Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Embodiment:
As shown in fig. 1, a kind of torque-converters, it comprises input shaft 1, joiner 3, output shaft 4, be provided with between input shaft 1 and output shaft 4 and input gear ring 21, output gear 22, planetary pinion 23, public output planetary frame 24, conjugation tooth ring 25, gearwheel 26, common carrier 27, connect gear 28, small gear 29, input gear ring 21 connects with input shaft 1, and by planetary pinion 23 and public output planetary frame 24, conjugation tooth ring 25 connects, conjugation tooth ring 25 is by planetary pinion 23 and output gear 22, public output planetary frame 24 connects, output gear 22 connects with gearwheel 26, gearwheel 26 is by planetary pinion 23 and common carrier 27, connect gear 28 to connect, connect gear 28 by planetary pinion 23 and common carrier 27, small gear 29 connects, small gear 29 connects with the some elements beyond the present invention, common carrier 27 is connected with input gear ring 21 by joiner 3, 24, public output planetary frame connects with output shaft 4.
Overrunning clutch selected by described joiner 3.
Input gear ring 21 is divided into two-way by the planetary pinion 23 on public output planetary frame 24 input power, the public output planetary frame 24 of a kind of inflow, one group of planetary pinion 23 of separately leading up on public output planetary frame 24 flows into conjugation tooth ring 25, distribute two-way again, one road flows into public output planetary frame 24, and another group planetary pinion 23 of separately leading up on public output planetary frame 24 flows into output gear 22.
Because the rotating speed relations of distribution between each element above-mentioned can change, change according to rotating speed distribution between the two changes by two-way poower flow, when public output planetary frame 24 rotating speed is zero, its output power is zero, but moment is non-vanishing, now, the input power of conjugation tooth ring 25 then changes to maximum value by certain value, described certain value refers to when conjugation tooth ring 25 is identical with the rotating speed of public output planetary frame 24, both press the value that planet row torque ratio distributes input power gained, described maximum value refers to the total output inputted by motor, that is, when two-way power changes, conjugation tooth ring 25 will play bending moment effect, the moment that its being delivered to is total on output planetary frame 24 and output shaft 4 also changes thereupon.
The input power of motor splits into two-way through input gear ring 21, one road flows into public output planetary and returns 24, another road flows into conjugation tooth ring 25, this power splits into two-way again, one road flows into public output planetary frame 24, another road flows into gearwheel 26 through output gear 22, gearwheel 26 splits into two-way again, one tunnel inflowization concurrence carrier 27, another road flows into attachment tooth and does 28, this power splits into two-way again, one road flows into public planet and returns 27, another road flows into the some element works done beyond the present invention through small gear 29, wherein, the power on this road of common carrier 27 flows into input gear ring 21 by joiner 3, conflux with the input power of motor, and repeat above-mentioned branching process, the power on public this road of output planetary frame 24 is then delivered to output shaft 4, thus achieve the power of motor is externally exported by output shaft 4.
For the present invention, when the rotating speed of input shaft 1 is constant, the moment of torsion on output shaft 4 changes with the change of its rotating speed, rotating speed is lower, and the input torque of output shaft 4 is larger, otherwise, then less, thus realize the present invention can change moment torque-converters with the difference of Vehicle Speed and resistance.
When the present invention uses, if the input power of motor, input speed and load constant, namely the rotating speed of input shaft 1 and moment of torsion are constant, before vehicle starting, the rotating speed of output shaft 4 is zero, work as automobile starting, because of output shaft 4 transfixion, namely common output planetary frame 24 transfixion is divided, the power of motor all flows into conjugation tooth ring 25, moment of torsion is made to be greater than the input torque of motor after its bending moment, and be divided into two-way, one tunnel is delivered to public output planetary frame 24, another road flows into conjugation tooth ring 25, this power splits into two-way again, one road flows into public output planetary frame 24, another road flows into gearwheel 26 through output gear 22, gearwheel 26 splits into two-way again, one road flows into common carrier 27, another road flows into and connects gear 28, this power splits into two-way again, one road flows into common carrier 27, another road flows into and connects gear 28, this power splits into two-way again, one road flows into common carrier 27, another road flows into the some element works done beyond the present invention through small gear 29, wherein, the power transimission on public this road of output planetary frame 24 is to output shaft 4, the power on this road of common carrier 27 then flows into input gear ring 21 by joiner 3, realize converging with the input torque of motor, and repeat above-mentioned branching process, constantly a point square is carried out between each element, the iterative cycles of bending moment and remittance square, the moment of torsion of the public output planetary frame 24 of transmission is constantly increased, and be delivered to output shaft 4, when being delivered to the moment of torsion on output shaft 4, through power train be transferred to the tractive force that driving wheel produces be enough to overcome vehicle starting resistance time, automobile is then started to walk and is started to accelerate, the rotating speed of the public output planetary frame 24 be connected with it also increases gradually from zero, now, power is divided into two-way, flow into the power connecting internal messing gear ring 25 to reduce gradually, thus its increasing square effect is reduced gradually, the moment of torsion of output shaft 4 reduces along with the increase of rotating speed, when input shaft 4 is identical with the rotating speed of input gear ring 21, conjugation tooth ring 25 does not recur and increases square effect.
