DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method in which a stopper member made of an elastomer material is bonded to an outer periphery of a rod material with an adhesive in a state of being pressed with a band so as to form a flange,
The present invention relates to a bar preventing structure and a bar preventing method for restricting axial movement of the bar by causing the bar to interfere with a fixing member, and particularly to a bar suitable for use as a stabilizer of a vehicle suspension system. The present invention relates to a structure for preventing a material from shifting and a method for preventing the material from shifting.

2. Description of the Related Art For example, in a stabilizer such as a so-called anti-roll bar used in a vehicle, both ends of a U-shaped bar (stabilizer) which is curved at both ends are bent toward a vehicle body. There is one that supports and holds the distal end of the bending portion to the suspension arm. In general, a rubber bushing wound around a stabilizer is wrapped by a U-shaped stay, and the stay is fixed to the vehicle body with bolts or the like.

However, for example, when a vehicle turns,
Since the opposite phase displacement occurs at the ends of the stabilizers held by the left and right arms, the force in the lateral direction of the vehicle, that is, the axial force at the central portion of the stabilizer is input to the stabilizer, and depending on the magnitude thereof, The rubber bushing and stay cannot suppress it, and the stabilizer will shift sideways, the deformation of the rubber bushing will increase, causing interference with other parts, generating abnormal noise, and damaging the link at the tip of both curved parts of the stabilizer. Not only is there a concern, it also affects the durability and reliability of the stabilizer itself or the ride quality.

In order to prevent the lateral displacement of the stabilizer, for example, there is a method of contacting the rubber bush with the R portion of the stabilizer bar. However, the design is not limited, and the rubber bush and the stabilizer bar may be rubbed. There is a problem in that gravel or the like intrudes between the two, causing abnormal noise, abrasion of the rubber bush, and generation of cracks. Also,
There is also a method of caulking a metal ring to the stabilizer bar by caulking processing or forming a collar by upset processing so as to prevent lateral displacement of the stabilizer so that it is adjacent to the rubber bush.However, the durability of the stabilizer is reduced by scratches and stress concentration. There is a problem of lowering.

[0005] On the other hand, a rubber or resin stopper member is mounted around the stabilizer bar so as to be adjacent to the rubber bush.
There is a method of fixing with a metal band etc., further injecting an adhesive between the stabilizer bar and the slip prevention member, and preventing the lateral displacement of the stabilizer by bonding, there is no need to process the stabilizer bar itself, It is noted that it does not impair the degree of freedom of the stabilizer design.

[0006]

However, since the adhesive is injected between the stabilizer bar and the slip preventing member after the slip preventing member is fastened with the clip band, the adhesive hardly penetrates between the two. When a desired adhesive force, that is, a load in the lateral direction is received, a strength that can withstand the lateral displacement is not necessarily obtained, and there is a problem that the displacement may occur.

Here, it is conceivable to apply an adhesive in advance to the surface of the slip-preventing member to be bonded to the stabilizer bar, but the mounting position is likely to be displaced when tightening with the clip band. However, there is a problem that accurate mounting position accuracy cannot always be obtained.

The present invention has been devised to solve the above-mentioned problems of the prior art, and it is possible to reliably prevent the rod from being displaced with a simple structure, to easily mount the rod, and to obtain a sufficient mounting. An object of the present invention is to provide a structure and a method for preventing displacement of a rod having durability and strength.

[0009]

According to the present invention, there is provided, according to the present invention, a method in which a slip-preventing member made of an elastomer material is bonded to an outer periphery of a rod material with an adhesive in a state of being pressed by a band so as to form an annular shape. A displacement preventing structure of the bar for restricting movement of the bar in the axial direction by interfering with the fixing member; And a guide groove for introducing an adhesive on a surface opposite to the surface is formed on an outer peripheral surface of the rod material, wherein a guide groove for introducing the adhesive is formed. A slip-preventing member made of an elastomer material is annularly mounted, and a band is pressed against the band, and an adhesive is introduced between the outer peripheral surface of the bar and the slip-preventing member through the guide groove to bond the two. Prevention of bar displacement It is achieved by providing law. This structure and method are particularly effective for use in stabilizers for vehicle suspensions.

[0010] With this configuration, after securing the mounting position accuracy of the slip-preventing member, the adhesive surely permeates the surface of the slip-preventing member that is bonded to the bar, and a high slip-resistant load can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the structure of an automobile stabilizer to which the present invention is applied. Rubber bushes 2 and 3 are provided near both curved portions in the center of the stabilizer bar 1 having both ends curved to form a U-shape. The rubber bushes 2 and 3 are not shown by stays 4 and 5 having a U-shape. It is supported at the lower part of the vehicle. The distal end of the curved portion is held by suspension arms 7 and 8 via rubber bushings or the like.
Further, annular stopper members 10 and 11 are annularly mounted at positions adjacent to the rubber bushings 2 and 3 of the stabilizer bar 1. Since these stopper members 10 and 11 have the same structure, the stopper member 10 will be described below.
A detailed description of the slip stopper 11 will be omitted.

As shown in FIG. 2 which is an enlarged view of a main part of FIG. 1, the slip preventing member 10 is made of an elastomer material such as rubber or other resin, and is an annular main body mounted around the stabilizer bar 1. 13 and a clip band 14 for fastening the main body 13 to the stabilizer bar 1 so as to be pressed. An adhesive is injected between the main body 13 and the stabilizer bar 1 to bond the two.

When a force is applied to the stabilizer 1 in the lateral direction, that is, in the axial direction of the central portion of the stabilizer 1, the rubber bushings 2, 3 and the stays 4, 5 are moved by the slip preventing members 10, 11. , 11 to prevent lateral displacement.

Here, as shown in FIG. 3, a large number of adhesive guide grooves 13a and 13b are formed on the contact surface (adhesion surface) of the main body 13 with the stabilizer bar 1 in the vertical and horizontal directions. Of these, the guide groove 13a is a groove extending in the axial direction of the stabilizer bar 1, and the guide groove 13b is a guide groove 13
The groove is orthogonal to a, that is, extends in the circumferential direction of the stabilizer bar 1. By the guide grooves 13a and 13b, the bonding area between the main body 13 and the stabilizer bar 1 is remarkably increased as compared with the conventional one having no guide groove, and both are firmly bonded.

The procedure for assembling the slip stopper 10 will be described below. First, the main body 13 is mounted around the stabilizer bar 1, positioned, and the clip band 14 is tightened.
Next, an adhesive is injected from one axial end of the main body 13 and solidified. At this time, the adhesive is guided inward by the guide groove 13a extending in the axial direction of the stabilizer bar 1,
It is turned around in the circumferential direction by the guide groove 13b, and
3 penetrates over the entire bonding surface of the stabilizer bar 1.

In this embodiment, the guide groove of the adhesive formed on the main body 13 extends in the axial direction and the circumferential direction of the stabilizer bar 1, but either one or both grooves intersect each other. The shape is not limited, for example, it may be formed to extend obliquely in the circumferential direction, or may be formed in a spiral shape.

EXAMPLE A slip-preventing member consisting of a rubber body and a stainless steel clip band was attached to an iron rod of the same material and of the same diameter in the procedure described in the above embodiment, and a load resistance test was carried out. Here, the diameter of the iron bar was 22 mm, the inner diameter of the rubber body was 21.7 mm, the outer diameter of the clip band fastening portion of the rubber body was 27 mm, and the inner diameter of the clip band after fastening was 27.5 mm. As a comparative example A, a guide groove was formed in a rubber body and no adhesive was injected, and as a conventional example B, a guide groove was not formed in a rubber body,
The same test was conducted for the case where no adhesive was injected and the case where the adhesive was injected without forming a guide groove in the rubber body as Conventional Example C. The results are shown in Table 1 below and the graph of FIG.

[0019]

[Table 1]

As shown in this table and FIG. 4, there is a correlation between the displacement load resistance and the bonding area, and when the guide groove is formed in the rubber body and the adhesive is injected, the bonding area is reduced. Is remarkably large, and it is understood that an extremely good displacement resistance is shown.

[0021]

As is apparent from the above description, according to the bar displacement prevention structure and the bar displacement prevention method according to the present invention, it is possible to use an elastomer material which is mounted on the outer periphery of the bar material and fastened with a band. A guide groove for introducing an adhesive is formed on the contact surface of the stopper member with the bar member, and the adhesive is introduced between the outer peripheral surface of the bar member and the stopper member through this guide groove, With a simple structure and method of permeating and bonding both, the bonding area is increased, the slip prevention member is firmly fixed to the bar, and a high slip resistance can be stably obtained.
