Electrical axle

摘要

An electrical axle for a four wheeled road vehicle with an electrical propulsion motor arranged coaxially on the axle. A first planetary gear is connected to the electrical propulsion motor and to a first side of the axle. A second planetary gear is connected to the electrical propulsion motor and to a second side of the axle. The first and second planetary gears form a differential mechanism. A torque vectoring unit includes an electrical motor arranged coaxially on the axle for providing a change in torque distribution between the first side and the second side of the axle. The electrical motor of the torque vectoring unit is connected to the first and second planetary gears.
