Abstract
An integrated drive arrangement for a vehicle propulsion system for transmitting vehicle drive torque and for independently driving external implements. The drive arrangement includes a power input shaft having a number of axially spaced drive gears and being driven by a prime mover. The pump shaft of a variable displacement pump is drivingly connected with one of the drive gears of the power input shaft. A fixed displacement motor is connected in closed circuit to the variable displacement pump. A number of drive pinions are spaced axially along an intermediate shaft which is spaced from the power input shaft and are connected to the intermediate shaft and the power input shaft by an electromagnetic clutch. First and second power take-off shafts are drivingly connected with the intermediate shaft such that the power input shaft imparts independent rotation to the power take-off shafts and the pump shaft.
