Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullSuch as Fig. 1、Fig. 2、Fig. 3、Shown in Fig. 4 and Fig. 5，This utility model provides electronic throttle，Including throttle body 1，The air throttle valve block 2 being arranged on throttle body 1 and the valve rod 3 being connected with air throttle valve block 2，It is characterized in that: also include reluctance machine 4、Control unit 5、The control circuit 6 being connected with control unit 5 and jaw opening sensor 7，The output shaft of described reluctance machine 4 connects reduction gearing，Described reduction gearing includes gear wheel 8 and little gear 9，The output shaft of described reluctance machine engages with gear wheel 8，One end of described valve rod 3 is fixedly connected with sector gear 11，Described little gear engages with sector gear，Described sector gear is also associated with back-moving spring 10，Described throttle body also includes base plate 12 and the cover plate 13 being fixedly installed in the way of detachable on base plate 12，Described control circuit and jaw opening sensor are arranged between base plate and cover plate.
As this utility model specific embodiment, one end 101 of described back-moving spring is fixedly mounted on described air throttle housing 1, the other end 102 is fixedly mounted on sector gear, and described air throttle housing is additionally provided with first boss 14 and second boss 15 corresponding with sector gear.Described reluctance machine includes stator 42, be wound on stator 42 coil 41 and the rotor 43 being arranged on stator, described rotor is connected with the output shaft of reluctance machine.
Owing to the rotational angle of switching motion of air throttle valve block is only in the range of 90 degree, the gear on described throttle plate pin has only to be arranged to the gear of arc can meet demand, is also beneficial to reduction processing cost.The deceleration device band moving valve plate that is rotated through of rotor rotates, it is achieved the opening and closing function of reluctance type electronic throttle.
During reluctance type electronic throttle efforts, when not giving the coil power supply of reluctance machine, whole motor is without magnetic field, valve block is pulled to initial position by the prefastening force of back-moving spring, valve block now is in fully open position, when to the coil electricity of reluctance machine, reluctance machine just produces twisted magnetic field force, now the torsional moment of rotor is maximum, the pulling force of back-moving spring is minimum, therefore rotor starts to rotate, producing magnetic field in stator makes rotor valve rod and valve block rotate, deflection along with rotor, reluctance machine torsional moment is more and more less, the pulling force of back-moving spring is increasing, when the pulling force of reluctance machine torsional moment and back-moving spring is equal in magnitude, rotor stress reaches balance, it is not rotated further by, realize the closing function of air throttle.
When reducing the supply current of reluctance machine, the torsional moment of reluctance machine synchronizes to reduce, and rotor, valve rod and valve block invert under the pulling force effect of back-moving spring, thus plays the effect controlling reluctance type electronic throttle aperture.When the supply current of reluctance machine is in a certain fixed value, the torsional moment of reluctance machine is equal with the pulling force of back-moving spring, i.e. rotor and back-moving spring reaches balance, again so that reluctance type electronic throttle is stably in a certain new aperture；I.e. achieve the Linear Control of reluctance type electronic throttle.
One end of described back-moving spring is fixedly mounted on described air throttle housing, the other end is fixedly mounted on sector gear, first boss corresponding with sector gear and the second boss it is additionally provided with on described air throttle housing, when valve block full-gear, sector gear one end contacts with the first boss, i.e. first boss limits the rotation of sector gear, when when valve block full closing state, sector gear one end contacts with the second boss, i.e. second boss limits the rotation of sector gear, i.e. first boss and the second boss serve spacing effect to sector gear, prevent making valve block rotate because of fault abnormal.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
