Description
Technical field
The utility model relates to a kind of jerk pump, and especially a kind of electronic control dispensing pump fuel feeding controlling mechanism belongs to automobile accessories spare technical field.
Background technique
Understand according to the claimant, the fuel feeding controlling mechanism that is provided in the mechanical type VE type proportioning pump on the existing vehicle as shown in Figure 1, comprise the speed governing axle 1-1 that is fixed on the pump housing 10, be enclosed within driven small gear 1-2 on the speed governing axle 1-1, fixedly connected with driven small gear 1-2 fly block 1-3, be contained in four of flying in the block 3 fly piece 1-4 for a short time, be enclosed within Thurst washer 1-5 and the speed governing sliding sleeve 1-6 on the speed governing axle 1-1 and be contained in speed governing sliding sleeve 1-6 end chock plug 1-7, speed-regulating rack parts 1-8, be enclosed within fuel-flow control cover 9 compositions on the plunger.The working principle that this fuel feeding is regulated system is: when motor drove transmission shaft 11 rotations by gearwheel, on the one hand, the driving gear on this was delivered to driven small gear 1-2 with rotation, flew piece for a short time and rotated thereupon thereby drive four of flying in the block; On the other hand, the end cam 12 of this termination will order about in rotary course and distribute plunger 13 to-and-fro motion, thereby realize the supply of fuel oil.In this process, when vehicle is in different applying working condition, the throttle position engine speed that changes changes, increase or the centrifugal force that reduces to fly piece increases thereupon or reduces with rotating speed, fly that piece opens thereupon or closed, thereby increase or reduce by flying strength that the piece leg promotes Thurst washer, and then increase or reduce by the strength that speed governing sliding sleeve and chock plug promote the speed-regulating rack parts, it is rotated around fulcrum, the result will drive control by bulb and be enclosed within and distribute on the plunger to the right, to shifting left, the control cover to the right, changed the relative position in the draining hole 17 on the distribution plunger of controlled cover shutoff in the process of shifting left, the result has realized that fuel delivery increases or reduces.
Raising along with automobile exhaust emission standard, especially the issuing and implementation of state III Abgasgesetz, above-mentioned existing VE type pump proportioning pump is because the accurate supply of fuel delivery relies on mechanical governor control, validity is low, each operating point can not be realized the Flexible Control of fuel delivery, promptly accurately adjust fuel delivery in good time, so do not reach state III emission standard after the entrucking energy-conservation and environmental protection requirement according to the system feedback test parameter.
The model utility content
The utility model wants the technical solution problem to be: at the problem of above prior art existence, propose a kind ofly can adjust the electronic control dispensing pump fuel feeding controlling mechanism of fuel delivery in good time accurately, thereby reach state III emission standard energy-conservation and environmental protection requirement according to the system feedback test parameter.
In order to solve above technical problem, electronic control dispensing pump fuel feeding controlling mechanism of the present utility model comprises the transmission shaft that is installed in pump housing two ends respectively and is parallel to each other and distributes plunger; End cam is equipped with in the inner of described transmission shaft; Described distribution plunger one end is resisted against on the end cam, and its position that is positioned at the pump housing is shaped on the draining hole, described draining hole one side suit control sleeve; Described fuel-flow control puts and is shaped on the ball pivot hole; Be equipped with on the described pump housing drive motor and with distribute the vertical core axis of plunger, the lower end of described core axis is shaped on cam pin, the lower end of described cam pin forms the bulb that constitutes typed ball bearing pair with described ball pivot hole; Described core axis is fixedlyed connected with described drive motor rotor.
Like this, according to the system feedback test parameter, by the rotation of controlling and driving motor, get final product the pivotal position of drive controlling core axis lower end cam pin, thereby make the relative draining of control sleeve hole be in the desired position by typed ball bearing pair, reach the purpose of control dredge oil amount, realize the regulation and control of fuel delivery.Understand easily, this obviously more accurate than the centrifugal control of above-mentioned traditional mechanical formula by automatically controlled regulation and control, therefore reach state III emission standard easily.
The utility model further improves: the angle transducer that the signal output part connection control circuit is housed on the described core axis.Therefore, control circuit can be realized closed loop control to the corner of core axis, thereby makes the regulation and control of fuel delivery more accurate.

Embodiment
Embodiment one
The electronic control dispensing pump fuel feeding controlling mechanism of present embodiment as shown in Figure 1, an end of the pump housing 10 is installed transmission shaft 11, the plug-in mounting distribution plunger 13 coaxial with transmission shaft in the plunger bushing of the other end.End cam 12 is equipped with in the inner of transmission shaft 11, distributes the left end of plunger 13 to be resisted against on the end cam, therefore when transmission shaft rotates, can order about by end cam and distribute the plunger to-and-fro motion, realizes the supply of fluid.The position of distributing plunger 13 to be positioned at the pump housing is shaped on draining hole 17, and this draining hole one side suit is shaped on the control sleeve 6 in ball pivot hole.
The drive motor that is made of stator 3 and rotor 2 is equipped with on the top of the pump housing 10, with the vertical core axis 8 and rotor 2 coaxial fixedlying connected of distribution plunger, the middle part is inserted on the pump housing 10, the lower end is shaped on axle position shoulder block, stretch out the frustoconic shape cam pin of dribbling 1 under the shoulder block of axle position, the ball pivot hole formation typed ball bearing pair on this bulb and the control sleeve 6.Therefore, when drive motor drives the core axis transposition, the bulb of cam pin will drive fuel-flow control and be enclosed within the axial position that distributes on the plunger, thereby change the draining situation of draining hole in distributing plunger to-and-fro motion process as required, to reach the purpose of control fuel delivery.
In order to realize more position accurate closed loop control, the upper end of core axis 8 and the angle transducer 4 that the signal output part connection control circuit is housed.Like this, can monitor the angle position of core axis 8 in real time, thereby further guarantee to realize control up to standard.In addition, 5 among the figure is Returnning springs, the 6th, and oil spilling ring, the 7th, coil.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to replaces the technological scheme that forms, and all drops on the protection domain of the utility model requirement.
