Abstract (en)
Device for transmitting the movement to a fan (1) for cooling the coolant in a motor vehicle, comprising: - movement generating means (3,101); - at least one friction clutch (100) formed by a first fixed electromagnet (132) and a second fixed electromagnet (133), a first armature (110) and a second armature (120), and a rotor (140) to which the fan (1) is constrained; - at least one eddy-current clutch (200); - a fixed support (21) on which the movement generating means (3) are mounted via a first bearing (11); wherein: - said first armature (110) is a driving element and is connected to the movement generating means (3), said rotor (140) is a driven element and is mounted idle on the support (21) via a second bearing (15); - the eddy-current clutch (200) comprises a driving part (203) connected to the movement generating means (3,101) and a driven part (202,201) integral with said second armature (120) of the friction clutch (100).
