Abstract
The present invention is a device for transferring power flow from a multidisplacement engine to a transmission. The device includes an enclosed housing having a first shell on the engine side, a second shell on the transmission side, with the housing at least partially filled with oil and connected to an external oil pump. The device also includes a planetary gear set comprising an outer ring gear, a set of intermediate planet gears contained within a planet carrier, and a sun gear attached to a stator, a first clutch pack connecting the housing and the ring gear when engaged, a piston means designed to engage the first clutch pack, and a second clutch pack which connects the ring gear with the sun gear when engaged. A preloaded diaphragm spring connects the second clutch pack with the ring gear. First and second damper spring assemblies are also disclosed.
