Abstract

Un embrayage qui comporte deux demi-sections (10, 12) et trois éléments de couplage intermédiaires (14, 16, 18), qui sont disposés de façon à se déplacer librement entre les demi-sections (10, 12), tournant les unes par rapport aux autres autour d'axes communs, et dont chacun est relié par une pièce de guidage (20, 22, 24) à la première demi-section (10) et par une autre pièce de guidage (26, 28, 30) à la seconde demi-section (12). Afin de réduire les forces centripètes sur les pièces de guidage (36, 38) et ainsi permettre à l'embrayage d'être utilisé pour des vitesses de rotation plus élevées, les paliers (36) sont maintenus, sous la forme de paliers de caoutchouc, dans les demi-sections (10, 12) ou éléments de raccordement intermédiaires (14, 16, 18). Les pièces de guidage (20, 22, 24, 30) sont reliées par des pivots (32, 34) et revêtent la forme de bandes plates (48, 50).
