Title:
FLUID SEALED TYPE CYLINDRICAL VIBRATION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018031393
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid sealed type cylindrical vibration control device having a new structure capable of providing not only a vibration-proof effect against a vibration in a direction perpendicular to a shaft but also effectively attaining a vibration-proof effect against vibration in an axial direction.SOLUTION: This invention relates to a fluid sealed type cylindrical vibration control device 10 that is constituted in such a way that an inner shaft member 12 and an outer cylindrical member 14 are resiliently connected by a main body rubber elastic body 16, a pair of first liquid chambers 38, 38 where a part of wall portion is constituted by the main body rubber elastic body 16 are formed and arranged in a radial direction and at the same time an orifice passage 48 communicating these first liquid chambers 38, 38 is formed in a peripheral direction at an outer peripheral portion, a rubber wall 50 is arranged outside in an axial direction of the main body rubber elastic body 16, an annular second liquid chamber 74 is formed between the main body rubber elastic body 16 and a rubber wall 50, incompressible fluid sealed in the second liquid chamber 74 is higher viscous fluid than the incompressible fluid sealed in the first liquid chambers 38, 38 and at the same time a narrowed flow passage 78 opened in an axial direction is formed in the second liquid chamber 74.SELECTED DRAWING: Figure 1
