Input power splits into two-way by the first input element 22 that increases square unit 2, one the road flows into output element 21, another road splits into two-way again through the input element 32 that linkage member 24 flows into next speed adjustment unit 3, one the road flows into output element 31, another road flows into second input element 22 that increases square unit 2 through linkage member 34, and repeats above-mentioned shunting process.
because the rotating speed relations of distribution of above-mentioned each element can change, two-way power stream will change according to the variation of rotating speed distribution between the two, when each output element 21 rotating speeds are zero, its output power is zero, but moment is non-vanishing, at this moment, the input power of each linkage member 24 changes to maximum value by certain value, described certain value refers to rotating speed when each linkage member 24 and separately output element 21 when identical, both press the value that the planet row torque ratio distributes the input power gained, described maximum value refers to the total output by input element 22 inputs that increase square unit 2 that coordinate separately, that is to say, when two-way power changes, each linkage member 24 will play bending moment, make its moment that is delivered to the input element 32 of next speed adjustment unit 3 separately after minute square, the moment that is delivered to again output element 31 separately also changes thereupon, thereby make through after each driving mechanism 4, the moment that is delivered to again on output shaft 7 also changes thereupon.
in addition, because the rotating speed relations of distribution of above-mentioned each element can change, so each increase the output element 21 of square unit 2 and speed adjustment unit 3 output element 31 rotating speed can from zero to the rotating speed same range as of separately input element 22 and input element 32 in constantly change, so they can transmit input power with different separately rotating speeds, thereby the output terminal 42 of the driving mechanism 4 of each different drive ratios can be connected simultaneously with output shaft 7, this is to increase the linkage member 24 of square unit 2 and the input element 32 of each speed adjustment unit 3 plays speed governing because of each, make the rotating speed of linkage member 34 of each speed adjustment unit 3 identical with the rotating speed of the input element 22 that increases square unit 2 that connects separately, namely the rotating speed with input shaft 1 is identical.
the input power of motor splits into two-way by the first input element 22 that increases square unit 2, one the road flows into output element 21, another road splits into two-way again through the input element 32 that linkage member 24 flows into first speed adjustment unit 3, one the road flows into output element 31, another road flows into second input element 22 that increases square unit 2 through linkage member 34, split into again two-way, one the road flows into output element 21, another road splits into two-way again through the input element 32 that linkage member 24 flows into second speed adjustment unit 3, one the road flows into output element 31, another road flows into joiner 6 through linkage member 34, flowed into the input end 61 of joiner 6 by the linkage member 34 of second speed adjustment unit 3 when input power, it is the input element 82 that joiner increases square unit 8, its input power splits into two-way, one the road flows into output element 81, another road splits into two-way again through the input element 92 that linkage member 84 flows into joiner speed adjustment unit 9, one the road flows into output element 91, another road flows into the present invention's some elements in addition through linkage member 94, wherein, flow into the power that joiner increases the output element 91 of the output element 81 of square unit 8 and joiner speed adjustment unit 9, through with overrunning clutch 5 that they coordinate separately after, flow into respectively again the joining shaft 10 that each overrunning clutch 5 connects separately, at last, the power that flows into joining shaft 10 all is delivered to input shaft 1 of the present invention, thereby realized converging with the power of motor, wherein, flow into the power of the output element 31 of each output element 21 that increases square unit 2 and speed adjustment unit 3, through with driving mechanism 4 that they coordinate separately after, be delivered to again output shaft 7 of the present invention, thereby realized the power of motor is externally exported by output shaft 7.
For the present invention, when the rotating speed of input shaft 1 constant, moment of torsion on output shaft 7 changes with the variation of its rotating speed, rotating speed is lower, moment of torsion on output shaft 7 is just larger, otherwise, less, thus but realize that the present invention can change with the difference of Vehicle Driving Cycle resistance the compound multi-gear simultaneous meshing variable speed unit of moment and speed.
when the present invention uses, if the input power of motor, input speed with and load constant, the rotating speed and the moment of torsion that are input shaft 1 are constant, before vehicle starting, the rotating speed of output shaft 7 is zero, work as automobile starting, because of output shaft 7 transfixions, be that each increases the output element 21 of square unit 2 and output element 31 transfixions of speed adjustment unit 3, each power that increases the input element 32 of the input element 22 of square unit 2 or speed adjustment unit 3 all flows into linkage member 24 or linkage member 34, make moment of torsion greater than the input torque of separately input element 22 after its bending moment, or make rotating speed greater than the input speed of separately input element 32 after its speed change, and be delivered to next speed adjustment unit 3 or increase square unit 2, they are again because identical reason, repeat above-mentioned situation, at this moment, the moment of torsion that each cooperatively interacts increases the output element 31 of the output element 21 of square unit 2 and speed adjustment unit 3 reaches maximum value, after the driving mechanism 4 that moment of torsion passes through with they coordinate separately, be delivered to output shaft 7, with the linkage member 34 of last speed adjustment unit 3, moment of torsion is delivered to joiner 6, 62 of the output terminals of joiner 6 are delivered to input shaft 1 to moment of torsion, realize converging with the input torque of motor, and increase between square unit 2 and speed adjustment unit 3 at each and constantly divide square, the iterative cycles of bending moment and remittance square, the moment of torsion of the output element 31 that is delivered to each output element 21 that increases square unit 2 or speed adjustment unit 3 is constantly increased, thereby the moment of torsion that is delivered to each driving mechanism 4 is constantly increased, and be delivered to output shaft 7, when the moment of torsion that is delivered on output shaft 7, when power train is transferred to the tractive force that produces on driving wheel and is enough to overcome the vehicle starting resistance, automobile starts to walk and begins to accelerate, the rotating speed that each that links with it increases the output element 31 of the output element 21 of square unit 2 and speed adjustment unit 3 also increases gradually from zero, at this moment, power is divided into two-way, the power that flows into the linkage member 34 of each linkage member 24 that increases square unit 2 and speed adjustment unit 3 reduces gradually, thereby, its the square effect that increases is reduced gradually, the moment of torsion of output shaft 7 reduces along with the increase of rotating speed, when each increases the rotating speed of the input element 32 of the input element 22 of square unit 2 and speed adjustment unit 3 and separately output element 21 and output element 31 when identical, linkage member 24 separately and linkage member 34 do not recur and increase square or chronotropic action.
