A New Powertrain System for Electric Hybrid Vehicles

A new powertrain system was developed for electric vehicle driving application with adoption of one electric motor and one set of planetary gear set. With the control of fork, the sleeve of synchronizer can mesh two different parts on the left and right side; the system can provide pure electric driving, hybrid driving and regenerative braking operation modes to meet vehicle practical conditions. It can reduce both power train structure size and cost with fewer parts.
