Schaeffler introduces new high-voltage P2 hybrid module; up to 800 N·m; first production application in China in 2017
September 29, 2015
Schaeffler has developed a new P2 (parallel, two-clutch) high-voltage hybrid module—arranged between the internal combustion engine and transmission—that can transmit engine torques of up to 800 N·m (590 lb-ft) to the transmission without having to incorporate a commensurately expensive clutch.The new generation P2 hybrid module can be used in both medium- and very high-performance transmission concepts—e.g., from mild to plug-in hybrids.
The high-torque module distributes the flow of forces in an innovative way; the pathway of torque conveyance depends on its direction. Torques are transmitted to the crankshaft via a 300 N·m disconnect clutch, while traction torques from the internal combustion engine are transmitted to the transmission via a one-way clutch. The clutch can therefore have a compact design, even at high torques, with the corresponding advantages in terms of space utilization and cost. Schaeffler showcased the unit at the International Motor Show (IAA) in Frankfurt.

Consultancy looks to aggressive weight reduction in major powertrain components for CO2 savings; metal and polymer matrix composites
December 11, 2014
UK automotive engineering consultancy Drive System Design (DSD) suggests the next breakthrough in CO2 emissions reduction will come from more aggressive weight reduction in major powertrain components. Analysis by the company has identified both near-term and medium-term solutions for the manufacture of items such as transmission casings using advanced composite materials, but favors modern hybrid materials such as metal and polymer matrix composites (MMCs and PMCs) over conventional carbon composite solutions.
Continual pressure on the automotive industry to reduce carbon emissions is leading to weight reduction initiatives throughout the vehicle. Currently, several of the heaviest individual components in the powertrain, such as the main casings for the transmission, are still metal (e.g., aluminum alloys, magnesium alloys and iron) castings despite the widespread use of lighter materials elsewhere on the vehicle.
