Electric axles are a key element of our electric mobility strategy,” says Matthias Zink, CEO Automotive Technologies at Schaeffler AG. Until now, up to three drive components were assembled in one compact unit. With the so-called 4in1 electric axle, Schaeffler is now going one step further by integrating the thermal management system as well as the electric motor, power electronics, and transmission into the axle drive. This makes the axle drive more compact and lighter and ensures greater comfort. A particularly efficient thermal management system also ensures that a car travels further on one battery charge and charges faster.
An intelligent control system ensures that excess heat is efficiently dissipated from the power electronics and electric motor and that it is used in the interior of the vehicle.
