Schaeffler presents new hybrid drive and e-axles
At the 11th Schaeffler colloquium the newly created e-mobility unit presented solutions for future electric and hybrid drive systems. They are based on a unified development platform, which was also first presented to the public.
The hybrid modules have a particularly compact design and have an integrated triple clutch. The hybrid modules by Schaeffler are known for their positioning between the combustion motor and the transmission in a P2 layout. The third generation of these modules the entire double clutch is fitted inside the electric motor, specifically the hollow space inside the rotor, allowing for an extra compact design.
Furthermore, Schaeffler is first presenting their dedicated hybrid transmissions, which are based on automated transmissions and have 2 electric and 6 mechanical gears. According to the manufacturer, this means that “The electric motor that operates parallel to the internal combustion engine is integrated into the transmission structure in such a way that it has two ratios available. The advantage: The electric motor can be operated very efficiently even at high driving speeds.” The DH-ST system performs at 220 kW and the WLTC consumption is around 4.5 liters per 100 km.
In order to underline the performance boost, Schaeffler compares their new electric axle drives to a 2011 version. The 2011 drive managed 60 kW with a weight of 90 kg, while the new axle drive manages 145 kW with 80 kg weight.
