Active decoupler hydraulic mount

A hydraulic mount for an operating component of a vehicle comprising:

• first and second mounting members;
• a body connected to one of the mounting members and a base connected to the other of the mounting members;
• a partition interposed between said body and said base and defining a cavity, said partition including an orifice track formed therein for transferring fluid between a fluid pumping chamber and a fluid reservoir of said mount;
• and
• a decoupler member supported in said cavity and in fluid communication with at least one of said pumping chamber and said reservoir, said decoupler member being formed of an electroactive polymer, and adapted to be operably connected to a source of electric potential for selectively changing the configuration of said decoupler member to vary the dynamic stiffness of said mount.

• a body connected to one of the mounting members and a base connected to the other of the mounting members;
• a partition interposed between said body and said base and defining a cavity, said partition comprises an orifice plate assembly including a first orifice plate and having a plurality of openings formed therein for providing fluid communication between said pumping chamber and said cavity and a second orifice plate including a plurality of openings therein for providing fluid communication between said reservoir and said cavity;
• a decoupler member supported in said cavity and in fluid communication with said pumping chamber and said reservoir, said decoupler member being formed of an electroactive polymer, and adapted to be operably connected to a source of electric potential for selectively changing the configuration of said decoupler member to vary the dynamic stiffness of said mount;
• conductor means connected to respective electrodes of said decoupler member;
• and
• a controller operably connected to said conductor means and a source of electric power for imposing an electric field on said decoupler member at a selected frequency to effect deflection of said decoupler member in such a way as to modify the dynamic stiffness of said mount.
