Title:
DRIVING SYSTEM OF DUAL-MOTOR DUAL-SHAFT INPUT GEARBOX AND GEAR SHIFT CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/202031
Kind Code:
A1
Abstract:
Disclosed are a driving system of a dual-motor dual-shaft input gearbox and a gear shift control method therefor. The system comprises a driving motor I (1), a driving motor II (21) and an electrically controlled mechanical automatic transmission. The electrically controlled mechanical automatic transmission comprises a first gear set (4, 18, 12, 10), a second gear set (17, 6, 7, 15), a third gear set (4, 18, 14, 8), a fourth gear (17), a clutch collar I (16), a clutch collar II (9), a transmission input shaft I (3), a transmission input shaft II (19) and a transmission output shaft (11). The electrically controlled mechanical automatic transmission provides 3 gears for the power output from the driving motor I (1) and the driving motor II (21). By the coupling of the driving motor I (1), the driving motor II (21) and the electrically controlled mechanical automatic transmission and the driving of the driving motor I (1) and the driving motor II (21), the switching between the 3 gears can be achieved. The system saves the vehicle layout space, the gears do not affect each other, the requirements for bearings and gear speeds are not high, and the service life is prolonged.
