The invention relates to a drive wheel traction chain for a hybrid vehicle comprising a heat engine and a hydraulic traction machine powered by hydraulic accumulators forming two power units that can be used to drive the drive wheels of the vehicle. The invention further comprises a recharge module including electricity storage batteries connected to an electric machine which drives a hydraulic recharge machine that powers the hydraulic accumulators, and a means for controlling the recharge module connected to the means for controlling the power units of the vehicle.

Traction chain for a hybrid vehicle

The invention relates to a power train for a hybrid vehicle, comprising two hydraulic machines () including variable displacement, both of which are connected to a hydraulic pressure accumulator () which stores energy, a first hydraulic machine () being permanently connected to an internai combustion traction engine (), and a second hydraulic machine () being connected, also permanently, to drive wheels () of the vehicle, characterized in that the two hydraulic machines () are also interconnected by a linking means () that can be engaged or disengaged.

Power train for a hybrid vehicle

The invention relates to a variable displacement hydraulic machine, in particular for a motor vehicle, said hydraulic machine comprising a rotating cylinder () including a series of axial pistons () connected to a first plate () axially located on one side of said cylinder within a substantially transverse plane, the slope of which can be controlled, so as to form a first controllable displacement for said machine, wherein said machine is characterized in that the cylinder () further comprises a second series of axial pistons () connected to a second plate (), the slope of which is also controllable, said plate being axially located, relative to the first plate (), on the other side of said cylinder so as to form a second controllable displacement for said machine.
