At the same time, people require also more and more higher to the power performance and bearing capacity of electric automobile.In this context,
On the one hand, in power of motor it is difficult on the basis of having very big lifting, two-shift automatic speed variator has increasingly been used for electronic vapour
Che Zhong；On the other hand, motor light weight high speed is an inexorable trend of motor development：In electric drive assembly output torque
, can equal proportion reduction motor torque need by improving motor and decelerator maximum speed under power constraint independent of time
Ask, so as to reduce motor volume and weight, improve power density level.Therefore, how the drive of existing ripe light weight high speed
Dynamic motor and two-shift automatic speed variator integrate, and the power assembly of high torque are formed, so as to improve the dynamic property of electric automobile
Energy and load capacity, turn into the problem of in the urgent need to address at present.
Utility model content
In order to overcome the disadvantages mentioned above of prior art, the utility model provides a kind of bi-motor input two-gear automatic speed changing and passed
Dynamic system, it can change the travel speed of vehicle and the bearing capacity of vehicle in controller control range, by Dual-motors Driving, adopt
With major-minor case structure, odd-side is symmetrical expression high deceleration case, and main tank is two gear casees of double intermediate shaft types, is passed so as to substantially increase
The power performance and load capacity of dynamic system.
Technical scheme is used by the utility model solves its technical problem：A kind of bi-motor inputs two-gear automatic speed changing
Transmission system, by Dual-motors Driving, including main tank and odd-side, wherein odd-side is provided with two input shafts and a master subtracts axle, main
Case is provided with two jackshafts and an output shaft；Motor is by spline and two input axis connections, on two input shafts

Engage, be separately provided with jackshaft bottom gear gear 9 on jackshaft 10, two jackshaft bottom gear gears 9 are respectively with empty set defeated
Output shaft bottom gear gear 15 on shaft 16 engages.
Sliding gear collar 14 is set on output shaft 16, sliding gear collar 14 with it is main subtract axle constant mesh gear 7 and combined when, then be height
Speed gear, then it is bottom gear when sliding gear collar 14 is combined with output shaft bottom gear gear 15.
The main tank 5 is two gear casees of double intermediate shaft types, and odd-side 6 is symmetrical expression high deceleration case.
The utility model is inputted using bi-motor, increases the input torque of transmission system；Subtracted at a high speed using the symmetrical expression of odd-side 6
