Title
(EN) VARIABLE STIFFNESS STABILIZER DEVICE
(FR) DISPOSITIF STABILISATEUR DE RIGIDITÉ VARIABLE
(JA) 可変剛性スタビライザ装置
Abstract
(EN)
A variable stiffness stabilizer device (1) has a stabilizer bar (2) and actuators (3). The stabilizer bar (2) has a torsion bar (4) extending in the lateral direction (X1) of a vehicle and arms (6) connected through bent parts (5) to the ends (4a, 4b) of the torsion bar (4) and bend and deformed according to the strokes of wheel support members (11). Variable bending stiffness parts (13; 130) of the arms (6) are rotatable about the axes (C1) of the arms (6), so that the bending stiffness of the arms (6) can be changed according to their rotational positions. The actuators (3) rotate the variable bending stiffness parts (13; 130) about the axes (C1) to adjust the rotational positions of the variable bending stiffness parts (13; 130).
(FR)
L'invention concerne un dispositif stabilisateur de rigidité variable (1) ayant une barre de stabilisateur (2) et des actionneurs (3). La barre de stabilisateur (2) comprend une barre de torsion (4) s'étendant dans la direction latérale (X1) d'un véhicule et des bras (6) reliés par l'intermédiaire de parties courbées (5) aux extrémités (4a, 4b) de la barre de torsion (4) et fléchis et déformés selon les courses d'éléments de support de roue (11). Des parties de rigidité à la flexion variable (13 ; 130) des bras (6) sont aptes à tourner autour des axes (C1) des bras (6), de telle sorte que la rigidité à la flexion des bras (6) peut être amenée à changer selon leurs positions en rotation. Les actionneurs (3) entraînent en rotation les parties de rigidité à la flexion variable (13 ; 130) autour des axes (C1) pour ajuster les positions en rotation des pièces de rigidité à la flexion variable (13 ; 130).
(JA)
 可変剛性スタビライザ装置(1) が、スタビライザバー(2) とアクチュエータ(3) とを備える。スタビライザバー(2) は、車両の左右方向(X1)に延びるトーションバー(4) と、トーションバー(4) の端部(4a,4b) に屈曲部(5) を介して接続され車輪支持部材(11)のストロークに応じて曲げ変形するアーム(6) とを含む。アーム(6) の曲げ剛性可変部(13;130)は、アーム(6) の軸線(C1)の回りに回転可能に設けられ、その回転位置に応じてアーム(6) の曲げ剛性を変更可能である。アクチュエータ(3) が、曲げ剛性可変部(13;130)を上記軸線(C1)の回りに回転駆動し、曲げ剛性可変部(13;130)の回転位置を調整する。
