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 coupler, it comprises input shaft 1, joiner 3, coupler 4, output shaft 5, the output terminal 42 of described coupler 4 connects with output shaft 5, be provided with input planet carrier 21 between input shaft 1 and the output shaft 5, output planetary frame 22, planetary pinion 23, public output gear shaft 24, gearwheel 25, input planet carrier 21 connects with input shaft 1, and by planetary pinion 23 and public output gear shaft 24 on the input planet carrier 21, gearwheel 25 connects, gearwheel 25 is by another group planetary pinion 23 and output planetary frame 22 on the output planetary frame 22, public output gear shaft 24 connects, output planetary frame 22 connects with the input end 31 of joiner 3, the output terminal 32 of joiner 3 connects with the input end 41 of input planet carrier 21 and coupler 4 respectively, and 24 of public output gear shafts connect with output shaft 5.
Described joiner 3 is selected overrunning clutch for use.
Because the rotating speed relations of distribution between 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 public output gear shaft 24 rotating speeds are zero, its input power is zero, but moment is non-vanishing, at this moment, the input power of gearwheel 25 then changes to maximum value by certain value, described certain value refers to rotating speed when public output gear shaft 24 and gearwheel 25 when identical, both press the value that planet row torque ratio distributes the input power gained, described maximum value refers to the total output by the motor input, that is to say, when two-way power changes, gearwheel 25 will play the bending moment effect, and its moment that is delivered on public output gear shaft 24 and the output shaft 5 is also changed thereupon.
The input power of motor splits into two-way through input planet carrier 21, one the road flows into public output gear shaft 24, another road flows into gearwheel 25, this power splits into two-way again, one the road flows into public output gear shaft 24, another road flows into the input end 31 of joiner 3 through output planetary frame 22, split into two-way by joiner 3 output terminals 32 again, one the road flows into input planet carrier 21 confluxes with the input power of motor, and repeat above-mentioned shunting process, another road flows into the input end 41 of coupler 4, output terminal 42 through coupler 4 is delivered to output shaft 5 again, and realize confluxing, thereby realized that the power of motor is passed through output shaft 5 externally to be exported with public output gear shaft 24 one tunnel.
For the present invention, when the rotating speed of input shaft 1 is constant, the moment of torsion on the output shaft 5 changes with its change in rotational speed, rotating speed is low more, and the input torque of output shaft 5 is just big more, otherwise, then more little, thus realize that the present invention can be with the different couplers that change moments of Vehicle Speed and resistance.
When the present invention uses, if the input power of motor, input speed 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 public output gear shaft 24 transfixions, the power of motor all flows into gearwheel 25, make the input torque of moment of torsion behind its bending moment greater than motor, and be divided into two-way, one the tunnel is delivered to public output gear shaft 24, another road is delivered to output planetary frame 22, through joiner 3 moment of torsion is divided into two-way again, one the tunnel is delivered to the input end 41 of coupler 4, be delivered to output shaft 5 through the output terminal 42 of coupler 4 and realize that with public output gear shaft 24 one tunnel moments of torsion converge, another road is delivered to input planet carrier 21 and realizes converging with the input torque of motor, and between each element, constantly carry out the branch square, the circulation repeatedly of bending moment and remittance square, the moment of torsion that is delivered to public output gear shaft 24 is constantly increased, and be delivered to output shaft 5, when the moment of torsion that is delivered on the output shaft 5, 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, and the rotating speed of the public output gear shaft 24 that links with it also increases gradually from zero, at this moment, power is divided into two-way, and the power that flows into gearwheel 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, and when input shaft 5 was identical with the rotating speed of importing planet carrier 21, gearwheel 25 did not recur and increases the square effect.
