Embodiment one:
As shown in fig. 1, a kind of compound double-impeller torque converter, comprises input shaft 1, output gear wheel set 3, overrunning clutch 4, double-impeller torque converter 5, input gear pair 6, output shaft 8, is provided with between described input shaft 1 and output shaft 8 and inputs gearwheel 20, planetary pinion 21, output gear 22, output planetary frame 23, connect gearwheel 24, connect gear 25, fixed carrier 26, conflux output gear 27, conflux gear 28, conflux planet carrier 29, and input gearwheel 20 connects with input shaft 1, and output planetary frame 23 is by the planetary pinion 21 on it and input gearwheel 20, output gear 22 cooperating, output gear 22 with connect gearwheel 24 and connect, fixed carrier 26 by the planetary pinion 21 on it with connect gearwheel 24, connect gear 25 cooperating, connect gear 25 to connect with the planet carrier 29 that confluxes, output planetary frame 23 connects with the input gear 61 of input gear pair 6, the output gear 62 of input gear pair 6 connects with the input end 51 of double-impeller torque converter 5, the output terminal 52 of double-impeller torque converter 5 connects with the input gear 31 of the input end 41 of overrunning clutch 4 and output gear wheel set 3, output terminal 42 and the fixed carrier 26 of overrunning clutch 4 connect with fixed element, the output gear 32 of output gear wheel set 3 connects with the gear 28 that confluxes, and the planet carrier 29 that confluxes is by the planetary pinion 21 on it and the output gear 27 that confluxes, conflux gear 28 cooperating, and the output gear 27 that confluxes connects with output shaft 8.
The input power of motor flows into input gearwheel 20 through input shaft 1, two-way is split into again by the planetary pinion 21 on output planetary frame 23, the first via, flow into output gear 22, flow into again and connect gearwheel 24, flowed into by the planetary pinion 21 in fixed carrier 26 again and connect gear 25, then flow into the planet carrier 29 that confluxes; Second tunnel, flows into output planetary frame 23, and flows into double-impeller torque converter 5 by input gear secondary 6, then flows into output gear wheel set 3 and the gear 28 that confluxes.
Owing to confluxing, gear 28 and the planet carrier 29 that confluxes are the elements that conflux, so flow into the first via conflux planet carrier 29 power and flow into the second tunnel and to conflux the power of gear 28, then conflux in output gear 27, and be delivered to output shaft 8, thus achieve the power of motor is externally exported by output shaft 8.
For compound double-impeller torque converter of the present invention, when the rotating speed of input shaft 1 is constant, moment of torsion on output shaft 8 changes with the change of its rotating speed, rotating speed is lower, moment of torsion on output shaft 8 is larger, otherwise, then less, thus realize the present invention can change moment and speed compound double-impeller torque converter with the difference of vehicle travel resistance.
Compound double-impeller torque converter when 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 8 is zero, work as automobile starting, because resistance is larger, and due to the effect of overrunning clutch 4, to conflux gear 28 transfixion, conflux planet carrier 29 being delivered to this moment of torsion by each element from input shaft 1, be delivered to output gear 27 again, output gear 27 reduction of speed is made to increase square, and be delivered to output shaft 8, 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 gear 28 sense of rotation of confluxing, the input end 51 of double-impeller torque converter 5 and the speed discrepancy of output terminal 52 constantly reduce, namely the rotating speed of gear 28 of confluxing constantly increases, and converge speed in output gear 27 with the rotating speed of the planet carrier 29 that confluxes, the rotating speed of output gear 27 also constantly increases, and be transferred to output shaft 8, thus achieve the power of motor is externally exported by output shaft 8.
