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 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.

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： A driving apparatus (2) for speed changing and steering of a vehicle consists of a first driving unit (21) for speed changing in advancing and reversing and a second driving unit (22) for steering, which are arranged in a longitudinal row and are attached to a vehicle chassis (12). Each of the first driving unit (21) and the second driving unit (22) has a common structure, which comprises a housing and an HST and left and right differential output shafts contained in the housing. A left first differential output shaft (40L) and a left second differential output shaft (44L) are connected with each other so as to be rotated in the same direction, and a right first differential output shaft (40R) and a right second differential output shaft (44R) are connected with each other so as to be rotated in opposite directions. Both first and second HSTs of the first driving unit (21) and a second driving unit (22) receives power from engine (11) through a common single belt (30). A movable swash plate (57) of a hydraulic pump (51) of the first HST is connected to a speed change pedal (15) and a movable swash plate (76) of a hydraulic pump (71) of the second HST is connected to a steering wheel (14).
