Abstract
To ensure the power transmission between a driving shaft (42) and two assemblies to be driven, such as the rotor or rotors and the ancillary systems of a gyroplane, a mechanism is proposed, which has a connection shaft (48) constantly engaged on the driving shaft and on device (54) for riving the ancillary systems. An actuator (80) controls a translation of the connection shaft between a first position in which a free wheel (44), interposed between the driving shaft (42) and a device (46) for driving the rotor or rotors, occupies a rotation engagement state and a second position, in which the free wheel occupies a rotation disengagement state. This particularly simple mechanism can be switched from one state to the other, even during the rotation of the driving shaft.
