CLUTCH ASSEMBLY WITH A GEAR PUMP

摘要

A drive system is provided for coupling a clutch assembly with a pump assembly that provides fluid power to cool, lubricate and control the operation of the clutch. The drive system comprises a drive coupling rotatably supported on an input shaft by a plurality of bearing members. The bearing members permit the drive coupling to rotate independent of the rotation of the input shaft. The drive coupling is provided with at least two splined surfaces for engaging a corresponding splined surface on both the clutch assembly and the pump. The drive system counteracts radial loads generated within the pump and moment loads generated at the splined connections to the prevent premature wear or damage to the pumping elements and mating components.
