Title
(EN) SUSPENSION CONTROL DEVICE AND ELECTROVISCOUS DAMPER
(FR) DISPOSITIF DE COMMANDE DE SUSPENSION ET AMORTISSEUR ÉLECTRO-VISQUEUX
(JA) サスペンション制御装置並びに電気粘性ダンパ
Abstract
(EN)
This suspension control device is characterized by having: an electroviscous damper; a high voltage output circuit; a connection part; and a control unit. The electroviscous damper is provided with a cylinder in which an electroviscous fluid is sealed, a piston, a piston rod, and a positive electrode that is provided to a part where flowing of the electroviscous fluid is generated through sliding of the piston in the cylinder and that applies a voltage to the electroviscous fluid. The connection part is provided with an electrode connection section for connecting the high voltage output circuit and the positive electrode, and a ground connection section for connecting the cylinder and ground. A resistance member which provides a load resistance value of the electroviscous fluid within the normal temperature range of the electroviscous damper is provided between the electrode connection section and the ground connection section.

L'invention concerne un dispositif de commande de suspension se caractérisant en ce qu'il comprend : un amortisseur électro-visqueux ; un circuit de sortie haute tension ; une partie raccordement ; et une unité de commande. L'amortisseur électro-visqueux est pourvu d'un cylindre dans lequel est contenu hermétique un fluide électro-visqueux, d'un piston, d'une tige de piston et d'une électrode positive disposée sur une partie dans laquelle l'écoulement du fluide électro-visqueux est généré par coulissement du piston dans le cylindre, et qui applique une tension sur le fluide électro-visqueux. La partie raccordement comporte une partie raccordement d'électrode destinée à raccorder le circuit de sortie haute tension et l'électrode positive, et une partie raccordement à la terre destinée à raccorder le cylindre et la terre. Un élément de résistance qui fournit une valeur de résistance de charge du fluide électro-visqueux dans la plage de températures normales de l'amortisseur électro-visqueux est disposé entre la partie raccordement d'électrode et la partie raccordement à la terre.
