An integrated braking system

Abstract

The present invention provides an integrated braking system, which includes: an air source control module, a brake anti-skid module and a communication control module; the brake anti-skid module includes: a first brake anti-skid sub-module and a second brake anti-skid sub-module Modules, the first and second brake and anti-skid sub-modules work synchronously or asynchronously, and any brake and anti-skid sub-module selectively outputs an air source; the air source control module selectively controls the first brake and anti-skid sub-modules. air supply to the module and / or the second braking and anti-skid sub-module; the communication control module selectively communicates the first braking and anti-skid sub-module and the second braking and anti-skid sub-module. The invention changes the vehicle-controlled braking system into a rack-controlled braking system, that is, a rack-controlled integrated brake valve controls one bogie to replace an existing brake control unit to control two bogies of the same vehicle. When a failure occurs, only one bogie fails, reducing the impact on the vehicle and reducing the failure rate by 50%.

Description

technical field [0001] The invention relates to the technical field of rail transit braking, in particular to an integrated braking system. Background technique [0002] For a rail vehicle, when braking is required during operation, the left and right axles of the rail vehicle need to be braked. However, in the existing braking system of rail vehicles, the braking of the bogies of the left and right axles is synchronously controlled, and when the braking system fails, the braking of the bogies of the left and right axles will all fail. Moreover, the existing rail vehicle braking system also has the problem that the rail vehicle pipeline distance is long and cannot be accurately braked. Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0003] The purpose of the present invention is to provide an integrated braking system to overcome the shortcomings in the prior art. [0004] To achieve the purpose of the...
