The invention discloses a train brake pad; a plurality of friction blocks are arranged on a back plate; each friction block comprises a friction body and a support body; each support body consists of a plate body, a table body and a pin body; a downward convex spherical face is formed in the middle of the bottom surface of each adjustment seat; each adjustment seat is provided with a middle hole; the upper part of each middle hole is expanded around to form a two-step-shaped spherical face; the friction blocks sit on upper-step spherical faces of the middle holes through the table bodies of the support bodies; a gap is formed between one support body and the top surface of one adjustment seat correspondingly; pin bodies pass through the middle holes in a loosening manner; the upper part of each mounting hole is expanded around to form a concave spherical face; the adjustment seats sit on the concave spherical faces of a mounting seat through the downward convex spherical faces; two locating pins of each adjustment seat are inserted into two corresponding locating holes in the back plate in a loosening manner; a gap is formed between the peripheral edge of the bottom surface of each adjustment seat and the top surface of the mounting seat; spring clamp rings are arranged at the lower parts of the pin bodies; and the friction blocks, the adjustment seats and the back plate are connected in a floating manner by the spring clamp rings. Multidimensional adjustment on the friction blocks is realized, a situation that the surfaces of the friction blocks are in 100% contact with the surface of the train brake pad all the time is ensured, and the eccentric wear problem of train brake pad is solved.

Train brake pad

The invention discloses a novel elastic structural brake pad. The novel elastic structural brake pad comprises a steel back assembly, a locking assembly and a plurality of brake assemblies, wherein the brake assemblies are in connection locking with the steel back assembly by the locking assembly and elastic assemblies are arranged between the brake assemblies and steel back assembly. The novel elastic structural brake pad adopts an elastic structure. A brake block can be automatically retreated and adjusted backward under the braking thrust in a braking process so that a friction surface of the brake block and a brake disk surface can maintain a good fit so as to ensure the stable braking performance. A larger ventilation and heat dissipation gap is left between a brake block framework and a back plate in the brake pad elastic structure to timely discharge heat on parts of the structure and effectively prevent the parts such as the back plate from deformation caused by heat absorptionof brake materials. The structure can also prevent the brake materials from fracturing, edge-dropping and corner-dropping caused by too long braking distance and temperature rise, thereby extending the service life of the brake.
