Thereby, the first clutch case 21 and the second clutch case 22 are integrally rotatable. Further, in the second clutch case 22, the fan 40 is bolted to the peripheral flange portion 22a, and a case-side labyrinth groove 22c is formed at a position facing the disc-side labyrinth groove 12c of the inner side surface 22b.

It is stored once. And the amplitude energy stored in this viscous fluid etc. is released at the time of the reverse amplitude which vibrates in the reverse direction. That is, the viscous fluid and the elastic support member 53 in the oil chamber 50 exhibit the function of the attenuator, and the vibration of the first clutch case 21 can be suppressed.

  • the oil chamber 50C is formed along the outer periphery of the drive disk 12.

Abstract

L'invention fournit un embrayage de ventilateur qui permet d'inhiber l'augmentation de vibrations lors de la production d'une entrée de vibrations provenant d'un moteur. Plus précisément, l'invention concerne un embrayage de ventilateur (1) qui est équipé : d'un axe d'entraînement (11) entraîné en rotation par un moteur ; d'un disque d'entraînement (12) fixé sur l'axe d'entraînement (11) ; d'un premier et d'un second carter d'embrayage (21, 22) qui sont supportés en rotation libre sur l'axe d'entraînement (11), et auxquels la rotation du disque d'entraînement (12) est transmise par l'intermédiaire d'un fluide visqueux ; et d'un ventilateur (40) installé sur le second carter d'embrayage (22). Le premier et le second carter d'embrayage (21, 22) possèdent un caisson de transmission de couple (24a) dans lequel est disposé le disque d'entraînement (12), un caisson d'huile (24b) compartimenté vis-à-vis de la chambre de transmission de couple (24a) par l'intermédiaire d'une paroi de séparation (24), et une chambre d'huile (50) communiquant avec le caisson d'huile (24b). Enfin, une masse (52) est configurée de manière à être supportée par l'intermédiaire d'un élément de support élastique, dans la partie interne de la chambre d'huile (50).
