Patent ID: 7926823

Claim:
A system for damping vibratory forces applied to a vehicle, comprising; at least one mount including a first rigid member connectable to the body of a vehicle, a second rigid body connectable to a wheel suspension system of said body and a body of elastomeric material interconnecting said members having a pair of chambers spaced along an x-axis, provided with a damping liquid, and means providing a restricted passageway between said chambers; actuating means operatively connected to said elastomeric body for applying vibratory forces on the damping liquid of at least one of said chambers for counteracting vibrating forces applied to said vehicle; means for detecting said vibratory forces applied to said vehicle; and processing means responsive to detected vibratory forces applied to said vehicle operatively connected to said actuating means to vary the damping effect of said mount, wherein said actuating means includes a piezoelectric device.
