Abstract:
1. A travel system of a hybrid motor vehicle comprising: a thermal engine including a shaft, an electric machine including a rotor connected to at least one electric accumulator, a drive shaft controlled in rotation by at least one of the electric machine and the engine for rotating a motive axle of the vehicle, and a rotary speed variation device located between the drive shaft and a shaft of the engine, wherein the rotary speed variation device comprises at least two alternate transmission paths for rotary motion transmission to the motive axle with each path being controlled by at least one disengageable coupling; and wherein one of the at least two alternate transmission paths comprises the shaft of the engine, an engine shaft rotating speed reduction device and one of the at least one disengageable coupling for connection in rotation between the rotary speed variation device and the shaft of the engine; and the rotary speed variation device comprises a speed-reducer motion transmission device between the shaft of the engine and at least one of at least one camshaft and another rotary speed variation device disposed between the at least one camshaft and another of the at least one disengageable coupling.
