Abstract
A dual clutch mechanism includes an input shaft, a first output shaft and a second output shaft. The mechanism includes a pair of clutch arrangements each having a set of intermeshed annular driving and driven discs frictionally compressible to selectively drive either the first or second output shaft via the input shaft. Each of the clutch arrangements has a separate driving plate and a common driven plate. The rotational inertia of the driving plates are reduced by associating the driving plates with inner diameters of the annular discs, as opposed to their outer diameters. Cooling and/or lubricating fluid is separately supplied to each of the sets of discs such that the flow rates of fluid to the sets of discs can be independently increased or decreased without a corresponding increase or decrease in the flow rate to the other set of discs.
