Description

この発明は、緩衝器に関する。   The present invention relates to a shock absorber.

車両重量を支える懸架バネの下端を支承する懸架バネ受けを備えた緩衝器にあっては、たとえば、図4に示すように、複筒型に構成される緩衝器本体Dと、緩衝器本体Dにおける外筒1の外周側に設けた懸架バネ受け2とを備えてなり、この懸架バネ受け2は、いわゆるハット型に形成され、筒状の本体3と、本体3の下端から延設されるバネ受け部4とを備えている。   In a shock absorber provided with a suspension spring receiver that supports the lower end of a suspension spring that supports the vehicle weight, for example, as shown in FIG. The suspension spring receiver 2 provided on the outer peripheral side of the outer cylinder 1 is formed in a so-called hat shape, and extends from the cylindrical main body 3 and the lower end of the main body 3. And a spring receiving portion 4.

そして、この懸架バネ受け2は、外筒1の端部に被せられるとともに、本体3の上下2箇所を全周にわたりロールかしめを施すことによって、外筒1に固定されている(特許文献1参照)。
特許第3023958号公報(図1)
The suspension spring receiver 2 is fixed to the outer cylinder 1 by covering the end portion of the outer cylinder 1 and roll caulking the upper and lower portions of the main body 3 over the entire circumference (see Patent Document 1). ).
Japanese Patent No. 3023958 (FIG. 1)

上記のように、従来緩衝器では、懸架バネ受け2を緩衝器本体Dに固定に際して、懸架バネ受け2における本体3の上下2箇所を全周にわたりロールかしめを施しており、これにより懸架バネ受け2を緩衝器本体Dに強固に固定することができる。   As described above, in the conventional shock absorber, when the suspension spring receiver 2 is fixed to the shock absorber main body D, the upper and lower portions of the main body 3 of the suspension spring receiver 2 are subjected to caulking over the entire circumference. 2 can be firmly fixed to the shock absorber body D.

しかし、懸架バネ受けを強固にシリンダに取付けると、緩衝器の収縮行程において懸架バネが圧縮されて胴曲がりした際に、懸架バネ受けを介してシリンダを撓ませるモーメントが作用し、ピストンロッドに対しシリンダが撓んでピストンロッドの外周に摺接しピストンロッドとシリンダとの間をシールするシール部材に無理な圧力が作用し、シール部材の劣化を早めてしまう弊害がある。   However, if the suspension spring receiver is firmly attached to the cylinder, when the suspension spring is compressed and bent during the contraction stroke of the shock absorber, a moment that causes the cylinder to bend via the suspension spring receiver acts on the piston rod. There is an adverse effect that excessive pressure acts on the sealing member that bends the cylinder and slidably contacts the outer periphery of the piston rod and seals between the piston rod and the cylinder, thereby accelerating the deterioration of the sealing member.

また、単筒型の緩衝器に同様のロールカシメを施すと、シリンダを歪めてシリンダ内に摺動自在に挿入されるピストンの円滑な上下移動を妨げる恐れもある。   Further, when the same roll caulking is applied to the single cylinder type shock absorber, the cylinder may be distorted and the smooth vertical movement of the piston slidably inserted into the cylinder may be hindered.

そこで、本発明は上記の弊害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、懸架バネが胴曲がりして懸架バネ受けにモーメントが作用しても、シール部材の早期劣化を抑制可能な緩衝器を提供することである。   Therefore, the present invention was devised to improve the above-described adverse effects, and the object of the present invention is to provide an early seal member even if the suspension spring is bent and a moment acts on the suspension spring receiver. It is providing the buffer which can suppress degradation.

上記した目的を達成するために、本発明の課題解決手段は、シリンダに懸架バネの下端を支承する懸架バネ受けを備えた緩衝器において、懸架バネ受けが、シリンダ端部を覆う筒状の本体と、本体の外周側に設けた環状のバネ受け部と、本体に円周方向に沿って等間隔かつ本体内方に向けて突設されシリンダ外周に圧接する複数の凸部を備えてなり、該凸部は懸架バネの胴曲がりの際にシリンダに対しすべって上記胴曲がりを抑制することを特徴とする。   In order to achieve the above-mentioned object, the problem-solving means of the present invention is a shock absorber having a suspension spring receiver for supporting the lower end of a suspension spring on a cylinder, wherein the suspension spring receiver covers the cylinder end. And an annular spring receiving portion provided on the outer peripheral side of the main body, and a plurality of convex portions projecting toward the inner side of the main body at equal intervals along the circumferential direction and press-contacting the outer periphery of the cylinder, The convex portion slides against the cylinder when the suspension spring is bent to suppress the bending.

本発明によれば、懸架バネの胴曲がりが修正される分、懸架バネ受けに作用するモーメントが緩和されることになり、上記モーメントによるシリンダの撓みを抑制することができる。   According to the present invention, the moment acting on the suspension spring receiver is alleviated by the amount of correction of the bending of the suspension spring, and the bending of the cylinder due to the moment can be suppressed.

したがって、緩衝器が収縮する際、シリンダの撓みが抑制されるので、ピストンロッドに対しシリンダが撓んでピストンロッドの外周に摺接しピストンロッドとシリンダとの間をシールするシール部材に無理な圧力が作用することがなく、シール部材の劣化を早めることもなくなる。   Therefore, when the shock absorber contracts, the cylinder is restrained from bending, so that the cylinder is bent with respect to the piston rod, and the seal member that slides against the outer periphery of the piston rod and seals between the piston rod and the cylinder is subjected to excessive pressure. There is no effect and the deterioration of the seal member is not accelerated.

また、シリンダに撓みを生じさせにくくなるので、シリンダ内に摺動自在に挿入されるピストンの円滑な上下移動が保障され、これにより緩衝器の円滑な伸縮運動が保障される。   In addition, since it is difficult to cause the cylinder to bend, smooth vertical movement of the piston slidably inserted into the cylinder is ensured, thereby ensuring smooth expansion and contraction of the shock absorber.

以下に、図示した実施の形態に基づいて、この発明を説明する。図1は、一実施の形態における緩衝器の側面図である。図2は、一実施の形態における緩衝器の懸架バネ受けの縦断面図である。図3は、一実施の形態における緩衝器の懸架バネ受けの横断面図である。   The present invention will be described below based on the illustrated embodiment. FIG. 1 is a side view of a shock absorber according to an embodiment. FIG. 2 is a longitudinal sectional view of a suspension spring receiver of the shock absorber according to the embodiment. FIG. 3 is a cross-sectional view of the suspension spring receiver of the shock absorber according to the embodiment.

一実施の形態における緩衝器は、図1に示すように、緩衝器本体10と、懸架バネ受け20とで構成され、緩衝器本体10は、具体的に図示はしないが、シリンダ11と、シリンダ11内を作動室(図示せず)と気室と隔成するフリーピストン(図示せず)と、上記作動室を二つの油室(図示せず)を区画するピストン(図示せず)と、ピストンに連結されるピストンロッド12と備え、いわゆる単筒型油圧緩衝器として構成されている。   As shown in FIG. 1, the shock absorber according to the embodiment includes a shock absorber body 10 and a suspension spring receiver 20. Although not specifically shown, the shock absorber body 10 includes a cylinder 11 and a cylinder. 11, a free piston (not shown) that separates the working chamber (not shown) and the air chamber, a piston (not shown) that divides the working chamber into two oil chambers (not shown), The piston rod 12 is connected to the piston, and is configured as a so-called single cylinder type hydraulic shock absorber.

そして、ピストンロッド12は、シリンダ11の図1中上端内周に圧入等により固定される環状のロッドガイド13により軸支され、さらに、ロッドガイド13とシリンダ11の上方開口端をかしめて内周側に折り曲げることによって形成される折り曲げ部11aとの間には環状のシール部材14が介装されている。   The piston rod 12 is pivotally supported by an annular rod guide 13 that is fixed to the inner periphery of the upper end of the cylinder 11 in FIG. 1 by press fitting or the like. Further, the rod guide 13 and the upper open end of the cylinder 11 are crimped. An annular seal member 14 is interposed between the bent portion 11a formed by bending to the side.

このシール部材14は、環状のシール本体15と、シール本体15の内周側下面に設けたピストンロッド12の外周に摺接する内周側シール部16と、シール本体15の内周側上面に設けたピストンロッド12の外周に摺接するダストシール部17と、シール本体15の外周側下面に設けたシリンダ11の内周に当接する外周側シール部18とを備えて構成され、このシール部材14でシリンダ11とピストンロッド12との間がシールされ、シリンダ10内は油密状態に維持されている。   The seal member 14 is provided on an annular seal body 15, an inner peripheral seal portion 16 that is in sliding contact with the outer periphery of the piston rod 12 provided on the inner peripheral lower surface of the seal main body 15, and an inner peripheral upper surface of the seal main body 15. The dust seal portion 17 that is in sliding contact with the outer periphery of the piston rod 12 and the outer peripheral side seal portion 18 that is in contact with the inner periphery of the cylinder 11 provided on the lower surface on the outer periphery side of the seal body 15 are configured. 11 and the piston rod 12 are sealed, and the inside of the cylinder 10 is maintained in an oil-tight state.

なお、この単筒型油圧緩衝器として構成される緩衝器については、周知であるので詳しくは説明しないが、ピストンには上記各油室を連通する通路が形成されるとともに、この通路の途中にオリフィスや減衰バルブ等の減衰力発生要素が設けられ、緩衝器が伸縮して作動油が上記各油室を交流する際に上記減衰力発生要素によって生じる各油室内の圧力差と、各油室に面するピストンの受圧面積差により所定の減衰力を発生するようになっている。   The shock absorber configured as the single cylinder type hydraulic shock absorber is well known and will not be described in detail, but the piston is formed with a passage communicating with each of the oil chambers, and in the middle of the passage. Damping force generating elements such as orifices and damping valves are provided, and when the shock absorber expands and contracts and hydraulic fluid exchanges the oil chambers, the pressure difference in the oil chambers generated by the damping force generating elements and the oil chambers A predetermined damping force is generated by the pressure receiving area difference between the pistons facing the cylinder.

他方、懸架バネ受け20は、筒状の本体21と、本体21の図1および図2中下端から延設される環状のバネ受け部22と、本体21に円周方向に沿って等間隔かつ本体21内方に向けて突設される3つの凸部23とを備えて構成されて、略ハット形状に形成されている。   On the other hand, the suspension spring receiver 20 includes a cylindrical main body 21, an annular spring receiver 22 extending from the lower end of the main body 21 in FIGS. 1 and 2, and the main body 21 at equal intervals along the circumferential direction. The main body 21 is provided with three convex portions 23 projecting inward, and is formed in a substantially hat shape.

また、本体21の上端開口端は内側に向けて水平に折り曲げられて水平部24が形成され、この水平部24の外周部には等間隔を持って窪み25が3つ形成されるとともに、上記水平部24の上面には、ドーナツ板形状のバンプストッパ26が溶接により取付けられている。   Further, the upper end opening end of the main body 21 is bent horizontally inward to form a horizontal portion 24, and three recesses 25 are formed on the outer peripheral portion of the horizontal portion 24 at equal intervals. A donut-shaped bump stopper 26 is attached to the upper surface of the horizontal portion 24 by welding.

そして、上記のように構成された懸架バネ受け20は、緩衝器本体10におけるシリンダ11の図1中上端部に被せるようにして取付けられるが、その際に、水平部24とバンプストッパ26の軸芯部にピストンロッド12を挿通させ、さらに、本体21内にシリンダ11の上端部を挿入し、最終的には懸架バネ受け20の内部にシリンダ11の図1中上端が上記窪み25の下端に当接するまで挿入される。   The suspension spring receiver 20 configured as described above is attached so as to cover the upper end portion of the shock absorber body 10 in FIG. 1 of the cylinder 11. At this time, the shaft of the horizontal portion 24 and the bump stopper 26 is attached. The piston rod 12 is inserted through the core, and the upper end of the cylinder 11 is inserted into the main body 21. Finally, the upper end of the cylinder 11 in FIG. It is inserted until it abuts.

このとき、上記した各凸部23は、図3に示すように、その各々の内端を通る仮想円Vの直径がシリンダ11の外周径より若干小さくなるように設定されているが、詳しくは、懸架バネ受け20に後述するモーメントが作用する際に、凸部23とシリンダ11との間にすべりを生じて、懸架バネ受け20がシリンダ11に対し傾ぐこと可能なように設定される。   At this time, as shown in FIG. 3, each of the convex portions 23 described above is set so that the diameter of the virtual circle V passing through each inner end thereof is slightly smaller than the outer diameter of the cylinder 11. When the moment described below is applied to the suspension spring receiver 20, a slip is generated between the convex portion 23 and the cylinder 11 so that the suspension spring receiver 20 can be tilted with respect to the cylinder 11.

それゆえ、上記のように懸架バネ受け20の本体21内にシリンダ11の上端部を挿入する際、各凸部23は、シリンダ11の外周に圧接されることになり、これら凸部23は、シリンダ11を挟持する。   Therefore, when the upper end portion of the cylinder 11 is inserted into the main body 21 of the suspension spring receiver 20 as described above, each convex portion 23 is brought into pressure contact with the outer periphery of the cylinder 11. The cylinder 11 is clamped.

そして、上記したようにシリンダ11に懸架バネ受け20を取付けておいて、懸架バネ19をピストンロッド12の上端側に設けた図示しない上方側の懸架バネ受けと懸架バネ受け20におけるバネ受け部21との間に介装させる。   Then, the suspension spring receiver 20 is attached to the cylinder 11 as described above, and an upper suspension spring receiver (not shown) in which the suspension spring 19 is provided on the upper end side of the piston rod 12 and the spring receiver 21 in the suspension spring receiver 20. Intervene between.

なお、ピストンロッド12の上端外周側には図示しないバンプクッションが設けられており、この緩衝器が収縮する際に、このバンプクッションはバンプストッパ26に当接して緩衝器の最収縮時の衝撃を緩和する。   A bump cushion (not shown) is provided on the outer peripheral side of the upper end of the piston rod 12. When the shock absorber contracts, the bump cushion abuts against the bump stopper 26 so that the shock at the time of the maximum contraction of the shock absorber is applied. ease.

さて、上述のように構成される緩衝器にあっては、緩衝器が収縮する際、上記懸架バネ19は圧縮されるが、このとき、そのコイル状線材が全体わたり均一に製造することが困難であることなどにより、懸架バネ19は圧縮に伴って横方向に折れ曲がる状態、いわゆる胴曲がりを生じる。   In the shock absorber configured as described above, when the shock absorber contracts, the suspension spring 19 is compressed. At this time, it is difficult to produce the coiled wire material uniformly throughout. For example, the suspension spring 19 bends in the lateral direction as it is compressed, so-called torso.

この胴曲がりにより、懸架バネ19の線材は全体に渡り一様に圧縮されず、懸架バネ19を圧縮する力に対してある部分で過剰に圧縮し、別の部分ではは圧縮不足となり、懸架バネ19の下端を支承している懸架バネ受け20におけるバネ受け部22には、一様に力が作用せず、懸架バネ受け20には、図1中懸架バネ受け20を横方向に回転させるようなモーメントが発生する。   Due to this bending, the wire rod of the suspension spring 19 is not uniformly compressed over the entire surface, and the suspension spring 19 is excessively compressed in one portion with respect to the compression force, and the other portion is under-compressed. A force is not applied uniformly to the spring receiving portion 22 of the suspension spring receiver 20 that supports the lower end of 19 so that the suspension spring receiver 20 is rotated in the lateral direction in FIG. Moment occurs.

ここで、上記懸架バネ受け20は、上記凸部23のみでシリンダ11に固定されているだけであるので、上記モーメントによって上記凸部23とシリンダ11との間にすべりが生じ、シリンダ11に対し懸架バネ19の胴曲がりをある程度修正するような向きに釣り合いを保つ位置まで傾ぐ。   Here, since the suspension spring receiver 20 is only fixed to the cylinder 11 with only the convex portion 23, a slip occurs between the convex portion 23 and the cylinder 11 due to the moment, and the cylinder 11 The suspension spring 19 is tilted to a position where the balance is maintained in such a direction as to correct the torsion of the trunk spring 19 to some extent.

すなわち、懸架バネ受け20にあっては、本体21の上部付近を中心として振り子のようにバネ受け部22を左右に振らせることが可能となっている。   That is, in the suspension spring receiver 20, the spring receiver 22 can be swung left and right like a pendulum around the upper part of the main body 21.

すると、懸架バネ19の胴曲がりが修正される分、懸架バネ受け20に作用するモーメントが緩和されることになり、上記モーメントによるシリンダ11の撓みを抑制することができる。   As a result, the moment acting on the suspension spring receiver 20 is relieved by the correction of the bending of the suspension spring 19, and the bending of the cylinder 11 due to the moment can be suppressed.

したがって、緩衝器が収縮する際、シリンダ11の撓みが抑制されるので、ピストンロッド12に対しシリンダ11が撓んでピストンロッド12の外周に摺接しピストンロッド12とシリンダ11との間をシールするシール部材14に無理な圧力が作用することがなく、シール部材14の劣化を早めることもなくなる。   Therefore, when the shock absorber contracts, the cylinder 11 is restrained from being bent, so that the cylinder 11 bends with respect to the piston rod 12 and is brought into sliding contact with the outer periphery of the piston rod 12 to seal between the piston rod 12 and the cylinder 11. Unreasonable pressure does not act on the member 14, and the deterioration of the seal member 14 is not accelerated.

また、シリンダ11に撓みを生じさせにくくなるので、シリンダ内に摺動自在に挿入されるピストンの円滑な上下移動が保障され、これにより緩衝器の円滑な伸縮運動が保障される。   Moreover, since it becomes difficult to cause the cylinder 11 to bend, smooth vertical movement of the piston slidably inserted into the cylinder is ensured, thereby ensuring smooth expansion and contraction of the shock absorber.

さらに、懸架バネ受け20がシリンダ11に当接している部位は、各凸部23および窪み25の下端のみとなり、それ以外の部位では懸架バネ受け20とシリンダ11との間に隙間が生じていることとなる。   Further, the portion where the suspension spring receiver 20 is in contact with the cylinder 11 is only the lower end of each convex portion 23 and the recess 25, and a gap is generated between the suspension spring receiver 20 and the cylinder 11 in other portions. It will be.

したがって、懸架バネ受け20とシリンダ11との間に埃や水滴等が侵入しても、上記隙間を介して懸架バネ受け20の外方に排出されることになり、埃や水滴等がシリンダ11と懸架バネ受け20との間に留まってシリンダ11と懸架バネ受け20の表面を劣化させることがない。   Therefore, even if dust or water drops enter between the suspension spring receiver 20 and the cylinder 11, the dust or water drops are discharged to the outside of the suspension spring receiver 20 through the gap. And the surface of the cylinder 11 and the suspension spring receiver 20 are not deteriorated.

なお、上記したところでは、凸部23をそれぞれ3箇所等間隔に設けているが、2箇所に設けるとしてもよく、上記モーメントの緩和を行える限りにおいて、凸部23をそれぞれ4個以上等間隔に設けることも可能であり、また、懸架バネ19の胴曲がりの方向が常に一定であれば、胴曲がりする方向線に対し直角に交わる線上に凸部23をそれぞれ2箇所設ける場合には、凸部23がその位置を保ったままですべりを生じて懸架バネ受け20を振り子のように運動させることができるので、シリンダ11の外周を必要以上に傷めてしまうということがない。   In the above description, the convex portions 23 are provided at three equal intervals, but may be provided at two locations. As long as the moment can be reduced, four or more convex portions 23 are provided at equal intervals. In addition, if the direction of the torsion of the suspension spring 19 is always constant, when the two protrusions 23 are provided on a line that intersects at right angles to the direction of the bending direction, Since the slide 23 is kept in its position and the suspension spring receiver 20 can be moved like a pendulum, the outer periphery of the cylinder 11 is not damaged more than necessary.

また、個々の凸部23のシリンダ11の外周に当接する円周方向幅、軸方向幅および面圧は、適宜、上記懸架バネ19の胴曲がりにより生じるであろうモーメントの大きさ、すなわち、懸架バネ19の仕様によって設定されればよい。   In addition, the circumferential width, axial width, and surface pressure that contact the outer periphery of the cylinder 11 of each convex portion 23 are appropriately determined according to the magnitude of the moment that will be generated by the bending of the suspension spring 19, that is, the suspension. What is necessary is just to set with the specification of the spring 19. FIG.
