Description
【０００１】[0001]
本考案は車両等に用いる緩衝器のシリンダの固定構造に関し、特にねじ込みタ イプのシリンダの緩みを防止する構造に関する。 The present invention relates to a structure for fixing a cylinder of a shock absorber used in a vehicle or the like, and more particularly to a structure for preventing loosening of a cylinder of a screw type.
【０００２】[0002]
車両等に用いる緩衝器として、実公平５−９５４６号公報に開示されているよ うにパイプ状のシリンダの外周にねじを形成し、このシリンダをタンクボディの 筒状取付け部に螺着したシリンダねじ込みタイプのものが知られている。 従来、このような緩衝器においては、シリンダが筒状取付け部に対して緩んで 脱落することなどを防止するために、図４に示すようにタンクボディの筒状取付 け部１０１とシリンダ１０２とを外部から止めねじ１０３で結合したり、或いは ロックナットを用いている。 As a shock absorber for use in a vehicle or the like, as disclosed in Japanese Utility Model Publication No. 5-9546, a screw is formed on the outer periphery of a pipe-shaped cylinder, and this cylinder is screwed into a tubular mounting portion of a tank body. Types are known. Conventionally, in such a shock absorber, as shown in FIG. 4, in order to prevent the cylinder from loosening and falling off from the cylindrical mounting portion, the cylindrical mounting portion 101 and the cylinder 102 of the tank body are provided. Is externally coupled with a set screw 103, or a lock nut is used.
【０００３】[0003]
上述した従来の緩衝器のように止めねじやロックナットでシリンダを固定する 構造にあっては、緩衝器の振動等によって止めねじやロックナットが緩んだ場合 には、シリンダが取付け部に対して緩んで脱落等するおそれがあり、また止めね じによりシリンダの変形を来し、ピストンのストロークを大きくとることができ ないことがある。 In the structure where the cylinder is fixed with a set screw or lock nut as in the conventional shock absorber described above, if the set screw or lock nut is loosened due to vibration of the shock absorber, the cylinder is attached to the mounting part. It may loosen and fall off, and the cylinder may be deformed by the stop screw, making it impossible to increase the stroke of the piston.

以下に本考案の実施例を添付図面に基づいて説明する。ここで、図１は本考案 に係るシリンダ固定構造を適用した緩衝器の半裁断面図、図２は同緩衝器の要部 断面図、図３は同緩衝器の要部正面図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a half sectional view of a shock absorber to which a cylinder fixing structure according to the present invention is applied, FIG. 2 is a cross sectional view of a main part of the shock absorber, and FIG. 3 is a front view of a main part of the shock absorber.
【０００７】 シリンダ１内には一端開口部側からキヤツプ２、ロツドガイド３、オイルシー ル４及びリバウンドラバー５等を介してピストンロッドである中空ロツド６を挿 通している。中空ロツド６の上端部にはシリンダ１内周面に摺接するピストン７ を装着して、ピストン７には減衰力発生用の油路８及び図示しない油路を形成し 、これらの油路８を開閉するバルブ９及び図示しない油路を開閉するバルブ１０ を装着している。A hollow rod 6 which is a piston rod is inserted into the cylinder 1 from one end opening side through a cap 2, a rod guide 3, an oil seal 4, a rebound rubber 5, and the like. At the upper end of the hollow rod 6, a piston 7 which is in sliding contact with the inner peripheral surface of the cylinder 1 is mounted, and an oil passage 8 for generating a damping force and an oil passage (not shown) are formed in the piston 7, and these oil passages 8 are formed. A valve 9 for opening and closing and a valve 10 for opening and closing an oil passage (not shown) are mounted.
【０００８】 また、中空ロッド６の下端部には車軸を取付けるための車軸取付け部材１２を 装着し、この車軸取付け部材１２の上側にスプリングシート１３を配設し、この スプリングシート１３上にストツパラバー１４を取付けている。一方シリンダ１ の他端開口部側は蓋部材１６を螺着し、この蓋部材１６の連結部１７にサブタン ク１８を連結するとともに、車体側に取付けるための車体取付け部１９を一体形 成している。Further, an axle mounting member 12 for mounting an axle is attached to a lower end portion of the hollow rod 6, a spring seat 13 is arranged on an upper side of the axle mounting member 12, and a stopper bar 14 is provided on the spring seat 13. Is installed. On the other hand, a lid member 16 is screwed on the other end opening side of the cylinder 1, a sub tank 18 is connected to a connecting portion 17 of the lid member 16, and a vehicle body mounting portion 19 for mounting on the vehicle body side is integrally formed. ing.
【０００９】 シリンダ１上端部外周にはカラー２０を嵌装し、このカラー２０の外周にはね じ２１を形成し、このねじ２１にスプリングシート２２を螺着して、ロックナッ ト２３にてロックするようにし、スプリングシート２２と前記スプリングシート １３との間に懸架ばね２４を介設している。A collar 20 is fitted on the outer periphery of the upper end of the cylinder 1, a screw 21 is formed on the outer periphery of the collar 20, and a spring seat 22 is screwed to the screw 21 and locked by a lock nut 23. A suspension spring 24 is provided between the spring seat 22 and the spring seat 13.
【００１０】 そして、蓋部材１６の下端面側に突起２６を一体的に形成し、カラー２０の上 端部側には蓋部材１６の突起２６が係合する切り欠き２７を形成して、これらの 突起２６及び切り欠き２７でカラー２０の蓋部材１６に対する回転を規制する回 り止め手段を構成している。A protrusion 26 is integrally formed on the lower end surface side of the lid member 16, and a notch 27 with which the protrusion 26 of the lid member 16 engages is formed on the upper end side of the collar 20. The protrusion 26 and the notch 27 constitute a rotation stopping means for restricting the rotation of the collar 20 with respect to the lid member 16.
【００１１】 更に、カラー２０の蓋部材１６側端部内周面に拡径部２８を形成することでカ ラー２０内周面に段差部を形成して、シリンダ１の外周面にカラー２０の拡径部 ２５終端の段差部にて係止される抜け止め部材であるストッパリング２９を嵌装 している。尚、抜け止め部材はストッパリング２９に限らない。Further, by forming the enlarged diameter portion 28 on the inner peripheral surface of the end portion of the collar 20 on the side of the lid member 16, a step portion is formed on the inner peripheral surface of the color 20 and the collar 20 expands on the outer peripheral surface of the cylinder 1. A stopper ring 29, which is a retaining member that is locked at the stepped portion at the end of the diameter portion 25, is fitted. The stopper member is not limited to the stopper ring 29.
【００１２】 以上のように構成した緩衝器においては、シリンダ１外周に嵌装したカラー２ ０は懸架ばね２４の復元力によって蓋部材１６側に押し付けられており、蓋部材 １６の突起２６とカラー２０の切り欠き２７が係合しているので、カラー２０は 蓋部材１６に対して回転することができない。In the shock absorber configured as described above, the collar 20 fitted on the outer periphery of the cylinder 1 is pressed against the lid member 16 side by the restoring force of the suspension spring 24, and the protrusion 26 of the lid member 16 and the collar 20. The collar 20 cannot rotate with respect to the lid member 16 because the notches 27 of the 20 are engaged.
【００１３】 したがって、緩衝器の振動等によってシリンダ１が蓋部材１６に対してねじ込 みが緩んできたような場合、シリンダ１外周面に嵌装したストッパリング２９が カラー２０内周面と拡径部２５内周面との段差部で係止されるので、それ以上シ リンダ１が回転して緩むことが防止される。Therefore, when the cylinder 1 is loosely screwed into the lid member 16 due to the vibration of the shock absorber or the like, the stopper ring 29 fitted on the outer peripheral surface of the cylinder 1 expands from the inner peripheral surface of the collar 20. Since it is locked at the step with the inner peripheral surface of the diameter portion 25, the cylinder 1 is prevented from rotating and loosening any further.
【００１４】 尚、上記実施例において、懸架スプリングのばね荷重を受けるカラー２０はふ たぶ剤１６の端面にて支持されているが、ストッパリング２９に支持されるよう にしてもよい。又カラーの外周にねじを形成する代りにカム面を形成し、スプリ ングシート側にこのカム面に係合するカムを設けるようにしてもよい。In the above embodiment, the collar 20 which receives the spring load of the suspension spring is supported by the end face of the lid agent 16, but it may be supported by the stopper ring 29. Instead of forming a screw on the outer periphery of the collar, a cam surface may be formed, and a cam that engages with this cam surface may be provided on the spring seat side.
【００１５】[0015]
以上に説明したように本考案によれば、シリンダ外周にカラーを嵌装し、この カラーの外周に懸架ばねの一端を支承するスプリングシートを回動自在に設け、 更に蓋部材とカラーとの間に回り止め手段を設け、カラーの内周面には段差部を 形成して、シリンダの外周面にカラーの段差部にて係止される抜け止め部材を設 けたので、蓋部材に螺着したシリンダが緩んで抜けることを確実に防止でき、し かも止めねじを用いた場合のようにシリンダの変形を来すことがなく、ピストン ストロークを大きくとることができる。 As described above, according to the present invention, the collar is fitted around the cylinder, and the spring seat that supports one end of the suspension spring is rotatably provided around the collar. Since a locking means is provided on the collar, a step is formed on the inner peripheral surface of the collar, and a retaining member that is locked by the step of the collar is provided on the outer peripheral surface of the cylinder, it is screwed to the lid member. The cylinder can be securely prevented from coming loose and coming out, and the piston stroke can be made large without deforming the cylinder unlike when using a set screw.
