Integrated control type braking system of railway wagon

Abstract

The invention relates to an integrated control type braking system of a railway wagon. The integrated control type braking system comprises a basic braking subsystem, a wind control braking subsystem, an electric control braking subsystem and a manual control braking subsystem which are cooperatively equipped on each wagon, wherein a braking branch pipe of the wind control braking subsystem is connected with a braking cylinder of the basic braking subsystem to realize wind control brake and relief; a braking chain of the manual control subsystem is connected with a manual brake lever of the basic braking subsystem to realize manual control and relief; and a branch cable of the electric control braking subsystem is connected with an air braking valve of the wind control braking subsystem to realize synchronous brake and synchronous relief of the basic braking subsystem of each wagon. The integrated control type braking system disclosed by the invention adopts an intelligentized, modularized and integrated design, has the advantages of simple and stable structure, compact and reasonable layout, short braking distance, high braking efficiency, capability of realizing synchronous brake and relief, and safety and reliability, thereby being capable of improving the wagon traveling speed, lightening the longitudinal impact of the wagon and meeting the demands of normal operation of a high-speed overloaded railway wagon.

Description

technical field [0001] The invention relates to a railway vehicle brake system, in particular to an integrated control brake system for railway freight cars. Background technique [0002] High-speed and heavy-duty transportation is an effective way to improve railway freight capacity, and it is also the main development direction of railway wagon technology in the world today. At the same time, higher requirements are put forward for the braking technology of railway wagons. The braking system on high-speed heavy-duty trucks not only needs to solve the problems of braking distance limit, longitudinal dynamic performance, and braking safety in areas with long slopes, but also requires higher braking efficiency and better braking performance. Ease performance, and a simpler and more reliable structural layout. [0003] However, most of the existing railway freight cars in our country adopt the braking system composed of the traditional air brake and the lever transmission mec...

AI Technical Summary

Problems solved by technology

Brake cylinders, brake regulators and part of the rod system structure are arranged on the car body, and the braking force is transmitted and enlarged through the whole set of rod system connection mechanisms arranged on the car body and the bogie. , low braking efficiency, poor braking mitigation performance, and there are certain safety hazards

Especially for bathtub cars, funnel cars, concave bottom cars and other car bodies with special structural chassis, the arrangement of the braking system is more difficult, the braking distance is long, the braking efficiency, the braking relief is poor and the failure Defects with a high rate can never be fully resolved

Therefore, it is difficult to adapt to the high requirements for the safety and reliability of the braking system of high-speed heavy-duty trucks
