WHEEL DRIVING ASSEMBLY

摘要

The invention relates to a driving assembly comprising a wheel comprising a wheel shaft and driving means which when operative exert a driving moment on the wheel shaft, wherein a drive ratio, being the arm of the driving moment divided by the size of the wheel's radius, is larger than 0.57. This results in an improved efficiency. In addition to an improved efficiency of the motor itself this results in the additional effects described above as a result of which relatively considerable larger improvements of efficiency occur than might have been expected from the improvements of the efficiency of the motor alone.
