A SUPERCHARGING SYSTEM FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a supercharging system (6) for an internal combustion engine comprising a turbo charging device with a turbine (7) and a compressor (8), said compressor having a compressor shaft (8a); a planetary gear (25) coupled to said compressor shaft (8a) and a drive shaft (32); a clutch unit (18); a power transmission for connecting a crank shaft (4) of the combustion engine (1) to said drive shaft (32) via the clutch unit (18); and an electric motor or electric generator (20) connected to said drive shaft (32). Said compressor shaft (8a) is at least on one end movably arranged between said compressor (8) and said planetary gear (25) to allow relative movements between said compressor (8) and said planetary gear (25).
