According to the shock absorber anti-pressure pad, an integrated structure is adopted, an assembly process is omitted, manpower is saved, and production efficiency is improved; a die can be adopted for processing forming, a process standard is consistent, coaxiality of two components is guaranteed, and the problem that an existing dust cover is inclined and causes abnormal sound is solved; the production cost can be reduced by adopting the rubber material; the integrated structure is adopted, one part variety is reduced, and convenience is brought to purchase, storage, granting and production organization of parts.
Description
Technical field
The utility model relates to a kind of press resistant pillar, particularly relates to a kind of press resistant pillar for vibration damper.
Background technique
Press resistant pillar on vibration damper is an elastic element, utilizes its rigidity to overcome the impact of road surface to vehicle body, improves the smoothness of Vehicle Driving Cycle, improves the travelling comfort that vehicle is taken advantage of seat.When vehicle body is subject to impacting, helical spring is compressed very soon, while causing press resistant pillar to touch vibration damper sealing end, withstands shocks together with helical spring simultaneously.Road shocks load is now born by helical spring and press resistant pillar simultaneously, has effectively slowed down the impact of road surface to vehicle body.
Press resistant pillar is provided with dust-proof cover, and its major function is to prevent that rainwater, silt dust are attached to piston rod surface and oil seal lip in a large number, extends oil sealing working life, avoids vibration damper to occur early failue.
Referring to Fig. 1, press resistant pillar 1 and the dust-proof cover 2 of prior art are separated types, dust-proof cover 2 by and press resistant pillar 1 between interference fit hang on press resistant pillar, the material of dust-proof cover 2 is rubber and plastics, the material of press resistant pillar 1 is polyurethane foam.
The shortcoming of this structure is:
1, press resistant pillar and dust-proof cover be respectively by different materials, different manufacturer production, and the conformity of fitted position precision is poor, makes erecting yard numerous parts cannot meet assembling effect and adopt apolegamy in a large number.
2, due to press resistant pillar and dust-proof cover, use respectively different Mould Machining, machining benchmark is different, and after assembling, coaxality does not reach requirement, makes dust-proof cover crooked, causes itself and surge drum or helical spring friction and produces abnormal sound.
3, because two parts have certain assembling magnitude of interference, the labor intensity of manual assembly is large, makes manufacturing efficiency low.
4,, due to the illusion that is manual assembly, is prone to be seated, in Vehicle Driving Cycle process, occur that separation comes off.Cause dust-proof cover disabler, vibration damper abnormal sound and early stage leakage of oil to lose efficacy.
5, press resistant pillar adopts polyurethane foam, and cushioning effect is better, but cost is higher.
6, dust-proof cover adopts rubber and plastic, and its moulding process is not very stable, after the distortion of tubbiness dust-proof cover, cannot recover.
How to solve the problems of the technologies described above and become the direction that these those skilled in the art make great efforts.
Model utility content
The purpose of this utility model is just to provide a kind of vibration damper press resistant pillar with dust-proof cover, can not only meet assembling quality requirement, and low cost of manufacture, and work efficiency is high, effectively avoids its disabler, thereby solves the problem that above-mentioned prior art exists completely.
The purpose of this utility model realizes by following technical proposals:
A vibration damper press resistant pillar with dust-proof cover, comprises press resistant pillar and dust-proof cover, and described press resistant pillar and dust-proof cover adopt rubber material one-body molded.
This monolithic construction has reduced assembly process one, saves manpower, has improved manufacturing efficiency; And can adopt a set of Mould Machining moulding, technological datum is consistent, thereby guarantees the coaxality of two parts, has solved existing dust-proof cover crooked and cause the problem of abnormal sound; And adopt rubber material to reduce production costs; Adopt monolithic construction, reduced by a component kind, for buying, storage, granting and the organization of production of component have been brought convenience.
Further, described press resistant pillar has the center hole coordinating with piston rod, and center bore inner wall is provided with two annular grooves.
Above-mentioned two annular grooves have increased distortion buffer area (being power absorption zone), thereby extend the working life of press resistant pillar.
Further, the distance between described two annular groove center lines is 4～8mm.
This distance range between above-mentioned two annular grooves makes this press resistant pillar have suitable rigidity.If distance is excessive, can cause annular groove partially narrow, rigidity is less than normal, is unfavorable for improving riding comfort.If distance is too small, can cause annular groove wider, rigidity on the lower side, can not play the effect of elastic element.
Further, other one end outer wall of the relative dust-proof cover of described press resistant pillar is arc-shaped surface.
The demoulding while adopting arc-shaped surface to be conducive to rubber-moulding, and in use arc-shaped surface can disperse stressedly, avoids appearance to ftracture, and is conducive to increase the service life.
Further, the length L of described press resistant pillar is 52mm.
This press resistant pillar adopts length 90mm, 70mm, 52mm to carry out respectively road test after entrucking, finds that the test result that press resistant pillar length is 90mm is two active section necks fractures of press resistant pillar; Press resistant pillar length is that the test result of 70mm is press resistant pillar cracking; When press resistant pillar length is 52mm, the indices of test is all qualified.
Compared with prior art, the beneficial effects of the utility model are:
1. owing to having adopted integrated type, reduce assembly process one, saved manpower, reduced labor strength, greatly improved manufacturing efficiency.
2. avoid the potential failure risk bringing because of manual assembly, played mistake proofing effect, guaranteed assembly quality, reduced rate of fault after sale.
3. monolithic construction is by a set of Mould Machining moulding, and technological datum is the same, has guaranteed the coaxality of part, has solved the abnormal sound problem causing because dust-proof cover is crooked.
4. meeting under the prerequisite of product function, change polyurethane into rubber, reduced product cost, solved the technical problem that cannot recover after dust-proof cover distortion.
5. adopting integrated type, reduce by a part kind, is buying, storage, the granting of part, and organization of production has all been brought convenience.
