摘要： An axle driving apparatus for a vehicle includes an axle, a vertical pump shaft, a hydraulic pump having a movable swash plate, a pair of trunnion shafts provided coaxially at respective opposite sides of the movable swash plate, a hydraulic motor having a motor shaft drivingly connected to the axle, and a housing containing the hydraulic pump, the hydraulic motor, and the axle. The housing includes a first housing member and a second housing member separably jointed along a vertical plane perpendicular to a rotary axis of the axle. A rotary axis of the hydraulic pump is substantially parallel to the vertical plane. The hydraulic pump is entirely disposed in the first housing member. A rotary axis of the trunnion shafts is substantially perpendicular to the vertical plane. One of the trunnion shafts is rotatably supported by the first housing member and the other of the trunnion shafts is rotatably supported by the second housing member, whereby the movable swash plate is slantingly rotatably supported in the housing.

摘要： An axle driving system which houses in a housing thereof a hydrostatic transmission, axles, and a driving gear train for connecting output 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 therein contains the hydrostatic transmission and a second chamber 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 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. The pump shaft is disposed perpendicular to the axles. The motor shaft 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 articulate vehicle comprises a first frame disposed at one of front and rear portions of the vehicle and a second frame disposed at the other of front and rear portions of the vehicle. The first frame supports a first transaxle apparatus supporting a first axle. The second frame supports a second transaxle apparatus supporting a second axle. Proximal ends of the frames with respect to the vehicle are coupled to each other through a coupling part so that the first and second frames are rotatable relative to each other around a vertical axis according to steering operation. An engine is mounted on the first frame. A first hydraulic motor is integrally assembled in the first transaxle apparatus so as to drive the first axle. A working vehicle is equipped at a distal side of the second frame with respect to the vehicle. A second hydraulic motor is integrally assembled in the second transaxle apparatus so as to drive the second axle. A hydraulic pump is mounted on either the first or second frame, drivingly connected to the engine, and fluidly connected to both the first and second hydraulic motors.

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) having 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.
