Embodiment
Further specify particular content of the present utility model and working procedure thereof below in conjunction with the accompanying drawing illustrated embodiment.
Consult Fig. 1, Fig. 2, Fig. 3: driving mechanism can be combined by gear and nut-screw, and the gear 21 that is contained on 7 of the drive motor is meshed with gear 23 on being contained in screw rod 4, and nut 5 is contained on the screw rod 4 and limits its rotation, and acceleration cable 6 is fixed thereon.Nut 5 can limit its rotation by anti-turn screw 15.
The displacement transducer that is used to produce signal can be installed in the following ways:
A. direct slide type sensor 28 and Hall sensor 25 can logotypes, slide bar is connected on the mounting plate 8 of drive motor 7 by link arm 29, it can detect the displacement of slide 2 relative guide seats 1, and Hall sensor 25 is placed on the support of drive motor side, and support is fixed on the slide 2.During nut 5 motions, the magnetic field at Hall transducer place changes, and corresponding variation also takes place the voltage signal of the output on the Hall sensor, can judge the position of nut 5 relative slides 2 thus, and in view of the above, computer can accurately be controlled throttle by stepper motor.
B. gliding style sensor 28 is fixed on the sidewall of guide seats 1, and slide bar links to each other with nut 5, can save Hall sensor 25.
C. Hall sensor 25 is fixed on the sidewall of guide seats 1 by its fixing frame 24, and two blocks of magnet 27 are fixed in the magnetic receiver 26, and magnetic receiver 26 is fixed on the side of nut 5.Then the signal of Hall sensor 25 reactions is slide 2 positions on chute, and promptly direct slide type sensor 28 can be saved at this moment in the absolute position of throttle opening.
Driving mechanism can be made up of worm and gear, consults Fig. 4: the worm screw 30 that promptly is contained on the drive motor 7 is matched with turbine 31, and rotational potentiometer 33 and rope sheave 32 are housed on the worm gear wheel shaft, and acceleration cable 6 is fixed on the rope sheave 32.This kind of drive can adopt the direct current generator power source, and direct current generator 36 drives worm screw 30, and worm screw 30 drives Snail wheel 31, and rope sheave 32 is housed on the Snail wheel shaft, and closure stay cord 6 is coupled.Detect the worm gear corner by rotational potentiometer 33.
Consult Fig. 5: can adopt gear 34 on the worm-wheel shaft in the driving mechanism and the tooth bar that is meshed with it 35 replaces rope sheaves 32 acceleration cables 6 and is fixed on the tooth bar 35.
Adopt above-mentioned worm and gear or add pinion and rack, can make the structure of mechanism compact more.Adopt tooth bar can prevent that steel wire tow line from repeatedly bending fatigue damage because of rope-winding wheel.
Positioning work piece 19 can adopt electromagnet or clutch release slave cylinder, clutch release slave cylinder is that oil cylinder or cylinder all can, platen 13 is by on the Title iron of inserting Xiao 12 and being fixed on electromagnet or on the piston rod of clutch release slave cylinder, enter automatic control work condition, computer sends the armature motion of the direct DM of instruction or passes through the piston rod movement of solenoid-driven clutch release slave cylinder, platen 13 is pressed on the sidewall of guide chute, and the position of slide 2 is fixed.Automatically after control work condition finishes, should at first remove the control of positioning work piece, to recover the normal control of foot treadle.The 11st, the positioning work piece motion bar, it can be the piston rod of clutch release slave cylinder or the Title iron of electromagnet.The 20th, be used for the buting iron of restrictor motion bar 11 activities, it can be installed on the slide 2 or on the guide seats 1.
On (ATM) vehicle, during starting, clutch is under computer control, and by the combination of starting rule, simultaneously, stepper motor is controlled oiling automatically by the starting rule; Also can refuel (being accustomed to selecting certain pattern) by driver's step on the gas pedal by the driver.During gearshift, computer at first sends instructions, and throttle is received idling or a certain position, (different gears can be different).After gearshift finished, throttle returned to a certain position, recovered driver's control then.For the Ruiss Controll vehicle, reach the speed of a motor vehicle of a certain anticipation when vehicle after, the driver pulls button, computer is carried out the Ruiss Controll program: detect the speed of a motor vehicle, compare with setting the speed of a motor vehicle, when being lower than a certain specified value, the forward or reverse stepper motor, after reaching setting value, stepper motor quits work, near vehicle travel a certain setting speed of a motor vehicle (wave range is by the decision of the given precision of program).For the vehicle of tractive force control, this throttle actuator can carry out various accurate controls according to the control model.As: automobile is being started to walk, is being stepped on too quicklyly as if accelerator pedal when quickening, can occur the situation that driving wheel is trackslipped because driving force is excessive, at this moment computer in time sends instruction according to the situation of trackslipping, and the control step motor reduces throttle, reduce engine power output, suppress trackslipping of driving wheel.On the vehicle that traction control system is housed of new production, general motor all has main, pair two closures.One of them closure aims at regulates engine power output usefulness.And the actuator of this throttle on the motor of a closure, both can realize accurate power output control, and this installs tractive force control additional to the vehicle of having produced that does not have traction control system convenience is provided.
The Throttle Opening Control of Ruiss Controll vehicle.The characteristics of vehicle cruise control are that the speed of a motor vehicle remains unchanged.This is at automatic speed changing (AMT) vehicle that above-mentioned Throttle Opening Control mechanism is housed and be equipped with on the vehicle of tractive force control (TRC), both can realize as long as increase a part of software Ruiss Controll program.Computer is gathered current vehicle speed and the given speed of a motor vehicle relatively, if little (greatly) arrives certain certain value, then sends instructions, and allows just (instead) commentaries on classics of stepping motor, and the speed of a motor vehicle is stabilized on the constant substantially given numerical value.If common vehicle then will be mixed computer and this throttle actuator.
The oiling throttle actuator of motor.With manual operating closure control engine speed.Both controlled difficulty, again waste of manpower.Use this throttle actuator, can realize manually, jointly control automatically.Pulling handcontrolled manipulation bar to a certain rotating speed, unclamps the operating handle button with the engine speed coarse adjustment, and operating handle is parked in this position (being equivalent to positioning work piece 19 in the actuator).After this can be as Ruiss Controll, engine speed can always work in (error can be very little) on the given rotating speed.Also can push control knob by slowly (or fast) increase (reducing) of rotating speed.Also can reserve normal revolution in advance, push corresponding control knob, can operate in automatically on this rotating speed.
Simple and easy Ruiss Controll.On expressway, the road traveling change in resistance is little.Certain accelerator open degree, corresponding basically certain speed of a motor vehicle.In mechanism shown in Fig. 1-3, on slide, only keep positioning work piece, other parts all save.At this moment, the power section among the former figure, do-part is born by driver's pin.Driver's control (having saved computer in this mechanism) is placed on the circuit switch in the operator cabin, and when vehicle driving arrived certain vehicle speed, the driver can move switch by plate, positioning work piece 19 work, and throttle is fixed, and vehicle operation is on this " cruises " speed of a motor vehicle.If wanting increases (reduction) speed of a motor vehicle, Buck Plate moves switch, and positioning work piece 19 unclamps, and throttle is by pilot control.This is simple in structure, practical, and cost is low.
