DUAL RATIO DRIVE FOR VARIABLE SPEED HYBRID ELECTRIC SUPERCHARGER ASSEMBLY

摘要

An example engine assembly includes: an electric motor (402) coupled to a ring gear (408) via different gear sets (404, 406; 414, 416), each provided with a clutch. An engine is coupled to a carrier (418), and the planetary gear co-operates with a supercharger. The gear ratio between the motor and the engine or the supercharger can be changed by selectively applying the clutches.
