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 sealed planetary cone type stepless variable speed unit, comprise input shaft 1, gear pair 3, sealed planetary cone type stepless variable speed unit 4, output shaft 5, the output gear 32 of described each gear pair 3 connects with output shaft 5, be provided with input bull gear 21 between described input shaft 1 and output shaft 5, first connects planet carrier 22a, second connects planet carrier 22b, planetary pinion 23, connect bull gear 24, first output gear 25a, second output gear 25b, output bull gear 26, input bull gear 21 connects with input shaft 1, first connects planet carrier 22a by two groups of planetary pinions 23 on it and the input bull gear 21 that coordinates, connecting large wheel rim 24 and first output gear 25a connects, second connects planet carrier 22b by two groups of planetary pinions 23 on it and the connection bull gear 24 that coordinates, second output gear 25b connects with output bull gear 26, output bull gear 26 connects with the input end 41 of sealed planetary cone type stepless variable speed unit 4, the output terminal 42 of sealed planetary cone type stepless variable speed unit 4 and first output gear 25a and second output gear 25b connect with the input gear 31 of the gear pair 3 that coordinates separately respectively, first output gear 25a connects two groups of planetary pinions, 23 engagements on planet carrier 22a simultaneously with first, two groups of planetary pinions 23 that second output gear 25b connects with second on planet carrier 22b simultaneously mesh.
Input power splits into two-way by input bull gear 21, one the road flows into first output gear 25a, another road flows into first and connects planet carrier 22a, then splits into two-way, and one the road flows into first output gear 25a, another road flows into connection bull gear 24 and splits into two-way again, one the road flows into second output gear 25b, and another road flows into second and connects planet carrier 22b, then splits into two-way, one the road flows into second output gear 25b, and another road flows into output bull gear 26.
Because the rotating speed relations of distribution of above-mentioned each element can change, so the rotating speed of first output gear 25a and second output gear 25b can constantly change in the scope identical with the rotating speed of input bull gear 21 from zero, thereby the gear pair 3 of each different drive ratios can be connected with output shaft 5 simultaneously, and this is to connect planet carrier 22a and second connection planet carrier 22b plays speed governing because of first.
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 first output gear 25a and second output gear 25b rotating speed are zero, its output power is zero, but moment is non-vanishing, at this moment, the input power that connects bull gear 24 and output bull gear 26 changes to maximum value by certain value, described certain value refers to when connecting bull gear 24 and output bull gear 26 and the output gear 25a that coordinates separately, when the rotating speed of 25b is identical, both press the value that the planet row torque ratio distributes the input power gained, described maximum value refers to the connection planet carrier 22a that connects by separately, the total output of 22b input, that is to say, when two-way power changes, connect bull gear 24 and export bull gear 26 and will play bending moment, its moment that is delivered on second output gear 25b and sealed planetary cone type stepless variable speed unit 4 and output shaft 5 is also changed thereupon.
the input power of motor splits into two-way through input bull gear 21, one the road flows into first output gear 25a, another road flows into first and connects planet carrier 22a, split into again two-way, one the road flows into first output gear 25a, another road flows into connection bull gear 24 and splits into two-way again, one the road flows into second output gear 25b, another road flows into second and connects planet carrier 22b, split into again two-way, one the road flows into second elm goes out gear ring 25b, another road flows into output bull gear 26, output bull gear 26 flows into the input end 41 of sealed planetary cone type stepless variable speed unit 4 again, again through the output terminal 42 of sealed planetary cone type stepless variable speed unit 4, it is delivered to the power that flows into respectively the input gear 31 of the gear pair 3 that coordinates separately again with first output gear 25a and second output gear 25b, output gear 32 through each gear pair 3 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 rolling cone flat disk 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 output gear 25a, the 25b transfixion, connect planet carrier 22a, the power of 22b all flows into and connects bull gear 24 or output bull gear 26, after connecting bull gear 24 and output bull gear 26 bending moments, moment of torsion is increased, at this moment, connect bull gear 24 and split into again two-way, one the tunnel is delivered to second connects planet carrier 22b, another road is delivered to second output gear 25b, wherein, output bull gear 26 flows into power the input end 41 of sealed planetary cone type stepless variable speed unit 4, again through the output terminal 42 of sealed planetary cone type stepless variable speed unit 4, it is delivered to the power that flows into respectively the input gear 31 of the gear pair 3 that coordinates separately again with first output gear 25a and second output gear 25b, output gear 32 through each gear pair 3 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 output gear 25a that links with it, the rotating speed of 25b also increases gradually from zero, at this moment, power is divided into two-way, flowing into each connects bull gear 24 and exports mutually the power of bull gear 26 and reduce gradually, thereby, the square effect that increases that connects bull gear 24 and output bull gear 26 is reduced gradually, the moment of torsion of output shaft 5 reduces along with the increase of rotating speed, as relevant output gear 25a, when 25b is identical with the rotating speed of inputting bull gear 21, connection bull gear 24 and output bull gear 26 do not recur and increase the square effect.
