摘要： A final drive assembly for transmitting torque from a drive source to an output device is provided. The final drive assembly includes a non-rotatable housing, a rotatable shaft defining an outer surface, a gear assembly, at least one bearing assembly, and a bushing. The gear assembly is configured to be couple to the drive source. The gear assembly is coupled to the housing and coupled to the shaft through a rotatable member. The rotatable member is configured to transmit torque from the drive source to the shaft and to provide relative radial movement between the shaft and the rotatable member. The bearing assembly is coupled to the housing and configured to rotatably support the rotatable member. The bushing is radially disposed between the rotatable member and the outer surface of the shaft. The bushing, which is configured to transmit substantially all of an external load exerted on the shaft to the rotatable member, is fixedly coupled to one of the rotatable member or the shaft.
