Double Differential for Electric Vehicle and Hybrid Transmissions — Sophisticated Simplicity

The fascination with the automotive differential has led to the idea to build a second differential unit around a first center unit. Both units have the same axes around which they rotate at different speeds. The potential of double differentials as ultrahigh reduction speed reducers is significant. Only the tooth count of the gears in the outer differential unit must be changed in order to achieve ratios between 5 and 80 without a noticeable change in the transmission size.
