ABSTRACT:
A power transmission device for use in a motor vehicle in which an engine is mounted on the front part and a transmission case is mounted on the rear part of the vehicle. A plurality of shifting shafts are axially supported within the transmission case in parallel with one another. Between these shift shafts, a plurality of shifting gear trains, which are engaged and disengaged by a hydraulic clutch, are provided. One of the shifting shafts is connected to the output side of a wet multi-disc main clutch which is disposed in a separate chamber within the transmission case. The input side of the clutch is connected to the engine. An oil pump is disposed within the transmission case. Oil discharged from the pump is controlled by a control valve and is then supplied to the respective oil clutches and bearings through an oil passage disposed along the wall of the transmission case and an oil passage disposed in the axial direction within the shifing shaft. The engine power, which is changed in speed, is transmitted to the front wheels through a front wheel drive shaft and also transmitted to an agricultural machinery through a PTO shaft.
