The controllable extensible vibration damper of the preferred embodiment of the present invention as shown in Figure 1, comprises that clutch release slave cylinder 10, oil storage cylinder 20, overcoat are firm 30, upper one-way valve 40, lower one-way valve 50, solenoid 60, lower solenoid valve 70, piston 80, piston rod 90 shock-absorbing spring 100 etc.
Wherein, composition graphs 1, Fig. 2 are known, and piston 80 adopts entity structure, and it does not establish damping hole, to be contained in clutch release slave cylinder 10 thus clutch release slave cylinder 10 to be divided into up/down cavity two parts.Piston 80 and clutch release slave cylinder 10 Spielpassung, ensure the sealing between clutch release slave cylinder inner carrier more than 80 and following upper and lower cavity, and that is, upper and lower two chambers of clutch release slave cylinder 10 are completely cut off and no liquid flowing by piston 80.Piston 80 lower end is connected with piston rod 90, and in the present embodiment as shown in Figure 1, piston 80 and piston rod 90 are structure as a whole.
The upper one-way valve 40 and the lower one-way valve 50 that are arranged on clutch release slave cylinder 10 top and low side respectively form by spring 43, sealing gasket 42 and gasket base 41, described gasket base 41 comprises column part and is positioned at the flange circle of flexible front end, sealing gasket 42 to be enclosed within column part and and have certain distance between flange circle, spring 43 is between sealing gasket 42 and flange circle.
Up/down solenoid valve 60/70 is equipped with in up/down one-way valve 40/50 outer end, and in the present embodiment, up/down solenoid valve 60/70 all adopts direct action solenoid valve, for being controlled the break-make of corresponding up/down one-way valve 40/50 by the control of electric current, thus controls the flow direction of oil.Herein with the structure of solenoid 60 for power explanation direct action solenoid valve.
Composition graphs 1, Fig. 3, Fig. 4 are known, and solenoid 60 comprises electromagnetic valve body 61, coil 62, coil rack 63, conducting magnetic column 64, end valve sealing cover 45 and solenoid valve sealing gasket 65.
Conducting magnetic column 64 is equipped with in sealing gasket 42 upper end of upper one-way valve 40, and in the present embodiment, conducting magnetic column 64 and gasket base 41 are as integrative-structure.On the circumferential outer surface of conducting magnetic column 64, cover has coil rack 63, coil rack 63 is wrapped coil 62.Coil 62 is peripherally equipped with columnar electromagnetic valve body 61.The upper-end surface of electromagnetic valve body 61 is equipped with solenoid valve sealing gasket 65, the center of conducting magnetic column 64 has shrinkage pool to place the spring of a connection solenoid sealing gasket 65 and conducting magnetic column 64.Under the action of the spring, normal lower spring is by solenoid valve sealing gasket 65 jack-up and keep certain distance between the upper-end surface of electromagnetic valve body 61, and work as solenoid valves, then solenoid valve sealing gasket 65 is adsorbed on electromagnetic valve body 61 upper-end surface.
As shown in Figure 2, Figure 3, Figure 4, electromagnetic valve body 61 has through hole 610 and the oil inlet hole 440 of up/down perforation, and the upper end of through hole 610 is sealed by sealing gasket 42, the solenoid valve sealing gasket 42 of upper end covers and is communicated with clutch release slave cylinder 10, oil inlet hole 440 is that lower end is sealed by sealing gasket 42, and solenoid valve sealing gasket 65 corresponding position of upper end has circular hole thus is communicated with oil storage cylinder 20.In order to ensure the free flow of liquid oil in solenoid valve, multiple through hole 610 and oil inlet hole 440 can be set, ensure that the flow of liquid oil is enough large, piston 80 be moved up and down be the liquid oil flow damping that causes enough little.
The air chamber that solenoid body 60 upper end has oil storage cylinder 20 top to be communicated with, this air chamber is for being assemblied in oil storage cylinder 20 top adapter ring 21 circumferentially and sealing by fastening bung flange 24 cavity that both upper end caps 23 of linking surround with adapter ring 21 upper end.When through hole 610 upper end of electromagnetic valve body 61 does not seal, be then directly communicated with air chamber, the upper end of oil inlet hole 440 then remains identical with air chamber.Ensure that the oil pressure in oil storage cylinder 20 is greater than clutch release slave cylinder 10, in necessary oil storage cylinder 20, liquid level is higher than clutch release slave cylinder 10 top, therefore a part of volume of air chamber is equipped with oil.As can be seen here, gas chamber volume must be greater than clutch release slave cylinder 10 volume-variation maximum flow.
When normally working, no current in coil 62 on conducting magnetic column 64, to reduce heating value, improves the operating life of solenoid 60, now, under the action of the spring, solenoid valve sealing gasket 65 is flicked keeps certain distance between the upper-end surface of electromagnetic valve body 61, then the upper end of through hole 610 is not sealed by solenoid valve sealing gasket 65, solenoid valve 61 all communicates with clutch release slave cylinder 10, oil storage cylinder 20, all regions oil pressure is equal, and oil can free-flow, and now solenoid valve is channel status.
When coil 62 is energized, through hole 610 seals by the upper-end surface that solenoid valve sealing gasket 65 is drawn onto electromagnetic valve body 61, and the oil circuit through solenoid valve disconnects.If now in clutch release slave cylinder 10, pressure is greater than pressure in oil storage cylinder 20, the sealing gasket 42 of one-way valve is compacted seals oil inlet hole 440, then liquid oil can not pass in and out, and in clutch release slave cylinder 10, oil pressure is larger, and sealing gasket 42 impacting force is larger, and it is better to seal; If the oil pressure of oil storage cylinder 20 is greater than clutch release slave cylinder 10 oil pressure, then the liquid oil in oil storage cylinder 20 overcomes the spring 43 elastic force acting of upper one-way valve 40, and push sealing gasket 42 open and enter in clutch release slave cylinder 10, upper one-way valve 40 is path.
Lower solenoid valve 70 working principle is with solenoid 60, and because bottom has piston rod 90 to pass through, therefore structure is adjusted accordingly, as shown in Figure 1.
Piston rod 90 is through the corresponding solenoid valve sealing gasket 65 of lower solenoid valve 70, and stretch out outside lower solenoid valve 70, its end and end cap 200 are fastenedly connected, and piston rod 90 is moved up and down end cap 200 can be driven simultaneously to move.Also have an outer cylinder sheath 30 at oil storage cylinder 20 skin, oil storage cylinder 20 and all concyclic heart of clutch release slave cylinder 10 are positioned within outer cylinder sheath 30 coaxially.Namely the edge of end cap 200 is connected with outer cylinder sheath 30 bottom buckle, piston rod 90 is moved up and down and is converted into moving up and down of outer cylinder sheath 30.
The top of outer cylinder sheath 30 is end connections of shock-absorbing spring 100.Pneumatic spring selected by the shock-absorbing spring 100 of this preferred embodiment.By known above, the adapter ring 21 forming air chamber is equipped with on the top of oil storage cylinder 20.Below adapter ring 21, T-Ring 22 outer with connects, and outer T-Ring 22 connects with the top of shock-absorbing spring 100, then shock-absorbing spring 100, outer cylinder sheath 30, outer T-Ring 22, end cap 200 surround an enclosed cavity jointly with air reservoir 20, only have air in described cavity.When piston rod 90 drives outer cylinder sheath 30 to move up and down with wheel, the inner cavity volume of shock-absorbing spring 100 also can change thereupon, produces elastic strain, cooperating cylinder 20 is reached effectiveness in vibration suppression together.
In the present embodiment, the spring that shock-absorbing spring 100 adopts rigidity lower, to improve damping property, strengthens travelling comfort.Shock-absorbing spring 100 of the present invention also can adopt novel shock-absorbing spring 100 also can adopt other various motor spring, as helical spring, leaf spring, torsion bar spring, hydro-pneumatic spring etc.In order to give full play to the superiority of controllable extensible vibration damper, the present invention adopts pneumatic spring and coordinates gas-filled pump, accessory air-space and solenoid electric valve to improve the overall performance of automotive suspension further, as the inflation pressure by changing pneumatic spring, vehicle body height can be changed easily, can also by the accessory air-space of solenoid valve shuts pneumatic spring, change the swept volume of pneumatic spring, thus change the rigidity of pneumatic spring, with the needs of the different operating mode of applicable automobile.
Oil of the present invention, the damping oil that preferred viscosities is less, makes fluid less by the damping of solenoid valve, improves sensitivity and travelling comfort.
The advantage of direct action solenoid valve is that structure is simple, is swift in response, and easily processes, its cost is low, reliable performance, relative to guide electromagnetic valve, direct driving type electromagnetic valve arrangement is simple, cost is low, one-way valve and solenoid valve integrate, and jointly on electromagnetic valve body, offer oil circuit, the upper and lower oil circuit being respectively solenoid valve and one-way valve, thus simplify overall structure, reduce manufacture requirements and manufacture cost.
Solenoid valve usually and automobile real-time state monitoring system with the use of, upper and lower solenoid valve 60,70 is connected with acceleration transducer, has acceleration upwards, then by certain electric controller, lower solenoid valve 70 is energized when acceleration transducer measures vehicle body; Otherwise when measuring downward acceleration, then solenoid 60 is energized.By so changing the working state of solenoid valve to control the flow direction of clutch release slave cylinder internal damping oil, thus controlling the retracted position of vibration damper, reaching the object of vibration damping.
In a particular application:
1. when evenness of road surface, rise and fall without height time, solenoid valve to be in Shang normal working ， solenoid valve 60 ╱ 70 under ╱ and to be path, and Shang clutch release slave cylinder 10, ╱ lower chamber internal damping oil can free-flow, and the effect that piston 80 does not stress is free state.The weight of vehicle body is born by shock-absorbing spring 100.
2. when bump, wheel upwards accelerated motion time, piston 80 moves upward, solenoid 60 power-off, and lower solenoid valve 70 is energized; Then clutch release slave cylinder 10 upper end oil circuit is path, and fluid can flow out by via through holes 610; Lower solenoid valve 60 is closed, and lower one-way valve 50 one-way passage, fluid is covered rapidly by lower one-way valve 50, then piston 80 can move upward with very little damping.That is, the rigidity of whole vibration damper is little, and wheel can move upward with piston 80 reaction rapidly, and vehicle body is only subject to spring force upwards and very little damping force, thus can substantially remain stable, thus alleviates the vibration that bump brings.
3., when road surface depression, wheel accelerate to move downward, piston 80 moves downward, and solenoid 60 is energized, the power-off of lower solenoid valve 70; Lower solenoid valve 70 is path, and fluid can flow out through the through hole 610 of lower solenoid valve 70; Clutch release slave cylinder 10 upper end oil circuit is open circuit, and upper one-way valve 40 one-way passage, fluid covers rapidly in clutch release slave cylinder 10 upper cavity.Equally, damping force suffered when piston 80 moves downward is very little, and wheel receives spring force and very little damping force, can decline rapidly to support vehicle body, thus slows down the body vibrations that road surface depression brings.
4., when vehicle needs to turn to, during the control actions such as acceleration or braking, wheel is without acceleration, vehicle body is subject to inertial force effect, and now upper and lower solenoid valve 60,70 is all energized, and clutch release slave cylinder 10 upper and lower cavity is open circuit, one-way valve one-way passage, fluid all can only flow into, and can not flow out.Now piston 80 can not move, damper stiffness is large, can not compress or stretch, thus make vehicle body racing, anxious the situation such as to stop under vibration damper pull vehicle body and wheel to be consistent, avoid the handling decline, overturn of vehicle body etc. that cause because damper stiffness is low, thus improve bend passing capacity, acceleration and deceleration time vehicle stability.Meanwhile, vibration damper can complete rapidly little by rigidity, that good springiness is large to rigidity, lower wall is steady transformation, highly sensitive, reliable performance.
Therefore, electronic control shock absorber of the present invention is a kind of vibration damper of controllable extensible, there are 2 Unidirectional solenoid valves and 2 to supplement the auxiliary one-way valve of fluid to clutch release slave cylinder, by connecting and cut off the electric current leading to 2 Unidirectional solenoid valves, 4 kinds of extreme working staties can be obtained: 1, free-extension; 2, only stretch and do not contract; 3, only contracting is not stretched; 4, non-telescoping.
When needing piston to stretch, leaving, it moves freely, and it is then closed in the other direction and makes it can only single-way moving; When needing piston motionless, clutch release slave cylinder about 10 blocks and piston is unable to stir any more.And the damping shock absorber that existing throttle diameter regulates is with the damping shock absorber of electricity ╱ magneto-rheological vibration damping liquid, although the movement of piston can be slowed down by damping adjusting, but can not the movement of control piston completely, that is, when piston moves up and down, can move it by damping adjusting, but there is the possibility of piston to movement in the other direction; And when making piston keep motionless by increase damping, still likely have fluid to force piston to be shifted up and down by damping hole.Visible, electronic control shock absorber of the present invention fundamentally solves the contradiction of riding comfort and operational stability, is better than existingly being regulated the vibration damper realized by damping completely.
Controllable extensible vibration damper of the present invention is simple and reliable, and cost is low, and it coordinates the control of logical circuit; thus reach change resistance of shock absorber; or make the effect of vibration damper unidirectional movement, thus solve travelling comfort and handling contradiction. wherein piston rod, oil storage cylinder; clutch release slave cylinder; guide sleeve, the parts such as oil sealing are equal to general vibration damper, are convenient to large-scale production; reducing costs. its global shape is also suitable with original vibration damper size shape, conveniently detachable.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; do not departing under the ambit that present inventive concept and claim protect, also can make a lot of form, these all belong within protection of the present invention.
