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 steel ball inner cone gear type stepless variable speed unit, comprise input shaft 1, steel ball inner cone gear 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 bull gear 21 between described input shaft 1 and the output shaft 5, output planetary frame 22, output bull gear 23, output gear 24, input little gear ring 25, planetary pinion 26, first input bull gear 21 connects with input shaft 1, first output planetary frame 22 by two groups of planetary pinions 26 on it with cooperate first input bull gear 21, first output gear 24, first inputs little gear ring 25, first output bull gear 23 connects, first output gear 24 is inputted little gear ring 25 with first and is connected, first output bull gear 23 and second input bull gear 21, second output planetary frame 22 inputted bull gear 21 by two groups of planetary pinions 26 on it with second that cooperates, second output gear 24, second little gear ring 25 of input, second output bull gear 23 connects, second output gear 24 and second little gear ring 25 of input connect, second output bull gear 23 connects with the input end 31 of steel ball inner cone gear type stepless variable speed unit 3, and the output terminal 32 of steel ball inner cone gear type stepless variable speed unit 3 and each output planetary frame 22 connect with the input gear 41 of the gear pair 4 that cooperates separately respectively.
Input power splits into two-way by first input bull gear 21, one the road flows into first output planetary frame 22, another road is through first output gear 24, flow into again first and input little gear ring 25, first is inputted little gear ring 25 and splits into two-way again, one the road flows into first output planetary frame 22, another road flows into first output bull gear 23, flow into again second input bull gear 21, second input bull gear 21 splits into two-way again, one the road flows into second output planetary frame 22, another road flows into 25, the second little gear rings 25 of input of second little gear ring of input again and splits into two-way again through second output gear 24, one the road flows into second output planetary frame 22, and another road flows into second output bull gear 23.
Because the rotating speed relations of distribution of above-mentioned each element can change, so the rotating speed of each output planetary frame 22 can constantly change in the scope identical with the rotating speed of each input bull gear 21 from zero, thereby the gear pair 4 of each different drive ratios can be connected simultaneously with output shaft 5, input little gear ring 25 because of each and play speed governing, make the rotating speed of each input bull gear 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 planetary frame 22 rotating speeds are zero, its output power is zero, but moment is non-vanishing, at this moment, each input power of inputting little gear ring 25 then changes to maximum value by certain value, described certain value refers to when each and inputs the rotating speed of little gear ring 25 and the output planetary frame 22 that cooperates 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 bull gear 21 inputs that cooperate separately, that is to say, when two-way power changes, each inputs little gear ring 25 will play speed change, increase the effect of square, its moment that is delivered on each output planetary frame 22 and the output shaft 5 is also changed thereupon.
The input power of motor splits into two-way through first input bull gear 21, one the road flows into first output planetary frame 22, another road is through first output gear 24, flow into again first and input little gear ring 25, first is inputted little gear ring 25 and splits into two-way again, one the road flows into first output planetary frame 22, another road flows into first output bull gear 23, flow into again second input bull gear 21, second input bull gear 21 splits into two-way again, one the road flows into second output planetary frame 22, another road is through second output gear 24, flow into again second little gear ring 25 of input, second little gear ring 25 of input splits into two-way again, one the road flows into second output planetary frame 22, another road flows into second output bull gear 23, second output bull gear 23 flows into the input end 31 of steel ball inner cone gear type stepless variable speed unit 3 again, again through the output terminal 32 of steel ball inner cone gear type stepless variable speed unit 3, it is delivered to the separately input gear 41 of the gear pair 4 of cooperation to the power that flows into respectively again with first output planetary frame 22 and second output planetary frame 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 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 ball inner cone gear 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 planetary frame 22 transfixions, the power of each input planet carrier 21 all flows into the little gear ring 25 of input that cooperates separately, moment of torsion is increased, and be divided into two-way, one the tunnel is delivered to the output planetary frame 22 that cooperates separately, another road is delivered to the output bull gear 23 that cooperates separately, wherein, second output bull gear 23 flows into power the input end 31 of steel ball inner cone gear type stepless variable speed unit 3, again through the output terminal 32 of steel ball inner cone gear type stepless variable speed unit 3, it is delivered to the separately input gear 41 of the gear pair 4 of cooperation to the power that flows into respectively again with first output planetary frame 22 and second output planetary frame 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 accelerate, the rotating speed of each output planetary frame 22 that links with it also increases gradually from zero, at this moment, power is divided into two-way, flowing into each power of inputting little gear ring 25 reduces gradually, thereby, its accelerating function is reduced gradually, the moment of torsion of output shaft 5 reduces along with the increase of rotating speed, when relevant output planetary frame 22 was identical with the rotating speed of inputting bull gear 21, each inputted little gear ring 25 speed change that do not recur, increase the effect of square.
