Document Type and Number:
WIPO Patent Application WO/2021/097935
Kind Code:
A1
Abstract:
An emergency brake extension apparatus for an urban rail vehicle, comprising an emergency brake extension circuit connected to a train power line and positioned in the lead car, and a first emergency brake extension train line (A) and a second emergency brake extension train line (B) passing through the entire train, the emergency brake extension circuit having a protective circuit breaker, an emergency brake button normally-open contact point, and an emergency brake extension relay connected in series; a normally-open contact point of the brake extension relay is connected in series to a bow down control circuit, and a first normally-closed contact and a second normally-closed contact of the emergency brake extension relay are respectively connected in series to a return line (L3) of a train emergency brake control circuit and a power supply negative line circuit (L8); and a third normally-closed contact of the emergency brake extension relay is connected in series to a control circuit of a bypass cutout circuit of a train emergency brake execution circuit. Thus, the problem of urban rail vehicles being unable to synchronously apply emergency braking after connection is solved, and the problem of the emergency brake control circuit of all of the trains being unavailable due to the failure of a given train after connection is avoided.
