Abstract

The present invention 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

Automatic controller for air throttle of car

The present invention 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 auto idle speed adjustment is carried out in the little heavy swing that changes between closure and idle jet and the idling filtration spout.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.

Purpose of the present invention provides a kind of can carry out the air control shutter automatically controlling device that trace is regulated to closure when idling.

Another object of the present invention 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 present invention is achieved in that

Automatic controller for air throttle of car of the present invention, comprise stepper motor 1 and throttle adjustment device, controlling device changes the angle of the shaft axis between closure and idle jet 11 and the idling transition spout 12, it is characterized in that controlling device is a double rocker mechanism, one end of stepper motor 1 output shaft and drive crank 5 is connected, one end of drive crank 5 the other ends and connecting rod 6 is hinged, and an end of the other end of connecting rod 6 and passive rocking bar 4 is hinged, and the other end of rocking bar 4 and throttle plate pin 3 are connected.

When closure of the present invention was in the complete shut-down position, passive rocking bar 4 was in limit position.

When passive jack back 4 was positioned at limit position, the elongation line angle α of the medial axis of drive crank 5 and connecting rod 6 was :-30 °≤α≤30 °.

The present invention has adopted a kind of double rocker mechanism 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 present invention 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 accompanying drawing of the present invention:

Fig. 1 is the theory diagram that the present invention forms.

Fig. 2 is the structural drawing of another embodiment of the invention.

Following is enforcement side of the present invention:

Accompanying drawing shows that being designated as the step keeps away 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.

Drive crank 5 of the present invention as shown in Figure 2 is fixed in the rotating shaft of 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.

Solid line is depicted as the movement position of idling mode when closure is approaching closes among Fig. 2, and 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 among the present invention when angle α is 0 °, therefore will be subjected to protection of the present invention equally.
