Summary of the invention
Technical problem to be solved by this invention provides a kind of petrol engine electronic air throttle body, and it has replaced the existing mechanical Placement and has all directly been driven by direct current generator under any operating mode, improves power character, Economy and the Security of motor.
For solveing the technical problem, the invention provides a kind of petrol engine electronic air throttle body, it is characterized in that, the petrol engine electronic air throttle body comprises the closure housing, the closure valve block, throttle plate pin, bearing, Returnning spring, the coupling spring, intermediate gear, motor gear, the coupling ring leg, adjusting screw, the throttle plate pin assembly, first make contact, reseting gear, magnet assemblies, second point of contact, coupling ring, the axial limiting plate, first hanging feet, second hanging feet, the contact copper sheet, motor pressing plate and direct current generator, cooperate in the groove of closure valve block insertion throttle plate pin and with the closure body clearance, throttle plate pin is connected with bearing element, coupling one of spring turns round that arm hangs on first hanging feet and another is turned round arm and hangs on second hanging feet, reseting gear rotates coupling ring under the effect of coupling spring fan-shaped bump contacts with first make contact, and the coupling ring leg withstands on the adjusting screw, reseting gear and throttle plate pin assembly weld together, one of Returnning spring turns round that arm hangs on the closure housing and another is turned round arm and hangs on the coupling ring, direct current generator drives reseting gear by intermediate gear and rotates the torsion that overcomes the coupling spring when throttle body need be closed, the fan-shaped bump of coupling ring is contacted with second point of contact, magnet assemblies is fixed on the throttle plate pin, throttle plate pin becomes as a whole with the axial limiting plate by Shooting Technique, direct current generator is located and is fixed on the closure housing by the motor pressing plate, motor gear and intermediate gear engagement, the contact copper sheet passes from two holes of motor pressing plate.
Preferably, described axial limiting plate be injection-moulded on the throttle plate pin and be assemblied in bearing and the closure housing between.
Preferably, described petrol engine electronic air throttle body also comprises sensor pcb, copper coin inserts, shoulder guard and dust cover, sensor pcb, shoulder guard, copper coin inserts and dust cover constitute the dust cover assembly, shoulder guard is attached in the sensor pcb back and the dust cover of packing into, and the copper coin inserts is built in the dust cover by Shooting Technique.
Preferably, described petrol engine electronic air throttle body also comprises direct current generator jack and wire harness socket, the contact copper sheet inserts two direct current generator jacks, and the wire harness socket becomes as a whole by Shooting Technique with dust cover, and direct current generator is connected with the wire harness socket by the copper coin inserts.
Positive progressive effect of the present invention is:
One, the dust cover assembly is integrated drive circuit, the socket of inside and outside communication, the sensor pcb of process angle position information, former design are to connect by soldering, occur easily that rosin joint etc. causes the void of whole circuit short, empty disconnected risk.This design adopts contact-type to connect, utilize the toughness of copper coin material and the plasticity of plastics, when the contact copper sheet on the direct current generator is inserted into the direct current generator jack on opposite, two contact copper sheets have produced enough impacting forces between the two because the toughness generation elastic strain of self makes, under the shock conditions that is subjected to the external world, can not break away from yet, and also shortened the technological process of assembling, the risk of having avoided rosin joint to connect.
Two, the design of EMR emergency reset system: the EMR emergency reset system design is made up of elements such as reseting gear, coupling ring, coupling spring, throttle plate pin assembly, Returnning springs, function is a throttle body when dead electricity or other are impaired, can make throttle body be closed to default location from any position of opening; Because throttle body drives reseting gear and rotates an angle under the coupling spring action, throttle body can not be closed under the effect of Returnning spring fully, can provide a stable emergent air mass flow to motor like this.Its structure characteristic is: turn round arm for one of Returnning spring and hang on the closure housing, another is turned round arm and hangs on the coupling ring.Reseting gear is pressed into the barb that utilizes in the coupling ring on the gear and hangs over and avoided disengaging between the two on the coupling ring then, makes coupling ring, coupling spring, reseting gear become as a whole.During assembling, under the active force of coupling spring, the fan-shaped bump above the coupling ring cooperates with first make contact, i.e. the default location of throttle body; When throttle body need be closed, the fan-shaped bump and second point of contact were fitted.Then the above emergency system parts that assemble are installed on the throttle plate pin, allow an end of Returnning spring hang on the coupling ring, the other end hangs on the closure housing, and the coupling ring leg withstands on the adjusting screw, and reseting gear and throttle plate pin assembly are welded together.This structural advantages is the conformity that has guaranteed emergent angle, and the flow of promptly meeting an urgent need has obtained stable and consistent in manufacture process; And this project organization is ingenious, has improved assembling.
Three, the direction shifting amount of throttle plate pin design: the characteristics of this project organization are because throttle plate pin makes between axial limiting plate and the body bearing hole step surface to a direction play at the drop-down moving axis of Returnning spring compressive force enough gap is arranged, and the axial limiting plate is close to bearing face, bearing face and the sliding friction of axial limiting plate when bearing rotates.Advantage is that the axial limiting plate is injection-moulded on the throttle plate pin, and the axial limiting plate adopts wear-resisting engineering plastics and smooth bearing face slip, thereby friction factor is very little, has increased the life-span of axial limiting plate.
Four, motor platen design: this design benefit is to cancel parts such as installing and locating and the needed positioning ring of damping, wave washer in the past, utilizes the toughness damping of the embedded steel part of motor Anchor plate kit.And the cylindrical of motor Anchor plate kit endoporus that cooperates with motor and the motor Anchor plate kit that cooperates with body adopts disposable precise injection molding, has guaranteed the reliability of motor installing and locating, has reduced the installation variation.
Five, the structural design of non-contact sensor: the sensor pcb that has the angular orientation is encapsulated in the dust cover, magnet assemblies is pressed in the pre-hole of throttle plate pin, sensor is by the variation of induced magnet intensity, calculate the variation of throttle position, it is little that advantage is that magnet takes up room, and the shoulder guard that prevents external interference is housed in the sensor pcb back, make the signal stabilization of output and accurately.
