Powertrain for car, has speed translator provided between transmission output and bladed primary wheel of hydrodynamic clutch such that primary wheel rotates with greater speed as transmission output

摘要

The powertrain has an exhaust-gas turbine (22) and a fresh-air compressor (24) connected to a drive shaft (2) of an internal combustion engine (1) through a continuously variable transmission (16), where a hydrodynamic clutch (8) is provided between the drive shaft and the transmission. The clutch includes a bladed primary wheel (10) and a bladed secondary wheel (7) together forming a torus-shaped working chamber. A speed translator (28) is provided between a transmission output (15) and the primary wheel, so that the primary wheel rotates with a greater speed as the transmission output.
