Abstract

The invention discloses a brake pressure control device and method, a pressure needed by service braking is set through a main adjusting valve, when a load is loaded, the output pressure of an auxiliary reducing valve is supplied to the main adjusting valve for pressure supplement by taking an electromagnetic valve as a carrier, and the brake pressure is increased; stepless change of final output pressure of the main regulating valve can be achieved by controlling connection and pressure maintaining functions of the electromagnetic valve through the controller, and when brake pressure needs to be released rapidly, rapid exhaust is achieved to the maximum extent through an internal one-way valve air channel, and internal throttling of the main regulating valve is avoided. The interior of the remote relief pneumatic control valve and the interior of the brake limiting pneumatic control valve are in a piston type, use is safe and reliable, and response is rapid in function; the internal structure of the brake pressure control device is simplified, the running safety of the vehicle is improved, and a user can conveniently maintain and overhaul the vehicle; in order to meet various use environments of the vehicle, brake limiting and remote relieving functions can be achieved.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a braking pressure control device and method. Background technique [0002] With the modernization of domestic cities and the development of transportation, my country's urban rail vehicles play an increasingly important role in urban transportation. The "14th Five-Year Plan" pointed out in the "Suggestions" for rail transit: coordinate the promotion of infrastructure construction. Accelerate the construction of a transportation power, improve comprehensive transportation channels, comprehensive transportation hubs and logistics networks, accelerate the network of urban agglomerations and metropolitan circles, and increase the depth of transportation in rural and border areas. [0003] At present, there are mainly two types of braking systems commonly used in urban rail transit: frame-controlled braking systems and vehicle-controlled braking systems. The brake control device in t...
