Vibration insulating assembly and method for making the same

Abstract

The present invention is directed to a vibration insulating assembly including a rubber vibration insulator and metallic members bonded thereto. In particular, the present invention relates to a method for manufacturing the same, by which the quality of the resulting assembly is improved by providing a high bonding strength between the vibration insulator and metallic members. Retainers are provided about the peripheries of the bonding surfaces of the rubber vibration insulator in order to restrict displacement and deformation of the rubber vibration insulator across the bonding surfaces or at the bonding interface with the metallic members and to facilitate its positioning. The presence of the retainers allows for the application of a predetermined pressure on the bonding surfaces to enhance the bonding strength while preventing an undesirable strain from forming in the bonding surface of the rubber vibration insulator. At least one and preferably a plurality of grains or recessed portions are preferably formed in the bonding surfaces of the rubber vibration insulator to be bonded to the metallic members. An adhesive, which is preferably solvent-free, is applied to these bonding surfaces to effect bonding.
