CYLINDRICAL VIBRATION DAMPER
Document Type and Number:
Japanese Patent JP2018159455
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cylindrical vibration damper having a new structure, which can set a larger spring ratio in axis perpendicular two directions, and which can achieve simplification of a fixing structure between an intermediate sleeve and an outer cylinder member.SOLUTION: In a cylindrical vibration damper 10, in an inner shaft member 12, a first outward protrusion part 22 and a second outward protrusion part 24 are provided protruding in a first axis perpendicular direction 21a and a second axis perpendicular direction 21b, the inner shaft member 12 and an intermediate sleeve 14 are connected by a body rubber elastic body 16, and an outer cylinder member 18 is fixed to the intermediate sleeve 14. On both sides in the first axis perpendicular direction 21a, inward protrusion parts 46 are provided at the intermediate sleeve 14, and the first outward protrusion part 22 and the intermediate sleeve 14 are connected by the body rubber elastic body 16. On the other hand, on both sides in the second axis perpendicular direction 21b, spaces 68 are provided around the second outward protrusion part 24, and also, the intermediate sleeve 14 is constituted by a pair of half-split cylindrical bodies 30a, 30b.SELECTED DRAWING: Figure 1
