Abstract:
A device for transmitting movement to a fan for cooling a coolant in a motor vehicle, comprising:movement generating means on which the fan is mounted by means of an idle support; a first electromagnetic clutch, engagement of which causes rotation of the fan at a speed equal to that of the movement generating means; a second clutch, engagement and disengagement of which causes rotation of the fan at a speed less than that of the movement generating means or at zero speed, said second clutch having a rotor; means for engaging and disengaging the second clutch and including an actuating element coaxially displaceable in two opposite directions with respect to the movement generating means, but idle upon rotation of the movement generating means; and coupling elements which are coaxially locked in rotation with the movement generating means and connected to said displacement actuating element, said coupling elements enabling engagement and disengagement with the rotor of the said second clutch.
