The invention relates to a locking device (SV) for an electric motor drive unit (EM-AE), wherein the locking device (SV) has a locking mechanism for locking a lockable shaft (W) of the electric motor drive unit (EM-AE), and an electric drive (EA) for actuating the locking mechanism, said drive being received by a housing (SV-G) of the locking device (SV) together with the locking mechanism. The housing (SV-G) of the locking device (SV) additionally receives a separate assembly of contacting means comprising at least two contact brushes (2a, 2b, 3a, 3b) for an external excitation of a rotor of a synchronous machine of the electric motor drive unit (EM-AE), said rotor being connected to the shaft (W). The invention additionally relates to an electric motor drive unit (EM-AE), in particular for driving a vehicle, comprising such a locking device (SV), and to a vehicle comprising such an electric motor drive unit (EM-AE).
