The utility model has the advantages of simple structure, it is with low costs, dismantle and change convenience, with low costs.
Description
[technical field]
The utility model relates to mechanical field, particularly relates to the safety device that a kind of vibration damper is used.
[background technique]
In the suspension system of automobile, because being hit, elastic element produces vibration, for improving the automobile running stationarity, need in suspension, to be installed in parallel vibration damper with elastic element.Be attenuation vibration, adopt hydraulic shock absorber in the automobile suspension system mostly.For preventing that introduced contaminantses such as sand grains from entering vibration damper, dust-proof cover is installed on vibration damper generally.
The employing welding type metallic dust-proof cover that present vibration damper producer has, this mode good fixing effect, but cost is higher, the inwall of integrated type metal dust-proof cover is owing to the reason of technology is not generally carried out antirust processing simultaneously, inwall just is easy to produce iron rust and be shed to the shock absorber packing gland place like this, causes oil sealing scuffing and then leakage of oil and causes defective shock absorber.There is part vibration damper producer to adopt the dust-proof cover of non-metallic material in addition, the dust-proof cover external stability of polyethylene material is on the metal fixed base, this mode cost is low, but fixed effect is undesirable, contacts with the vibration damper urceolus easily, causes vibration damper urceolus coating to scrape and gets rusty, produce abnormal sound simultaneously, and this kind means of fixation is non-dismountable for disposably and permanently fixing, thereby can't be convenient for changing.A kind of dust-proof cover that is fixed on metal fixed base inner non-metallic material is disclosed in the prior art, but this kind mode install the back non-employing failure mode can't dismantle, thereby can't be convenient for changing.
So dust-proof cover that needs a kind of good fixing effect and be convenient for changing.
[summary of the invention]
The purpose of this utility model provides the dust-proof cover of a kind of good fixing effect, convenient disassembly.
The utility model is achieved in that
A kind of shock absorber dirt shield is provided, comprise metal fixed base and nonmetal dustproof cover body, the circumferencial direction of this nonmetal dustproof cover body one end is evenly distributed with at least three spring sheets, spring sheet is provided with projection, the circumferencial direction of this metal fixed base is evenly distributed with at least three perforates that match with projection, nonmetal dustproof cover body and metal fixed base assemble a time-out, and nonmetal dustproof cover body places in the metal fixed base, and being connected by projection and perforate.Rely on the elasticity of spring sheet that nonmetal dustproof cover body is installed in the metal fixed base easily, and can easily dismantle.
Projection is arranged on the middle part of spring sheet, and the width of spring sheet is greater than the width of projection, and the top of projection has certain distance apart from the top of spring sheet, and the both sides of projection and the both sides of spring sheet also have a segment distance.The area of spring sheet is greater than the area of projection, and the size of spring sheet is greater than the size of the perforate on the metal fixed base, thereby the perforate part is by the complete shutoff of spring sheet, the top that can partly not expose spring sheet side fluting and spring sheet from perforate, realize sealing effect, avoid introduced contaminants to enter nonmetal dustproof cover body inside from tapping.
Spring sheet on nonmetal dustproof cover body is to form like this: the top of described nonmetal dustproof cover body has opening, described opening is slotted downwards along its dual-side, promptly form described spring sheet on described nonmetal dustproof cover body, spring sheet one end connects nonmetal dustproof cover body.
Described metal fixed base is straight tubular, and the sidewall of described nonmetal dustproof cover body and described metal fixed base attachment portion is straight wall.During to pressurized, nonmetal dustproof cover body also can contact by maintenance face with the part that the metal fixed base matches, thereby can fix reliably, and makes dust-proof cover and vibration damper can keep good coaxality on nonmetal dust-proof cover side.
The end face that the standing part of metal fixed base links to each other with open part is the plane.On the top flanging is set at nonmetal dustproof cover body.And flanging is vertical with described dust-proof cover sidewall.The end face of metal fixed base is that face contacts with the flanging of nonmetal dustproof cover body, further guarantees reliability of fixation, makes dust-proof cover be difficult for departing from when receiving lateral force, can keep good coaxality.
For conveniently installing and making the gap between the urceolus of nonmetal dustproof cover body and vibration damper unlikely excessive, nonmetal dustproof cover body middle part has the inclination attachment portion, like this, nonmetal dustproof cover body is bigger than the diameter of nonmetal dustproof cover body afterbody with the diameter of metal fixed base attachment portion.
For strengthening connecting fixed effect, can also outside the sidewall of nonmetal dustproof cover body and metal fixed base non-contact part, stiffening rib be set.
Of the present utility model simple in structure, cost is low, and nonmetal dustproof cover body can be dismantled from the metal fixed base easily, only changes flimsy nonmetal dustproof cover body during replacing, and need not change the metal fixed base, can save cost.

[embodiment]
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the vehicle shock absorber dust-proof cover comprises metal fixed base 1 and nonmetal dustproof cover body 2, and metal fixed base 1 is fixed on the shock absorber piston rod 3, and nonmetal dustproof cover body 2 is fixed on metal fixed base 1 inside by cooperation.Being fixed on metal fixed base outside with nonmetal dustproof cover body compares; the part protection of easily wearing and tearing in nonmetal dustproof cover body 2 tops is in metal fixed base 1; metal fixed base abrasion resistance properties substantially exceeds the dust-proof cover of non-metallic material, thereby can improve the working life of whole dust-proof cover.
The circumferencial direction of these nonmetal dustproof cover body 2 one ends is evenly distributed with at least three spring sheets, in this embodiment, be distributed with four spring sheets 26, spring sheet is provided with projection 27, the circumferencial direction of this metal fixed base is evenly distributed with at least four perforates 13 that match with projection, nonmetal dustproof cover body 2 and metal fixed base 1 assembling one time-out, nonmetal dustproof cover body 2 places in the metal fixed base 1, and being connected together by projection 27 and perforate 13.Rely on the elasticity of spring sheet that nonmetal dustproof cover body is installed in the metal fixed base easily, and can easily dismantle.
