Description of drawings
Fig. 1 is the structural drawing of the embodiment of the present 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 comprises 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, is provided with input planet carrier 21 between described input shaft 1 and 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 passes through one group of planetary pinion 22 and first output gear 23 that coordinates on it, first output pinion 27 connects, and first output gear 23 connects with first input gear 24, and connection planet carrier 25 passes through the two groups of planetary pinions 22 and first input gear 24 that coordinates on it, first output pinion 27 and second output pinion 27, second output gear 23 connects, and second output gear 23 connects with second input gear 24, and output planetary frame 26 passes through the one group of planetary pinion 23 and second input gear 24 that coordinates on it, second output pinion 27 connects, and 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 coordinates 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 again first input gear 24, 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 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, two-way power stream 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 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 coordinates separately when identical, both press the value that the 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 inputted, that is to say, when two-way power changes, each output gear 23 will play bending moment, its moment that is delivered on each output pinion 27 and 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 again first input gear 24, 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 power that flows into respectively the input gear 41 of the gear pair 4 that coordinates separately 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 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 output shaft 5 changes with the variation of its rotating speed, rotating speed is lower, moment of torsion on output shaft 5 is just larger, otherwise, less, thus realize that the present invention can change with the difference of Vehicle Driving Cycle resistance the composite pyramid type stepless 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 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 coordinate separately, moment of torsion is increased, and be divided into two-way, one the tunnel is delivered to the input gear 24 that coordinates separately, another road is delivered to the output pinion 27 that coordinates 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 coordinates 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 output shaft 5, 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 of each output pinion 27 that links with it also increases gradually from zero, at this moment, power is divided into two-way, 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, when relevant output pinion 27 is identical with the rotating speed of inputting planet carrier 21, each output gear 23 does not recur and increases the square effect.
