Drive unit with an internal combustion engine and an exhaust gas turbocharger

摘要

The invention relates to a drive unit, comprising an internal combustion engine with a crankshaft; an exhaust line; an exhaust gas turbine which is acted on by the exhaust gas line, which is arranged downstream of the internal combustion engine and has the purpose of transmitting a positive torque to the crankshaft in the traction mode; a hydrodynamic unit which is arranged downstream of the exhaust gas turbine and has two turbine blades which form a torus-shaped working chamber; the hydrodynamic unit has a drive connection to the drive train; and a parking brake is provided for securing the primary turbine wheel of the exhaust gas turbine.
