Abstract
An electromechanical module for a four wheeled vehicle 15, wherein said electromechanical module comprises two electric motors 2 and 3 each adapted to be mechanically coupled to a corresponding one of the two wheels 4 and 5 disposed on a common axle of the vehicle. Moreover, said electromechanical module comprises a control unit 8, two power electronic units 6 and 7 and electrical connections 8a, 8b, 6a and 7a to electrically connect the control unit 8 to each of said power electronic units 6 and 7 as well as to connect each of said power electronic units 6 and 7 to a corresponding one of said two electric motors 2 and 3. The electromechanical module according to the present invention allows transfer of electrical power between said two electric motors 2 and 3, thus allowing mechanical torque to be transferred between said two wheels 4 and 5, resulting in the traction capability and the driving performance of the vehicle being improved.
