Description

サスペンション装置Suspension device
　本発明は、サスペンション装置に関する。 The present invention relates to a suspension device.
　ショックアブソーバのまわりに同心円状に配設されるコイルスプリングを備えたストラット型のダンパ（サスペンション装置）が知られている（ＵＳ２０１６００２３５２９Ａ１参照）。コイルスプリングは、ダンパのアッパースプリングシートとロアスプリングシートとの間に配置される。ロアスプリングシート（スプリングガイド）は、コイルスプリングを支持する環状部材と、環状部材から延在する管状部材と、を備える。管状部材は、ショックアブソーバのアウターチューブの周囲に配置される。管状部材の端部は、アウターチューブに溶接された支持リングに当接する。 A strut-type damper (suspension device) having coil springs arranged concentrically around a shock absorber is known (see US20160023529A1). The coil spring is arranged between the upper spring seat and the lower spring seat of the damper. The lower spring seat (spring guide) includes an annular member that supports the coil spring, and a tubular member that extends from the annular member. The tubular member is arranged around the outer tube of the shock absorber. The end of the tubular member abuts a support ring welded to the outer tube.
　ＵＳ２０１６００２３５２９Ａ１に記載のサスペンション装置は、スプリングガイドがコイルスプリングと支持リングとの間で挟まれた状態で使用される。このため、サスペンション装置の使用中に、スプリングガイドがショックアブソーバのシリンダから外れてしまうことはない。 The suspension device described in US20160023529A1 is used with the spring guide sandwiched between the coil spring and the support ring. Therefore, the spring guide does not come off the cylinder of the shock absorber during use of the suspension device.
　しかしながら、サスペンション装置を組み立てる際、ショックアブソーバのシリンダにスプリングガイドを嵌合させた状態であって、コイルスプリングが取り付けられる前の状態では、スプリングガイドに外力が作用することにより、スプリングガイドがショックアブソーバから外れてしまうおそれがある。その結果、サスペンション装置の組み立て作業の効率が悪化するおそれがある。 However, when assembling the suspension device, when the spring guide is fitted to the cylinder of the shock absorber, and before the coil spring is attached, external force acts on the spring guide, so that the spring guide is attached to the spring guide. There is a risk of coming off. As a result, the efficiency of the assembly work of the suspension device may deteriorate.
　本発明は、サスペンション装置の組み立て作業の効率を向上することを目的とする。 The present invention aims to improve the efficiency of the assembly work of the suspension device.
　本発明のある態様によれば、サスペンション装置であって、シリンダと前記シリンダから突出するロッドとを有し、車体と車輪との間に設けられるショックアブソーバと、前記ロッドの先端に取り付けられるアッパーマウントと、前記シリンダの外周面に取り付けられるスプリングガイドと、前記スプリングガイドと前記アッパーマウントとの間に設けられ、前記車体を弾性支持するコイルスプリングと、前記シリンダの端部に取り付けられるバンプキャップと、前記ロッドに取り付けられ、前記ショックアブソーバが所定量だけ収縮したときに前記バンプキャップに当たることにより前記ショックアブソーバの縮み側のストロークを規制するバンプストッパと、を備え、前記スプリングガイドは、前記ショックアブソーバが挿通する挿通孔を有し、前記バンプキャップは、前記スプリングガイドに当接し前記スプリングガイドの軸方向の移動を規制する規制部を有する。 According to an aspect of the present invention, there is provided a suspension device including a cylinder and a rod protruding from the cylinder, the shock absorber provided between a vehicle body and a wheel, and an upper mount attached to a tip of the rod.

　図面を参照して、本発明の実施形態に係るサスペンション装置１０について説明する。 A suspension device 10 according to an embodiment of the present invention will be described with reference to the drawings.
　図１は、サスペンション装置１０の部分断面図である。図１に示すように、サスペンション装置１０は、自動車（図示せず）に取り付けられ、車輪（図示せず）を位置決めするとともに減衰力を発生させて車両走行中に路面から受ける衝撃や振動を吸収して車体を安定的に懸架する装置である。 FIG. 1 is a partial cross-sectional view of the suspension device 10. As shown in FIG. 1, a suspension device 10 is attached to an automobile (not shown) to position wheels (not shown) and generate a damping force to absorb shocks and vibrations received from a road surface while the vehicle is running. It is a device that stably suspends the vehicle body.
　サスペンション装置１０は、車体と車輪との間に設けられるストラット式のショックアブソーバ１と、ショックアブソーバ１のピストンロッド（以下、ロッドと記す）１ａの先端に取り付けられるアッパーマウント２と、ショックアブソーバ１のシリンダ１ｂの外周面に取り付けられるスプリングガイド１００と、スプリングガイド１００とアッパーマウント２との間に設けられ、車体を弾性支持するコイルスプリング４と、ロッド１ａに嵌装されショックアブソーバ１の縮み側のストロークを規制するバンプストッパ５と、シリンダ１ｂのロッド１ａ側の端部に嵌装されるキャップ部材としてのバンプキャップ１６０と、ロッド１ａを保護する筒状のカバー部材としてのダストブーツ７と、を備える。 The suspension device 10 includes a strut-type shock absorber 1 provided between a vehicle body and wheels, an upper mount 2 attached to a tip of a piston rod (hereinafter, referred to as a rod) 1a of the shock absorber 1, and a shock absorber 1 of the shock absorber 1. A spring guide 100 attached to the outer peripheral surface of the cylinder 1b, a coil spring 4 provided between the spring guide 100 and the upper mount 2 for elastically supporting the vehicle body, and a compression side of the shock absorber 1 fitted on the rod 1a. A bump stopper 5 for restricting the stroke, a bump cap 160 as a cap member fitted to the end portion of the cylinder 1b on the rod 1a side, and a dust boot 7 as a tubular cover member for protecting the rod 1a are provided. Prepare
　ショックアブソーバ１は、シリンダ１ｂと、シリンダ１ｂの開口部１４２（図３参照）から突出する円柱状のロッド１ａと、を有する。ショックアブソーバ１は、複筒型のショックアブソーバであり、シリンダ１ｂは、シリンダ１ｂの外郭を構成する有底円筒状のアウターチューブ１１ｏと、アウターチューブ１１ｏの内側に設けられるインナーチューブ１１ｉ（図３参照）と、を有する。ロッド１ａの下端部には、インナーチューブ１１ｉ内を伸側室と圧側室とに区画するピストン（不図示）が連結されている。 The shock absorber 1 has a cylinder 1b and a cylindrical rod 1a protruding from an opening 142 (see FIG. 3) of the cylinder 1b. The shock absorber 1 is a double-cylinder type shock absorber, and the cylinder 1b has a bottomed cylindrical outer tube 11o that forms an outer shell of the cylinder 1b and an inner tube 11i provided inside the outer tube 11o (see FIG. 3). ), and have. A piston (not shown) that divides the inner tube 11i into an expansion side chamber and a compression side chamber is connected to the lower end of the rod 1a.
　ロッド１ａは、アウターチューブ１１ｏの開口端部に設けられるロッド保持部１４５（図３参照）により、摺動自在に支持される。ロッド保持部１４５は、ダストシール、オイルシール、軸受等が積層された積層構造とされる。ロッド保持部１４５及びインナーチューブ１１ｉは、アウターチューブ１１ｏの上端部を内側にかしめることにより形成されるかしめ部１４１（図３参照）と、アウターチューブ１１ｏの底部とによって軸方向に挟持される。 The rod 1a is slidably supported by a rod holding portion 145 (see FIG. 3) provided at the open end of the outer tube 11o. The rod holding portion 145 has a laminated structure in which a dust seal, an oil seal, a bearing and the like are laminated. The rod holding portion 145 and the inner tube 11i are axially clamped by a caulking portion 141 (see FIG. 3) formed by crimping the upper end portion of the outer tube 11o inward and the bottom portion of the outer tube 11o.
　図１に示すように、シリンダ１ｂのロッド１ａ側とは反対側の端部には、車輪を保持するハブキャリア（図示せず）とショックアブソーバ１とを連結するためのブラケット１ｃが設けられる。説明の便宜上、アッパーマウント２側をサスペンション装置１０の上側、ブラケット１ｃ側をサスペンション装置１０の下側として上下方向を図示するように規定する。なお、サスペンション装置１０の上下方向は、サスペンション装置１０の軸方向（中心軸方向）であり、ショックアブソーバ１の伸縮方向である。また、サスペンション装置１０の径方向（ショックアブソーバ１の径方向）は、サスペンション装置１０の軸方向に直交する。 As shown in FIG. 1, a bracket 1c for connecting a hub carrier (not shown) holding a wheel and the shock absorber 1 is provided at the end of the cylinder 1b opposite to the rod 1a side. For convenience of explanation, the upper mount 2 side is defined as the upper side of the suspension device 10 and the bracket 1c side is defined as the lower side of the suspension device 10 and the vertical direction is defined as shown in the figure. The vertical direction of the suspension device 10 is the axial direction (center axis direction) of the suspension device 10 and the expansion/contraction direction of the shock absorber 1. The radial direction of the suspension device 10 (the radial direction of the shock absorber 1) is orthogonal to the axial direction of the suspension device 10.
　ショックアブソーバ１は、アッパーマウント２を介して車体に連結されるとともに、ブラケット１ｃによりハブキャリアに連結されて車両に組み付けられる。このように構成されたショックアブソーバ１は、ロッド１ａがシリンダ１ｂに対して軸方向（図１の上下方向）に移動したときに、減衰力が発生するように構成されている。サスペンション装置１０は、このショックアブソーバ１の減衰力によって車体の振動を素早く減衰させる。 The shock absorber 1 is connected to the vehicle body via the upper mount 2 and is also attached to the vehicle by being connected to the hub carrier by the bracket 1c. The shock absorber 1 configured as described above is configured to generate a damping force when the rod 1a moves in the axial direction (vertical direction in FIG. 1) with respect to the cylinder 1b. The suspension device 10 quickly damps the vibration of the vehicle body by the damping force of the shock absorber 1.
　コイルスプリング４は、アッパーマウント２とスプリングガイド１００との間に圧縮状態で挟持され、ショックアブソーバ１を伸長方向に付勢する。アッパーマウント２とコイルスプリング４との間にはラバーシート８が設けられる。これにより、アッパーマウント２とコイルスプリング４とが直接当接しないようになっている。スプリングガイド１００とコイルスプリング４との間には円弧状のラバーシート４０が設けられる。これにより、スプリングガイド１００とコイルスプリング４とが直接当接しないようになっている。 The coil spring 4 is sandwiched in a compressed state between the upper mount 2 and the spring guide 100, and urges the shock absorber 1 in the extension direction. A rubber sheet 8 is provided between the upper mount 2 and the coil spring 4. As a result, the upper mount 2 and the coil spring 4 do not come into direct contact with each other. An arc-shaped rubber sheet 40 is provided between the spring guide 100 and the coil spring 4. This prevents the spring guide 100 and the coil spring 4 from directly contacting each other.
　図２は、スプリングガイド１００の斜視図である。図１及び図２に示すように、スプリングガイド１００は、シリンダ１ｂの外周に固定される樹脂製の皿状の部材である。スプリングガイド１００は、コイルスプリング４を支持する円板状のベース部１１０と、ベース部１１０の外縁から上側（アッパーマウント２側）に延在する側壁１１１と、ベース部１１０をサスペンション装置１０の軸方向（上下方向）に貫通するように設けられ、ショックアブソーバ１のシリンダ１ｂが挿通する開口部である挿通孔１２０と、ベース部１１０から上方及び下方に突出し挿通孔１２０を囲むように形成される円筒状の筒部１１２と、有底円筒形状のハブ１１３と、を備える。 FIG. 2 is a perspective view of the spring guide 100. As shown in FIGS. 1 and 2, the spring guide 100 is a resin-made dish-shaped member fixed to the outer periphery of the cylinder 1b. The spring guide 100 includes a disk-shaped base portion 110 that supports the coil spring 4, a side wall 111 that extends from the outer edge of the base portion 110 to the upper side (upper mount 2 side), and the base portion 110 that serves as an axis of the suspension device 10. Is formed so as to pass through in the direction (vertical direction) and is an opening through which the cylinder 1b of the shock absorber 1 is inserted, and an insertion hole 120 that projects upward and downward from the base 110 and surrounds the insertion hole 120. A cylindrical tubular portion 112 and a bottomed cylindrical hub 113 are provided.
　ベース部１１０におけるハブ１１３の周囲は、ラバーシート４０が取り付けられる取付領域とされる。ベース部１１０には、ラバーシート４０の位置を規制する位置規制部（不図示）が設けられる。ラバーシート４０は、ゴムなどの弾性を有する材料によって形成される。ラバーシート４０には、その断面がコイルスプリング４の断面形状に沿うように湾曲して形成される着座部４０ａ（図１参照）が設けられる。スプリングガイド１００には、軽量化、及びベース部１１０に溜まった水を抜くために複数の貫通孔（不図示）が形成される。 The periphery of the hub 113 in the base 110 is an attachment area to which the rubber sheet 40 is attached. The base portion 110 is provided with a position regulating portion (not shown) that regulates the position of the rubber sheet 40. The rubber sheet 40 is formed of a material having elasticity such as rubber. The rubber sheet 40 is provided with a seating portion 40a (see FIG. 1) which is curved so that its cross section follows the cross sectional shape of the coil spring 4. The spring guide 100 is formed with a plurality of through holes (not shown) to reduce the weight and drain water accumulated in the base 110.
　ベース部１１０から軸方向に突出する筒部１１２は、その内周が円形状の挿通孔１２０とされている。図１に示すように、挿通孔１２０は、スプリングガイド１００をシリンダ１ｂの外周に固定したときに、スプリングガイド１００の中心から車体側に偏心した位置になるように形成される。 The cylindrical portion 112 protruding in the axial direction from the base portion 110 has a circular insertion hole 120 on the inner periphery thereof. As shown in FIG. 1, when the spring guide 100 is fixed to the outer circumference of the cylinder 1b, the insertion hole 120 is formed at a position eccentric to the vehicle body side from the center of the spring guide 100.
　シリンダ１ｂの外周には、金属製の支持リング３が溶接により固定されている。スプリングガイド１００は、挿通孔１２０がシリンダ１ｂの外周に嵌合され、スプリングガイド１００の筒部１１２の下端部が支持リング３によって支持されることで、シリンダ１ｂの外周に固定される。 A metal support ring 3 is fixed to the outer periphery of the cylinder 1b by welding. The spring guide 100 is fixed to the outer periphery of the cylinder 1b by inserting the insertion hole 120 into the outer periphery of the cylinder 1b and supporting the lower end of the cylindrical portion 112 of the spring guide 100 by the support ring 3.
　なお、シリンダ１ｂと挿通孔１２０のはめあい、具体的にはシリンダ１ｂと挿通孔１２０に形成されるリブ１２２（図２参照）とのはめあいは、「すきまばめ」であってもよいし、「しまりばめ」であってもよい。「しまりばめ」を採用する場合、挿通孔１２０とシリンダ１ｂとの間のガタがなくなり、ガタによる異音の発生を防止することができる。また、サスペンション装置１０の動作の応答性を向上することもできる。 The fit between the cylinder 1b and the insertion hole 120, specifically, the fit between the cylinder 1b and the rib 122 (see FIG. 2) formed in the insert hole 120 may be a "clearance fit" or "a clearance fit". It may be a "shrink fit". When the "tight fit" is adopted, there is no play between the insertion hole 120 and the cylinder 1b, and it is possible to prevent the generation of noise due to the play. Further, the responsiveness of the operation of the suspension device 10 can be improved.
　スプリングガイド１００は、上方からシリンダ１ｂに嵌め込まれ、支持リング３に当接することで、シリンダ１ｂに取り付けられる。換言すれば、シリンダ１ｂは、スプリングガイド１００の挿通孔１２０の下部開口端１２５Ｌから挿入される。つまり、下部開口端１２５Ｌは、シリンダ１ｂが挿入される入口であり、下部開口端１２５Ｌの反対側の開口端である上部開口端１２５Ｕからシリンダ１ｂの上端部が突出する。 The spring guide 100 is attached to the cylinder 1b by being fitted into the cylinder 1b from above and coming into contact with the support ring 3. In other words, the cylinder 1b is inserted from the lower opening end 125L of the insertion hole 120 of the spring guide 100. That is, the lower opening end 125L is an inlet into which the cylinder 1b is inserted, and the upper end of the cylinder 1b projects from the upper opening end 125U, which is the opening end opposite to the lower opening end 125L.
　図２に示すように、挿通孔１２０には、その内周面１２１から径方向内側に向かって突出する凸部としてのリブ１２２が設けられる。リブ１２２は、ショックアブソーバ１のシリンダ１ｂの外周面を支持する支持部として機能する。各リブ１２２は、挿通孔１２０の軸方向（すなわち、サスペンション装置１０の軸方向）に沿って直線状に設けられる。 As shown in FIG. 2, the insertion hole 120 is provided with a rib 122 as a convex portion that protrudes radially inward from the inner peripheral surface 121 thereof. The rib 122 functions as a support portion that supports the outer peripheral surface of the cylinder 1b of the shock absorber 1. Each rib 122 is provided linearly along the axial direction of the insertion hole 120 (that is, the axial direction of the suspension device 10).
　リブ１２２は、例えば、その断面形状が丸みを帯びた台形状あるいは半円形状となるように形成され、シリンダ１ｂの外周面に線接触する。リブ１２２は、挿通孔１２０の周方向に沿って等間隔で複数配置される。このため、スプリングガイド１００は、挿通孔１２０の中心軸がシリンダ１ｂの中心軸に一致するように位置決めされる。 The rib 122 is formed, for example, so that its cross-sectional shape is a rounded trapezoidal shape or a semicircular shape, and is in line contact with the outer peripheral surface of the cylinder 1b. A plurality of ribs 122 are arranged at equal intervals along the circumferential direction of the insertion hole 120. Therefore, the spring guide 100 is positioned such that the central axis of the insertion hole 120 matches the central axis of the cylinder 1b.
　バンプストッパ５は、弾性を有するゴム、樹脂等の弾性材によって形成される。バンプストッパ５は、ロッド１ａに取り付けられ、ショックアブソーバ１が所定量だけ収縮したときにバンプキャップ１６０に当たることによりショックアブソーバ１の縮み側のストロークを規制する。ショックアブソーバ１の最収縮時には、バンプストッパ５がバンプキャップ１６０に接触して弾性変形するため、最収縮時の衝撃が緩和される。 The bump stopper 5 is formed of an elastic material such as rubber or resin having elasticity. The bump stopper 5 is attached to the rod 1a, and hits the bump cap 160 when the shock absorber 1 contracts by a predetermined amount to restrict the stroke of the shock absorber 1 on the contracting side. When the shock absorber 1 is in the most contracted state, the bump stopper 5 comes into contact with the bump cap 160 and elastically deforms.
　図３は、スプリングガイド１００とバンプキャップ１６０との当接部を拡大して示す拡大断面模式図である。図１及び図３に示すように、バンプキャップ１６０は、アウターチューブ１１ｏの開口部１４２を覆うように、シリンダ１ｂのロッド１ａ側の端部（上端部）に取り付けられる。バンプキャップ１６０は、樹脂により形成される。 FIG. 3 is an enlarged schematic sectional view showing an enlarged contact portion between the spring guide 100 and the bump cap 160. As shown in FIGS. 1 and 3, the bump cap 160 is attached to the end (upper end) of the cylinder 1b on the rod 1a side so as to cover the opening 142 of the outer tube 11o. The bump cap 160 is made of resin.
　なお、本実施形態では、バンプキャップ１６０は、スプリングガイド１００よりも柔軟性を有する材料により形成される。バンプキャップ１６０の材料の弾性率（ヤング率）は、スプリングガイド１００の材料の弾性率（ヤング率）よりも低い。 In the present embodiment, the bump cap 160 is made of a material that is more flexible than the spring guide 100. The elastic modulus (Young's modulus) of the material of the bump cap 160 is lower than the elastic modulus (Young's modulus) of the material of the spring guide 100.
　バンプキャップ１６０は、円筒状の嵌合部１６１と、嵌合部１６１の上端部から径方向内側に向かって延在する円環状の環状部１６４と、を有する。 The bump cap 160 has a cylindrical fitting portion 161, and an annular ring-shaped portion 164 extending from the upper end of the fitting portion 161 toward the inside in the radial direction.
　シリンダ１ｂの上端部は、嵌合部１６１の内周に圧入される。バンプキャップ１６０は、嵌合部１６１の下端部がスプリングガイド１００の筒部１１２の上端部に当接した状態で、シリンダ１ｂの上端部に取り付けられる。 The upper end of the cylinder 1b is press fitted into the inner circumference of the fitting part 161. The bump cap 160 is attached to the upper end of the cylinder 1b in a state where the lower end of the fitting portion 161 is in contact with the upper end of the tubular portion 112 of the spring guide 100.
　このため、スプリングガイド１００は、支持リング３（図１参照）とバンプキャップ１６０とによって軸方向に挟持される。つまり、嵌合部１６１は、スプリングガイド１００の筒部１１２の上端部に当接し、シリンダ１ｂに対するスプリングガイド１００の軸方向の移動を規制する規制部として機能する。 Therefore, the spring guide 100 is axially sandwiched by the support ring 3 (see FIG. 1) and the bump cap 160. That is, the fitting portion 161 contacts the upper end portion of the cylindrical portion 112 of the spring guide 100, and functions as a regulating portion that regulates the axial movement of the spring guide 100 with respect to the cylinder 1b.
　図４に示すように、サスペンション装置１０を組み立てる工程において、ショックアブソーバ１のシリンダ１ｂにスプリングガイド１００を嵌合させた状態の中間組立体９０を吊り具９１により吊り上げ、所定の場所まで運搬することがある。中間組立体９０には、コイルスプリング４、アッパーマウント２、バンプストッパ５等が取り付けられていない。 As shown in FIG. 4, in the process of assembling the suspension device 10, the intermediate assembly 90 in which the spring guide 100 is fitted to the cylinder 1b of the shock absorber 1 is lifted by the lifting tool 91 and transported to a predetermined place. There is. The coil spring 4, the upper mount 2, the bump stopper 5 and the like are not attached to the intermediate assembly 90.
　吊り具９１は、スプリングガイド１００のベース部１１０を下方から持ち上げるように支持し、中間組立体９０を吊り上げる。本実施形態では、スプリングガイド１００の筒部１１２の上端部が、バンプキャップ１６０の嵌合部１６１の下端部に当接している。このため、吊り具９１からスプリングガイド１００に上向きの外力が作用した場合であっても、スプリングガイド１００がシリンダ１ｂから外れてしまうことを防止することができる。 The hoisting tool 91 supports the base portion 110 of the spring guide 100 so as to be lifted from below, and hoists the intermediate assembly 90. In the present embodiment, the upper end of the cylindrical portion 112 of the spring guide 100 is in contact with the lower end of the fitting portion 161 of the bump cap 160. Therefore, even when an upward external force is applied to the spring guide 100 from the suspending tool 91, the spring guide 100 can be prevented from coming off the cylinder 1b.
　車両は様々な環境で使用される。例えば、降雪の多い地域において車両が走行する場合、サスペンション装置１０は、融雪剤を含んだ水と接触することがある。融雪剤は塩化カルシウムを含んでいる。このため、シリンダ１ｂの外周と挿通孔１２０の内周との間に塩化カルシウムを含んだ水が侵入してしまうと、挿通孔１２０の内周が劣化し、損傷してしまうおそれがある。 Vehicles are used in various environments. For example, when the vehicle runs in an area with a lot of snow, the suspension device 10 may come into contact with water containing a snow melting agent. The snow melting agent contains calcium chloride. Therefore, if water containing calcium chloride enters between the outer periphery of the cylinder 1b and the inner periphery of the insertion hole 120, the inner periphery of the insertion hole 120 may be deteriorated and damaged.
　本実施形態では、図３に示すように、バンプキャップ１６０の嵌合部１６１の下端面が、挿通孔１２０の上部開口縁部（筒部１１２の端面）の全周に亘って当接している。バンプキャップ１６０は、スプリングガイド１００の挿通孔１２０の上部開口縁部に密着し、シリンダ１ｂの外周と挿通孔１２０との間の隙間を閉塞する。 In the present embodiment, as shown in FIG. 3, the lower end surface of the fitting portion 161 of the bump cap 160 is in contact with the entire circumference of the upper opening edge portion of the insertion hole 120 (the end surface of the tubular portion 112). .. The bump cap 160 is in close contact with the upper opening edge of the insertion hole 120 of the spring guide 100 and closes the gap between the outer periphery of the cylinder 1b and the insertion hole 120.
　このため、バンプキャップ１６０によって、シリンダ１ｂと挿通孔１２０との間の隙間に、砂、水等の異物が侵入することを防止することができる。したがって、シリンダ１ｂの外周と挿通孔１２０の内周との間の隙間に異物が侵入することに起因した劣化、損傷を防止することができる。 Therefore, the bump cap 160 can prevent foreign matter such as sand and water from entering the gap between the cylinder 1b and the insertion hole 120. Therefore, it is possible to prevent deterioration and damage due to foreign matter entering the gap between the outer circumference of the cylinder 1b and the inner circumference of the insertion hole 120.
　上述した実施形態によれば、次の作用効果を奏する。 According to the above-described embodiment, the following operational effects are achieved.
　（１）バンプキャップ１６０の嵌合部１６１の下端部が、スプリングガイド１００の筒部１１２の上端部に当接することにより、シリンダ１ｂに対するスプリングガイド１００の軸方向の移動が規制される。この構成によれば、サスペンション装置１０の組み立て作業において、シリンダ１ｂの上端部に取り付けられるバンプキャップ１６０によって、スプリングガイド１００の軸方向の移動を規制することができる。 (1) The lower end of the fitting portion 161 of the bump cap 160 comes into contact with the upper end of the tubular portion 112 of the spring guide 100, thereby restricting the axial movement of the spring guide 100 with respect to the cylinder 1b. According to this configuration, in the assembly work of the suspension device 10, the movement of the spring guide 100 in the axial direction can be restricted by the bump cap 160 attached to the upper end of the cylinder 1b.
　このため、バンプキャップ１６０とは別に、スプリングガイド１００の移動を規制する部材を設ける必要がない。つまり、部品点数を増加させることなく、スプリングガイド１００に外力が作用したときに、スプリングガイド１００がショックアブソーバ１から外れてしまうことを防止することができる。サスペンション装置１０の組み立て作業において、スプリングガイド１００がショックアブソーバ１から外れてしまうことを防止できるので、サスペンション装置１０の組み立て作業の効率を向上することができる。 Therefore, it is not necessary to provide a member for restricting the movement of the spring guide 100 separately from the bump cap 160. That is, it is possible to prevent the spring guide 100 from coming off the shock absorber 1 when an external force acts on the spring guide 100 without increasing the number of parts. Since it is possible to prevent the spring guide 100 from coming off the shock absorber 1 during the assembly work of the suspension device 10, the efficiency of the assembly work of the suspension device 10 can be improved.
　また、サスペンション装置１０の組み立て作業において、吊り具９１によってスプリングガイド１００を支持し、中間組立体９０を吊り上げ、所定の場所まで運搬するという工程を採用することもできるので、サスペンション装置１０の組み立て作業の自由度が高い。 Further, in the assembly work of the suspension device 10, it is possible to employ a process of supporting the spring guide 100 by the suspending tool 91, lifting the intermediate assembly 90, and transporting it to a predetermined place. Has a high degree of freedom.
　（２）本実施形態では、スプリングガイド１００の筒部１１２と、バンプキャップ１６０の筒状の嵌合部１６１とが当接している。このため、スプリングガイド１００に対して、下側から上方に向かう外力が作用したときに、スプリングガイド１００の筒部１１２に作用する荷重を周方向に均等にすることができる。 (2) In this embodiment, the tubular portion 112 of the spring guide 100 and the tubular fitting portion 161 of the bump cap 160 are in contact with each other. Therefore, when an external force is applied to the spring guide 100 from the lower side to the upper side, the load acting on the tubular portion 112 of the spring guide 100 can be made uniform in the circumferential direction.
　このため、スプリングガイド１００とバンプキャップ１６０とを局所的に当接させる場合に比べて、スプリングガイド１００がシリンダ１ｂから外れてしまうことを、効果的に防止することができる。 Therefore, as compared with the case where the spring guide 100 and the bump cap 160 are locally brought into contact with each other, the spring guide 100 can be effectively prevented from coming off the cylinder 1b.
　次のような変形例も本発明の範囲内であり、変形例に示す構成と上述の実施形態で説明した構成を組み合わせたり、以下の異なる変形例で説明する構成同士を組み合わせたりすることも可能である。 The following modified examples are also within the scope of the present invention, and it is possible to combine the configurations described in the modified examples with the configurations described in the above-described embodiments or to combine the configurations described in the following different modified examples. Is.
　＜変形例１＞
　上記実施形態では、バンプキャップ１６０が、スプリングガイド１００の軸方向の移動のみを規制する例について説明したが、本発明はこれに限定されない。以下で説明するように、バンプキャップ２６０，３６０が、スプリングガイド２００，３００の径方向の移動を規制するようにしてもよい。 <Modification 1>
Although the bump cap 160 regulates only the axial movement of the spring guide 100 in the above embodiment, the present invention is not limited to this. As described below, the bump caps 260 and 360 may restrict the radial movement of the spring guides 200 and 300.
　＜変形例１－１＞
　図５Ａに示すように、バンプキャップ２６０の嵌合部２６１の下端面２６１ａ、及び、スプリングガイド２００の筒部２１２の上端面２１２ａは、サスペンション装置１０の軸方向に直交する平面に対して傾斜する傾斜面としてもよい。 <Modification 1-1>
As shown in FIG. 5A, the lower end surface 261a of the fitting portion 261 of the bump cap 260 and the upper end surface 212a of the tubular portion 212 of the spring guide 200 are inclined with respect to a plane orthogonal to the axial direction of the suspension device 10. It may be an inclined surface.
　本変形例では、嵌合部２６１の下端面２６１ａが、嵌合部２６１の内径が下方に向かって徐々に大きくなるように、傾斜している。また、筒部２１２の上端面２１２ａが、筒部２１２の外径が上方に向かって徐々に小さくなるように傾斜している。つまり、互いに当接する嵌合部２６１及び筒部２１２の傾斜面は、下方に向かって径方向外側に傾斜している。 In this modification, the lower end surface 261a of the fitting portion 261 is inclined so that the inner diameter of the fitting portion 261 gradually increases downward. In addition, the upper end surface 212a of the tubular portion 212 is inclined so that the outer diameter of the tubular portion 212 gradually decreases upward. That is, the inclined surfaces of the fitting portion 261 and the cylindrical portion 212 that are in contact with each other are inclined downward in the radial direction.
　嵌合部２６１の下端面２６１ａと筒部２１２の上端面２１２ａとは、軸方向に直交する平面に対する傾斜角度が同じであり、下端面２６１ａと上端面２１２ａとは面接触している。 The lower end surface 261a of the fitting portion 261 and the upper end surface 212a of the tubular portion 212 have the same inclination angle with respect to the plane orthogonal to the axial direction, and the lower end surface 261a and the upper end surface 212a are in surface contact with each other.
　つまり、本変形例では、バンプキャップ２６０の嵌合部２６１におけるスプリングガイド２００に当接する面である下端面２６１ａ、及び、スプリングガイド２００の筒部２１２における嵌合部２６１に当接する面である上端面２１２ａの双方が、軸方向に直交する平面に対して傾斜する傾斜面とされている。したがって、本変形例では、バンプキャップ２６０によって、スプリングガイド２００の軸方向及び径方向の移動が規制される。 That is, in the present modification, the lower end surface 261 a of the fitting portion 261 of the bump cap 260 that contacts the spring guide 200, and the surface of the tubular portion 212 of the spring guide 200 that contacts the fitting portion 261. Both of the end faces 212a are inclined faces that are inclined with respect to a plane orthogonal to the axial direction. Therefore, in the present modification, the bump cap 260 restricts the movement of the spring guide 200 in the axial direction and the radial direction.
　スプリングガイド２００は、シリンダ１ｂに嵌合され、支持リング３上に載置される。その後、バンプキャップ２６０をシリンダ１ｂの上端部に圧入する。このとき、嵌合部２６１の下端面２６１ａと筒部２１２の上端面２１２ａとが接触することにより、スプリングガイド２００の挿通孔１２０の中心軸がシリンダ１ｂの中心軸に一致するように、スプリングガイド２００が移動し、適切な位置決めがなされる。つまり、本変形例によれば、シリンダ１ｂに対するスプリングガイド２００の位置決め精度を向上することができる。 The spring guide 200 is fitted into the cylinder 1b and placed on the support ring 3. Then, the bump cap 260 is pressed into the upper end of the cylinder 1b. At this time, the lower end surface 261a of the fitting portion 261 and the upper end surface 212a of the tubular portion 212 contact each other, so that the central axis of the insertion hole 120 of the spring guide 200 matches the central axis of the cylinder 1b. 200 moves and is properly positioned. That is, according to this modification, the positioning accuracy of the spring guide 200 with respect to the cylinder 1b can be improved.
　本変形例では、バンプキャップ２６０をシリンダ１ｂの上端部に装着することにより、スプリングガイド２００の筒部２１２が精度良くセンタリングされる。このため、コイルスプリング４を介して上方からスプリングガイド１００に荷重が作用したときに、スプリングガイド２００の筒部２１２に偏荷重が作用することを防止することができる。 In this modification, by mounting the bump cap 260 on the upper end of the cylinder 1b, the cylindrical portion 212 of the spring guide 200 is accurately centered. Therefore, when a load acts on the spring guide 100 from above via the coil spring 4, it is possible to prevent an unbalanced load from acting on the cylindrical portion 212 of the spring guide 200.
　また、本変形例では、バンプキャップ２６０の嵌合部２６１によってスプリングガイド２００の径方向の移動が規制されるので、スプリングガイド２００の径方向の移動を規制するための専用の部材を設ける必要がない。 Further, in this modification, since the fitting portion 261 of the bump cap 260 restricts the radial movement of the spring guide 200, it is necessary to provide a dedicated member for restricting the radial movement of the spring guide 200. Absent.
　＜変形例１－２＞
　上記変形例１－１では、嵌合部２６１及び筒部２１２の傾斜面が、下方に向かって径方向外側に傾斜する例について説明したが、図５Ｂに示すように、下方に向かって径方向内側に傾斜するようにしてもよい。このような構成であっても、バンプキャップ２６０をシリンダ１ｂの上端部に装着することにより、シリンダ１ｂに対し、スプリングガイド２００を精度良く位置決めすることができる。 <Modification 1-2>
In the above-described modification 1-1, an example in which the inclined surfaces of the fitting portion 261 and the cylindrical portion 212 are inclined downward in the radial direction is described, but as shown in FIG. 5B, the radial direction is reduced in the downward direction. It may be inclined inward. Even with such a configuration, by mounting the bump cap 260 on the upper end portion of the cylinder 1b, the spring guide 200 can be accurately positioned with respect to the cylinder 1b.
　＜変形例１－３＞
　上記変形例１－１及び変形例１－２では、嵌合部２６１及び筒部２１２の双方に、傾斜面が設けられる例について説明したが、嵌合部２６１及び筒部２１２の少なくとも一方に、傾斜面を設けることもできる。 <Modification 1-3>
In the modified example 1-1 and the modified example 1-2, the example in which the inclined surfaces are provided on both the fitting portion 261 and the tubular portion 212 has been described, but at least one of the fitting portion 261 and the tubular portion 212 is It is also possible to provide an inclined surface.
　図６Ａに示すように、本変形例では、バンプキャップ２６０の嵌合部２６１の下端面２６１ａは傾斜面であるのに対し、スプリングガイド３００の筒部３１２の上端面３１２ａは、上側に凸の湾曲面とされる。 As shown in FIG. 6A, in the present modification, the lower end surface 261a of the fitting portion 261 of the bump cap 260 is an inclined surface, while the upper end surface 312a of the tubular portion 312 of the spring guide 300 is convex upward. It is a curved surface.
　＜変形例１－４＞
　図６Ｂに示すように、本変形例では、スプリングガイド２００の筒部２１２の上端面２１２ａは傾斜面であるのに対し、バンプキャップ３６０の嵌合部３６１の下端面３６１ａは、下側に凸の湾曲面とされる。 <Modification 1-4>
As shown in FIG. 6B, in this modified example, the upper end surface 212a of the tubular portion 212 of the spring guide 200 is an inclined surface, while the lower end surface 361a of the fitting portion 361 of the bump cap 360 is convex downward. Is a curved surface.
　変形例１－３及び変形例１－４では、嵌合部２６１及び筒部２１２の少なくとも一方に、傾斜面を設けることにより、上記変形例１－１及び変形例１－２と同様の作用効果を得ることができる。なお、上記変形例１－１及び変形例１－２では、筒部２１２と嵌合部２６１とが面接触するため、変形例１－３及び変形例１－４に比べて、シリンダ１ｂの外周と挿通孔１２０の内周との間の隙間に異物が侵入することを、より効果的に防止することができる。 In the modified example 1-3 and the modified example 1-4, by providing an inclined surface on at least one of the fitting part 261 and the cylindrical part 212, the same effect as the modified example 1-1 and the modified example 1-2 can be obtained. Can be obtained. In the modified example 1-1 and the modified example 1-2, since the cylindrical portion 212 and the fitting portion 261 are in surface contact with each other, the outer circumference of the cylinder 1b is different from that of the modified example 1-3 and the modified example 1-4. It is possible to more effectively prevent foreign matter from entering the gap between the inner periphery of the insertion hole 120 and the inner periphery of the insertion hole 120.
