Among above-mentioned all embodiments; Orderings that several of work of cooperatively interacting increase square unit 2 and raising speed unit 3 can change; After the change; To them generally speaking, increase square unit 2 to first exactly or raising speed unit 3 is replaced as last unit, the output element 32 of 31 of its input element 21 or input elements and original last raising speed unit 3 or the output element 22 that increases square unit 2 connect; 32 of its output element 22 or output elements connect with the input end 41 of joiner 4; 33 of its public output element 23 or public output elements connect the back successively or are identity element with the public output element 33 and the public output element 23 of several unit, and promptly shared public output element 123 connects with the output terminal 42 of joiner 4 again; The output terminal 42 of joiner 4 connects with output shaft 5; When joiner 4 was overrunning clutch, the input element 31 of 42 of the output terminals of joiner 4 and original last raising speed unit 3 or the input element 21 that increases square unit 2 connected, the public output element 33 of 33 of its public output element 23 or public output elements and several unit and public output element 23 connects afterwards successively or be identity element; It is shared public output element 123; Connect with output shaft 5 again, and original second raising speed unit 3 or increase square unit 2 just input element 31 or input element 21 change into input shaft 1 and connect, object of each element connection of two elements and all the other each unit is constant in addition for it.
For the present invention, when the rotating speed of input shaft 1 is constant, the moment of torsion on the output shaft 5 changes with its change in rotational speed; Rotating speed is low more, and the moment of torsion of output shaft 5 is big more, otherwise; Then more little, thus realize that the present invention can be with the different torque-converters that change moment of torsion of Vehicle Speed and resistance.
When the present invention used, input power, input speed and the load thereof of establishing motor were constant, and promptly the rotating speed of input shaft 1 and moment of torsion are constant; Before the vehicle starting, the rotating speed of output shaft 5 is zero, works as automobile starting; Because of output shaft 5 transfixions, the power of motor all flows into the first output element 22 of square unit 2 or the output element 32 of raising speed unit 3 of increasing, and makes moment of torsion behind its bending moment greater than the input torque of motor or the rotating speed after the speed change input speed greater than motor; And be delivered to the next one and increase square unit 2 or raising speed unit 3; This element all flows into power the output element 22 or the output element 32 of this unit again again because of identical reason, makes its moment of torsion increase or the rotating speed of its output is realized with the identical or above-mentioned two kinds of situation of the rotating speed of input shaft 1 simultaneously; And all flow into the next one to power and increase the output element 22 of square unit 2 or the output element 32 of raising speed unit 3; And repeat above-mentioned situation, through several increase square unit 2 or and raising speed unit 3 after, the output element 22 of last unit or output element 32 pass to moment of torsion the input end 41 of joiner 4; Again through the output terminal of joiner 4 42 with by the public output element 23 of each unit or and after the moment of torsion of public output element 33 or shared public output element 123 one tunnel converges; Be delivered to output shaft 5 to moment of torsion again, at this moment, moment of torsion reaches maximum value; When if joiner 4 is overrunning clutch, 42 of its output terminals pass to input element 21 or input element 31 with another unit of last unit matching work to moment of torsion, and after converging with the input torque of this element; Then in the end one increase the circulation repeatedly of constantly carrying out branch square, bending moment between square unit 2 and the raising speed unit 3 and converging square; The moment of torsion that is delivered to shared public output element 123 is constantly increased, and pass to output shaft 5, when the moment of torsion of output shaft 5; When power train is transferred to the tractive force that produces on the driving wheel and is enough to overcome the vehicle starting resistance; Automobile then starts to walk and begins to quicken, all the public output elements 23 on the shared public output element 123 that links with it or and the rotating speed of public output element 33 also increase gradually from zero, at this moment; Power is divided into two-way; Flow into each output element that increases square unit 2 22 or and the power of the output element 32 of raising speed unit 3 reduce gradually, thereby, the square effect that increases of each output element that increases square unit 2 22 is reduced gradually; The moment of torsion of output shaft 5 reduces along with the increase of rotating speed; When public output element 23 or and the rotating speed of the rotating speed of public output element 33 or shared public output element 123 and input shaft 1 when identical, the output element 22 of each unit or and output element 32 and separately input element 21 or and the rotating speed of input element 31 identical, promptly speed discrepancy is zero; At this moment, each output element 22 that increases square unit 2 does not recur and increases the square effect.
