Abstract

The invention provides a triangular support and a powder metallurgy brake pad with the triangular support and belongs to the technical field of friction linings. A protruding ball face connected witha steel back is arranged on the upper surface of the triangular support, multiple positioning pillars are arranged around the protruding ball face, and the multiple positioning pillars are rotationally and symmetrically arranged around the center of the protruding ball face. An extending end extending out in the direction away from the protruding ball face is arranged between every two adjacent positioning pillars, wherein a spherical face groove connected with a friction block is arranged on the lower surface of the extending end. By means of the triangular support, the multiple positioning pillars are arranged on the upper surface and are rotationally and symmetrically arranged, it can be ensured that the environments where the friction blocks are located on the triangular support are consistent, stress and heat transfer of the friction blocks during braking are uniform and consistent, and therefore eccentric wear of the friction blocks is relieved.

Description

technical field [0001] The invention relates to the technical field of friction linings, in particular to a triangular bracket and a powder metallurgy brake pad having the same. Background technique [0002] The EMU braking system requires that the brake pads should have the properties of wear resistance, heat resistance and stable friction coefficient. The brake pads mainly include: steel back, friction block, triangular bracket and butterfly circlip. Wherein, the triangular support is arranged between the steel back and the friction block, and is used for linking up and down in the brake pad structure. [0003] The triangular support includes a spherical surface, a guide post, a positioning post and a spherical groove of the brake pad. The upper surface of the triangular support is spherically fitted with the concave spherical surface on the steel back, and is positioned with the steel back by a positioning pin. The lower surface of the triangular support It is connected ...
