Abstract
A dual automatic mechanically actuated wet clutch device, for operation within a fluid tight housing, for a dual input shaft transmission that includes tightly specified average spacing between friction plate surfaces where the average spacing is selected from between about 0.05 mm to about 0.25 mm in an open position. The clutch has at least first and second independently actuatable clutch portions, and at least one clutch pack in the first or second clutch portion; and mechanical apparatus provided to move friction plates in at least one of the clutch portions toward each other so that they engage. The invention also includes apparatus and methods for adjusting and maintaining the spacing between the friction plate surfaces.
