Abstract
An axle driving apparatus includes a first axle driving unit (18L) having a housing (40) and a single axle (20L). An enlarged region is defined by the housing (40), with the enlarged region extending substantially perpendicular to the longitudinal axis of the single axle (20L). A hydraulic stepless speed change assembly is disposed in the enlarged region. The speed change assembly includes a hydraulic pump (52) having an input shaft (21) projecting from the enlarged region and includes a hydraulic motor (55) including an output shaft (74) drivingly connected to the single axle (20L). A second axle driving unit (18R) having similar construction is adjacently disposed to the first axle driving unit (18L). However, the second axle driving unit (18R) features a single axle (20R) being disposed on the opposite side of the single axle (20L) of the first axle driving unit (18L).
