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 inner cone output planetary cone type stepless variable speed unit, comprise input shaft 1, inner cone output planetary 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 the little gear ring 21 of input between described input shaft 1 and output shaft 5, output planetary frame 22, planetary pinion 23, connect bull gear 24, export little gear ring 25, the little gear ring 21 of first input connects with input shaft 1, first output planetary frame 22 by two groups of planetary pinions 23 on it with coordinate first input little gear ring 21, first connects bull gear 24 and the little gear ring 25 of first output connects, second output planetary frame 22 inputted little gear ring 21 by two groups of planetary pinions 23 on it with second that coordinates, second connects bull gear 24 and second little gear ring 25 connection of output, the little gear ring 25 of first output connects with second little gear ring 21 of input, second little gear ring 25 of output connects with the input end 31 of inner cone output planetary cone type stepless variable speed unit 3, the output terminal 32 of inner cone output planetary cone type stepless variable speed unit 3 and each output planetary frame 22 connect with the input gear 41 of the gear pair 4 that coordinates separately.
input power splits into two-way by the little gear ring 21 of first input, one the road flows into first output planetary frame 22, another road connects bull gear 24 through first and splits into two-way again, one the road flows into first output planetary frame 22, another road flows into the little gear ring 25 of first output, flow into again second little gear ring 21 of input, second little gear ring 21 of input splits into two-way again, one the road flows into second output planetary frame 22, another road connects bull gear 24 through second and splits into two-way again, one the road flows into second output planetary frame 22, another road flows into second little gear ring 25 of output.
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 the little gear ring 21 of each input 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 bull gear 24, make the rotating speed of the little gear ring 21 of each input 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 that connects bull gear 24 changes to maximum value by certain value, described certain value refers to when each and connects the rotating speed of bull gear 24 and the output planetary frame 22 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 little gear ring 21 inputs of the input that connects separately, that is to say, when two-way power changes, each connects bull gear 24 will play bending moment, its moment that is delivered on each output planetary frame 22 and output shaft 5 is also changed thereupon.
the input power of motor splits into two-way through the little gear ring 21 of first input, one the road flows into first output planetary frame 22, another road connects bull gear 24 through first and splits into two-way again, one the road flows into first output planetary frame 22, another road flows into the little gear ring 25 of first output, flow into again second little gear ring 21 of input, second little gear ring 21 of input splits into two-way again, one the road flows into second output planetary frame 22, another road connects bull gear 24 through second and splits into two-way again, one the road flows into second output planetary frame 22, another road flows into second little gear ring 25 of output, second little gear ring 25 of output flows into the input end 31 of inner cone output planetary cone type stepless variable speed unit 3 again, again through the output terminal 32 of inner cone output planetary cone 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 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 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 inner cone output planetary 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 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 the little gear ring 21 of each input all flows into each and connects bull gear 24, moment of torsion is increased, and be divided into two-way, one the tunnel is delivered to the little gear ring 25 of output that coordinates separately, another road is delivered to the output planetary frame 22 that coordinates separately, wherein, second little gear ring 25 of output flows into power the input end 31 of inner cone output planetary cone type stepless variable speed unit 3, again through the output terminal 32 of inner core output planetary conical 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 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 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 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 that connects bull gear 24 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 planetary frame 22 is identical with the rotating speed of inputting little gear ring 21, each connection bull gear 24 does not recur and increases the square effect.
