Schaeffler awarded International Grand Prix award for new P2 hybrid module

Schaeffler was awarded the International Grand Prix Award for Automotive Innovations in the OEM New Technologies category at the automotive aftermarket show EQUIP AUTO in Paris for the newly developed high-voltage P2 hybrid module (earlier post). Located between the internal combustion engine and transmission, the hybrid module can transmit internal-combustion torques of up to 800 N·m to the transmission.

Adaptable to a number of drive concepts on a modular basis, the new P2 hybrid module comprises an automatic disconnect clutch and an electric motor. The disconnect clutch is operated by an electromechanical concentric slave cylinder that directly engages the clutch mechanically via a ball screw drive without a hydraulic transmission path; this means that no additional space for actuators is required outside the module.

In order to efficiently transmit torques of up to 800 N·m without having to incorporate a commensurately expensive clutch, torque conveyance depends on its direction. A one-way clutch, for example, is used for transmitting traction torque in direction of transmission and electric motor, while torsional torque in the direction of the internal combustion engine is conveyed via the clutch. Even with high torque requirements, the clutch can therefore still have a compact design and the corresponding advantages in terms of the design envelope and cost.

This new hybrid module will go into volume production for the first time in China in 2017, in a version without a one-way clutch for internal-combustion torques of up to 250 N·m. Due to the fact that this hybrid module has considerably higher electrical power of 80 kW, it can be used as a plug-in hybrid, thereby providing up to 75% reductions in fuel consumption compared to similar vehicles with internal combustion engines.



How about use this concept to make an econobox with the same concept as the Koenigsegg Regera!
