The Modular Hybrid Transmission Kit from ZF

In view of legal requirements and measures for climate protection, fuel efficient vehicles have become increasingly important. Against this background, transmissions are a key factor for two main reasons: Energy consumption and emissions can be reduced by optimization of conventional transmissions. The "ideal" transmission has a potential of contributing to this goal by about 10%. Between 4 and 5% out of this 10% can realistically be achieved. Driveline electrification constitutes another necessary step for CO₂ savings. To this end, an ideal option is integrating the electric components into the transmission. In view of the uncertain market development for hybrid car demand, a modular approach to electrification in transmissions is essential. This article outlines the electrification approach.
