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.

A mechanism for power between a driving shaft and first and second assemblies to be driven, said mechanism comprising a free wheel interposed between the driving shaft and a first assembly driving means for transmitting rotary movement of the driving shaft to the first assembly driving means, the free wheel comprising a free wheel driving member fixed to an end of the driving shaft and comprising an extension thereof, and a free wheel driven member driving the first assembly driving means, actuating means for shifting the free wheel from a rotation engagement state to a rotation disengagement state between the free wheel driving member and the free wheel driven member, mechanical connection means between the driving shaft and a second assembly driving means, wherein the mechanical connection means comprises a connection shaft constantly drivingly connected with both the driving shaft and the second assembly driving means, said connection shaft carrying a control member for controlling the engagement state of the free wheel, and said connection shaft being able to slide along its axis in response to said actuating means between a first axial position in which the control member places the free wheel in the rotation engagement state, and a second axial position in which the control member places the free wheel in its rotation disengagement state.
