Secondary pass through the first free gear 5, the first idler gear 12, the gear 9 of the 4th idler gear 15 and output shaft 16 is delivered to output
On axle；The power of the second motor 2 passes sequentially through the 3rd free gear 8, the 3rd idler gear 14, the 4th idler gear 15 He
The gear 9 of output shaft 16 is delivered on output shaft；First motor 1 and the second driving are adjusted by motor control system
Motor 2 torque output can be realized both moments of torsion and participate in ratio, thus allowing the first motor 1 and second drive electricity as far as possible
Machine 2 works in high efficient district in vehicle low speed.
Situation 2：Middling speed bi-motor pattern
As shown in figure 3, the first combined cover 7 slides to right side, the second combined cover 10 slides to right side；The power of the first motor 1 according to
Secondary pass through the second free gear 6, the gear 9 of the second idler gear 13 the 4th idler gear 15 and output shaft 16 is delivered to output shaft
On；The power of the second motor 2 passes sequentially through the 3rd free gear 8, the 3rd idler gear 14, the 4th idler gear 15 and defeated
The gear 9 of shaft 16 is delivered on output shaft；First motor 1 and second is adjusted by motor control system and drives electricity
Machine 2 torque output can be realized both moments of torsion and participate in ratio, thus allowing the first motor 1 and the second motor as far as possible
2 work in high efficient district in vehicle middling speed.
Situation 3：High speed bi-motor pattern
As shown in figure 4, the first combined cover 7 slides to right side, the second combined cover 10 slides to left side；The power of the first motor 1 according to
Secondary pass through the second free gear 6, the gear 9 of the second idler gear 13 the 4th idler gear 15 and output shaft 16 is delivered to output shaft
