Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the automatic/hand stepless speed variator, mainly comprise: shell 26, setting driving shaft 1, driven shaft 6, speed change gear group, gear ring 25, centrifuge 10, hydraulic-pressure pump 11, oil hydraulic motor 12, hydraulic control valve rod 20 and hydraulic control valve 19 in the enclosure, speed change gear group, gear ring 25 and driving shaft pinion 3 are installed on driving shaft 1, driving shaft is connected with driven shaft 6, driven shaft is provided with the planetary carrier 4 that is fixed with one with it, and the suit section of driven shaft and driving shaft is equipped with needle bearing 15.Be shaped on gear ring internal gear 7 on the circle in the described gear ring, be shaped on gear ring external gear 8 on the cylindrical.The speed change gear group comprises: be installed in driving shaft master gear 2 and planetary pinion 5 engagements on the driving shaft 1, planetary pinion engagement gear ring internal gear 7, described planetary pinion 5 is at least three, and the planetary pinion in the present embodiment is designed to four, and is installed in the gear ring 25 by planetary carrier 4.Also be set with centrifuge 10 on the driving shaft of driving shaft pinion one side, described clutch be by be packed in square position 10-2 on the driving shaft, can along the axially movable conical disc 10-1 of driving shaft and be arranged on conical disc and the square position between steel ball 9 constitute.Be provided with spring 16 between centrifuge and the driving shaft pinion, centrifuge conical disc front side is connected with hydraulic control valve rod 20, the hydraulic control valve rod connects hydraulic control valve 19, and the solenoid valve pull bar 18 in hydraulic control valve rod underpart by perpendicular connection is equipped with solenoid valve 17.Driving shaft pinion engagement oil hydraulic pump gear 13, gear ring external gear engagement oil hydraulic motor gear 14, oil pipe 21 connects hydraulic-pressure pump 11 filler openings, oil pipe 22 1 ends connect the hydraulic-pressure pump oil outlet, the other end connects hydraulic control valve, and oil pipe 23 1 ends connect hydraulic control valve 19, and the other end connects the filler opening of oil hydraulic motor, oil pipe 24 1 ends connect the oil outlet of oil hydraulic motor, and the other end connects hydraulic control valve.
Working principle of the present utility model is: with the electronic or combustion engine powered driving shaft 1 that is transferred to, driving shaft rotates by the planetary pinion 5 that driving shaft pinion 2 drives on the driven shaft 6, gear ring external gear 8 is engaged on the oil hydraulic motor gear 14 of oil hydraulic motor 12, oil hydraulic motor is under the control of hydraulic control valve 19, close the path of hydraulic oil pipe 24, played braking action, at this moment gear ring 25 does not rotate.When driving shaft forwards 1500 commentaries on classics to (rotating speed can be decided according to demand), steel ball 9 is under action of centrifugal force, outwards throw away, when steel ball is outwards thrown away, can promote the conical disc 10-1 of centrifuge, conical disc is slided to the driven shaft direction on driving shaft, thereby promote hydraulic control valve rod 20, make hydraulic control valve 19 open the path of hydraulic oil pipe 22,23 and 24.Hydraulic-pressure pump 11 is by the connection of hydraulic oil pipe 22 and 23, oil hydraulic motor is rotated, drive gear ring external gear 8 by oil hydraulic motor gear 14 again, the same direction of gear ring 25 and driving shaft is rotated, this moment is because the rotation of gear ring, when driving shaft keeps original rotating speed, also can accelerate the rotating speed of driven shaft, thereby make the electrodeless acceleration of driven shaft energy.The driving shaft rotating speed is high more, and the centrifugal force of steel ball is also big more, therefore hydraulic control valve rod 20 has been produced bigger Driving force, the flow of hydraulic control valve 19 is increased, the rotating speed of oil hydraulic motor is improved, and output speed also improves thereupon, to realize its stepless change.When driving shaft decelerates to 1500 when changeing following, the centrifugal force of steel ball 9 reduces, under the effect of spring 16, with the conical disc 10-1 pushed home of centrifuge.When Motor Vehicle goes up a slope, can open solenoid valve 17, by solenoid valve pulling hydraulic control valve rod 20, make steel ball 9 centrifugal force can't promote the centrifuge conical disc, and can't give driven shaft 6 stepless acceleration, make motor drive the corresponding raising of speed drive shaft, and can be transferred to the bigger moment of torsion of driven shaft.When the Motor Vehicle descending, the working principle when going up a slope by Motor Vehicle, Motor Vehicle need not to step on braking, can make the very fast deceleration of Motor Vehicle.When needs adopt manual stepless change, centrifuge on this speed changer 10 and solenoid valve 17 can be removed, by manually controlling hydraulic control valve rod 20, realize the manual control of hydraulic control valve 19 again.
