System for driving at least one compressor that includes an input able to be connected to a belt secured to a rotary machine, an output able to be connected to the compressor, an epicyclic gear train the annulus gear of which forms a flywheel and the sun gear of which is connected to the output of the system, and a device allowing the configuration of the epicyclic gear train to be modified so that this gear train selectively adopts at least the following configurations: (i) a configuration in which the epicyclic gear train is coupled to the input of the system, (ii) a configuration in which the epicyclic gear train has no internal degree of freedom and in which the epicyclic gear train is uncoupled from the input of the system.

System for driving at least one compressor, notably a combustion engine supercharger compressor

The invention relates to a device for transmitting mechanical torque between a driving member and a driven member, in particular between a heat engine and an air compressor () for supplying power to the engine. Said transmission device includes at least one pulley (), for transmitting the torque between the driving member and the driven member, and a release means () controlling at least one of said pulleys () so as to enable the transmission of the torque between the driving member and the driven member when the latter are in an engaged state, or so as to restrict the transmission when the latter are in a disengaged state. The invention also relates to an air-compression system for supplying power to a heat engine, in particular for a motor vehicle, said system including a compressor () and a torque-transmitting device () enabling torque to be taken up on a belt () of the engine and said torque to be transmitted to the compressor, said transmission device () being capable of transmitting said torque at a first transmission ratio up to a certain engine speed threshold and of no longer transmitting said torque when said threshold is exceeded, or of transmitting said torque at a lower transmission ratio when the engine speed is above said threshold.
