Abstract
A mounting structure disposed between a body and a power unit of a vehicle for mounting of the power unit on the body, so as to effect vibration damping and isolation under the control of a control device, including: an elastic body connected to one of the body and the power unit of the vehicle, and partially defining a pressure-receiving chamber filled with an incompressible fluid; an elastic member partially defining an equilibrium chamber filled with the fluid and communicating with the pressure-receiving chamber, so as to permit a change in a volume of the pressure-receiving chamber; a movable member disposed between the pressure-receiving and equilibrium chambers, and exposed to the pressure-receiving and equilibrium chambers, the movable member being movable over a predetermined maximum distance in opposite directions parallel to a direction in which the mounting structure receives vibrations; an elastic holder for flexibly supporting the movable member such that the movable member is movable in the opposite directions; a guide for guiding the movable member in the opposite directions; and a drive device connected to the control device, for reciprocating the movable member, over a controlled operating stroke and at a controlled frequency.
