发明名称 Electric axle for a vehicle
摘要 An electric axle for a vehicle, including an electric motor, a reduction gear section, a torque-distributing differential and two output shafts, where the electric motor, the torque-distributing differential and the two output shafts are disposed coaxially with a main transmission axis, and where the electric motor generates a drive torque which is reduced by the reduction gear section and distributed to the two output shafts via the torque-distributing differential, and further including a differential mechanism. The torque-distributing differential is designed as a planetary differential, and the differential mechanism is operatively connected to the torque-distributing differential via a shaft means disposed coaxially with the main transmission axis. The differential mechanism makes it possible to vary a speed difference and/or torque difference between the output shafts.

主权项 1. An electric axle for a vehicle comprising: an electric motor; a reduction gear section; a torque-distributing differential; and two output shafts, the electric motor, the torque-distributing differential and the two output shafts being disposed coaxially with a main transmission axis, the electric motor generating a drive torque which is reduced by the reduction gear section and distributed to the two output shafts via the torque-distributing differential, a differential mechanism, and wherein the torque-distributing differential is designed as a planetary differential, and the differential mechanism is operatively connected to the torque-distributing differential via a shaft assembly disposed coaxially with the main transmission axis, and wherein the differential mechanism can vary a speed difference or torque difference between the output shafts; wherein the differential mechanism is positioned outside the space between free ends of the output shafts in the axial direction with respect to the main transmission axis.
