Description

Vehicle auto-throttle controller

The utility model relates to the automatic control of vehicular propulsion supply of fuel.Specifically refer to vehicular propulsion, with the throttle automatic controller of Carburetor fuel supplying.

Basically petrol engine is done vehicle powered at present, supply of fuel by Carburetor with gasoline and air mixing after, send into the cylinder of motor, ignition produces power.Carry fuel-air mixture to enter on the passage of cylinder at Carburetor an air door is set, the aperture size of control door opening reaches mixed gas and enters what of cylinder, thereby changes the intensity of burning, the rotating speed of control motor.The common name throttle.The automatic speed changing vehicle when changing car speed, during the common name Vehicular shift, need be in this moment of gear shift, engine speed reduces.This just needs throttle can control the variation that reaches required size automatically when automobile automatic gear.Present this throttle pattern is more.The applicant is to disclose a kind of design in the 97226476.0 vehicle auto-throttle controllers at application number.Turning on an angle or the rocking arm of a removable segment distance, a balance arm is set, the two ends of balance arm are connecting air door (throttle) on the Carburetor and the accelerator pedal on the vehicle with lacing wire respectively.When starting vehicle, the driver steps gas pedal, and the pulling balance arm turns over an angle, and door opening is refueled.When the need gear shift, electronic automatic controller by program control, makes rocking arm turn over an angle, reaches and loosens lacing wire, changes the aperture of air door, makes engine retard.The length of the lacing wire of loosening turns over an angle by steady arm and adapts to, and need not change the position that the driver steps gas pedal.Throttle when having finished gear shift is controlled automatically.This Throttle Opening Control advantage is a lot, safe in utilization.Rocking arm and steady arm, as long as there is one to subtract oil, entire controller just subtracts oil, has only two to refuel simultaneously, controller could refuel.The driver artificially adds and subtracts oil and is realized by gas pedal, and when program control plus-minus oil was used in gear shift, mutual noninterference can occur simultaneously, finishes separately.But a problem is in use arranged, and it is uncomfortable that the driver feels.That is exactly when gear shift, when subtracting the oil beginning, rocking arm begins rotation and subtracts oil to having changed shelves, and rocking arm goes back to original position, the throttle returning position, although the position that steps that is gas pedal does not change, the length change of throttle lacing wire is gone to replenish by the rotation of balance arm, and being reflected in the lacing wire is that lacing wire does not stress, thereby the gas pedal of driver underfooting does not stress yet, similarly be to have disappeared suddenly, imperceptible, use uncomfortable.

The vehicle auto-throttle controller that the purpose of this utility model is intended to design keeps should reaching usage requirement in the auto-throttle use, and is safe and reliable, easy to use, and manually plus-minus oil and the oily mutual noninterference of automatic deceleration can occur simultaneously, finish separately.Emphasis solves driver uncomfortable in using, and makes the driver in use as broad as long with the throttle of used hand shift, prevents from traffic accident to occur because of the difference that adapts to service condition.

The utility model is finished by following technological scheme.The passage lower end of leading to cylinder at former car engine Carburetor, fuel-air mixture, set up one section thin casing, establish two isolated mutually chambeies in the casing, two chambeies all communicate with the Carburetor gas channel, a part of forming passage, but be provided with the valve in this chamber of opening and closing of fault in one of them chamber, Carburetor gas channel lower end, it is exactly the base position of Carburetor, the thin casing shape of cross section that increases is identical with the shape of cross section of base, with the mounting screw of former Carburetor with this casing jam-packed between former carburettor base and engine inlets ingress.After producing, typing this casing cast solid of Carburetor casing and increase can be formed special-purpose Carburetor on the motor of automatic speed changing vehicle.Wherein can open the valve in this chamber of sealing in the chamber, identical with the closure pattern of former carburetion gas, also be slat belt, the pattern of its control action can be used pneumatic valve, also can adopt the program control of other patterns such as micro motor by electronic controller.The design's improvement principle is very simple, and former carburetor throttle is not related with the valve of setting up by the gas pedal control of vehicle, so the driver can not produce the sensation of difference in use.The twice air door, one air door action can not produce the effect of refueling, and the twice air door strengthens simultaneously, just may refuel.If but have one air door to subtract oil, whole device promptly subtracts oil.Simply, practical, safety, the utility model has reached purpose of design.

Be illustrated as the utility model when the Xiali automobile is improved to the automatic speed changing car, the repacking of its auto-throttle controller.Now propose, so that the utility model is further described as a kind of typical structure.

Drawing explanation: 1. paper washer, 2. auto-throttle controller shell, 3. throttle plate pin, 4. rocking arm, 5. bearing pin, 6. packing ring, 7. jump ring, 8. sensor, 9. screw, 10. sensor support frame, 11. pneumatic valves, 12. cruciform slot screws, 13. the closure valve block, 14. mixed gass are adjusted screw, 15. locking springs, 16. screw, 17. screws.

The utility model auto-throttle controller shell 2 is very thin, and its shape of cross section is identical with the shape of cross section of the carburettor base of manual Xiali car, and between base and motor intake grill, the centre adds paper washer 1 sealing with the screw jam-packed on original base.Two cavitys that communicate with the Carburetor passage, the design is circular, also can be other Any shape.Separate between two chambeies, wherein a slat belt closure is established in a chamber, and closure valve block 13 usefulness Cross Recess Head Screws 12 are fixed on the throttle plate pin 3, and throttle plate pin 3 is supported on the housing 2 and can rotates.When shift speed change, drive pneumatic valve 11 actions by the electronic program control electromagnetic valve, draw to push away Rocker arm 4, throttle plate pin 3 is rotated, opening and closing of fault closure valve block 13 realizes refueling or subtracting oil.It all is the accessory that the Xiali automobile is now just using that pneumatic valve 11 and air feed are given the solenoid valve of pneumatic valve.The sensor 8 of dress is contained in the air door rotating shaft of former Carburetor on the sensor support 10, transmits the enable possition of carburetor throttle and gives electronic controller.All petrolic vehicles, the control of repacking auto-throttle all can be used the utility model, in Carburetor ventilation flue lower end, base position installs this design additional, and its shape of cross section is identical with base, uses the mounting point and the screw of former Carburetor, need not change original structure, can not change the oiling performance of former vehicle, can also reach with program control when shifted, the vehicle fuel delivery subtracts the variation that adds.Need not change driver's use habit.Use through reality, reach the purpose of this utility model.

Enforcement is finished.

Claims (1)

1, in housing, if fuel-air mixture passage, and in this passage, be provided with the vehicle auto-throttle controller of the automobile carburetor formula of throttler valve, it is characterized in that leading to the passage lower end of cylinder at the automobile carburetor fuel-air mixture, set up one section thin casing, establish two isolated mutually chambeies in the casing, two chambeies all communicate with the Carburetor gas channel, form the part of passage, but be provided with the valve in this chamber of opening and closing of fault in one of them chamber.
