- Control Of Throttle Valves Provided In The Intake System Or In The Exhaust System (AREA)
Abstract
The utility model relates to an automatic control device for a throttle of a car, which comprises a stepping motor and a throttle regulating device, wherein the regulating device changes an angle of a throttle 3 and an axial lead between an idle-speed nozzle 11 and an idle-speed filtration nozzle 12, and the regulating device is a double-rocker mechanism. The output end of the stepping motor 1 is connected with one end of a driving rocker 5, and the other end of the rocker 5 is hinged with one end of a connecting rod 6. The other end of the connecting rod 6 is hinged with one end of a driven rocker 4, and the other end of the rocker 4 is fixedly connected with a throttle axle 3.
Description
The utility model is relevant with the automatic control mechanism of air throttle of car, and is especially relevant with the regulating device of auto idle speed.
The adjustment of auto idle speed is directly connected to exhaust emissions amount and the engine running stationarity under the auto idle speed state, adjustment is the adjustment process to a kind of trace of air input of engine by air to auto idle speed, usually carry out with the following methods: a kind of is moving by the no-load jet inner needle valve, change the charge flow rate of idle metering jet, another kind of mode is to establish an adjusting screw rod in closure complete shut-down position, carry out spacing to closure complete shut-down position, by the adjusting to screw rod, the trace between change closure and idle jet and the idling filtration spout is swung and is carried out the auto idle speed adjustment.Hence one can see that: directly when the throttle adjustment idling, because the restriction of stepper motor step angle explanation degree can not be carried out the trace adjusting to closure during idling, cause the rough running under the idling mode of motor with stepper motor.
The purpose of this utility model provides a kind of can carry out the air control shutter automatically controlling device that trace is regulated to closure when idling.
Another purpose of the present utility model provides a kind of simple in structure, only finishes the air control shutter automatically controlling device that Carburetor idling and throttle opening are controlled jointly with a stepper motor.
The utility model is achieved in that
The utility model has adopted a kind of two linkage of broadcasting between stepper motor and throttle plate pin, when closure is in idle position, passive rocking bar is in limit position, angle α setting value is more little between the elongation line of drive crank and connecting rod medial axis at this moment, connecting rod is also more little in the corresponding displacement of in-plane, the swing of passive connecting rod is also more little, the amplitude of fluctuation of closure is reduced, hence one can see that: when the stepper motor revolution moves a step angle in the angle α, drive closure and only make very small sway, thereby form the trace adjustment to closure, the adjustment of throttle opening is by the displacement transducer control of automobile accelerator pedal under the non-idling mode of the utility model.
The utility model is because stepper motor of employing is promptly finished the control to closure idling and aperture, additional correspondent control circuits, make its automation, therefore have highi degree of accuracy, high stability and advantages of simple structure and simple, significant at vehicle automatic transmission, automatic cruising and auto idle speed controlling party mask.
Following is the utility model accompanying drawing:
Fig. 1 is the theory diagram that the utility model is formed.
Fig. 2 is the structural drawing of another kind of mode of execution of the present utility model.
Following is embodiment of the present utility model:
Accompanying drawing shows and is designated as stepper motor 1 among Fig. 1, Fig. 2; Double rocker mechanism 2; Air throttle of car axle 3.
Among the figure, idle signal 8 and acceleration pedal position signal 9 are controlled by 7 pairs of stepper motors 1 of drive controller, and stepper motor 1 links to each other with throttle plate pin 3 by double rocker mechanism 2, thereby finish the automatic control of throttle opening and idling.
Of the present utility model as shown in Figure 2 initiatively broadcasting in the rotating shaft that bar 5 is fixed on stepper motor 1, and hinged with connecting rod 6, and passive rocking bar 4 is fixed on the throttle plate pin 3, the other end and connecting rod 6 are hinged, thereby constitute a kind of double rocking lever driving mechanism, in addition, throttle plate pin 3 is connected with closure 10.
The movement position of idling mode when solid line is depicted as closure near the group of closing among Fig. 2, this moment, passive rocking bar was in the limit on the right-right-hand limit position, and position shown in the dotted line is the WOT state, and passive rocking bar is in the limit on the left position.Under the idling mode shown in the solid line, because angle α levels off to 0 ° more between the elongation line of connecting rod 6 and drive crank 5 both medial axis, the swing of connecting rod on in-plane also goes to zero more, the swing that is reflected on the closure 10 by passive connecting rod 4 and throttle plate pin 3 also levels off to zero, hence one can see that, and it is a kind of swing of trace that interior each step angle of stepper motor of angle α scope is reflected on the closure 10.
In the foregoing description; because angle α can be 0 ° between the elongation line of connecting rod 6 and drive crank 5 both medial axis; define according to mechanology: double rocker mechanism 2 also can be understood as a kind of crankrocker mechanism in the utility model when angle α is 0 °, therefore will be subjected to protection of the present utility model equally.
