Description
Technical field
The utility model belongs to the vehicle motor field, relates to a kind of high pressure common rail injector, specifically a kind of armature assembly of high pressure common rail injector.
Background technology
Along with the whole vehicle emission level improve constantly and more and more higher to the requirement of VE Vehicle Economy, engine low noise, from automobile national Ⅲ emission code enforcement, high pressure co-rail system is used widely at Diesel engine or electric injection gasoline engine.
High pressure co-rail system is comprised of high-pressure oil pump, common rail pipe, fuel injector, high-pressure oil pipe, transducer, actuator, electronic control unit (ECU) etc.Fuel injector is most critical and the most complicated parts in the high pressure co-rail system, it comprises the assemblies such as electromagnetically operated valve, spring, armature, steel ball briquetting, needle-valve, oil atomizer, effect is the control signal of sending according to ECU, by the opening and closing of control electromagnetically operated valve, the fuel oil in the high pressure oil rail is sprayed into the combustion chamber of engine with injection timing, distributive value and the fuel injection rate of the best.Armature is comprised of armature plate, armature core between spring and steel ball briquetting, and the armature core is provided with boss, and armature plate is pressed into to boss from armature core upper end, then armature core and armature plate is welded together in boss and armature plate contact site.During the electromagnetically operated valve no power, armature is subject to the spring applied pressure, during the electromagnetically operated valve energising, armature overcomes initial tension of spring and is lifted under the effect of electromagnetic attraction, in this process, the welding position can be subject to electromagnetic attraction, the phenomenon that causes the welding position to be prone to snapping, make the armature operational failure, and then affect the fuel injector normal operation.
The utility model content
For solving above shortcomings in the prior art, the utility model provides a kind of armature assembly of high pressure common rail injector, by changing the welding position of armature core and armature plate, the phenomenon that occurs snapping when avoiding the armature assembly to be subject to electromagnetic attraction, and the reliability that guarantees its welding manner is high, simple and practical, be fit to produce in enormous quantities.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of armature assembly of high pressure common rail injector, comprise the perpendicular cylindricality armature core of putting, the horizontal armature plate with vertical height, armature plate is placed in the armature core outward and the two is the cross cooperation, the armature core with the armature plate joint with the boss that extends radially outward, boss contacts with armature plate, and armature core and armature plate connect firmly in the welding of the position, non-boss place of the two touching position.
As to restriction of the present utility model, described armature plate top be provided with the groove suitable with boss with the contacted position of armature core, boss is positioned at groove;
Be used for the welding position that armature core and armature plate connect firmly, be the position that contacts with the armature core bottom the armature plate.
As another kind of the present utility model is limited, described boss is the stereochemical structure around armature core circumferential closure with vertical height.
As to further restriction of the present utility model, described armature core, armature plate, boss are coaxially set.
The utility model also has a kind of restriction, the overall structure that described boss and armature core are formed in one.
Owing to adopted technique scheme, the utility model compared with prior art, obtained technological progress is:
When electromagnetically operated valve was switched on, the top of armature plate was subject to electromagnetic attraction, made the armature assembly overcome initial tension of spring and was lifted.The utility model is by changing the welding position of armature core and armature plate, and the welding position is avoided or away from the top of armature plate, the phenomenon that occurs snapping in the time of can avoiding the armature assembly to be subject to electromagnetic attraction, thus guarantee the fuel injector normal operation.
In sum, the utlity model has and be welded and fixed reliably, simple and practical, be fit to the characteristics of producing in enormous quantities.
The utility model is applicable on the various high pressure common rail injectors.
Description of drawings
Below in conjunction with drawings and the specific embodiments the utility model is done further to describe in detail.
Fig. 1 is the schematic diagram of the vertical profile structure of the utility model embodiment;
Fig. 2 is that the utility model embodiment is assemblied in the overall structure sectional side elevation on the fuel injector.
Among the figure: 1, armature core; 2, armature plate; 3, boss; 4, welding position; 5, spring; 6, electromagnetically operated valve.
Embodiment
Embodiment
A kind of armature assembly of high pressure common rail injector, structure comprise armature core 1, armature plate 2 as shown in Figure 1.
The main body of armature core 1 is perpendicular put cylindrical, on its outer wall with the integrated boss that extends radially outward 3 of main body.Armature core 1, armature plate 2 and boss 3 are coaxially set.Boss 3 is the rotary structure take this axis as gyroaxis, and it is in vertically having height.
The main body of armature plate 2 is the rotary structure with vertical thickness, and the radial section of this main body is circular.Its top is provided with the groove that is complementary with boss 3.During assembling, armature plate 2 upwards is pressed into to boss 3 places by armature core 1 lower end, makes boss 3 be positioned at groove fully, and armature plate 2 is decussate texture with the integral body of armature core 1.2 of armature core 1 and armature plates adopt welding to connect firmly, and welding position 4 is armature plate 2 bottoms and armature core 1 contacted position.
The present embodiment course of work following (with reference to figure 2):
During electromagnetically operated valve 6 no power, fuel injector is not worked, and the armature assembly is subject to spring 5 applied pressures.
During the energising of electromagnetism 6 valves, produce electromagnetic attraction, the top of armature plate 2 is subject to electromagnetic attraction, making the armature assembly overcome spring 5 pretightning forces is lifted, because welding position 4 is positioned at the bottom of armature core 1 and armature plate 2 contacts site, avoided the position at armature plate 2 tops, thus the phenomenon that occurs snapping when avoiding the armature assembly to be subject to electromagnetic attraction.
