緩衝器およびこれを用いた車両
Document Type and Number:
Japanese Patent JP6078635
Kind Code:
B2
Abstract:
A minimum length-side property in which an extension-side damping coefficient signifies a hard state in a range (Aa0) where the piston rod enters further inside the cylinder than a minimum length-side predetermined position (Sa1), and a maximum length-side property in which the extension-side damping coefficient signifies a soft state in a range (Aa4) where the piston rod extends further outside the cylinder than a maximum length-side predetermined position (Sa4) are included. An extension-side damping force property between the minimum length-side predetermined position (Sa1) and the maximum length-side predetermined position (Sa4) includes a part (Sa1 to Sa2, Sa3 to Sa4) in which a damping coefficient change rate with respect to a stroke of the piston rod is large and a part (Sa2 to Sa3) in which the damping coefficient change rate is small. At least when the piston rod strokes to the extension side from the minimum length-side predetermined position (Sa1), the damping coefficient change rate is allowed to be large.
