摘要： 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).

摘要： An axle driving system which houses in a housing (1, 2) thereof a hydrostatic transmission, axles (7), and a driving gear train for connecting otput means of the hydraulic transmission and axles, so as to transmit power from a driving source to the hydrostatic transmission and to change the speed, thereby driving the axles. A first chamber (R1) therein contains the hydrostatic transmission and a second chamber (R2) therein contains the driving gear train. Both the first and second chambers are independent of each other so as to prevent a foreign object, such as iron powder produced in the driving gear train, from entering the hydrostatic transmission. The system includes an L-like-shaped center section (5) on which the hydrostatic transmission is offset such that an imaginary plane which includes a motor mounting surface passes in proximity to the axis of a pump shaft (3). The pump shaft (3) is disposed perpendicular to the axles. The motor shaft (4) is disposed in parallel thereto. A hydraulic pump is positioned between the hydraulic motor and the axles, so that the housing for the hydrostatic transmission, axles and driving gear train, is smaller in width to thereby make the system more compact.

摘要： An axle driving unit having a housing (21, 22) for supporting a first axle (17) for mounting thereon a first driving wheel (3L), and a longer second axle (18) for mounting thereon a second driving wheel (3R). The axle driving unit is eccentrically mounted on a body frame (1) in proximity to the first driving wheel (3L). A speed change transmission (T) is disposed in an enlarged region of the housing that extends substantially perpendicularly with respect to the axles (17, 18). The axle driving unit can thus be easily disposed to the side of a chute (6) of a rear-discharge type lawn tractor.
