Abstract:
(EN) In order to make it possible to apply a greater damping force than with conventional suspensions while also decreasing thickness, a damper (60) is provided toward the side of an upper frame (10), which is a main vibration member supported at the tops of a front link (30) and a rear link (40) in a frame linking mechanism, so as to serve as an accessory vibration means that generates vibrations with a behavior different from the vibrations in the upper frame (10) which are generated by the rotational movements of the front link (30) and the rear link (40). When the upper frame vibrates due to input vibrations, the damper (60) exhibits a different vibrational behavior; thus, the energy of the input vibrations is not only dispersed as the vibrational energy of the upper frame (10) and the thermal energy generated by the expansions and contraction of the damper (60), but is also consumed as the energy that induces the vibration of the damper (60) itself, which is provided as a vibrating member. As a result of having such a structure, the damper (60) improves the basic performance of the suspension in terms of the vibration absorption characteristics and shock absorption characteristics thereof.
(FR) La présente invention a trait à une suspension. Afin de permettre l'application d'une force d'amortissement plus importante qu'avec des suspensions classiques tout en réduisant également l'épaisseur, un amortisseur (60) est disposé en direction du côté d'un châssis supérieur (10), qui est un élément de vibration principal tenu au niveau des parties supérieures d'une liaison avant (30) et d'une liaison arrière (40) dans un mécanisme de liaison de châssis, de façon à servir de moyen de vibration accessoire qui génère des vibrations au comportement différent des vibrations dans le châssis supérieur (10) qui sont générées par les mouvements de rotation de la liaison avant (30) et de la liaison arrière (40). Lorsque le châssis supérieur vibre sous l'effet des vibrations introduites, l'amortisseur (60) manifeste un comportement de vibration différent ; ainsi, l'énergie des vibrations introduites est non seulement dispersée à titre d'énergie de vibration du châssis supérieur (10) et d'énergie thermique générée par les expansions et la contraction de l'amortisseur (60), mais est également consommée à titre d'énergie qui provoque la vibration de l'amortisseur (60) lui-même, qui se présente sous la forme d'un élément vibrant. En raison d'une telle structure, l'amortisseur (60) améliore la performance de base de la suspension en termes de caractéristiques d'absorption des vibrations et de caractéristiques d'absorption des chocs correspondantes.
(JA) 従来よりも高い減衰力を作用させることができ、さらなる薄型化を図る。 ダンパー(60)が、フレーム用リンク機構の前部リンク(30)及び後部リンク(40)の上部に支持される主振動体である上部フレーム(10)側に、前部リンク(30)及び後部リンク(40)の回転運動によって生じる上部フレーム(10)の振動とは異なる挙動の振動を生じる副振動体となるように設けられている。入力振動によって上部フレームが振動した際、ダンパー(60)は、異なる振動挙動を示すため、入力振動のエネルギーが、上部フレーム(10)の振動エネルギー、ダンパー(60)の伸縮によって生じる熱エネルギーに分散されるだけでなく、振動体として設けられたダンパー(60)自体を振動させるエネルギーとしても消費される。ダンパー(60)のこのような配置構造は、サスペンションの有する振動吸収特性、衝撃吸収特性の基本的性能を向上させる。
