Accompanying drawing explanation
Fig. 1 is the structural drawing of the embodiment of the present invention one;
Joint in accompanying drawing between two elements, use heavy line to represent and be fixedly connected with, fine line represents that two elements can relatively rotate.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Embodiment one:
As shown in fig. 1, a kind of compound adjustable hydraulic torque converter, comprises input shaft 1, adjustable hydraulic torque converter 3, overrunning clutch 4, output shaft 5, gear pair 6, is provided with between described input shaft 1 and output shaft 5 and inputs little gear ring 21, planetary pinion 22, fixing bull gear 23, export little gear ring 24, interlock planet carrier 25, conflux little gear ring 26, export bull gear 27, conflux planet carrier 28, and the input gear 61 inputting little gear ring 21 and gear pair 6 connects with input shaft 1, and interlock planet carrier 25 is by the two groups of planetary pinions 22 on it and the little gear ring 21 of input, fixing bull gear 23, export little gear ring 24 cooperating, export little gear ring 24 to connect with the input end 31 of adjustable hydraulic torque converter 3, the output terminal 32 of adjustable hydraulic torque converter 3 connects with the input end 41 of overrunning clutch 4 and the planet carrier 28 that confluxes, output terminal 42 and the fixing bull gear 23 of overrunning clutch 4 connect with fixed element, and the planet carrier 28 that confluxes is by the planetary pinion 22 on it and the little gear ring 26 that confluxes coordinated, export bull gear 27 cooperating, the little gear ring 26 that confluxes connects with the output gear 62 of gear pair 6, exports bull gear 27 and connects with output shaft 5.
The input power of motor splits into two-way, the first via, flows into by gear pair 6 the little gear ring 26 that confluxes; Second tunnel, flows into the little gear ring 21 of input, then the two groups of planetary pinions 22 passed through on interlock planet carrier 25 flow into interlock planet carriers 25, then flows into the little gear ring 24 of output, and is delivered to adjustable hydraulic torque converter 3, then flows into the planet carrier 28 that confluxes.
Owing to confluxing, little gear ring 26 and the planet carrier 28 that confluxes are the elements that conflux, so the first via flows into the power of the little gear ring 26 that confluxes and flows into the second tunnel and to conflux the power of planet carrier 28, then conflux in output bull gear 27, and be delivered to output shaft 5, thus achieve the power of motor is externally exported by output shaft 5.
For compound adjustable hydraulic torque converter of the present invention, when the rotating speed of input shaft 1 is constant, moment of torsion on output shaft 5 changes with the change of its rotating speed, rotating speed is lower, moment of torsion on output shaft 5 is larger, otherwise, then less, thus realize the present invention can change moment and speed compound adjustable hydraulic torque converter with the difference of vehicle travel resistance.
When compound adjustable hydraulic torque converter of the present invention uses, if the input power of motor, input speed and its load constant, namely the rotating speed of input shaft 1 and moment of torsion are constant, before vehicle starting, the rotating speed of output shaft 5 is zero, work as automobile starting, because resistance is larger, and due to the effect of overrunning clutch 4, to conflux planet carrier 28 transfixion, conflux little gear ring 26 being delivered to this moment of torsion by gear pair 6 from input shaft 1, be delivered to again and export bull gear 27, output bull gear 27 reduction of speed is made to increase square, and be delivered to output shaft 5, through power train be transferred to the tractive force that driving wheel produces be enough to overcome vehicle starting resistance time, automobile is then started to walk and is started to accelerate, when increasing power and continuing acceleration or drag reduction, overrunning clutch 4 automatically terminates the control to planet carrier 28 sense of rotation of confluxing, the input end 31 of adjustable hydraulic torque converter 3 and the speed discrepancy of output terminal 32 constantly reduce, namely the rotating speed of planet carrier 28 of confluxing constantly increases, and converge speed in exporting bull gear 27 with the rotating speed of the little gear ring 26 that confluxes, the rotating speed of output bull gear 27 is also constantly increased, and be transferred to output shaft 5, thus achieve the power of motor is externally exported by output shaft 5.
