Abstract

The present invention is a powertrain for a hybrid vehicle, comprising a driving and receiving machine (), a thermal engine () and engine shaft (), a speed variation device () including an engine epicyclic gear train () with a sun gear () and a crown () which are each connected to the engine shaft () by an engine controlled coupling () and to a fixed part () of the powertrain by a one-way automatic coupling (). A planet gear carrier () and a machine epicyclic gear train () are arranged on a shaft () substantially parallel to engine shaft (). The planet gear carrier comprises a sun gear (), a crown (), a planet gear carrier () and an epicyclic gear train controlled coupling (). The speed variation device () comprises a device () for connecting and disconnecting and electrical machine () with a machine epicyclic gear train ().
