ABSTRACT:
A transmission assembly adapted to be mounted on a front of a vehicle axle casing as a substitute for a hydrostatic transmission comprises a transmission casing (1) and a drive shaft (2) at a high level, a speed-change shaft (4) at a low level, and an intermediate shaft (3) at a level intermediate between the drive and change shafts. These shafts extend within the transmission casing axially of this casing. The intermediate shaft is located aside in a direction across the casing. A clutch (5) is disposed on the drive shaft at an axial mid portion of this shaft, and a hollow shaft (6) which is driven to rotate by the drive shaft through the clutch is disposed on the drive shaft at one axial side of the clutch. A first mechanical speed-change mechanism (7) is disposed between the hollow shaft and intermediate shaft, whereas a second mechanical speed-change mechanism is disposed between the intermediate shaft and change shaft. Configuration of the transmission casing may be simplified, while the number of change ratios obtainable is greatly increased.
