Abstract
Official abstract text for this publication.
A drive assembly for motor graders is provided, which includes a differential gear arrangement and at least one final drive arrangement. The differential gear arrangement includes a differential housing and at least one differential output shaft. The final drive arrangement is driven by differential housing and the differential output shaft. The final drive arrangement includes a primary planetary gear assembly, a secondary planetary gear assembly, and a clutch. The primary planetary gear assembly includes a first sun gear powered by output shaft, two first planetary gears, a first ring gear positioned stationary, and a first planetary carrier fixed to a wheel drive mechanism. The secondary planetary gear assembly includes second sun gear powered by the differential housing, second planetary gear, second ring gear, and second planetary carrier fixed to the first planetary carrier. The clutch partially engages and disengages with the second ring gear, to correspondingly partially restrict and release the second ring gear.
First claim
Opening claim text (preview).
What is claimed is: 1 . A drive assembly for a machine, the drive assembly comprising: a differential gear arrangement including a differential housing and at least one output shaft; and at least one final drive arrangement configured to be selectively driven by the differential housing and the at least one differential output shaft, the at least one tandem drive including: a primary planetary gear assembly including a first sun gear, at least one first planetary gear, a first ring gear, and a first planetary carrier, wherein one of the at least one first planetary gear and the first ring gear is stationary, the first sun gear is powered by the at least one differential output shaft of the differential gear arrangement, and the first planetary carrier is fixedly connected to a wheel drive mechanism; a secondary planetary gear assembly including a second sun gear, at least one second planetary gear, a second ring gear, and a second planetary carrier, wherein the second sun gear is connected to and powered by the differential housing of the differential gear arrangement, wherein the second planetary carrier is fixedly connected to the first planetary carrier; and a clutch adapted to engage and disengage the second ring gear, to correspondingly restrict and release the second ring gear of the secondary planetary gear assembly.
