Title (EN) MECHANICAL DEVICE FOR THE TRANSMISSION OF A FORCE WITH A THRESHOLD
(FR) DISPOSITIF MÉCANIQUE DE TRANSMISSION D'EFFORT À SEUIL
Abstract: front page image
(EN)The invention relates to a mechanical device for the transmission of a force with a threshold, including: a first element (1; 101) and a second element (2; 102) mounted such that they rotate in relation to one another about an axis of rotation (X), and a transmission member (10; 110) which is disposed between the aforementioned two elements and which secures the two elements to one another in rotation when a torque is applied to one of the elements so that said torque can be transmitted from one of the elements to the other, up to a threshold torque above which the two elements can rotate against a resistive torque equal to the threshold torque. According to the invention, the transmission member includes: at least a first friction disk (11; 111) rotatably fixed to the first element and a second friction disk (12; 112) opposite the first disk; a bearing member (13; 113) which can move axially such that, under the action of a press member, it can press the disks together and against a bearing plate (15; 115) of the first element; and rotation driving means (20, 21; 120, 121) disposed between the bearing member and the second element, which are provided to generate the axial movement of the bearing member against the spring member during a rotation.
(FR)L'invention est relative à un dispositif mécanique de transmission d'effort à seuil, comportant un premier élément (1;101) et un deuxième élément (2; 102) montés tournants relativement l'un à l'autre selon un axe de rotation (X), et entre lesquels est interposé un organe transmetteur (10; 110) qui solidarise les deux éléments en rotation lorsqu'un couple est imposé à l'un des éléments pour transmettre ce couple de l'un à l'autre des éléments, jusqu'à un couple seuil au-delà duquel les deux éléments deviennent mobiles en rotation à l'encontre d'un couple résistant égal au couple seuil. Selon l'invention, l'organe transmetteur comporte: - au moins un premier disque de friction (11; 111) solidaire en rotation du premier élément et un deuxième disque de friction (12; 112) en regard du premier disque; - un organe d'appui (13; 113) mobile axialement pour, sous l'action d'un organe presseur, presser les disques entre eux et contre un plateau d'appui (15; 115) du premier élément; - des moyens d'entraînement en rotation (20, 21; 120, 121) interposés entre l'organe d'appui et le deuxième élément qui sont agencés pour provoquer un déplacement axial de l'organe d'appui à l'encontre de l'organe ressort lors d'une rotation.
