Mechanical brake system for urban rail vehicles and motor train units

Abstract

The invention discloses a mechanical brake system for urban rail vehicles and motor train units, which belongs to the field of brake systems and solves the problems of complex structure, high manufacture cost and more difficulty in installation and disassembly of the traditional brake system because of the limits from the installing space of the brake disc. The mechanical brake system comprises a brake disk installing seat sleeved on an axle, wherein the brake disk installing seat is circumferentially provided with at least two brake disks, at least one brake lining for braking the brake disks under the action of a brake force F is arranged outside the brake disks, and the brake lining is arranged on a bogie frame of a rolling stock. The rolling stock is braked by using a mode of converting kinetic energy of the rolling stock into heat energy, the mechanical brake system disclosed by the invention has the advantages of reliability for braking, simple structure, low manufacture cost, convenience for installation and disassembly, convenience for maintenance, and the like; and huge economic benefit can be generated. The invention has a wider application prospect.

Description

technical field [0001] The invention relates to the field of braking systems, in particular to a mechanical braking system for urban rail vehicles and train sets. Background technique [0002] The basic braking components of urban rail transit vehicles and high-speed EMUs are an essential and important part of them. The merits and demerits of the braking performance of the braking components and the maintainability of the components are the main design basis of the braking system. The basic braking system of existing rail transit locomotives and vehicles can be roughly divided into two types: brake shoe brakes and disc brakes, wherein disc brakes can be divided into wheel disc brakes and axle disc brakes. For brake shoe The braking system achieves braking through the brake pads installed on the locomotive bogie frame close to the wheels, which is characterized by low braking efficiency and cannot meet the braking requirements of trains under high speed and heavy load condit...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the defects of the existing shaft-disc brake system that is limited by the installation space of the brake disc, the structure is complex, the manufacturing cost is high, and the installation and disassembly are relatively difficult, the present invention aims to provide a mechanical brake system for urban rail vehicles and EMUs. system, the braking system realizes the braking of the train through the way that the roller brake discs are fitted with the brake shoes
