Embodiment Construction

[0038] The brake system of the present invention is a simulated direct air brake system controlled by a microcomputer. It works in coordination with the electric brake during normal braking, and has the functions of emergency braking, holding brake and parking brake at the same time. The specific structure diagram is shown in figure 1 .

[0039] The air source of the air braking system of the present invention is an air supply module, which is integrated in a frame and elastically suspended under the underframe of the vehicle body. The air supply module can provide clean and dry compressed air for the brake system and other air-consuming parts of the vehicle. Its schematic diagram is as follows figure 2 As shown, an AC380V three-phase AC motor 1 drives an air compressor 2 with a rated displacement of 320L / min, which forms dry and clean compressed air after passing through a double-tower dryer and an air filter. The safety valve 3 is used to prevent the output compressed ai...

Abstract

The invention discloses an air brake system for an automatic program management (APM) vehicle. In order to solve the problems that an existing air brake system does not have the functions of brake control, brake monitoring and fault diagnosis, the air brake system for the APM vehicle comprises an air supply module, an air control module, a brake control module, a basic brake device air circuit control module, an air spring air circuit control module, and an uncoupling and vehicle connection pipeline control module. Compared with the prior art, the air brake system has more flexible brake cylinder pressure regulating capability, and better control precision and function extensibility.

Description

technical field [0001] The invention relates to the field of urban rail vehicle braking systems, in particular to an air braking system for APM vehicles. Background technique [0002] At present, the domestic existing APM vehicle brake system does not have a brake electronic control unit, and the ATC directly sends the brake control signal to the electromagnetic proportional valve in the brake control module for electrical-mechanical conversion. The manufacturing process of the analog electro-pneumatic conversion solenoid valve is complicated, the price is high, and the cleanliness of the compressed air is highly required. [0003] Since there is no brake electronic control unit, the system does not have the functions of brake control, brake monitoring and fault diagnosis, and cannot be expanded. Contents of the invention [0004] Aiming at the deficiency that the existing air brake system does not have the functions of brake control, brake monitoring and fault diagnosis,...
