Description
Technical field
The utility model relates to the electronic controlled carburetor technical field, refers in particular to the general electronic control carburetor electromagnetic valve of a kind of state-of-the art automobile and motorcycle and all motor vehicle and improves structure.
Background technique
In the Carburetor electric control device (or claiming the electronics making-up air device) of automobile and motorcycle, solenoid valve is the power unit of nuclear core, controller ECU in this control gear exports control signal to solenoid valve, control electromagnetic valve is opened, the dutycycle of shut-in time, realizes Carburetor is opened the control of air mass flow thus.The concentration that is to say the mixed gas that automobile or motorcycle carburetor are provided is controlled, and makes motor realize good burning, thereby effectively reduces oil consumption and reduce noxious emission.
Because control gear sends the control command of open and close duty ratio of time to solenoid valve, thereby requires solenoid valve that very high frequency of okperation and speed of response will be arranged along with the operation of motor changes in good time, require lower operational noise again.And the present low noise that the solenoid valve of the former preparation of this control gear is required, driving force, aspects such as sensitivity, reliability are all not ideal enough.Now can solve the problems referred to above by the moving surely core structure that in electromagnetic valve body, cooperatively interacts.But, the design of original solenoid valve, material and manufacturing process thereof be the extensive operation of this series products of incompatibility also, the cost height, manufacturing efficiency is low.For example, because the motion speed of moving iron core is fast in the solenoid valve, the frequency of okperation height, general soft iron material such as electrical pure iron or low carbon steel are done the iron core serious wear, and operating temperature is very high, the easy oxidation of long-term work and getting rusty, thereby in the past can only be with containing the chromium magnetically soft alloy material or claiming soft-magnetic stainless steel to do core material, promptly wear-resisting non-corrosive again.But contain the chromium magnetically soft alloy material and also have its defective, promptly material expensive is not easy cutting again very much, is difficult to go up automatic lathe and goes into operation the manufacture cost height in enormous quantities.
Summary of the invention
At above shortcomings on the original design of existing electronic control carburetor electromagnetic valve, material and the structure thereof, the utility model proposes the general electronic control carburetor electromagnetic valve of a kind of up-to-date improved automobile and motorcycle and all motor vehicle and improve structure, so that the extensive operation of this product, and reduce manufacture cost significantly, enhance productivity, significantly improve the working life of product, reliability and performance.
For achieving the above object, the utility model includes: electromagnetic driver and valve body, and electromagnetic driver is by shell, soft iron frame, line bag, coil frame and be positioned at intraskeletal fixed core and moving iron core is formed; Valve body comprises valve seat and rubber valve pad, the other end of copper valve seat is fixed with the stainless steel sleeve pipe that holds moving iron core, stainless steel sleeve pipe and fixed core are mounted in the coil frame, and an end of moving iron core is fixed with the rubber valve pad, have covered one deck nitriding layer at the outer surface that moves iron core.
The moving iron core that machine shaping is good is carried out surface carburization processing or nitrogen and other element mixing osmosis process processing, carry out polishing treatment then, moving iron core surface hardness after the nitriding improves greatly like this, its hardness substantially exceeds and contains the chromium magnetically soft alloy material, very wear-resisting, not only do not influence the magnetic property that moves iron core, and performance is better, sensitivity is higher, simultaneously again can be antirust.Therefore the material of moving iron core can be eliminated the expensive chromium magnetically soft alloy material that contains, and adopts especially sulfur-bearing low carbon steel of the electrical pure iron of considerably cheaper or low carbon steel.And the light pole material of electrical pure iron or sulfur-bearing low carbon steel is convenient to automatic lathe and is gone into operation in enormous quantities very much.Cost of raw and manufacture cost have lowered significantly like this.Fixed core also adopts electrical pure iron or the manufacturing of sulfur-bearing low carbon steel, after machine shaping is anti-truncated cone shape or cylinder type, and nickel plating or zinc-plated to improve degree of finish and antirust.
In addition, otherwise improvement also has: the moving iron core of the solenoid valve of moving iron core, the especially high-powered car of solenoid valve, must open dredging flow groove or current by pass.Resistance of air so that remarkable minimizing high-speed motion produces improves solenoid valve speed of response and sensitivity.Nitriding processing or nitrogen mix infiltration with other elements before, as required, but moving iron core machine shaping is spun tapered or is spun awl and cylinder hybrid type for what is complementary with anti-truncated cone shape fixed core, but perhaps machine shaping is cylinder type or the dumbbell shape that is complementary with the cylinder type fixed core.
After adopting said structure, the driving force of the utility model solenoid valve, working sensitivity, speed of response and reliability obviously improve, and noise lowers greatly, and fuel-economizing and discharging all are significantly improved.The fuel saving ratio of automobile and motorcycle all can reach more than 15% after tested, and discharging all can reach No. two standards in Europe, near No. three standards in Europe.Transformation to new car is expected to reach No. three standards in Europe.
