentioned thermosetting resin solution and dried and hardened. This further reduces oil scattering. The friction engagement plate 10 described above is attached to a rotating body such as a rotating shaft and is used in a wet state with oil, but even when the friction engagement plate 10 rotates at high speed and centrifugal force is applied, the friction material 15 The oil that has penetrated into the interior has a crushed portion 12 on the outer periphery, and this portion has a small porosity, so it does not scatter from the outer periphery, thereby preventing a drop in cooling performance due to lack of oil. .
