【産業上の利用分野】[Industrial applications]

本考案は、ショックアブソーバのピストン部又はベースバルブのバルブケース 上に開閉自在に配置したチェック弁の使用に適するショックアブソーバのリーフ バルブに関する。 The present invention relates to a leaf valve of a shock absorber suitable for use with a check valve which is openably and closably arranged on a piston part of a shock absorber or a valve case of a base valve.

【0002】[0002]

【従来の技術】[Prior art]

この種のリーフバルブとして、例えば、特開平2−97740号公報、実公平 3−48431号公報に開示されたものが知られている。 Known leaf valves of this type are disclosed, for example, in Japanese Patent Laid-Open No. 2-97740 and Japanese Utility Model Publication No. 3-48431.

【0003】 このリーフバルブは、図5に示す構造となっている。This leaf valve has a structure shown in FIG.

【0004】 即ち、リーフバルブ1は、外側環状部2と、中央の内側環状部たる支持環3と 、外側環状部2と支持環3を接続する支持片4とから構成されている。That is, the leaf valve 1 includes an outer annular portion 2, a support ring 3 that is a central inner annular portion, and a support piece 4 that connects the outer annular portion 2 and the support ring 3.

【0005】 そして、該リーフバルブ1は、ピストン又はベースバルブのバルブケース上に ノンリタンスプリングで押えられながら配置され、例えばピストンの外側圧ポー ト上に外側環状部2が開閉自在に配置される。The leaf valve 1 is arranged on a valve case of a piston or a base valve while being pressed by a non-return spring. For example, an outer annular portion 2 is arranged to be openable and closable on an outer pressure port of the piston. .

【0006】 支持環3は、中央の孔を介して例えばピストンロッドに挿入され、支持環3と 外側環状部2との間に形成された開口部6はピストンの内側伸ポートと対向して いる。The support ring 3 is inserted into, for example, a piston rod through a central hole, and an opening 6 formed between the support ring 3 and the outer annular portion 2 faces the inner extension port of the piston. .

【0007】 従って、ピストンの伸長時にはピストン上方の油室の油が開口部6より内側伸 ポートを介してピストン下方の伸側バルブに作用して伸側減衰力を発生し、圧縮 作動時にはピストン下方の油室の油が外側圧ポートより外側環状部2を押し開い て上方の油室に流出する。Therefore, when the piston is extended, the oil in the oil chamber above the piston acts on the extension side valve below the piston from the opening 6 via the inside extension port to generate the extension side damping force, and during compression operation, the piston below The oil in the oil chamber pushes the outer annular portion 2 open from the outer pressure port and flows out to the upper oil chamber.

【0008】 即ち、上記リーフバルブ1は、チェック弁として利用される。That is, the leaf valve 1 is used as a check valve.

【0009】[0009]

【考案が解決しようとする課題】[Problems to be solved by the device]

上記のリーフバルブは、加工現場からショックアブソーバの組付現場へ搬送す る場合、例えば、多数のリーフバルブを篭に入れて行なう為に各リーフバルブが 動いて互いにからみ合う場合が生じる。 When the leaf valves described above are transported from the processing site to the shock absorber assembly site, for example, since many leaf valves are put in a basket, each leaf valve may move and entangle with each other.

【0010】 図6に示すように、例えば、一方のリーフバルブAの外側環状部2が他方のリ ーフバルブBに対して斜め方向から衝突すると、一方のリーフバルブAの外側環 状部2の外縁部が他方リリーフバルブBの開口部6に侵入し、他方のリーフバル ブBの外側環状部2と支持環3との間に挾み込まれ他方のリーフバルブの支持環 3を押し上げてしまう。As shown in FIG. 6, for example, when the outer annular portion 2 of one leaf valve A collides with the other leaf valve B from an oblique direction, the outer edge of the outer annular portion 2 of the one leaf valve A. The portion of the leaf valve penetrates the opening 6 of the other relief valve B and is caught between the outer annular portion 2 of the other leaf valve B and the support ring 3 and pushes up the support ring 3 of the other leaf valve.

【0011】 同様に、図7に示すように、二つのリーフバルブA,Bがからみ合うと、他方 のリーフバルブBの支持環3が一方のリーフバルブAの開口部6に侵入してしま う場合がある。Similarly, as shown in FIG. 7, when the two leaf valves A and B are entangled with each other, the support ring 3 of the other leaf valve B intrudes into the opening 6 of the one leaf valve A. There are cases.

【0012】 この為、二つのリーフバルブA,Bがからみ合うと支持環3が傾斜しその平坦 度を失うため、そのまま使用すると所望のリーフバルブとしての機能を十分に発 揮できなくなるおそれがある。Therefore, when the two leaf valves A and B are entangled with each other, the support ring 3 tilts and loses its flatness. Therefore, if it is used as it is, the desired leaf valve function may not be sufficiently exerted. .

【0013】 又、上記のように複数のリーフバルブがからみ合うとその分離作業が困難とな り、ショックアブソーバの組付作業に影響をおよぼし、特に自動組付工程を一時 停止しなければならなくなる。Further, when a plurality of leaf valves are entangled with each other as described above, the separation work becomes difficult, which affects the shock absorber assembly work, and in particular, the automatic assembly process must be temporarily stopped. .

【0014】 そこで、本考案の目的は、多数のリーフバルブを同時に搬送する場合に互いに からみ合って挾み込まれるのを防止し、併せて平坦度を失わないようにするショ ックアブソーバのリーフバルブを提供することである。Therefore, an object of the present invention is to provide a leaf valve for a shock absorber, which prevents the leaf valves from being caught and caught in each other when transporting a large number of leaf valves at the same time, and at the same time, does not lose flatness. Is to provide.

【課題を解決するための手段】[Means for Solving the Problems]

上記の目的を達成するため、本考案の構成は、シリンダ内に隔壁部材を設け、 隔壁部材はシリンダ内に二つの油室を区画し、二つの油室は隔壁部材に設けた外 側ポートと内側ポートを介して連通し、隔壁部材の端部に外側シート部と内側シ ート部とを形成し、各シート部上に前記外側ポートを開閉するリーフバルブが設 けられているショックアブソーバに於て、リーフバルブは外側シート部上に支持 されて外側ポートを閉塞する外側環状部と、内側シート部上に支持される内側環 状部と、内側ポートに対向する開口部と、外側環状部と内側環状部とを接続する ばね力を備えた支持片と、外側環状部の内周又は内側環状部の外周の任意の位置 から開口部に向けて突設させた複数の突起とで構成させ、隣接する二つの突起間 又は突起と支持片間の寸法を内側環状部の直径より小さくさせたことを特徴とす るものである。 In order to achieve the above object, the structure of the present invention is to provide a partition member in a cylinder, the partition member defines two oil chambers in the cylinder, and the two oil chambers are provided with an outer port provided in the partition member. A shock absorber in which an outer seat portion and an inner seat portion are formed at the end of the partition member, which communicate with each other through the inner port, and a leaf valve for opening and closing the outer port is provided on each seat portion. In the leaf valve, the leaf valve is supported on the outer seat portion to close the outer port, the inner annular portion supported on the inner seat portion, the opening facing the inner port, and the outer annular portion. And a support piece having a spring force for connecting the inner ring portion and the inner ring portion, and a plurality of protrusions projecting from any position on the inner periphery of the outer ring portion or the outer periphery of the inner ring portion toward the opening. , Between two adjacent protrusions or support with protrusions A feature and be shall that the dimension between were smaller than the diameter of the inner annular portion.

【0016】[0016]

【作用】[Action]

二つのリーフバルブが斜め方向から衝突しても一方のリーフバルブの開口部に 他方のリーフバルブの外側環状部の外縁部が侵入するのを突起が阻止する。 Even if the two leaf valves collide from an oblique direction, the projection prevents the outer edge portion of the outer annular portion of the other leaf valve from entering the opening portion of the one leaf valve.

【0017】 又二つの突起間又は突起と支持片間の寸法が内側環状部の直径より小さいから 一方のリーフバルブの開口部に他方のリーフバルブの内側環状部が侵入するのを 防止する。Further, since the dimension between the two protrusions or between the protrusion and the support piece is smaller than the diameter of the inner annular portion, the inner annular portion of the other leaf valve is prevented from entering the opening of one leaf valve.

【0018】[0018]

【実施例】【Example】

以下、図にもとづいて本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.

【0019】 図1は、一実施例に係るリーフバルブを示し、図2はこのリーフバルブをチェ ック弁としてベースバルブ部に利用した例を示す。FIG. 1 shows a leaf valve according to one embodiment, and FIG. 2 shows an example in which this leaf valve is used as a check valve in a base valve portion.

【0020】 但し、リーフバルブは、ピストン部に配置したチェック弁、減衰弁にも利用で きる。However, the leaf valve can also be used as a check valve and a damping valve arranged in the piston portion.

【0021】 ショックアブソーバのベースバルブは、隔壁部材たるバルブケース8を有し、 バルブケース8は、シリンダ9内のピストン下方の油室10をアウターチューブ 11内のリザーバ側油室12に区画し、二つの油室10,12は、バルブケース 8に形成した外側ポート13と内側ポート14を介して連通している。The base valve of the shock absorber has a valve case 8 that is a partition member. The valve case 8 divides an oil chamber 10 below a piston in a cylinder 9 into a reservoir-side oil chamber 12 in an outer tube 11, The two oil chambers 10 and 12 communicate with each other through an outer port 13 and an inner port 14 formed in the valve case 8.

【0022】 バルブケース8の上側端部には外側シート部16と内側シート部17が形成さ れ、各シート部16,17上にはチェック弁としてリーフバルブ1が配置されて いる。An outer seat portion 16 and an inner seat portion 17 are formed at an upper end portion of the valve case 8, and a leaf valve 1 is arranged as a check valve on each of the seat portions 16 and 17.

【0023】 内側ポート14の下部には圧側減衰バルブ15が開閉自在に設けられている。A compression-side damping valve 15 is provided below the inner port 14 so as to be openable and closable.

【0024】 リーフバルブ1は、図1に示すように、外側シート部16上に支持されて外側 ポート13を閉塞する外側環状部2と、内側シート部17上に支持される内側環 状部たる支持環3と、内側ポート14に対向する開口部6と、外側環状部2と内 側環状部3とを接続するばね力を備えた支持片4と、外側環状部の内周に等間隔 で開口部6に向けて突設させた三つの突起19とで構成されている。As shown in FIG. 1, the leaf valve 1 is an outer annular portion 2 that is supported on the outer seat portion 16 and closes the outer port 13, and an inner annular portion that is supported on the inner seat portion 17. The support ring 3, the opening 6 facing the inner port 14, the support piece 4 having a spring force for connecting the outer annular portion 2 and the inner annular portion 3, and the inner periphery of the outer annular portion at equal intervals. It is composed of three protrusions 19 projecting toward the opening 6.

【0025】 この為、圧縮作動時には油室10の油が開口部6と内側ポート14とを介して 圧側減衰バルブ15に作用し、これを開いて圧側減衰力を発生する。Therefore, during the compression operation, the oil in the oil chamber 10 acts on the compression side damping valve 15 via the opening 6 and the inner port 14, and opens it to generate the compression side damping force.

【0026】 伸長作動時にはリザーバ側油室12の油が外側ポート13を介してリーフバル ブ1に作用し、これを押し開いて油室10に流出する。During the extension operation, the oil in the reservoir side oil chamber 12 acts on the leaf valve 1 via the outer port 13, pushes it open, and flows out to the oil chamber 10.

【0027】 上記支持片4において、当該支持片4に対する外側環状部2の接続個所両側に 切り溝7,7を設け、当該切り溝7,7の深さにより支持片4の長さLを調整し 、これにより剛性の変更が可能で、理想的な開口圧力が得られる。In the support piece 4, cut grooves 7, 7 are provided on both sides of the connection portion of the outer annular portion 2 with respect to the support piece 4, and the length L of the support piece 4 is adjusted by the depth of the cut grooves 7, 7. However, this makes it possible to change the rigidity and obtain an ideal opening pressure.

【0028】 即ち、支持片4の長さを調整することによりチェック弁たるリーフバルブ1の 開口圧力を適正な値にでき、車両走行中におけるショックアブソーバのピストン ロッドが加振され、乗員に不快な音として聞える200乃至400Hzの振動を 抑制することができる。That is, by adjusting the length of the support piece 4, the opening pressure of the leaf valve 1, which is a check valve, can be adjusted to an appropriate value, and the piston rod of the shock absorber is vibrated while the vehicle is running, which is uncomfortable for the occupant. It is possible to suppress vibration of 200 to 400 Hz which can be heard as sound.

【0029】 上記突起19において、隣接する二つの突起19,19間の寸法Eは支持環3 の直径Fより小さ(F>E)形成され、又突起19の先端と支持環3の外側との 間に隙間δを形成している。この隙間δの寸法はリーフバルブ1の板厚より小さ く成形するのが好ましい。In the projection 19, the dimension E between two adjacent projections 19 and 19 is formed smaller than the diameter F of the support ring 3 (F> E), and the tip of the projection 19 and the outside of the support ring 3 are formed. A gap δ is formed between them. It is preferable that the size of the gap δ be smaller than the thickness of the leaf valve 1.

【0030】 突起19を設けても隙間δがある限り、支持板4の長さLと巾Dが同じであれ ば、支持環3は突起19と干渉せず、ばね定数は同じである。Even if the protrusion 19 is provided, as long as there is a gap δ, if the length L and the width D of the support plate 4 are the same, the support ring 3 does not interfere with the protrusion 19 and the spring constant is the same.

【0031】 突起19を設け、隙間δを小さくしておけば、二つのリーフバルブ1,1同志 が斜め方向から衝突しても、一方のリーフバルブ1の開口部6に他方のリーフバ ルブの外側緩衝部2の外縁部が侵入することはなく、従って一方のリーフバルブ 1の支持環3の下側に挾み込まれてこの支持環3を押し上げ、平坦度を失わせる ようなことを防止できる。If the protrusion 19 is provided and the gap δ is made small, even if the two leaf valves 1 and 1 collide with each other from an oblique direction, the opening 6 of one leaf valve 1 is placed outside the other leaf valve. The outer edge portion of the buffer portion 2 does not enter, and therefore it is possible to prevent the support ring 3 from being pinched under the support ring 3 of one leaf valve 1 and pushing up the support ring 3 to lose the flatness. .

【0032】 同じく、突起19,19間の寸法が支持環3の直径より小さいから、突起19 ,19間の開口部6に他方のリーフバルブ1の支持環3が侵入して挾み込まれる ようなことも防止できる。Similarly, since the dimension between the projections 19 and 19 is smaller than the diameter of the support ring 3, the support ring 3 of the other leaf valve 1 may be inserted and inserted into the opening 6 between the projections 19 and 19. It can also prevent things.

【0033】 図3、図4は、本考案の他の実施例を示し、これは支持片4,4を二つ設け、 両側又は片側に突起19,19を二つ設け、支持片4と突起19との間の寸法E を支持環3の直径Fより小さくさせたものである。3 and 4 show another embodiment of the present invention, in which two supporting pieces 4 and 4 are provided, and two protrusions 19 and 19 are provided on both sides or one side, and the supporting piece 4 and the protrusions are provided. 19 is smaller than the diameter F of the support ring 3.

【0034】 その他の作用、効果は図1と同じである。Other functions and effects are the same as those in FIG.

【0035】 尚、突起19は支持環3の外周に突設してもよい。The protrusions 19 may be provided on the outer circumference of the support ring 3.

【0036】[0036]

【考案の効果】[Effect of device]

本考案によれば、次の効果がある。 The present invention has the following effects.

【0037】 1)外側環状部の内周又は内側環状部の外周に複数の突起を突設し、これら突 起間の寸法、又は突起と支持片との間の寸法を内側環状部の直径より小さく形成 させたから、二つのリーフバルブがからみ合ったり、斜め方向から衝突した場合 でも、一方のリーフバルブの開口部内に他方のリーフバルブの外側環状部又は内 側環状部が侵入するのを突起が阻止する。1) A plurality of protrusions are provided on the inner periphery of the outer annular portion or the outer periphery of the inner annular portion, and the dimension between these protrusions or the dimension between the protrusion and the support piece is determined by the diameter of the inner annular portion. Since it is made small, even if two leaf valves entangle or collide from an oblique direction, the protrusion prevents the outer annular portion or inner annular portion of the other leaf valve from entering the opening of one leaf valve. Block.

【0038】 この為、一方のリーフバルブが他方のリーフバルブに挾み込まれず、内側環状 部が押し上げられることがなく、平坦度を失わない。Therefore, one leaf valve is not caught in the other leaf valve, the inner annular portion is not pushed up, and the flatness is not lost.

【0039】 従ってリーフバルブの機能を失うことが防止される。Therefore, loss of function of the leaf valve is prevented.

【0040】 2)支持片に対する外側環状部の接続個所両側に切り溝を設け実施例によれば 、この切り溝の深さ分支持片の長さを長くすることかできる。2) By providing the cut grooves on both sides of the connection portion of the outer annular portion with respect to the support piece, according to the embodiment, the length of the support piece can be increased by the depth of the cut groove.

【0041】 この為、切り溝を設けて支持片の長さを調整するから、リーフバルブの外径寸 法、外側環状部と内側環状部との寸法、開口部の巾には何ら影響を与えずに済む ことになる。Therefore, since the kerf is provided to adjust the length of the support piece, it has no influence on the outer diameter dimension of the leaf valve, the dimensions of the outer and inner annular portions, and the width of the opening. It will not be necessary.

【0042】 逆に言えば、これらの部材の寸法に関係なく支持片の長さを設定できるから、 チェック弁として利用したときその開口圧力を適正な値にでき、車両走行中にお けるショックアブソーバのピストンロッドが加振され、乗員に不快な音として聞 える200乃至400Hzの振動を抑制することができる。Conversely, since the length of the support piece can be set regardless of the dimensions of these members, the opening pressure of the check valve can be set to an appropriate value when used as a check valve, and the shock absorber can be used while the vehicle is running. The piston rod is vibrated, and the vibration of 200 to 400 Hz which is heard as an unpleasant sound to the occupant can be suppressed.
