Title (EN) CONSTANT VELOCITY UNIVERSAL JOINT
(FR) JOINT HOMOCINÉTIQUE
(JA) 等速自在継手
Abstract:
(EN) The present invention comprises: an outer joint member 12; and an inner joint member 13 that transmits torque to and from the outer joint member 12 while allowing angular displacement via balls 14. A power transmission shaft 25 is coupled with the inner joint member 13 so as to be able to transmit torque. An attaching/detaching mechanism 33 that attaches/detaches the power transmission shaft 25 to/from the inner joint member 13 is provided between the inner joint member 13 and the power transmission shaft 25. The attaching/detaching mechanism 33 comprises: a cylindrical member 34 that is externally fitted onto the power transmission shaft 25; spherical bodies 35 that are accommodated in the cylindrical member 34 so as to be able to radially move; and an annular member 36 that is disposed so as to be able to axially move along an outer periphery of the cylindrical member 34. A locking pawl 42 is provided at an end of the annular member 36 on the inner joint member side. A locking groove 43 is provided at an end of the inner joint member 13 on the annular member side. The locking pawl 42 of the annular member 36 is fitted into the locking groove 43 of the inner joint member 13.
(FR) La présente invention comprend : un élément de joint externe (12) ; et un élément de joint interne (13) qui transmet un couple vers et depuis l'élément de joint externe (12) tout en permettant un déplacement angulaire par l'intermédiaire de billes (14). Un arbre de transmission de puissance (25) est couplé à l'élément de joint interne (13) de façon à pouvoir transmettre un couple. Un mécanisme de fixation/détachement (33) qui fixe/détache l'arbre de transmission de puissance (25) à/de l'élément de joint interne (13) est disposé entre l'élément de joint interne (13) et l'arbre de transmission de puissance (25). Le mécanisme de fixation/détachement (33) comprend : un élément cylindrique (34) qui est ajusté à l'extérieur sur l'arbre de transmission de puissance (25) ; des corps sphériques (35) qui sont logés dans l'élément cylindrique (34) de façon à pouvoir se déplacer radialement ; et un élément annulaire (36) qui est disposé de façon à pouvoir se déplacer axialement le long d'une périphérie externe de l'élément cylindrique (34). Un cliquet de verrouillage (42) est prévu au niveau d'une extrémité de l'élément annulaire (36) sur le côté élément de joint interne. Une rainure de verrouillage (43) est prévue au niveau d'une extrémité de l'élément de joint interne (13) sur le côté élément annulaire. Le cliquet de verrouillage (42) de l'élément annulaire (36) est ajusté dans la rainure de verrouillage (43) de l'élément de joint interne (13).
(JA) 外側継手部材12と、外側継手部材12との間でボール14を介して角度変位を許容しながらトルクを伝達する内側継手部材13とを備え、内側継手部材13に動力伝達軸25をトルク伝達可能に結合させ、内側継手部材13と動力伝達軸25との間に、内側継手部材13に対して動力伝達軸25を着脱する脱着機構33を設け、脱着機構33は、動力伝達軸25に外挿された筒状部材34と、筒状部材34に径方向移動可能に収容された球体35と、筒状部材34の外周に軸方向移動可能に配置された環状部材36とを備え、環状部材36の内側継手部材側端部に係止爪42を設けると共に、内側継手部材13の環状部材側端部に係止溝43を設け、環状部材36の係止爪42を内側継手部材13の係止溝43に嵌合させる。
