Abstract
The utility model relates to an anti-dust device of an automobile shock absorber. The anti-dust device comprises an anti-dust cover, a shock absorber outer-cylinder upper channel section and a piston-rod upper channel section. A piston rod passes through the anti-dust cover which is arranged between the shock absorber outer-cylinder upper channel section and the piston-rod upper channel section. A buffer spring underlay is integrally arranged on the joint part where the inside of the anti-dust cover and the shock absorber outer-cylinder upper channel section are connected. The lower surface of the buffer spring underlay is connected with an upper oil seal of the shock absorber. The upper surface of the buffer spring underlay is connected with a buffer spring. Two ends of the anti-dust cover are provided with necking-in structures.
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 dust guard 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.
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, a kind of dust guard of automobile absorber is provided.
The utility model is achieved through the following technical solutions:
A dust guard for automobile absorber, includes on dust-proof cover, vibration damper urceolus draw-in groove on draw-in groove and piston rod; Piston rod is through dust-proof cover, and dust-proof cover is arranged on vibration damper urceolus on draw-in groove and piston rod between draw-in groove; The top at the interior position that is connected with draw-in groove on vibration damper urceolus of described dust-proof cover 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.
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 is arranged at dust-proof cover position and dust-proof cover and is installed on and on vibration damper urceolus, between draw-in groove, has a fold at least.
The utility model with the beneficial effect of prior art is:
1,, by the technical program, the two ends of dust-proof cover combine and realize sealing with draw-in groove on draw-in groove and piston rod on vibration damper urceolus, have effectively stopped entering of dust and silt.
2, because one in dust-proof cover is synthetic, have damping spring underlay, directly by damping spring with dust-proof cover combination, prevent that dust-proof cover from coming off.
3, effectively reduced manufacturing procedure.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model dust cover structure schematic diagram;
Fig. 3 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 to Figure 3, a kind of dust guard of automobile absorber, includes on dust-proof cover 1, vibration damper urceolus draw-in groove 5 on draw-in groove 4 and piston rod.
The part of the outstanding vibration damper housings 2 of piston rod 3 is through dust-proof cover 1, and dust-proof cover 1 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 1 is arranged on vibration damper urceolus on draw-in groove 4 and piston rod between draw-in groove 5; The top at the interior position that is connected with draw-in groove on vibration damper urceolus of described dust-proof cover has been wholely set damping spring underlay 7, and the lower surface of described 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 is arranged at dust-proof cover position and dust-proof cover and is installed on and on vibration damper urceolus, between draw-in groove, has a fold at least.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that not departing from principle of the present utility model and spirit and can carry out multiple variation, modification, replacement and modification to these embodiments, scope of the present utility model is by claims and be equal to and limit.
