VIBRATION CONTROL DEVICE

Japanese Patent JP2018115718

A

PROBLEM TO BE SOLVED: To provide a vibration control device which achieves improvement of features for vibration having a relatively small frequency and a relatively large amplitude and vibration having a relatively large frequency and a relatively small amplitude.SOLUTION: A vibration control device 1 includes an outer cylinder 11, an inner member 12, an elastic body 13, a partition member 17, an intermediate cylinder 31, and a partition member 32. The elastic body connects the outer cylinder with the inner member. The partition member partitions a liquid chamber 14 in the outer cylinder into a main liquid chamber 15 and a sub liquid chamber 16. An orifice passage 21 is formed at the partition member. The intermediate cylinder 31 is disposed between the outer cylinder and the inner member and connected to the elastic body. The partition member is connected with the intermediate cylinder and divides the main liquid chamber into a first main liquid chamber 15a and a second main liquid chamber 15b. A housing chamber 37, a first communication hole 37a, and a second communication hole 37b are formed in the partition member. A movable member 36 which may be displaced or deformed according to a pressure difference between the first main liquid chamber and the second main liquid chamber is housed in the housing chamber.SELECTED DRAWING: Figure 1
