A torque transfer case includes an output shaft angled relative to an input shaft by the use of a constant velocity (CV) universal joint. The CV joint is contained within a hollow drive sprocket rotatably supported within a housing by a pair of spaced apart, different sized bearing assemblies, and is coupled to input shaft via a drive chain. The drive sprocket is provided with a cylindrical opening at one end thereof and a smaller cylindrical opening at an opposite end thereof. The different sized openings produce a differential pressure across the openings when the sprocket is rotated, thus causing oil contained in the housing to flow through the sprocket and lubricate the CV joint. The output shaft has one end which extends into the one cylindrical opening of the drive sprocket and is coupled to the CV joint, and an opposite end which is rotatably supported within the housing by a single bearing unit. The torque transfer case can be a four wheel drive transfer case and include a differential for dividing torque between a rear output shaft and an angled front output shaft. |
