摘要： PROBLEM TO BE SOLVED: To easily judge that a lining reaches its allowable wear limit from the outside of a disk brake device by fitting a lining wear detecting device. SOLUTION: In a lining wear detecting device, detection pins 24 of the same material as that of a lining material are implanted on each end part in the longitudinal direction of a lining fitting plate 16, and a through hole 26 is provided in the detection pin 24. The lining fitting plate 16 is provided with a spring fixing rivet 22 to turnably hold a V-shaped spring 18 and an inflection point part of the spring 18, and a display board 20 is provided on an outer end part of the spring 18. The end part of the spring 18 is pulled toward the detection pin 24, and a wire 28 is passed through the through hole 26 and fixed thereto. When the wear of the lining 11 reaches its limit, a wire 28 is detached from the through hole 26 in the detection pin 24, and the end part of the spring 18 is exposed outside of the outer edge of the lining fitting plate 16 by the releasing force. The display board 20 provided on the end part of the spring 18 is also exposed out of the outer edge of the lining fitting plate 16, enabling to know the replacement timing due to the wear of the lining 11.

摘要： PURPOSE:To reduce the weight of a shoe and improve its durability by a method wherein the shoe comprising a back plate made of nonmagnetic metal and a sliding friction lining made of molybdenum, molybdenum alloy or tungsten is fixed on a shoe receptor while cut grooves are formed in a direction intersecting the running direction of the shoe. CONSTITUTION:On a shoe receptor to be mounted on a carriage, a shoe 5 comprising a back plate 6 made of nonmagnetic metal and a sliding friction lining 7 metal-joined with the back plate 6 made of molybdenum, molybdenum alloy or tungsten wherein thermal expansion coefficient is small, specific gravity is large, specific intensity is small with high melting point and high anti-friction property is fixed. Then cut grooves 8a,8b reaching from the sliding friction lining 7 of the shoes 5 to the back plate 6 at least in a direction intersecting the running direction of the shoe 5. Therefore the weight of the shoe 5 can be reduced as well as by dividing the sliding friction lining 7 by the cut grooves 8a,8b cracks due to difference in thermal expansion coefficient between the lining and the back plate 6 may not easily occur thereby remarkably improving durability of the shoe 5.

摘要： PROBLEM TO BE SOLVED: To provide a brake shoe for a magnetically levitating vehicle suited for lightening of weight, and excellent in wearing resistance as well as in toughness, maintaining good brake performance over a long period. SOLUTION: In a non-magnetic metal-made back plate 3 tightened to a brake shoe mounting part of a vehicle, a plate-shaped friction material 6 is layered to present a slide friction surface 4. The material 6 is formed in plate shape by a carbon fiber reinforced carbon composite, layered in a surface of a heat absorbing plate 11, and is provided with a slide friction plate 12 presenting the slide friction surface 4 and a ceramic composite material-made friction suppressing block 20 dispersedly arranged in the slide friction plate 12, so that a tip end surface carries partly the slide friction surface 4.

摘要： PURPOSE:To improve the life of a brake for a vehicle by using the brake for the vehicle when the electric braking power by a main electric motor is attenuated in the low speed traveling range where the regular brake is used, and using the multi-plate type braking device in supplementing the braking power of the regular brake in the emergency braking case, or by using it in an emergency when the braking power by the main electric motor becomes invalid. CONSTITUTION:A brake 16 for wheels where metallic friction plates 15a, 15b are used on the sliding surface with the wheels 3 is used as a supplement to a regular brake when the electric braking power by a main electric motor 5 is attenuated in the low speed traveling range where the regular brake is used. On the other hand, a multi-plate type braking device 10 which is connected to a main electric motor shaft 6 through a coupling 9 and consists of a plurality of rotors and stators, and a C/D composite friction material is used when the braking power of the regular brake is supplemented when being used as the emergency brake, when the electric braking power by the main electric motor 5 becomes invalid, and when the emergency brake is applied in the traveling range at full speed.

摘要： PURPOSE:To enhance reliability and durability by specifying respective material to be used for end support members which are fixedly provided for the both ends of each back plate in the longer direction, and main friction members interposed at the intermediate section of each back plate in the longer direction, and thereby interposing a heat insulating shock absorbing member between each main friction member and each back plate. CONSTITUTION:At the braking time of emergency landing for a magnetic levitation type vehicle, braking force is produced by sliding friction between each one of end support members 2 and main friction members 1 and the surface of a concrete track 14. And a shoe backing member 11 is subjected to moment due to friction force around a mounting pin 15 for a longitudinal support member 12 and a vertical support member 13, so that the end support member 2 at the front side position in the running direction and the main friction members 1 are subjected to theoretically great bearing pressure P. In this case, each end support member 2 is made of Mo, Mo alloys or stainless steel, it is thereby hardly damaged by cracking and the like, and the end support members and the action of heat insulating shock absorbing members 3b therefore combine to effectively prevent the main friction members 1 from being damaged. And the main friction members 1 made of C/C composites hardly reduce their own strength and frictional coefficient even at high temperature, thereby making it possible to effectively apply the brake for the vehicle.
