Abstract
A fluid-filled bushing with variable damping forces includes an inner tube, an outer tube, an elastomeric body joining the inner and outer tubes, a plurality of fluid chambers defined by the elastomeric body between the inner and outer tubes in circumferentially spaced relationship, a fluid passage for providing communication between the fluid chambers, a valve disposed in the inner tube for controlling fluid flow through the fluid passage, and a valve actuator for actuating the valve. The fluid passage includes a plurality of first passages defined in the inner tube and each communicating with one of the fluid chambers, and a plurality of second passages defined in the valve and communicable with the first fluid passages, respectively, the second fluid passages cooperating with the first fluid passages in varying cross-sectional areas thereof. A flange is provided on the inner tube at one axial end thereof for attachment to a vehicle frame, and a valve actuator is mounted on the flange remotely from the inner tube for actuating the valve.
