Document Type and Number:
Japanese Patent JP6941524
Kind Code:
B2
Abstract:
An active damper is disclosed which includes: an elastic support body; a first wall section provided at the elastic support body and defines a first liquid chamber; a second wall section provided on an opposite side and defines a second liquid chamber; a partition wall section which separates the first liquid chamber from the second liquid chamber; an orifice in the partition wall section for communication between the first and second liquid chambers; and a damping unit to attenuate the vibrations transmitted from a vibrating source to the vibration-receiving part. The damping unit includes: a coil to generate a magnetic field according to a current supplied; magnetic members forming a closed magnetic circuit for the magnetic field; and a magneto-viscoelastic elastomer having a viscoelasticity changes depending on the magnetic field. At least one of the first and second wall sections, and the partition wall section has the damping unit.
