Locomotive air braking system and locomotives

Abstract

The invention provides a locomotive air braking system and locomotives. The locomotive air braking system comprises a braking cylinder and a control air pipe, a piston of the braking cylinder divides a cylinder body of the braking cylinder into a first cavity and a second cavity, and the first cavity is provided with a first air pipe port communicated with the control air pipe; the locomotive air braking system further comprises a train air pipe and an air-control reversing valve, the second cavity is provided with a second air pipe port, the air-control reversing valve is provided with a relieving air way and a braking air way, the relieving air way is communicated with the train air pipe and the first air pipe port respectively and used for enabling air of the train air pipe to enter the first air pipe port, the braking air way is communicated with the train air pipe and the second air pipe port respectively and used for enabling the air in the train air pipe to enter the second air pipe port, a first control switch is arranged between the first air pipe port and the control air pipe, and a second control switch is arranged between the train air pipe and the air-control reversing valve. Therefore, the air braking system is suitable for both large-tonnage locomotives and small-tonnage locomotives.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a locomotive air brake system and a locomotive. Background technique [0002] At present, in domestic subway shield tunneling construction, locomotives such as industrial and mining vehicles, mortar trucks, and muck trucks are important auxiliary transportation equipment, which undertake the material transportation work during the tunneling process of shield machines. [0003] The air brake system on the locomotive is generally a single-acting cylinder air brake system, that is, a single-acting brake cylinder is used for braking. The single-acting brake cylinder mainly includes a piston and a spring. The piston separates the cylinder body of the brake cylinder into a first chamber and a second chamber. The spring is located in the second chamber. The first chamber has an air pipe interface, and the air pipe interface Connect to the control air duct of the vehicle. The control ...
