Abstract

The application relates to an air braking device, system and method for a railway wagon. The air braking device of the railway wagon comprises a main controller and a plurality of vehicle-mounted control devices. The main controller is arranged on a freight car adjacent to the locomotive; the vehicle-mounted control devices are arranged on the freight cars respectively and correspond to the freight cars in a one-to-one mode. Each vehicle-mounted control device comprises a wireless communication device and a slave controller connected with the wireless communication device. Braking and relieving actions are carried out through vehicle-mounted control equipment arranged in each freight car, so that the synchronism of train braking and relieving is improved, the longitudinal impact force between vehicles in the train is reduced, the running safety of the vehicles is ensured, and the traction tonnage of the heavy-load train and the grouping number of the vehicles are favorably improved. Nomatter whether an action signal and an air wave signal reach each freight car, the vehicles can be controlled to be braked, and hybrid marshalling with vehicles adopting traditional air braking can be achieved. And meanwhile, no equipment is arranged on the locomotive, so that the dependence on the locomotive is eliminated.

Description

technical field [0001] The present application relates to the technical field of railway freight car braking, in particular to an air braking device, system and method for railway freight cars. Background technique [0002] Railway freight cars generally use the air brake system as their speed regulation and parking control system, which is an indispensable device for vehicle operation. The compressed air in the air brake system is not only the power source for performing the braking action, but also the signal source for the brake control of the front and rear vehicles. Passed backwards, triggering the sequence of vehicles in the train to start braking. [0003] During the implementation process, the inventor found that there are at least the following problems in the traditional technology: the brakes and release actions of the front and rear vehicles in the train are inconsistent, and the impact force between the vehicles is relatively large; Poor adaptability. Conten...
