Abstract
The invention relates to a throttle control system for an electronic controlled engine of a bulldozer. A manual throttle controller for increasing a throttle rotating speed of the engine, which can increase the throttle rotating speed from minimum to maximum, is connected with an engine controller by a wire; a foot-operated throttle controller for decreasing the throttle rotating speed, which can decrease the maximum rotating speed of the manual throttle controller of the engine at the current position to the minimum, is connected with the engine controller by the wire; and a signal end of the output of the engine controller is connected with the throttle controllers of the engine by the wires. The throttle control system for the electronic controlled engine of the bulldozer has the advantages of simple and reasonable structure and arrangement, easy operation, high control precision and stable control performance. The throttle double-control system realizes that when the bulldozer runs, a driver can conveniently, safely and accurately realize high-efficiency matching control of the load and the engine rotating speed, ,so that the throttle control system is more energy-saving and efficient, has better discharge and can satisfy various complex working conditions.
Description
Technical field:
The present invention relates to a kind of throttle control system for electronic controlled engine of bulldozer, can realize the manual and dual control of foot-propelled of bulldozer electric-control motor throttle.
Background technology:
Operating environment that bulldozer is abominable and violent changeable working load have proposed high requirement to the reasonable use and the control of machine.The tradition bulldozer mainly adopts machinery control engine throttle, promptly by the control of realizations such as handle, rocking arm, connecting rod to engine throttle opening, and complex structure, and control accuracy is relatively poor.Raising along with progress of science and technology and energy-conserving and environment-protective requirement, at present electric-control motor has obtained paying close attention to widely and using in engineering machinery field, how to the bulldozer electric-control motor carry out safety, rationally, effectively, control reliably just become a new problem.
Summary of the invention:
The purpose of this invention is to provide a kind of bulldozer electric-control motor control system, bulldozer is realized manual, the dual control of foot-propelled with the electric-control motor throttle, thereby carry out more effective, reliable control, realize the reasonable coupling between motor and the machine loading.
The objective of the invention is to realize as follows: the hand throttle controller that can be increased to maximum increase engine throttle rotating speed from the throttle rotating speed of minimum is connected with lead with engine controller; Motor hand throttle controller current location maximum (top) speed can be reduced to the minimum foot-propelled throttle control that reduces the throttle rotating speed and be connected with lead with engine controller, the signal end of engine controller output is connected with the engine oil door controller by lead.The hand throttle controller is used to increase the engine throttle rotating speed, can be increased to maximum from the throttle rotating speed of minimum; The foot-propelled throttle control is used to reduce the throttle rotating speed, motor hand throttle controller current location maximum (top) speed can be reduced to minimum.During work, set a maximum speed value with the hand throttle controller according to need of work earlier, regulate with the foot-propelled throttle control, this kind method is not only simple to operate, control is reliable, and is easy to realize reaching between motor and the load effect of optimum Match.Make efficient energy-saving, discharging more better, more can adapt to the operating mode of various complexity.
Hand throttle controller and foot-propelled throttle control that the present invention selects all adopt Linear Control, and control accuracy can be effectively guaranteed like this.Requirement according to ergonomics principle and control reasonability, reliability and accuracy, the anglec of rotation and the corresponding magnitude of voltage of regulation hand throttle controller, foot-propelled throttle control all have clear and definite technical stipulation, simultaneously, set up strict linear corresponding relation between the aperture of the size of voltage and throttle.When hand throttle is in original position, the voltage minimum of signal end output, throttle minimum; When hand throttle rotates to maximum angle, the voltage maximum of signal end output, throttle maximum.The most at the beginning, the foot-propelled throttle is on the maximum position, the voltage maximum of signal end output, throttle maximum; When the foot-propelled throttle jams on extreme lower position, the voltage minimum of signal end output, throttle minimum.During work, general driver can reach maximum or any one throttle position wherein to manual throttle control knob earlier, allows motor turn round under its rotating speed; Can control engine throttle by the foot-propelled throttle control when needing to slow down, engine speed begins to descend when stepping on the foot-propelled throttle control; Unclamp the foot-propelled throttle control, engine speed is got back to the throttle position at hand throttle controller place again.
It is stable that structure of the present invention is provided with advantages of simple, processing ease, control accuracy height and control performance; This throttle double-control system has been realized bulldozer when operation, and the driver can make things convenient for, safety, realize the efficient coupling control of load and engine speed making efficient energy-saving, discharging more better, more can adapt to the operating mode of various complexity exactly.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
With reference to accompanying drawing, the hand throttle controller 1 that can be increased to maximum increase engine throttle rotating speed from the throttle rotating speed of minimum is connected with engine controller 2 usefulness leads; Motor hand throttle controller 1 current location maximum (top) speed can be reduced to the minimum foot-propelled throttle control 3 that reduces the throttle rotating speed and be connected with engine controller 2 usefulness leads, the signal end of engine controller 2 outputs is connected with engine oil door controller 4 by lead.
