Abstract: A brake lining includes a mounting plate, sliding members and elastic members. The sliding members are arranged in the transverse direction and the longitudinal direction of the mounting plate on one surface of the mounting plate to form transverse rows and longitudinal rows. The elastic members are provided in correspondence with the sliding members. Each of the elastic members is disposed between the corresponding sliding member and the mounting plate. A gap exists between adjacent transverse rows, and extends over the entire length of the transverse rows. A gap exists between adjacent longitudinal rows, and extends over the entire length of the longitudinal rows. The gap has a width that is smaller than a width of the gap.

Abstract: A brake lining is provided that is to be pressed against a sliding surface of a brake disk fastened to a wheel or an axle of a railway vehicle. The brake lining includes: a plurality of friction members arranged to be spaced from each other, each of the friction members having a front surface that is to face the sliding surface; a back board fastened to a back surface of each of the friction members; and a base plate supporting each friction member at a region including a center portion of the respective friction members. Two friction members are taken as a pair, and the back board that is fastened to the pair of friction members is a one-piece member, and a width of the back board at a space between the friction members of the pair of friction members is greater than a width of the friction member.

Abstract: A railway wheel includes: a wheel including a plate portion; and a brake disc including a circular plate portion whose front face side is a sliding surface, and a plurality of fin portions which are radially projected on a back face of the circular plate portion, wherein two of the brake discs are fastened in a region within the sliding surface. Regarding an area of a section crossing a space between the brake disc and the wheel along a circumferential direction, a minimum section portion in which the sectional area is minimum is present in a region formed by an outer peripheral surface of the circular plate portion and an inner peripheral surface of the rim portion, and the outer peripheral surface of the circular plate portion follows the inner peripheral surface of the rim portion in a region extending to the outer side from the minimum section portion.

Abstract: A disclosed brake lining includes first and second friction member blocks, fastening members, spring members disposed in the fastening members, and a base plate. Each of the first friction member blocks including friction members is elastically fastened to the base plate by two of the fastening members that pass through the spring member and a first back plate. The two of the fastening members are disposed along a circumference of a circle centered around an axle. Each of the second friction member blocks including friction members is elastically fastened to the base plate by three of the fastening members that pass through the spring member and a second back plate. Two of the fastening members lying on opposite ends of each of the second friction member blocks are disposed along a circumference of a circle around the axle.

Abstract: A railway brake lining includes one or more primary friction members, one or more secondary friction members, and a base plate. Each of the primary friction members is elastically fastened to the base plate. Each of the secondary friction members is fixed on the base plate. A minimum distance between the friction members and a center of an axle is denoted by r1, and a maximum distance between the friction members and the center of the axle is denoted by r2. The centers of one or more of the primary friction members are located in an area that is at a distance of {r1+(r2?r1)/3} to {r1+2×(r2?r1)/3} from the center of the axle. The total slide contact area T1 of the primary friction members and the total slide contact area T2 of the secondary friction members satisfy 2/25?T2/(T1+T2).

Abstract: A railway wheel includes: a wheel including a plate portion; and a brake disc including a circular plate portion whose front face side is a sliding surface, and a plurality of fin portions projected on a back face of the circular plate portion, wherein two of the brake discs are fastened in a region within the sliding surface. Regarding an area of a section crossing a space formed between the brake disc and the wheel along a circumferential direction, a minimum section portion in which the sectional area is minimum is present closest to the back face within the outer peripheral surface of the circular plate portion within a region formed by an outer peripheral surface of the circular plate portion and an inner peripheral surface of the rim portion, and an area of the minimum section portion is not less than 2500 mm2 and not more than 7000 mm2.

Abstract: In a disc brake for a railway vehicle includes a friction member facing a frictional surface of a disc fixed to a wheel or axle of the vehicle. A base plate holds the member on a front surface and a guide plate is at the center of a back surface of the base plate and accommodated in a concave portion of the caliper arm. A base plate front surface is in parallel to a frictional surface of the member. A thickness of the base plate is larger on an inner circumferential side than an outer circumferential side. A thickness of the guide plate is smaller than a depth of the concave portion of the caliper arm. In a state where the frictional surface of the member faces the frictional surface of the disc in parallel, the guide plate is fitted, with play, into the concave portion of the caliper arm.
