HYBRID VEHICLE TRANSMISSION SYSTEM

Номер: WO2020037840A1
Автор: WEN, Jibin, WEI, Hong, FAN, Jiake, LAI, Haozhe, SONG, Xinliang, ZOU, Xiaowei
Принадлежит:

A hybrid vehicle transmission system comprises a generator (203), a controllable rectifier (204), an inverter (205) and an electric motor (206). A power input terminal of the generator (203) is configured to be connected with a crankshaft of an engine (202) so that the generator (203) converts a mechanical motion input by the engine (202) into a first alternating current. an electric output terminal of the generator (203) is connected with an alternating current terminal of the controllable rectifier (204), and a direct current terminal of the controllable rectifier (204) is configured to be connected with a power battery (207). The controllable rectifier (204) rectifies the first alternating current according to a first control signal to output a first direct current of a magnitude corresponding to the first control signal so that a terminal voltage of the power battery is the same with the direct current terminal voltage of the controllable rectifier; and a direct current terminal of ...

Принадлежит:

A main and auxiliary transmission system of an internal combustion locomotive, comprising a locomotive internal combustion engine (21), a generator (22), a main rectifying device (23), a main intermediate direct-current circuit (24), a main transmission system (25), an auxiliary converter device (26), an auxiliary intermediate direct-current circuit (27), an auxiliary transmission system (28), a power battery charging and discharging device (29) and a power battery (30). In the system, when the generator (22) stops generating electricity due to the failure of the main transmission system (25), the power battery (30) is used to power the auxiliary transmission system (28), enabling the auxiliary transmission system (28) to be able to operate normally for a period of time when the main transmission system (25) fails, thereby gaining time for the troubleshooting and recovery of the main transmission system. Further provided is an internal combustion locomotive comprising said transmission ...
