Tahara, Y., Ogawa, K., Nonaka, N., Kimura, T. et al., "Development of Compact Electric Rear-Drive Unit," SAE Technical Paper 2016-01-1104, 2016, doi:10.4271/2016-01-1104.
We have developed an electric rear-drive unit to enable all-wheel drive (AWD) applications to the compact FF hybrid passenger vehicles. The development is intended to provide a compact and low cost unit with low fuel consumption. The unit newly introduces a two-axis gear train that enables a compact design, an induction motor and an ATF (automatic transmission fluid) stirring resistance restraining structure that contribute to lower fuel consumption. This paper presents the features and performance of the electric rear-drive unit.
