Abstract:
an electric axle drive system is provided, which comprises a motor (EM) and a transmission; the transmission comprises an input shaft (S1), a first intermediate shaft (S2) and a differential (DM); the input shaft (S1) establishes a continuous transmission connection with a rotor of the motor (EM); the first intermediate shaft (S2) establishes a transmission connection with the input shaft (S1), and the differential (DM) establishes a transmission connection with the first intermediate shaft (S2) via an internally meshing gear pair. As a consequence, the transmission ratio can be increased without increasing the overall packaging size of an electric axle drive system. A vehicle comprising the electric axle drive system is further provided.
