Continuously variable power-split vehicle transmission
Abstract:
A continuously variable power-split transmission is provided and comprises an epicyclic module (14) having an input shaft (38) drivingly coupled to a primary motor (20). Three compound planets (52, 60, 62) are supported on a common planet carrier (54) and each engage respective sun gears (50, 56, 58). The transmission further comprises a continuously variable drive connection (16) between the primary motor and the planet carrier. A first sun gear (50) of the epicyclic module is disposed on the input shaft. A first power split output (80) is provided by an output side of the continuously variable drive connection. The second and third sun gears (56, 58) are connected to second and third power split outputs (64, 66) respectively. A downstream torque consumer (18) derives power selectively from one of the first, second and third outputs.
