Abstract
A clutch for a manual or automatic transmission according to the present invention includes an axial fan or turbine disposed on a shaft extending between the clutch and the transmission. Air is supplied to the turbine through one or more radial passageways between the clutch and transmission housings and is provided through an annular passageway around the shaft. Air from the annular passageway is then dispersed generally radially between the clutch plates or disks and other clutch components to absorb and carry away heat generated during clutch operation.
