Abstract

The utility model discloses a durable two-cylinder shock absorber. The durable two-cylinder shock absorber comprises a piston rod, a working cylinder and an oil storage cylinder, which are coaxially arranged, wherein a compression valve and a compensation valve are arranged on the lower part of the working cylinder; a piston, a rebound valve and a flow valve are arranged on the lower part of the piston rod; a guide seat and an oil seal are arranged on the top of the working cylinder; a dustproof cover is arranged on the top of the oil storage cylinder; a spring is arranged at the bottom of the working cylinder; the spring is cylindrical or conical; and the upper end of the spring is suspended or connected with the lower end of the piston rod. Under the condition of large external impact or shake, the downward movement distance of the piston rod is large, the spring can share part of the impact or shake of the piston rod, the working load of the shock absorber is reduced, and the service life of the shock absorber is prolonged.

Description

Durable dual-tube shock absorber
Technical field
The utility model relates to vibration damper, relates in particular to a kind of durable dual-tube shock absorber that is provided with spring at the clutch release slave cylinder tube bottom.
Background technique
Vibration damper is one of indispensable element of automobile, and dual-tube shock absorber is one of vibration damper commonly used.The working principle of dual-tube shock absorber is, from the impact and the vibrations on road surface, the transmission through cylinder body moves reciprocatingly piston with respect to clutch release slave cylinder in clutch release slave cylinder, come flowing of Control work cylinder internal damping oil to realize damping shock absorption by compression valve and recuperation valve.When the impact in the external world and vibrations were very big, the damping oil flow in the clutch release slave cylinder was bigger, and the working load of vibration damper is bigger, the easy corrupted of vibration damper.
Summary of the invention
In order to overcome the above problems, the utility model discloses durable dual-tube shock absorber.This durable dual-tube shock absorber through in the clutch release slave cylinder bottom spring being set, can be slowed down the impact and the vibrations of piston rod, prolongs the working life of vibration damper.
This durable dual-tube shock absorber; The piston rod, clutch release slave cylinder and the oil storage cylinder that comprise coaxial setting; The clutch release slave cylinder bottom is provided with compression valve and recuperation valve, and the bottom of piston rod is provided with piston, rebound valve and flowing valve, and the top of clutch release slave cylinder is provided with guide holder and oil sealing; The top of oil storage cylinder is provided with dust-proof cover, and the bottom of clutch release slave cylinder is provided with spring.
Spring is cylindrical or conical.
The top of spring is connected the bottom of piston rod or unsettled.
This durable dual-tube shock absorber, when foreign impacts or vibrations are big, can be through the lower end of spring conflict piston rod; Slow down and impact and vibrations, prolong the working life of vibration damper, avoid because of foreign impacts or vibrations too big; Make the acutely mobile or amount of flow of damping oil bigger, cause defective shock absorber.
Description of drawings
Fig. 1 is the structural representation of this durable vibration damper,
Fig. 2 is the structural representation that the durable vibration damper of basis of cone shaped spring is set,
Accompanying drawing is indicated tabulation: 1-dust-proof cover, 2-piston rod, 3-guide holder, 4-clutch release slave cylinder, 5-flowing valve, 6-recuperation valve, 7-compression valve, 8-oil storage cylinder, 9-rebound valve, 10,10 '-spring.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model.
This durable dual-tube shock absorber, clutch release slave cylinder 4, piston, guide holder 3 and oil storage cylinder 8 coaxial settings, the top of oil storage cylinder 8 is provided with dust-proof cover 1, and piston is provided with rebound valve 9 and flowing valve 5, and clutch release slave cylinder 4 bottoms are provided with compression valve 7 and recuperation valve 6.
As shown in Figure 1, between compression valve 7 and recuperation valve 6, be provided with helical spring 10, the spring upper end is unsettled; When the impact in the external world or vibrations were big, the distance that piston rod 2 moves down was bigger, and the damping of damping oil also can be bigger; Wearing and tearing to vibration damper are more serious, and when spring 10 during with 2 times end in contact of piston rod, spring 10 can bear the downward power of a part of piston rod 2; Bear impact or vibrations that part comes from the outside, alleviate the working load of vibration damper, prolong the working life of vibration damper.
Fig. 2 representes that a conical spring 10 ' is installed in the clutch release slave cylinder bottom, is installed between compression valve 7 and recuperation valve 6 and clutch release slave cylinder 4 inwalls around the lower end of cone shaped spring 10 '.When foreign impacts and vibrations were big, this cone shaped spring 10 ' can reach the damping effect identical with helical spring 10.
Spring 10 (the 10 ') upper end of clutch release slave cylinder bottom can be connected bottom piston rod, and the spring that is provided with like this has in the external world under the situation of impact or vibrations, just can share part and impact and shake, and prolongs the working life of vibration damper.
