などの新たな不具合が生じてくる。(Prior art) Conventional resin-molded clutch facings are made by impregnating asbestos non-woven fabric with binder such as phenol resin and heat-molding it, whereas conventional resin-molded clutch facings are made by impregnating long fiber asbestos string with phenol resin and heat-molding it. Compared to Clutch 7 Acing, it is generally of stable quality and has excellent friction performance, such as a much flatter temperature characteristic of the friction coefficient. However, resin molded clutch facings are superior to woven clutch facings in terms of the degree of difficulty in causing the phenomenon in which the facings are unable to resist the rotational force of the clutch disc and deform and sometimes separate or break from the disc, that is, in terms of rotational burst strength.
Because of its inferiority, conventionally it had to be used only in specific car models where rotational burst strength was not an issue. Therefore, in order to improve the rotational burst characteristics,
A method of reinforcing the strength of clutch facings has been proposed, such as by installing a metal mesh (e.g., copper) in the facing using a woven asbestos fabric, which has much greater strength than non-woven fabric. has been done. However, although these methods improve the rotational burst characteristics, the specific gravity of the clutch facing of the product increases significantly, which increases the inertia torque of the clutch disc and makes it impossible to smoothly shift the gear. A new problem will arise.

This is blended into the 7-thin side part (clutch disc side part). To further explain the invention in detail,
The backing material used in the present invention is made by spraying chopped glass fiber strands and dispersing them on a flat surface by scattering, preferably uniformly dispersing them in a non-oriented manner, and then adding polyester or the like as a bonding agent between the strands. It is made by impregnating chopped i-land mat with liquid phenol resin, which is a binder for resin mold clutch facing material. In this case, the chopped strand mat preferably has high strength and rigidity, and from this point of view, the chopped strands preferably have long and thick fibers, for example, a strand length of about 50 mm and a strand diameter of about 13 μm. Good to use. The content of polyester may be any amount suitable to enhance the bonding between the strands. The amount of phenol resin to be impregnated may be such that the backing material has high rigidity and strength when the resin is cured after molding. For example, it is preferable to impregnate the chopped strand mat in an amount of about 10% by weight.

ェーシング1を製造する。As shown in FIG. 1, K, the clutch facing 1 of the embodiment
is a chopped strand mat of glass fiber impregnated with phenol resin (strand length SO =..., strand diameter 13 μm1) with a disc ring-shaped facing.
A backing material 2 made of a polyester binder (polyester binder) and a resin molded clutch facing material 3 containing cashew dust and barium sulfate with a base of asbestos and a phenol resin binder are laminated and integrally molded by heating and pressing. Then, the facing 1 is used, and the backing material 2 is attached to both sides of the clutch disk of a disc clutch (not shown) with the backing material 2 facing toward the disk side. To explain in detail the manufacturing process of this clutch facing 1, as shown in FIG. They are sequentially immersed in the liquid phenol resin 6 filled in the tank 5, and the resin 6 is impregnated with an appropriate amount of chopped strand pine) 41C. Next, the chopped strand mat after impregnation is heated to pre-cure the 7-enol resin at a temperature of, for example, 120°C for 5 minutes, and then cut with a cutter or the like to form a disc ring as shown in Fig. 3. A shaped backing material 2 is formed. On the other hand, asbestos is impregnated with a predetermined amount of 7-enol resin, then cashew dust and barium sulfate are mixed therein, and then preforming is performed to produce a resin molded clutch facing material 3 (FIG. 1) in the shape of a disc ring. Thereafter, as shown in FIG. 4, the backing material 2 and then the resin-molded clutch facing material 3 are placed in a thermoforming mold 7 for forming this type of clutch facing, and the temperature is 160° C. and the pressure is 100 kg/cm. The molded product is subjected to pressure and heat molding under CD conditions, and then the molded product is heat treated at a temperature of 200° C. for 4 hours to harden and ripen. Further, the facing material 3 is polished to produce a facing of a predetermined thickness, and finally the integrally molded clutch facing 1 shown in FIG. 1 is manufactured.

フェーシングと比較して格段に小さかった。When we investigated the one-turn burst characteristics of the clutch facing 10 manufactured according to the above-mentioned process, it was confirmed that the rotational burst strength of the facing 1 was significantly improved compared to that of a conventional resin-molded clutch facing. It was done. Further, when a specific gravity measurement test was conducted, the specific gravity of the clutch facing 1 was significantly lower than that of a resin molded clutch facing made of metal mesh or asbestos woven fabric.

に広範に適用可能である。(Effects of the Invention) As described above, the clutch facing of the present invention has a chopped strand mat of glass fiber on the back side of the facing, which has high strength and high rigidity and has a lower specific gravity than conventional reinforcing materials. By applying this, the strength and rigidity of the facing are greatly increased, and even if the clutch engagement conditions are severe, the facing is less likely to be deformed or distorted, and extremely unlikely to peel or break, resulting in increased rotational burst strength. In addition, since the specific gravity of the facing does not increase significantly, there are no problems such as smooth shifting of the transmission gear. Therefore, the clutch facing of the present invention is widely applicable to various vehicle types.
