Abstract
(EN)
Provided is a power transmission device that effectively uses a space that is obtained in conjunction with the arrangement of a first clutch member and a second clutch member, is capable of suppressing a feeling of abruptness during power transmission, and is capable of improving operability. The power transmission device has: the first clutch member 4a coupled to an output shaft 3; the second clutch member 4b having a driven-side clutch plate 7 attached thereto; and a back torque transmission cam that, when rotational force is input to the first clutch member 4a, can move the second clutch member 4b and press a drive-side clutch plate 6 and the driven-side clutch plate 7. The power transmission device also comprises a shock absorbing member 12 that: is interposed between the first clutch member 4a and the second clutch member 4b; and can permit movement of a linking member 9 and a pressure member 5 and apply impelling force, by compressing during a process in which the linking member 9 moves and the pressure member 5 moves from an inactive position towards an active position.

L'invention concerne un dispositif de transmission d'énergie qui utilise efficacement un espace qui est obtenu conjointement avec l'agencement d'un premier élément d'embrayage et d'un second élément d'embrayage, est susceptible de supprimer une sensation de caractère abrupt pendant la transmission d'énergie et est susceptible d'améliorer l'exploitabilité. Le dispositif de transmission d'énergie comprend : le premier élément d'embrayage (4a) couplé à un arbre de sortie (3) ; le second élément d'embrayage (4b) ayant une plaque d'embrayage côté entraîné (7) fixée à celui-ci ; et une came de transmission de couple arrière qui, lorsqu'une force de rotation est appliquée au premier élément d'embrayage (4a), peut déplacer le second élément d'embrayage (4b) et presser une plaque d'embrayage côté entraînement (6) et la plaque d'embrayage côté entraîné (7). Le dispositif de transmission d'énergie comprend également un élément d'absorption de choc (12) qui : est interposé entre le premier élément d'embrayage (4a) et le second élément d'embrayage (4b) ; et peut permettre le mouvement d'un élément de liaison (9) et d'un élément de pression (5) et appliquer une force de poussée, par compression au cours d'un processus dans lequel l'élément de liaison (9) se déplace et l'élément de pression (5) se déplace d'une position inactive vers une position active.
