Description
The utility model belongs to the device of automatic guidance car speed and the fuel-economizing of energy auto-supply.
Patent gazette the 7th volume discloses a kind of I. C engine fuel auto-supply and saving device No. 15, be that the negative pressure that air inlet pipe produces during with internal combustion engine is a power, cause that according to rotation speed change intake pipe negative pressure changes principle and implements auto-supply, by the Throttle Opening Control parts, speed-regulating part and speed governing positioning element three parts are formed, and have characteristics such as fuel feeding is accurate, simple in structure, easy to install.In actual use, find that structure is extremely unreasonable, following problem generally occurs: 1, be used to control the speed of a motor vehicle, throttle wire cable rupture, come off; 2, switch very fast damage under constantly impacting; 3, easily shake is disconnected in vehicle traveling process for the breather pipe of gas circuit assembly; This apparatus structure is loose, causes poor reliability, and product can't ordinary production use, and is under test all the time.
The purpose of this utility model provides a kind of simple and compact for structure, easy for installation, accurate automobile speed automatic control device of auto-supply.
The purpose of this utility model is achieved in that this device is made up of gas circuit assembly, Throttle Opening Control part, speed governing localization part, ventilation switch, the ventilation switch is made up of electromagnetic valve 11 grades, the housing inner chamber is divided into fine setting cylinder 20, speed control cylinder 9 two parts, housing 5 two ends are sealed by two end cap, are provided with air passage 6 in the housing 5; Directly enter fine setting cylinder 20 after air inlet pipe 2 air inlets of sending and receiving motivation, the air passage by right end cap 12 and speed governing cover 13 enters the speed control cylinder, and the air passage of right end cap 12 and housing 5 interior air passages are communicated with; Be provided with big valve piston 7,19 in the fine setting cylinder 20, piston is arranged vertically and is put, and piston rod 3 axially connects piston, passes the left end cap 4 of housing 5, is connected with engine throttle by flexible axle 1; Pressure cap 14 is connected with piston rod 3 other ends, and controlling spring 18 is between big piston 7 and pressure cap 14; Be provided with speed governing cover 13 in the speed control cylinder 9, the outside face of speed governing cover 13 has shifting chute, and big piston 7 is enclosed within on the speed governing cover 13, can overlap the screw pin 8 that 13 shifting chute moves along speed governing and be connected with big piston 7; Speed governing cover 13 is enclosed within right end cap 12 endoporus; Being arranged on the air passage that throttle power fine setting 16 on the housing 5 and swivel nut 17 form communicates with the groove of big piston 7; Fine setting cylinder 20, piston 7,19, piston rod 3, pressure cap 14, the Throttle Opening Control part is formed in controlling spring 18, throttle power fine setting 16; Speed control cylinder 9, screw pin 8, speed governing cover 13 etc. are formed the speed governing localization part.
The fine setting of throttle power is made up of the fine tuning valve that can make the gas passage size variation, and an end is coniform, and the other end is the needle-valve 16 of screw tail shape; Swivel nut 17 is made up of compression spring and steel ball, and compression spring is pressed on steel ball on the air passage; Controlling spring is a compression spring, the track of the shifting chute of speed governing cover for making screw pin 8 location and move along speed governing cover surface along circumference 180 degree; The air intake branch 2 of gas circuit assembly directly passes or directly passes housing 5 from end cap, gas circuit communicates with fine setting cylinder 20 and speed control cylinder 9 then.
Because speed governing part, control part and gas circuit assembly are arranged in the housing simultaneously, speed governing part and control part are bonded together, gas channels is arranged in housing and the end cap, make this apparatus structure simple, compact, can not damage breather pipe because of thump, destroy the gas circuit assembly, the reliability of device is strengthened greatly; Because control part adopts controlling spring, makes this device to different road surface reaction sensitivities, can not cause control part to lose efficacy by invar silk fracture of rope, thereby make fuel feeding accurate; Owing to adopt the fine tuning valve that can make the gas passage size variation, make this device strong to the comformability of different automobile types and vehicle condition; Because this apparatus structure is simply compact, be easy to install and use simultaneously.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a upward view of the present utility model.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is the view of speed governing cover 13.
Fig. 5 is the lateral plan of Fig. 4.
Among the figure 1, flexible axle, 2, air intake branch, 3, piston rod, 4, left end cap, 5, housing, 6, gas channels, 7, big piston, 8, screw pin, 9, speed control cylinder, 10, calibrated disc and knob assembly, 11, the electromagnetic valve assembly, 12, right end cap, 13, speed governing cover, 14, pressure cap, 15, screw pin, 16, needle-valve, 17, swivel nut, 18, controlling spring, 19, valve piston, 20, the fine setting cylinder, 21, the installation site.
The negative pressure variation that produces in the air inlet pipe when the utility model utilizes internal combustion engine is controlled the engine oil amount.The variation of fine setting cylinder induction negative pressure and according to changing the automatically regulating delivery quality; The speed control cylinder is that the adjustment speed of a motor vehicle is the power cylinder of engine behavior.The air intake branch of fine setting cylinder, speed control cylinder sending and receiving motivation, the speed control cylinder is controlled by air-operated solenoid valve.Set the stroke of speed control cylinder with the speed governing knob after, open master cock, electromagnetic valve is connected the vacuum of speed regulation cylinder, and the speed control cylinder spurs the controlling spring of fine setting cylinder under the negative pressure effect, and controlling spring promotes the control cylinder piston and promptly pushes up or draw back throttle to engine oil.When controlling spring promotes control plunger, must overcome the negative pressure of piston, only during greater than the negative pressure of piston, could promote piston and remove to open throttle, so in spring promotion piston, spring have a predetermincd tension at initial tension of spring.The speed control cylinder runs to desired location, and fine setting cylinder piston makes driving engine be stabilized in a certain rotating speed, negative pressure and initial tension of spring balance that this moment, the control cylinder piston bore under the application force of spring.When automobile went up a slope, load increased, and engine speed reduces, and negative pressure reduces, and initial tension of spring is greater than the negative pressure that piston bore, and spring drive piston is opened large throttle increases delivery quality; Engine load alleviates during descending, and rotating speed improves, and the negative pressure that piston bears is greater than initial tension of spring, and spring is further compressed by piston and reduced delivery quality, reaches the purpose in the stable control of the certain slope scope speed of a motor vehicle.
For making this device realize that people's one machine from running-fit, respectively is equipped with master cock on autoclutch and brake pedal, gear shift or when braking disposition, the vacuum work state of solenoid valve shuts speed regulation cylinder.Changed shelves release the clutch pedal or handle the situation loosen the brake, electromagnetic valve is connected the vacuum source of speed regulation cylinder, and car is transferred to the former setting speed of a motor vehicle travels, and has realized gear shift or the man-machine cooperation when braking disposition when operation.
This device and accelerator rod are carried out to separate and are connected, under the auto-supply state, but manually still step on the accelerator improve speed, unclamp the throttle automobile and be in the auto-supply state.The speed of shunting only needs rotation speed governing knob just can realize.
