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 centripetal turbine type hydraulic torque converter, comprises input shaft 1, conflux gear pair 4, output gear wheel set 5, overrunning clutch 6, centripetal turbine formula fluid torque converter 7, input gear pair 8, output shaft 9, is provided with planetary pinion 20 between described input shaft 1 and output shaft 9, fixed carrier 21, input bull gear 22, output pinion 23, connect output gear 24, connect bull gear 25, connect line of input carrier 26, conflux planet carrier 27, conflux gear ring 28, conflux output gear 29, conflux planetary pinion 30, conflux little gear ring 31, conflux bull gear 32, conflux output planetary frame 33, and the input gear 81 of input bull gear 22 and input gear pair 8 connects with input shaft 1, and line of input carrier 21 is by the planetary pinion 20 on it and input bull gear 22, output pinion 23 cooperating, output pinion 23 connects with the planet carrier 27 that confluxes, the output gear 82 of input gear pair 8 connects with the input end 71 of the input gear 41 of the gear pair 4 that confluxes and centripetal turbine formula fluid torque converter 7, the output gear 42 of gear pair 4 of confluxing connects with the bull gear 32 that confluxes, the output terminal 72 of centripetal turbine formula fluid torque converter 7 passes the input end 61 of overrunning clutch 6 by the mode of quill shaft, and connect with the input end 61 of overrunning clutch 6 and the input gear 51 of output gear wheel set 5, the output terminal 62 of overrunning clutch 6, fixed carrier 21 and connect bull gear 25 and connects with fixed element, the output gear 52 of output gear wheel set 5 with connect line of input carrier 26 and connect, connection line of input carrier 26 is passed through planetary pinion 20 on it and is connected output gear 24, connect bull gear 25 cooperating, connect output gear 24 and connect with the gear ring 28 that confluxes, the planet carrier 27 that confluxes is by the planetary pinion 20 on it and the gear ring 28 that confluxes, conflux output gear 29 cooperating, and the output gear 29 that confluxes connects with the little gear ring 31 that confluxes, and the output planetary frame 33 that confluxes is by conflux planetary pinion 30 and the little gear ring 31 that confluxes on it, conflux bull gear 32 cooperating, and the output planetary frame 33 that confluxes connects 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 22, and flows into output pinion 23 by the planetary pinion 20 in fixed carrier 21, then flow into the planet carrier 27 that confluxes; Second tunnel, flows into centripetal turbine formula fluid torque converter 7 by input gear secondary 8, then connects line of input carrier 26 by output gear wheel set 5 inflow, connects line of input carrier 26 and flows into connection output gear 24 by the planetary pinion 20 on it, then flow into the gear ring 28 that confluxes; 3rd tunnel, flows into by input gear secondary 8 gear pair 4 that confluxes, then flows into the bull gear 32 that confluxes.
Because the planet carrier 27 that confluxes, the gear ring 28 that confluxes are the elements that conflux, thus flow into the first via conflux planet carrier 27 power and flow into the second tunnel and to conflux the power of gear ring 28, conflux in the output gear 29 that confluxes, then flow into the little gear ring 31 that confluxes.
Owing to confluxing, little gear ring 31 and the bull gear 32 that confluxes are the elements that conflux, so flow into the power of the little gear ring 31 that confluxes and flow into the 3rd tunnel and to conflux the power of bull gear 32, conflux in the output planetary frame 33 that confluxes, 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 centripetal turbine type hydraulic torque converter 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 centripetal turbine type hydraulic torque converter of moment and speed stepless speed variator with the difference of vehicle travel resistance.
