Description

本発明は防振ブッシュの取付け構造に関する。   The present invention relates to an anti-vibration bush mounting structure.

例えば自動車のサスペンション機構では、サスペンションアームに形成された圧入孔に、内筒と、外筒と、これらの間に介在するゴム状弾性体とから成る防振ブッシュが圧入され、内筒に挿通された取付けボルトを介して内筒が車体側のフレームの一対の挟持部に挟持固定されている。また、内筒の一端部にストッパリングが外嵌し、外筒の一端部側の端面(以下、「一端面」と称する)と前記挟持部とが直接衝突するのをストッパリングで防止している。   For example, in an automobile suspension mechanism, an anti-vibration bush consisting of an inner cylinder, an outer cylinder, and a rubber-like elastic body interposed therebetween is press-fitted into a press-fitting hole formed in a suspension arm and inserted into the inner cylinder. The inner cylinder is clamped and fixed to the pair of clamping portions of the frame on the vehicle body side via the mounting bolts. Also, a stopper ring is fitted on one end of the inner cylinder, and the stopper ring prevents the end face (hereinafter referred to as “one end face”) of the outer cylinder from directly colliding with the clamping part. Yes.

特許文献1に開示されているように、従来、内筒は全長にわたって直胴状に形成されていた。そして、防振ブッシュとストッパリングは、車体側のフレームに組付けられるまで互いに分離した状態になっていた。
特開平11−51099号公報
As disclosed in Patent Document 1, conventionally, the inner cylinder has been formed in a straight barrel shape over the entire length. The anti-vibration bush and the stopper ring were separated from each other until they were assembled to the vehicle body side frame.
JP-A-11-51099

上記従来の構造によれば、防振ブッシュとストッパリングが、車体側のフレームに組付けられるまで互いに分離した状態になっていたために、防振ブッシュとサスペンションアームと車体側のフレームとが同じ場所で組付けられない場合、すなわち、防振ブッシュをサスペンションアームに自動車部品メーカーで取付け、その後に、防振ブッシュ及びサスペンションアームを車体側のフレームに自動車メーカーで組付ける場合、自動車部品メーカー側から自動車メーカー側に運搬する部品の点数が多くなって各部品の管理に手間がかかるという問題があった。   According to the above conventional structure, since the vibration isolating bush and the stopper ring are separated from each other until they are assembled to the vehicle body side frame, the vibration isolating bush, the suspension arm, and the vehicle body side frame are in the same place. In other words, if the anti-shake bushing is attached to the suspension arm by the auto parts manufacturer, and then the anti-shake bush and suspension arm are assembled to the vehicle body side frame by the auto manufacturer, There was a problem that the number of parts to be transported to the manufacturer increased and it took time to manage each part.

本発明の目的は、防振ブッシュをサスペンションアーム等の取付け対象部材に取付けてから、車体側のフレーム等の別の取付け対象部材に取付けるまでの各部品の管理に要する手間を軽減できる防振ブッシュの取付け構造を提供する点にある。   An object of the present invention is to provide an anti-vibration bushing that can reduce the effort required to manage each part from when the anti-vibration bushing is attached to an attachment target member such as a suspension arm to the attachment of another attachment target member such as a frame on the vehicle body side. It is in providing a mounting structure.

本発明の特徴は、
内筒と、外筒と、これらの間に介在するゴム状弾性体とから成る防振ブッシュを、取付け対象部材に形成された圧入孔に圧入するとともに、前記外筒の一端部側の端面よりも前記外筒の軸方向外方側に位置する前記内筒の一端部を、前記外筒の一端部よりも大径のストッパリングに挿通させ、前記内筒の一端部側の端面に押圧具の押圧部を押し付けた状態で、前記押圧具を前記内筒の軸線周りに円錐軌跡を描くように回転させて前記内筒の一端部側の端面を拡張加工し、前記内筒の一端部側の端面の外径を前記ストッパリングの内径よりも大径に設定してある点にある。
The feature of the present invention is that
An anti-vibration bush consisting of an inner cylinder, an outer cylinder, and a rubber-like elastic body interposed between them is press-fitted into a press-fitting hole formed in a member to be attached, and from an end surface on one end side of the outer cylinder Also, one end portion of the inner cylinder positioned on the outer side in the axial direction of the outer cylinder is inserted into a stopper ring having a diameter larger than that of the one end section of the outer cylinder, and a pressing tool is provided on the end surface on the one end section side of the inner cylinder. With the pressing part pressed, the pressing tool is rotated so as to draw a conical locus around the axis of the inner cylinder, and the end face on one end side of the inner cylinder is expanded, and the one end side of the inner cylinder The outer diameter of the end face is set to be larger than the inner diameter of the stopper ring.

上記の構成により、取付け対象部材に防振ブッシュが連結するとともに、防振ブッシュの内筒にストッパリングが連結する。この連結状態で、内筒の一端部側の端面(以下、「一端面」と称する)が拡張加工されており、内筒の一端面の外径がストッパリングの内径よりも大径に設定されているから、ストッパリングが内筒の一端部から抜けなくなる。これにより、例えば、防振ブッシュをサスペンションアーム等の取付け対象部材に部品メーカーで取付け、その後に、防振ブッシュ及び取付け対象部材を車体側のフレーム等の別の取付け対象部材に組み立てメーカーで組付ける場合、部品メーカー側から組み立てメーカー側に運搬する部品の点数を少なくすることができる。   With the above configuration, the vibration isolating bush is coupled to the attachment target member, and the stopper ring is coupled to the inner cylinder of the vibration isolating bush. In this connected state, the end surface on one end side of the inner cylinder (hereinafter referred to as “one end surface”) is expanded, and the outer diameter of the one end surface of the inner cylinder is set larger than the inner diameter of the stopper ring. Therefore, the stopper ring cannot be removed from one end of the inner cylinder. Accordingly, for example, the vibration isolating bush is attached to a mounting target member such as a suspension arm by a parts manufacturer, and then the vibration isolating bush and the mounting target member are assembled to another mounting target member such as a frame on the vehicle body by an assembly manufacturer. In this case, it is possible to reduce the number of parts transported from the part manufacturer side to the assembly manufacturer side.

そして内筒の一端面が拡張していることで、挟持部に圧接する内筒の一端面の面積が大きくなる。その結果、挟持部に作用する内筒からの面圧が小さくなり、挟持部に窪みが生じる不具合を防止できて、挟持力の低下を防止することができる。しかも、内筒の一端面を拡張させる手段として、内筒の一端面に押圧具の押圧部を押し付けた状態で、押圧具を内筒の軸線周りに円錐軌跡を描くように回転させる手段を採用しているから、ゴム状弾性体の自由長を長くすることができる。   And since the one end surface of an inner cylinder is expanded, the area of the one end surface of the inner cylinder which press-contacts to a clamping part becomes large. As a result, the surface pressure from the inner cylinder acting on the sandwiching portion is reduced, so that a problem that a recess is generated in the sandwiching portion can be prevented, and a decrease in the sandwiching force can be prevented. Moreover, as means for expanding the one end surface of the inner cylinder, means for rotating the pressing tool so as to draw a conical locus around the axis of the inner cylinder while the pressing portion of the pressing tool is pressed against the one end surface of the inner cylinder is adopted. Therefore, the free length of the rubber-like elastic body can be increased.

前記ストッパリングがゴム材から成り、前記外筒の他端部に径方向外方側に張り出すフランジが形成され、前記外筒の軸方向外方側を向くフランジ面にストッパゴムが加硫成形されていると、次の作用を奏することができる。つまり、ストッパリングがゴム材から成るから、外筒の一端部と一方の挟持部とが直接衝突するのをストッパリングで防止してその衝撃を十分吸収することができる。また、外筒の他端部に径方向外方側に張り出すフランジが形成され、外筒の軸方向外方側を向くフランジ面にストッパゴムが加硫成形されているから、外筒の他端部と他方の挟持部とが直接衝突するのをストッパゴムで防止してその衝撃を十分吸収することができる。   The stopper ring is made of a rubber material, a flange projecting radially outward is formed at the other end of the outer cylinder, and a stopper rubber is vulcanized on the flange surface facing the axially outer side of the outer cylinder. If it is done, the following effects can be achieved. That is, since the stopper ring is made of a rubber material, the stopper ring can prevent the one end portion of the outer cylinder and the one clamping portion from directly colliding with each other and can sufficiently absorb the impact. Also, a flange projecting radially outward is formed at the other end of the outer cylinder, and a stopper rubber is vulcanized on the flange surface facing the axially outer side of the outer cylinder. The stopper rubber can prevent the end portion and the other clamping portion from directly colliding with each other, and the impact can be sufficiently absorbed.

本発明においては、前記取付け対象部材が自動車のサスペンションアームであり、前記内筒は、この内筒に挿通される取付けボルトを介して、車体側のフレームの一対の挟持部に挟持固定されるよう構成されている構造にすることができる。   In the present invention, the member to be attached is a suspension arm of an automobile, and the inner cylinder is clamped and fixed to a pair of clamping parts of a frame on the vehicle body side via a mounting bolt inserted into the inner cylinder. It can be a structured structure.

本発明によれば、防振ブッシュをサスペンションアーム等の取付け対象部材に取付けてから、車体側のフレーム等の別の取付け対象部材に取付けるまでの各部品の管理に要する手間を軽減でき、しかも、ゴム状弾性体の自由長を長くできてゴム状弾性体の耐久性を上げることができ、各取付け対象部材に対する防振ブッシュの組付け状態を解除されにくくして組付け状態を安定化できる防振ブッシュの取付け構造を提供することができた。   According to the present invention, it is possible to reduce the effort required for managing each part from attaching the vibration isolating bushing to a member to be attached such as a suspension arm to attaching to another member to be attached such as a frame on the vehicle body side, The length of free rubber elastic body can be increased, the durability of the rubber elastic body can be increased, and the assembled state of the anti-vibration bush for each mounting target member is difficult to be released and the assembled state can be stabilized The mounting structure of the vibration bush could be provided.

サスペンションアーム5に取付けられた防振ブッシュ4を、図7に示すように、さらに車体側のフレーム9に取付けてある。すなわち、防振ブッシュ4の内筒1に挿通された取付けボルト10を介して、車体側のフレーム9の一対の挟持板11(挟持部に相当)で挟持固定してある。このように、内筒1は取付けボルト10を介して一対の挟持板11に挟持固定されるよう構成されている。ストッパリング7は、外筒の一端面2Cと挟持板11とが直接衝突するのを防止する手段として設けられ、ストッパゴム16は、外筒2の他端面(フランジ面8C)と挟持板11とが直接衝突するのを防止する手段として設けられている。   As shown in FIG. 7, the vibration isolating bush 4 attached to the suspension arm 5 is further attached to a frame 9 on the vehicle body side. That is, it is clamped and fixed by a pair of clamping plates 11 (corresponding to a clamping part) of the frame 9 on the vehicle body side via a mounting bolt 10 inserted through the inner cylinder 1 of the vibration isolating bush 4. Thus, the inner cylinder 1 is configured to be clamped and fixed to the pair of clamping plates 11 via the mounting bolts 10.
