Particular/special requirement, the prior art needed for such as climbing load in the case of large torque, often shows in special operational process
It is bad even to shut down, especially loaded under conditions of vehicle needs premised on speed unable to do what one wishes, unique solution is
Amplifying power.
To solve the performance strength of vehicle bigger in operation, Dual-motors Driving pattern has been begun attempt in field, such as
Say wheel hub motor, when single motor undercapacity, start auxiliary-motor work, but this designing scheme is the list for sacrificing normal operation
Electric efficiency is preceding topic.Therefore, technical staff will start to expand side-mounted high-speed electric expreess locomotive research, such as Patent No.
The driving device Chinese invention patent of 200610138450.2 electric motor car with two wheels, just proposed major-minor motor and drives actively before 10 years
The transmission scheme of gear, the technology employ main motor and auxiliary-motor output shaft and are nibbled respectively by respective gear with drive gear
Close, but this primary transmission can not allow auxiliary-motor to perform to more speed and bigger output torque due to the limitation of gearratio（Most
Big output torque is 70n.m）, since major-minor motor is arranged to same direction, in order to make major-minor motor reasonable installation, it has to allow
The unit volume of gearbox increases and increases production cost, which, which additionally uses after axis 9 extends vehicle frame, passes through one-way shaft
Hold 8, bearing 7,5 to be connected with a drive gear 6 so that by drive gear 6 axis 9 can only be driven to rotate, and 9 band of axis cannot be made
Dynamic drive gear 6 rotates, but this technology can not be realized in practical applications, and technical staff should be distinctly understood that, in
Axis 9 is fixedly connected with drive gear 6, although vehicle, in reverse drive, axis 9 is synchronous fortune all the time with drive gear 6
It is capable, and can not realize and slide when depart from magnetic resistance.
