Abstract
The invention relates a linear electromagnetic normally-closed valve of an automobile braking system. The linear electromagnetic normally-closed valve of the automobile braking system comprises a plunger tube, a fixed iron piece, a spring, a movable iron component, a flange, a valve seat, a ring filter screen and a steel ball, and the movable iron component is formed by a push rod and a valve body and is capable of axially move inside the plunger tube. The spring is installed inside the fixed iron piece, the fixed iron piece and the movable iron component are connected through the spring, the fixed iron piece and the plunger tube are fixedly connected, the valve seat and the plunger tube are connected together in a welding mode, and the spherical surface tip portion of the push rod and the conical surface of the valve seat are in sealable contacting connection. The linear electromagnetic normally-closed valve of the automobile braking system with the structure can achieve linear control.
Description
Technical field
The present invention relates to a kind of brake system of car linear electromagnetic normally close valve.
Background technique
Traditional use for brake system normally close valve has generally adopted the electromagnetic valve structure of bi-bit bi-pass, by the power on/off of coil, controls the Push And Release of solenoid valve.In traditional ABS system, normally close valve is as reduction valve, when pressure of wheel braking cylinder is too high, reduces rapidly in order to make pressure, usually direct normally close valve can be opened fully, with the purpose that obtains reducing pressure.The aperture of valve port is subjected to the impact of these four kinds of power of electromagnetic force, hydraulic power, damping force and frictional force, during due to decompression, the flow direction of brake fluid is to leave the opposite direction of valve port with push rod, and traditional like this normally close valve structure can not realize valve port is accurately controlled, i.e. linearity control.Yet, along with the development of braking system technology, all require when reducing pressure in the technology such as ESC, braking energy recovery, also can control accurately pressure.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of brake system of car linear electromagnetic normally close valve, by changing the structure of solenoid valve, realizes the linearity control of normally close valve.
for solving the problems of the technologies described above, the invention provides a kind of brake system of car linear electromagnetic normally close valve, comprise plunger tube, decide iron, spring, moving iron component, flange, valve seat, the ring filter screen, steel ball, described moving iron component is comprised of push rod and valve body, described push rod is pressed into described valve inner by interference fit, it is fixedly connected with, described moving iron component can move vertically, to decide iron inner described for described spring fitting, describedly decide between iron and described moving iron component to connect by described spring, describedly decide iron and be fixedly connected with described plunger tube, described valve seat and described plunger tube are by being welded together, it is characterized in that:
The tip of described push rod is spherical shape, is that salable contact is connected with the valve port conical surface of described valve seat.
As preferably, from the direction of the assembling of valve, the liquid entering hole position of described linear electromagnetic normally close valve is below described valve port.Like this, realized that the flow direction of brake fluid is identical with the direction that push rod leaves valve port.
As preferably, it is characterized in that, the liquid outlet of described linear electromagnetic normally close valve is in described valve seat bottom.Identical with the liquid outlet position of traditional normally close valve, avoided redesigning the work of original line arrangement.
Solenoid valve of the present invention by having changed the structure of the structure of solenoid valve, particularly valve seat, has changed the flow through direction of normally close valve of brake fluid, has realized the linearity control of normally close valve.
Description of drawings
Below in conjunction with the drawings and specific embodiments, technological scheme of the present invention is further described in detail.
Fig. 1 is the main sectional view under off-position of the present invention.
Fig. 2 be of the present invention under off-position the sectional view along A-A.
Embodiment
As shown in Figure 1, the linear electromagnetic normally close valve comprises plunger tube 1, decides iron 2, spring 3, moving iron component (moving iron 4 and push rod 5), flange 6, valve seat 7, ring filter screen 8, steel ball 9.Push rod 5 is pressed into the inside of moving iron 4 by interference fit, form moving iron component, can move axially in plunger tube 2.Spring 3 is packed into and is decided iron 2 inside, decides iron 2 and is connected with moving iron component by spring 3, and spring 3 has certain pretightening force.Moving iron 2 is pressed in plunger tube 2 by interference fit, and is fixing by riveting method 12, and anti-stop iron is play up and down.Valve seat 6 is fixing by laser bonding () with plunger tube 2.Under the state of outage, push rod 5 sphere tips 13 are connected for salable contact with the conical surface 14 of valve seat 6, Here it is so-called normally close valve.Steel ball 9 is blocked the auxiliary hole 15 of valve seat 6.
When needs reduce pressure, electromagnetic valve coil is electricity bitterly, brake fluid is through ring filter screen 8, enter the inlet opening 10 of valve seat 6, at this moment, will lift off a seat 7 the conical surface 14 of push rod 5, valve port will be opened, brake fluid enters the pit of valve seat 7 through the conical surface 14, then flows out solenoid valves by the liquid outlet 11 that leads to the valve seat bottom as shown in Figure 2.Such normally close valve structure can be controlled the poor variation of solenoid valve inlet and outlet pressure by the variation of controlling electric current, thereby realizes the linearity control to pressure of wheel braking cylinder.
It should be noted last that, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although with reference to preferred embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technological scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
