Description

The electronic control carburetor electromagnetic valve that motor vehicle are general

Technical field:

The utility model relates to the electronic controlled carburetor technical field, refers in particular to a kind of state-of-the art automobile and motorcycle and the general electronic control carburetor electromagnetic valve of all motor vehicle.

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 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.

Summary of the invention:

At existing electronic control carburetor electromagnetic valve above shortcomings, the utility model proposes a kind of up-to-date improved automobile and motorcycle and the general electronic control carburetor electromagnetic valve of all motor vehicle, to improve the sensitivity and the speed of response of solenoid valve, reduce noise, reduce the discharging of harmful gas and material, save fuel oil.

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 unshakable in one's determination the composition; 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, one end of moving iron core is fixed with the rubber valve pad, one end of fixed core forms the cavity that is anti-truncated cone shape, the lapped pipe end of stainless steel sleeve pipe is screwed onto copper valve seat one end by copper sheathing, be provided with rubber buffer ring and Returnning spring between moving iron core in the stainless steel sleeve pipe and the fixed core, the copper valve seat has one suction port, external suction tude perhaps adopts four equally distributed inlet holes.

After adopting said structure, the electromagnetic driver of the utility model solenoid valve and valve body are connected and fixed by the stainless steel sleeve pipe, compact structure, and volume is little.The tapered moving iron core and the fixed core of anti-truncated cone shape are spun in employing, perhaps adopt the moving iron core of ladder cylinder type, perhaps adopt the moving iron core that spins awl and cylinder hybrid type, and Returnning spring and rubber buffer ring be set between moving iron core and fixed core, and technical measures such as the line bag of particular design and coil frame, making its driving force, working sensitivity, speed of response and reliability improve, 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.

The fixed core structural representation of the anti-truncated cone shape of Fig. 2;

The moving core structure schematic representation of Fig. 3 ladder cylinder type;

Fig. 4 spins the moving core structure schematic representation of awl and cylinder hybrid type;

The erection drawing of the electronic control carburetor electromagnetic valve that Fig. 5 motor vehicle are general.

Embodiment:

Erection drawing embodiment below in conjunction with accompanying drawing 5 further specifies this solenoid valve.Illustrating each parts is respectively:

Copper valve seat 1 has some inlet holes around it, and the inlet hole of 4 ￠ 3-￠ 10mm is arranged usually, and the inlet hole of a ￠ 6-￠ 12mm is perhaps only arranged; To cover Stainless Steel Cloth or copper mesh on the inlet hole, with the dust in the filtered air.Rubber gasket 3, it is embedded in an end of moving iron core 5; Rubber buffer ring 2 and Returnning spring 4 are loaded between the moving iron core 5 and fixed core 6 in the stainless steel sleeve pipe 8, to reduce noise; And moving iron core 5, fixed core 6, M14 copper sheathing 7, stainless steel sleeve pipe 8, soft iron frame 9, line bag 10, coil frame 11, signal input lead 12, plastic casing 13, jump ring 14.

Copper valve seat 1 the other end is fixed with stainless steel sleeve pipe 8, and moving iron core 5 is loaded in the stainless steel sleeve pipe 8, and the other end of stainless steel sleeve pipe 8 is contained in the coil frame 11, and electromagnetic driver and valve body are combined as a whole.

Among Fig. 5, fixed core 6 and stainless steel sleeve pipe 8 be with latch mode or other modes, as: modes such as punching press connect, and insert in the endoporus of coil frame 11, with jump ring 14 chuckings.The lapped pipe end of stainless steel sleeve pipe 8 is connected on copper valve seat 1 one ends by M14 copper sheathing 7 nuts, and rubber buffer ring 2, Returnning spring 4 and moving iron core 5 are positioned at stainless steel sleeve pipe 8.Moving iron core 5 is important power units of solenoid valve, have and spin the tapered moving iron core and the fixed core of anti-truncated cone shape, perhaps adopt the moving iron core of ladder cylinder type or moving iron core such as Fig. 1 that awl and cylinder hybrid type are spun in employing, Fig. 2, Fig. 3, three types shown in Figure 4, but no matter adopt the moving iron core of that type, the fixed core type is constant, all is anti-truncated cone shape.Can be according to the type of customer requirement or the moving iron core 5 of vehicle selection.The external diameter of moving iron core 5 is ￠ 5-15mm, and length is 13-40mm, and working stroke is controlled at the 1.0-4.0mm scope, cylinder, and conical surface degree of finish requires more than the 1.6 μ m.

Line bag 10 and coil rack 11, the design of the drive coil of solenoid valve also are very important, and owing to our important improvement in this respect, the driving force of solenoid valve significantly increases, and sensitivity improves, and starting resistor reduces.The skeleton internal diameter of general drive coil is ￠ 6-20mm, and the enameled cable diameter is ￠ 0.10mm-0.60mm, and the number of turn is 500-2000Ts, highly is 30mm-80mm.

In order to lower the noise in the solenoid valve running, on the end face of the fixed core 6 that the fixed core 6 of solenoid valve and moving iron core 5 impact, embed rubber buffer ring 2, perforate is wanted at rubber buffer ring 2 centers, only at spinning tapered moving iron core, to other moving iron cores of two types, then rubber buffer ring center does not need perforate, bore dia is ￠ 2-8mm, thickness is 0.3-2.5mm, use the high strength glue bond, the noise of solenoid valve has had tangible reduction like this, reduces the wearing and tearing and the distortion of moving iron core 5 simultaneously greatly, improves reliability.

The design of the fixed core 6 of solenoid valve, general outer diameter is a ￠ 6-18mm scope, total length is between 10mm-40mm.
