ABSTRACT:
A start-up clutch including a disk clutch having an outer disk carrier and an inner disk carrier with a multi-disk clutch pack disposed therebetween. The multi-disk clutch pack is adapted to engage and provide torque translation between the inner and the outer carriers. A piston is adapted to be actuated by fluid pressure to cause the multi-disk clutch pack to engage. A first cavity is adapted to be selectively supplied with pressurized fluid to actuate the piston. A second cavity is adapted to be selectively supplied with pressurized fluid to provide cooling to the multi-disk clutch pack. A first fluid passage adapted to provide pressurized fluid to the first cavity, and a second fluid passage is adapted to provide pressurized fluid to the second fluid passage.
