POWERTRAIN COMPRISING AN OPTIMIZED ENERGY RECOVERY SYSTEM

摘要

The invention relates to a powertrain comprising: - a variable ratio transmission device ( 18) having an input shaft ( 16) coupled to an engine (12) and an output shaft coupled to a driven unit (25); - a three-way power split transmission device (34) comprising three input/output couplings (36, 40, 44), a first of which is coupled to a flywheel (38) and a second of which is coupled to an electrical machine (42), characterized in that the third input/output coupling of the three way power split transmission device (34) is mechanically coupled to the engine (12) and to the input shaft (16) of the variable ratio transmission device (18).
