Abstract: The invention relates to a hybrid vehicle drive train comprising a heat engine (2) connected to a power distribution system (4) that distributes power over two paths, one path driving the driving wheels (22) of the vehicle via a mechanical transmission (14) and one path driving a hydraulic pump (10) that refills pressure accumulators (30, 32). The drive train (1) also comprises a hydraulic motor (24) which draws the fluid from the pressure accumulators in order to drive the driving wheels (22). The drive train is characterized in that it also includes an electric pump (34) which is connected to batteries (36), as well as to the pressure accumulators (30, 32) in order to refill said accumulators using power supplied by the batteries.
