ABSTRACT:
A fluid-filled vibroisolating device comprises a joint member adapted to be joined to a vibrating body such as an engine. A support member is adapted to be supported on a supporting body such as a vehicle frame and defining an expandable and contractible auxiliary fluid chamber filled with a fluid. An elastomeric member interconnects the joint and support members and is disposed in a vibrating direction in which the vibrating body vibrates. The elastomeric member, the joint member, and the support member jointly define an expandable and contractible main fluid chamber filled with a fluid. A partition is mounted in the support member and separates the main and auxiliary fluid chambers from each other. The partition has flow regulators for regulating the flow of the fluid between the main and auxiliary fluid chamber. A reinforcing member is integrally formed with the elastomeric member for preventing the elastomeric member from being collapsed. By selecting various parameters of the device to meet a predetermined equation, and providing as the flow regulating mechanism an orifice between the main and auxiliary fluid chambers for allowing the fluid to flow or resonate, and also a movable plate movable dependent on the difference between the fluid pressures in the main and auxiliary fluid chambers, the damping capability of the fluid-filled vibroisolating device is improved and the dynamic spring constant thereof is uniformly lowered in a wide range of frequencies.
