Title (EN) CLUTCH UNIT
(FR) UNITÉ D'EMBRAYAGE
(JA) クラッチユニット
Abstract:
(EN) The present invention comprises a lever-side clutch part (11) that controls transmission and interruption of a rotary torque inputted by a lever operation, and a brake-side clutch part (12) that transmits a rotary torque from the lever-side clutch part (11) to the output side and interrupts a rotary torque inputted reversely from the output side, wherein the brake-side clutch part (12) is provided with: a cover (24), rotation of which is restricted; an output shaft (22) through which rotation is outputted; an inner ring (15) which is disposed between the cover (24) and the output shaft (22), and to which a rotary torque from the lever-side clutch part (11) is inputted; and a cylindrical roller (27) which controls both interruption of rotary torque from the output shaft (22) and transmission of rotary torque from the inner ring (15) in response to engagement and disengagement between the outer ring (23) and the output shaft (22), wherein the inner ring (15), which is coupled to the output shaft (22) in such a manner as to be able to transmit a torque, is additionally provided with a slide gear (32) which meshes with the cover (24) during interruption of rotary torque, and which is disengaged from meshing with the cover (24) during transmission of rotary torque.
(FR) La présente invention comprend une partie embrayage (11) côté levier qui commande la transmission et l'interruption d'un couple rotatif appliqué par une opération du levier, et une partie embrayage (12) côté frein qui transmet un couple de rotation de la partie embrayage (11) côté levier au côté sortie et qui interrompt un couple de rotation appliqué en sens inverse du côté sortie, la partie embrayage (12) côté frein étant pourvue : d'un couvercle (24), dont la rotation est limitée ; d'un arbre (22) de sortie à travers lequel la rotation est fournie ; d'une bague (15) interne qui est disposée entre le couvercle (24) et l'arbre (22) de sortie, et à laquelle un couple de rotation provenant de la partie embrayage (11) côté levier est fourni ; d'un rouleau (27) cylindrique qui commande à la fois l'interruption du couple de rotation depuis l'arbre (22) de sortie et la transmission d'un couple de rotation provenant de la bague (15) interne en réponse à une mise en prise et à une libération entre la bague (23) externe et l'arbre (22) de sortie, la bague (15) interne, qui est accouplée à l'arbre (22) de sortie de manière à pouvoir transmettre un couple, est en outre pourvue d'un engrenage (32) coulissant qui s'engrène avec le couvercle (24) pendant l'interruption du couple de rotation et qui est libéré de l'engrènement avec le couvercle (24) pendant la transmission d'un couple de rotation.
(JA) レバー操作により入力される回転トルクの伝達および遮断を制御するレバー側クラッチ部(11)と、レバー側クラッチ部(11)からの回転トルクを出力側へ伝達すると共に、出力側から逆入力される回転トルクを遮断するブレーキ側クラッチ部(12)とからなり、ブレーキ側クラッチ部(12)は、回転が拘束されたカバー(24)と、回転が出力される出力軸(22)と、カバー(24)と出力軸(22)との間に配置され、レバー側クラッチ部(11)からの回転トルクが入力される内輪(15)と、外輪(23)と出力軸(22)との間での係合および離脱により、出力軸(22)からの回転トルクの遮断と内輪(15)からの回転トルクの伝達とを制御する円筒ころ(27)とを備え、出力軸(22)にトルク伝達可能に連結された内輪(15)に、回転トルクの遮断時にカバー(24)と噛合し、回転トルクの伝達時にカバー(24)との噛合状態が解除されるスライドギヤ(32)を付設する。
