Abstract
A power split hybrid wheel drive system of the present invention comprises a planetary gear train () coupled to the output shaft of a driving engine (). A primary motor or generator () is coupled to an output shaft of the planetary gear train () for receiving power therefrom, and a secondary motor or generator () is associated with each driven vehicle wheel () to provide an electrical power pathway. A mechanical differential gear train () is coupled between the output shaft of the planetary gear train () and each driven vehicle wheel; () to provide a mechanical power pathway, while a mechanical clutch () and brake system () is configured to regulate the mechanical power routed to the differential gear train (). A control system () is included to regulate the flow of electrical power between the primary motor () and secondary motors or generators ().
