Title (EN) CLUTCH DEVICE AND MOTOR UNIT USING SAID CLUTCH DEVICE
(FR) DISPOSITIF D'EMBRAYAGE ET UNITÉ DE MOTEUR UTILISANT LE DISPOSITIF D'EMBRAYAGE

Abstract:
(EN) The present invention pertains to a clutch device having an input disk (61), an output disk (62), and a biasing member (63) that presses the input disk (61) onto the output disk (62), wherein the rotational load applied to an output shaft (30) pulls the input disk (61) apart from the output disk (62) against the biasing force of the biasing member (63). Teeth (61a, 62a) are provided to respective facing surfaces of the input disk (61) and the output disk (62), said teeth (61a, 62a) overlapping in relation to the other surface and being able to disengage in the shaft direction. The teeth (61a, 62a) comprise recessed parts (1) and protruding parts (2), which are continuous in the radial direction and are arranged alternately in the circumferential direction. The recessed parts (1) and protruding parts (2) are formed so as to have a curved surface such that, while the height remains the same, the circumferential width (w) continuously expands in the outward radial direction. The present invention also pertains to a motor unit equipped with the clutch device. As a result, the present invention makes it possible to reduce deformation and damage to disengaging parts, and to improve durability.
(FR) La présente invention concerne un dispositif d'embrayage comportant un disque d'entrée (61), un disque de sortie (62), et un élément de sollicitation (63) qui presse le disque d'entrée (61) contre le disque de sortie (62), où la charge de rotation appliquée à un arbre de sortie (30) tire le disque d'entrée (61) pour le séparer du disque de sortie (62) contre la force de sollicitation de l'élément de sollicitation (63). Des dents (61a, 62a) sont situées sur des surfaces respectives se faisant face du disque d'entrée (61) et du disque de sortie (62), lesdites dents (61a, 62a) se chevauchant par rapport à l'autre surface et pouvant se dégager dans la direction d'arbre. Les dents (61a, 62a) comprennent des parties en creux (1) et des parties en saillie (2), qui sont continues dans la direction radiale et sont agencées en alternance dans la direction circonférentielle. Les parties en creux (1) et les parties en saillie (2) sont formées de manière à avoir une surface incurvée telle que, bien que la hauteur reste la même, la largeur circonférentielle (w) s'agrandit continuellement dans la direction radiale vers l'extérieur. La présente invention concerne également une unité de moteur équipée du dispositif d'embrayage. Par conséquent, la présente invention permet de réduire la déformation et la détérioration de pièces de débrayage, et d'améliorer la durabilité.
(JA) 本発明は、入力ディスク(61)と、出力ディスク(62)と、入力ディスク(61)を出力ディスク(62)に押し付ける付勢部材(63)とを備え、出力軸(30)に加わる回転負荷により入力ディスク(61)を付勢部材(63)の付勢力に抗して出力ディスク(62)から引き離すものであって、入力ディスク(61)及び出力ディスク(62)の各対向面には、他方の面に対し重なり合うとともに軸方向へ嵌脱可能な歯部(61a,62a)が設けられ、歯部(61a,62a)は、径方向へ連続する凹部(1)と凸部(2)を周方向へ交互に配設してなり、凹部(1)と凸部(2)の各々は、同じ高さに維持されたまま径外方向へゆくにしたがって連続的に周方向幅(w)が拡がる曲面状に形成されているクラッチ装置、及びこれを備えるモータユニットに関する。本発明は、これにより、嵌脱部分の変形や損傷などを軽減して耐久性を向上させることが可能となる。
