Abstract
A tandem axle assembly capable of accommodating variations in driveline length is provided. The tandem axle assembly includes forward and rear axle assemblies each having a wheel differential with the forward axle assembly further including an inter-axle differential for dividing power between the two wheel differentials. A male-female slip connection is formed between two members at one or more of the following intersections: the connection between a power input shaft driving the inter-axle differential and a power transmission shaft for transferring power from a vehicle driveshaft to the power input shaft; the connection between an output shaft driven by the inter-axle differential and an output yoke of an intermediate drive shaft assembly extending between the forward and rear axle assemblies; and the connection between an input yoke of the intermediate drive shaft assembly and a pinion shaft in the rear axle assembly drivingly coupled to the rear wheel differential.
