Abstract:
A transmission for a vehicle with a hydrostatic transmission and a power shift device interposed in tandem in a drive power transmission path comprising:a housing; first and second plate-like members disposed within said housing in such a manner as to be positioned away from each other along a drive power transmission direction, while respectively having each-other facing surfaces, through which said first and second plate-like members face each other; an input shaft extending through said first plate-like member; an output shaft disposed parallel with the input shaft and away from the same in a plate surface direction of the first plate-like member; a hydraulic pump body supported on a surface opposite to the each-other facing surface of the first plate-like member, and operatively connected to the input shaft; a hydraulic motor body supported on the each-other facing surface of the first plate-like member, and being adapted to drive the output shaft upon receiving operational fluid discharged from the hydraulic pump body; an auxiliary pump disposed on the second plate-like member and being adapted to be driven through the shaft; and wherein the second plate-like member supports thereon a clutch shaft of the power shift device, and has a hydraulic fluid passage for supplying therethrough pressurized hydraulic fluid discharged from said auxiliary pump to a hydraulic clutch on said clutch shaft.
