Abstract
The utility model provides a plate spring rubber bushing which is characterized in that the inner wall of the rubber bushing is uniformly provided with a plurality of horizontal annular grooves. According to the plate spring rubber bushing provided by the utility model, the annular grooves are added on the basis of a typical rubber bushing structure, so as to store superfluous paraffin wax on the inner surface of the bushing during a run-in period, and to solve the abnormal sound problem of the bushing by means of supplementing abraded paraffin wax after a period of abrasion; and changes of the bushing structure are few, and are easy to realize and low in cost.
Description
Technical field
The utility model relates to automobile manufacturing field, is specifically related to a kind of automotive plate spring rubber bush.
Background technology
Automobile is articles for daily use indispensable during people live.The steel spring rubber bush is one of elastic element important on automobile, it is installed in the grasswort at steel spring two ends, rely on the rubber torsional deflection to make grasswort rotate to transform external energy with respect to spring pin, reduce to rub and effectively slow down vibration from ground.The structure of the steel spring rubber bush of present Universal automobile as shown in Figure 1, by bad road or distortion road the time, the rubber bush twist angle is excessive, sleeve surface is its attachment face or fixed surface generation relative displacement relatively, cause rubber bush to produce the friction abnormal sound, be usually use soon will the rubber cracking phenomenon.Not only affected the damping performance of car load, noise is large, has a strong impact on the traveling comfort that client takes.The complex manufacturing of the patent structure that discloses in existing patented technology (with rubber bush and the manufacture method 200810180978.5 thereof of lubricant), productive costs is large, and owing to adopting oily or smectic lubricant to cause its high temperature resistant and low temperature resistant poor performance, in use easily volatilization, cause the service life of lining short, and only cause it to be not suitable for using in eye of spring plate at lining inner peripheral surface coating lubricant.
Summary of the invention
The technical problems to be solved in the utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of novel steel spring rubber bush is provided.
The technical solution adopted in the utility model is:
A kind of steel spring rubber bush is characterized in that: the circular groove that evenly has a plurality of mutual levels on the inwall of described rubber bush.
Further, the technical solution of the utility model can also be:
The degree of depth of described circular groove is 0.8mm; Width is 1.5mm.
Described circular groove has 3.
The inside and outside surface coating of described rubber bush has lubricant layer.
The lubricant material of described lubricant layer is hard paraffin.
The thickness of described lubricant layer is 0.3-0.5mm.
Steel spring rubber bush of the present utility model is on the basis of typical rubber bush structure, by increasing circular groove, can store the unnecessary paraffin of sleeve inner surface at break-in period, solve lining abnormal sound problem in the form that can replenish the paraffin that is worn after wearing and tearing after a while, change to bush structure is less, be easy to realize, with low cost.

The specific embodiment
With reference to accompanying drawing 2-3, will be described in detail the specific embodiment of the present utility model.
Steel spring rubber bush of the present utility model as described in Figure 2 evenly has the circular groove 7 of a plurality of mutual levels on the inwall of rubber bush 2.In this example, circular groove has 3, and its degree of depth is 0.8mm, and width is 1.5mm.
The utility model adopts hard paraffin to replace traditional lubricating oil (silicone oil) or grease (silicone grease), smears the thick hard paraffin of one deck 0.3-0.5mm, formation lubricant layer (not shown) on the inside and outside surface uniform of rubber bush ground.
The assembling of steel spring rubber bush of the present utility model as shown in Figure 3, its setting-up procedure is:
(1) this rubber bush 2 is filled in eye of spring plate 3;
(2) bearing pin 6 on hanger interior plate soldering member 1 is passed the endoporus of rubber bush;
(3) bearing pin passes hanger outer panel 4 then, assembling nut 5 on hanger outer panel outside face, and be screwed to appointment moment, the steel spring rubber bush installs.
Steel spring rubber bush of the present utility model is on the basis of typical rubber bush structure, by increasing circular groove, can store the unnecessary paraffin of sleeve inner surface at break-in period, solve lining abnormal sound problem in the form that can replenish the paraffin that is worn after wearing and tearing after a while, change to bush structure is less, be easy to realize, with low cost.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
