摘要： A triple reduction final drive assembly for a work vehicle comprises a first input spur gear, a first cluster gear, a second cluster gear and an output spur gear that are located in a housing. The output spur gear is provided with an output shaft which is rotatively mounted on bearings in the housing. The first cluster gear rotates on annular bearings that encircle a portion of the output shaft. The first cluster gear and output spur gear define coaxial drive axes. The second cluster gear is also rotatively mounted on bearings located in the housing. The second cluster gear defines a drive axis that is parallel to and spaced apart from the drive axes of the first cluster gear and the output spur gear. The first cluster gear is provided with a first toothed surface and a second toothed surface. The first toothed surface of the first cluster gear engages the input spur gear thereby defining the first gear reduction. The second cluster gear is also provided with a first toothed surface and a second toothed surface. The first toothed surface of the second cluster gear engages the second toothed surface of the first cluster gear thereby defining the second gear reduction. The second toothed surface of the second cluster gear engages the output spur gear thereby defining the third gear reduction.
