Title:
TUBULAR VIBRATION ISOLATION DEVICE
Document Type and Number:
Japanese Patent JP2021017969
Kind Code:
A
Abstract:
To provide a tubular vibration isolation device having a novel structure which can achieve a degree of freedom of the tuning of a spring characteristic or the like while sufficiently securing the durability of a main body rubber elastic body.SOLUTION: In a tubular vibration isolation device 10 in which an inner shaft member 12 and an outer cylinder member 14 are connected to each other via a main body rubber elastic body 16, a hollow part 24 opened at an end face in an axial direction, and extending in the axial direction toward a plate-shaped part 18 of the inner shaft member 12 on an external peripheral face of the inner shaft member 12 is formed at the main body rubber elastic body 16. A deformation control face 34 protruding on the external peripheral face is formed at the inner shaft member 12. An overlapped region 36 expanding along an inner face 26 of the hollow part 24, and a release region 38 gradually separating from the inner face 26 of the hollow part 24 toward an opening side of the hollow part 24 from the overlapped region 36 are arranged at the deformation control face 34. An abutment region of the main body rubber elastic body 16 abutting on the deformation control face 34 is expanded toward the release region 38 from the overlapped region 36 following an increase of an input load.SELECTED DRAWING: Figure 1
