Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:
Embodiment:
A kind of composite multi-disk type stepless variable speed unit, comprise input shaft 1, multi-disk type stepless variable speed unit 3, gear pair 4, output shaft 5, the output gear 42 of described each gear pair 4 connects with output shaft 5, be provided with input flexbile gear 21 between described input shaft 1 and the output shaft 5, output wave mode generator 22, connect wheel 23 just, connect flexbile gear 24, output flexbile gear 25, input flexbile gear 21 connects with input shaft 1, and with first output wave mode generator 22, first connects just, and wheel 23 connects, first connects just wheel 23 and first output wave mode generator 22, connecting flexbile gear 24 connects, connect flexbile gear 24 and second output wave mode generator 22, second connects wheel 23 connections just, second connects the wave mode of 23 and second output of wheel just generator 22, output flexbile gear 25 connects, output flexbile gear 25 connects with the input end 31 of multi-disk type stepless variable speed unit 3, and the output terminal 32 of multi-disk type stepless variable speed unit 3 and first output wave mode generator 22 and second output wave mode generator 22 connect with the input gear 41 of the gear pair 4 that cooperates separately respectively.
Input power splits into two-way by input flexbile gear 21, one the road flows into first output wave mode generator 22, another road connects just through first, and wheel 23 splits into two-way again, one the road flows into first output wave mode generator 22, and another road flows into and connects flexbile gear 24, connects flexbile gear 24 and splits into two-way again, one the road flows into second output wave mode generator 22, another road connects firm wheel 23 through second and splits into two-way again, and one the road flows into second output wave mode generator 22, and another road flows into exports flexbile gear 25.
Because the rotating speed relations of distribution of above-mentioned each element can change, so the rotating speed of each output wave mode generator 22 can constantly change in the scope identical with the rotating speed of input flexbile gear 21 from zero, thereby the gear pair 4 of each different drive ratios can be connected with output shaft 5 simultaneously, and this is that wheel 23 plays speed governing because of each connects just.
Because the rotating speed relations of distribution of above-mentioned each element can change, the two-way power circuit will change according to the variation of rotating speed distribution between the two, when each output wave mode generator 22 rotating speeds are zero, its output power is zero, but moment is non-vanishing, at this moment, each connects just, and the input power of wheel 23 then changes to maximum value by certain value, described certain value refers to when each and connects the rotating speed of just wheel 23 and the output wave mode generator 22 of cooperation separately when identical, both press the value that the harmonic gear drive mechanism torque ratio distributes the input power gained, described maximum value refers to by the input flexbile gear 21 that connects separately or connects the total output that flexbile gear 24 is imported, that is to say, when two-way power changes, each connects firm wheel 23 will play bending moment, and its moment that is delivered on each output wave mode generator 22 and the output shaft 5 is also changed thereupon.
The input power of motor splits into two-way through input flexbile gear 21, one the road flows into first output wave mode generator 22, another road connects just through first, and wheel 23 splits into two-way again, one the road flows into first output wave mode generator 22, another road flows into and connects flexbile gear 24, connect flexbile gear 24 and split into two-way again, one the road flows into second output wave mode generator 22, another road connects just through second, and wheel 23 splits into two-way again, one the road flows into second output wave mode generator 22, another road flows into output flexbile gear 25, output flexbile gear 25 flows into the input end 31 of multi-disk type stepless variable speed unit 3 again, again through the output terminal 32 of multi-disk type stepless variable speed unit 3, it is delivered to the input gear 41 of the gear pair 4 of cooperation separately to the power that flows into respectively again with first output wave mode generator 22 and second output wave mode generator 22, output gear 42 through each gear pair 4 confluxes to output shaft 5 of the present invention again, thereby has realized the power of motor is externally exported by output shaft 5.。
For the present invention, when the rotating speed of input shaft 1 constant, moment of torsion on the output shaft 5 changes with its change in rotational speed, rotating speed is low more, moment of torsion on the output shaft 5 is just big more, otherwise, then more little, thus realize that the present invention can change the composite multi-disk type stepless variable speed unit of moment and speed with the difference of vehicle driving resistance.
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 the vehicle starting, the rotating speed of output shaft 5 is zero, work as automobile starting, because of output shaft 5 transfixions, be each output wave mode generator 22 transfixions, the power of input flexbile gear 21 or connection flexbile gear 24 all flows into each and connects wheel 23 just, moment of torsion is increased, and be divided into two-way, one the tunnel is delivered to connection flexbile gear 24 or the output flexbile gear 25 that cooperates separately, another road is delivered to the output wave mode generator 22 that cooperates separately, wherein, output flexbile gear 25 flow into power the input end 31 of multi-disk type stepless variable speed unit 3, again through the output terminal 32 of multi-disk type stepless variable speed unit 3, it is delivered to the input gear 41 of the gear pair 4 of cooperation separately to the power that flows into respectively again with first output wave mode generator 22 and second output wave mode generator 22, output gear 42 through each gear pair 4 confluxes to output shaft 5 again, when the moment of torsion that is delivered on the 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, the rotating speed of each output wave mode generator 22 that links with it also increases gradually from zero, at this moment, power is divided into two-way, flowing into each power that connects firm wheel 23 reduces gradually, thereby, its the square effect that increases is reduced gradually, the moment of torsion of output shaft 5 reduces along with the increase of rotating speed, when relevant output wave mode generator 22 was identical with the rotating speed of importing flexbile gear 21, the firm wheel 23 of each connection did not recur and increases the square effect.
