Description
Technical field
The present invention relates to technical field of engineering machinery, in particular to the throttle control system and controlling party of a kind of engineering machinery
Method.
Background technique
Current engineering machinery throttle mainly includes foot throttle and long-range throttle, and foot throttle is also known as throttle of getting off, long-range oil
Door is also referred to as hand throttle, throttle of getting on the bus.
Both foot throttle and long-range throttle are typically designed as integrated throttle component, and integrating in throttle component includes that foot throttle is grasped
Vertical component, long-range gas pedal, control circuit, foot throttle control member, long-range gas pedal are all connected with control circuit, to incite somebody to action
The signal of the two is transferred to control circuit, control circuit to the foot throttle control member and long-range accelerator pedal signal received into
Then row integrated treatment sends signal in engine.
Demand of the different engineering machinery to throttle is different in the prior art, according to the difference of control model, above-mentioned integrated oil
Door component generally comprises three classes: standard throttle integrates throttle component, throttle takes small integrated throttle component, throttle to take throttle integrated greatly
Component；Wherein, standard throttle integrates throttle component and mainly realizes the alternating control for receiving throttle and long-range throttle, i.e. foot throttle is row
Vehicle throttle, long-range throttle are constant speed control throttle.Throttle takes throttle component integrated greatly to realize following control mode: working as foot throttle
Engine is controlled after certain revolving speed, the aperture of rotation hand throttle to foot throttle.Foot throttle can be unclamped at this time, engine turns
Speed is constant, to achieve the purpose that constant speed.Throttle takes small integrated throttle component to realize following control mode: when starting the engine,
Engine idling operation.Hand throttle is moved to certain revolving speed.Foot throttle is stepped on as idling, comes up, revolving speed slowly oil in one's hands
The revolving speed of door setting.
In the prior art because integrated throttle component is an integral structure, once the integrated a certain pedal of throttle component or controller
It goes wrong, the integrated throttle component of original can only be removed completely, more renew integrated throttle component, maintenance cost is relatively high.
In addition, each integrated throttle component can only realize the accelerator mode control of a certain independent mode, because integrating throttle component
It is installed on the inside of the driver's cabin of engineering machinery, usual engineering machinery can only select the integrated throttle component installation of a control model,
Engineering machinery cannot integrate the control model of throttle component according to environmental condition unrestricted choice in this way, lead to the control of engineering machinery
