Description

本発明は、
筒状のゴムブッシュの嵌合部をスタビライザーバーの被嵌合部に外嵌固着してゴムブッシュ付きスタビライザーバーを製造するゴムブッシュ付きスタビライザーバーの製造方法に関する。 The present invention
The present invention relates to a method for manufacturing a stabilizer bar with a rubber bush, in which a fitting portion of a cylindrical rubber bush is externally fixed to a fitted portion of a stabilizer bar to manufacture a stabilizer bar with a rubber bush.

一般に、ゴムブッシュ付きスタビライザーバーは、スタビライザーバーをゴムブッシュに挿通させただけの構造になっている。そして、一対の取付けブラケットでゴムブッシュをスタビライザーバーとともに挟圧して車体側に取付け固定してある。ところが、この構造では、ゴムブッシュとスタビライザーバーの間に水が浸入したときや気温が非常に低温になったときに、ゴムブッシュがスタビライザーバーに対してスリップして異音が発生しやすかった。この問題を解消するために、従来、
（１）スタビライザーバーの被嵌合部の被嵌合面に接着剤を塗布し、
（２）ゴムブッシュの嵌合部をスタビライザーバーの被嵌合部に外嵌し、
（３）一対の挟圧部材でゴムブッシュを径方向に挟圧し、この挟圧状態のゴムブッシュ及びスタビライザーバーを加熱用のオーブンに収容し、
（４）ゴムブッシュの全体を径方向外方側から加熱して接着剤の接着反応を生じさせる方法があった。 Generally, a stabilizer bar with a rubber bush has a structure in which the stabilizer bar is simply inserted through the rubber bush. And a rubber bush is clamped with a stabilizer bar with a pair of mounting brackets, and is fixed to the vehicle body. However, in this structure, when water enters between the rubber bush and the stabilizer bar or when the air temperature becomes very low, the rubber bush easily slips with respect to the stabilizer bar and noise is likely to occur. To solve this problem,
(1) Apply adhesive to the mating surface of the mating part of the stabilizer bar,
(2) Fit the fitting part of the rubber bush to the fitted part of the stabilizer bar,
(3) The rubber bush is clamped in the radial direction by a pair of clamping members, and the rubber bush and the stabilizer bar in the clamped state are accommodated in a heating oven,
(4) There has been a method of causing the adhesive reaction of the adhesive by heating the entire rubber bush from the radially outer side.

しかしながら、上記従来の技術によれば異音の発生を防止できるものの、上記の（４）の工程で加熱に２０分〜３０分かかって生産性を上げることが困難であった。そして、ゴムブッシュの全体をゴムブッシュの径方向外方側から加熱するために、ゴムブッシュが熱で劣化して所望の特性を発揮しにくくなることがあった。   However, according to the conventional technique, although the generation of abnormal noise can be prevented, it has been difficult to increase the productivity in the process (4) because the heating takes 20 to 30 minutes. In addition, since the entire rubber bush is heated from the radially outer side of the rubber bush, the rubber bush may deteriorate due to heat, making it difficult to exhibit desired characteristics.

本発明は上記実状に鑑みて成されたもので、その目的は、異音を防止できる構造でありながら、生産性を上げることができるとともに、加熱によるゴムブッシュの劣化等の不具合を回避できて、ゴムブッシュが所望の特性を発揮しやすいゴムブッシュ付きスタビライザーバーを製造できるようにする点にある。   The present invention has been made in view of the above circumstances, and its purpose is to prevent the generation of abnormal noise while improving productivity and avoiding problems such as deterioration of the rubber bush due to heating. The rubber bush is capable of producing a stabilizer bar with a rubber bush that easily exhibits desired characteristics.

本発明の特徴は、
筒状のゴムブッシュの嵌合部をスタビライザーバーの被嵌合部に外嵌固着してゴムブッシュ付きスタビライザーバーを製造するゴムブッシュ付きスタビライザーバーの製造方法であって、
前記ゴムブッシュの嵌合部の嵌合面と前記スタビライザーバーの被嵌合部の被嵌合面との少なくとも一方に接着剤を塗布する接着剤塗布工程と、
前記ゴムブッシュの嵌合部をスタビライザーバーの被嵌合部に外嵌する嵌合工程と、
一対の挟圧部材で前記ゴムブッシュを径方向に挟圧した状態で、前記ゴムブッシュの軸芯方向両外方側のスタビライザーバー部分を高周波誘導加熱することで、前記被嵌合面を加熱するとともに前記嵌合面を前記被嵌合面側から加熱して、前記接着剤の接着反応を生じさせる高周波誘導加熱工程とから成り、
前記挟圧部材は、前記ゴムブッシュを車体側に取付け固定するための取付けブラケットであり、
前記ゴムブッシュは、互いに別体の断面半円形リング状の一対のゴムブッシュ部分から成り、前記接着剤塗布工程に入る前に、一方のゴムブッシュ部分の外周部を、一方の取付けブラケットに形成した凹部に加硫接着しておくとともに、他方のゴムブッシュ部分の外周部を、他方の取付けブラケットに形成した凹部に加硫接着しておく点にある。
The feature of the present invention is that
A method for manufacturing a stabilizer bar with a rubber bush, in which a fitting portion of a cylindrical rubber bush is externally fixed to a fitted portion of a stabilizer bar to manufacture a stabilizer bar with a rubber bush,
An adhesive application step of applying an adhesive to at least one of the fitting surface of the fitting portion of the rubber bush and the fitted surface of the fitted portion of the stabilizer bar;
A fitting step of externally fitting the fitting portion of the rubber bush to the fitted portion of the stabilizer bar;
In a state where the rubber bush is clamped in a radial direction by a pair of clamping members, the fitting surface is heated by high-frequency induction heating the stabilizer bar portions on both outer sides in the axial direction of the rubber bush. heating said mating surface from the fitting target surface with, Ri consists the high frequency induction heating step to cause adhesion reaction of the adhesive,
The clamping member is a mounting bracket for mounting and fixing the rubber bush to the vehicle body side ,
The rubber bush is composed of a pair of semi-circular ring-shaped rubber bush portions separated from each other, and before entering the adhesive application step, the outer peripheral portion of one rubber bush portion is formed on one mounting bracket. In addition to being vulcanized and bonded to the concave portion, the outer peripheral portion of the other rubber bush portion is vulcanized and bonded to the concave portion formed in the other mounting bracket .

この手段によれば、高周波誘導加熱する時間が一般に短くて済むことから（一例として１０秒〜３分）作業効率を上げることができる。また、ゴムブッシュの軸芯方向両外方側のスタビライザーバー部分を高周波誘導加熱することで、前記被嵌合面を加熱するとともに前記嵌合面を被嵌合面側から加熱するから、ゴムブッシュの全体をそのゴムブッシュの径方向外方側から加熱する従来の手段に比べると、ゴムブッシュにかかる負担を軽減できてゴムブッシュの劣化等の不具合を回避できる。そして、一対の挟圧部材でゴムブッシュを径方向に挟圧するから接着性をよくすることができる。（請求項１）   According to this means, since the time for high-frequency induction heating is generally short (as an example, 10 seconds to 3 minutes), work efficiency can be increased. Further, since the stabilizer bar portions on both outer sides in the axial direction of the rubber bush are subjected to high-frequency induction heating, the fitted surface is heated and the fitted surface is heated from the fitted surface side. Compared to the conventional means for heating the whole of the rubber bush from the radially outer side of the rubber bush, the burden on the rubber bush can be reduced and problems such as deterioration of the rubber bush can be avoided. And since a rubber bush is clamped to radial direction with a pair of clamping member, adhesiveness can be improved. (Claim 1)

The rubber bush is composed of a pair of semi-circular ring-shaped rubber bush portions separated from each other, and before entering the adhesive application step, the outer peripheral portion of one rubber bush portion is formed on one mounting bracket. When vulcanized and bonded to the recess, and the outer peripheral portion of the other rubber bushing is vulcanized and bonded to the recessed portion formed on the other mounting bracket, the rubber bush is clamped in the radial direction by the pair of mounting brackets. At this time, positioning between one mounting bracket and one rubber bush portion and positioning between the other mounting bracket and the other rubber bush portion can be made unnecessary. (Claim 1 )

(3) Fitting process The first fitting portion 26 on one rubber bush portion 6 side is externally fitted to the fitted portion 5 of the stabilizer bar 4, and the second fitting portion 27 on the other rubber bush portion 7 side is fitted. It fits to the fitted part 5. That is, the fitting portion 3 of the rubber bush 1 is externally fitted to the fitted portion 5 of the stabilizer bar 4. The first fitting portion 26 and the second fitting portion 27 are tightly fitted (tightly fitted) to the fitted portion 5.
(4) High-frequency induction heating process As shown in FIG. 4, the rubber bush 1 is clamped in the radial direction by a pair of mounting brackets 2A and 2B. One surface 11 (surface orthogonal to the bolt insertion hole 9) of one mounting bracket 2A and one surface 12 (surface orthogonal to the bolt insertion hole 9) of the other mounting bracket 2B face each other with a predetermined first gap S1 therebetween. The circumferential end surface of one rubber bush portion 6 and the circumferential end surface of the other rubber bush portion 7 are opposed to each other with a predetermined second gap S2. The second gap S2 has a triangular shape spreading outward in the radial direction when the rubber bush 1 is viewed in the axial direction. As shown in FIG. 5 to FIG. 7, the stabilizer bar portion 13 on both outer sides J1 in the axial direction of the rubber bush 1 is connected to the coil portion 14 of the high frequency induction heating device in the above-described clamping state. Enter from K2. The coil portion 14 is formed of a copper pipe 15 and is formed in a C shape when viewed in the axial direction so as to receive a pair of stabilizer bar portions 13 from the radially outward K2 side. Next, current is passed through the coil portion 14 to heat the pair of stabilizer bar portions 13 by high-frequency induction heating, thereby heating the mating surface 30 and the mating surface 23 (the first mating surface portion 28 and the second mating surface portion 2). The fitting surface portion 29) is heated from the mating surface 30 side (see FIGS. 4 (a) and 4 (b)), and the adhesive is bonded without heating the rubber bush 1 from the radially outer side. Cause a reaction. The current flow time is 2 minutes. In 2 minutes, the temperature of the mating surface 30 is raised to 180 ° C. Even after the current stops flowing through the coil portion 14, the rubber bushing 1 is continuously clamped by the pair of mounting brackets 2A and 2B, and the clamping pressure is released when a predetermined time has elapsed. Even after releasing the clamping pressure, the one surface 11 of one mounting bracket 2A and the one surface 12 of the other mounting bracket 2B face each other with a predetermined gap S therebetween.

車体Ｆ側に組付けるときは、ボルト挿通孔９に取付けボルト（図示せず）を挿通させて車体Ｆ側の雌ねじ部に螺合締結する。これにより、一方の取付けブラケット２Ａの前記一面１１と、他方の取付けブラケット２Ｂの前記一面１２とが、互いに近づいてゴムブッシュ１が圧縮された状態でスタビライザーバー４とともに車体Ｆ側に取付けられる（図１（ａ），図１（ｂ）参照）。   When assembled on the vehicle body F side, a mounting bolt (not shown) is inserted into the bolt insertion hole 9 and screwed to the female screw portion on the vehicle body F side. As a result, the one surface 11 of one mounting bracket 2A and the one surface 12 of the other mounting bracket 2B approach each other and are attached to the vehicle body F side together with the stabilizer bar 4 in a state where the rubber bush 1 is compressed (see FIG. 1 (a), see FIG. 1 (b)).
