The invention relates to a railway freight car braking system, which is applied to each vehicle of a railway freight car, and comprises an electric control air braking device used for converting air energy into mechanical energy to brake the vehicle according to an electric control signal; the vehicle control device is used for being electrically connected with a main control device of the railway wagon, electrically connected with the electric control air brake device and used for controlling the electric control air brake device to brake according to a brake control instruction sent by the main control device; and the self-power-generating device is electrically connected with the electric control air braking device and the vehicle control device and used for supplying power to the electric control air braking device according to the braking instruction of the vehicle control device. The self-power-generating devices are arranged on the vehicles to supply power to the electric control air braking devices, the vehicle control device controls the self-power-generating devices to supply power to the electric control air braking devices according to the braking control instructions and controls the electric control air braking devices to conduct braking, vehicle marshalling increasing and coordination are facilitated, and vehicle marshalling quality is improved. And the restriction of locomotive output power is avoided.
Description
technical field [0001] The invention relates to the technical field of railway freight cars, in particular to a railway freight car braking system. Background technique [0002] Braking technology is one of the key technologies of railway freight cars, and its development level determines the train marshalling capacity, operation safety performance, operation efficiency and operation and maintenance performance. The domestic braking technology adopts the traditional air braking system, and the power source and control command are compressed air (ie, air-air mode). After years of hard work, through the update and iteration of GK air brake system, 103 air brake system and 120 (120-1) type air brake system, the train traction capacity has also developed from 3000t and 5000t to 10000t unit, combined 2 million t level. Due to the limitations of the air brake system, although it can meet the normal operation requirements of general freight trains, it exposes many problems in hea...
