Problems solved by technology

[0004] At present, the brake pads used in the braking system of passenger vehicles with a speed of 160km/h are powder metallurgy brake pads. When this type of brake pad is used, the energy and heat generated during the braking process will cause damage to the brake disc. Phenomena such as hot spots, cracks, and gullies appear, and the weight of the existing powder metallurgy brake pad is about 12kg, which is inconvenient to install, and the weight of the whole vehicle becomes heavier after installation, because the structure of the powder metallurgy brake pad is de

Abstract

The invention belongs to the technical field of braking systems, and particularly relates to a composition brake pad for a centralized power EMU of 160 KMh. The composition brake pad is composed of afriction body and a dovetail plate, wherein the friction body and the dovetail plate are integrally pressed and formed, the top of the friction body is provided with a groove, the friction body is composed of resin and rubber, and the dovetail plate is a steel plate. A brake pad is replaced with the composition brake pad, a material of the composition brake pad is changed into an organic matter, and the composition of the brake pad is carried out by the resin and the rubber, so that the environmental pollution is effectively reduced, the cost of the brake pad is effectively reduced, and the inconvenience of installation is reduced; and meanwhile, the weight of a whole vehicle is reduced, and also accidents such as breaking, dropping and falling are effectively prevented from occurring by the integrated structural design of the composition brake pad.

Description

technical field [0001] The invention relates to the technical field of brake systems, in particular to a combined brake pad for a 160KMh power train. Background technique [0002] On April 27, 2017, the 160-kilometer-per-hour power centralized EMU (hereinafter referred to as "Dongji EMU") was launched in CRRC Tangshan Company. It is the latest achievement of deepening supply-side reform of my country's railways and improving the service quality of existing railways. It will replace the operation of 25T railway passenger cars (ordinary trains). It is designed to use 1 motor and 7 trailers and 1 control vehicle formation (standard group). The basic braking device scheme is based on the original 25T basic braking. The material is changed from cast iron to cast steel discs, and the problems of eccentric wear of brake pads and cracks of brake discs are optimized. [0003] Two sets of basic braking devices are arranged on each axle of the vehicle. Considering that the EMU adopts ...
