Description

スタビライザブラケットStabilizer bracket
　本発明は、スタビライザブラケットの改良に関する。 The present invention relates to an improvement of a stabilizer bracket.
　一般に、自動車の左右の前輪と車体との間には、それぞれ緩衝器が介装されている。緩衝器は、路面の凹凸による衝撃が車体に伝わることを抑制する。左右の前輪の各緩衝器は、スタビライザで連結されている。スタビライザは、左右の前輪が逆位相に動くときに捩られて所定の反力を発生するスタビライザバーと、スタビライザバーの両端と各緩衝器との間に介装される左右のスタビライザリンクと、を備える。スタビライザは、車体のロールを抑制して車体の姿勢を安定させる。各緩衝器には、スタビライザブラケットが取り付けられる。スタビライザブラケットは、緩衝器とスタビライザリンクとを連結する。 Generally, a shock absorber is interposed between the left and right front wheels of the automobile and the vehicle body. The shock absorber suppresses an impact caused by road surface unevenness from being transmitted to the vehicle body. The shock absorbers on the left and right front wheels are connected by a stabilizer. The stabilizer includes a stabilizer bar that is twisted when the left and right front wheels move in opposite phases and generates a predetermined reaction force, and left and right stabilizer links interposed between both ends of the stabilizer bar and each shock absorber. Prepare. The stabilizer suppresses the roll of the vehicle body and stabilizes the posture of the vehicle body. A stabilizer bracket is attached to each shock absorber. The stabilizer bracket connects the shock absorber and the stabilizer link.
　ＪＰ１０－１１９５２７Ａには、緩衝器の外筒の外周面に溶接固定される連結部と、連結部の一方側端部に沿って起立して外筒の軸方向に沿って配置される板状の取り付け部と、を備えるスタビライザブラケットが開示されている。このスタビライザブラケットでは、取り付け部の略中央にスタビライザ取り付け用の孔が形成される。取り付け用の孔には、スタビライザリンクの上端部が連結される。スタビライザバーの一方側端部は、スタビライザリンクの下端部に連結される。 JP10-119527A includes a connecting portion that is welded and fixed to the outer peripheral surface of the outer cylinder of the shock absorber, and a plate-like shape that rises along one end of the connecting portion and is arranged along the axial direction of the outer cylinder. A stabilizer bracket comprising an attachment portion is disclosed. In this stabilizer bracket, a hole for attaching the stabilizer is formed in the approximate center of the attachment portion. The upper end of the stabilizer link is connected to the mounting hole. One end of the stabilizer bar is connected to the lower end of the stabilizer link.
　ＪＰ１０－１１９５２７Ａの緩衝器の外筒には、懸架ばねの下端を支持するスプリングシートと、車輪を支持するナックルに緩衝器を連結するためのナックルブラケットと、が取り付けられる。スタビライザブラケットは、スプリングシートとナックルブラケットとの間に配置される。このような緩衝器では、スプリングシートとナックルブラケットとが接近する等の理由により、緩衝器の外筒にスタビライザブラケットの連結部を溶接するための充分なスペースを確保することが困難な場合がある。 The outer cylinder of the shock absorber of JP10-119527A is attached with a spring seat that supports the lower end of the suspension spring and a knuckle bracket that connects the shock absorber to the knuckle that supports the wheel. The stabilizer bracket is disposed between the spring seat and the knuckle bracket. In such a shock absorber, it may be difficult to secure a sufficient space for welding the connecting portion of the stabilizer bracket to the outer cylinder of the shock absorber, for example, because the spring seat and the knuckle bracket come close to each other. .
　そのため、スタビライザブラケットの連結部をナックルブラケットに溶接固定する場合がある。この場合、スタビライザ取り付け用の孔の位置をナックルブラケットよりも上側に位置させるために、取り付け部をナックルブラケットの上側に延ばし、この延設部分にスタビライザ取り付け用の孔が形成される。 Therefore, the connecting part of the stabilizer bracket may be welded to the knuckle bracket. In this case, in order to position the stabilizer attachment hole above the knuckle bracket, the attachment portion is extended above the knuckle bracket, and the stabilizer attachment hole is formed in the extended portion.
　しかしながら、延設部分にスタビライザ取り付け用の孔が形成される場合には、スタビライザ取り付け用の孔が連結部の溶接固定区間から軸方向に外れた範囲にある。そのため、延設部分に大きな力が作用するおそれがある。 However, when a hole for attaching the stabilizer is formed in the extended portion, the hole for attaching the stabilizer is in a range deviated in the axial direction from the weld fixing section of the connecting portion. For this reason, a large force may act on the extended portion.
　本発明は、上記の問題点に鑑みてなされたものであり、スタビライザ取り付け用の孔が連結部の固定区間から軸方向に外れている場合にも、孔が形成される部分の強度を確保することを目的とする。 The present invention has been made in view of the above problems, and ensures the strength of the portion where the hole is formed even when the hole for attaching the stabilizer is axially disengaged from the fixed section of the connecting portion.

　以下、図面を参照して、本発明の実施の形態に係るスタビライザブラケットＡについて説明する。複数の図面に付された同一の符号は、同一の部品か又は対応する部品を示す。 Hereinafter, a stabilizer bracket A according to an embodiment of the present invention will be described with reference to the drawings. The same reference numerals in the drawings denote the same or corresponding parts.
　まず、スタビライザブラケットＡの理解を容易にするために、図４及び図５を参照して、本発明の第一の比較例に係るスタビライザブラケットＡ１，及び第二の比較例に係るスタビライザブラケットＡ２について説明する。 First, in order to facilitate understanding of the stabilizer bracket A, referring to FIGS. 4 and 5, the stabilizer bracket A1 according to the first comparative example of the present invention and the stabilizer bracket A2 according to the second comparative example. explain.
　図４に示すように、スタビライザブラケットＡ１は、緩衝器の外筒Ｔの外周面に四隅を溶接固定される矩形板状の連結部１００と、連結部１００の一方側端部に沿って起立して外筒Ｔの軸方向（図４では上下方向）に沿って配置される板状の取り付け部２００と、を備える。取り付け部２００の略中央には、スタビライザ取り付け用の孔２２が形成される。孔２２には、図示しないが、スタビライザリンクの上端部が連結される。また、スタビライザリンクの下端部には、スタビライザバーの一方側端部が連結される。 As shown in FIG. 4, the stabilizer bracket A <b> 1 stands along a rectangular plate-like connecting portion 100 whose four corners are welded and fixed to the outer peripheral surface of the outer cylinder T of the shock absorber, and one end portion of the connecting portion 100. And a plate-like mounting portion 200 disposed along the axial direction of the outer cylinder T (vertical direction in FIG. 4). A stabilizer mounting hole 22 is formed substantially at the center of the mounting portion 200. Although not shown, the upper end portion of the stabilizer link is connected to the hole 22. Also, one end of the stabilizer bar is connected to the lower end of the stabilizer link.
　緩衝器の外筒Ｔには、車体を弾性支持する懸架ばねの下端を支持するスプリングシートＳと、車輪を支持するナックルに緩衝器を連結するためのナックルブラケットＮと、が取り付けられる。スタビライザブラケットＡ１は、スプリングシートＳとナックルブラケットＮとの間に配置される。このような緩衝器においては、スプリングシートＳとナックルブラケットＮとが接近する等の理由により、緩衝器の外筒ＴにスタビライザブラケットＡ１の連結部１００を溶接するための充分なスペースを確保することが困難な場合がある。そのため、連結部１００を外筒ＴとナックルブラケットＮとの両方に溶接する場合がある。 The outer cylinder T of the shock absorber is attached with a spring seat S that supports the lower end of the suspension spring that elastically supports the vehicle body, and a knuckle bracket N for connecting the shock absorber to the knuckle that supports the wheel. The stabilizer bracket A1 is disposed between the spring seat S and the knuckle bracket N. In such a shock absorber, a sufficient space for welding the connecting portion 100 of the stabilizer bracket A1 to the outer cylinder T of the shock absorber is ensured because the spring seat S and the knuckle bracket N are close to each other. May be difficult. Therefore, the connection part 100 may be welded to both the outer cylinder T and the knuckle bracket N.
　しかしながら、連結部１００を外筒ＴとナックルブラケットＮとの両方に溶接すると、緩衝器に力がかかったときに、外筒ＴとナックルブラケットＮが異なる変形をする。そのため、連結部１００の溶接強度が低下するおそれがある。 However, if the connecting portion 100 is welded to both the outer cylinder T and the knuckle bracket N, the outer cylinder T and the knuckle bracket N are deformed differently when a force is applied to the shock absorber. Therefore, there is a possibility that the welding strength of the connecting part 100 is reduced.
　図５に示すように、スタビライザブラケットＡ２は、ナックルブラケットＮに溶接固定される連結部１００と、ナックルブラケットＮの上側に延設されて、この延設部分２０１にスタビライザ取り付け用の孔２２を有する取り付け部２００と、を備える。 As shown in FIG. 5, the stabilizer bracket A <b> 2 is connected to the knuckle bracket N by a welding portion 100, and extends to the upper side of the knuckle bracket N. An attachment unit 200.
　しかしながら、スタビライザブラケットＡ２では、連結部１００の溶接区間（溶接上端から溶接下端までの区間）Ｙからスタビライザ取り付け用の孔２２が軸方向に外れた範囲にある。そのため、延設部分２０１に大きな力が作用するおそれがある。 However, in the stabilizer bracket A2, the stabilizer mounting hole 22 is in the range in which the stabilizer mounting hole 22 deviates in the axial direction from the welding section (section from the upper end of welding to the lower end of welding) Y of the connecting portion 100. For this reason, a large force may act on the extended portion 201.
　次に、図１から図３を参照して、スタビライザブラケットＡの構成について説明する。 Next, the structure of the stabilizer bracket A will be described with reference to FIGS.
　図１に示すように、本実施の形態に係るスタビライザブラケットＡは、緩衝器の外筒Ｔに取り付けられるナックルブラケット（筒状体）Ｎの外周面に溶接固定される連結部１と、この連結部１に連なりスタビライザ取り付け用の孔２２が形成される取り付け部２と、を備える。 As shown in FIG. 1, a stabilizer bracket A according to the present embodiment includes a connecting portion 1 welded and fixed to an outer peripheral surface of a knuckle bracket (tubular body) N attached to an outer tube T of a shock absorber, and this connection. And an attachment portion 2 which is connected to the portion 1 and has a hole 22 for attaching a stabilizer.
　連結部１は、ナックルブラケットＮの外周面に起立した状態で溶接されてナックルブラケットＮの軸方向に沿って配置される軸方向連結片１０を備える。取り付け部２は、軸方向連結片１０からナックルブラケットＮの軸方向上側（一方側）に延びる延設片２０と、この延設片２０の反緩衝器側端部から傾斜して延びる取り付け片２１とを備える。孔２２は、取り付け片２１に形成される。 The connecting portion 1 includes an axial connecting piece 10 which is welded in a standing state on the outer peripheral surface of the knuckle bracket N and arranged along the axial direction of the knuckle bracket N. The attachment portion 2 includes an extension piece 20 that extends from the axial connection piece 10 to the upper side (one side) in the axial direction of the knuckle bracket N, and an attachment piece 21 that extends at an angle from the end of the extension piece 20 opposite to the shock absorber. With. The hole 22 is formed in the attachment piece 21.
　以下、詳細に説明する。緩衝器は、ストラット式サスペンション用の緩衝器である。そして、緩衝器のピストンロッドＲは、アッパーマウント（図示省略）を介して車体に連結される。緩衝器の外筒Ｔは、この外筒Ｔに取り付けられるナックルブラケットＮを介して車輪を支持するナックル（図示省略）に連結される。また、緩衝器の外筒Ｔには、緩衝器を伸長方向に付勢して車体を弾性支持する懸架ばね（図示省略）の下端を支持するスプリングシートＳが取り付けられる。 The details will be described below. The shock absorber is a shock absorber for a strut suspension. The piston rod R of the shock absorber is connected to the vehicle body via an upper mount (not shown). The outer cylinder T of the shock absorber is connected to a knuckle (not shown) that supports the wheel via a knuckle bracket N attached to the outer cylinder T. A spring seat S that supports the lower end of a suspension spring (not shown) that elastically supports the vehicle body by urging the shock absorber in the extending direction is attached to the outer cylinder T of the shock absorber.
　スタビライザブラケットＡは、ナックルブラケットＮに取り付けられる。ナックルブラケットＮは、横断面がＣ字状の略環状に形成される筒状の抱持部ｎ１と、抱持部ｎ１の両端から対向して延びる一対の挟持片ｎ２，ｎ３と、を備えた筒状体である。図２Ａから図２Ｃでは、ナックルブラケットＮの形状を簡略化し、二点鎖線で円柱状に示している。なお、スタビライザブラケットＡは、緩衝器の外筒Ｔや、この外筒Ｔに取り付けられる補強用のカラー等、ナックルブラケットＮ以外の筒状体に取り付けられてもよい。 Stabilizer bracket A is attached to the knuckle bracket N. The knuckle bracket N includes a cylindrical holding portion n1 formed in a substantially annular shape with a C-shaped cross section, and a pair of holding pieces n2 and n3 extending opposite from both ends of the holding portion n1. It is a cylindrical body. In FIG. 2A to FIG. 2C, the shape of the knuckle bracket N is simplified and shown in a cylindrical shape with a two-dot chain line. The stabilizer bracket A may be attached to a cylindrical body other than the knuckle bracket N, such as an outer cylinder T of a shock absorber or a reinforcing collar attached to the outer cylinder T.
　スタビライザブラケットＡは、車体のロールを抑制するスタビライザ（図示省略）と緩衝器Ｄとを連結する。図２Ａから図２Ｃに示すように、スタビライザブラケットＡは、ナックルブラケットＮの外周面に溶接固定される連結部１と、連結部１に連なりスタビライザ取り付け用の孔２２が形成される取り付け部２と、を備える。本実施の形態では、スタビライザブラケットＡは、一枚の板材をプレス成型することにより形成されている。 The stabilizer bracket A connects a stabilizer (not shown) for suppressing the roll of the vehicle body and the shock absorber D. As shown in FIGS. 2A to 2C, the stabilizer bracket A includes a connecting portion 1 that is welded and fixed to the outer peripheral surface of the knuckle bracket N, and an attaching portion 2 that is connected to the connecting portion 1 and has a hole 22 for attaching a stabilizer. . In the present embodiment, the stabilizer bracket A is formed by press molding a single plate material.
　連結部１は、図３に示すように、ナックルブラケットＮの外周面に起立した状態で溶接されてナックルブラケットＮの軸方向（図３では上下方向）に沿って配置される軸方向連結片１０と、ナックルブラケットＮの外周面に起立した状態で溶接されてナックルブラケットＮの周方向に沿って配置される周方向連結片１１と、軸方向連結片１０の反緩衝器側端部（図３では奥側端部）から傾斜して延びる支持片１２と、を備える。 As shown in FIG. 3, the connecting portion 1 is welded in a standing state on the outer peripheral surface of the knuckle bracket N and is arranged along the axial direction (vertical direction in FIG. 3) of the knuckle bracket N. And a circumferential connection piece 11 that is welded in a standing state on the outer peripheral surface of the knuckle bracket N and arranged along the circumferential direction of the knuckle bracket N, and the end part on the side opposite to the shock absorber of the axial connection piece 10 (FIG. 3). Then, the support piece 12 which inclines and extends from the back side edge part) is provided.
　軸方向連結片１０は、図２Ｂに示すように、ナックルブラケットＮの外周面に対して垂直に配置される。軸方向連結片１０の緩衝器側端部１０ａ（図３参照）は、ナックルブラケットＮの外周面に、軸方向に連続して当接している。軸方向連結片１０は、ナックルブラケットＮとの当接部に沿ってスタビライザブラケットＡの外側からナックルブラケットＮに連続すみ肉溶接される。この軸方向の溶接部分は、図２Ａに一点鎖線ｙ１で示される。 The axial connection piece 10 is arranged perpendicular to the outer peripheral surface of the knuckle bracket N as shown in FIG. 2B. The shock absorber side end portion 10a (see FIG. 3) of the axial connection piece 10 is in continuous contact with the outer peripheral surface of the knuckle bracket N in the axial direction. The axial connection piece 10 is continuously fillet welded to the knuckle bracket N from the outside of the stabilizer bracket A along the contact portion with the knuckle bracket N. This welded portion in the axial direction is indicated by a one-dot chain line y1 in FIG. 2A.
　周方向連結片１１は、図２Ａ及び図２Ｂに示すように、ナックルブラケットＮの外周面に対して垂直に配置される。周方向連結片１１の緩衝器側端部１１ａ（図３参照）は、ナックルブラケットＮの外周面に、周方向に連続して当接している。周方向連結片１１は、ナックルブラケットＮとの当接部に沿ってスタビライザブラケットＡの内側から連続すみ肉溶接される。この周方向の溶接部分は、図２Ｃに一点鎖線ｙ２で示される。 The circumferential connecting piece 11 is arranged perpendicular to the outer peripheral surface of the knuckle bracket N as shown in FIGS. 2A and 2B. The shock absorber side end portion 11a (see FIG. 3) of the circumferential connecting piece 11 is in continuous contact with the outer peripheral surface of the knuckle bracket N in the circumferential direction. The circumferential connecting piece 11 is continuously fillet welded from the inside of the stabilizer bracket A along the contact portion with the knuckle bracket N. This welded portion in the circumferential direction is indicated by a one-dot chain line y2 in FIG. 2C.
　このように、連結部１の溶接区間（溶接上端から溶接下端までの区間）は、軸方向の溶接部分（一点鎖線ｙ１）の上端から、周方向の溶接部分（一点鎖線ｙ２）の下端までの範囲となる。なお、軸方向連結片１０及び周方向連結片１１のナックルブラケットＮに対する溶接方法は、連続すみ肉溶接に限らず、断続的にすみ肉溶接をしたり、他の溶接方法を採用したりしてもよい。 Thus, the welding section of the connecting portion 1 (the section from the upper end of welding to the lower end of welding) is from the upper end of the welding portion in the axial direction (one-dot chain line y1) to the lower end of the circumferential welding portion (one-dot chain line y2). It becomes a range. In addition, the welding method with respect to the knuckle bracket N of the axial direction connection piece 10 and the circumferential direction connection piece 11 is not restricted to continuous fillet welding, but intermittently fillet welding or other welding methods are adopted. Also good.
　支持片１２は、図３に示すように、軸方向連結片１０と周方向連結片１１とに連なっている。また、軸方向連結片１０と周方向連結片１１とは、反緩衝器側（図３では奥側）で連なっている。このように、軸方向連結片１０と周方向連結片１１と支持片１２とで、三つの平面が一点を共有して交わってできる立体図形である三面角を構成している。 The support piece 12 is connected to the axial direction connection piece 10 and the circumferential direction connection piece 11 as shown in FIG. Moreover, the axial direction connection piece 10 and the circumferential direction connection piece 11 are continued in the anti-cushioner side (back side in FIG. 3). Thus, the axial connection piece 10, the circumferential connection piece 11, and the support piece 12 constitute a trihedral angle that is a three-dimensional figure formed by three planes sharing one point.
　また、軸方向連結片１０の緩衝器側端部１０ａと周方向連結片１１の緩衝器側端部１１ａとの間には、図２Ａから図３に示すように、切欠き１３が形成される。この切欠き１３によって、軸方向の溶接部分（一点鎖線ｙ１）と周方向の溶接部分（一点鎖線ｙ２）とが接続されないようになっている。 Further, as shown in FIGS. 2A to 3, a notch 13 is formed between the shock absorber side end portion 10 a of the axial connection piece 10 and the shock absorber side end portion 11 a of the circumferential connection piece 11. . The notch 13 prevents the axial welded portion (dashed line y1) from being connected to the circumferential welded portion (dashed line y2).
　図３に示すように、連結部１に連なる取り付け部２は、軸方向連結片１０からナックルブラケットＮの軸方向上側に延びる延設片２０と、延設片２０の反緩衝器側端部（図３では奥側端部）から傾斜して延びる取り付け片２１と、を備える。スタビライザ取り付け用の孔２２は、取り付け片２１に形成される。 As shown in FIG. 3, the attachment portion 2 connected to the connection portion 1 includes an extension piece 20 extending from the axial connection piece 10 to the upper side in the axial direction of the knuckle bracket N, and an end portion of the extension piece 20 on the side of the shock absorber ( 3 and an attachment piece 21 extending obliquely from the rear side end portion. A hole 22 for attaching the stabilizer is formed in the attachment piece 21.
　延設片２０は、軸方向連結片１０の上端から内側にやや傾斜している。延設片２０は、スタビライザブラケットＡを外側（図２Ａに示す正面側）から見たときに、延設片２０と軸方向連結片１０とが山折り形状となっている。延設片２０の横幅ｗ１は、下端から上端にかけて徐々に狭くなっている。これにより、延設片２０の緩衝器側端部２０ａ（図３参照）とナックルブラケットＮとの間には、隙間が形成される。よって、溶接が必要な軸方向連結片１０と、溶接が不要な延設片２０との境界を見分けやすい。 The extending piece 20 is slightly inclined inward from the upper end of the axial connecting piece 10. When the extension piece 20 is viewed from the outside (front side shown in FIG. 2A) of the stabilizer bracket A, the extension piece 20 and the axial connection piece 10 are mountain-folded. The lateral width w1 of the extended piece 20 is gradually narrowed from the lower end to the upper end. Thereby, a gap is formed between the shock absorber side end 20a (see FIG. 3) of the extended piece 20 and the knuckle bracket N. Therefore, it is easy to distinguish the boundary between the axial connection piece 10 that requires welding and the extended piece 20 that does not require welding.
　取り付け片２１は、支持片１２からナックルブラケットＮの軸方向上側に延びる。取り付け片２１は、支持片１２の上端から内側にやや傾斜している。取り付け片２１は、スタビライザブラケットＡを外側（図２Ａに示す正面側）から見たときに、取り付け片２１と支持片１２が山折り形状となっている。 The attachment piece 21 extends from the support piece 12 to the upper side in the axial direction of the knuckle bracket N. The attachment piece 21 is slightly inclined inward from the upper end of the support piece 12. The mounting piece 21 has a mountain fold shape when the stabilizer bracket A is viewed from the outside (front side shown in FIG. 2A).
　次に、スタビライザブラケットＡの作用効果について説明する。 Next, the effect of the stabilizer bracket A will be described.
　スタビライザブラケットＡは、緩衝器の外筒Ｔに取り付けられるナックルブラケットＮの外周面に溶接固定される連結部１と、連結部１に連なりスタビライザ取り付け用の孔２２が形成される取り付け部２と、を備える。 The stabilizer bracket A includes a connecting portion 1 that is welded and fixed to an outer peripheral surface of a knuckle bracket N that is attached to the outer cylinder T of the shock absorber, an attachment portion 2 that is connected to the connecting portion 1 and has a hole 22 for attaching a stabilizer, Is provided.
　連結部１は、ナックルブラケットＮの外周面に起立した状態で溶接されてナックルブラケットＮの軸方向に沿って配置される軸方向連結片１０を備える。取り付け部２は、軸方向連結片１０からナックルブラケットＮの軸方向上側（一方側）に延びる延設片２０と、延設片２０の反緩衝器側端部から傾斜して延びる取り付け片２１と、を備える。孔２２は、取り付け片２１に形成される。 The connecting portion 1 includes an axial connecting piece 10 which is welded in a standing state on the outer peripheral surface of the knuckle bracket N and arranged along the axial direction of the knuckle bracket N. The attachment portion 2 includes an extension piece 20 that extends from the axial connection piece 10 to the upper side (one side) in the axial direction of the knuckle bracket N, and an attachment piece 21 that extends at an angle from the end of the extension piece 20 opposite to the shock absorber. . The hole 22 is formed in the attachment piece 21.
　よって、スタビライザ取り付け用の孔２２が、連結部１の溶接区間（溶接上端から溶接下端までの区間）Ｙから軸方向（図１では上下方向）に外れた範囲にあったとしても、孔２２が形成される取り付け片２１を、軸方向連結片１０に連なる延設片２０で補強することができる。したがって、取り付け片２１の強度を確保することができる。 Therefore, even if the hole 22 for attaching the stabilizer is in a range deviated in the axial direction (vertical direction in FIG. 1) from the welding section (the section from the upper end of welding to the lower end of welding) Y of the connecting portion 1, The formed attachment piece 21 can be reinforced by the extended piece 20 that continues to the axial connection piece 10. Therefore, the strength of the attachment piece 21 can be ensured.
　また、連結部１は、ナックルブラケットＮの外周面に起立した状態で溶接されてナックルブラケットＮの周方向に沿って配置される周方向連結片１１を備える。周方向連結片１１は、軸方向連結片１０に連なっている。 Further, the connecting portion 1 includes a circumferential connecting piece 11 which is welded in a standing state on the outer peripheral surface of the knuckle bracket N and arranged along the circumferential direction of the knuckle bracket N. The circumferential connecting piece 11 is continuous with the axial connecting piece 10.
　よって、ナックルブラケットＮとスタビライザブラケットＡとの溶接強度を向上させることが可能である。 Therefore, the welding strength between the knuckle bracket N and the stabilizer bracket A can be improved.
　また、連結部１は、軸方向連結片１０の反緩衝器側端部から傾斜して延びる支持片１２を備える。支持片１２は、取り付け片２１と上記周方向連結片１１とに連なっている。 Further, the connecting portion 1 includes a support piece 12 that extends at an angle from the end on the side opposite to the shock absorber of the axial connecting piece 10. The support piece 12 continues to the attachment piece 21 and the circumferential connecting piece 11.
　よって、支持片１２によっても取り付け片２１を補強することが可能である。したがって、取り付け片２１の強度を更に向上させることができる。 Therefore, the attachment piece 21 can be reinforced also by the support piece 12. Therefore, the strength of the attachment piece 21 can be further improved.
　また、軸方向連結片１０と周方向連結片１１とは連なっている。そして、軸方向連結片１０と周方向連結片１１と上記支持片１２とは三面角を構成している。 Further, the axial connecting piece 10 and the circumferential connecting piece 11 are connected. And the axial direction connection piece 10, the circumferential direction connection piece 11, and the said support piece 12 comprise the trihedral angle.
　よって、連結部１の強度を向上させることが可能である。特に、本実施の形態のように、一枚の板材をプレス成型することによってスタビライザブラケットＡを形成する場合には、軸方向連結片１０と周方向連結片１１と支持片１２とで三面角を構成することで、スタビライザブラケットＡの剛性を向上させることが可能である。 Therefore, it is possible to improve the strength of the connecting portion 1. In particular, when the stabilizer bracket A is formed by press-molding a single plate material as in this embodiment, the axial connection piece 10, the circumferential connection piece 11, and the support piece 12 have a trihedral angle. By configuring, the rigidity of the stabilizer bracket A can be improved.
　また、軸方向連結片１０は、ナックルブラケットＮの外周面に対して垂直に配置される。周方向連結片１１は、ナックルブラケットＮの外周面に対して垂直に配置される。 Further, the axial connection piece 10 is arranged perpendicular to the outer peripheral surface of the knuckle bracket N. The circumferential connecting piece 11 is disposed perpendicular to the outer peripheral surface of the knuckle bracket N.
　よって、軸方向連結片１０とナックルブラケットＮとの溶接や、周方向連結片１１とナックルブラケットＮとの溶接を容易にすることが可能である。 Therefore, welding between the axial connecting piece 10 and the knuckle bracket N and welding between the circumferential connecting piece 11 and the knuckle bracket N can be facilitated.
　また、軸方向連結片１０の緩衝器側端部１０ａは、ナックルブラケットＮの外周面に軸方向に連続して当接する。周方向連結片１１の緩衝器側端部１１ａは、ナックルブラケットＮの外周面に周方向に連続して当接する。 Further, the shock absorber side end portion 10a of the axial connecting piece 10 continuously contacts the outer peripheral surface of the knuckle bracket N in the axial direction. The shock absorber side end portion 11a of the circumferential connecting piece 11 continuously contacts the outer peripheral surface of the knuckle bracket N in the circumferential direction.
　よって、軸方向連結片１０とナックルブラケットＮとは、当接部に沿って溶接され、周方向連結片１１とナックルブラケットＮとは、当接部に沿って溶接されるため、連続すみ肉溶接によって容易に溶接することが可能である。 Therefore, since the axial connection piece 10 and the knuckle bracket N are welded along the contact portion, and the circumferential connection piece 11 and the knuckle bracket N are welded along the contact portion, continuous fillet welding is performed. Can be easily welded.
　また、軸方向連結片１０と延設片２０とは、互いに傾斜して配置される。支持片１２と取り付け片２１ともまた、互いに傾斜して配置される。 Further, the axial connecting piece 10 and the extending piece 20 are arranged to be inclined with respect to each other. The support piece 12 and the attachment piece 21 are also arranged to be inclined with respect to each other.
　よって、スタビライザブラケットＡの強度をより向上させることが可能である。 Therefore, the strength of the stabilizer bracket A can be further improved.
　また、スタビライザブラケットＡは、緩衝器の外筒Ｔに取り付けられるナックルブラケットＮに取り付けられる。そのため、スプリングシートＳとナックルブラケットＮとが接近する等、緩衝器の外筒ＴにスタビライザブラケットＡを取り付けるスペースの確保ができない場合に、特に有効である。 Further, the stabilizer bracket A is attached to the knuckle bracket N attached to the outer cylinder T of the shock absorber. Therefore, this is particularly effective when the space for attaching the stabilizer bracket A to the outer cylinder T of the shock absorber cannot be secured, for example, when the spring seat S and the knuckle bracket N approach each other.
　以上の実施の形態によれば、以下に示す効果を奏する。 According to the above embodiment, the following effects are obtained.
　スタビライザブラケットＡでは、孔２２が形成される取り付け片２１は、軸方向連結片１０に連なる延設片２０で補強される。よって、スタビライザ取り付け用の孔２２が連結部１の溶接範囲から軸方向に外れている場合にも、孔２２が形成される取り付け片２１の強度を確保できる。換言すれば、孔２２が形成される取り付け片２１の強度が不足することを抑制することが可能である。 In the stabilizer bracket A, the attachment piece 21 in which the hole 22 is formed is reinforced by the extended piece 20 that is continuous with the axial connection piece 10. Therefore, the strength of the mounting piece 21 in which the hole 22 is formed can be ensured even when the stabilizer mounting hole 22 is deviated from the welding range of the connecting portion 1 in the axial direction. In other words, it is possible to suppress the strength of the attachment piece 21 in which the hole 22 is formed from being insufficient.
　以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。 The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment.

　例えば、上記の実施の形態では、スタビライザブラケットＡは、ナックルブラケットＮに溶接固定されている。これに代えて、スタビライザブラケットＡが緩衝器の外周Ｔに溶接固定されるようにしてもよく、また、スタビライザブラケットＡがナックルブラケットＮ以外の筒状体に溶接固定されるようにしてもよい。 For example, in the above embodiment, the stabilizer bracket A is fixed to the knuckle bracket N by welding. Instead, the stabilizer bracket A may be fixed by welding to the outer periphery T of the shock absorber, and the stabilizer bracket A may be fixed by welding to a tubular body other than the knuckle bracket N.
　また、上記の実施の形態では、ナックルブラケットＮは、一枚の板材をプレス成型することによって形成される。これに代えて、ナックルブラケットＮを、プレス成型以外の方法により形成してもよい。 In the above embodiment, the knuckle bracket N is formed by press molding a single plate material. Instead of this, the knuckle bracket N may be formed by a method other than press molding.
　また、上記の実施の形態では、連結部１は、軸方向連結片１０の他に、周方向連結片１１及び支持片１２を備えている。これに限らず、連結部１の構成や形状を適宜選択することができる。例えば、軸方向連結片１０と周方向連結片１１とが直接的に連なるのではなく、支持片１２を介して間接的に連なるようにして、軸方向連結片１０と周方向連結片１１と支持片１２とが三面角を構成しないようにしてもよい。また、取り付け部２を構成する延設片２０や取り付け片２１の形状や傾斜角度も適宜変更することができる。 In the above embodiment, the connecting portion 1 includes the circumferential connecting piece 11 and the support piece 12 in addition to the axial connecting piece 10. Not only this but the structure and shape of the connection part 1 can be selected suitably. For example, the axial connection piece 10 and the circumferential connection piece 11 are not directly connected to each other but indirectly connected via the support piece 12 to support the axial connection piece 10 and the circumferential connection piece 11. The piece 12 may not form a trihedral angle. Moreover, the shape and inclination angle of the extension piece 20 and the attachment piece 21 which comprise the attachment part 2 can also be changed suitably.
　また、上記の実施の形態では、延設片２０と軸方向連結片１０が傾斜して配置され、取り付け片２１と支持片１２が傾斜して配置される。しかしながら、延設片２０と軸方向連結片１０とが同一直線状に配置されるようにしてもよい。同様に、取り付け片２１と支持片１２とが同一直線上に配置されるようにしてもよい。 Further, in the above-described embodiment, the extending piece 20 and the axial connection piece 10 are arranged to be inclined, and the mounting piece 21 and the support piece 12 are arranged to be inclined. However, the extending piece 20 and the axial connection piece 10 may be arranged in the same straight line. Similarly, the attachment piece 21 and the support piece 12 may be arranged on the same straight line.
　本願は、２０１２年９月１８日に日本国特許庁に出願された特願２０１２－２０４１０９に基づく優先権を主張し、この出願の全ての内容は参照により本明細書に組み込まれる。 This application claims priority based on Japanese Patent Application No. 2012-204109 filed with the Japan Patent Office on September 18, 2012, the entire contents of which are incorporated herein by reference.
