INSULATOR DEVICE FOR SUSPENSION OF VEHICLES

An insulator device includes a middle cup including an exterior wall disposed at the center of the mounting hole of the main panel and joined to the rubber member, a horizontal wall of which an upper portion of the strut rod is held in the middle of the interior and a vertical wall spaced inwardly of the exterior wall, an upper cup including an upper plate covering the upper part of the rubber member and an upper wall formed between the exterior wall and the vertical wall to form an upper hydraulic chamber, and the upper cup of which a first opening is formed thereto, a first elastic member disposed within the upper hydraulic chamber, and a control unit that selectively supplies hydraulic pressure to the upper hydraulic chamber through the first opening.
