Electric Traction For Automobiles - Comparison of Different Wheel-Hub Drives
Electric traction drives presently available on the market are analyzed and future developments are described. Two main classes of such drives are presented: centre drives (like presently known from hybrid cars) and wheel-hub drives (which are still in the research and development phase). The wheel-hub drives are investigated in detail. Two different concepts are regarded: High-speed drive with gear-box and low-speed direct drive.The advantages and disadvantages of both concepts are shown, resulting in the fact that most probably the low-speed direct drive performs better.
