Thanks to the electrification of the powertrain, innovation in the automotive industry is happening faster than ever. Short time to market for electric vehicles (EVs) and hybrid vehicles (HEVs) is one key to be successful for OEMs and tier 1 suppliers.
The Schaeffler Group is developing electric axle systems for hybrid- and fully electric cars. When Schaeffler Technologies needed to understand and optimize oil distribution in their electric axle gearbox, they chose PreonLab, our Computational Fluid Dynamics (CFD) simulation tool. PreonLab supports Schaeffler in analyzing and optimizing the oil distribution in its gearboxes. Gearbox lubrication and cooling poses a major challenge for the developers of e-axle systems.
Different lubrication concepts have a big impact on the cooling, weight and efficiency of the system. It’s vital that the best concept is developed for the right applications, and that this decision is made as early in the development process as possible. With its meshless approach and extremely fast solver, PreonLab enables a short pre-processing, no meshing and a superior simulation time.
