Transmission, vehicle, hybrid vehicle and unit for controlling and for switching between first and second power transmission processes consists of electric motor, a differential gearing mechanism and power coupling mechanism

摘要

A first power transmission process transmits an IC motor engine's (11) power output to a vehicle's drive shaft (15) via planetary gearing (18) linked to an electric motor (13). A second power transmission process transmits the motor engine's power output to the drive shaft via toothed gearing (16,17). A power transmission changeover device switches between first and second power transmission processes.
