Schwingungsdämpfer mit einem Element aus Polyamidharz, welches mit einer elastischen Schicht überzogen ist und Herstellverfahren hierfür

摘要

A vibration damper of composite type including a vulcanized-rubber body (8) formed of a vulcanized rubber material and a polyamide-resin member (4) formed of a polyamide resin material, wherein the vulcanized-rubber body and the polyamide-resin member are integrally bonded together, and the exposed surface of at least the polyamide-resin member (4) is covered by a coating layer (20) formed of an elastic material with a predetermined thickness. Also disclosed in a method suitable for producing the vibration damper, wherein a solution of an unvulcanized rubber material or a thermoplastic elastomer is applied to the exposed surface of at least the polyamide-resin member, and is subjected to a vulcanizing or drying operation to form the coating layer.
