摘要： PROBLEM TO BE SOLVED: To balance heat resistance, such as fade resistance, with anti-squeal performance in a friction material. SOLUTION: This friction material 10 includes a resin binding material 1 and carbonization granulated substances 2 dispersed and maintained in the resin binding material 1. The carbonization granulated substances 2 are carbonized products obtained by carbonizing a granulated substance containing a fibrous substrate, the resin binding material, and at least one filler. Since the carbonization granulated substances 2 contains no organic matters such as resin binding materials, the contents of organic matters such as resin binding materials are greatly reduced in the friction material to greatly improve the heat resistance such as fade resistance in comparison with the conventional friction material in which the granulated substance containing the resin binding material is dispersed and maintained. Since the resin binding material 1 is filled between the carbonization granulated substances 2, a spring constant in the friction material is lowered to improve the anti-squeal performance in comparison with the conventional friction material using a carbonized organic material as a binding material.

摘要翻译：要解决的问题：在摩擦材料中平衡耐褪色性，抗摩擦性能等耐热性。解决方案：该摩擦材料10包括分散并保持在树脂粘合材料1中的树脂粘合材料1和碳化粒化物质2.碳化粒化物质2是通过碳化含有纤维基材的颗粒状物质获得的碳化产物，树脂粘结材料和至少一种填料。由于碳化粒化物质2不含有树脂粘结材料等有机物质，摩擦材料中的树脂粘结材料等有机物质的含量大大降低，与以往的摩擦材料相比，能够大幅提高耐褪色性等耐热性其中分散并保持含有树脂粘合材料的颗粒状物质。由于树脂粘合材料1填充在碳化粒状物质2之间，与使用碳化有机材料作为粘合材料的常规摩擦材料相比，摩擦材料中的弹簧常数降低，以提高防啸声性能。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a friction material which is excellent in stability of braking performance and hardly causes abnormal sound even when water is present on the surface by incorporating potassium titanate fibers thermally treated at 300 deg.C or higher as at least a part of a fiber component into a friction mate rial comprising a filler component and a binder component contg. the fiber component. SOLUTION: The thermal treatment is performed at 300 deg.C or higher, pref. 300-400 deg.C, for 1-8hr and may be carried out after molding the friction material. The treatment is considered to separate hydrophilic OH groups from potassium titanate to render the molecular terminals hydrophobic. Potassium hexatitante fibers or potassium octatitanate fibers are used as the potassium titanate fibers. The binder component comprises the fiber component and a thermosetting resin (e.g. a phenol resin, a urea resin, a melamine resin, or a modification of these resins). Graphite, barium sulfate, calcium carbonate, etc., are used as the filler component.

摘要： PURPOSE:To reduce generation of squeak by a brake pad vibrating as a rigid body. CONSTITUTION:A contacting member drive cylinder 82 is provided opposite to the end part of a leading side of a back plate 20 of a vehicle moving forward and a piston rod 104 is made to come in contact with the back plate 20 by transmitting master cylinder pressure to the fluid pressure chamber 108, while supply of brake fluid to the fluid pressure chamber 108 is cut off by providing a cutoff valve 112, and the fluid pressure in the fluid pressure chamber 108 is maintained to the height of the piston rod 104 contacting the back plate 20 with a force of 49N (5kgf). The piston rod 104 is in a non-braking position when brake is not applied but moves forward and contacts the back plate 20 when braking, restrains vibration and reduces noise by regulating the movement of the end part of the leading side of the back plate 20. The contacting member may be contacted with the back plate by a device using an electric motor as its drive power source, or the vibration may be restrained by friction by making the contacting member coming in contact with the side surface at a right angle to the friction surface of the back plate.

摘要： PURPOSE:To suppress the temperature of a brake surface to a low value and to generate the proper brake power of a drum brake by forming an heat insulating layer on the inner peripheral surface of a drum part. CONSTITUTION:A drum-in-disc rotor 10 comprises an annular disc part 11 having a given width; and a cylindrical drum part 12 with a given diameter arranged on the inner periphery thereof. A lining shoe 24 for a drum brake is disposed on the inner peripheral side of the drum part 12. A parking brake consists of a drum brake, through operation of the parking brake, a lining shoe 24 is spread, a shoe lining 24a is brought into pressure contact with the inner peripheral surface of the drum part 12 and brake torque is exerted on the drum part 12. Further, a heat insulating layer 14 is formed on the inner peripheral surface of the drum part 12. The heat insulating layer 14 is a flame-spray layer and has low thermal conductivity and the more the heat insulating layer is thick, the more a temperature increase suppression effect is improved. In composition of the heat insulating layer 14, the friction factor of a brake surface is increased by using a rigid particle-form component and brake torque of the drum brake is increased.

摘要： PURPOSE:To reduce the occurrence of vibration due to the generation of a heat spot by providing a thermal conductive layer having a coefficient of thermal conductivity larger than that of a heat insulating layer on each heat insulating layer disposed on both sides of a disc metallic main body and making the surface of each thermal conductive layer as a friction surface. CONSTITUTION:A main body 12 of a disc rotor 10 is cast by gray cast iron, and a heat-insulating layer 22 composed of chromium oxide is formed on both side faces of flange portion 16. A thermal conductive layer 24 composed of chrome, carbon and copper is formed on the heat insulating layer 22 by plasma flame spraying and finished by grinding. Accordingly, the frictional heat generated on friction surfaces 26, 28 is intercepted by the heat insulating layer 22, so that as the frictional heat is hardly transmitted to the main body, a temperature rise of the main body 12 is small so as to decrease partial temperature difference depending on the existence/absence of a vent hole 20 and to reduce the occurrence of a heat spot.

摘要： PURPOSE:To prevent deterioration in frictional resistance at a sliding surface, by thermally spraying a wear-resistant and heat-resisting metallic material on the sliding surface of a disk rotor body and by applying reduction treatment to the above body so as to reduce the amount of oxide in the thermally sprayed layer to a specific value or below. CONSTITUTION:A wear-resistant and heat-resisting metallic material is thermally sprayed on the sliding material 2, with which a brake friction pad is to be brought into contact, of a disk rotor body 1 composed of Al alloy, cast iron, etc., so as to form a thermally sprayed layer 3. Further, a coppery or ferrous material is mainly used as the above thermal spraying material, and thermal spraying is carried out by means of a wire gas thermal spraying method, a wire arc thermal spraying method, etc. Subsequently, the above-mentioned disk rotor body is subjected to reduction treatment in a hydrogen air flow in a reducing furnace. By this reduction treatment, the amount of oxide contained generally by >=about 10% in the above thermally sprayed layer 3 is reduced to

摘要： PURPOSE:To improve the strength of the peripheral wall part of a rivet hole by making the composition ratio of a binder to a base material of the peripheral wall part of said rivet hole larger. CONSTITUTION:30% base material made of asbestos, 30% binder made of phenolic resin, 20% calcium carbonate as a friction adjusting agent, and 20% metal powder are well mixed and thermoformed for 3min using a metal mold consisting of an upper mold 2 having a projected part 21 and a lower mold 3 having a recessed part 31. Thereby, the composition ratio of a binder to a base material of the peripheral wall of a rivet hole becomes larger than the composition ratio of the binder to base material of the inside of a clutch facing base body, improving the strength of the peripheral wall part of the rivet hole.
