Description
Technical field
The present invention relates to a kind of electromagnet assemblies for being mainly used for high pressure fuel injection device.
Background technique
With the increasingly exacerbation of greenhouse effects of the earth and problem of environmental pollution, various countries are to vehicle exhaust, especially diesel vehicle
Vent gas treatment requires increasingly to increase.Diesel engine is in order to reduce the discharges of the pollutants such as Nox, particulate matter, HC and CO, it is desired to fuel oil
Spraying system realizes that high pressure, multi-injection, distributive value and injection time are precisely controlled, particularly with multi-injection time with
Microsecond meter meets above-mentioned requirements and only electronic control technology is used just to be able to achieve, thus improve electric-control system response speed to close weight
It wants.The bottleneck for improving the response speed of electric-control system is to improve the response speed of actuator.There are two alternative technologies
Route, first is that using stacked piezoelectric crystal as the actuator of solenoid valve, the other is using high-speed electro-magnet as solenoid valve
Actuator, be in response to the characteristics of stacked piezoelectric crystal that speed is fast, technical difficulty is big, poor reliability, at high cost, high-speed electro-magnet
Although response speed it is slow compared with the response of stacked piezoelectric crystal, but still the task of achievable multi-injection, and high speed electricity
Magnet for stacked piezoelectric crystal advantage possessed by its technical difficulty, reliability, cost etc. by domestic and international fuel feeding
System generallys use.Nevertheless, the electromagnet of the prior art is at it since high-speed electro-magnet works under the conditions of high-temperature high-frequency
Response speed, heat dissipation, reliability, anti-leak etc. still have some defects and deficiency.The middle electromagnet assembly of the prior art, is usually adopted
With electromagnet shown in Fig. 2.The electromagnet specifically includes that an outer circle is stepped diameters and the concentric cavity with stepped diameters
Fixed electromagnet is played in the electromagnet housing 1 of cavity, the outside that fastening swivel nut 2 is mounted concentrically at electromagnet housing 1.Iron core
5 are mounted concentrically in 1 center cavity of electromagnet housing, lower end surface and electromagnet housing inner cavity step face contact, upper surface with it is interior
The lower plane of skeleton 12 contacts, by 1 upper end of magnet shell close up by iron core 5 be pressed on inner frame 12 and electromagnet housing 1 it
Between.After energization, there is electric current to flow through in coil 4, just produce magnetic field in iron core 5, the magnetic field pass through iron core 5 and armature 3 it
Between air-gap so that armature 3 obtain electromagnetic force Fm.The deficiencies in the prior art shown in Fig. 2 are that the lower end surface of iron core 5 is sat
It falls in the inner cavity seam allowance plane of electromagnet housing 1, the upper surface of iron core 5 is contacted with inner frame 12, passes through 1 upper end of electromagnet housing
Closing in compresses iron core 5, and result makes the outer cylinder of iron core 5 generate very big erection stress, the serious magnetic conduction for influencing iron core 5
Rate, so that the efficiency of electromagnet be made to substantially reduce.
The also deficiency of the above-mentioned prior art is that electromagnet will generate eddy current, coil sheet at work, in core interior
Body can also generate heat, if these heats cannot shed in time, will generate strong influence to the reliability of work of electromagnet, seriously
When can burn electromagnet, the iron core 5 of the prior art can only then flow into iron core by the fuel oil that the gap of armature and iron core is flowed through
Inner hole heat dissipation, since the gap between iron core 5 and armature 3 only has 0.1mm, and during armature motion, the gap is also
Continuous reduce causes the circulating resistance of fuel oil very big.The external cylindrical surface of iron core 5 there is no fuel oil to flow through, and in the iron core 5
The circulation area in hole only has the 13% of outer circle area, it is clear that only cannot get good heat dissipation effect by inner hole heat dissipation, therefore can be right
The reliability of electromagnet has an impact.
The third deficiency of the prior art is that the top of coil rack 6 and 5 groove of iron core does not have preset clearance, electromagnetism
When ironworker makees the coil and skeleton all can fever expansion, because of the space of the reserved expansion in upper end, the bottom surface of coil rack
It can only move down, the normal neutral plane of the coil and skeleton also moves down therewith, after electromagnet stops working cooling,
The coil and skeleton again can cooling meat, contraction at this time is no longer to revert to original position, but the both ends of the coil and skeleton
It bounces back simultaneously to its normal neutral plane, after electromagnet expands with heat and contract with cold repeatedly by long-term work, causes coil rack will be whole
It moves gradually downward, lower end surface will be also displaced gradually downward therewith, and the bottom surface of coil rack is once higher by the baseplane of iron core
Just will affect the work of electromagnet, can be dragged while more seriously the coil and skeleton move down pull conducting wire it is serious when will lead
Line, which is pulled apart, makes electromagnet fail.
4th deficiency of the prior art be, only one sealing ring 9, the sealing between inner frame 12 and shell 1
Circle belongs to extra small diametric seal, is easy to happen when pressure oscillation is larger because the connecting bar diameter sealed only has 1mm
Oil leak.
