HYBRID TRANSMISSION WITH AN ADDITIONAL ELECTRIC MACHINE

摘要

A hybrid transmission for a motor vehicle provided with a heat engine and an electric driving machine includes two concentric primary shafts and a first coupling between the two primary shafts able to occupy at least three positions in which the heat engine is uncoupled from the kinematic chain connecting the electric driving machine to the wheels, the heat engine drives the wheels with or without extra contribution from the electric driving machine, and the heat engine and the electric driving machine are coupled so as to add their torques toward the wheels. The transmission also includes a secondary shaft connected to the wheels of the vehicle and supporting a second coupling to connect either of the two secondary pinions on the shaft. The transmission also includes an additional shaft connected to an additional electric machine to supply an engine torque or a resistive torque to the transmission.
