Title:
AUXILIARY RESERVOIR AIR CHARGE SYSTEM AND EXPRESS FREIGHT TRAIN AIR BRAKE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/039957
Kind Code:
A1
Abstract:
The present application relates to the field of air brake systems, and provides an auxiliary reservoir air charge system and an express freight train air brake system, aiming at mitigating the problem that air charge of an auxiliary reservoir is limited by air charge of a control reservoir. The auxiliary reservoir air charge system comprises a control reservoir air charge valve, a control reservoir, an auxiliary reservoir air charge valve, a first passage, and a second passage; the control reservoir air charge valve is provided with a train line air outlet, the control reservoir is provided with a first train line air charge port, and the auxiliary reservoir air charge valve is provided with a second train line air charge port; the first passage is communicated with the train line air outlet and the first train line air charge port, and the second passage is communicated with the train line air outlet and the second train line air charge port; and the first passage and the second passage are connected in parallel. The express freight train air brake system comprises the auxiliary reservoir air charge system. Air is simultaneously charged to the control reservoir and the auxiliary reservoir air charge valve by means of the first passage and the second passage, the auxiliary reservoir air charge valve charges air to the auxiliary reservoir, and air charge of the auxiliary reservoir charge valve is independent from that of the control reservoir and is not limited by the air charge of the control reservoir.
