    Abstract: A housing of a hydraulic pump is configured to have a servo unit detachably attached thereto so as to control tilt direction and angle of its movable swash plate. A port block is formed therein with a pair of main ports and, and a pair of main fluid passages and fluidly connecting respective main ports and to cylinders in its cylinder block. Main ports are used to have respective external pipes connected thereto so as to fluidly connect the hydraulic pump to a hydraulic motor disposed outside of the hydraulic pump, thereby constituting a hydrostatic transmission.

    Abstract: A transaxle comprises a hydrostatic transmission (HST), an axle, a gear train interposed between the HST and the axle, a casing and a partition. The casing defines an HST chamber and a gear chamber. The HST is disposed in the HST chamber. The gear train and the axle are disposed in the gear chamber. The partition is disposed in the casing so as to separate the HST chamber and the gear chamber from each other. The partition has an opening through which a hydraulic motor of the HST passes to extend from the HST chamber into the gear chamber so as to be drivingly connected to the gear train. The partition obstructs a flow of fluid between a fluid sump in the HST chamber from a fluid sump in the gear chamber.

    Abstract: An apparatus comprises a hydrostatic transmission and a casing incorporating the hydrostatic transmission. The hydrostatic transmission includes a hydraulic pump, a hydraulic motor and a center section. The hydraulic pump and the hydraulic motor are attached to the center section that is formed therein with a fluid sump fluidly connecting the hydraulic pump to the hydraulic motor. At least a bottom portion of the center section is submerged in a fluid sump in the casing. A charge port for fluidly connecting the fluid sump to the fluid passage is open at the bottom portion of the center section in the fluid sump, The bottom portion of the center section is downwardly convex so as to have an apex at the lowest portion. The opening of the charge port is directed to the apex of the convex bottom portion of the center section.

    Abstract: A hydraulic transaxle of the present invention includes an axle, a hydraulic static transmission (“HST”), a center case that has pair of oil passages for circulating the hydraulic oil between the hydraulic pump and the hydraulic motor, and a gear mechanism that transmits an output of the HST to the axle. A case supports the axle and accommodates the HST while also forming an oil reservoir. A hydraulic motor of the HST includes a motor shaft, a cylinder block with a plurality of cylinders fixed to the motor shaft, a plurality of pistons inserted into the cylinders, a fixed swash plate abutted by the plurality of pistons, and a fixed swash plate holder that supports the fixed swash plate with respect to the case. The motor shaft of the hydraulic motor is supported by the center case and the fixed swash plate holder.
