摘要： A hydrostatic transaxle comprises: a housing, an interior space of the housing serving as a fluid sump; an axle supported by the housing; a hydrostatic transmission disposed in the housing so as to drive the axle, the hydrostatic transmission including a hydraulic pump disposed in the housing, a hydraulic motor disposed in the housing, and a center section disposed in the housing, wherein the hydraulic pump and the hydraulic motor are mounted onto the center section, and wherein the center section is formed therein with a fluid circuit for circulation of fluid between the hydraulic pump and the hydraulic motor, and formed with an outwardly opened hole connected to the fluid circuit; a valve holding member fitted into the hole; and a relief valve connected to the fluid circuit through valve holding member. The relief valve is provided with a fixed flow restricting means for passing a specific amount of fluid from a higher-pressurized portion of the fluid circuit to a lower-pressurized portion of the fluid circuit. The relief valve allows fluid after passing through the fixed flow restricting means to flow to the lower-pressurized portion of the fluid circuit when a differential pressure between a primary pressure of fluid before passing through the fixed flow restricting means and a secondary pressure of fluid after passing through the fixed flow restricting means is zero or within a predetermined range.

摘要： In a working vehicle, a variable output HST and a planetary gear unit are connected with an engine, which is supported on a vehicle frame closer to a first side of a fore and aft direction of the vehicle in vibration free manner so as to together constitute a driving-side unit, which is integrally supported on the vehicle frame in vibration free manner. A transmission case of a transmission is fixedly supported on the vehicle frame closer to a second side of the fore and aft direction of the vehicle with a distance from the driving-side unit. An output element of the planetary gear unit is operatively connected with a wheel drive train of the transmission via a shaft coupling extending along the fore and aft direction of the vehicle.
