Abstract
A speed reduction assembly for an electric vehicle includes an electric machine configured to operate as a motor and as a generator. The electric machine includes an output shaft that is rotatable about a longitudinal axis at an output speed. The assembly also includes an output member coupled to the output shaft and rotatable about the longitudinal axis at a reduced speed. In addition, the assembly includes a pericyclic apparatus coupled to the output shaft and the output member to reduce the output speed of the output shaft to the reduced speed of the output member. A vehicle may include the speed reduction assembly in certain configurations. The vehicle includes a battery module and the electric machine is in electrical communication with the battery module to recharge the battery module when the electric machine operates as the generator.
