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 axle driving apparatus of the invention is available for an economical vehicle having a belt type stepless transmission. The axle driving apparatus includes a pair of axles connected to respective drive wheels, a propelling transmission mechanism, and a steering transmission mechanism. The propelling transmission mechanism is drivingly connected to said prime mover through said belt type stepless transmission so as to transmit speed-variable output rotation of said belt type stepless transmission to both said axles, thereby rotating said axles together at various speeds in a common direction selected from two opposite directions for forward and backward traveling of said vehicle. The steering transmission mechanism is drivingly connected to said prime mover so as to transmit two oppositely directive output rotations to said respective axles, thereby differentially rotating said axles at various differences of rotational speed between said axles. If the belt type stepless transmission comprises first and second belts through a variator pulley and the second belt is looped over an input pulley of the propelling transmission mechanism, the first belt may be looped over an input pulley of the steering transmission mechanism. Alternatively, the first belt may be looped over a power taking-out pulley provided on an input shaft of the steering transmission mechanism.

摘要： A hydrostatic transmission (HST) including a hydraulic pump is contained in a housing having upper and lower housings. An input shaft of the hydraulic pump projects outward from the upper housing. A cooling fan is provided on an upper end of the input shaft. A conduit is disposed within an area between the fan and the upper housing. The conduit extends between first and second couplings and is in communication with an oil sump formed in the housing. A pumping device, which rotates with the input shaft, is disposed within the second coupling for forcedly circulating oil between the conduit and the sump. Alternatively, a reservoir is disposed on an outer wall of the housing forming a second oil sump. A level of oil in the second oil sump is lower than a level of oil in the oil sump formed in the housing. The second oil sump communicates with the atmosphere whereas the oil sump formed in the housing is separated from the atmosphere. A siphon communicates both sumps with each other. The driving apparatus may incorporate either the conduit, the reservoir, or both the conduit and the reservoir.
