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.

Brake lining for railway vehicle

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.

Brake lining for railroad vehicle

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.
