Embodiment Construction

[0012] The present invention is described with reference to the drawings.

[0013] The elastic support sheet of the present invention comprises a spherical support surface part (11), a central guide hole part (12), and a fixed support ratchet part (13).

[0014] The amount of elastic deformation of the elastic support sheet of the present invention depends on the forming process and heat treatment process of the high temperature resistant stainless spring steel material.

[0015] Depend on image 3 A cross-sectional view of the floating structure of a single friction block is given. There are multiple friction blocks (2) on the back plate (3) of the brake pad to connect the positioning holes (33), and the positive plate of the back plate has multiple spot-faced holes for the support plate. (31), there are a plurality of spring clips spot facing holes (32) on the back side of the backboard. The fixed support pawl (13) of the elastic support piece (1) is placed in the spot-fac...

Abstract

The invention discloses an elastic support sheet, which comprises a spherical support surface part, a central guide hole part and a fixed support pawl part, wherein the spherical support surface part is used for supporting the support spherical surface of a brake lining friction block body; the central guide hole part is used for guiding a guide connecting shaft of the brake lining friction block body into a friction block body positioning hole on a brake lining back plate; and the fixed support pawl part is arranged in a support ream flat hole on the front face of the brake lining back plate. Due to the adoption of the elastic support sheet, the brake lining friction block body can be freely adjusted in the spherical support surface of the elastic support sheet, and the floating function of the friction block is obtained.

Description

technical field [0001] The invention relates to an elastic support sheet, in particular to an elastic support sheet for enabling the friction block of a brake pad to freely adjust its working position to generate a floating function and to balance braking pressure. Background technique [0002] In the train disc brake system, the brake pad is one of the key components, which directly rubs against the brake disc to absorb kinetic energy to make the train stop. Therefore, it is necessary to ensure the maximum effective friction area between the brake pad and the brake disc. [0003] The existing installation methods of brake pads are mostly riveting, dovetail groove insertion, etc. This kind of installation method is not conducive to the adjustment of the position of the brake pads during the braking process, so as to reduce the running-in time of the brake pads and obtain the perfect balance between the brake pads and the brake disc. Maximum effective friction area. In the ...
