VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2017044220
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress high resilience when vibrations are inputted.SOLUTION: A vibration control device 10 includes: a cylindrical outer attaching member 11 and an inner attaching member 12; a pair of body rubbers 13 and 14 which couple the outer attaching member 11 and the inner attaching member 12, and are disposed at an interval in an axial direction along a center axis O of the outer attaching member 11; a partitioning member 15 which couples the outer attaching member 11 and the inner attaching member 12, and partitions a liquid chamber 25 between the pair of body rubbers 13 and 14, into a first liquid chamber 26 and a second liquid chamber 27 in an axial direction; and a diaphragm 16 which configures a part of a wall surface defining an auxiliary liquid chamber 32. The partitioning member 15 is equipped with an annular rigid body portion 28 which is formed with a first limit passage 33 communicating the first liquid chamber 26 and the auxiliary liquid chamber 32 and a second limit passage 34 communicating the second liquid chamber 27 and the auxiliary liquid chamber 32; and an annular elastic portion 29 ranging to the rigid body portion 28 in a diametrical direction intersecting the center axis O.SELECTED DRAWING: Figure 1
