Braking system and locomotive

Abstract

The invention provides a braking system and a locomotive including the same. The braking system comprises a main braking device, a back-up braking device, a valve, an equalizing reservoir, and a main air reservoir, a first valve port of the valve is connected with the main braking device and the main air reservoir, a second valve port of the valve is connected with the back-up braking device, and a third valve port of the valve is connected with the equalizing reservoir; when the braking system is in an electrically controlled braking working condition, the valve controls the first valve port and the third valve port to be in a breakover mode, and the second valve to be closed. Accordingly, when the braking system is in the electrically controlled braking working condition, electrically controlled braking work can be completed normally by the braking system through breakover of the first valve port and the third valve port of the valve; air circulation between the equalizing reservoir and the back-up braking device can not be conducted by closing the second valve port, therefore, the pressure value of the air in the equalizing reservoir can be detected accurately, and the pressure value of the air in the equalizing reservoir can be controlled accurately.

Description

technical field [0001] The invention relates to the technical field of locomotive braking, and more specifically, relates to a braking system and a locomotive. Background technique [0002] With the rapid development of my country's rail transportation industry, the safety requirements for locomotives are getting higher and higher; and the braking system of locomotives is a key component to ensure its safety. [0003] The braking system in the prior art mainly includes the main air cylinder, the equalizing air cylinder, the main braking device and the backup braking device, etc., wherein the main air cylinder is respectively connected with the equalizing air cylinder and the equalizing air cylinder through two branch pipes of the same pipeline. The backup brake device is connected to transmit gas to the balance air cylinder, and the branch pipeline where the balance air cylinder is located communicates with the branch pipeline where the backup brake device is located. The w...
