A housing for hydraulic units includes a single cast unitary hollow housing having a continuous side wall extending between opposing forward and rearward walls to form an enclosed housing. Preferably, the continuous side wall includes opposing top and bottom walls, and opposing right and left side walls. A rotary axis is located between the forward and rearward walls, and is generally centered in an opening formed in the forward wall. Access openings are provided in the continuous side wall, transverse to the rotary axis, for installation of components within the housing during assembly.

Housing system for hydraulic units

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.
