摘要： An axle driving apparatus for being mounted on the body frame of a vehicle and for independently rotating drive wheel members. The axle driving apparatus includes a first axle driving unit (18L) leaving a housing (40) and a single axle (20L), the single axle (20L) defining a proximal end portion rotatably mounted in the housing (40) and a distal end portion extending outwardly from a first side of the housing (40). 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 (22) is disposed within the enlarged region. The speed change assembly (22) 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). The first axle driving unit (18L) is used in conjunction with a second axle driving unit (18R) which is adjacently disposed to the first axle driving unit (18L) on the body frame of the vehicle and which is of substantially similar construction. However, the second axle driving unit (18R) features a single axle (20R) which extends outwardly from a second, opposite side of the housing (40) such that the axles (20L, 20R) are oppositely disposed.

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.

摘要： An axle driving apparatus includes a housing for supporting an axle, a hydrostatic transmission including a hydraulic pump, a hydraulic motor, and a center section. The center section has a pump mounting surface and a motor mounting surface substantially perpendicular to each other. A rotational axis of a motor shaft is disposed lower than a plane located at the pump mounting surface. The center section includes a narrow portion and a wide portion. The narrow portion is defined between a first side and a second side opposite the first side in a direction along the rotational axis of the motor shaft. The wide portion is formed adjacent to the narrow portion. A first extension of the wide portion is defined by a width that extends from the first side in the direction along the rotational axis of the motor shaft and a length that extends in a direction perpendicular to the rotational axis of the motor shaft. A second extension of the wide portion is generally defined by the pump mounting surface formed thereon.
