Embodiment Construction

[0036] Referring to the drawings, there is shown a constant velocity joint for a transfer case according to the invention. Although the present invention will be described in terms of a transfer case for a motor vehicle, it should be recognized that other applications, such as gearboxes for marine vessels, are also considered to be within the scope of the present invention. The transfer case is preferably used in an all-wheel drive or four-wheel drive system, but it should be appreciated that it could be used in any known motor vehicle system. In fact, it should also be pointed out that the transfer case can be applied to a motor vehicle system driven only by the front wheels or only by the rear wheels.

[0037] The transfer case typically receives power from the vehicle engine through a transmission on the input shaft. When the input shaft rotates, the rear output shaft and the front output shaft also rotate because the two output shafts are rotatably connected to the rear d...

Abstract

A torque transfer device, such as a transfer case for a motor vehicle, having a constant velocity joint integrated therewith is disclosed. In one embodiment, the constant velocity joint includes an outer race rotatably mounted within the torque transfer device and an inner race positioned within the outer race and operatively connected to the outer race by one or more torque transmitting balls. The torque transfer device further includes a drive mechanism that is connected to the outer race of the constant velocity joint, wherein the drive mechanism transfers torque received from an input shaft to the outer race of the constant velocity joint such that the outer race drives the inner race. The torque transfer device further includes an output shaft that is rotatably connected to the inner race.
