Abstract

The invention relates to a railway train and an empty and load adjusting device and method for an electric braking system. The empty and load adjusting device for the electric braking system comprises a displacement sensor and a vehicle controller. The displacement sensor is used for being arranged on a vehicle unit of a railway train and used for measuring deflection parameters of a bogie of the vehicle unit. And the vehicle controller is in communication connection with the displacement sensor, and the vehicle controller is used for obtaining the load state of the vehicle unit according to the deflection parameter and adjusting a brake control instruction transmitted by the bus according to the load state. Thus, it is ensured that the braking force of each vehicle unit is matched with the current load state, the vehicle units output large braking force when being fully loaded, and the vehicle units output small braking force when being unloaded, and therefore the ratio of the braking force output by each vehicle unit to the sum of the self weight and the load of the vehicle units in the load state is basically constant; longitudinal impulse between the vehicle units is reduced, and braking safety is improved.

Description

technical field [0001] The invention relates to the technical field of railway trains, in particular to a railway train, an empty-load vehicle adjustment device and a method for an electric braking system. Background technique [0002] When braking a railway train, the braking force needs to match the actual load state of the vehicle. A larger braking force is required for a heavy vehicle, and a smaller braking force is required for an empty vehicle, so that the vehicle can be kept within the specified limit. Complete parking, and will not cause wheel rubbing failure due to excessive braking force. [0003] Most of the traditional railway trains use the air system for braking. When braking, the control valve acts to make the pressure air in the air storage cylinder flow to the brake cylinder through the control valve channel. The pressure of the brake cylinder rises, pushing the piston out to drive and connect with it. The lever system acts to make the brake shoe press the ...
