Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Please refer to figure 1 , figure 1It is a working principle diagram of the gas circuit structure in a specific embodiment provided by the present invention.

[0032] In a specific embodiment provided by the present invention, the "dual mode" in the dual-mode braking control system refers to the individual braking mode of the individual braking system and the backup braking mode of the backup braking system, the two modes The switching of the gas path...

Abstract

The invention discloses a dual mode brake control system of a locomotive. The dual mode brake control system of the locomotive comprises a relay valve and a pressure equalization controller, and further comprises a mode change-over valve, an electrical interlocking change-over cock and a brake controller. When the electrical interlocking change-over cock is in a triggered state, the air inlet and the air outlet thereof communicate with each other, otherwise the air inlet and the air outlet thereof are cut off; and when the electrical interlocking change-over cock is triggered, the brake controller enables the air outlet and the second air inlet of the mode change-over valve to communicate with each other, otherwise the air outlet and the first air inlet of the mode change-over valve are enabled to communicate with each other. In this way, the brake controller can control the braking modes of the mode change-over valve under the state change-over of the electrical interlocking change-over cock, and thus free switching between the independent braking mode and the backup braking mode can be realized. Compared with the prior art, a backup brake controller as well as an additional air circuit does not need to be separately provided for the backup braking mode, so that an extra space is not occupied, and wiring complexity of the brake system is lowered. The invention also discloses the locomotive comprising the dual mode brake control system. The beneficial effects are as above.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to a dual-mode brake control system for locomotives. The invention also relates to a locomotive comprising the dual mode brake control system described above. Background technique [0002] With the development of rail transit in China, more and more rail locomotives have been widely used. [0003] A locomotive is a self-propelled vehicle that pulls or pushes railway vehicles and does not carry a commercial load. The locomotive uses the power generated by steam engine, diesel engine, traction motor or other power machinery, and drives the driving wheel (drive wheel) through the locomotive transmission device, and generates driving force by means of the adhesion between the driving wheel and the rail, that is, the traction force of the locomotive. The traction generated by the locomotive overcomes the resistance of the train and can drag a train that is 10 or 20 times larger tha...
