Abstract
A compact, trailing, auxiliary axle system is attached to a truck for carrying additional weight and distributing the weight of the truck over a greater number of axles and a greater maximum total distance of distribution of those axles. The apparatus is attached high, and may be secured to the body of a truck, such as a refuse truck, reducing the total length of extension from the rear of the truck, yet pivoting from a comparatively high position for easy stowage above the bubble or bulkhead protruding from the tailgate of a truck. Hydraulic actuation relies on pulling, during deployment, providing improved resistance to buckling, protection from road damage, with short coupling for improved strength of booms, hydraulics, and cross members. Conduits may carry control and power through the frame of the assembly, and conventional suspension components may be used. A "broken" frame design provides easy attachment for suspension systems, length within legal regulatory limits, leverage against the load presented by the truck, durable structures, and straightforward manufacturing processes with rapid alignment and assembly. The overall envelope is only minimally affected for the truck b…
