Abstract
The invention discloses a shock absorber for a suspension system, which comprises a piston rod, a piston, a working cylinder and an oil storage cylinder, wherein the lower end of the piston rod is provided with the piston and extends into the working cylinder, the working cylinder is arranged in the oil storage cylinder, the upper part of the working cylinder is provided with an oil seal, the upper end of the piston is provided with a rebound valve, the lower end of the piston is provided with a circulating valve, and the bottom surface of the working cylinder is provided with a compression valve and a compensation valve. The invention has the characteristics of simple structure, easiness in realization, good vibration attenuation effect and no leakage of oil, and can be widely applied to various vehicles.
Description
Technical field
The present invention relates to automobile component, be specifically related to a kind of suspension system vibration damper.
Background technique
Produce vibration because elastic element is hit in the suspension system,, be in parallel installed with vibration damper with elastic element in the suspension for improving vehicle running smoothness; With attenuation vibration; Vibration damper and elastic element are being born and are being cushioned the task of hitting with vibration damping, and damping force is excessive, and suspension elasticity will be degenerated; Even the vibration damper link is damaged, thereby to regulate elastic element and this contradiction of vibration damper.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, a kind of suspension system vibration damper is provided.
The present invention for realizing the technological scheme that above-mentioned purpose adopted is: a kind of suspension system vibration damper, comprise piston rod, piston, clutch release slave cylinder, oil storage cylinder, and said piston-rod lower end is equipped with piston; And put in clutch release slave cylinder; Said clutch release slave cylinder is installed in the said oil storage cylinder, and said clutch release slave cylinder top is equipped with oil sealing, and said piston upper end is equipped with rebound valve; The lower end is equipped with flowing valve, and said clutch release slave cylinder bottom surface is equipped with compression valve and recuperation valve.
Said oil storage cylinder top is equipped with dust-proof cover, and said piston rod upper end is fixedly connected with dust-proof cover.
Said piston rod is connected through gland nut with piston.
Characteristics of the present invention are: simple in structure, be easy to realize, and good damping result, fluid is non-leakage, can be widely used on the various vehicles.
Description of drawings
Fig. 1 is a schematic representation of the present invention.
Wherein: 1, piston rod 2, clutch release slave cylinder 3, piston 4, rebound valve 5, oil storage cylinder 6, compression valve 7, recuperation valve 8, flowing valve 9, dust-proof cover 10, oil sealing.
Embodiment
As shown in Figure 1, the present invention includes piston rod 1, piston 3, clutch release slave cylinder 2, oil storage cylinder 5, said piston rod 1 lower end is connected with piston 3 through gland nut; And put in clutch release slave cylinder 2; Said oil storage cylinder 5 tops are equipped with dust-proof cover 9, and said piston rod 1 upper end is fixedly connected with dust-proof cover 9, and said clutch release slave cylinder 2 is installed in the said oil storage cylinder 5; Said clutch release slave cylinder 2 tops are equipped with oil sealing 10; Said piston 3 upper ends are equipped with rebound valve 4, and the lower end is equipped with flowing valve 8, and said clutch release slave cylinder 2 bottom surfaces are equipped with compression valve 6 and recuperation valve 7.
When compression stroke, automotive wheel moves nearly vehicle body, and vibration damper by compression; Vibration damper inner carrier 3 moves down at this moment, the volume reducing of piston lower chambers, and oil pressure raises; The fluid flowing valve 8 of flowing through flows to (epicoele) above the piston 3, and epicoele is by piston rod 1 a part of space that accounted for, thereby the volume that reduces less than cavity of resorption of the volume that increases of epicoele; So part fluid is just pushed compression valve 6 open, flows back to oil storage cylinder 5, these valves form the damping force that suspension moves by compression to the saving of oil; When extension stroke, wheel is equivalent to away from vehicle body, and vibration damper is stretched, and at this moment the piston 3 of vibration damper moves up.The piston upper chamber oil pressure raises, and flowing valve 8 is closed, and the fluid in the epicoele is pushed rebound valve 4 open and flowed into cavity of resorption; Because the existence of piston rod; The fluid that comes from epicoele stream is not enough to be full of the volume that cavity of resorption increases, and instigator's cavity of resorption produces a degree of vacuum, and at this moment the fluid in the oil storage cylinder 5 is pushed recuperation valve 7 open and flow to cavity of resorption and replenish; Because the throttling action of these valves plays damping function when being suspended in stretching exercise; The design of the rigidity of rebound valve 4 springs and pretightening force greater than compression valve 6, under same pressure effect, the long-pending summation of the passage section in rebound valve 4 and corresponding normal open slit is less than compression valve 6 and corresponding normal open slit channel cross-sectional area summation; This makes damping force that the extension stroke of vibration damper produces greater than the damping force of compression stroke, reaches the requirement of rapid vibration damping.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
