Abstract
An axle driving apparatus wherein a hydraulic motor and a hydraulic pump for a hydro-static-transmission are housed in a transmission casing of the axle driving apparatus and a center section for connecting the hydraulic motor and hydraulic pump is disposed in the transmission casing, the center section being fixed at the butt Joint portion at the transmission casing, and an oil passage from the hydraulic pump to the hydraulic motor at the center section is bent at a right angle so as to extend the motor shaft in parallel to the axles, so that the rotation direction of the motor shaft conventionally changed by bevel gears is changed by the oil passages in the center section.
Claims20
A hydraulic transaxle, comprising:
- a casing formed of a first casing section and a second casing section joined along a junction surface, said junction surface defining a plane;
- an axle rotatably supported within said casing, said axle having a longitudinal axis parallel to said junction surface;
- a hydrostatic transmission for driving said axle including a hydraulic pump and a hydraulic motor, said hydraulic motor including output means having a longitudinal axis;
- transmitting means having a longitudinal axis disposed within said casing for transmitting power from said hydraulic motor, wherein the longitudinal axis of said output means and the longitudinal axis of said transmitting means are disposed parallel to the longitudinal axis of said axle;
- a different gear unit disposed within said casing and connecting said transmitting means and said axle;
- and
- input means for transmitting power to said hydraulic pump.
