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 composite impeller type hydraulic torque converter, comprises input shaft 1, output gear wheel set 3, impeller Hydraulic torque converter 4, overrunning clutch 5, input gear pair 6, output shaft 7, is provided with planetary pinion 20 between described input shaft 1 and output shaft 7, line of input carrier 21, shunting bull gear 22, shunt little gear ring 23, connect bull gear 24, input small gear 25, fixed carrier 26, conflux gear 27, conflux gear ring 28, output planetary frame 29, line of input carrier 21 connects with input shaft 1, and line of input carrier 21 is by the planetary pinion 20 on it and shunting bull gear 22, shunt little gear ring 23 cooperating, shunting bull gear 22 connects with the input gear 31 of output gear wheel set 3, the output gear 32 of output gear wheel set 3 with input small gear 25 and connect, fixed carrier 26 is passed through planetary pinion 20 on it and is connected bull gear 24, input small gear 25 cooperating, connect bull gear 24 to connect with the gear 27 that confluxes, shunt little gear ring 23 to connect with the input end 41 of impeller Hydraulic torque converter 4, the output terminal 42 of impeller Hydraulic torque converter 4 connects with the input gear 61 of the input end 51 of overrunning clutch 5 and input gear pair 6, output terminal 52 and the fixed carrier 26 of overrunning clutch 5 connect with fixed element, the output gear 62 of input gear pair 6 connects with the gear ring 28 that confluxes, and output planetary frame 29 is by the planetary pinion 20 on it and the gear 27 that confluxes, conflux gear ring 28 cooperating, and output planetary frame 29 connects with output shaft 7.
The input power of motor flows into line of input carrier 21 through input shaft 1, and split into two-way by the planetary pinion 20 in line of input carrier 21, the first via, flow into shunting bull gear 22, input small gear 25 is flowed into again through output gear wheel set 3, flowed into by the planetary pinion 20 in fixed carrier 26 again and connect bull gear 24, then flow into the gear 27 that confluxes; Second tunnel, flows into the little gear ring 23 of shunting, then flows into by impeller Hydraulic torque converter 4 and input gear secondary 6 gear ring 28 that confluxes.
Owing to confluxing, gear 27 and the gear ring 28 that confluxes are the elements that conflux, so flow into the first via conflux gear 27 power and flow into the second tunnel and to conflux the power of gear ring 28, then conflux in output planetary frame 29, and be delivered to output shaft 7, thus achieve the power of motor is externally exported by output shaft 7.
For composite impeller type hydraulic torque converter of the present invention, when the rotating speed of input shaft 1 is constant, moment of torsion on output shaft 7 changes with the change of its rotating speed, rotating speed is lower, moment of torsion on output shaft 7 is larger, otherwise, then less, thus realize the present invention can change moment and speed composite impeller type hydraulic torque converter with the difference of vehicle travel resistance.
When composite impeller type 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 7 is zero, work as automobile starting, because resistance is larger, and due to the effect of overrunning clutch 5, to conflux gear ring 28 transfixion, conflux gear 27 being delivered to this moment of torsion by each element from input shaft 1, be delivered to output planetary frame 29 again, output planetary frame 29 reduction of speed is made to increase square, and be delivered to output shaft 7, 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 5 automatically terminates the control to gear ring 28 sense of rotation of confluxing, the input end 41 of impeller Hydraulic torque converter 4 and the speed discrepancy of output terminal 42 constantly reduce, namely the rotating speed of gear ring 28 of confluxing constantly increases, and converge speed in output planetary frame 29 with the rotating speed of the gear 27 that confluxes, the rotating speed of output planetary frame 29 is also constantly increased, and be transferred to output shaft 7, thus achieve the power of motor is externally exported by output shaft 7.
