Abstract
The utility model relates to an integrated dust shield for an automobile damper. The integrated dust shield comprises a dust shield and a buffer spring, which are vulcanized into one body, and a buffer spring underlay is integrally arranged at one end of the buffer spring in the dust shield. The lower surface of the buffer spring underlay is connected to the upper end oil sealing of the damper, and the upper surface of the buffer spring underlay is connected to the buffer spring. Both ends of the dust shield have a closed end structure.
Description
Technical field
The utility model belongs to vibration damper field, refers to a kind of vapour vehicular shock absorber, refers to especially a kind of integrated dust-proof cover of automobile absorber.
Background technique
In vehicle traveling process, particularly suspension system is subject to the impacts such as road surface and produces vibration, in order to overcome the vibrations in running process, improves comfort property, in existing automobile, is widely used vibration damper in suspension system.The vibration damper of existing automotive field is with hydraulic damper, its working principle is when between vehicle body and vehicle bridge during vibrated generation relative movement, piston in vibration damper is by moving up and down, damping oil in vibration damper chamber is flowing in another chamber from chamber through hole repeatedly just, now, by the friction between hole wall and fluid and the intermolecular friction of fluid, vibration is formed to damping force, thereby realize damping object.
In existing suspension system, the effect of vibration damper is very important, and for dustproof also show very necessary of vibration damper, general vibration damper all will be installed dust-proof cover.Damper dust-proof cover in existing technology is Open architecture, there is certain gap with vibration damper urceolus, and having dust or the silt lower openings by dust-proof cover, such structure is deposited on the oil sealing and piston rod of vibration damper, cause the scuffing of piston rod and oil sealing to cause leakage of oil, thereby reduce working life.On the other hand, such structure can cause vibration damper to have jam phenomenon, affects the normal work of vibration damper.
In addition, in order to realize the buffering to the power of vibration damper, the upper cover of piston rod outside the housing of vibration damper is equipped with damping spring, so just need to be at the upper cover of piston rod shock mount pad of vibration damper, and the existing spring pad using is independent structure, manufactures and installation procedure complexity.And damping spring is in the course of the work, can produce and clash into piston rod etc., cause noise to increase.
Model utility content
In order to overcome existing damper dust-proof cover, can not realize the jam phenomenon of better dustproof problem, vibration damper and improve the dust-proof cover of vibration damper and the installation procedure problem of damping spring, and reduce the operational noise of damping spring, a kind of integrated dust-proof cover of automobile absorber is provided.
The utility model is achieved through the following technical solutions:
An integrated dust-proof cover for automobile absorber, includes dust-proof cover and damping spring; Described dust-proof cover and damping spring sulfuration are structure as a whole; In dust-proof cover, one end of damping spring has been wholely set damping spring underlay, and the upper end oil sealing of the lower surface of described damping spring underlay and vibration damper joins, and upper surface and the damping spring of damping spring underlay join; The two ends of described dust-proof cover are provided with closing-in structure.
Described dust-proof cover is with some folds.
When damping spring compresses, damping spring is positioned at the outmost turns of dust-proof cover fold.
The lower surface of described damping spring underlay is plane, and upper surface is for to match with one end of damping spring.
The internal diameter of described damping spring underlay is less than the minimum diameter after dust-proof cover compresses.
Damping spring underlay and dust-proof cover are installed on has a fold at least between vibration damper urceolus.
The utility model with the beneficial effect of prior art is:
1, because one in dust-proof cover is synthetic, there is damping spring, can prevent that dust-proof cover from coming off and can reduce the noise of damping spring when work.
2, effectively reduced manufacturing procedure.
Accompanying drawing explanation
Fig. 1 is the utility model dust-proof cover schematic cross-section.
Embodiment
By specific embodiment, describe the technical solution of the utility model in detail below, should be understood that following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as be the restriction to technical solutions of the utility model.
In this supporting paper, on described vibration damper urceolus, draw-in groove is that on piston rod, draw-in groove is the part being connected with vehicle frame with the one end through piston rod.
As shown in Figure 1, a kind of integrated dust-proof cover of automobile absorber, includes dust-proof cover 1 and damping spring 4; Dust-proof cover 1 is structure as a whole with damping spring 4 sulfurations.In the present embodiment, what dust-proof cover adopted is rubber, also can adopt other macromolecular material in other embodiments.
Piston rod is through dust-proof cover, and dust-proof cover is with some folds, and the fold of the axial cross section of dust-proof cover is similar to the connection of a plurality of W, and dust-proof cover is arranged on vibration damper urceolus on draw-in groove and piston rod between draw-in groove; One end of the interior damping spring 4 of dust-proof cover 1 has been wholely set damping spring underlay 2, and the other end is provided with on damping spring and pads 3; The lower surface of damping spring underlay is plane, and upper surface is for to match with one end of damping spring.The upper end oil sealing of the lower surface of damping spring underlay and vibration damper joins, and upper surface and the damping spring of damping spring underlay join; The two ends of described dust-proof cover are provided with closing-in structure.
The internal diameter of damping spring underlay is less than the minimum diameter after dust-proof cover compresses.
In the present embodiment, damping spring underlay and dust-proof cover are installed on and between vibration damper urceolus, have a fold at least.
In the present embodiment, the maximum outside diameter partial vulcanization when compressing is in one with the fold of dust-proof cover for damping spring, and in integrated dust-proof cover compression process, the dust-proof cover fold between adjacent two spring bodies is positioned at the inner ring of dust-proof cover like this.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present invention is by claims and be equal to and limit.
