Abstract
The utility model discloses a leak-proof shock absorber which comprises an oil storage tank, a working cylinder, a piston, a piston rod, a guide bearing, an oil seal seat and a dust shield. An oil seal is arranged on the oil seal seat; the lower end of the piston rod is connected with the piston and extends into the working cylinder; the upper end of the piston rod penetrates through the guide bearing and the end cover of the working cylinder in sequence; a return spring and a damping ring are arranged on the piston rod; the upper end of the return spring is connected with the lower end of the guide bearing; and the lower end of the return spring is connected with the upper end of the damping ring. The leak-proof shock absorber has simple design, reduces the friction between the piston rod and the guide bearing as well as the end cover of the working cylinder, prolongs the service life of shock absorber, improves the sealing performance of the shock absorber, and prevents the leakage of damping oil.
Description
Technical field
The utility model relates to a kind of vibration damper, particularly relates to a kind of anti-leak vibration damper.
Background technique
Automobile in the process of moving, suspension system produces vibrations because elastic element is hit, and has good stationarity, the vibrations of mounting shock absorber decay automobile in suspension when guaranteeing automobile running.What automobile absorber was commonly used is hydraulic damper.Its working principle is when receiving vibrations when relative movement occurring between vehicle frame (or vehicle body) and vehicle bridge, and the piston in the vibration damper moves up and down, and the fluid in the damping is flowing in another chamber from a chamber repeatedly just.Friction formed damping force to vibrations in friction between hole wall and fluid and fluid were intermolecular; Making the thump Conversion of energy is fluid heat energy; So when design, must fully take into account the sealing of hydraulic damper, if vibration damper leaks; To cause damping performance to descend even completely lose, thereby influence the usefulness of whole suspension.
Summary of the invention
The purpose of the utility model is that a kind of anti-leak vibration damper is provided in order to address the above problem, and this vibration damper can weaken the friction between piston and the clutch release slave cylinder end cap, has advantages such as long service life, good seal performance.
The utility model is realized above-mentioned purpose through following technological scheme: the utility model comprises oil storage cylinder, clutch release slave cylinder, piston, piston rod, guide bearing, oil sealing base and dust-proof cover; Said oil sealing base is provided with oil sealing; The lower end of piston rod connects piston and stretches in the clutch release slave cylinder; The upper end of piston rod is passed guide bearing and clutch release slave cylinder end cap successively; On said piston rod, be provided with return spring and damping ring, the upper end of said return spring and guide bearing lower ends, the lower end of return spring links to each other with the upper end of damping ring.
As preferably, be filled with sponge block between said dust-proof cover and the guide bearing.
As preferably, said damping ring is the rubber damping ring.
The beneficial effect of the utility model is:
Through return spring and damping ring being set and filling sponge piece between dust-proof cover and guide bearing on the piston rod; The utility model can weaken the friction between piston rod and the clutch release slave cylinder end cap effectively; And can adsorb the oil that end cap leaks; Prolong the working life of vibration damper, improved the sealing of vibration damper, avoided damping oil to leak the environmental pollution that causes.
Description of drawings
Fig. 1 is the sectional view of the utility model;
Among the figure: 1-dust-proof cover, 2-sponge block, 3-oil sealing base, 4-oil sealing, 5-guide bearing, 6-return spring, 7-damping ring, 8-oil storage cylinder, 9-clutch release slave cylinder, 10-piston rod, 11-piston, 12-damping oil, 13-compression valve, 14-recuperation valve.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
As shown in Figure 1, the utility model comprises oil storage cylinder 8, clutch release slave cylinder 9, piston 11, piston rod 10, guide bearing 5, oil sealing base 3 and dust-proof cover 1, clutch release slave cylinder 9, oil storage cylinder 8, piston 11 and piston rod 10 coaxial settings.Clutch release slave cylinder 9 is positioned at oil storage cylinder 8 inside, fills damping oil 12 in oil storage cylinder 8 and the clutch release slave cylinder 9.Be provided with piston 11 and the piston rod that is connected piston 10 in the said clutch release slave cylinder; The upper end of said piston rod is passed the upper end of guide bearing 5, clutch release slave cylinder 9 successively; Guide bearing 5 and oil sealing base 3 are arranged on the upper end of oil storage cylinder 8 and clutch release slave cylinder 9; Oil sealing base 3 is provided with oil sealing 4, is provided with compression valve 13 and recuperation valve 14 in the lower end of clutch release slave cylinder.Impact that vehicle receives and vibrations, the transmission through cylinder body makes piston to-and-fro motion in clutch release slave cylinder, comes flowing of Control work cylinder internal damping oil to realize damping shock absorption by the damping hole that is arranged on the piston.Because piston to-and-fro motion in clutch release slave cylinder in the damping process; Piston rod constantly rubs to the end cap of clutch release slave cylinder and oil storage cylinder; Make clutch release slave cylinder and oil storage cylinder produce wearing and tearing, the sealing surface between piston rod and clutch release slave cylinder, the oil storage cylinder is damaged, clutch release slave cylinder and the damping oil that seals in the cylinder are leaked.Compared with prior art, present embodiment is with return spring 6 and damping ring 7 on piston rod 10, and the upper end of return spring 6 links to each other with guide bearing 5, and the lower end of return spring 6 links to each other with damping ring 7.Damping ring in the present embodiment adopts the rubber damping ring.When the piston rod to-and-fro motion is too frequent and violent; Owing on piston rod 10, be provided with return spring 6 and damping ring 7; The active force that vibration damper can be through the damping hole on the damping ring produces during to the damping function of liquid and telescopic spring can make the to-and-fro motion of piston rod slack-off or weaken; Thereby weaken the friction between piston rod and guide bearing, the clutch release slave cylinder end cap, improved the sealability of vibration damper and prolonged working life of vibration damper.Leak in environment for fear of damping oil, also between dust-proof cover 1 and guide bearing 5, be filled with sponge block 2, said sponge block can adsorb the damping oil of from clutch release slave cylinder and oil storage cylinder, revealing well, has avoided damping oil to leak pollution on the environment.
Claims (3)
1. anti-leak vibration damper; Comprise oil storage cylinder, clutch release slave cylinder, piston, piston rod, guide bearing, oil sealing base and dust-proof cover, said oil sealing base is provided with oil sealing, and the lower end of piston rod connects piston and stretches in the clutch release slave cylinder; The upper end of piston rod is passed guide bearing and clutch release slave cylinder end cap successively; It is characterized in that: at said upper cover of piston rod return spring and damping ring are arranged, the upper end of said return spring and guide bearing lower ends, the lower end of return spring links to each other with the upper end of damping ring.
