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. A particularly efficient thermal management system also ensures that a car travels further on one battery charge and charges faster.
| E-motor | Gearbox | Power electronics system | Thermal management |
|---|---|---|---|
| High-speed with up to 18,500 rpm Direct Slot Cooling | Highly efficient spur gearing design Combined actuator for parking lock and e-motor cooling | Highly efficient silicon carbide semiconductors Central control of propulsion and thermal management system | CO2 heat pump for efficient climatization of the vehicle |
For the electrification of medium-duty pick-up trucks, particularly for the North American market, Schaeffler is developing and will manufacture an electric beam axle. In the electric beam axle, the electric motor, transmission, power electronics, and the entire rear axle are connected to each other and supplied to the customer as a ready-to-fit unit. Axles like these are more than two meters wide.
