Abstract
A fluid coupling transmission is adapted for interposition between the engine and the propulsion unit of a marine drive. The fluid coupling transmission provides variable speed operation in both forward and reverse. A fluid pump is drivingly connected to the engine crankshaft, and is adapted to drive a forward turbine and a reverse turbine. The reverse turbine is disposed between the fluid pump and the forward turbine, and includes a series of variable position vanes for providing variable power output from the transmission. A one way clutch is positioned between the forward turbine and an output shaft of the transmission, and a planetary gearset is disposed between the reverse turbine and the output shaft. A carrier member extends concentrically relative to the output shaft along a portion of its length, and the planet gears of the planetary gearset are pivotably mounted to the carrier member. The carrier member is provided with a clutch mechanism for selectively engaging the output shaft, and a brake band is provided for selectively maintaining the carrier member stationary. The brake band and clutch mechanism are selectively engageable so as to prevent rotation of the output shaft, impart rotation through the reverse turbine and planetary gearset to propel the boat in a reverse direction, or to impart rotation to the output shaft through the forward turbine and the reverse turbine to propel the boat in a forward direction.
