Continuously adjustable drive for vehicle

摘要

The drive encompasses a torque convertor (20) which has three rotors of an impeller (21) and first and second turbines (22,31). A bridging coupling (25) can be activated for coupling the impeller with the first turbine. A hydraulic brake (27) located on a first turbine shaft (23) is connected with the first turbine and is fixed on a housing (39). A second turbine shaft (32) connected with the second turbine, is connected via a one-way coupling (33) with a belt pulley of a drive (40), whereby the one-way coupling only transfers one force when the second turbine rotates in an opposite direction like the impeller. A hydraulic coupling (26) can be activated for coupling the first turbine shaft with the second turbine shaft.
