Go out the first calutron 3 and the second electromagnetism by the gear ratio calculation of required electric vehicle running speed and determination
The highest of device 4 exports revolving speed.Assuming that the first output shaft 3a is to resultant gear ratio between power output shaft 5 in wheel hub electric motor of electric vehicle
It is 7, the second output shaft 4a to resultant gear ratio between power output shaft 5 is 11.2.First calutron 3 and the second calutron 4
For identical parameters, such as exporting maximum speed is 3000 revs/min；So the first calutron 3 to outer gear ring 2a input torque and
The revolving speed of power output shaft 5 is 428.57 revs/min when second calutron 4 is in lockup state；Second calutron 4 is to too
The revolving speed of sun wheel 2c input torque and the first calutron 3 power output shaft 5 when be in lockup state is 267.86 revs/min；
Obvious first calutron 3 power output shaft 5 to outer gear ring 2a input torque and when the second calutron 4 is in lockup state
Revolving speed and the second calutron 4 power output shaft 5 to sun gear 2c input torque and when the first calutron 3 is in lockup state
Revolving speed it is unequal.Assuming that the tire outside diameter installed on wheel hub 7 is 420mm.
According to the actual situation, the parameter of the first calutron 3 and the second calutron 4 can not be identical, such as exports highest
Revolving speed, it is only necessary to guarantee the first calutron 3 power to outer gear ring 2a input torque and when the second calutron 4 is in lockup state
The revolving speed of output shaft 5 and the second calutron 4 are moved to sun gear 2c input torque and when the first calutron 3 is in lockup state

Vehicle direction controlling button and running speed control handle.
This wheel hub electric motor of electric vehicle control method is divided into low speed and moves ahead control method, the speed that moves ahead greater than the forward speed of low speed
Two grades of forward control methods, move ahead speed be greater than two grades of forward speed third gear move ahead control method, move ahead speed be greater than three
The high forward control method and low-reverse control method of the forward speed of shelves.
Electric vehicle can neatly select above-mentioned any a variety of forward controlling parties from above-mentioned control method according to actual needs
Method combination executes, such as the forward control method of simultaneous selection low speed, two grades of forward control methods, the forward control method of third gear and high speed
Move ahead control method；The forward control method of low speed, two grades of forward control methods and the forward control method of third gear are for another example only selected, again
Such as two grades of forward control methods, the forward control method of third gear and high forward control method.
The present embodiment is by illustrating that the forward control method of simultaneous selection low speed, two grades of forward control methods, third gear move ahead and control
Method and high forward control method and low-reverse control method processed；And pass through line mode before manipulation electric vehicle linear accelerating
Further illustrate electric vehicle variable speed drive motor, the effect of wheel hub electric motor of electric vehicle and wheel hub electric motor of electric vehicle control method and excellent
Point:
Manipulation direction of traffic control button guarantees that control circuit controls the first calutron 3 and the second calutron 4 and makes at vehicle
In forward traveling.5 revolving speed of power output shaft that sensor monitors when dead ship condition is 0；Rotate running speed control handle extremely
Limit value, this state are line mode before above-mentioned electric vehicle linear accelerating.
After rotating running speed control handle, the forward control method of low speed is initially entered, i.e., control circuit is according to driving speed
Action control the first calutron 3 and the second calutron 4 of degree control handle make the rotation side of outer gear ring 2a Yu sun gear 2c
To opposite；The curved rising of electric current of first calutron 3 and the second calutron 4；The highest of power output shaft 5 under this state
Revolving speed is 160.71 revs/min.
Low velocity threshold is set in control circuit, low velocity threshold is slightly below power output shaft 5 in the forward control method of low speed
Maximum speed, theoretical 160.71 may be not achieved in the maximum speed of electric vehicle power output shaft 5 in actual use after all
Rev/min, if low velocity threshold is 158 revs/min；So the shift speed of the electric vehicle is 12.5km/h.
When 5 revolving speed of power output shaft of monitoring reaches low velocity threshold, into two grades of forward control methods, i.e. control circuit
The second calutron 4 is controlled individually to the sun gear 2c input power of planetary gear set 2, and is controlled at the first calutron 3
In lockup state.The curved rising of electric current of second calutron 4；The maximum speed of power output shaft 5 is under this state
267.86 rev/min.
Middling speed threshold value is set in control circuit, middling speed threshold value is slightly below power output shaft 5 in two grades of forward control methods
Maximum speed, as middling speed threshold value be 265 revs/min；So the shift speed of the electric vehicle is 21km/h.
When 5 revolving speed of power output shaft of monitoring reaches middling speed threshold value, move ahead control method, i.e. control circuit into third gear
The first calutron 3 is controlled individually to the outer gear ring 2a input power of planetary gear set 2, and is controlled at the second calutron 4
In lockup state.The curved rising of electric current of first calutron 3；The maximum speed of power output shaft 5 is under this state
428.57 rev/min.
High Speed Threshold is set in control circuit, High Speed Threshold is slightly below power output shaft 5 in the forward control method of third gear
Maximum speed, as High Speed Threshold be 436 revs/min；So the shift speed of the electric vehicle is 34.5km/h.
When 5 revolving speed of power output shaft of monitoring reaches High Speed Threshold, into high forward control method, i.e. control circuit
Controlling the first calutron 3 and the second calutron 4 keeps outer gear ring 2a identical as the direction of rotation of sun gear 2c, the first electromagnetic installing
Set 3 and second calutron 4 the curved rising of electric current；The maximum speed of power output shaft 5 is 696.43 revs/min under this state
Clock；So the theoretical maximum speed of the electric vehicle is 55km/h.
Low-reverse control method is that manipulation direction of traffic control button guarantees that control circuit controls 3 He of the first calutron
Second calutron 4 makes vehicle be in state of rolling backward.After rotating running speed control handle, control circuit controls the first electromagnetic installing
Set 3 and second calutron 4 keep outer gear ring 2a opposite with the direction of rotation of sun gear 2c；First output shaft 3a in this control method
Direction of rotation and low speed move ahead control method in the first output shaft 3a direction of rotation it is opposite.The reversing most high speed of the electric vehicle
Degree is 12.7km/h, thus has the advantages that reversing safety.
In conclusion this two wheels electric vehicle has, climbing capacity is strong, shift is uniform, the acceleration time is short and most high speed is reasonable
Advantage, and this two wheels electric vehicle have the advantages that stroke mileage is long.
