Description
Technical field
The utility model relates to a kind of anti-block braking system of car normally closed solenoid valve, belongs to automobile brake electromagnetic valve technical field.
Background technology
As everyone knows, experienced driver, when being everlasting drag, phenomenon such as the sideslip that produces when taking that the braking method that pedal one is stepped on a pine prevented the automotive wheel locking, whipping.And anti-block braking system of car (hereinafter to be referred as ABS) can realize automatically successfully that this steps on the automobile brake form of a pine.
At present, popular in the world ABS though multiple version is arranged, all has three parts of sensor, electronic control package (ECU) and hydraulic control device (HCU) to form, form mechanical, electrical, hydraulic pressure is integrated, thereby reach wheel not by locking phenomenon.The hydraulic efficiency governing principle of ABS is to be provided with a normally open solenoid valve and a normally closed solenoid valve at each wheel, and their series connection are used in hydraulic tubing.When normal brake application, ABS no power, the pressure of brake system master cylinder directly enter brake cylinder by the brake system master cylinder through normally open solenoid valve.When wheel lockup is critical, sensor sends signal, ABS gets electric work, this moment, electromagnetic valve divided three kinds of service conditions: (1) normally open solenoid valve becomes and ends, the normally closed solenoid valve no power also becomes to end, then the pressure between brake cylinder and brake cylinder master cylinder and the backwash pump is isolated, and promptly the brake-pressure in the wheel cylinder keeps; (2) normally open solenoid valve becomes and ends, normally closed solenoid valve energising becoming conducting, and the braking liquid in the wheel cylinder flows into energy storage and backwash pump by outlet valve, and the brake-pressure in the wheel cylinder reduces, backwash pump work, braking liquid is sent master cylinder back to; (3) normally open solenoid valve outage becoming conducting, normally closed solenoid valve cuts off the power supply for becoming and ends, and this is consistent with normal brake application, the brake-pressure increase in the wheel cylinder.
Connect fixingly between the valve seat of existing normally closed solenoid valve and the valve body by gland and orienting sleeve,,, have defectives such as complex process, element precision requirement height, difficulty of processing are big because parts are more on its structure design though have the better seal effect.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and compact conformation is easy to process, can effectively improve the anti-block braking system of car normally closed solenoid valve of normally closed solenoid valve service life and safe reliability.
The utility model is the anti-block braking system of car normally closed solenoid valve, comprise valve body, place the valve seat of being with valve port and braking liquid passage in the valve body, it is characterized in that valve body connects for extruding with valve seat, the valve body outside is provided with the normally open solenoid valve interface of band filter screen, and valve body lower end is provided with the lower end filter screen, and valve body top is provided with moving iron core, moving iron core top is provided with the static iron core of band valve rod and retracing spring, and valve rod passes moving iron core vertically downward.
Described moving iron core and static iron core also can coat plunger tube outward, and are connected into one with the valve body extruding.Also can be provided with antifreeze plate between described moving iron core and the static iron core.Also can offer annular groove on the described static iron core, plunger tube is squeezed into the annular groove internal strain of static iron core and fixes.
After can adopting riveted joint, described moving iron core and valve rod join together.
The utility model adopts extrusion process and high fix with valve seat and valve body, gland and two parts of orienting sleeve in the existing normally closed solenoid valve have been reduced, reasonable in design, easy to process, and make integral structure compact more, can guarantee the requirement of its right alignment, increase the rigidity and the stability of valve rod and valve base sealing again, thereby improve the service life and the safe reliability of normally closed solenoid valve.The supporting use of the utility model and anti-block braking system of car (ABS) can prevent effectively that automobile from glancing impact, whipping occurring, breaks away, and drives dangerous phenomenon such as skid, and guarantees road-holding property and shortens stopping distance.
Description of drawings
Fig. 1 is the integral structure cutaway view of existing normally closed solenoid valve;
Fig. 2 is a whole sectional structure chart of the present utility model.
Among the figure: 1 is plunger tube, and 2 is static iron core, and 3 is retracing spring, 4 are moving iron core, and 5 is valve body, and 6 is valve seat, 7 is the braking liquid passage in the valve seat, and 8 is the energy storage interface, and 9 is the lower end filter screen, 10 is valve port, and 11 are the ring filter screen, and 12 is the normally open solenoid valve interface, 13 is valve rod, and 14 is antifreeze plate, and 15 is the annular groove on the static iron core, 16 is orienting sleeve, and 17 is gland.
The specific embodiment
The utility model is mainly by valve body 5, place the valve seat 6 of static iron core 2, valve rod 13, retracing spring 3, antifreeze plate 14, moving iron core 4, band valve port 10 and the braking liquid passage 7 of the band connected in star 15 that sets gradually in the valve body 5 from top to bottom, place the normally open solenoid valve interface 12 of valve body 5 one side band filter screens 11, place lower end filter screen 9 formations such as grade of valve body 5 lower ends.Valve seat 6 adopts extrusion process to connect with valve body 5, has the constructional feature of no leak, and has reduced gland 17 and 16 two parts of orienting sleeve (as shown in Figure 1) that are used to connect fixed valve body 5 and valve seat 6 in the existing normally closed solenoid valve.Valve rod 13 is connected into one after adopting riveted joint with moving iron core 4, and passes moving iron core 4 vertically downward.Moving iron core 4 is connected into one with static iron core 2 outer coating plunger tubes 1 and with valve body 5 extruding, and plunger tube 1 upper compressive is gone into annular groove 15 internal strains of static iron core 2 and fixed.Braking liquid passage 7 in the valve seat 6 is connected with energy storage interface 8.
When routine was moved, because the effect of retracing spring 3, the valve port 10 on the valve seat 6 was closed with valve rod 13, and this moment, the master cylinder brake-pressure was more than or equal to a minute pump pressure; When brake off, because the effect of normally open solenoid valve, braking liquid refluxes, and reduces rapidly and divides pump pressure, until consistent with master cylinder pressure.
When ABS works, under the electromagnetic force effect, move on the valve rod 13 servo-actuated iron cores 4, valve port 10 on the valve seat 6 separates with valve rod 13, valve port 10 is opened, and the braking liquid in the wheel cylinder flows into energy storage and backwash pump through energy storage interface 8, and the brake-pressure in the wheel cylinder reduces, backwash pump work, braking liquid is sent master cylinder back to.
