Embodiment
Working principle of the present invention is as shown in Figure 1, and dotted portion is magnetorheological control gear, and epicyclic transmission mechanism adopts the mode of differential planet gear series connection.The sun gear b1 that driving shaft a1 drives first order planetary differential train rotates; When magnetic flow liquid solidifies; Power passes to driven shaft a2 through magnetic flow liquid; Driven shaft a2 links to each other with the gear ring b3 of first order planetary differential train, thereby transmission of power is given first order planetary differential train, realizes differential input.The planet carrier b4 of first order planetary differential train links to each other with the sun gear c1 of second level planetary gear train, thereby the planet wheel b2 of first order planetary differential train gives second level planetary gear train through planet carrier b4 with transmission of power.The gear ring c3 of second level planetary gear train is fixed on the frame planet carrier c4 output of final power via second level planetary gear train.
Shown in accompanying drawing 2, the present invention can be by motor driving, and the epicyclic transmission mechanism among the present invention adopts the mode of differential planet gear series connection, and the transmission of its power is through two approach.First via power is by 11 rotations of driven by motor driving shaft, and driving shaft 11 is provided with friction plate 15 in several, and the distance between the interior friction plate 15 is confirmed by interior retainer 14; Because interior friction plate 15 is fixed on the driving shaft 11, so when driving shaft 11 rotations, the and then rotation of interior friction plate 15; When field coil 6 energisings, magnetic flow liquid 10 begins to solidify, and interior friction plate 15 is given outside friction disc 9 transmission of torque through magnetic flow liquid 10; Outside friction disc 9 cooperates with interior friction plate 15 at interval; The distance of outside friction disc 9 confirms that by outer retainer 8 outside friction disc 9 all is fixed on the driven shaft 16 with outer retainer 8, thereby driven shaft 16 begins rotation and output torque.The ring gear 3 of driven shaft 16 and first order planetary differential train is connected through screw, and transmission of power is given first order planetary differential train, and when magnetic flow liquid solidified fully, interior outside friction disc rotating speed equated.After the second road power passes to input shaft 11 by motor; Input shaft 11 is the central gear of first order differential planetary train simultaneously, through with the differential output of ring gear 3, rotate thereby drive planet wheel 18; Planet wheel 18 links to each other through key 26 with coupling shaft 27; Thereby transmission of power is given coupling shaft 28, and coupling shaft 27 also is the sun gear of second level planetary gear train simultaneously, and gear ring 20 is fixed on the frame; Thereby planet wheel 21 begins to rotate and give output shaft 25 through planet carrier 22 with transmission of power, thereby finally by output shaft 25 output torque drive load runnings.
When motor just brings into operation; Magnetic flow liquid under the no impressed current shows as the characteristic of fluid; Rotating speed that magnetorheological control gear is exported and torque nearly all are zero, have only central gear 11 input speeds and the torque of first order differential gear train in the mechanism, and the output shaft 25 of this moment is not exported torque; When field coil 6 energisings, this moment, magnetic field was added on the magnetic flow liquid, and magnetic flow liquid begins to solidify; Magnetorheological control gear work, and beginning output speed and torque, this moment, the power input of mechanism was divided into magnetorheological control gear and motor two-way; It is big that the rotating speed of load begins to become; When magnetic flow liquid solidifies fully, load speed is a maximum value, accomplishes the one-shot process.The electric current of field coil is big more; The magnetic field that produces is also big more, thereby the shearing stress of magnetic flow liquid is also big more, one timing in magnetic field simultaneously; The slippage (speed discrepancy between rotating plate and the driven plate) that acts on the magnetic flow liquid is big more, and the shearing stress of magnetic flow liquid is also big more.Therefore can adopt the control coil method of current, the shearing stress of control magnetic flow liquid, slippage capable of using carries out speed governing simultaneously; Concrete grammar is: as it is excessive to go out rotating speed, can be through turning coil current down, thus make the slippage of magnetic flow liquid become big; Thereby make output speed reduce; Otherwise then increase coil current, thereby make the output torque of device make it to adapt, and obtain corresponding rotating speeds with this with load.
The present invention is combination like this: left casing 2, and right casing 28, fixed frame 19 is formed the housing of whole device; Driving shaft 11 links to each other with interior friction plate 15 through key, and the distance between the interior friction plate 15 confirms through interior retainer 14 and carry out axially locating by it that distance between outside friction disc 9 is confirmed through outer retainer 8 and carried out axially locating by it; Driven shaft 16 and exhausted magnet ring 7 are connected through bolt, and they constitute the cavity of whole magnetic flow liquid control gear 5, and magnet ring 7 is through being bolted on the driven shaft 16 extremely; The cavity that between the interior outside friction disc is magnetorheological control gear is full of magnetic flow liquid 10, and coil 6 is in left casing 2, and coil 6 lead-in wires are drawn through conduit 17; Magnetic flow liquid 10 is through felt ring seal, and the ring gear of driven shaft 16 and first order planetary differential train 3 is connected through bolt, and driving shaft 11 also is the sun gear of first order differential planetary gear train simultaneously; Ring gear 3; Planet wheel 18, planet carrier 4, driving shaft 11 have constituted first order planetary differential train; Thereby realize differential input, the planet carrier 4 of first order differential planetary gear train links to each other with coupling shaft 27 through key 26; Planet carrier 22, coupling shaft 27; Planet wheel 21 has constituted second level planetary gear train with gear ring 20; Gear ring 20 is through being bolted on the casing; Planet carrier 22 through bearings on right casing 28, planet carrier 22 right half of make an integral body with output shaft 25 and by bearings on right casing 28.
Magnetorheological hydraulic control transmission device controlling method is as shown in Figure 3; The size of coming real-time monitoring load torque T by torque transducer TB1A/100 and supporting with it MP55 power amplifier; Through the AD conversion, the analog signal conversion that MP55 is exported becomes digital signal, and is transferred to single-chip microcomputer; Single-chip microcomputer judges whether magnetorheological hydraulic control transmission device output torque can be complementary with the required torque of load and by the output current I size of Single-chip Controlling power supply; Thereby change the size in the magnetic field of field coil, thereby change the size of magnetic flow liquid shearing force, thereby change the output torque of magnetorheological hydraulic control transmission device.When load torque became big, torque transducer detected signal, and was transferred to single-chip microcomputer; The Single-chip Controlling controllable electric power makes source current I become big, thereby makes the output torque become big; Otherwise when diminishing as if load torque, Single-chip Controlling electric power outputting current I diminishes, thereby makes the output torque diminish; Make the output torque and the load torque of magnetorheological hydraulic control transmission device adapt with this, and obtain corresponding rotating speeds with this.
