Embodiment:
As shown in fig. 1, a kind of composite steel ring separating cone type stepless variable speed unit, comprise input shaft 1, steel ring separating cone 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 gearwheel 21 between described input shaft 1 and the output shaft 5, planetary pinion 22, output pinion 23, output gearwheel 24, connect planet carrier 25, first input gearwheel 21 connects with input shaft 1, first connect planet carrier 25 by two groups of planetary pinions 22 on it with cooperate first input gearwheel 21, first output pinion 23 and second output pinion 23, first output gearwheel 24 connects, first output pinion 23 connects with second output pinion 23, first output gearwheel 24 connects with second input gearwheel 21, second connects planet carrier 25 by two groups of planetary pinions 22 on it and second the input gearwheel 21 that cooperates, the 3rd output pinion 23 and the 4th output pinion 23, second output gearwheel 24 connects, the 3rd output pinion 23 connects with the 4th output pinion 23, second output gearwheel 24 connects with the input end 31 of steel ring separating cone type stepless variable speed unit 3, the output terminal 32 of steel ring separating cone type stepless variable speed unit 3 and first, second output pinion 23 and the 3rd, the 4th output pinion 23 connects with the input gear 41 of the gear pair 4 that cooperates separately respectively.
Input power splits into two-way by first input gearwheel 21, one the road flows into first output pinion 23, another road connects planet carrier 25 through first and splits into two-way again, one the road flows into second output pinion 23, another road flows into first output gearwheel 24, flow into again second input gearwheel 21, second input gearwheel 21 splits into two-way again, one the road flows into the 3rd output pinion 23, another road connects planet carrier 25 through second and splits into two-way again, one the road flows into the 4th output pinion 23, and another road flows into second output gearwheel 24.
Because the rotating speed relations of distribution of above-mentioned each element can change, so the rotating speed of each output pinion 23 can constantly change in the scope identical with the rotating speed of each input gearwheel 21 from zero, thereby the gear pair 4 of each different drive ratios can be connected simultaneously with output shaft 5, play speed governing because each connects planet carrier 25, make the rotating speed of each input gearwheel 21 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 23 rotating speeds are zero, its output power is zero, but moment is non-vanishing, at this moment, each input power that connects planet carrier 25 then changes to maximum value by certain value, described certain value refers to when each and connects the rotating speed of planet carrier 25 and the output pinion 23 of cooperation separately when identical, both press the value that the planet row torque ratio distributes the input power gained, described maximum value refers to the total output by input gearwheel 21 inputs that connect separately, that is to say, when two-way power changes, each connects planet carrier 25 will play bending moment, and its moment that is delivered on each output pinion 23 and the output shaft 5 is also changed thereupon.
The input power of motor splits into two-way through first input gearwheel 21, one the road flows into first output pinion 23, another road connects planet carrier 25 through first and splits into two-way again, one the road flows into second output pinion 23, another road flows into first output gearwheel 24, flow into again second input gearwheel 21, second input gearwheel 21 splits into two-way again, one the road flows into the 3rd output pinion 23, another road connects planet carrier 25 through second and splits into two-way again, one the road flows into the 4th output pinion 23, another road flows into second output gearwheel 24, second output gearwheel 24 flows into the input end 31 of steel ring separating cone type stepless variable speed unit 3 again, again through the output terminal 32 of steel ring separating cone type stepless variable speed unit 3, itself and first, second output pinion 23 and the 3rd, the 4th output pinion 23 is delivered to the power that flows into respectively the input gear 41 of the gear pair 4 that cooperates separately again, 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 the variation of its rotating speed, rotating speed is lower, moment of torsion on the output shaft 5 is just larger, otherwise, then less, thus realize that the present invention can change with the difference of Vehicle Driving Cycle resistance the composite steel ring separating cone 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 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 23 transfixions, the power of each input gearwheel 21 all flows into the connection planet carrier 25 that cooperates separately, each increases moment of torsion after connecting planet carrier 25 bending moments, and be divided into two-way, one the tunnel is delivered to the output gearwheel 24 that cooperates separately, another road is delivered to the output pinion 23 that cooperates separately, wherein, second output gearwheel 24 flows into power the input end 31 of steel ring separating cone type stepless variable speed unit 3, again through the output terminal 32 of steel ring separating cone type stepless variable speed unit 3, itself and first, second output pinion 23 and the 3rd, the 4th output pinion 23 is delivered to the power that flows into respectively the input gear 41 of the gear pair 4 that cooperates separately again, 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 accelerate, the rotating speed of each output pinion 23 that links with it also increases gradually from zero, at this moment, power is divided into two-way, flowing into each power that connects planet carrier 25 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 23 was identical with the rotating speed of inputting gearwheel 21, each connection planet carrier 25 did not recur and increases the square effect.
