Description
そこで、本発明は、全体に小型化できて、簡易に構成できるサスペンション装置を提供することを課題とする。
<実施形態1>
図1は、本発明の一実施形態であるサスペンション装置の断面図である。以下では、サスペンション装置1の図1における右側の先端部側を先端側と呼ぶことがある。また、サスペンション装置1の図1における左側を後方側と呼ぶことがある。
サスペンション装置1は液圧式ダンパ3を備えている。液圧式ダンパ3は、ロッド11、ピストン12、バルブ13,14などから構成されている。液圧式ダンパ3はコンベンショナルなサスペンションとして機能する。すなわち、サスペンション装置1の外側筐体である外筒4の内側には内筒5が収納されている。内筒5の内部には、内筒5と同軸芯のロッド11が収納されている。ロッド11は内筒5内を内筒5の長手方向(図1の左右方向)に移動可能である。ロッド11の長手方向先端側(右側)にはピストン12が設けられている。ピストン12はその外周面が内筒5の内周面に沿って移動する。
図3A、図3Bは、実施形態1にかかるサスペンション装置の作用を説明するサスペンション装置の概念図である。図3Aに示すように、ピストン12が内筒中央部32の区間に存在する場合は、ピストン12は内筒5の中央部に位置している。この場合に、バルブ13の位置で内筒5の径方向には、バルブ13と溝31が位置している。流体は矢印で示すように溝31を通過するので、液圧式ダンパ3の減衰力は非常に小さくなる。そこで、ピストン12が内筒中央部32の区間に存在する場合は、電動ダンパ8を駆動する。この内筒中央部32の区間は最も頻繁にピストン12が通過する区間である。
また、内筒5に溝31を形成するだけでよいため、サスペンション装置1を全体に小型化できて、簡易に構成することができる。
さらに、磁石21、コイル23を設けている部位を利用して、磁石内流路22(オリフィス)、コイル内通路24(オリフィス)を設けることにより、電動ダンパ8全体の外形を細くできる。
本実施形態2では、実施形態1と異なる点を中心に説明し、共通事項は同じ部材に同じ符号を用いて省略する。
図3Aに示すように、ピストン12が内筒中央部32の区間に存在する場合は、ピストン12は内筒5の中央部に位置している。この場合に、バルブ13の位置で内筒5の径方向には、バルブ13と拡径部41の拡径した部分が位置している。流体は矢印で示すように拡径部41の拡径した部分を通過するので、液圧式ダンパ3の減衰力は非常に小さくなる。そこで、ピストン12が内筒中央部32の区間に存在する場合は、電動ダンパ8を駆動する。この内筒中央部32の区間は最も頻繁にピストン12が通過する区間である。
また、内筒5に溝31を形成するだけでよいため、サスペンション装置1を全体に小型化できて、簡易に構成することができる。
磁石21、コイル23を設けている部位を利用して、磁石内流路22(オリフィス)、コイル内通路24(オリフィス)を設けることにより、電動ダンパ8全体の外形を細くできる。
なお、内筒中央部32に前記のような連通路を設ける手段としては、第1実施形態の溝31の形成や、第2実施形態の拡径部41の形成に限定されず、他の手段を用いてもよい。
