Abstract
A selectively deployable auxiliary wheel system for a refuse collecting vehicle includes a pair of spaced tag axle assemblies. The system can be used with any type of refuse vehicle and is designed to mount either to the truck or the tailgate. Each assembly includes a suspension system including an axle mounting lever carried by a transverse tag pivot shaft and carrying a stub axle and a wheel on the stub axle. A fluid operated tag axle deployment system is used for applying forces to control the deployment of the tag axle between a ground engaging vehicle supporting position and a stowed position. In one embodiment, the system uses a pair of fixed pneumatic springs and a pair of torque arm levers to pivot the axle mounting lever such that the displacement of one of the levers relative to stationary mounting supports raises or lowers the axle mounting lever. In another embodiment, the displacement of a single torque arm lever relative to a stationary mounting support by a single, double-acting hydraulic cylinder device controls the deployment of the tag axle between a ground engaging, vehicle supporting position and a stowed position.
