<p>An axle beam has a pair of side plates individually secured to the ends of a pair of vertically spaced upper and lower plates and a vertically disposed plate secured to the forward edges of the upper and lower plate. A pair of wheel drive gears are individually journalled on a pair of spindles individually secured to the outer surfaces of the side plates with the spindles having a horizontal axis extending therethrough. A differential disposed within the axle beam is secured to one of the plates and has a pair of jackshafts extending outwardly from its opposite sides. Each jackshaft extends through an aperture formed in the side plate and has a gear formed on its distal end mating with the respective wheel drive gear. The jackshafts and apertures are radially offset from the horizontal axis a predetermined distance as determined by the mating relation between the gears such that said apertures are located in one of a plurality of positions which are disposed on a pair of diametrically opposite arcs of a circle having the horizontal axis of the spindle as its center and the predetermined distance as its radius, with one of the arcs being disposed forwardly of the horizontal axis.</p> |
