Decaying vibration, improves vehicle driving ride comfort and control stability.By providing flowing and valve arrangement between cylinder chamber
Be designed or implemented mode, damper is arranged to have specific damping behavior.In the structure of damper, the chamber of piston is divided into
Lower two chambers.
When automotive wheel rolls on protrusion or rolls out pit, wheel shifts near vehicle frame (vehicle body), and damper is compressed, for compression
Stroke；Damper linking member moves down；Piston rod leads resetting valve system to move downward, and the cavity volume below connecting rod reduces, oil pressure liter
Height, epicoele carries out oil liquid supplement in the flow side piston upper that a part of oil liquid is flowed by resetting valve system flowing valve.Due to upper
Chamber accounts for a part by connecting rod, and upper intracavitary increased volume is less than the volume that cavity of resorption reduces, therefore some oil liquid pushes pressure open
Contracting valve system, the compressed side oil storage cylinder for flowing into compressing valve system generate compression damping power.These valves realize to suspension the throttling of oil liquid
The damping force of compression movement.When automotive wheel is rolled off protrusion or rolls into pit, wheel is removed with respect to vehicle body, damper tension
It stretches, is extension stroke；Damper piston moves up at this time；Stroke is restored, piston rod leads resetting valve system to move upwards, vibration damping
Device inner piston epicoele oil pressure increases, and flowing valve is closed；In the recovery side inflow that upper intracavitary a part of oil liquid passes through resetting valve system
Cavity of resorption generates recovery damping force.Similarly, since the presence of connecting rod, the oil liquid come from epicoele stream is not enough to increased full of cavity of resorption institute
Volume, under it is intracavitary generate certain vacuum degree, at this moment a part of oil liquid in oil storage cylinder is flowed by the compensation side of compressing valve system
Interior cavity of resorption supplements oil liquid.At this point, the throttling action of these valves realizes the damping force to suspension stretching exercise.
But damping force can not achieve and voluntarily adjust in existing damper, damping force value is constant nonadjustable, but
Be due to vehicle in the process of moving, can be there are many road conditions be travelled, therefore single damping force value is no longer satisfied consumer
Needs, need exist to research and develop a kind of adaptive transmission control, the handling of Lai Tigao automobile, stability and comfort.
