ABSTRACT:
A drive assembly (20) has a planetary gear assembly (27), driven member (22), and first housing element (28). The assembly (20) is, for example, part of a final drive (12) of a work vehicle (10) or pulley drive for a material handling system. A first bearing element (30) supports the driven member (22) in rotatable relationship relative to the housing element (28). A second bearing element (32) supports the housing element (28) in rotatable relationship relative to the gear assembly (27). On the vehicle (10), gear reduction taken inside of a tandem housing (14) has heretofore resulted in an overturning reaction force on the housing (14) which creates unequal wheel loads. In the drive assembly (20), the first and second bearing elements (30,32) are positioned between the driven member (22) and housing element (28) and a ring gear element (40) of the gear assembly (27) and the housing element (28), respectively, to provide gear reduction substantially within and to substantially prevent the reaction force on the tandem housing (14).
