Wherein: the hole on 1-throttle body, 2-closure valve rod, 3-valve block, 4-reluctance machine, 5-rotor, 6-stator, 7-coil, 8-limiting board, 9-torsion spring, 10-throttle body, the hole on 11-limiting board.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
The structure of magnetoresistive type electronic throttle as shown in Figure 1, comprise the throttle body 1 being provided with gas channel, be provided with the closure valve rod 2 in uprush direction in the gas channel of throttle body 1, closure valve rod 2 be fixedly installed the valve block 3 controlling gas channel and open and close.The outer wall of throttle body 1 is arranged a reluctance machine 4, the top of the output shaft connecting joint valve stem 2 of reluctance machine 4; The bottom of closure valve rod 2 stretches out that throttle body 1 is outer and by being arranged on throttle body 1 Outer Bottom Plating location, base plate is connected by bearing with closure valve rod 2 bottom.
The bottom outer cover that closure valve rod 2 stretches out throttle body 1 is equipped with sleeve, and sleeve, between throttle body 1 and base plate, base plate is also provided with the limiting board 8 be slidably matched with base plate, and limiting board is fixedly connected with closure valve rod bottom.Being provided with torsion spring 9 between limiting board 8 and sleeve, resetting for making valve block 3; One end of torsion spring 9 is arranged in the hole 10 on throttle body, and the other end is arranged in the hole 11 on limiting board, and valve block 3 is pulled to fully open position by torsion spring 9 return pulling force.
Reluctance machine 4 comprises shell and is positioned at the ring type stator 6 of shell, is wound on coil 7 on rotor and the rotor 5 being arranged on side corresponding with coil on rotor, as shown in Figure 2; Rotor 5 is connected with closure valve rod 2 top.The rotation of rotor 5 is with moving valve plate 3 to rotate by valve rod 2, realizes the opening and closing function of magnetoresistive type electronic throttle.
In magnetoresistive type electronic throttle working procedure, when powering to the coil 7 of reluctance machine 4, whole motor is without magnetic field, and rotor 5 is pulled to as Fig. 1 position by torsion spring 9 pretightening force, and now valve block 3 is in fully open position.
Be energized to the coil 7 of reluctance machine 4, reluctance machine just produces twisted magnetic field force, and now the torsional moment of rotor is maximum, and the torsional moment of torsion spring is minimum, therefore rotor starts to rotate, and produces magnetic field rotor 5, valve rod 2 and valve block 3 are rotated in stator 6; Along with the deflection of rotor, reluctance machine torsional moment is more and more less, and the torsional moment of torsion spring is increasing, and when two moment equal and opposite in directions, rotor is stressed reaches balance, no longer rotates, and realizes the closing function of closure.
When reducing the supply current of reluctance machine 4, the torsional moment of reluctance machine 4 synchronously reduces, and rotor 5, valve rod 2 and valve block 3 reverse under the flywheel moment effect of torsion spring 9, thus plays the effect controlling magnetoresistive type electronic throttle aperture.When the supply current of reluctance machine 4 is in a certain fixed value, the torsional moment of reluctance machine 4 is equal with the torsional moment of torsion spring 9, namely rotor 5 and torsion spring 9 are in a certain balance, all no longer rotate, even if magnetoresistive type electronic throttle is stable be in a certain aperture; Change the supply current of reluctance machine 4, rotor 5 and torsion spring 9 reach balance again, thus magnetoresistive type electronic throttle are stablized be in a certain new aperture; Namely the linearity control of magnetoresistive type electronic throttle is achieved.
