Description of drawings
Fig. 1 is the structural drawing of the embodiment of the invention;
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment:
Embodiment:
As shown in fig. 1, a kind of composite pyramid type stepless variable speed unit, comprise input shaft 1, pyramid 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 planet carrier 21 between described input shaft 1 and the output shaft 5, planetary pinion 22, output gear 23, input gear 24, connect planet carrier 25, output planetary frame 26, output pinion 27, input planet carrier 21 connects with input shaft 1, and by one group of planetary pinion 22 on it and first output gear 23 that cooperates, first output pinion 27 connects, first output gear 23 connects with first input gear 24, connect planet carrier 25 by two groups of planetary pinions 22 on it with cooperate first import gear 24, first output pinion 27 and second output pinion 27, second output gear 23 connects, second output gear 23 connects with second input gear 24, output planetary frame 26 is imported gear 24 by one group of planetary pinion 23 on it with second that cooperates, second output pinion 27 connects, output planetary frame 26 connects with the input end 31 of pyramid type stepless variable speed unit 3, and the output terminal 32 of pyramid type stepless variable speed unit 3 and each output pinion 27 connect with the input gear 41 of the gear pair 4 that cooperates separately respectively.
Input power splits into two-way by input planet carrier 21, one the road flows into first output pinion 27, another road flows into first output gear 23, flow into first input gear 24 again, split into three the tunnel again through connecting planet carrier 25, the first via flows into first output pinion 27, the second the road flows into second output pinion 27, Third Road flows into second output gear 23, second output gear 23 flows into second input gear 24 again, and split into two-way, and one the road flows into second output pinion 27, and another road flows into output planetary frame 26.
Because the rotating speed relations of distribution of above-mentioned each element can change, so the rotating speed of each output pinion 27 can constantly change in the scope identical with the rotating speed of input planet carrier 21 from zero, thereby the gear pair 4 of each different drive ratios can be connected simultaneously with output shaft 5, because of each output gear 23 plays speed governing, make the rotating speed of input planet carrier 21, connection planet carrier 25, output planetary frame 26 identical.
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 pinion 27 rotating speeds are zero, its output power is zero, but moment is non-vanishing, at this moment, the input power of each output gear 23 then changes to maximum value by certain value, described certain value refers to rotating speed when each output gear 23 and the output pinion 27 that cooperates separately when identical, both press the value that planet row torque ratio distributes the input power gained, described maximum value refers to by the input planet carrier 21 that connects separately or connects the total output that planet carrier 25 is imported, that is to say, when two-way power changes, each output gear 23 will play bending moment, and its moment that is delivered on each output pinion 27 and the output shaft 5 is also changed thereupon.
The input power of motor splits into two-way through input planet carrier 21, one the road flows into first output pinion 27, another road flows into first output gear 23, flow into first input gear 24 again, split into three the tunnel again through connecting planet carrier 25, the first via flows into first output pinion 27, the second the road flows into second output pinion 27, Third Road flows into second output gear 23, second output gear 23 flows into second input gear 24 again, and split into two-way, one the road flows into second output pinion 27, another road flows into output planetary frame 26, output planetary frame 26 flows into the input end 31 of pyramid type stepless variable speed unit 3 again, again through the output terminal 32 of pyramid 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 pinion 27 and second output pinion 27, 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 pyramid 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 pinion 27 transfixions, the power of input planet carrier 21 or connection planet carrier 25 all flows into the output gears 23 that cooperate separately, moment of torsion is increased, and be divided into two-way, one the tunnel is delivered to the input gear 24 that cooperates separately, another road is delivered to the output pinion 27 that cooperates separately, wherein, output planetary frame 26 flows into power the input end 31 of pyramid type stepless variable speed unit 3, its output terminal 32 of flowing through again, and respectively the power that flows into is delivered to again the input gear 41 of the gear pair 4 that cooperates separately with first output pinion 27 and second output pinion 27, 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 pinion 27 that links with it also increases gradually from zero, at this moment, power is divided into two-way, and the power that flows into each output gear 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, and when relevant output pinion 27 was identical with the rotating speed of importing planet carrier 21, each output gear 23 did not recur and increases the square effect.
