Abstract

L'invention concerne un embrayage normalement débrayé. Selon l'invention, il comprend un organe menant et rotatif 23 ayant un moyeu 26, un organe mené 51 rotatif autour du même axe que l'organe menant, un patin radialement contractile 80 entourant le moyeu, un moyen d'accouplement élastique 83 reliant le patin et l'organe mené pour une rotation à l'unisson, le moyen d'accouplement permettant une contraction radiale du patin autour du moyeu et maintenant normalement le premier hors d'engagement radial avec le second, un ressort hélicoïdal 50 télescopé sur le patin et ayant une extrémité fixée à l'organe mené pour tourner avec lui, un moyen 15, 16, 17, 20, 21, 29, 31 associé à l'organe menant pour forcer l'extrémité opposée du ressort à tourner avec lui afin de forcer ainsi le ressort à se serrer sur le patin et à le contracter radialement en engagement de serrage par friction avec le moyeu pour transmettre le couple du moyeu au patin, du patin au moyeu d'accouplement et du moyen d'accouplement à l'organe mené. L'invention s'applique notamment à l'industrie automobile.
