ABSTRACT:
A cooling system for a vehicle clutch including a cooling fluid distribution means and a heat exchange means. A bell housing encloses the clutch assembly and provides a sump for containing cooling fluid. A clutch pressure plate has a plurality of pickup tubes formed on its periphery which are passed through the cooling fluid as the pressure plate rotates with the engine flywheel. The cooling fluid is forced through the pickup tubes into the interior of the clutch assembly where the cooling fluid draws heat from the clutch elements and then drains back into the sump. The inlet openings of adjacent pickup tubes are offset with respect to one another to increase the flow of cooling fluid. The rotation of the flywheel and the pressure plate generates a flow of the cooling fluid in the pool. A sump pan is connected to the bell housing and includes a baffle for diverting the flow of cooling fluid into the sump pan which is formed with a corrugated bottom and finned sides to function as a heat exchange means.
