Further, when the motor generator 6 is used to regenerate the kinetic energy of the vehicle, the loss of the frictional energy on the engine side is prevented.
  • the friction facing portion 14 is connected to drive the engine, while the motor generator 6 is not supplied with power. Then, the torque from the engine is transmitted to the hub 13 via the damper mechanism 2 and the friction facing portion 14 and is transmitted to the output side shaft 51, and the vehicle travels only by the engine.
  • the hydraulic pressure does not act on the diaphragm spring 21, and only the urging force of the coin spring 34 acts on the diaphragm spring 21.
  • the release bearing 31 is biased toward the diaphragm spring 21 by the biasing force of the coil spring 34, there is no gap between the release bearing 31 and the diaphragm spring 21. For this reason, wear and impact noise of the release bearing 31 and the diaphragm spring 21 occur.
  • the pressing force by the coil spring 34 is a force that cannot move the lever portion of the diaphragm spring 21 to the engine side, the pressure plate 22 is pressed by the spring portion of the diaphragm spring 21. In this state, the friction facing portion 14 and the second flywheel 12 are in frictional engagement.
  • the length of the clutch housing can be shortened.

Abstract

La présente invention concerne un dispositif de transmission de couple destiné à transmettre le couple de sortie d'un moteur (100) à une transmission (101). Le dispositif de transmission de couple possède un organe latéral d'entrée connecté à un organe du côté du moteur (100), un arbre (51) connecté à un organe du côté de la transmission (101), un dispositif d'embrayage à sec doté d'un diaphragme annulaire (21) qui transmet ou interrompt le couple entre l'organe latéral d'entrée et l'arbre (51), un mécanisme de libération (5) qui appuie sur le bord périphérique interne du diaphragme annulaire (21) pour désengager l'embrayage à sec et un moteur-générateur qui transmet le couple entre lui-même et l'arbre (51). Le moteur-générateur (6) est installé sur le bord périphérique externe du mécanisme de libération (5), de façon coaxiale par rapport à ce dernier (5) et comporte un rotor (45) situé sur l'arbre (51) ainsi qu'un stator (46) faisant face au rotor (45).
