Abstract
The utility model discloses a pipeline flow control valve between an auxiliary chamber and an air spring, which comprises a left end cover and a right end cover which are respectively provided with an inner cavity. The open end of the left end cover and the open end of the right end cover are respectively fixedly connected with a left orifice plate and a right orifice plate. The other end of the left end cover and the other end of the right end cover are respectively provided with a boss communicated with the inner cavity of each end cover. The right orifice plate is provided with four through holes b, c, e and f with bore diameters of different sizes and communicated with the inner cavity of the right end cover. The left orifice plate is provided with four through holes g with identical diameters and communicated with the inner cavity of the left end cover. One ends of four air pipes are respectively connected with the four through holes g, and the other ends are respectively communicated with the four through holes b, c, e, and f. An electromagnetic valve is correspondingly arranged at the position of each of the through holes b, c, e, and f. The electromagnetic valves are controlled to open or close according to requirements in order to control air flowage of a corresponding through hole and indirectly control air flowage area of the position between a main chamber and the auxiliary chamber, so as to change the damping of an air spring system. Multi-shift adjustment can be realized through a plurality of available combinations due to the fact that area of the through holes is different.
Description
Technical field
The utility model relates to the pipeline flow control valve between a kind of auxiliary chamber and pneumatic spring, and the airsuspension system that is specifically related to be used for vehicle is regulated the damping control valve of pipeline between pneumatic spring and the auxiliary chamber thereof.
Background technique
At present, changing the rigidity of the air spring system of being with auxiliary chamber and the method for resistance has three kinds: the one, and the volume size of the attached air chamber of change; The 2nd, change the damping that connects pipeline between main attached air chamber, the damping in the pipeline is mainly from the control valve in the pipeline.The 3rd, directly change the shape or the circulation area of pipeline.In the correlative study at home and abroad, also do not reported the device that can directly change the pipeline shape.
Summary of the invention
The purpose of this utility model provides the pipeline flow control valve between a kind of auxiliary chamber and pneumatic spring, can directly change the pipeline shape according to the working condition signal of vehicle, rationally regulates the circulation area of air between the main attached air chamber.
The technical solution adopted in the utility model is: comprise the left and right end cap that all has inner chamber, each fixedly connected left and right orifice plate of the opening end of left and right end cap, the other end of left and right end cap respectively has the boss that is communicated with its inner chamber, and right orifice plate is provided with and is communicated with right end cap 4 through hole b, c, e, f inner chamber, that pore size differs; Left side orifice plate is provided with 4 the identical through hole g of diameter that are communicated with the left end cap inner chamber; One end of 4 tracheaes connects 4 through hole g respectively, the other end connects 4 through hole b, c, e, f respectively, and each described through hole b, c, e, f place all correspondence are provided with a solenoid valve.
The utility model symmetrical configuration, the situation of closing by control electromagnetic valve realizes whether corresponding through hole has air ventilation according to demand, the switching that changes through hole gets final product the circulation area of air between the indirect attached air chamber of adjusting master, thereby change the damping of air spring system, because the area of through hole has nothing in common with each other, can there be multiple compound mode to realize the purpose that the many gears of flow control valve are regulated.

Among the figure: 1. left end cap; 2. left orifice plate; 3. tracheae; 4. solenoid valve; 5. right orifice plate; 6. right end cap.
Embodiment
Referring to Fig. 1, the utility model comprises left end cap 1 and right end cap 6, and left end cap 1 and right end cap 6 all have inner chamber, the fixedly connected left orifice plate 2 of the opening end of left end cap 1, the other end of left end cap 1 has the boss h that is communicated with its inner chamber, and pipe laying on boss h is used to be communicated with pneumatic spring.The fixedly connected right orifice plate 5 of the opening end of right end cap 6, the other end of right end cap 6 have the boss d that is communicated with its inner chamber, and pipe laying on boss h is used to be communicated with auxiliary chamber.
Referring to Fig. 3,4 through hole b, c, e, f are set on right orifice plate 5,4 through holes all are communicated with right end cap 6 inner chambers, and the pore size of these 4 through hole b, c, e, f differs, and radius is all inequality.In the specific implementation, consider the sealing between right end cap 6 and the right orifice plate 5, should be between right end cap 6 and the right orifice plate 5, between left end cap 1 and the left orifice plate 2 seal washer be installed all.
Referring to Fig. 2, also be provided with on the left orifice plate 2 and be communicated with left end cap 4 through hole g 1 inner chamber, that diameter is identical, arbitrary diameter of 4 through hole b, c, e, f is all less than the diameter of through hole g.Connect 4 tracheaes 3 between left side orifice plate 2 and the right orifice plate 5, one end of 4 tracheaes 3 connects 4 through hole g respectively, the other end of 4 tracheaes 3 connects 4 through hole b, c, e, f respectively, and each through hole b, c, e, f place all correspondence are provided with a solenoid valve 4, and each solenoid valve 4 all connects its driver.
Gas from pneumatic spring behind the utility model, the final path that arrives auxiliary chamber is followed successively by: pneumatic spring, pipeline, 1,4 through hole g of left end cap, tracheae 3, solenoid valve 4, tracheae 3,4 through hole b, c, e, f, right end cap 6, pipeline and auxiliary chambers, gas is the contrary path in above-mentioned path from the path that auxiliary chamber arrives pneumatic spring.
In the vehicle driving process, by the sensor driving cycle parameter of measuring vehicle (as pressure, vehicle body height etc. in vehicle driving acceleration, the pneumatic spring) constantly, sensor passes to ECU with the vehicle driving-cycle parameter that it records then, ECU compares computing with the standard that self stores to the received signal, after the processes such as the signal annular distribution of operation result signal process driver, power amplification, the closed condition of drive circuit control electromagnetic valve 4.Required tracheae circulation area operational equation when being solidified with the various operating mode of vehicle on the ECU, system is through the driving equation of the useful area of the through hole combination that relatively can select 4 through hole b, c, e, a f on the right orifice plate 5 close with operation result automatically, and the closed condition of change solenoid valve 4, whether control right orifice plate 5 through holes indirectly has gas communication.For example, if the sectional area of through hole b is 6
, the sectional area of through hole f is 20
, sensor passes to ECU with the vehicle driving-cycle parameter that records, and ECU is 25 according to the circulation area that the internal arithmetic equation calculates tracheae the best this moment
, the sectional area sum 6 of through hole b and through hole f
+ 20
=26
, near 25
, then ECU has selected the driving equation that the solenoid valve of valve opening solenoid, through hole a and the through hole d correspondence of through hole b and through hole c correspondence closes, and has finally realized more satisfactory tracheae circulation area adjusting.
4 through hole b, c of right orifice plate 5, e, f are always total
=16 kinds of composition situations, the pneumatic spring that offers of multiscale uses according to the actual requirements.Through hole number and size on the right orifice plate 5 are to redefine design according to the actual requirements.
