<p>A continuously variable power-split transmission (10) for transferring torque from a primary motor (20) to a differential gear (24) is provided. The transmission comprises an epicyclic module (14), a continuously variable drive connection (16) and a direct shift transmission module (18). The epicyclic module comprises a first input (38) drivingly coupled to the primary motor, a second input (54) and first and second outputs (64, 66). The continuously variable drive connection (16) is drivingly coupled between the primary motor and second input (54) of the epicyclic module. The first and second epicyclic outputs are alternatively coupled to the differential gear (24) via respective torque transfer paths provided by the direct shift transmission module. Each path includes a clutch (C2, C3) and a synchromesh unit (112, 94) which allows selection of one of a plurality of torque transfer sub-paths. Each clutch comprises an input side and an output side.</p> |
