Abstract:
(EN) Provided is a transmission which eliminates torque loss during gear shift and with which the processing of components can be simplified. When an axial force is generated in a protrusion (105) due to a guide portion (82) that is inclined relative to the axial direction, a clutch ring (90) separates from a transmission gear in the axial direction by the same amount as the axial length of the guide portion (82). An axial force is generated in the protrusion (105) by means of a first portion (77) during gear shift from a low gear to a high gear, and when a low-speed transmission gear and the clutch ring (90) separate from each other, a high-speed transmission gear and the clutch ring (90) interlock. Since the guide portion (82) can be formed in a second wall (75) when providing a groove portion (73), an increase in the processing workload required to provide the guide portion (82) can be suppressed, and there is no need for processing to provide a slope in the clutch ring (90).
(FR) L'invention concerne une transmission qui élimine une perte de couple pendant un changement de vitesse et avec laquelle le traitement d'éléments peut être simplifié. Lorsqu'une force axiale est générée dans une protubérance (105) due à une partie de guidage (82) qui est inclinée par rapport à la direction axiale, une bague de synchroniseur (90) se sépare d'un engrenage de transmission dans la direction axiale de la même longueur que la longueur axiale de la partie de guidage (82). Une force axiale est générée dans la protubérance (105) au moyen d'une première partie (77) pendant un changement de vitesse d'une vitesse basse à une vitesse élevée et, lorsqu'un engrenage de transmission à basse vitesse et la bague de synchroniseur (90) se séparent l'un de l'autre, un engrenage de transmission à grande vitesse et la bague de synchroniseur (90) s'emboîtent. Étant donné que la partie de guidage (82) peut être formée dans une seconde paroi (75) lors de la fourniture d'une partie de rainure (73), une augmentation de charge de traitement requise pour fournir la partie de guidage (82) peut être supprimée, et il n'est pas nécessaire que le traitement fournisse une pente dans la bague de synchroniseur (90).
(JA) 変速時のトルク切れを解消しつつ、部品の加工を簡素化できる変速機を提供する。軸方向に対して傾くガイド部(82)により軸方向の力が凸部(105)に生じると、ガイド部(82)の軸方向の長さの分だけ変速ギヤから軸方向へクラッチリング(90)が離れる。低速段から高速段への変速時に第1部分(77)により軸方向の力が凸部(105)に生じ、低速段の変速ギヤとクラッチリング(90)とが分離するときに高速段の変速ギヤとクラッチリング(90)とが結合する。ガイド部(82)は溝部(73)を設けるときに第2壁(75)に形成できるので、ガイド部(82)を設けるために加工工数が増加することを抑制できると共に、クラッチリング(90)に斜面を設ける加工を不要にできる。
