Embodiment
Below in conjunction with accompanying drawing, the present invention is explained in detail:
This clutch actuating mechanism is followed successively by the baffle plate 11 of brshless DC motor 1, clutch play automatic regulating apparatus, ball-screw nut, displacement transducer 6, pull bar 8, self-locking device, outputting power from left to right.The clutch play regulating device comprises adjusts cylinder 20, the serrate adjustment block 3 of marginal zone, adjustment plate 21, adjustment spring 4, balance spring 2.Self-locking device comprises overrunning clutch 9, compact heap 16, holddown spring 15, housing screw 14, locking nut 13.
Screw rod 7 one ends of ball screw are connected with the projection of motor by groove through the clutch play regulating device, and the other end is connected with ring 25 in overrunning clutch in self-locking device by free-sliding spline.External Ring of One-way Clutch 26 is fixed on clutch actuating mechanism shell 10 bottoms under the impacting force effect of housing screw 14, holddown spring 15 and compact heap 16.
The adjustment plate 21 of clutch play regulating device is arranged on the screw rod 7 of ball screw by angular contact bearing a19 and angular contact bearing b23.Be with serrate adjustment block 3 to be positioned at adjustment plate 21 inside, and the trend that has radially outward to move under the effect of adjusting spring 4 elastic force, thus with actuator shell 10 inwalls on the interlock of tooth phase.Adjusting cylinder 20 is inserted in vertically in adjustment plate 21 and passes adjustment block 3.Adjust on cylinder 20 and be processed with inclined-plane, fit with the inclined-plane on adjustment block 3.Adjust cylinder 20 deeply interior when mobile to adjustment plate 21, can adjustment block 3 radially be moved inward by inclined-plane, thereby remove the interlock with actuator's shell 10 inwalls.
The duty cycle signals that this electric clutch actuator controls with PWM by the motor sense of rotation that receives motor-drive circuit output reaches controls the purpose that automobile clutch separates joint, and carries out feedback control by displacement transducer.Can sum up electric clutch actuator for this reason and receive the expectation displacement signal of clutch control, and be realized.Can when the motor no signal is inputted, be parked in reliably for a long time random desired location by self-locking device, saving power, simplify and control, and improves electrical machinery life.Gap adjusts automatic engagement positions at capable of automatic regulating gap after the clutch friction pad wear, to guarantee that automobile clutch still can engage fully after friction disc wear simultaneously.
Working procedure of the present invention is motor 1 rotation, the groove structure of the projection by motor 1 and the screw rod 7 of ball screw drives screw rod 7 rotations of ball screw, the nut 18 of ball screw is driven by widening the pull bar 8 that part 17 is fixedly connected with and do axial-movement, press again the withdrawal fork of automobile clutch by baffle plate 11 drivening rod mechanisms, automobile clutch is separated or combination.The present invention adopts brshless DC motor, and the servo-system be comprised of brushless direct current motor has the advantages that torque is level and smooth, response is fast, control accuracy is high, therefore be applicable to the good power source of clutch actuating mechanism.This kind of motor both had the characteristics that AC motor structure is simple, reliable, maintenance workload is little, had again the control performance same good with direct current motor.Adopt the high ball screw of transmission efficiency can improve the speed of response of system as transmission device, promote the dynamic performance of car load.
Another aspect of the present invention relates to the self-locking device of automatic clutch actuator.
Due to reasons in structure, the transmission efficiency of ball-screw nut is very high, but also has very high reverse efficiency simultaneously, when having axial force to be applied on the nut 18 of ball screw, the screw rod 7 of ball screw can rotate, the nut 18 of ball screw can axially move, if want to allow automobile clutch remain on for a long time a certain position, the voltage at motor two ends just can not be interrupted, now motor speed is zero, can waste electric energy like this, shorten electrical machinery life, also be unfavorable for the control of clutch.
In order to address this problem, at ball screw, away from motor 1 one ends, install an overrunning clutch 9 and a set of adjusting hold down gag (compact heap 16, holddown spring 15, housing screw 14, locking nut 13) additional.It is very high that overrunning clutch 9 is rotated in the forward efficiency, but ring 25 relative External Ring of One-way Clutch 26 lockings in overrunning clutch during reverse rotation.Regulating the hold down gag working principle is that housing screw 14 presses holddown spring 15, then presses compact heap 16, finally compresses External Ring of One-way Clutch 26.Housing screw 14 is locked by locking nut 13 after mixing up impacting force.
The screw rod 7 of ball screw is connected by free-sliding spline with ring 25 in overrunning clutch, and External Ring of One-way Clutch 26 is arranged in clutch actuating mechanism shell 10, by the compact heap 16 of regulating in hold down gag, compresses.The screw rod 7 that drives ball screw when motor 1 is rotated in the forward is rotated in the forward, in the overrunning clutch that screw rod 7 tail ends of ball screw connect by free-sliding spline, ring 25 also efficiently is rotated in the forward, External Ring of One-way Clutch 26 is motionless, the nut 18 of ball screw drives widens part 17, drive again pull bar 8 promotion baffle plates 11 and travel forward, drive corresponding linkage mechanism propelling vehicle clutch and separate rapidly.Because the External Ring of One-way Clutch of installing in the present invention 26 is subject to the impacting force effect of hold-down mechanism, when motor 1 no signal input, under the effect of Automobile Clutch Plate Spring restoring force, the screw rod 7 of ball screw has the trend of reversion, now in overrunning clutch, encircle 25 with respect to External Ring of One-way Clutch 26 lockings, but the moment of torsion that the restoring force that only relies on Automobile Clutch Plate Spring converts to can't overcome the moment of torsion that the impacting force of hold down gag generation generates, so now clutch actuating mechanism can in the situation that motor 1 not have signal input to remain on any given position motionless, reach the purpose of self-locking.
When the needs automobile clutch in conjunction with the time, motor 1 counterrotating, overcome the moment of torsion of the impacting force generation of hold-down mechanism under the moment of torsion acting in conjunction of the restoring force conversion of the moment of torsion produced at motor 1 and Automobile Clutch Plate Spring, guarantee that automobile clutch can be with the steady combination of arbitrary speed, the moment of torsion that the moment of torsion that motor 1 counterrotating produces converts to the Automobile Clutch Plate Spring restoring force is the same, be a part that drives the moment of torsion of External Ring of One-way Clutch 26 overcome friction rotations, can not produce the phenomenon of shake.
The invention still further relates to Friction Facing on Clutch Disc in Heavy wearing and tearing gap automatic regulating device afterwards.
Automobile running is after a period of time, Friction Facing on Clutch Disc in Heavy will produce certain wearing and tearing, the distortion after clutch engages fully of diaphragm spring in automobile clutch can strengthen, for push type clutch actuator, require the pull bar 8 of clutch actuating mechanism after the Friction Facing on Clutch Disc in Heavy wearing and tearing to move a certain distance backward on original base, guarantee that automobile clutch still can engage fully.
Pull bar 8 of the present invention is fastenedly connected by widening part 17 with the nut 18 of ball screw, and the position ball-screw nut engaged fully at automobile clutch suspends together with pull bar 8.Automobile clutch can be adjusted ball-screw nut and pull bar 8 initial positions automatically according to concrete abrasion condition after engaging.
For reaching this purpose, the present invention has designed a set of gap automatic regulating device.Gap automatic regulating device comprises adjusts cylinder 20, the serrate adjustment block 3 of marginal zone, and adjustment plate 21, adjust spring 4, balance spring 2.The screw rod 7 of ball screw, is connected with motor 1 by groove through adjustment plate 21 near motor one end.The groove of the screw rod 7 of ball screw and the projection of motor can axially relatively move a segment distance and not affect the transmission of rotation.An end away from motor of the screw rod 7 of ball screw is connected with ring 25 in overrunning clutch by free-sliding spline, also can move axially a segment distance and not affect the transmission of rotating relative to overrunning clutch.This two segment distance is the clutch play adjustment amount.A balance spring 2 is installed between adjustment plate 21 and motor 1.By two symmetrical angular contact bearing a19 and angular contact bearing b23 that install, adjustment plate 21 is connected on the screw rod 7 of ball screw, makes the adjustment plate 21 can the tension pressurized with respect to the screw rod 7 of ball screw.The shaft shoulder of the screw rod 7 by ball screw and jump ring 24 diametrical connection contact bearing a19 and angular contact bearing b23 position, and the screw rod 7 of adjustment plate 21 relative ball screws can't be axially moved, but the screw rod 7 of ball screw can rotate relative to adjustment plate 21.Adjustment block 3 has four, and symmetry is arranged in the groove of adjustment plate 21, and root inserts adjusts cylinder 20, and adjusting cylinder 20 and adjustment block 3 has the inclined-plane cooperatively interacted.The spring 4 of adjustment is arranged between adjustment block 3 and adjustment plate 21.There is sawtooth at adjustment block 3 edges, adjusting, spring 4 effect downward full circle posts 20 are axially outwards outstanding, adjustment block 3 radially outwards are outstanding, make in the automobile clutch separation process and pass through the sawtooth interlock with the inwall of clutch actuating mechanism shell 10 always, axially can't move.
Gap is automatically adjusted and is occurred in motor 1 counterrotating until automobile clutch when entering full jointing state.When Automotive Clutch Engagement closes to an end, the nut 18 on ball screw will press adjustment cylinder 20 outstanding on adjustment plate 21.Adjusting cylinder 20 middle parts has skewed slot, is pressed rear drive adjustment block 3 to central motion, and adjustment block 3 is to separating with the tooth of actuator shell 10 inwall interlocks after central motion.Lash adjusting device, ball-screw nut together with pull bar 8 in state of suspension.
If now not wearing and tearing of Friction Facing on Clutch Disc in Heavy, under the effect of balance spring 2, adjustment plate 21, it is motionless that ball-screw nut remains on original position together with pull bar 8.If Friction Facing on Clutch Disc in Heavy has certain wearing and tearing, after automobile clutch engages, the automobile diaphragm spring finger tip still has axial force, and pull bar will have certain load.Therefore after Friction Facing on Clutch Disc in Heavy has certain wearing and tearing, when adjustment block 3 is separated with the tooth of actuator shell 10 inwall interlocks, ball-screw nut together with pull bar 8 when the state of suspension, adjustment plate 21, ball-screw nut is whole to close motor one side shifting under the effect of this load together with pull bar 8.After load and balance spring 2 re-establish balance, ball-screw nut is parked in new equilibrium position again together with pull bar 8 adjustment plates 21.Motor is rotated in the forward, and the nut 18 of ball screw separates with adjustment plate 21.Come back to original position in pressure-acting downward full circle post 20 and the adjustment block 3 of adjusting spring 4, the edge of adjustment block 3 and actuator's shell 10 inwalls are engaged in new position by sawtooth again, reach the clutch abrasion self-adjusting purpose in gap afterwards.
Lower mask body is introduced automatic clutch actuator controlled clutch of the present invention and is separated the overall process engaged.
At first, automobile clutch is in complete jointing state, and the position of nut 18 in the most close motor 1 one ends of ball screw, be designated as dead-center position.The screw rod 7 of ball screw is connected with ring 25 in overrunning clutch by free-sliding spline away from motor 1 one ends.It is very high that the interior ring 25 of overrunning clutch is rotated in the forward efficiency with respect to External Ring of One-way Clutch 26, reverse locking.Motor 1 is rotated in the forward the screw rod 7 that drives ball screw and is rotated in the forward, nut 18 travels forward, and with nut 18, by the pull bar 8 of widening part 17 and being fastenedly connected, travels forward, and promotes baffle plate 11, baffle plate 11 promotes linkage mechanism propelling vehicle clutch release fork, the quick and complete separation of automobile clutch.Because for the control of automobile clutch, require the automobile clutch separation process quick, thoroughly.So it is very rapid that whole process is carried out.
The automobile clutch after separating, when motor 1 does not have signal when input, under the effect of automobile diaphragm spring restoring force, have pull bar 8 rollback backward that makes clutch actuating mechanism, nut 18 rollbacks of ball screw, the trend of screw rod 7 counterrotatings of ball screw.But the screw rod of ball screw 7 is connected with ring 25 in overrunning clutch by free-sliding spline away from motor 1 one ends, locking when in overrunning clutch, ring 25 is with respect to External Ring of One-way Clutch 26 counterrotating, and outer shroud compresses by hold down gag, now the moment of torsion of the screw rod 7 of ball screw is not enough to overcome the moment of torsion that frictional force that hold down gag produces converts to, so when the automobile clutch after separating, when motor does not have the signal input, automobile clutch can reliably rest on any position.
When the needs automobile clutch engages, motor 1 counterrotating, drive screw rod 7 counterrotatings of ball screw, now the moment of torsion of motor 1 adds that moment of torsion that Automobile Clutch Plate Spring converts to is enough to overcome the moment of torsion that frictional force that External Ring of One-way Clutch 26 produces by hold-down mechanism converts to, automobile clutch just can be smooth-going like this, with arbitrary speed, engages.
The screw rod 7 of ball screw is stuck on the adjustment plate 21 in gap automatic regulating device by two symmetrical angular contact bearing a19 and angular contact bearing b23 that install near motor 1 one ends, can't do relative motion.A balance spring 2 is arranged between adjustment plate 21 and motor 1.There is outstanding adjustment block 3 at adjustment plate 21 edges, and the spring 4 of adjustment is arranged between adjustment block 3 and adjustment plate 21, and there is sawtooth at the edge of adjustment block 3, with the sawtooth phase interlock of clutch actuating mechanism shell 10 inwalls.Clutch actuating mechanism suffered axial force all by these sawtooth, born.When returning back to the dead-center position with respect to screw rod 7, the nut 18 of ball screw will press the adjustment cylinder 20 be inserted between adjustment plate 21 and adjustment block 3.Adjust between cylinder 20 and adjustment block 3 and coordinates by inclined-plane, after adjusting cylinder 20 and being depressed, the power that adjustment block 3 overcomes adjustment spring 4 is driven, to adjustment plate 21 central motions, regulating device now, ball-screw nut together with pull bar 8 in state of suspension.If Friction Facing on Clutch Disc in Heavy is wearing and tearing not, the nut 18 of ball screw is when dead-center position, and automobile clutch engages fully, and now clutch actuating mechanism will can not be subject to the effect of axial force.Regulating device, ball-screw nut will still be in original position after suspending together with pull bar 8 under the effect of balance spring 2, not change.If Friction Facing on Clutch Disc in Heavy has certain wearing and tearing, the nut 18 of ball screw is when dead-center position, automobile clutch does not engage fully, now clutch actuating mechanism will still be subject to the effect of axial force, regulating device, ball-screw nut retreats together with pull bar 8, rests on new equilibrium position after re-establishing balance with balance spring 2.The nut 18 that motor 1 is rotated in the forward ball screw again separates with adjustment plate 21, now adjusting cylinder 20 ejects, the be adjusted effect of spring 4 of adjustment block 3 is outwards pushed, with actuator shell 10 interlocks, (Friction Facing on Clutch Disc in Heavy not wearing and tearing is engaged in origin-location again, be engaged in new position after wearing and tearing), bear automobile clutch and separate the axial force produced.
