Abstract:
1. A hydraulic transaxle comprising: a housing forming a fluid sump; a pair of axles disposed in the housing; a differential unit disposed in the housing so as to differentially connect the axles to each other; a hydraulic pump disposed in the housing, the pump having a pump shaft extended from the housing; a hydraulic motor disposed in the housing, the motor having a motor shaft; a motor output gear being non-relatively rotatably fitted on the motor shaft and drivingly connected to the axles; a diametrically large gear meshing with the motor output gear; a diametrically small gear meshing with a bull gear of the differential gear unit a counter shaft coaxially supporting the large and the small gear, the counter shaft axially having one end and the other end; and a center section detachably fixed in the housing and fluidly communicating the pump and the motor, the center section having a pump mounting surface and a motor mounting surface at a right angle to each other, whereby the pump shaft of the pump extends perpendicularly to the axles, and the motor shaft of the motor extends parallel to the axles, wherein an opening though which the motor shaft extends is formed in a surface opposite of the motor mounting surface of the center section, and wherein a support portion is formed by the center section, the one end of the counter shaft being inserted into and supported by the support portion and the other end of the counter shaft being supported by the housing.
