Five, embodiment
Be described further below in conjunction with the implementation process of accompanying drawing the automobile auxiliary brake solenoid valve agent structure of a kind of Highgrade integration of the utility model:
(1) manufacture process: manufacture process is formed with the general assembly process by assembly is integrated.
(1). assembly is integrated: at first will process plunger tube 1.2, be injection molded into coil rack 1.4 as insertion, then on the coil rack 1.4 around on electromagnetic coil 1.3, and the metal insert 1.6 of burn-oning, electric device 1.7 and yoke 1.5 are injection molded into coil block 1 once more.Be static iron core assembly 2 to the riveted joint of Component such as metal shell 2.1, static iron core 2.2, pad 2.3, plastic housing 2.4 then.
(2). the general assembly process:
The elastomer 3.2 of moving core assembly 3, lower end cover compression spring 3.3, then; With pack into the endoporus of static iron core 2.2 of static iron core assembly 2 of stage clip 3.3 the other ends; Again coil block 1 inner chamber is inserted in moving iron core 3, profile is inserted in the metal shell 2.1 of static iron core assembly 2, makes stage clip 3.3 pressurizeds; Yoke periphery riveted making on the special plane on metal shell 2.1 upper ends and the coil block 1 becomes the agent structure of the automobile auxiliary braking of a kind of Highgrade integration of the utility model with solenoid valve.Then with filter screen 6 filter screen seat 7 of packing into, and with inner bag 8, inner housing 10 is put into successively, at last filter case is wedge pressed into through its card in the ring wedge mouth of outer cover 9 of static iron core assembly 2, and general assembly is accomplished.
(2) using process:
Energized, coil excitation produces magnetic field, and the magnetic line of force forms magnetic loop along static iron core 2.2, electromagnetism air gap delta, moving iron core 3.1, plunger tube 1.2, yoke 1.5, metal shell 2.1, pad 2.3, static iron core 2.2; Because the effect of magnetic force, moving core assembly 3 overcomes the resistance of stage clip 3.3, crosses the electromagnetism air gap; Attracted by static iron core 2.2; Therefore, elastomer 3.2 lower flange of moving iron core 3.1 dumbbell shapeds cover the suction port of static iron core 2.2, have sealed the plasmas channel that is got into by solenoid valve below filter.At this moment, coil block 1 overdraught passage I, II are communicated with, and cut off with III; Pressure is directly delivered in the connected auxiliary brake servo-cylinder of the left II (not shown); Servo-cylinder is closed the high-temperature gas that comes out from gas exhaust manifold through a series of actuators, and engine exhaust is obstructed, and rotating speed descends rapidly; Engine power reduces, and reaches the usefulness of braking; Otherwise when cutting off the electricity supply, magnetic field disappears; Moving core assembly 3 is under stage clip 3.3 reposition force effects, and moving core assembly rises, and the electromagnetism air gap produces; Dumbbell shaped elastomer 3.2 upper-end surfaces of moving iron core 3.1 are sealed and are moulded system housing 1.1 air communication road junction vertically downward, have cut off I, II left and right sides passage, and II, III are communicated with; The off-load of auxiliary brake actuator is resetted, and the outlet pipe of automobile and suction tude are recovered normal exhaust and air inlet, automobile normal running.
