Motor vehicle launching element and method for operating a motor vehicle

摘要

The element e.g. hydrodynamic coupling (2), has a secondary side that is hydrodynamically or electro-dynamically rotary-driven by a rotary-driven primary side. An electrical machine (1) e.g. electro-dynamic brake, retards and retains the secondary side. The electrical machine comprises a stator (1.1) and a rotor (1.2), which are coupled with each other by an electromagnetic reciprocal effect. The rotor is connected with the secondary side of an adjustable coupling in a torque-proof manner to retard the secondary side. An independent claim is also included for a method for driving a motor vehicle by a motor vehicle drive train.
