Description

この発明は、ラバーブッシュに関し、特に、緩衝器を車両に組付ける際に利用するラバーブッシュの改良に関する。   The present invention relates to a rubber bush, and more particularly to an improvement of a rubber bush used when a shock absorber is assembled to a vehicle.

従来、車両に緩衝器を組付ける際には、走行中の車両において緩衝器からの振動が車体側にそのまま伝播されないようにするために、たとえば、図４に示すように、ラバーブッシュ２０を介して緩衝器Ａと車体Ｂ側とを連結している。   Conventionally, when assembling a shock absorber in a vehicle, in order to prevent vibration from the shock absorber from propagating as it is to the vehicle body side in a traveling vehicle, for example, as shown in FIG. The shock absorber A is connected to the vehicle body B side.

すなわち、油圧緩衝器ＡにおけるピストンロッドＡ１を車体Ｂに開穿のピストンロッド挿通孔Ｂ１に挿通させて連結する場合には、このピストンロッドＡ１が挿入される環状のカラー部材２２に嵌合する一対のラバーブッシュ２０で上記ピストンロッド挿通孔Ｂ１を形成する周辺部Ｂ２を挟持するようにしている。   That is, when the piston rod A1 in the hydraulic shock absorber A is connected to the vehicle body B by being inserted into the opened piston rod insertion hole B1, a pair fitted to the annular collar member 22 into which the piston rod A1 is inserted. The rubber bush 20 sandwiches the peripheral portion B2 that forms the piston rod insertion hole B1.

そして、この一対のラバーブッシュ２０による周辺部Ｂ２の挟持状態を恒久的に維持するために、図４中で上下方向となる、いわゆる、外側から一対のワッシャ２３で当該一対のラバーブッシュ２０を圧縮挟持する。   Then, in order to permanently maintain the sandwiched state of the peripheral portion B2 by the pair of rubber bushes 20, the pair of rubber bushes 20 is compressed by a pair of washers 23 from the outside, which is the vertical direction in FIG. Hold it.

なお、一対のワッシャ２３は、図中で下方となる一方が、たとえば、ピストンロッドＡ１に保持されるバンプクッション（図示せず）の基端部を包むキャップ２４の上端に担持され、図４中で上方となる他方がピストンロッドＡ１の上端螺条部Ａ２に螺着されるナット２５に係止される。   One of the pair of washers 23 on the lower side in the figure is carried on the upper end of a cap 24 that wraps the base end of a bump cushion (not shown) held by the piston rod A1, for example, as shown in FIG. The other upper side is locked by a nut 25 screwed to the upper end threaded portion A2 of the piston rod A1.

したがって、この一対のラバーブッシュ２０を利用して緩衝器Ａを車両に組付けた場合には、ラバーブッシュ２０が撓む範囲内で、たとえば、ピストンロッドＡ１が上下動し得ると共に傾斜することができ、走行中の車両において油圧緩衝器Ａからの振動を車体Ｂ側にそのまま伝播させない、すなわち、衝撃吸収が可能になる。
特開２００３−１３０１２３号公報（発明の詳細な説明の欄，図２） Therefore, when the shock absorber A is assembled to the vehicle using the pair of rubber bushes 20, for example, the piston rod A1 can move up and down and tilt within a range where the rubber bush 20 bends. In other words, the vibration from the hydraulic shock absorber A is not propagated to the vehicle body B as it is in the traveling vehicle, that is, the shock can be absorbed.
JP 2003-130123 A (Detailed Description of the Invention, FIG. 2)

しかしながら、緩衝器Ａを車両に組付ける際、上記した従来のラバーブッシュ２０を利用する場合には、以下の問題がある。   However, when the above-described conventional rubber bush 20 is used when assembling the shock absorber A in the vehicle, there are the following problems.

すなわち、緩衝器Ａの組付けに際しては、一対のラバーブッシュ２０でピストンロッド挿入孔Ｂ１を形成する周辺部Ｂ２を挟持するようにするが、このとき、図４中に示すように、たとえば、下方となるラバーブッシュ２０の一端たる上端に上記の周辺部Ｂ２が当接される態様になるのが通常である。   That is, when assembling the shock absorber A, the peripheral portion B2 that forms the piston rod insertion hole B1 is sandwiched between the pair of rubber bushes 20, but at this time, as shown in FIG. Usually, the above-described peripheral portion B2 is brought into contact with the upper end as one end of the rubber bush 20.

このとき、ラバーブッシュ２０にあっては、図５に示すように、環状の本体２０ｂと、本体２０ｂの一端内周側に外周側より突出して上記のピストンロッド挿入孔Ｂ１に嵌挿される環状の***部２０ａと、***部２０ａの近傍に設けられた溝２０ｃとで構成されており、この***部２０ａがピストンロッド挿入孔Ｂ１に嵌挿されることで、このピストンロッド挿入孔Ｂ１がラバーブッシュ２０の内周側に配在されているカラー部材２２の外周に接触する、いわゆる、メタルタッチ現象を阻止するとしている。   At this time, as shown in FIG. 5, the rubber bush 20 has an annular main body 20 b and an annular main body 20 b that protrudes from the outer peripheral side to one end inner peripheral side and is fitted into the piston rod insertion hole B <b> 1. The raised portion 20a and a groove 20c provided in the vicinity of the raised portion 20a are configured. The raised portion 20a is inserted into the piston rod insertion hole B1, so that the piston rod insertion hole B1 is formed into the rubber bush 20. It is supposed that the so-called metal touch phenomenon that contacts the outer periphery of the collar member 22 disposed on the inner peripheral side of the metal member 22 is prevented.

したがって、上記メタルタッチ現象を防止する為には、***部２０ａは必要不可欠ではある。しかしながら、上記ラバーブッシュ２０の***部２０ａは、カラー部材２２とピストンロッド挿入孔Ｂ１との間に圧縮されて嵌挿され、***部２０ａは圧縮されて変形される。そして、この***部２０ａに作用する圧縮力は、図５に示すように、溝２０ｃで多少緩和するようにはなっているが、***部２０ａは、カラー部材２２とピストンロッド挿入孔Ｂ１との間一杯に嵌挿されているので、どうしても、本体２０ｂと***部２０ａとの接合部分２０ｄに図５中下方へ向けて大きな圧縮力がかかり、場合によっては、この接合部分２０ｄで破断・損傷が生じる危険があると指摘される危惧がある。   Therefore, the raised portion 20a is indispensable to prevent the metal touch phenomenon. However, the raised portion 20a of the rubber bush 20 is compressed and inserted between the collar member 22 and the piston rod insertion hole B1, and the raised portion 20a is compressed and deformed. As shown in FIG. 5, the compressive force acting on the raised portion 20a is somewhat relaxed in the groove 20c, but the raised portion 20a is formed between the collar member 22 and the piston rod insertion hole B1. Since it is fully inserted, a large compressive force is inevitably applied to the joint portion 20d between the main body 20b and the raised portion 20a in the downward direction in FIG. There is a concern that there is a risk of occurring.

したがって、本発明は上記不具合を改善するために創案されたものであって、その目的とするところは、ラバーブッシュの本体と***部の接合部分の破断・損傷を防止することを目的とする。   Accordingly, the present invention has been made to improve the above-described problems, and an object of the present invention is to prevent breakage / damage of the joint portion between the main body and the raised portion of the rubber bush.

上記した目的を達成するために、この発明の課題解決手段は、緩衝器のピストンロッド外周に介装され、一端が車体に開穿されるピストンロッド挿通孔の周辺部に当接するラバーブッシュにおいて、環状の本体と、本体の一端内周側に突出し上記ピストンロッド外周とピストンロッド挿通孔との間にピストンロッドの軸方向に圧縮挿入される環状の***部とを具備してなり、本体の内周側に本体の円周方向に沿う環状の凹部を設けたことを特徴とする。   In order to achieve the above-described object, the problem-solving means of the present invention is a rubber bush that is interposed on the outer periphery of the piston rod of the shock absorber and has one end abutting on the periphery of the piston rod insertion hole that is opened in the vehicle body. An annular main body, and an annular ridge that protrudes toward the inner peripheral side of one end of the main body and is compressed and inserted in the axial direction of the piston rod between the outer periphery of the piston rod and the piston rod insertion hole, An annular recess along the circumferential direction of the main body is provided on the circumferential side.

本発明によれば、ラバーブッシュの本体の内周側に本体の円周方向に沿う環状の凹部を設けたので、ラバーブッシュの***部がピストンロッドとピストンロッド挿入孔との間に圧縮されて嵌挿され変形する際には、上記凹部は、開口状態から転じて閉じた状態に変形し、上記***部に作用する圧縮力が、凹部の変形により緩和されることとなる。したがって、ラバーブッシュが圧縮されても、凹部の変形によりラバーブッシュの本体と***部との接合部分に大きな圧縮力をかけずにすむこととなり、この接合部分でのラバーブッシュの破断・損傷が防止される。   According to the present invention, since the annular recess along the circumferential direction of the main body is provided on the inner peripheral side of the main body of the rubber bush, the raised portion of the rubber bush is compressed between the piston rod and the piston rod insertion hole. When being inserted and deformed, the recess turns from an open state to a closed state, and the compressive force acting on the raised portion is relieved by the deformation of the recess. Therefore, even if the rubber bush is compressed, it is not necessary to apply a large compressive force to the joint between the main part of the rubber bush and the raised part due to the deformation of the recess, and the rubber bush is prevented from being broken or damaged at this joint. Is done.

以下に、図示した実施形態に基づいて、この発明を説明する。図１は、一実施の形態におけるラバーブッシュの締付前の状態を示す縦断面図である。図２は、一実施の形態におけるラバーブッシュの拡大縦断面図である。図３は、一実施の形態におけるラバーブッシュを利用して緩衝器を車体に取付けた状態を示す部分縦断面図である。   The present invention will be described below based on the illustrated embodiments. FIG. 1 is a longitudinal sectional view showing a state before tightening a rubber bush according to an embodiment. FIG. 2 is an enlarged longitudinal sectional view of a rubber bush according to an embodiment. FIG. 3 is a partial longitudinal sectional view showing a state in which the shock absorber is attached to the vehicle body using the rubber bush according to the embodiment.

以下、詳しく説明すると、一実施の形態におけるラバーブッシュ１は、図１に示すように、従来と同様に、いわゆる一対利用とされている。   In the following, the rubber bush 1 according to one embodiment is a so-called paired use as in the prior art, as shown in FIG.

なお、ラバーブッシュ１は、前記した従来の場合と同様に、同じものが互いに反対向きになる状態に配在されてなるとするもので、その意味では、組立時には、単一の形状のものが準備される。   The rubber bushes 1 are arranged in a state in which the same ones are opposite to each other, as in the conventional case described above. Is done.

そして、図１に示すところでは、ピストンロッドＡ１における上端螺条部Ａ２に螺合されるナット５が完全な締付状態になっておらず、したがって、ラバーブッシュ１は、締付のための外力作用を受けておらず、変形されていない状態に維持されている。   In FIG. 1, the nut 5 screwed into the upper end threaded portion A2 of the piston rod A1 is not in a completely tightened state. Therefore, the rubber bush 1 has an external force for tightening. It is not affected and maintained in an undeformed state.

この一対のラバーブッシュ１，１は、図１および図２に示すように、環状の本体１ａと、本体１ａの図１中内周側から突出する環状の***部１ｂと、本体１ａの***部１ｂ外周側近傍に設けられた溝１ｃと、本体の内周側に設けた本体の円周方向に沿う環状の凹部１ｄとで構成されている。   As shown in FIGS. 1 and 2, the pair of rubber bushes 1 and 1 includes an annular main body 1a, an annular raised portion 1b protruding from the inner peripheral side of the main body 1a in FIG. 1, and a raised portion of the main body 1a. 1b is composed of a groove 1c provided in the vicinity of the outer peripheral side and an annular recess 1d provided along the circumferential direction of the main body provided on the inner peripheral side of the main body.

緩衝器Ａは、詳しく図示はしないが、シリンダと、シリンダ内にピストンを介して摺動自在に挿入されるピストンロッドＡ１とを備え、シリンダ内には液体が充填された公知の緩衝器として構成されており、ピストンロッドＡ１の端部には、バンプクッション（図示せず）の基端部を包むキャップ４が取付けられるとともに、その図１中上端には上端螺条部Ａ２が設けられている。また、このピストンロッドＡ１は、筒状のカラー部材２に挿入され、ラバーブッシュ１は、カラー部材２の外周に嵌合される。   Although not shown in detail, the shock absorber A includes a cylinder and a piston rod A1 that is slidably inserted into the cylinder via a piston, and is configured as a known shock absorber that is filled with liquid in the cylinder. A cap 4 that wraps the base end of a bump cushion (not shown) is attached to the end of the piston rod A1, and an upper end thread A2 is provided at the upper end in FIG. . The piston rod A <b> 1 is inserted into the cylindrical collar member 2, and the rubber bush 1 is fitted to the outer periphery of the collar member 2.

また、車体Ｂには、ピストンロッド挿入孔Ｂ１が開穿されており、このピストンロッド挿入孔Ｂ１内に上記緩衝器ＡのピストンロッドＡ１が挿入される。   Further, a piston rod insertion hole B1 is opened in the vehicle body B, and the piston rod A1 of the shock absorber A is inserted into the piston rod insertion hole B1.

さて、緩衝器Ａを車体Ｂに組付けるには、まず、上記したように、ピストンロッドＡ１に環状かつ皿形状のワッシャ３が挿入され、つづいて、ピストンロッドＡ１の外周にカラー部材２を装入し、さらに、カラー部材２の外周に図１中下方に位置されるラバーブッシュ１を嵌合する。   In order to assemble the shock absorber A to the vehicle body B, first, as described above, the annular and dish-shaped washer 3 is inserted into the piston rod A1, and then the collar member 2 is mounted on the outer periphery of the piston rod A1. Further, the rubber bush 1 positioned on the lower side in FIG.

そして、その状態で、ピストンロッドＡ１を車体Ｂのピストンロッド挿入孔Ｂ１内に挿入するが、このとき、下方のラバーブッシュ１の***部１ｂは、ピストンロッド挿入孔Ｂ１とピストンロッドＡ１の外周側に配置されるカラー部材２との間の隙間に入り込むように挿入される。   In this state, the piston rod A1 is inserted into the piston rod insertion hole B1 of the vehicle body B. At this time, the raised portion 1b of the lower rubber bush 1 is on the outer peripheral side of the piston rod insertion hole B1 and the piston rod A1. It is inserted so that it may enter into the gap between the collar member 2 disposed in the space.

さらに、図１中上方に位置されるラバーブッシュ１は、車体Ｂの図１中上方から***部１ｂを図１中下方に向けて、カラー部材２に嵌合され、このとき、上方のラバーブッシュ１の***部１ｂは、ピストンロッド挿入孔Ｂ１とカラー部材２との間の隙間に入り込むように挿入され、上下のラバーブッシュ１，１の***部１ｂ，１ｂは互いに当接した状態となる。すると、上下のラバーブッシュ１，１の本体１ａ，１ａの内周には上記凹部１ｄ，１ｄが設けられているので、本体１ａ，１ａとカラー部材２との間には、図２に示すように、空隙Ｒ，Ｒが形成されることとなる。   Further, the rubber bush 1 positioned at the upper side in FIG. 1 is fitted into the collar member 2 from the upper side of the vehicle body B in FIG. 1 with the raised portion 1b facing downward in FIG. The first raised portion 1b is inserted into the gap between the piston rod insertion hole B1 and the collar member 2, and the raised portions 1b, 1b of the upper and lower rubber bushes 1, 1 are in contact with each other. Then, since the recesses 1d and 1d are provided on the inner circumferences of the main bodies 1a and 1a of the upper and lower rubber bushes 1 and 1, the gaps between the main bodies 1a and 1a and the collar member 2 are as shown in FIG. In addition, voids R and R are formed.

そしてさらに、上方のラバーブッシュ１の上方からピストンロッドＡ１に環状かつ皿形状のワッシャ３が挿入され、そのワッシャ３の上方からピストンロッドＡ１の上端螺条部Ａ２にナット５が螺着される。   Further, an annular and dish-shaped washer 3 is inserted into the piston rod A1 from above the upper rubber bush 1, and a nut 5 is screwed onto the upper end thread portion A2 of the piston rod A1 from above the washer 3.

つぎに、ナット５を上端螺条部Ａ２の螺子溝（付示せず）にそって回転させて下方に移動させて、上下のラバーブッシュ１，１を圧縮変形させて、ラバーブッシュ１，１を締付ることで、図３に示すように、上下のラバーブッシュ１，１がピストンロッド挿入孔Ｂ１を形成する周辺部Ｂ２を挟持することとなるので、これにより緩衝器Ａが車体Ｂに固定される。なお、ナット５は、図３中上方のワッシャ３がカラー部材２に当接することによって上記締付が完了して位置決められる。   Next, the nut 5 is rotated along a screw groove (not shown) of the upper end thread portion A2 and moved downward to compress and deform the upper and lower rubber bushes 1, 1 so that the rubber bushes 1, 1 are moved. By tightening, as shown in FIG. 3, the upper and lower rubber bushes 1 and 1 hold the peripheral portion B2 forming the piston rod insertion hole B1, so that the shock absorber A is fixed to the vehicle body B. Is done. The nut 5 is positioned after the tightening is completed when the upper washer 3 in FIG.

このとき、図３に示すように、上記ナット５の締付により上方に配置されるラバーブッシュ１の***部１ｂには、図３中上方へ向けて圧縮力が作用し、逆に下方に配置されるラバーブッシュ１の***部１ｂには、図３中下方へ向けて圧縮力が作用する。それに伴って、上下のラバーブッシュ１，１の凹部１ｄ，１ｄも圧縮されて変形し、凹部１ｄ，１ｄは、図３中に示すように、開口状態から転じて閉じた状態となる。すなわち、上記凹部１ｄ，１ｄは、それぞれ各空隙Ｒ，Ｒを埋め尽くすように変形する。すると、***部１ｂ，１ｂに作用する圧縮力は、上記凹部１ｄ，１ｄが閉じることによって緩和されることとなる。すなわち、上記凹部１ｄ，１ｄの上記変形により本体１ａ，１ａと***部１ｂ，１ｂとの接合部分１ｅ，１ｅに大きな圧縮力をかけずにすむこととなる。したがって、この接合部分１ｅ，１ｅでのラバーブッシュ１，１の破断・損傷が防止される。   At this time, as shown in FIG. 3, a compressive force acts upward in FIG. 3 on the raised portion 1b of the rubber bush 1 that is disposed upward by tightening the nut 5, and conversely disposed downward. A compression force acts on the raised portion 1b of the rubber bush 1 to be moved downward in FIG. Accordingly, the recesses 1d and 1d of the upper and lower rubber bushes 1 and 1 are also compressed and deformed, and the recesses 1d and 1d are turned from the open state to the closed state as shown in FIG. That is, the recesses 1d and 1d are deformed so as to fill the gaps R and R, respectively. Then, the compressive force acting on the raised portions 1b and 1b is alleviated by closing the concave portions 1d and 1d. That is, the deformation of the concave portions 1d and 1d eliminates the need to apply a large compressive force to the joint portions 1e and 1e between the main bodies 1a and 1a and the raised portions 1b and 1b. Therefore, the rubber bushes 1 and 1 are prevented from being broken and damaged at the joint portions 1e and 1e.

以上で、本発明の実施の形態についての説明を終えるが、本発明の範囲は図示されまたは説明された詳細そのものには限定されないことは勿論である。   This is the end of the description of the embodiment of the present invention, but the scope of the present invention is of course not limited to the details shown or described.
