Specific implementation mode
As shown in Figure 1, bi-motor twin shaft output speed changer of the present invention, a kind of bi-motor twin shaft output speed changer, feature
It is：
Including gearbox 7, the first driving motor mechanism 1 and the second driving motor mechanism 2 that are placed in outside the gearbox 7,
Further include the first input shaft 3 being placed in gearbox 7, the second input shaft 4 and the first output shaft 5, the second output shaft 6；
First output shaft 5 passes through the first input gear mechanism with the first input shaft 3 respectively of output gear mechanism 51
31,41 parallel coupling of the second input gear mechanism of the second input shaft 4；
First output shaft 5 is stretched out from 7 side of gearbox, as the first output end；Second output shaft 6 is along the first output
The opposite direction of 5 axis of axis is stretched out from 7 other side of gearbox, as second output terminal；
Second output shaft 6 is fixedly connected with the first output shaft 5 in gearbox 7；
One end of first input shaft 3 is stretched out from 7 side of gearbox, is engaged with the first driving motor mechanism 1；
One end of second input shaft 4 is stretched out from 7 side of gearbox, is engaged with the second driving motor mechanism 2.
The present invention is engaged by the first input shaft 3 with the first driving motor mechanism 1, the second input shaft 4 and second driving electricity
Machine mechanism 2 engages, and realizes the input of bi-motor twin shaft, realizes that " zero " speed discrepancy hangs shelves, " zero " torque plucks shelves, you can to realize without dynamic
Power interrupts gear shift.
First output shaft 5 and the second output shaft 6 of the invention are stretched out from 7 both sides of gearbox respectively, are respectively used as an output end, i.e.,
Both ends export, and heavy vehicle high-power driving and the demand of steering may be implemented.
Second output shaft 6 can be two individual axis being fixedly connected in gearbox 7 with the first output shaft 5, also may be used
To be an entirety.
By be arranged dual input motor, can also by the first driving motor mechanism 1, the second driving motor mechanism 2 it is flexible
It is arranged and matches, realizes the recycling of braking energy.The permanent torque or perseverance of motor more can be further realized in Brake energy recovery
Current control.
According to technology arrangement requirement and power demand, the first driving motor mechanism 1 and the second driving motor mechanism 2 can positions
In the different side of gearbox 7.But preferably, first driving motor mechanism 1 and the second driving motor mechanism 2 are located at speed change
The homonymy of case 7.To be more advantageous to arrangement and maintenance.
It is used cooperatively scene to be more advantageous to, it is preferable that the gear mechanism 51, the first input gear mechanism 31, second
Input gear mechanism 41 is respectively three；
Described three the first input gear mechanisms 31 correspond to I, III, V grade respectively, three second input gear mechanisms
41 correspond to II, IV, VI grade respectively.
It will be understood by those in the art that according to different stalls demand, gear mechanism 51, the first input gear mechanism 31,
The number of two input gear mechanisms 41 can increase and decrease.
First input shaft 3 is located at the side of output shaft 5 as a preferred method, and the second input shaft 4 is located at defeated
The other side of shaft 5.
On the one hand such arrangement makes input shaft 3,4 be located at 5 both sides of output shaft, output shaft 5 is more easy to reach dynamic equilibrium,
On the other hand arrangement and the maintenance of the equipment being located at outside gearbox 7 being connected with them are also allowed for.
To realize that the smooth transition of driving motor and transmission input shaft connects, as a preferred method, described first
Driving motor mechanism 1 includes the first driving motor 11 and the first retarder 12, the input terminal and first of first retarder 12
The output shaft of driving motor 11 is fixedly connected, and the output end of the first retarder 12 is engaged with one end of the first input shaft 3.
Similarly, second driving motor mechanism 2 includes the second driving motor 21 and the second retarder 22, and described second subtracts
The input terminal of fast device 22 is fixedly connected with the output shaft of the second driving motor 21, the output end of the second retarder 22 and the second input
It engages one end of axis 4.
The first input shaft 3 being connect with the first driving motor mechanism 1 waits odd numbers shelves equipped with I, III, V ...；It is driven with second
The second input shaft 4 that dynamic motor mechanism 2 connects, even gears are waited equipped with II, IV, VI ....Arbitrary single shelves can be by matching phase
The driving motor mechanism of respective shaft realizes power transmission；Arbitrary odd number shelves and arbitrary even gear are simultaneously operable, i.e., the first driving
Motor mechanism 1 and the second driving motor mechanism 2 can be carried out at the same time power input.Any two of which odd number or even gear cannot be same
When work.
It such as wants two motors all to work in high efficient district, and can realize continual output torque and output rotation speed change, it can
Using following shift strategy.
Ⅰ→Ⅰ+Ⅱ→Ⅱ→Ⅱ+Ⅲ→Ⅲ……→
When single motor works, another motor shaft can realize " zero " speed discrepancy gear shift by electric machine speed regulation.When two electricity
When machine works at the same time, by the output matching of two motors, it can be achieved that " zero " torque plucks shelves, gear shift.
When automobile brake, it is technological means commonly used in the art that extra energy regenerating, which is used for generating electricity, but due to electricity
The voltage and current of machine device power generation output is fluctuation, cannot efficiently be recycled.But the dual-motor variable speed of the application
Because there are two driving motors, when power generation, by bi-motor from main regulation, constant current or permanent electricity may be implemented in device
The power generation of pressure, that is to say, that can effectively realize that battery charges.
A kind of bi-motor twin shaft output speed changer that the present invention describes, can be met with bidirectional output heavy vehicle it is high-power and
The requirements such as steering；Power failure-free gear shift may be implemented, realize that shelves or gear shift are plucked in " zero " speed discrepancy gear shift, " zero " torque,
And improve the efficiency of motor；The power generation of constant current or constant voltage may be implemented in gear arrangement provided by the invention.
