Abstract

The invention provides a brake disc and a railway vehicle with the brake disc. The brake disc comprises a disc main body and supporting blocks which are arranged on the disc main body, wherein the disc main body is made of a carbon-ceramic material; the supporting blocks are made of a carbon-carbon material; the brake disc is fully combined with excellent friction and wear performance of the carbon-ceramic material and excellent high temperature mechanical properties of the carbon-carbon material, so that the brake disc is stressed uniformly during a braking process; the safety coefficient of a brake device of the railway vehicle is greatly increased; and the weight reducing effect is remarkable. According to the brake disc disclosed by the invention, the problem that the brake disc in the prior art cannot meet the braking requirement on running of the railway vehicle is solved.

Description

Technical field [0001] The present invention relates to the field of vehicle braking, in particular, to a brake disc and a rail vehicle having the same. Background technique [0002] With the continuous expansion of the scale of urbanization in my country, urban rail transit has achieved unprecedented rapid development, and subway technology will develop in a safer and faster direction. It proposes higher braking efficiency and better safety for brake friction materials. And reliability, more demanding environmental adaptability and other requirements. [0003] However, the brake discs in the prior art cannot meet the braking requirements of rail vehicles. Summary of the invention [0004] The main purpose of the present invention is to provide a brake disc and a rail vehicle having the same, so as to solve the problem that the brake disc in the prior art cannot meet the braking requirements of the rail vehicle operation. [0005] In order to achieve the above objective, according to...
