MAIN AND AUXILIARY TRANSMISSION SYSTEMS OF DIESEL LOCOMOTIVE AND DIESEL LOCOMOTIVE

摘要

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 system.
