Description

本発明は、自動車用に装備されるエアサスペンションのエア封止用プロテクタに関する。 The present invention relates to an air sealing protector for an air suspension equipped for an automobile.

自動車用のエアサスペンションは、一般に自動車の懸架装置に用いられるものであり、ピストンロッドの伸長、縮小に追従して振動を減衰するダンパーと、圧縮エアが封入されたエアバックとを備えて構成されている(特許文献1〜2)。 Air suspensions for automobiles are generally used for suspension devices of automobiles, and are configured to include a damper that attenuates vibration by following the expansion and contraction of a piston rod and an airbag filled with compressed air. (Patent Documents 1 and 2).

この種のエアサスペンションとしては、例えば図8および図9に示すように、ダンパー11の上部にエアバック12を備え、エアバック12の下端部12aを、ダンパー11に装着した円筒状のシール部材13に気密的に連結して、当該エアバック12内のエアを封止する形式のエアサスペンション10が知られている。なお、符号13aは、シール部材13の上方に設けられた円筒状部材である。 As an air suspension of this type, for example, as shown in FIGS. 8 and 9, a cylindrical sealing member 13 is provided with an airbag 12 on the upper part of the damper 11, and the lower end portion 12a of the airbag 12 is attached to the damper 11. There is known an air suspension 10 of a type that is airtightly connected to and seals the air in the airbag 12. Reference numeral 13a is a cylindrical member provided above the seal member 13.

この従来のエアサスペンション10においては、ゴムベローズからなるエアバック12の下端部12aに、当該下端部12aの外側から嵌合する金属製のリング部材14を備えて、ダンパー11との連結部を補強している。リング部材14の内周側にはエアバック12の下端部12aが位置しており、このリング部材14をシール部材13に連結する場合は、当該下端部12aが、シール部材13の円筒状部材13aと密着して、気密封止が担保されている。なお、リング部材14にはアルミ製などのものが用いられている。 In the conventional air suspension 10, the lower end portion 12a of the airbag 12 made of rubber bellows is provided with a metal ring member 14 fitted from the outside of the lower end portion 12a to reinforce the connecting portion with the damper 11. are doing. The lower end portion 12a of the airbag 12 is located on the inner peripheral side of the ring member 14, and when the ring member 14 is connected to the seal member 13, the lower end portion 12a is the cylindrical member 13a of the seal member 13. The airtight seal is guaranteed. The ring member 14 is made of aluminum or the like.

また、本例の場合、前記一対の下部保持部材4,5は、組み合わされてリング形状を形成し、このリング形状の内径が、前記円筒状のシール部材13の外径よりも小さく設けられている。 Further, in the case of this example, the pair of lower holding members 4 and 5 are combined to form a ring shape, and the inner diameter of the ring shape is provided smaller than the outer diameter of the cylindrical seal member 13. There is.

さらに本例では、前記一対の下部保持部材4,5は、その下部に、組み合わされてリング形状を形成する鍔部4c,5cを備えており、この鍔部4c,5cにおけるリング形状の内径が、前記円筒状のシール部材13の外径よりも小さく設けられている。 Further, in this example, the pair of lower holding members 4 and 5 are provided with collar portions 4c and 5c which are combined to form a ring shape at the lower portion thereof, and the inner diameter of the ring shape in the collar portions 4c and 5c is , Which is smaller than the outer diameter of the cylindrical seal member 13.

上述したように、下部保持部材4,5が組み合わされてリング形状を形成し、このリング形状の内径が、前記円筒状のシール部材13の外径よりも小さく設けられていたり、また、鍔部4c,5cにおけるリング形状の内径が、円筒状のシール部材13の外径よりも小さく設けられていると、シール部材13は下方において下部保持部材4,5に保持されることになり、上下方向における保持状態を一層確実に行うことができるようになる。 As described above, the lower holding members 4 and 5 are combined to form a ring shape, and the inner diameter of the ring shape is provided to be smaller than the outer diameter of the cylindrical seal member 13, or the collar portion. If the inner diameter of the ring shape in 4c and 5c is smaller than the outer diameter of the cylindrical seal member 13, the seal member 13 is held downward by the lower holding members 4 and 5, and is held in the vertical direction. It becomes possible to more reliably perform the holding state in.

本発明は、上記実施例で示したものに限られずに、本発明の目的達成に資する適宜の改変を施すことができるものである。 The present invention is not limited to those shown in the above examples, and can be appropriately modified to contribute to the achievement of the object of the present invention.

本発明は、エアサスペンションのエアバック下端部とダンパーとの連結部に装着され、この連結部を保持して密着固定状態を維持することができ、これによりエアサスペンションの耐久性や信頼性を向上することができるようにしたエアサスペンションのエア封止用プロテクタとして好適に利用することができる。 The present invention is attached to a connecting portion between the lower end of the airbag of the air suspension and the damper, and the connecting portion can be held to maintain a close contact and fixed state, thereby improving the durability and reliability of the air suspension. It can be suitably used as an air sealing protector for an air suspension that can be used.
