Below in conjunction with Figure of description and embodiment, the present invention is described in further detail:
Embodiment:
As shown in fig. 1, the gear-driven fluid coupling of a kind of combined harmonic, comprise input shaft 1, output shaft 3, output gear wheel set 4, gear 5, fluid coupling 6, input gear pair 7, overrunning clutch 8, the input end 81 of described overrunning clutch 8 connects with the fixed element beyond the present invention, three wave generators are provided with between described input shaft 1 and output shaft 3, three flexbile gears, just take turns for three, first wave generator 21 connects with input shaft 1, and with first flexbile gear 22 coordinated, first just wheel 23 connection, first just wheel 23 just taken turns connected with second, just take turns and second wave generator coordinated for second, second flexbile gear connects, second flexbile gear is just taken turns connect with the 3rd, just take turns and the 3rd wave generator coordinated for 3rd, 3rd flexbile gear connects, 3rd wave generator connects with second wave generator and output shaft 3, just take turns for 3rd and connected with the input gear 41 of the element beyond the present invention and output gear wheel set 4, the output gear 42 of output gear wheel set 4 connects with the input end 51 of gear 5, the output terminal 52 of gear 5 connects with the input end 61 of fluid coupling 6, the output terminal 62 of fluid coupling 6 and the output terminal 82 of overrunning clutch 8 connect with the input gear 71 of input gear pair 7, the output gear 72 of input gear pair 7 connects with first flexbile gear 22.
Described each needs to connect, and by the element of some other element separate, can adopt the method for hollow, through some other elements, connects with it.
Second is just taken turns the power dividing being delivered to this is two-way, one road flows into second wave generator, another road is through second flexbile gear, flow into the 3rd just wheel again, 3rd just wheel be two-way the power dividing being delivered to this again, one road flows into the 3rd wave generator, and another road flows into the 3rd flexbile gear.
Because the rotating speed relations of distribution of each element above-mentioned can change, change according to rotating speed distribution between the two changes by two-way poower flow, when second wave generator, when the rotating speed of the 3rd wave generator is zero, its output power is zero, but moment is non-vanishing, now, the input power of second wave generator and the 3rd wave generator then changes to maximum value by certain value, described certain value refers to when second wave generator, 3rd wave generator and second flexbile gear coordinated separately, when the rotating speed of the 3rd flexbile gear is identical, both press the value that planet row torque ratio distributes input power gained, described maximum value refers to just has taken turns by second, the total output of the 3rd just wheel input, that is, when two-way power changes, be delivered to second wave generator, moment on 3rd wave generator and output shaft 3 also changes thereupon.
The input power of motor is through input shaft 1, again through first wave generator 21, power transimission has just been taken turns 23 to first, be delivered to second just wheel again, and be two-way power dividing, one road flows into second wave generator, another road flows into second flexbile gear, flow into the 3rd just wheel again, 3rd just wheel be two-way power dividing again, one road flows into the 3rd wave generator, another road flows into the 3rd flexbile gear, 3rd flexbile gear splits into two-way again power, one road flows into the some element works done beyond the present invention, another road flows into the input gear 41 of output gear wheel set 4, the input gear 41 of output gear wheel set 4 is the output gear 42 of power transimission to output gear wheel set 4, the output gear 42 of output gear wheel set 4 is again the input end 51 of power transimission to gear 5, the input end 61 of fluid coupling 6 is flowed into again through its output terminal 52, the input gear 71 of input gear pair 7 is flowed into again through the output terminal 62 of fluid coupling 6, the output gear 72 of input gear pair 7 again power transimission to first flexbile gear 22, be delivered to first flexbile gear 22 this road power and by motor through input shaft 1, again through the power of first wave generator 21, then all be delivered to first just wheel 23, just take turns 23 for first and repeated said process again, make to be delivered to second wave generator, the power of the moment on the 3rd wave generator constantly increases, and be passed to output shaft 3 of the present invention, thus achieve the power of motor is externally exported by output shaft 3.
For the present invention, when the rotating speed of input shaft 1 is constant, moment of torsion on second wave generator, the 3rd wave generator and output shaft 3 changes with the change of its rotating speed, rotating speed is lower, the moment of torsion be delivered on first flexbile gear, 22, second wave generator, the 3rd wave generator and output shaft 3 is larger, otherwise, then less, thus realize the present invention can change moment and the speed gear-driven fluid coupling of combined harmonic with the difference of vehicle travel 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 3 is zero, work as automobile starting, the input power of motor is through input shaft 1, be delivered to first wave generator 21, wherein, first flexbile gear 22 is flowed into through input gear secondary 7 owing to now there is no power, and first flexbile gear 22 and overrunning clutch 8 output terminal 82 connect with the output gear 72 of input gear pair 7 and the input gear 71 of input gear pair 7 respectively, and the input end 81 of overrunning clutch 8 connects with the fixed element beyond the present invention, play restriction to turn to, what make that first flexbile gear 22 can not be contrary with motor turns to rotation, rotating speed is zero, now, be delivered to the power of first wave generator 21, then just take turns 23 by first power transimission has just been taken turns to second, and be two-way power dividing, one road flows into second wave generator, another road flows into second flexbile gear, flow into the 3rd just wheel again, 3rd just wheel be two-way power dividing again, one road flows into the 3rd wave generator, another road flows into the 3rd flexbile gear, 3rd flexbile gear splits into two-way again power, one road flows into the some element works done beyond the present invention, another road flows into the input gear 41 of output gear wheel set 4, the input gear 41 of output gear wheel set 4 is the output gear 42 of power transimission to output gear wheel set 4, the output gear 42 of output gear wheel set 4 is again the input end 51 of power transimission to gear 5, the input end 61 of fluid coupling 6 is flowed into again through its output terminal 52, the input gear 71 of input gear pair 7 is flowed into again through the output terminal 62 of fluid coupling 6, the output gear 72 of input gear pair 7 again power transimission to first flexbile gear 22, be delivered to first flexbile gear 22 this road power and by motor through input shaft 1, again through the power of first wave generator 21, then all be delivered to first just wheel 23, just take turns 23 for first and repeated said process again, constantly a point square is carried out between each element, the iterative cycles of bending moment and remittance square, make to be delivered to second wave generator, the power of the moment on the 3rd wave generator constantly increases, and be passed to output shaft 3 of the present invention, when being delivered to the moment of torsion on output shaft 3, 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, second wave generator be connected with it, the rotating speed of the 3rd wave generator and output shaft 3 also increases gradually from zero, now, the power flowing into first flexbile gear 22 reduces gradually, thus the moment of torsion of output shaft 3 is reduced along with the increase of rotating speed.
