摘要:
A wheel hub drive (1) is disclosed, having an electric motor, wherein the electric motor comprises a stator (2) and a sleeve-shaped rotor (4), a ring structure (10) that is coaxial to the rotor (4) is arranged on at least one inner mounting surface (12) that delimits the rotor (4) in the axial direction (8), and the ring structure (10) exhibits a smaller coefficient of sliding friction than the inner mounting surface (12) that delimits the rotor (4).
