Abstract
An air-isolated fifth wheel system for use in connecting a trailer to a semi-tractor in a manner to isolate vibrational input of the trailer to the fifth wheel from being transferred to the semi-tractor. An inflatable air bag is operably disposed in a centered location beneath the fifth wheel support plate to eliminate vertical fifth wheel load from being transferred to the semi-tractor. The system is light weight and can easily be included into existing fifth wheel assemblies without significant alteration to the chassis of the semi-tractor.
