Abstract: A brake pad includes a support plate which is embodied as a cast piece as well as a friction lining that is attached therein. The support plate is provided with a planiform base and raised, positively connected parts, which are molded onto the base and are enclosed by the friction lining. At least some of the positively connected parts are surrounded in at least some areas by an adjacent cavity of the base, resulting in an improved connection of the friction lining to the support plate.

Abstract: There is disclosed a sliding member which slidably contacts an counterpart member with friction and in which a friction force is varied without changing a contact pressure. A sliding member 11 is formed by covering a steel plate with sliding materials 13a to 13e different in friction coefficient. In this case, when a sliding direction of the counterpart member 14 is set to directions of arrows A and B, a sliding material 13a of a low friction coefficient is disposed in the middle, and the sliding materials 13b to 13e are arranged so that the friction coefficient gradually increases toward both terminal sides in the directions of arrows A and B of the sliding material 13a. According to the sliding member 11, the friction force increases as the counterpart member 14 moves in the directions of arrows A and B from the middle.

Abstract: A brake lining comprises a lining body defining a plurality of holes therein and a plurality of blocks made of certain material, each block disposed in a respective hole of the lining body, whereby, a coated layer is formed on the brake disk when the brake lining is urged against a brake disk to protect the surface of the brake disk from abrasion. The holes of the lining body can be circular and the blocks can be made to match the holes. In a preferred embodiment, the disposition of the holes is to extend along a friction path between the brake lining and the brake disk. Also the disposition of the holes is to stagger the holes at the edges thereof along the friction path between the brake lining and the brake disk.

Abstract: A brake shoe for an elevator safety device comprising a supporting body provided on a vertically moving body and having a front surface thereof facing a guide rail for being pressed toward the guide rail in the event of an emergency stop; the front surface having a plurality of bottomed holes provided therein; and a plurality of ceramic braking members disposed in the holes of the supporting body and each having a top portion thereof protruding from the front surface of the supporting body and each having an outer size smaller than a complementary size of each the hole. In the brake shoe, deformation, fusion, etc. on braking surfaces and breakage of the braking surfaces due to shocks during operation can be prevented, thereby achieving an improvement in safety and reliability. Further, an elevator speed can be increased and a device size can be reduced.

Abstract: A carrier body of a brake pad for disc brakes, which carrier body is arranged to support a friction coating of the brake pad and includes a plate-shaped molded member of a hard ceramic material presenting a rear face and a circumferential edge face, and a cover secured to the member and contacting the rear face of the member. The cover is made of a material which can be shaped under pressure and/or heat and which is formed to additionally encase the circumferential edge face of the plate-shaped molded member.

Abstract: A friction pad for use in disc brakes and is formed of a sintered metal. A recess is formed in a surface of the friction pad which engages with a disc in applying the brake, and is embedded by a resin.

Abstract: A brake block for a rim brake assembly of a bicycle which has a wheel rim. The brake block comprises an elongated body member of frictional material and has a face with cavities therein. The body has a longitudinal hole extending from end to end therein. Narrow holes or porous inserts connect the longitudinal hole with the face surface and the cavities.

Abstract: Apparatus disposed in parallel relation to rails of a railway track section ahead or in advance of a railroad car retarder for applying a solid type lubricant to those areas of the car wheels frictionally contacted by the retarder and thereby suppressing excessive noise or squealing during retarding action.
