Abstract
(EN)
A clutch device (1) for controlling transmission of torque between a first rotating body (21) and a second rotating body (23) each capable of rotating about an axis is provided with: a cam plate (35) provided with a first cam surface (35c) and capable of rotating about the axis with respect to the second rotating body (23); a pilot clutch (29) linked to the cam plate (35) so as to brake the cam plate (35) in the circumferential direction with respect to the first rotating body (21); a pressure plate (39) which is provided with a second cam surface (39c) facing the first cam surface (35c) in the axial direction and can rotate together with the second rotating body (23) and move in the axial direction; a plurality of rolling bodies (41) for rolling in accordance with differential motion of the cam plate (35) with respect to the pressure plate (39), the rolling bodies (41) being interposed between the cam plate (35) and the pressure plate (39); a support (37) which forms a ring about the axis and rotatably supports each of the plurality of rolling bodies (41) and restricts rolling thereof, the support (37) being friction-fitted with the second rotating body (23) so as to generate resistance against movement in the rotation direction; and a friction clutch (25) for transmitting torque between the first rotating body (21) and the second rotating body (23) when axially pressed to the pressure plate (39).

La présente invention concerne un dispositif d'embrayage (1) pour commander la transmission d'un couple entre un premier corps rotatif (21) et un second corps rotatif (23) capables chacun de se mettre en rotation autour d'un axe, ledit dispositif d'embrayage comprenant : une plaque de came (35) pourvue d'une première surface de came (35c) et apte à se mettre en rotation autour de l'axe par rapport au second corps rotatif (23) ; un embrayage pilote (29) relié à la plaque de came (35) de manière à freiner la plaque de came (35) dans la direction circonférentielle par rapport au premier corps rotatif (21) ; une plaque de pression (39) qui est pourvue d'une seconde surface de came (39c) faisant face à la première surface de came (35c) dans la direction axiale et qui peut se mettre en rotation conjointement avec le second corps rotatif (23) et se déplacer dans la direction axiale ; une pluralité de corps de roulement (41) pour rouler conformément à un mouvement différentiel de la plaque de came (35) par rapport à la plaque de pression (39), les corps de roulement (41) étant intercalés entre la plaque de came (35) et la plaque de pression (39) ; un support (37) qui forme un anneau autour de l'axe et supporte de manière rotative chacun de la pluralité de corps de roulement (41) et limite leur roulement, le support (37) étant monté à ajustement serré avec le second corps rotatif (23) de façon à générer une résistance contre un mouvement dans la direction de rotation ; et un embrayage à friction (25) pour transmettre un couple entre le premier corps rotatif (21) et le second corps rotatif (23) lorsqu'il est pressé axialement sur la plaque de pression (39).
