Description
Technical field
The present invention relates to vibration damper field, particularly relate to a kind of adjustable shock absorber.
Background technique
Since automobile become modern live requisite instrument just and our life more and more tightr; Along with people are to the raising of quality of life, the requirement of people to the handling of automobile and travelling comfort is more and more higher, and people devise out a lot of shock absorbing apparatus for this reason.But because different driving conditions is different to the requirement of vibration damper damping function ability, common hydraulic damper can not make in good time adjustment according to the size of different track and different loads, it is poor to the effect of vehicle body shock attenuation, affects the handling of vehicle and travelling comfort.For this reason, people need a kind ofly can meet the vibration damper that vehicle can produce good damping function under different tracks and loaded-up condition.
In order to the damping adjustability problem of vibration damper, engineer constantly explores and innovates, and proposes the scheme of solution miscellaneous.Such as, a kind of damper regulation mechanism patent announcement number of adjustable vibration damper is: CN101070890B to have human hair to understand, this controlling mechanism, adopt and the sealing valve block that a piece is fixed on joint between cylinder barrel is set, sealing valve block opens hole, in through hole, plugs front fine and rear thick taper valve core, shock mount is added between valve block and spool, when changing the position relationship between spool and valve block, its flow area also changes thereupon, thus produces damping change.This project organization is simple, easy to adjust, but the change of damping completes by the mating reaction between vital part, so require higher to the required precision and coupling sealing valve block, spool and spring.In addition, in this mechanism, the positioning and locking of spool is the power by pressurized gas effect and spool face, and when running into high speed and high pressure liquid stream, controlling mechanism will become unstable.So this scheme needs further improvement just can be applied on existing vibration damper product.
The present invention mainly solves that the adjustable technical stability of existing damping is poor, and technological requirement is high, and working life is short, the defect that cost of production is high.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of adjustable shock absorber, better can solve the adjustable technical stability of existing damping poor, technological requirement is high, and working life is short, the defect that cost of production is high.
Technological scheme of the present invention realizes like this.
A kind of adjustable shock absorber, comprise valve seat, fuel tank, diversion pot, clutch release slave cylinder, piston rod, director assembly, valve base sealing is connected to below fuel tank, diversion pot is arranged on fuel tank inside, clutch release slave cylinder is arranged on diversion pot inside, and piston rod is arranged on clutch release slave cylinder inside, and piston rod is connected with outside load-bearing material through the top of fuel tank, connect piston assembly bottom piston rod, piston assembly is provided with both direction contrary one-way valve c and one-way valve d; Director assembly is arranged on the top of fuel tank, diversion pot, clutch release slave cylinder, for location and assembling diversion pot, clutch release slave cylinder, piston rod etc., director assembly is provided with normal open hole, normal open hole UNICOM work epicoele and the Oil Guide chamber between diversion pot and clutch release slave cylinder, also comprise and be divided into resistance sheet and the two-part support both compression valve assembly of lower ring, the upper resistance sheet of described support both compression valve assembly is arranged in clutch release slave cylinder, and upper resistance sheet is provided with both direction contrary one-way valve a and one-way valve b; The lower ring of described support both compression valve assembly is provided with two through holes, and a through hole UNICOM Oil Guide chamber and oil guiding hole another through hole UNICOM hinder sheet underlying space and the oil storage chamber between fuel tank and diversion pot; Valve seat has the blind hole one of UNICOM's oil guiding hole and spill port, cylindrical regulating spool is also provided with in blind hole one, described regulating spool one end is provided with axial blind hole two, the inwall of blind hole two is provided with the radial direction through hole of multiple different pore size communicated with regulating spool outer wall, and the position of these radial direction through hole is corresponding with spill port.
As further technological scheme of the present invention, described regulating spool outer end is also provided with hand knob or electronic knob.
As further technological scheme of the present invention, described radial direction through hole is distributed in same radial cross section, is equidistant, is arranged in order by pore size between each radial direction through hole.
As further technological scheme of the present invention, circulation positioning device is equipped with in described valve seat and regulating spool junction.
As further technological scheme of the present invention, described regulating spool outer wall is provided with seal ring.
When vibrations occur in the external world, piston rod is forced to move up and down, and passes in and out the vibration damper clutch release slave cylinder of sealing simultaneously.When piston rod is up, the pressure increase of work epicoele, fluid enters Oil Guide cylinder by normal open hole, flow into valve seat through oil guiding hole again, form small oil cavity at blind hole two position of regulating spool, after the pressure of small oil cavity arrives certain value, fluid, through radial direction through hole and spill port, finally arrives oil storage chamber.In this process, when a rotary manual knob, the size of the radial direction through hole corresponding with it with spill port changes, and it provides, and damping force is also corresponding to change, and the damping realizing the up process of piston rod is adjustable.If worked in the process, upper cavity pressure is too high, and when acquiring a certain degree, the one-way valve c on piston assembly opens, pressure drop, and this process both ensure that the relatively stable of damping, and the overload that simultaneously it also avoid vibration damper is damaged.
When piston rod is descending, work cavity of resorption pressure increase, certain pressure reduction is formed with work epicoele, now fluid is full of epicoele through the one-way valve d of piston assembly, pass through spill port, because piston rod enters the clutch release slave cylinder of sealing in descending process, internal volume is caused to reduce, the inner a part of fluid of clutch release slave cylinder, through the normal open hole of director assembly, Oil Guide cylinder, oil guiding hole arrives the radial direction through hole of regulating spool, the size of radial direction through hole is selected by rotating regulation valve core, the size of the radial direction through hole corresponding with it with spill port changes, then it provides that damping force is also corresponding to change, the damping realizing the up process of piston rod is adjustable.If work cavity of resorption overpressure in the process, when acquiring a certain degree with oil storage chamber pressure difference, the one-way valve b on support both compression valve assembly opens, pressure drop, this process is ensure that damping metastable while, and the overload that it also avoid vibration damper is damaged.
Another when external hand knob cancellation, when controlling by electric knob device, automatically controlled adjustment can be realized, and Car Electronic Control system can be included in.When driver and passenger's Subjective need regulates, provide instruction by electronics system, electric knob device receives and performs instruction, and rotating regulation valve core is adjusted to corresponding position, realizes damping and regulates.
The invention provides a kind of bidirectional damper adjustable damper, and stable, durable; Simplify manufacture and assembly technology, improve efficiency; Achieve the large-scale production of two-way adjustable damper.
