Abstract
The invention discloses a steel sleeve for a damper. The steel sleeve for the damper comprises a steel sleeve body, an antimony plating layer, a vanadium plating layer, a damping built-in layer, a damping layer and an abrasion resistance metal plating layer. The inner wall of the steel sleeve body is sequentially provided with the damping built-in layer and the damping layer, the antimony plating layer is arranged on the outer wall of the steel sleeve body, the vanadium plating layer is arranged on the outer surface of the antimony plating layer, and the abrasion resistance metal plating layer is arranged on the outer surface of the vanadium plating layer. The steel sleeve for the damper is provided with the damping built-in layer, the damping layer and the abrasion resistance metal plating layer, the functions of buffering and damping are achieved, the abrasion resistance performance is good, damage can not happen easily, and the service life is long.
Description
Technical field
The present invention relates to Steel Sleeve field, particularly relate to a kind of Steel Sleeve for vibration damper.
Background technique
Concussion when vibration damper is mainly used to suppress rebound after spring shock-absorbing and from the impact on road surface, when through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, therefore the harder vibration damper of the general employing of heavier car.
Yet the existing Steel Sleeve for vibration damper does not possess bumper and absorbing shock function, abrasion resistance properties is poor, easily damages, and working life is short.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Steel Sleeve for vibration damper, possesses bumper and absorbing shock function, and abrasion resistance properties is good, not fragile, long service life.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of Steel Sleeve for vibration damper is provided, comprise: Steel Sleeve body, antimony plating layer, plating vanadium layer, buffering build-up layer, buffer layer and wear-resistant metal coating, on the inwall of described Steel Sleeve body, be disposed with described buffering build-up layer and described buffer layer, on the outer wall of described Steel Sleeve body, be provided with described antimony plating layer, on the outer surface of described antimony plating layer, be provided with described plating vanadium layer, on the outer surface of described plating vanadium layer, be provided with described wear-resistant metal coating.
In a preferred embodiment of the present invention, the aperture of described Steel Sleeve body is 3 ~ 10 cm.
In a preferred embodiment of the present invention, the thickness of described Steel Sleeve body is 8 ~ 15 mm.
In a preferred embodiment of the present invention, described wear-resistant metal coating is nickel-cobalt alloy plating, Perminvar coating or ferronickel tungsten alloy coating.
The invention has the beneficial effects as follows: the present invention is provided with buffering build-up layer, buffer layer and wear-resistant metal coating, possesses bumper and absorbing shock function, and abrasion resistance properties is good, not fragile, long service life.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of Steel Sleeve for vibration damper, comprise: Steel Sleeve body, antimony plating layer, plating vanadium layer, buffering build-up layer, buffer layer and wear-resistant metal coating, on the inwall of described Steel Sleeve body, be disposed with described buffering build-up layer and described buffer layer, on the outer wall of described Steel Sleeve body, be provided with described antimony plating layer, on the outer surface of described antimony plating layer, be provided with described plating vanadium layer, on the outer surface of described plating vanadium layer, be provided with described wear-resistant metal coating.
In addition, the aperture of described Steel Sleeve body is 3 ~ 10 cm.
In addition, the thickness of described Steel Sleeve body is 8 ~ 15 mm.
In addition, described wear-resistant metal coating is nickel-cobalt alloy plating, Perminvar coating or ferronickel tungsten alloy coating.
The present invention for the beneficial effect of the Steel Sleeve of vibration damper is: the present invention is provided with buffering build-up layer, buffer layer and wear-resistant metal coating, possesses bumper and absorbing shock function, and abrasion resistance properties is good, not fragile, long service life.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
