Abstract
The utility model provides an automatic accelerator adjusting device for electric control environment sanitation vehicle. The technical proposal of the utility model is that a pressure transmitting device which is connected with the output end of an oil pump is connected with a main oil pipe of a power device; and the three units of contactors of the switch are respectively connected with the voltage signal wire of an accelerator pedal angle sensor, the idle speed detecting signal part of an on-board microcomputer control board, and the output signal wire of a pressure transmitting device. The pressure transmitting device takes a pressure transmitter or an integrated pressure transmitter. The vehicle automatically adjusts the rotation speed of the engine according to the feedback pressure degree of the actual working condition. The rotation speed of the engine is in direct proportion with the actual working pressure, so that the rotation speed of the engine is decreased low, when the pressure is relative small, thereby effectively decreasing the fuel consumption and saving source. The system automatically chooses a proper rotation speed of the engine when the pressure is large, thereby avoiding flameout of the engine due to over load.
Description
Technical field
The utility model relates to a kind of throttle automatic adjustment technology, especially is applicable to the throttle automatic regulating device in the environmental sanitation vehicles work of adopting electric-control motor.
Background technique
During garbage compression vehicle work, because of moving complexity, each working state force value is not of uniform size, usually need the driver to strengthen according to actual conditions or the minimizing throttle, and environmental sanitation vehicles adopts back compression type mode more more, the driver can't leave the rubbish compression situation that operator cabin is watched the tailstock, needs many people to cooperate, and increases operator so virtually.
Summary of the invention
The purpose of this utility model provides a kind ofly regulates the device of throttle automatically according to pressure feedback, and the size of the output signal of this device changes with the pressure size, by changing magnitude of voltage control engine speed change, satisfies need of work.
The purpose of this utility model realizes as follows:
The pressure inverting device that is connected with the oil pump output terminal is connected with the working connection of power plant, three groups of contacts of switch are connected with accelerator pedal angle sensor voltage signal line respectively, with car inner microcomputer control panel on the idling testing signal partly be connected, be connected with the output signal line of pressure inverting device.The pressure inverting device is meant pressure transmitter or integrated pressure transmitter.
Transmitter output 0～5V voltage, the size of voltage is changed by the pressure size.This magnitude of voltage is replaced primary electron accelerator pedal sensor signal and is connected the EFI automatic controller, requires input 0V voltage during this EFI automatic controller idling, requires near 5V during maximum (top) speed.Engine speed and this input voltage value are proportional.Pressure reduces, and output voltage reduces, and the corresponding reduction of engine speed is not when vehicle is worked, pressure transmitter is output as 0V, and vehicle is with idle, and pressure increases during work, the transmitter output voltage increases, and the voltage that inputs to the EFI automatic controller increases the corresponding raising of engine speed.
This device applying pressure transmitter realizes regulating automatically the electronic fuel injection engine rotating speed, vehicle is regulated engine speed automatically according to the pressure size of actual conditions feedback, and engine speed and actual working pressure are proportional, pressure than hour, engine speed is low, can effectively reduce oil consumption, save the energy, when pressure is big, the engine speed that system is corresponding suitable automatically, be unlikely to cause engine misses, can effectively save the labour force, alleviate driver's burden because of load is excessive.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to accompanying drawing, at vane pump oil circuit output terminal and connect a pressure transmitter or adopt the integrated pressure transmitter, transmitter output 0～5V voltage, the size of voltage changes with the pressure size.Pressure inverting device (or adopting the integrated pressure transmitter) is connected with the working connection of power plant, system pressure changes under the testing state, by changing pressure inverting device (or adopting the integrated pressure transmitter) output signal, the electronic fuel injection engine rotating speed is regulated in final realization automatically; One group of contact of switch is connected with accelerator pedal angle sensor voltage signal line, is used for connecting and cutting off the accelerator pedal angle sensor voltage signal; The idling testing signal partly is connected on another group contact and car inner microcomputer control panel of switch, is used to cut off the attachment portion of idling testing signal and car inner microcomputer control panel; Another group contact again of switch is connected with the output signal line of pressure inverting apparatus (or adopting the integrated pressure transmitter), is used to switch to pressure inverting device (or adopting the integrated pressure transmitter) and connects the microcomputer control panel signal input.Cut off the attachment portion of accelerator pedal angle sensor voltage signal and cut-out idling testing signal and car inner microcomputer control panel during work by switch, switch to the pressure inverting device simultaneously and connect the microcomputer control panel signal input.Efp is a 0V voltage during because of automatically controlled car idling, efp voltage is near 5V during maximum engine speed, select the pressure transducer of suitable range according to the actual pressure of car load design, when being 15MPa as the pressure maximum of vehicle design, select the pressure transducer of 0～40MPa, when vehicle operation reached pressure maximum, transmitter output maximum working voltage was about 1.8V, engine speed reaches 1500 revolutions per seconds, has reached actual loading requirement rotating speed.Pressure reduces, and output voltage reduces, the corresponding reduction of engine speed, and when vehicle was not worked, pressure transmitter was output as 0V, and vehicle is with idle.
Vehicle is regulated engine speed automatically according to the pressure size of pressure inverting apparatus (or adopting the integrated pressure transmitter) feedback actual conditions, engine speed and actual working pressure are proportional, pressure inverting apparatus (or adopting the integrated pressure transmitter) output voltage values is corresponding with microcomputer control panel signal input magnitude of voltage, the size of its output signal changes with the pressure size, by changing magnitude of voltage control engine speed change, satisfy the rotating speed of need of work, finally satisfy the working pressure of hydraulic system.
Close two rotary switches, recovery accelerator pedal angle sensor signal and idling testing signal are connected with automatically controlled plate, and vehicle can normally be walked.Switch can be realized the switching of cruising and two kinds of situations of Parking work, satisfies actual demand.
