Description
Technical field
The present invention relates to a kind of shock absorber for vehicle.
Background technique
For improving the stationarity of automobile running; usual meeting mounting dampers in automotive suspension; the vibration damper that Vehicles Collected from Market adopts is hydraulic shock absorber mostly; its working principle is when relative movement appears in vehicle frame and vehicle bridge because of vibrations; piston up-down in vibration damper, the fluid in vibration damper chamber just flows into another chamber from a chamber repeatedly, now; the fluid Relative friction being positioned at active chamber forms damping force, thus reaches the effect of vibration damping.
Current double adjustable shock absorber has generally included clutch release slave cylinder, oil storage cylinder barrel, and be provided with piston, bottom valve in work cylinder barrel, described piston sleeve is established on the piston rod, and clutch release slave cylinder is divided into upper and lower two chambers by piston.When connecting rod drives piston to move downward, the chamber being positioned at lower end is compressed, and fluid flows into the chamber on top through piston, due to reason that oil pressure is too low time most of, required damping force can not be reached, so that vibration damper reaction is sensitive not, have impact on the effectiveness in vibration suppression of vibration damper.When described fluid flows into cavity of resorption through epicoele, easily there is foamed in vibration damper inner fluid, causes damping characteristic stable not, affect effectiveness in vibration suppression.
Summary of the invention
One is the object of the present invention is to provide to be quick on the draw, the vehicle shock absorber that damping force change is let out in slowly also effectively avoiding.
A kind of vehicle shock absorber, comprise connecting rod, clutch release slave cylinder, one is set in the urceolus on clutch release slave cylinder, and a gas wall be set on urceolus, active chamber is formed in clutch release slave cylinder, oil storage chamber is formed between clutch release slave cylinder and urceolus, bottom valve and piston valve are set in active chamber, described bottom valve is arranged on the bottom of active chamber, described piston valve is set in bottom connecting rod, the top of connecting rod arranges Sealing, described vehicle shock absorber also comprises the air bag that is sealedly connected on gas wall top, the top of connecting rod is covered by air bag, the bottom of connecting rod is located in clutch release slave cylinder, described piston valve comprises electromagnetic valve component from top to bottom successively, bounding means, compression valve assembly and the total member of piston valve, described bounding means comprises limiting stopper, spacing video disc and bolt, limiting stopper is fixed on bolt tail, spacing video disc to be enclosed within described bolt and to clip between limiting stopper and compression valve assembly, described spacing video disc has the end face of an indent, the bottom surface of a spherically shape, compression valve assembly comprises multiple compression valve block, the stacking setting of described compression valve sheet and from top to bottom diameter increase progressively step by step, compression valve block is located on bolt, being positioned at compression valve block is topmost connected on the bottom surface of spacing video disc, the annular oil streambuf that a Ge You center is gradually opened to peripheral dimension is formed between spacing video disc and described compression valve block.
The present invention adopts the beneficial effect of above technological scheme to be:
The bottom surface of the end face that spacing video disc has an indent and spherically shape, being positioned at compression valve block is topmost connected on the bottom surface of spacing video disc, the stacking setting of described compression valve sheet and from top to bottom diameter increase progressively step by step thus form the compression valve block group of a Pyramid, the annular oil streambuf that the Ge You center that formed between spacing video disc and described compression valve block is gradually opened to peripheral dimension.When connecting rod moves upward, fluid in clutch release slave cylinder spreads in the chamber between inflow electromagnetic valve component and compression valve block group downwards, and promote the compression of described compression valve block by described spacing video disc, first compression valve block is topmost positioned at by the center portion pushing and pressing of the protrusion of spacing video disc bottom surface spherical in shape, area of contact between this compression valve block and spacing video disc is less, therefore namely can form enough thrust at short notice and compress described compression valve block, namely the short time just can reach required damping force, vibration damper is quick on the draw, thus make automobile have good effectiveness in vibration suppression,
An annular oil streambuf gradually opened to connecting rod peripheral dimension by connecting rod center is formed between the spheric bottom surface of described spacing video disc and the compression valve block group in Pyramid, when connecting rod moves downward, fluid is by the downward diverging flow of chamber between electromagnetic valve component and compression valve block group, relax through the flow velocity of described oily streambuf to fluid, because oily streambuf is expanded to periphery gradually by connecting rod center, therefore connecting rod moves down in process and can continue to keep good resiliency, reduce the bubble level of clutch release slave cylinder fluid, chamber bottom the inflow clutch release slave cylinder that fluid can relax, and fluid not easily splashes, make the damping characteristic of vibration damper more stable, better effectiveness in vibration suppression can be obtained.
