Drive device for electric vehicle, has expansion machine formed as gas turbine that has combustion chamber for mixture of fresh air and solid, liquid and/or gaseous fuel, where combustion chamber is connected upstream of turbine

摘要

The device (1) has an electric machine (4, 5) i.e. hub motors (6, 7), operatively connected with a drive wheel of a vehicle (2), and an expansion machine (28) operatively connected with another electric machine (13) and formed as a gas turbine (27). The gas turbine is utilizable as an engine block heater, and has a combustion chamber (16) for mixture of fresh air and solid, liquid and/or gaseous fuel, where the combustion chamber is connected upstream of a turbine (20) that is connected with the latter electric machine. An independent claim is also included for a method for operating a drive device.
