Abstract

La présente invention concerne un limiteur de couple qui comprend : un premier élément de transmission qui est fait de métal et auquel le couple provenant d'une source d'entraînement est transmis ; et un second élément de transmission qui est fait de métal et qui est pressé contre le premier élément de transmission, les premier et second éléments de transmission étant amenés à coulisser l'un par rapport à l'autre contre une force de frottement entre les premier et second éléments de transmission lorsque le couple provenant de la source d'entraînement devient trop grand, et une poudre métallique étant disposée entre les premier et second éléments de transmission. Ainsi, il est possible d'assurer un bon coefficient de frottement dans l'état initial entre les premier et second éléments de transmission qui sont prévus dans le limiteur de couple, et également de supprimer l'usure irrégulière et de réduire une augmentation du coût des premier et second éléments de transmission.
