摘要： A transaxle apparatus (10;20) comprising an axle (12L,12R;22L,22R) having an axis and a housing (46,47) supporting the axle (12L,12R;22L,22R), wherein the housing (46,47) includes a first housing member (46) and a second housing member (47) which are joined to each other through a joint surface along the axis of the axle (12L,12R;22L,22R). A hydraulic motor (40) is disposed in the housing (46,47), wherein the hydraulic motor (40) includes a cylinder block (43) and a motor shaft (41) engaged to the cylinder block (43) and extended parallel to the axis of the axle (12L,12R;22L,22R). A member (62) is disposed in the housing (46,47) and incorporates a pair of kidney ports (62a,62b) fluidly connected to the cylinder block (43). A pair of caps (54a,54b) are fluidly connected to the cylinder block (43), and a gear train (135) is disposed in the housing (46,47) so as to drivingly connect the motor shaft (41) to the axle (12L,12R;22L,22R). The pair of caps (54a,54b) are disposed in the housing (46,47) so as to be fluidly connected to the respective kidney ports (62a,62b) and are extended and opened outward from the housing (46,47) so as to receive and deliver fluid from and to a hydraulic pump (30) disposed separate from the housing (46,47).

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.
