Abstract
A final drive system for a machine includes a stationary side housing in which a planetary gear assembly and an elongated brake hub member are disposed. The planetary gear assembly includes a ring gear disposed within the stationary side housing; a planetary gear carrier rotatably supported by the stationary side housing; and multiple planet gears that are disposed in mesh with the ring gear. The planetary gear assembly further includes a sun gear disposed in mesh with the planet gears to rotatably drive the planet gears. The elongated brake hub member axially extends from the sun gear and defines a set of internal and external splines that are located distally away from the integrally formed sun gear. The set of internal splines and the set of external splines are configured to mesh with a set of external splines from an axle shaft and a brake pack of the machine respectively.
