Abstract
The utility model relates to an automobile vibration damper with a dust cover. The automobile vibration damper comprises an outer cylinder and an inner cylinder, a piston valve assembly, a bottom valve assembly and a piston rod are arranged in the inner cylinder, the piston valve assembly is arranged on the piston rod, the bottom valve assembly is arranged at the bottom of the inner cylinder, and a guide apparatus and an oil seal are arranged at the upper end of the inner cylinder. The automobile vibration damper is characterized in that the dust cover is sleeved outside the upper end of the outer cylinder, the dust cover comprises a cover body and a dust cap, the cover body is arranged in a split mode, the dust cap is arranged at the upper end of the cover body, and a through hole which is used for the piston rod to penetrate through is arranged on the dust cap. By means of the technical scheme, the automobile vibration damper with the dust cover is capable of effectively preventing dust and impurities from entering into the outer cylinder and the inner cylinder, so that the reliability of a vibration dumping performance of the vibration damper is guaranteed.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of automobile absorber with dust-proof cover.
Background technique
At present, existing automobile absorber has generally comprised outer shell, inner casing, is provided with piston valve assembly, bottom valve assembly, piston rod in the inner casing, and the piston valve assembly is arranged on the piston rod, and bottom valve assembly is arranged on the inner casing bottom, and the inner casing upper end also is provided with guider, oil sealing.
But the automobile absorber of this structure often has some dusts, impurity and gets in outer shell, the inner casing from the upper end of outer shell, influence piston valve assembly, the bottom valve assembly of oil sealing and inside, and then makes that the damping effect of vibration damper is poor.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of automobile absorber with dust-proof cover, can prevent effectively that dust, impurity from getting into outer shell, inner casing, thereby the damping performance that can guarantee vibration damper is reliable.
The technological scheme of the utility model: a kind of automobile absorber with dust-proof cover; Include outer shell, inner casing; Be provided with piston valve assembly, bottom valve assembly, piston rod in the inner casing, the piston valve assembly is arranged on the piston rod, and bottom valve assembly is arranged on the inner casing bottom; The inner casing upper end also is provided with guider, oil sealing; It is characterized in that: the outside that is positioned at the outer shell upper end also is arranged with dust-proof cover, and the dust cover that described dust-proof cover includes the cover body of split setting and is arranged on the cover body upper end, described dust cover are provided with the through hole that supplies piston rod to pass.
Adopt technique scheme, can prevent effectively that through the dust-proof cover that is provided with dust, impurity from getting into outer shell, inner casing, thereby the damping performance that can guarantee vibration damper is reliable; The dust-proof cover split is provided with, and can conveniently process, install.
The further setting of the utility model: described dust cover upper end also is provided with buffer stopper, and described buffer stopper is set on the piston rod, and described buffer stopper upper end also is provided with and is used to limit the locking nut of buffer stopper to piston rod upper end slippage.
Adopt above-mentioned further setting, the buffer stopper of setting can reduce vibration damper when thump, and vibration damper is protected in the impact that receives effectively.
Further being provided with again of the utility model: also be provided with guide pin bushing between described buffer stopper and the piston rod.
Adopt above-mentionedly further to be provided with again, the guide pin bushing of setting, can so that buffer stopper along piston rod to good buffer effect.
