Patent ID: 7216735

Claim:
Hybrid drive system for vehicles that comprises: A combustion engine ( 1 ) with an air input ( 9 ), an alternator ( 22 ) and a fuel tank ( 18 ); A pneumatic compressed air motor ( 2 ) with an electro-pneumatic control valve ( 14 ), an air exhaust ( 8 ) and a compressed air tank ( 13 ); A clutch ( 6 ) and a gearbox ( 7 ) for applying drive of the combustion engine and pneumatic motor ( 1 , 2 ) Characterised, in that this system additionally comprises: A mechanical coupling device ( 3 ) for coupling/uncoupling the respective combustion engine ( 1 ) and pneumatic motor ( 2 ), so that the drive of both may be added together; A pneumatic coupling device made up of a pneumatic tube ( 10 ), an electro-pneumatic valve ( 11 ) and an air filter ( 12 ) with an outlet to the outside, for connecting the air exhaust ( 8 ) of the pneumatic motor ( 2 ) to the air input ( 9 ) of the combustion engine ( 1 ), so that comburent surpercharging is provided to the combustion engine ( 1 ); and An electronic control unit ( 19 ) for governing the combustion engine ( 1 ), the mechanical coupling device ( 3 ), the clutch ( 6 ), the gearbox ( 7 ), the electro-pneumatic valve ( 11 ), the control valve ( 14 ), and the alternator ( 22 ).
