Abstract
The utility model relates to a shock absorber with a good dustproof effect. The shock absorber with the good dustproof effect comprises a working cylinder, wherein a connecting rod is arranged in the working cylinder and extends out of one end in the working cylinder; a port of the working cylinder, from which the connecting rod extends out of the working cylinder, is provided with a guider; one end of the connecting rod, which extends out of the working cylinder, is provided with a first dustproof cover, and the first dustproof cover is of a stepped annular construction element; a smaller stepped end of the first dustproof cover is arranged on the connecting rod, and a larger end of the first dustproof cover as an installation port is arranged toward the working cylinder; the outer periphery of the working cylinder is provided with a second dustproof cover which is of an annular construction element; one end of the second dustproof cover is provided with a bending edge toward the annular center and the bending edge is clamped on the outer periphery surface of the working cylinder, and the other end of the second dustproof cover abuts against the stepped radial surface of the first dustproof cover in an extending manner so as to form seal fit. By adopting the scheme, the utility model provides the shock absorber which has long service life and has a good dustproof effect.
Description
Technical field
The utility model is specifically related to a kind of vibration damper of good dustproof effect.
Background technique
Concussion when vibration damper is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Existing vibration damper comprises clutch release slave cylinder, be provided with connecting rod in clutch release slave cylinder and stretch out from an end in clutch release slave cylinder, clutch release slave cylinder is positioned at the port that connecting rod stretches out clutch release slave cylinder and is provided with guider, traditional guider and connecting rod joint are mutually to external world in naked state, can the function of guider and a part of connecting rod be caused damage after long-time the use, reduced the working life of vibration damper.
Summary of the invention
The deficiency existed for prior art, the purpose of this utility model is to provide the vibration damper of a kind of long service life, good dustproof effect.
For achieving the above object, the utility model provides following technological scheme: comprise clutch release slave cylinder, be provided with connecting rod in clutch release slave cylinder and stretch out from an end in clutch release slave cylinder, clutch release slave cylinder is positioned at the port that connecting rod stretches out clutch release slave cylinder and is provided with guider, it is characterized in that: described connecting rod stretches out on an end of clutch release slave cylinder and is provided with the first dust cover, described the first dust cover is the stepped shape annular component, described the first dust cover stepped shape be sheathed on connecting rod than small end, larger end as mount inlet towards the clutch release slave cylinder setting, on described clutch release slave cylinder outer circumferential face, the second dust cover is set, described the second dust cover is annular construction member, the bending edges that described the second dust cover one end is provided with towards annular center is arranged in the clutch release slave cylinder outer circumferential face, the other end extends on the sagittal plane be butted on the first dust cover stepped shape and forms and be sealed and matched.
By adopting technique scheme; the setting of the first dust cover and the second dust cover adequately protect guider and connecting rod linkage section; the stepped shape setting of the first dust cover is more convenient for being installed on connecting rod; the bending edges of the second dust cover makes it more firm with coordinating of clutch release slave cylinder; be difficult for becoming flexible, the sagittal plane that the second dust cover is butted on the first dust cover stepped shape improves the dust-proof effect be sealed and matched greatly.
The utility model further is set to: the larger end of described the first dust cover extends to the port that clutch release slave cylinder stretches out connecting rod.
By adopting technique scheme, the first dust cover extends to quality and the dust-proof effect that port that clutch release slave cylinder stretches out connecting rod makes to block the first dust cover of guider and connecting rod linkage section and reaches optimization.
The utility model further is set to: the diameter of the larger end cross section of described the first dust cover and the second dust cover are 4:3 towards the ratio of the diameter of the first dust cover one end cross section.
By adopting technique scheme, the diameter of the larger end cross section of the first dust cover and the second dust cover can be for varied towards the ratio of the diameter of the first dust cover one end cross section, here preferred 4:3, from being sealed and matched and all angles dustproof reaches optimum balance.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
The cooperation schematic diagram that Fig. 2 is the first dust cover and the second dust cover in the utility model embodiment.
Embodiment
As shown in Fig. 1-Fig. 2, the utility model discloses a kind of vibration damper of good dustproof effect, comprise clutch release slave cylinder 1, be provided with connecting rod 2 in clutch release slave cylinder 1 and stretch out from the interior end of clutch release slave cylinder 1, clutch release slave cylinder 1 is positioned at the port that connecting rod 2 stretches out clutch release slave cylinder 1 and is provided with guider 3, connecting rod 3 stretches out on an end of clutch release slave cylinder 1 and is provided with the first dust cover 4, the first dust cover 4 is the stepped shape annular component, the first dust cover 4 stepped shapes be sheathed on connecting rod than small end 41, larger end 42 arranges towards clutch release slave cylinder 1 as mount inlet, the second dust cover 5 is set on clutch release slave cylinder 1 outer circumferential face, two dust covers are annular construction member, the bending edges 51 that the second dust cover 5 one ends are provided with towards annular center is arranged in the clutch release slave cylinder outer circumferential face, the other end extends on the sagittal plane 43 be butted on the first dust cover stepped shape and forms and be sealed and matched, the setting of the first dust cover 4 and the second dust cover 5 adequately protect guider 3 and connecting rod 2 linkage sections, the stepped shape setting of the first dust cover 4 is more convenient for being installed on connecting rod, the bending edges 51 of the second dust cover 5 makes it more firm with coordinating of clutch release slave cylinder 1, be difficult for loosening, the sagittal plane 43 that the second dust cover 5 is butted on the first dust cover 4 stepped shapes improves the dust-proof effect be sealed and matched greatly.
The larger end 42 of the first dust cover 4 extends to the port that clutch release slave cylinder 1 stretches out connecting rod 2, by adopting technique scheme, the first dust cover 4 extends to quality and the dust-proof effect that port that clutch release slave cylinder 1 stretches out connecting rod 2 makes to block the first dust cover 4 of guider 3 and connecting rod 2 linkage sections and reaches optimization.
The diameter of larger end 42 cross sections of the first dust cover 4 and the second dust cover 5 are 4:3 towards the ratio of the diameter of the first dust cover 4 one end cross sections, the diameter of larger end 42 cross sections of the first dust cover 4 and the second dust cover 5 can be for varied towards the ratio of the diameter of the first dust cover 4 one end cross sections, here preferred 4:3, from being sealed and matched and all angles dustproof reaches optimum balance.
