Embodiment
Torque-converters of the present invention as shown in Figures 2 to 7, comprising: protecgulum 100, fore shell 200, turbine 300 and stator 400.
First the black heavy solid line arrows in accompanying drawing is the flow direction of oil, and solid arrows is sense of rotation.
Protecgulum 100 is combined on the live axle S1 of engine.
Above-mentioned protecgulum 100 as shown in Figure 2, is combined with fore shell 200, is combined roughly in sweet loop-shaped with fore shell 200.
Fore shell 200 is combined with protecgulum 100.
Fore shell 200 is combined with protecgulum 100, roughly in sweet loop-shaped, and cross section semicircular in shape.
In the inner side of fore shell 200, as shown in Figures 2 to 4, there is the first impeller 210 and the first guide portion 220.
First impeller 210 is made up of a plurality of, when fore shell 200 rotates, because the center of circle power of oil sprays laterally.
The oil sprayed because of the first impeller 210, turbine 300 described later rotates.
First guide portion 220 fixes the end of the end of the first impeller 210, and guides oil.
That is, the first guide portion 220 is when oil sprays because of center of circle power, and because of the center of circle power shown in figure bis-, the oil of movement laterally can not form eddy current, can move along the inner edge of fore shell 200.
As shown in Figure 2, in arcuation, protuberance 410 described later configures within it first guide portion 220.
Turbine 300 and fore shell 200 subtend, namely cross section is curved, as shown in Figure 2, is configured in the inner side of protecgulum 100, is combined on output shaft S2.
Above-mentioned turbine 300, as shown in Fig. 2, Fig. 3 and Fig. 5, has the first blade 310, second guide portion 320, second impeller 330 and the 3rd guide portion 340.
First blade 310 is fixed in the inner side of turbine 300, for a plurality of.
Above-mentioned first blade 310 is when fore shell 200 rotates, and the oil sprayed because of the first impeller 210 bumps against with it, and turbine 300 is rotated, and the output shaft S2 be combined on turbine 300 is rotated.
Second guide portion 320 fixes the end of the first blade 310, and guides oil.
Further, the second guide portion 320 as shown in figures 2 and 5, when oil collision is moved on the first blade 310, can not produce the eddy current of oil, can move along the inner edge of turbine 300.
Second impeller 330 is fixed on the inner side of the second guide portion 320, for a plurality of.
As shown in Figure 2, when turbine 300 rotates, the oil inside the second guide portion 320 sprays because of center of circle power above-mentioned second impeller 330 laterally.
Because of the oil that the second impeller 330 sprays, stator 400 described later is rotated.
As shown in Figure 5, in outward direction, namely the opposite direction of the sense of rotation of turbine 300 tilts to form spinning center line second impeller 330.
In outward direction, namely the opposite direction of the sense of rotation of turbine 300 tilts to form second impeller 330 factor rotation center line, and therefore, when rotated, the Inside To Outside direction of the second guide portion 320, oil more effectively sprays turbine 300, and stator 400 more effectively rotates.
3rd guide portion 340 is fixed the end of the second impeller 330 at the end of a plurality of second impeller 330 and guides oil.
Above-mentioned 3rd guide portion 340, because of the rotation of turbine 300, makes the oil sprayed from the second impeller 330 can not eddy current, can move along the inner edge of the second guide portion 320.
Stator 400 is configured between the inner circumferential of fore shell 200 and turbine 300 inner circumferential, can change the flow direction of oil.
Further, stator 400, as shown in Fig. 2, Fig. 5 and Fig. 6, can change the flow direction from the first blade 310 oil out, and oil is supplied on the first impeller 210 of fore shell 200 again.
Further, stator 400 is made up of a direction clutch that can not reverse.
Stator 400 together rotates with fore shell 200 and turbine 300, farthest can improve the reception and registration efficiency of moment of torsion.
Turbine 300 as shown in Figure 2, Figure 6 and Figure 7, is made up of protuberance 410, second blade 420 and the 4th guide portion 430.
Protuberance 410, on edge, the periphery of stator 400, forms with the second guide portion 320 subtend is outstanding.
Further, protuberance 410 and the second guide portion 320 subtend, that is, correspondingly with the first guide portion to form, be configured in the inner side of the first guide portion 220.
Second blade 420, on the inner side of protuberance 410, for a plurality of, is fixed on protuberance 410 with the second impeller 330 subtend.
As shown in FIG. 6 and 7, the oil sprayed from the second impeller 330 bumps against with it above-mentioned second blade 420, and stator 400 is rotated.
As mentioned above, because of above-mentioned second impeller 330 and the second blade 420, stator 400 rotates, and makes stator 400 force to rotate, shortens the time point of rotation, farthest improve the reception and registration efficiency of moment of torsion.
4th guide portion 430, at the end of the second blade 420, with the 3rd guide portion 340 subtend, fixes the end of the second blade 420, and guides oil.
Further, the 4th guide portion 430 can guide the oil inside the second blade 420 not form eddy current etc., but moves along the inner edge of protuberance 410.
In addition, the cross section of the 3rd guide portion 340 and the 4th guide portion 430 is arcuation, roughly rounded as shown in Figure 2.
Because of above-mentioned 3rd guide portion 340 and the 4th guide portion 430 roughly rounded, oil can be made to rotate along the inner edge of the first guide portion 220 and the second guide portion 320.
Next, flowing and the course of action of the oil of the torque-converters of said structure and formation are described.
First, the black thick-line arrow in accompanying drawing is the flow direction of oil.
After engine drives, be connected to protecgulum 100 on engine live axle S1 and fore shell 200 starts to rotate.
Now, because of the rotation of fore shell 200, oil produces center of circle power, thus oil is sprayed laterally along the first impeller 210.
The oil of such ejection and the first blade 310 of turbine 300 bump against, and pass on power to turbine 300 and rotate, the output shaft S2 be combined with turbine 300 starts to rotate.
Oil is inside the inner edge of turbine 300, and namely rotation centerline moves, and the oil of movement like this changes direction because of stator 400, then moves to the first impeller 210, and said process repeatedly.
In addition, when turbine 300 rotates, the second impeller 330 of turbine 300 makes the oil of the inner side of the second guide portion 320 because of the lateral direction ejection of center of circle power i.e. rotation centerline in outward direction.
The oil of such ejection and the second blade 420 of protuberance 410 bump against, thus the stator 400 of formation protuberance 410 is rotated.
By the repeatable operation of said process, stator 400 is forced to rotate, thus can shorten the rotation time point of stator 400, the reception and registration efficiency of maximum raising moment of torsion.
Illustrate, in conventional art, when the speed ratio of live axle S1 and the speed ratio of output shaft S2 are 10 to 5, the oily integral-rotation of torque-converters inside, stator 400 rotates, and reaches maximum moment of torsion and passes on efficiency.But, in the present invention, because of the second impeller 330 and the second blade 420, the speed ratio of live axle S1 and the speed ratio of output shaft S2 reach before 10 to 5, namely before the oily integral-rotation of torque-converters inside, stator 400 starts to rotate, and the rotation time point of stator 400 is shortened, and at utmost can improve the reception and registration efficiency of moment of torsion.
Further, as shown in Figure 5, spinning center line in outward direction for the second impeller 330, the opposite direction of the sense of rotation of turbine 300 tilts to form, because of the second impeller 330, the ejection in outward direction that oil can be stronger, thus farthest shorten the rotation time point of stator 400.
Torque-converters of the present invention is not limited to above-mentioned mode of execution, as long as all replacements, change, distortion etc. within the scope of technological thought of the present invention and spiritual principles all belong to protection category of the present invention.
