hybrid drive train

Abstract

The invention discloses a hybrid-driven railcar train. The hybrid-driven railcar train comprises a power compartment, a power supply system, a driven compartment, a power compartment running mechanism, a driven compartment running mechanism traveling mechanism, an active kinetic potential storage and transportation circuit and motor composite driving system, a passive potential energy storage andtransportation circuit, a controller and a super capacitor group, and the hybrid driving of the railcar train is realized by recovering the kinetic energy of the train braking process. The hybrid-driven railcar train has the advantages of good starting performance, high energy efficiency, less system heat generation and long service life.

Description

technical field [0001] The invention belongs to the field of train driving, and in particular relates to a hybrid-driven rail train. Background technique [0002] Rail trains refer to vehicles running on railway tracks, mainly including rail vehicles such as light rail, subway, bullet train, high-speed rail, truck and ordinary train, usually composed of multiple carriages, and the carriages are divided into bullet train carriages and trailer carriages. According to the load, rail trains can be divided into freight wagons and passenger wagons, and there are also passenger wagons with both. [0003] Taking EMUs as an example, my country's EMUs are mainly divided into three categories, namely, high-speed EMUs, general EMUs, and low-speed EMUs. The EMU working system mainly includes mechanical system, electrical system and hydraulic and pneumatic system. The mechanical system is mainly used for the running of the EMU and energy transmission. Auxiliary control of the power syst...

Problems solved by technology

[0004] The operation of the EMU generally requires a lot of power, which requires a large volume of the motor, which makes the reasonable arrangement of the motor in the EMU system extremely difficult; in addition, the EMU has a large mass, fast running speed, and a large number of motors. During its operation, frequent acceleration and deceleration are required. When the EMU decelerates, braking resistors are generally used to convert the kinetic energy of the EMU into heat energy for consumption. When emergency braking is required, the EMU uses brake discs to brake, and a large amount of heat will be generated on the brake discs. , this will not only cause a waste of energy, but also cause the overheating of the brake disc to affect the braking efficiency, thereby affecting the safety of the EMU brakes; when the EMU starts, the instantaneous peak power of the motor is very high, and the motor generates a high starting current during the start process. Generate a lot of heat and affect the service life of the motor
