ABSTRACT:
In a vehicle transmission assembly comprising a transmission casing (15) which supports axles (16) of forcedly driven rear wheels (12) and includes therein a rear-PTO shaft (18) and mid-PTO shaft (19), first input shaft (28) of a lower level and second input shaft (27) of a higher level for transmitting power into the transmission casing are provided such that the first input shaft is located aside in a direction across the casing. The first input shaft is connected drivingly to the wheel axles through a change speed gearing (31) disposed at a relatively high level, differential gearing (32) and final speed-reduction meshing gears (72, 73). A PTO-clutch (40) is disposed on the rear of the transmission casing between a drive shaft (38), co-axial with and coupled to the second input shaft, and a hollow clutch shaft (39) mounted rotatably on the drive shaft. The clutch shaft is connected drivingly to the respective PTO-shafts through a PTO-shaft drive assembly which is disposed at a rear end portion within the transmission casing and includes a PTO-selecting clutch (47). A compactness of the transmission assembly and transmission casing is assured owing to the arrangement of change speed gearing (31) and PTO-clutch (41).
