According to the electric control system for the engine throttle, multi-point control of the opening degree of the engine throttle is achieved through a plurality of electrical control throttle units, requirements for engine power when multifunctional construction mechanical equipment achieve various functions are met, and requirements for operation habits of various customers are met simultaneously.
Description
Technical field
The present invention relates to the engine throttle automatical control system of a kind of throttle control system of motor, particularly a kind of engineering mechanical device.
Background technique
Traditional mechanical engine adopts the aperture of acceleration cable control throttle, to reach the control of the output power to motor.At present mechanical throttle is realized the conventional method of automatically controlledization transformation, also just simply with a potentiometer type throttle and controller, actuating motor is controlled, then pull throttle flexible axle by actuating motor, engine throttle is controlled.Same existence can only be controlled at a control point, cannot realize the shortcoming of two control points or multi-control point control; For the Versatile Construction Machinery such as glide steering loader or loader-digger equipment, for realize other functions or for meet all kinds of client's operating habits often needs adopt multiple spot control throttle, the structure of tradition machinery can only realize at most parallel 2 manipulations of manual accelerator control and foot throttle, but this mechanical structure main devices is a flexible axle and a mechanical handle, accurately control difficulty large, the main experience that relies on operator, and due to the restriction of self mechanical structure, cannot realize two control points or multi-control point control.
Summary of the invention
Goal of the invention: the object of this invention is to provide a kind of engine throttle automatical control system that can realize multiple spot control.
Technological scheme: a kind of engine throttle automatical control system, comprise electricity-controlling throttle, controller, actuating motor, engine mechanical throttle and throttle flexible axle, electricity-controlling throttle is connected with controller respectively with actuating motor, and actuating motor is by throttle flexible axle manipulation engine mechanical throttle; Described electricity-controlling throttle comprises at least two electricity-controlling throttle unit in parallel, described controller gathers the signal of each electricity-controlling throttle unit and actuating motor simultaneously, the more each signal of controller according to program by operation result with control signal formal output to actuating motor, described actuating motor is by the aperture of throttle flexible axle control engine machinery throttle.The present invention has realized multiple spot control engine accelerator open degree by multiple electricity-controlling throttles unit, met Versatile Construction Machinery equipment in the time realizing various function to engine power demand, also meet the demand of all kinds of client's operating habits simultaneously.
Preference, described controller carries out comparing calculation and goes out the actual aperture of throttle according to actuating motor feedback signal and its full scale signal; Described controller is according to the input signal of the not highest electricity-controlling throttle unit of the priority execution priority of the each electricity-controlling throttle unit setting in advance; The result output control signal that described controller compares according to the actual opening value of the input signal of performed electricity-controlling throttle unit and throttle is to actuating motor, actuating motor determines the number of turns that turns to and rotate of motor according to input signal, and when the signal value that feeds back to controller when actuating motor equates with the signal value of electricity-controlling throttle unit, actuating motor shuts down.
Preference, described electricity-controlling throttle comprises the first electricity-controlling throttle unit and the second electricity-controlling throttle unit, described the first electricity-controlling throttle unit is foot throttle, and described the second electricity-controlling throttle unit is manual accelerator control, and the priority of described the first electricity-controlling throttle unit is lower than the second electricity-controlling throttle unit.The setting principle of the rank of each electricity-controlling throttle unit is that the electricity-controlling throttle unit priority level of commonly using is lower.
Beneficial effect: the present invention has realized multiple spot control engine accelerator open degree by multiple electricity-controlling throttles unit, met Versatile Construction Machinery equipment in the time realizing various function to engine power demand, also meet the demand of all kinds of client's operating habits simultaneously.
