摘要： 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.

摘要： A carrier has a rear wheel driving transmission which comprises a drive shaft extending longitudinally of the body of the carrier, and an output shaft disposed approximately horizontally away from an intermediate shaft below the drive shaft. This arrangement renders the transmission flat, thereby making it possible to position a power take-off device in a clearance between the transmission and a body frame. Consequently, the rear wheels of the carrier can be arranged at a rearward portion of the body, with the engine and load carrying platform of the carrier positioned at a low level, to give improved running stability to the carrier.

摘要： In a tractor having a mid-PTO shaft (13) and a rear-PTO shaft (22) which are journalled in a transmission casing (10) disposed between left and right rear wheels (12), a PTO-selecting clutch (20) for selectively operating both of or any one of the PTO shafts is disposed on a rear end portion (13a) of the mid-PTO shaft. The selecting clutch includes an input gear (17), drivenly connected to a drive shaft (14) through a PTO-clutch (15) and through a first gearing (16), and an intermediate gear (19) drivingly connected to the rear-PTO shaft. In a preferred embodiment, a second rear-PTO shaft (24) is provided on which the intermediate gear is fixedly mounted. The selecting clutch disposed on the mid-PTO shaft contributes to make the structure and parts of power take-off transmission assembly largely common between tractors having both of the mid- and rear-PTO shafts and having only a mid-PTO shaft.
