摘要： A transaxle apparatus is constructed so that left and right axles, two hydrostatic transmissions (HSTs), one for driving a vehicle and the other for steering it, and a differential unit for differentially connecting said axles with each other are together contained in a housing. The driving HST is disposed so that its hydraulic pump and motor are aligned along either a left or right side of the housing. The steering HST is disposed so that its hydraulic pump and motor are aligned along either a front or rear side of the housing. The differential unit is laterally opposite to the driving HST. Either the left or right axle crosses the driving HST between its hydraulic pump and motor. The two HSTs are provided with one or two flat center sections disposed in the housing. The cylinder blocks of the hydraulic pumps and motors of the two HSTs are mounted on either a top or bottom surface of the center section or sections. Power transmission mechanisms for transmitting output power from the hydraulic motors of the two HSTs into the differential unit are disposed on an opposite side of the center section(s) as the cylinder blocks. A charge pump may be attached onto the center section, and a conduit for sending fluid discharged from the charged pump into one or both HSTs may be partly extended outside the housing so as to be cooled by the atmosphere.

摘要： An object of the present invention is to provide a working vehicle having such a fine traveling feel that the vehicle traveling speed is increased in proportion to operation of a speed change operation means similar to a normal passenger car, while reducing noise and fuel consumption of an engine at the time of traveling in middle or high speed. While an operation degree of the speed change operation member is increased from 0 to a certain value, the increase of the vehicle traveling speed is produced by a first increase rate of the engine rotation speed and a first increase rate of a speed ratio (output/input rotation speed ratio of a speed change mechanism) increase rate, and while the operation degree of the speed change operation member is increased from the certain value, the engine rotation speed is kept to be the rated value and corresponding thereto, the increase rate of the speed ratio is set to a second increase rate of the speed ratio larger than the first increase rate of the speed ratio so that the vehicle traveling speed is always increased substantially in proportion to the acceleration operation of the speed change operation member.
