Transmission system for e.g. thermal-electric hybrid car, has primary variable speed drive cooperating with secondary variable speed drive for forming transmission unit for moving with continuous variation between urban and common shafts

摘要

The system has a drive shaft (7) connected with an internal combustion drive engine (1) via a drive clutch (3). An urban shaft (6) is connected with an internal combustion urban engine (2) via an urban clutch (4), where the engines e.g. petrol engines, are provided in a thermal twin-engine drive train. A common shaft (8) is connected with drive wheels. A primary variable speed drive (13) cooperates with a secondary variable speed drive (20) for forming a transmission unit for moving with continuous variation between the urban and common shafts.
