Title (EN) TORQUE TRANSMISSION DEVICE
(FR) DISPOSITIF DE TRANSMISSION DE COUPLE
Abstract:
(EN) The invention relates to a torque transmission device (1) comprising a torque input element (5) intended to be coupled to a crankshaft of an engine, a torque output element (8) intended to be coupled to an input shaft of a gearbox, and shock absorption means (13, 17) mounted between the torque input element (5) and the torque output element (8), the torque output element (8) being able to pivot in relation to the torque input element (5) around an axis (X), against a resisting torque exerted by the shock absorption means (13, 17), the shock absorption means comprising at least one elastic blade (17) that can be elastically and radially held on a supporting body (13), and the elastic blade (17) being able to bend during the rotation of the torque input element (5) in relation to the torque output element (8). The device further comprises clutch means (20, 18) mounted between the torque input element (5) and the torque output element (8) and is characterised in that the supporting body is carried by the torque input element.
(FR) L'invention concerne un dispositif de transmission de couple (1) comportant un élément d'entrée de couple (5) destiné à être couplé à un vilebrequin d'un moteur, un élément de sortie de couple (8) destiné à être couplé à un arbre d'entrée d'une boîte de vitesses, des moyens d'amortissement(13, 17) montés entre l'élément d'entrée de couple (5) et l'élément de sortie de couple (8), l'élément de sortie de couple (8) étant apte à pivoter par rapport à l'élément d'entrée de couple (5) autour d'un axe (X), à l'encontre d'un couple résistant exercé par les moyens d'amortissement (13, 17), les moyens d'amortissement comportant au moins une lame élastique (17) apte à être maintenue élastiquement et radialement en appui sur un organe d'appui (13), la lame élastique (17) étant apte à fléchir lors de la rotation de l'élément d'entrée de couple (5) par rapport à l'élément de sortie de couple (8), le dispositif comportant en outre des moyens d'embrayage (20, 18) montés entre l'élément d'entrée de couple (5) et l'élément de sortie de couple (8), caractérisé en ce que l'organe d'appui est porté par l'élément d'entrée de couple.
