Abstract

The invention discloses a train braking device, system and method. The device comprises a vehicle controller and a brake executing mechanism. The vehicle controller is used for receiving a brake instruction and controlling the brake executing mechanism to execute braking according to the brake instruction; and the brake executing mechanism is used for generating braking force by adopting a motor driving mode based on the control of the vehicle controller and amplifying the braking force to finish braking. The technical problems that in the prior art, air pressure is adopted for train braking,train components are prone to being damaged, and braking is inaccurate are solved.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a braking device, system and method for a train. Background technique [0002] In order to ensure the safety of train operation, the train will be equipped with braking devices, which generally include air control valves, air cylinders, brake cylinders, pipeline connection devices, foundation braking devices, etc. The brake systems of all vehicles in the train are connected to the front and rear vehicle brake systems through hose connectors at both ends of the vehicle. When braking, the locomotive driver manipulates the gate to reduce the pressure of the train pipe, and the pressure of the train pipes of the rear vehicles also decreases accordingly. The air control valve in the vehicle braking system acts to communicate with the auxiliary air cylinder and the brake cylinder, and the brake cylinder is filled with air. Drive the action of the basic brake device to increase the frict...
