Synchronizer ring for device for sunchronously engaging in transmission

Abstract

Abstract PURPOSE:To reduce the nosie of a synchronizer ring inexpensively and lightly for a device for synchronously engaging gears in a transmission by forming integrally a ring body of thick shape of resin material on the outer periphery of an annular antifrictional metallic member forming a conical slide surface portion. CONSTITUTION:The conical slide surface portion of a synchronizer ring 12 is constructed by a thin hollow conical metallic annular member 22 of antifrictional material such as brass alloy, bronze allow or the like with suitable rough or rugged surface formed on the outer peripheral surface 23 of the member 22 and with threaded channel 24 formed on the inner peripheral surface of the slide surface 20. A thick ring member 25 is integrally formed by resin meterial such as asbestos- contained phenol resin on the outer periphery of the annular member 22 forming the conical slide surface portion. The resin material material includes, for example, additionally ethylene tetrafluoride, ethylene trifluoride chloride, glass fabric-contained polyester resin or the like as gear material.
