Go out bull gear 22, another road is delivered to input gear ring 26 through the little gear ring 23 of output, and input gear ring 26 passes through output planetary again
20 power dividings for being delivered to this of planetary gear on frame 24 are two-way, and a road flows into output planetary frame 24, and another road flows into
Output gear 25.
As the rotating speed relations of distribution of each element above-mentioned can change, two-way power flow will be according to rotating speed between the two
The change of distribution and change, when exporting bull gear 22, when the rotating speed of output planetary frame 24 is zero, power output is zero, but torque
Be not zero, now, the input power of bull gear 22, output planetary frame 24 is exported then by certain value change to maximum, described
Certain value is referred to work as output bull gear 22, output planetary frame 24 and the respective input planet carrier 21 for coordinating, is input into gear ring 26
When rotating speed is identical, both press the value that planet row torque ratio distributes input power gained, and described maximum is referred to by line of input
The general power that carrier 21, input gear ring 26 are input into, that is to say, that when two-way power changes, be delivered to output bull gear
22nd, the torque on output planetary frame 24 also changes therewith.
Input gear 121 or engine of the input power of starter by starter toothed wheel 14 through starting input gear pair 12
Input power is through input shaft 1, then is delivered to the output gear 122 for starting input gear pair 12 by freewheel clutch 13, and leads to
The planetary gear 20 that crosses on input duplex planet frame 9 is delivered to power the input gear 141 of output gear wheel set 4, then through output
The output gear 142 of gear pair 4 is delivered to input planet carrier 21, is input into planet carrier 21 by planetary gear 20 thereon transmission
It is two-way to this power dividing, a road flows into output bull gear 22, another road is delivered to input tooth through the little gear ring 23 of output
Circle 26, it is two-way that input gear ring 26 passes through 20 power dividings for being delivered to this of planetary gear on output planetary frame 24 again,
One road flows into output planetary frame 24, and another road flows into the input gear 71 of output gear wheel set 7, output gear wheel set through output gear 25
7 output gear 72 is two-way power dividing again, and a road flows into gear 6, then the input gear through input gear pair 10

For two-way, road inflow output bull gear 22, another road are delivered to input gear ring 26, input gear ring through the little gear ring 23 of output
26 is two-way by 20 power dividings for being delivered to this of planetary gear on output planetary frame 24 again, and a road flows into output row
Carrier 24, another road flow into the input gear 71 of output gear wheel set 7, the output gear 72 of output gear wheel set 7 through output gear 25
It is two-way power dividing again, a road flows into gear 6, then the input gear 101 through input gear pair 10 flows into input tooth
The output gear 102 of wheel set 10, then power is delivered to input duplex planet frame 9, another road flows into rearmounted gear housing formula liquid
The input 151 of couple clutch 15, the output end 152 of rearmounted gear housing formula fluid-flywheel clutch 15 is again through starting input gear
Secondary 12 input gear 121, flows into the output gear 122 for starting input gear pair 12, is delivered to and starts input gear pair 12
This road power of output gear 122, then and by starter or engine be delivered to the output gear 122 for starting input gear pair 12
Power converge, and with flow into the power of input duplex planet frame 9, all pass through the planetary gear on input duplex planet frame 9
20 input gears 41 for being delivered to output gear wheel set 4, the input gear 41 of output gear wheel set 4 repeat said process, make transmission
Torque on output bull gear 22, output planetary frame 24 constantly increases, and is delivered to the work(of connection gear 8 through exporting bull gear 22
Rate and the power being delivered on output planetary frame 24, all pass through the input 161 of empty gear mechanism 16, one-way clutch 11 with
And input shaft 1 is delivered on engine crankshaft, when the starting power of generation be enough to the starting reactance for overcoming engine, engine then rises
Move and start to accelerate.
After engine is started, if the input power of engine, input speed and its load are constant, i.e. the rotating speed of input shaft 1
It is constant with moment of torsion, before vehicle starting, the empty gear mechanism 16 of engagement, the rotating speed of output shaft 3 is zero, the input power warp of engine
Input shaft 1 and freewheel clutch 13, are delivered to the output gear 122 for starting input gear pair 12, wherein, due to now not having
There is power that input duplex planet frame 9 is flowed into, and the input 51 of fixing one-way clutch 5 is coupled with retaining element, is risen and is limited
The effect of steering, rotates the steering that input duplex planet frame 9 can not be contrary with engine, and rotating speed is zero, now, has been delivered to
The power of the output gear 122 of dynamic input gear pair 12, then passed power by the planetary gear 20 on input duplex planet frame 9
The input gear 41 of output gear wheel set 4 is delivered to, then the output gear 42 through output gear wheel set 4 is delivered to input planet carrier 21, defeated
It is two-way to enter planet carrier 21 by 20 power dividings for being delivered to this of planetary gear thereon, and a road flows into output bull gear
22, another road is delivered to input gear ring 26 through the little gear ring 23 of output, and input gear ring 26 is again by output planetary frame 24
20 power dividings for being delivered to this of planetary gear are two-way, and a road flows into output planetary frame 24, and another road is through output gear 25
Flow into the input gear 71 of output gear wheel set 7, the output gear 72 of output gear wheel set 7 is two-way power dividing again, and a road is flowed
Enter gear 6, then the input gear 101 through input gear pair 10 flows into the output gear 102 of input gear pair 10, then work(
Rate is delivered to input duplex planet frame 9, and another road flows into the input 151 of rearmounted gear housing formula fluid-flywheel clutch 15, rearmounted
Input gear 121 of the output end 152 of gear housing formula fluid-flywheel clutch 15 again through starting input gear pair 12, flows into starting defeated
Enter the output gear 122 of gear pair 12, be delivered to this road power for the output gear 122 for starting input gear pair 12, then and by
Starter or engine are delivered to the power of the output gear 122 for starting input gear pair 12 and converge, and double with input is flowed into
The power of connection planet carrier 9, all passes through the input tooth that the planetary gear 20 on input duplex planet frame 9 is delivered to output gear wheel set 4
Wheel 41, the input gear 41 of output gear wheel set 4 repeats said process, makes to be delivered to output bull gear 22, output planetary frame 24
On torque constantly increase, be delivered to the connection power of gear 8 and be delivered on output planetary frame 24 through exporting bull gear 22
Power, then be transferred to the output shaft 3 of the present invention by empty gear mechanism 16, when the moment of torsion being delivered on output shaft 3, through passing
When the tractive force that dynamic drive system is produced on driving wheel be enough to overcome vehicle starting resistance, automobile is then started to walk and starts to accelerate,
Associated output bull gear 22, the rotating speed of output planetary frame 24 are also gradually increased from zero, now, flow into input duplex planet
The power of frame 9 is gradually decreased, so that the moment of torsion of output shaft 3 is reduced with the increase of rotating speed.
