Abstract: A startup device includes a starting motor, a drive gear mounted on an output shaft of the starting motor, a transmission mechanism, and a fly wheel. The transmission mechanism further includes a first gear engaging with the drive gear, and at least three second gears, each being disposed on an end face of the first gear through a unidirectional overrunning clutch. Each unidirectional overrunning clutch is mounted on a mounting shaft disposed on the end face of the first gear. The startup device further includes a third gear disposed on and end face of the fly wheel and engaged with the third gears.

Abstract: A hybrid power driving system includes an engine including a crankshaft; and a dual clutch transmission system coupled to the crankshaft. The dual clutch transmission system includes a first clutch, a second clutch, and a transmission. Both the first and second clutches are connected with the crankshaft. The transmission includes a first input shaft connected with the first clutch, a second input shaft connected with the second clutch, shifting gear sets, where each shifting gear set includes at least a stationary gear and a free gear; and an output shaft having one end coupled with a differential. The other end of the output shaft is connected with a driving electric motor. The driving electric motor drives the output shaft directly.
