Abstract
(EN)
The present invention provides a centrifugal clutch that, with a simple configuration, makes it possible to place a clutch shoe in contact with a second shaft member, suppress a decrease in transmission torque, reduce the overall size, and suppress an increase in manufacturing costs. A centrifugal clutch (200) is provided with a first shaft member (210), a second shaft member (220), and a clutch lever (213) that has a friction surface (215) capable of coming into contact with the second shaft member (220). Said elements are disposed such that μ>tanθ in a state in which the friction surface (215) and the second shaft member (220) are in contact, where θ is the angle formed by a line connecting the center of a connection pin (217) and a force point (216) of the friction surface (215) and a line connecting the center of the second shaft member (220) and the force point (216), and μ is the static friction coefficient when the friction surface (215) and the second shaft member (220) are in contact. The clutch lever (213) is connected to a pivot pin (218), and a clutch shoe (214) is pivotably connected to the pivot pin (218).

La présente invention concerne un embrayage centrifuge qui, avec une configuration simple, permet de placer un sabot d'embrayage en contact avec un second élément d'arbre, de supprimer une diminution du couple de transmission, de réduire la taille globale, et de supprimer une augmentation des coûts de fabrication. Un embrayage centrifuge (200) est pourvu d'un premier élément d'arbre (210), d'un second élément d'arbre (220), et d'un levier d'embrayage (213) qui a une surface de frottement (215) apte à entrer en contact avec le second élément d'arbre (220). Lesdits éléments sont disposés de telle sorte que μ>tanθ dans un état dans lequel la surface de frottement (215) et le second élément d'arbre (220) sont en contact, θ étant l'angle formé par une ligne reliant le centre d'une broche de raccordement (217) et un point d'application de force (216) de la surface de frottement (215) et une ligne reliant le centre du second élément d'arbre (220) et le point de force (216), et μ est le coefficient de frottement statique lorsque la surface de frottement (215) et le second élément d'arbre (220) sont en contact. Le levier d'embrayage (213) est relié à un pivot (218), et un sabot d'embrayage (214) est relié pivotant au pivot (218).
