Abstract

A unified frame/body assembly is provided for a vehicle, such as a tow tractor. The reinforced center core of the tractor has a pair of longitudinal box-like body sections. Each body section includes a box beam with an integral extension panel. Substantially planar fenders structurally bridge between and connect the body sections to a wing at each end of a bumper member. The extension panel, fender and wing of the bumper form a substantially rigid quarter panel providing support for the vehicle through the suspension means of the vehicle. A pair of cantilever arms mount the suspension, preferably leaf springs, by attachment to the box beams with the distal end of the springs being connected to a mounting plate extending along the bottom of the bumper member. The quarter panel provides structural support between the body sections and the bumper member so as to provide an open space within the tractor that is substantially free of obstructions so as to allow a lowered profile and increased turning radius of the wheels of the tractor. The fender includes an inwardly extending lip along the upper margin so as to increase rigidity. The lower margin of the fender includes tabs and weldments are provided around the tabs to form the quarter panel. Preferably, strong structural material, such as 0.5' steel is used to provide the requisite support strength and for added weight to the tractor for increased friction to allow efficient handling of heavy loads.
