Modern drivetrain architectures that include e-Axles and hybrid transmissions require filtration solutions with higher demands to protect all system components and to reduce the energy consumption. MANN+HUMMEL has developed a new generation of filters that are covering these demands. In this contribution it will be presented how these filters increase the degrees of freedom for the development of lubrication circuits of modern drivetrains significantly by offering an ultra-compact and flexible installation space, lowest differential pressure or highest filtration efficiencies. The new MANN+HUMMEL filter media portfolio MULTIGRADE O-eM provides a high system security with long lifetimes at low energy dissipations, which contributes to enlarge the range of e-drives and also to lower the CO2 emission. With MANN+HUMMEL’s numerical development tools filter media as well as filters can be adapted digitally to fast changing demands and challenging installation spaces. To multiply these advantages a new generation of pleated suction-side filters has been developed. With up to 60 percent more filter area the new concept uses the given installation space to a maximum. A drainage grid keeps the energy efficiency as large as possible and media performance at a maximum level over the whole filter life. Based on that, a MANN+HUMMEL oil management system with highest filtration capabilities will be presented that can deal with air bubbles, intelligent cooling function and integrated oil drying.
