Title:
VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/002781
Kind Code:
A1
Abstract:
A vibration-damping device (10) is provided with: a tube-shaped first mounting member (11) connected to one of a vibration generation section and a vibration receiving section; a second mounting member (12) connected to the other of the vibration generation section and the vibration receiving section; an elastic body (13) for connecting both the mounting members; and a partition member (15) for partitioning a liquid chamber (16) within the first mounting member (11) into a primary liquid chamber (17), in which the elastic body (13) serves as a part of the wall surface of the primary liquid chamber (17), and into a secondary liquid chamber (18). The partition member (15) is provided with: a receiving chamber (47) connecting to both the primary liquid chamber (17) and the secondary liquid chamber (18) through connection holes (46A, 46B) open in the axial direction; an elastically deformable membrane (48) received in the receiving chamber (47) and exposed to both the primary liquid chamber (17) and the secondary liquid chamber (18) through the connection holes (46A, 46B); and restriction sections (51A, 51B) located on the outside of the connection holes (46A, 46B) in the axial direction and overlapping the membrane (48) in the axial direction through the connection holes (46A, 46B). In the vibration-damping device (10), the performance of the membrane (48) is maintained for a long period of time.
