A tandem axle assembly is provided. The tandem axle assembly includes a forward axle assembly (12) and a rear axle assembly (14) and an intermediate drive shaft assembly (16) extending between the two axle assemblies. The forward and rear axle assemblies both includes a pinion gear (98) rotating responsive to an inter-axle differential (22) and a ring gear (100) in mesh with the pinion gear. The forward pinion gear is offset from the rear ring gear by a first predetermined distance (H1) while the rear pinion gear is offset from the rear ring gear by a second predetermined distance (H2). The second predetermined distance is greater then zero, bit is less than the first predetermined distance. The variation in offsets enables both equal working angles (21,22) in the intermediate drive shaft assembly and a reduction in those angles as compared to convertional tandem axle assemblies. Further, the variation in offset results in stronger and quieter gearing. |
