Abstract

La présente invention concerne un détecteur de couple pour bicyclette électrique qui est léger, économique et facile à assembler ; et est configuré sans utilisation de composants spécialisés ou lourds. Un roulement (26) et un autre roulement constituant une paire disposée latéralement pour supporter en rotation un vilebrequin (7a) sont disposés à l'intérieur d'une partie support (20) fixée à un cadre. Un élément de support de capteur (23) ayant une partie de déformation élastique (23a) est disposé entre la partie support (20) et le roulement (26), lequel est disposé d'un côté où un pignon d'entraînement transversal (13) est fixé. Un capteur de détection de contrainte élastiquement déformable (24) est fixé à la partie de déformation élastique (23a), qui vient en butée contre le roulement (26) par l'arrière.
