Claim Text:
1. A traction chain for the drive wheels of a hybrid vehicle, said traction train comprising: a heat engine and a hydraulic traction machine, the hydraulic traction machine connected to a high-pressure hydraulic accumulator and a low-pressure hydraulic accumulator, the heat engine structured and operable to drive wheels of the vehicle, and hydraulic traction machine structured and operable to displace fluid from the high-pressure hydraulic accumulator toward the low-pressure hydraulic accumulator such that the hydraulic traction machine works as a motor and furnishes mechanical power the drive wheels, and receive mechanical power from the drive wheels to work as a pump and recharge the high-pressure accumulator; a recharge module that includes an electric machine, electricity storage batteries connected to the electric machine, and a hydraulic recharge machine, the hydraulic recharge machine structured and operable to receive mechanical power from the electric machine to work as a pump and recharge the high-pressure and low-pressure accumulators, and consume hydraulic pressure from the high-pressure and low-pressure accumulators to deliver mechanical power to the electric machine, whereby the electric machine generates electricity to recharge the electricity storage batteries, wherein the hydraulic recharge machine includes: a means for controlling the recharge module connected to a means for controlling the heat engine and a hydraulic traction machine of the vehicle, wherein the recharge module is an independent subassembly that is mounted in the traction chain.
