Abstract
A power-split transmission for a vehicle comprises a forward-reverse transmission module, an epicyclic module and a secondary power branch. The forward-reverse power shuttle module () comprises an input shaft () coupled to a primary motor () and an output shaft (). Also included, first and second clutches () are alternatively engageable to close respective forward and reverse drive paths between the input shaft and output shaft. Engagement of the first clutch couples the input shaft directly to the output shaft. Engagement of the second clutch couples the input shaft to the output shaft via first and second gear sets () which each comprise a plurality of meshed gears. One of the gear sets () comprises an odd number of gears and the other gear set () comprises an even number of gears. The epicyclic module comprises a first epicyclic input connected to the output shaft of the forward-reverse transmission module, a second epicyclic input connected to an output side of the secondary power branch, and an epicyclic output. The secondary power branch derives power from the primary motor via the first gear set.
