Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
Embodiment:
As shown in fig. 1, a kind of stepless speed variator of composite type hydraulic torque converter with external overflow valve, comprises input shaft 1, overrunning clutch 4, external hydraulic torque converter of overflow valve 5, input gear pair 6, joining shaft 7, conflux gear pair 8, output shaft 9, is provided with planetary pinion 20 between described input shaft 1 and output shaft 9, fixed carrier 21, export little gear ring 22, input bull gear 23, connect planet carrier 24, connect little gear ring 25, connect bull gear 26, export bull gear 27, conflux gear 28, conflux planet carrier 29, conflux planetary pinion 30, export gearwheel 31, conflux input small gear 32, line of input of confluxing carrier 33, the input gear 61 of input bull gear 23 and input gear pair 6 connects with input shaft 1, and fixed carrier 21 is by the planetary pinion 20 on it and the little gear ring 22 of output, input bull gear 23 cooperating, export little gear ring 22 to connect with the input gear 81 of the gear pair 8 that confluxes, the output gear 82 of gear pair 8 of confluxing inputs small gear 32 and connects with confluxing, the output gear 62 of input gear pair 6 with connect bull gear 26 and joining shaft 7 connects, joining shaft 7 connects with the gear 28 that confluxes, connect planet carrier 24 by the planetary pinion 20 on it with connect little gear ring 25, connect bull gear 26 cooperating, connect little gear ring 25 to connect with the input end 51 of external hydraulic torque converter of overflow valve 5, the output terminal 52 of external hydraulic torque converter of overflow valve 5 passes the input end 41 of overrunning clutch 4 by the mode of quill shaft, and connect with the input end 41 of overrunning clutch 4 and the planet carrier 29 that confluxes, the output terminal 42 of overrunning clutch 4, fixed carrier 21 and connection planet carrier 24 connect with fixed element, and the planet carrier 29 that confluxes is by the planetary pinion 20 on it and output bull gear 27, conflux gear 28 cooperating, exports bull gear 27 and connect with line of input carrier 33 of confluxing, and line of input of confluxing carrier 33 is by conflux planetary pinion 30 and the output gearwheel 31 on it, conflux input small gear 32 cooperating, exports gearwheel 31 and connect with output shaft 9.
The input power of motor splits into three tunnels through input shaft 1, the first via, flows into input bull gear 23, and flows into the little gear ring 22 of output by the planetary pinion 20 in fixed carrier 21, then flows into by the gear pair 8 that confluxes the input small gear 32 that confluxes; Second tunnel, connects bull gear 26 by secondary 6 inflows of input gear, and flows into the little gear ring 25 of connection by the planetary pinion 20 connected on planet carrier 24, then flow into by external hydraulic torque converter of overflow valve 5 planet carrier 29 that confluxes; 3rd tunnel, flows into by input gear secondary 6 and joining shaft 7 gear 28 that confluxes.
Because the gear 28 that confluxes, the planet carrier 29 that confluxes are the elements that conflux, thus flow into the second tunnel conflux planet carrier 29 power and flow into the 3rd tunnel and to conflux the power of gear 28, conflux in output bull gear 27, then flow into line of input carrier 33 of confluxing.
Due to conflux input small gear 32 and line of input carrier 33 of confluxing are the elements that conflux, so the power flowing into line of input carrier 33 of confluxing confluxes with the inflow first via input the power of small gear 32, conflux in output gearwheel 31, and be delivered to output shaft 9, thus achieve the power of motor is externally exported by output shaft 9.
For the stepless speed variator of composite type hydraulic torque converter with external overflow valve of the present invention, when the rotating speed of input shaft 1 is constant, moment of torsion on output shaft 9 changes with the change of its rotating speed, rotating speed is lower, moment of torsion on output shaft 9 is larger, otherwise, then less, thus realize the present invention can change the composite type hydraulic torque converter with external overflow valve of moment and speed stepless speed variator with the difference of vehicle travel resistance.
When the stepless speed variator of composite type hydraulic torque converter with external overflow valve 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 9 is zero, work as automobile starting, because resistance is larger, and due to the effect of overrunning clutch 4, to conflux planet carrier 29 transfixion, conflux gear 28 being delivered to this moment of torsion by each element 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, be delivered to line of input carrier 33 of confluxing again, and be delivered to the moment of torsion inputting small gear 32 that confluxes and conflux in exporting gearwheel 31, finally be delivered to output shaft 9, 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 29 sense of rotation of confluxing, the input end 51 of external hydraulic torque converter of overflow valve 5 and the speed discrepancy of output terminal 52 constantly reduce, namely the rotating speed of planet carrier 29 of confluxing constantly increases, and converge speed in exporting bull gear 27 with the rotating speed of the gear 28 that confluxes, the rotating speed of output planetary frame 27 is also constantly increased, the rotating speed of line of input of namely confluxing carrier 33 also constantly increases, converge speed in exporting gearwheel 31 and being transferred to output shaft 9 again with the rotating speed inputting small gear 32 that confluxes, thus achieve the power of motor is externally exported by output shaft 9.
