Description

Rubber combined bushing

Technical Field

The utility model belongs to the technical field of the bush, concretely relates to rubber combination bush.

Background

The control arm is used as a guide and force transmission element of an automobile suspension system, transmits various forces acting on the wheel to the automobile body, and simultaneously ensures that the wheel moves according to a certain track. The control arm elastically connects the wheel and the vehicle body through a ball joint or a bushing, respectively. The control arm (including the bushing and ball head associated therewith) should be sufficiently rigid, strong, and durable that the bushing is thereafter more susceptible to damage due to the combined forces of bounce, shear, torsion, and other directions experienced during operation.

SUMMERY OF THE UTILITY MODEL

The prior art is difficult to satisfy people's needs, in order to solve the above-mentioned problem that exists, the utility model provides a rubber combination bush can effectual improvement bush fatigue resistance, prevents that the bush is because under the synthetic force of bearing in service beating, shearing, torsion and other directions, fragile.

In order to achieve the above object, the utility model provides a following technical scheme:

The utility model provides a rubber combination bush, includes inner frame, the rubber body and exoskeleton, the outside of inner frame sets up to the rubber body, the exoskeleton of rubber body assorted exoskeleton is installed in the outside of the rubber body, be equipped with evenly distributed's glass fiber layer on the inner frame, rubber body middle part is equipped with the adjustment tank, both ends all are equipped with fixed connection and assorted regulating plate about the adjustment tank, are located between the regulating plate be equipped with the spring that evenly is central symmetric distribution in the adjustment tank, the upper and lower both ends of spring respectively with corresponding regulating plate between fixed connection.

Preferably, the adjusting tank is internally provided with filling liquid.

Preferably, the adjustment groove is annular.

Preferably, the surface of the rubber body is coated with a wear-resistant coating.

Compared with the prior art, the beneficial effects of the utility model are that:

Utilize the glass fiber layer, can effectively increase the intensity of inner frame, make it satisfy the atress requirement, with internal adjustment tank, regulating plate and the spring of setting up of rubber, utilize the elasticity that the spring is bigger than the rubber body, reduce the deformation volume of the rubber body to the fatigue resistance ability of whole product is improved by a wide margin.

the reference numbers in the figures illustrate: 1-inner framework, 2-rubber body, 3-outer framework, 4-adjusting groove, 5-spring and 6-adjusting plate.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

It should be noted that, in the present invention, when an element is referred to as being "fixed" to another element, it may be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Please refer to fig. 1-2, a rubber combination bushing, includes inner frame 1, rubber body 2 and outer frame 3, the outside of inner frame 1 is set up to rubber body 2, outer frame 3 matched with rubber body 2 is installed in the outside of rubber body 2, be equipped with evenly distributed's glass fiber layer on the inner frame 1, rubber body 2 middle part is equipped with adjustment tank 4, both ends all are equipped with fixed connection and assorted regulating plate 6 about the adjustment tank 4, lie in between the regulating plate 6 be equipped with evenly in the adjustment tank 4 and be the spring 5 of central symmetric distribution, the upper and lower both ends of spring 5 respectively with corresponding between the regulating plate 6 fixed connection.

And filling liquid is arranged in the adjusting groove 4.

The addition of the filling liquid utilizes the hydraulic filling of the liquid, further reduces the deformation amount of the rubber body, and further improves the fatigue resistance of the whole product.

The adjusting groove 4 is annular.

the surface of the rubber body 2 is coated with a wear-resistant coating.

The wear-resistant coating increases the wear resistance of the rubber body 2, thereby improving the overall use performance.

the outer framework 3 is a cylindrical sleeve.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
