TUBULAR VIBRATION-DAMPING DEVICE USED FOR VIBRATION-DAMPING CONNECTING ROD, VIBRATION-DAMPING CONNECTING ROD USING THE SAME, AND METHOD OF MANUFACTURING VIBRATION-DAMPING CONNECTING ROD

摘要

Provided are a tubular vibration-damping device for a vibration-damping connecting rod, a vibration-damping connecting rod using the same and a method of manufacturing the vibration-damping connecting rod. The device including an inner shaft member and an outer tubular member being connected by a main rubber elastic body, the inner shaft member having a structure wherein first and second connecting members are inserted into a sleeve member bonded to the main rubber elastic body, the connecting members being axially overlapped with and spaced from each other to provide a rod-end insertion space communicated with outside via rod insertion holes that open through peripheral walls of the sleeve member and the outer tubular member, one end of a rod main body being inserted via the rod insertion holes into the rod-end insertion space and fixed to the first and second connecting members by a fastening member.

主权项

1. A tubular vibration-damping device for a vibration-damping connecting rod having a rod main body, comprising:
an inner shaft member configured to be mounted on the rod main body; an outer tubular member; and a main rubber elastic body elastically connecting the inner shaft member and the outer tubular member, wherein the inner shaft member comprises a sleeve member, a first connecting member and a second connecting member, the first and second connecting members being overlapped with each other in an axial direction and being inserted into the sleeve member, the main rubber elastic body is bonded to an outer peripheral face of the sleeve member, overlapping faces of the first and second connecting members in the axial direction are separated from each other so as to provide therebetween a rod-end insertion space, the rod-end insertion space is communicated with an outside via a rod insertion hole that opens through peripheral walls of the sleeve member and the outer tubular member, and the first and second connecting members are configured to be fixed on one end of the rod main body inserted into the rod-end insertion space via the rod insertion hole by a fastening member so that the first and second connecting members are abutted on the rod main body by the fastening member.
