Abstract

The present invention relates to a stabilizer bar mounting bush which is one of important parts of automobiles. In the conventional mounting bush, a core member and a support hole, which are important constituent elements of a conventional mounting bush, are omitted, and a mounting bush is formed of a rubber- It solved the problem of Bush.

Description

[0001] The present invention relates to a bushing type bushing for mounting a stabilizer bar on a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stabilizer bar mounting bush which is one of important parts of automobiles, and more particularly to a bonding type (adhesive type adhesive) bush which solves the disadvantages of the conventional integrated mounting bush.

As is well known, the stabilizer bar is a kind of torsion spring that supports the rolling phenomenon of the vehicle body caused by the vibration of the vehicle due to the rigidity of the stabilizer bar. The stabilizer bar is mounted on the front and rear wheels of the vehicle, It is an important part to ensure stability in running by keeping left and right balance of the body while suppressing rolling.

The stabilizer bar is connected to the lower control arm or the strut assembly via a control link at each end thereof, and both side portions of the inner side of the stabilizer bar are fixed to the frame by the mounting bushes, And is configured in a rubber bush shape so that the stirrer bar is fixed to the vehicle body or the subframe in such a manner that the slip does not occur when the stirrer bar rotates and a bracket surrounds the rubber bush.

A conventional configuration example of such a stabilizer bar mounting bush is similar to the prior art document and is formed entirely of a rubber material and has a support hole 204 through which a stirrer bar is inserted at the center, The opening 202 is formed so that the stirrer bar can be inserted.

In addition, a core member 210 made of iron is insert-molded in the middle of the thickness of the outer semicircular shape of the support hole 204, and a support hole 240 made of plastic is integrally formed in the lower portion. At the time of installation, the bracket is wrapped around the bush so that the rubber bushing is fixed to the vehicle body while pressing the stirrer bar.

Such a conventional mounting bushing is disadvantageous in that the manufacturing process is complicated and the production cost is increased because the metal core 210 and the plastic support 240 are integrally formed to maintain the compressive force.

In addition, the stiffness is excessively increased in the front-back direction and the vertical direction of the vehicle by the core and the support so that the bushing strength suitable for the vehicle and the strength required by the customer are set low.

And if it is used at a high temperature for a long time, it can not completely prevent the bending phenomenon in the axial direction of the bush. Also, since the thickness of the rubber material increases due to the presence of the core and the base, there is a problem that the mounting distance of the bracket is increased during mounting, and thus a space is required for installation.

Patent Publication Publication 10-2009-0078152

According to the present invention, which is devised in view of the above-described problems, in constructing the stirrer bar mounting bush, the core member and the support hole, which are important constituent elements of the conventional mounting bush, are omitted and the mounting bush is formed of only the rubber- By solving the problems of the conventional bushes, manufacturing is simplified, manufacturing costs are reduced, and rigidity is appropriately manufactured, the stirrer bar is supported with appropriate strength and strength. It is another object of the present invention to improve the installation condition by eliminating the jarring in the axial direction and reducing the mounting distance of the bracket.

In order to accomplish the above object, the present invention provides a mounting bush wherein the interior of the support hole and the stabilizer bar are adhered by an adhesive agent without a core member and a support hole, An adhesive area increasing part protruding within a range not to protrude from the end of the bracket is formed so that the adhesive length is increased and the adhesive area increasing part is slightly protruded by the pressing of the bracket to strongly wrap the stabilizer bar.

Further, according to the present invention, the outer surface of the mounting bush is formed with a bush outer ring having a large thickness and a peripheral flat surface portion having a thin thickness at a portion except for the bottom surface, and the bracket includes a center press- So as to have a uniform stress as a whole.

According to the present invention, in the mounting bushing of the bonding type in which the adhesive is applied and adhered, since the mounting bushes are formed of only the bushes and the brackets made of rubber without the core material and the base, the manufacturing cost is reduced, The stabilizer bar is supported at an appropriate force and strength by being manufactured to have adequate rigidity.

In addition, the jamming phenomenon is eliminated in the axial direction, and the installation distance can be improved by reducing the mounting distance of the bracket.

More specifically, since the adhesion area increasing portion is protruded, the length of adhesion between the stirrer bar and the support hole is increased to obtain an improved adhesive force and a supporting force, and the adhesive force is improved so that the adhesive force is increased for a long time So that the function of the mounting bush as well as the function of the stabilizer bar can be maintained unchanged.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The mounting bush of the present invention is a bush which is installed in a state where the support hole 10 and the stabilizer bar are adhered by an adhesive agent. Like the known mounting bush, the upper part is formed in a semicircular shape and the lower part is formed in a planar shape for fixing And a support hole 10 into which a stirrer bar is inserted is formed at the center.

An adhesive is applied to the support hole 10 and is put in a sticking standby state so as to be adhered to the outer surface of the stirrer bar.

The stabilizer bar 30 is engaged with the support hole 10 and is fixed to the vehicle body by the bracket 20 so that the mounting bar of the rubber material presses the stabilizer bar 30. [

The mounting bush according to the present invention is provided with an adhesive area increasing portion 3 which protrudes from both end edge portions of the support hole 10 and projects beyond the bracket contact end face 2 and does not project beyond the end portion of the bracket 20 Respectively. The adhesion area increasing section 3 is connected to the round section 4 from the end of the bracket contact end face 2 and has a constant thickness t.

 The entire length of the support hole 10 which is made to be in contact with the stirrer bar made by constructing the adhesion area increasing portion 3 is set such that the inner surface of the bracket inner surface including the center press portion 25 and the edge press portion 26, To the total contact length of the outer surface of the bushing which is brought into contact with the bushing. If the length is limited within this range, it is possible to equally stress the joint when the stabilizer bar is engaged, and eventually the mounting bush will exert an equal load and stress on the stirrer bar.

When the mounting bush is fixed to the vehicle body by means of the bracket 20, the bonding area increase part 3 of the mounting bush is pressed by the bracket 20 so that the bonding area increasing part 3 of the mounting bush has its own material more in the longitudinal direction of the stabilizer bar 30 The compressive force is smoothly transmitted along the shape of the round portion 4 so that the length of the portion surrounding the stirrer bar 30 is increased and the stress is distributed evenly throughout the support hole 10 surrounding the outer surface of the stirrer bar . In addition, the protruding portion of the adhesive area increasing portion 3 also functions to strongly press the outer surface of the stirrer bar 30 to prevent foreign matter from entering.

The above-described structure of the present invention can be applied to mounting bushes in which the upper bush 1 and the lower bush 1 'are separated from each other as in the example of the drawings, or an integral type mounting bush or three or more pieces The same can be applied to divided bushes.

In addition, the present invention is applicable to a mounting bush which is composed of only pure rubber material, whether it is a separate type or an integral type, and has a useful action and effect. However, when the core material of iron is applied or the base of synthetic resin material is formed at the same time So that a stronger bonding force can be obtained.

As shown in the figure, an example of a configuration for allowing the adhesion area increasing unit 3 to perform a desired function by effectively pressing the mounting bushes is a bush outer ring (1) having a thicker thickness than the support hole (10) 5 and the edge flat portion 6 having a thinner thickness than that of the edge flat portion 6 are formed on both sides and are connected to the inclined portion 7. The bracket 20 is provided with a central pressing portion 25 for pressing the bush outer ring 5, And the edge pressing portion 26 pressing the portion 6 is formed.

Therefore, when the bracket 20 is coupled to the mounting bushing and fixed to the vehicle body, the central flat surface portion 5 is intensively pressed, so that the stress due to the pressing acts primarily on the central portion and the remaining stress is pushed to the edge side, 6) are added to each other to have an overall uniform stress.

The structure for pressing by such a bracket can be effectively applied even in the case of having the bush outer ring and the edge plane portion as described above, but can be effectively applied even in the case of a bimetal type which is a conventional conventional mounting bush, .

A stress relieving portion 8 is formed at the center of the bush outer ring 5 on the outer surface of the mounting bush so that stress is received or dispersed when the bush outer ring 5 is pressed by the bracket 20 so that the stress is excessively concentrated at the center portion .

The stress relieving portion may be formed as a concave groove type as shown in FIGS. 1 to 7, but it may also constitute a stress relieving portion 8 'protruding as shown in FIG. 8, Is concentrated on the protruding stress relieving portion 8 ', the stress is dispersed to the right and left due to the repulsive force, so that the same stress relieving effect can be obtained. The stress relieving portions 8 and 8 'may have one or two or more symmetrically disposed in the center with a width smaller than the width of the center crimping portion of the bracket.

Since the mounting bush of the present invention has a shape in which the adhesive area increasing portion 3 protrudes, it is very advantageous also in a bonding type in which the stabilizer bar 30 and the supporting hole 10 are bonded with an adhesive agent. Since the adhesive force is improved and the adhesive force is maintained for a long period of time, the function of the mounting bushes as well as the function of the stabilizer bars 30 are maintained It can be.

The mounting bush of the present invention is applied to the outer ring of the bushing 20 when it is combined with the bracket 20 to make it adhere to the outer ring of the bushing 20 and to be bonded when the bracket 20 is engaged with the bushing 20, And damage can be prevented.

Hereinafter, the operation of the mounting bush of the present invention will be described.

The mounting bush of the present invention is assembled with the stabilizer bar 30, which is delivered with the adhesive applied to the inner surface of the support hole 10 and coated on the outer surface with adhesive, and then the vulcanization (pressure and temperature, Adhesion is achieved.

When the bracket 20 is attached to the vehicle body with the stabilizer bar 30 adhered to the support hole 10 of the mounting bush and the bracket 20 is mounted on the vehicle body, the stirrer bar is compressed .

According to a specific embodiment of the drawing, the center press portion 25 and the edge press portion 26 of the bracket 20 press the bush outer ring 5 and the edge plane portion 6 of the mounting bush.

At this time, the stress due to the compression of the outer ring of the bushing acts on the center portion first, the remaining stress is pushed obliquely toward the edge, and the stress due to the compression of the edge plane portion 6 is added, .

Due to such an action, the adhesive area increasing portion 3 of the mounting bushing is slightly pushed further in the lengthwise direction of the stirrer bar 30, so that the length of supporting the stabilizer bar 30 is increased, The more protruding portion of the stabilizer bar 3 strongly presses the stabilizer bar. Therefore, it also serves to prevent foreign matter from flowing between the stirrer bar and the rubber mounting bush.

The stress relieving portion 8 at the center of the outer surface of the bushing outer ring 5 on the outer surface of the mounting bushing receives the stress when the bushing outer ring 5 is pressed by the bracket 20, Thereby preventing excessive concentration.

The present invention can reduce the thickness of the bushes except for the bracket because the mounting bushes are formed of only the bushes made of a rubber material and the brackets made of a metal material without the core material and the base material and accordingly the spacing between the holes for installation in the bracket, ), Which has the advantage of being able to easily minimize the mounting distance (L), which is a critical requirement of the vehicle manufacturer for mounting bushings.
