Flywheel clutch assembly with brake

Claim 1

In combination with a rotatable housing formed of a flywheel and spaced rotatable end plates mounted on a pair of spaced bearings on a drive shaft supported in bearings in which it is to be driven by said flywheel, a clutch unit disposed internally of the flywheel between said spaced bearings and comprising a plurality of clutch plates connected to the flywheel and a plurality of clutch discs connected to said drive shaft, a non-rotatable housing axially spaced from said rotatable flywheel, a brake within said non-rotatable housing comprising a plurality of brake plates connected to said non-rotatable housing and a plurality of brake discs connected to said drive shaft, first actuating means disposed within said rotatable flywheel and movable in one direction for selectively frictionally engaging said clutch plates with said clutch discs, said actuating means including an enclosure concentric with said drive shaft and adapted to slide axially thereof, a radially disposed partition located within said enclosure and separating the interior thereof into first and second axially spaced chambers, said partition being relatively axially immovable relative to said drive shaft, and fluid passage means communicable with a source of pressurized fluid for selectively pressurizing one of said chambers and thereby causing said enclosure to move axially of said drive shaft, and second actuating means within said non-rotatable housing for frictionally engaging said brake plates with said brake discs.
