Abstract

After many years of operation practice and academic research, the author found that after the 1800 meter long heavy haul train had emergency braking, the dangerous "vehicle lifting and squeezing moment" was transferred from the head to the tail of the train one by one, which was called "wall collision effect" in the passenger service; Especially for combined trains, the phenomenon of vehicle lifting and squeezing is particularly obvious, Especially for combined trains, the phenomenon of vehicle lifting and squeezing is particularly obvious, and the derailment probability of locomotives in the middle increases greatly, which seriously threatens the operation safety of overlong heavy haul In this paper, the author boldly breaks through the traditional thinking and creatively puts forward a new idea that the braking torque of super long heavy haul train transforms the existing extrusion emergency braking parking from the front to the back should be generated the more safe " stretching state" parking from the rear stretching state" parking from the rear to the front, changing the transmission direction of the braking torque from "front to back" to "back to front", which greatly reduces the derailment coefficient of the super long heavy haul train under the emergency braking condition.
