Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed description:
Embodiment:
As shown in fig. 1; A kind of composite cone disk and ring disk type stepless variable speed unit; Comprise input shaft 1, overrunning clutch 3, cone disk and ring disk type stepless variable speed unit 4, gear pair 5, output shaft 6; The output gear 52 of said each gear pair 5 all connects with output shaft 6; Be provided with input gear 21, output planetary frame 22, planetary pinion 23, output gear 24, conjugation tooth ring 25 between described input shaft 1 and the output shaft 6; First input gear 21 connects with input shaft 1; First output planetary frame 22 connects with first input gear 21 that cooperates, first output gear 24, first conjugation tooth ring 25 through two groups of planetary pinions 23 on it; First output gear 24 connects with second input gear 21; Second output planetary frame 22 connects through two groups of planetary pinions 23 on it and second the input gear that cooperates 21, second output gear 24, second conjugation tooth ring 25, and second output gear 24 connects with the 3rd input gear 21, and two groups of planetary pinions 23 that the 3rd output planetary frame 22 passes through on it are imported gear 21, the 3rd output gear 24, the 3rd conjugation tooth ring 25 connections with the 3rd that cooperates; The 3rd output gear 24 connects with the input end 41 of cone disk and ring disk type stepless variable speed unit 4; The output terminal 42 of cone disk and ring disk type stepless variable speed unit 4 and first output planetary frame 22 and second output planetary frame 22 respectively with input gear 51 connections of the gear pair that cooperates separately 5,22 on the 3rd output planetary frame connects with the input end 31 of overrunning clutch 3, the output terminal 32 of overrunning clutch 3 connects with input shaft 1.
Input power splits into two-way by first input gear 21, and one the road flows into first output planetary frame 22, and another road splits into two-way again through first conjugation tooth ring 25; One the road flows into first output planetary frame 22, and another road flows into first output gear 24, flows into second input gear 21 again; Second input gear 21 splits into two-way again, and one the road flows into second output planetary frame 22, and another road splits into two-way again through second conjugation tooth ring 25; One the road flows into second output planetary frame 22; Another road flows into second output gear 24, flows into 21, the three inputs of the 3rd input gear gear 21 again and splits into two-way again; One the road flows into the 3rd output planetary frame 22; Another road splits into two-way again through the 3rd conjugation tooth ring 25, and one the road flows into the 3rd output planetary frame 22, and another road flows into the 3rd output gear 24.
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 gear 21 from zero; Thereby the gear pair 5 of each different drive ratios can be connected simultaneously with output shaft 6; Because of each conjugation tooth ring 25 plays speed governing, make the rotating speed of each input gear 21 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 planetary frame 22 rotating speeds are zero; Its output power is zero, but moment is non-vanishing, at this moment; The input power of each conjugation tooth ring 25 then changes to maximum value by certain value; Described certain value refers to rotating speed when each conjugation tooth ring 25 and the output planetary frame 22 that cooperates separately when identical, and both press the value that planet row torque ratio distributes the input power gained, and described maximum value refers to the total output of being imported by the input gear that cooperates separately 21; That is to say; When two-way power changes, each conjugation tooth ring 25 will play bending moment, and its moment that is delivered on each output planetary frame 22 and the output shaft 6 is also changed thereupon.
The input power of motor splits into two-way through first input gear 21, and one the road flows into first output planetary frame 22, and another road splits into two-way again through first conjugation tooth ring 25; One the road flows into first output planetary frame 22, and another road flows into first output gear 24, flows into second input gear 21 again; Second input gear 21 splits into two-way again, and one the road flows into second output planetary frame 22, and another road splits into two-way again through second conjugation tooth ring 25; One the road flows into second output planetary frame 22, and another road flows into second output gear 24, flows into the 3rd input gear 21 again; The 3rd input gear 21 splits into two-way again, and one the road flows into the 3rd output planetary frame 22, and another road splits into two-way again through the 3rd conjugation tooth ring 25; One the road flows into the 3rd output planetary frame 22; Another road flows into the 3rd output gear 24, and wherein, the power that flow into the 3rd output planetary frame 22 is delivered to input shaft 1 through overrunning clutch 3; Conflux with the input power of motor; The power that flow into the 3rd output gear 24 is then through the input end 41 of cone disk and ring disk type stepless variable speed unit 4, and through the output terminal 42 of cone disk and ring disk type stepless variable speed unit 4, it is delivered to the input gear 51 of the gear pair 5 of cooperation separately to the power that flows into respectively again with first output planetary frame 22 and second output planetary frame 22 again; Output gear 52 through each gear pair 5 confluxes to output shaft 6 of the present invention again, thereby has realized externally exporting the power of motor through output shaft 6.
For the present invention; When the rotating speed of input shaft 1 is constant, the moment of torsion on the output shaft 6 changes with its change in rotational speed, and rotating speed is low more; Moment of torsion on the output shaft 6 is just big more; Otherwise, then more little, thus realize that the present invention can change the composite cone disk and ring disk type stepless variable speed unit of moment and speed with the difference of vehicle driving resistance.
When the present invention uses, the input power, input speed of establishing motor with and load constantly, promptly the rotating speed of input shaft 1 and moment of torsion are constant; Before the vehicle starting, the rotating speed of output shaft 6 is zero, works as automobile starting; Because of output shaft 6 transfixions, i.e. each output planetary frame 22 transfixions, power of each input gear 21 all flows into the conjugation tooth rings 25 that cooperate separately; Moment of torsion is increased, and be divided into two-way, the one tunnel is delivered to the output gear 24 that cooperates separately; Another road is delivered to the output planetary frame 22 that cooperates separately, and wherein, the 3rd output gear 24 flow into power the input end 41 of cone disk and ring disk type stepless variable speed unit 4; Through the output terminal 42 of cone disk and ring disk type stepless variable speed unit 4, it is delivered to the input gear 51 of the gear pair 5 of cooperation separately to the power that flows into respectively again with first output planetary frame 22 and second output planetary frame 22 again, and the output gear 52 through each gear pair 5 confluxes to output shaft 6 again; When the moment of torsion that is delivered on the output shaft 6, when power train was transferred to the tractive force that produces on the driving wheel and is enough to overcome the vehicle starting resistance, automobile then started to walk and begins to quicken; The rotating speed of each output planetary frame 22 that links with it also increases from zero gradually, and at this moment, power is divided into two-way; The power that flows into each conjugation tooth ring 25 reduces gradually, thereby, its square effect that increases is reduced gradually; The moment of torsion of output shaft 6 reduces along with the increase of rotating speed, and when relevant output planetary frame 22 was identical with the rotating speed of importing gear 21, each conjugation tooth ring 25 did not recur and increases the square effect.
