The invention belongs to the technical field of internal transmissions, and particularly relates to a manual-automatic integrated internal variable speed hub and a bicycle. According to the manual-automatic integrated internal speed change hub, the transmission relation of the first-stage planetary gear mechanism or the second-stage planetary gear mechanism is only changed once when one gear is changed every time. In other words, in the process of rising from the first gear to the second gear, the second clutch structure is separated before the first clutch structure is connected, the second clutch structure is kept separated after the first clutch structure is connected, and in the process, only the transmission relation of the first-stage planetary gear mechanism is changed once; in other words, speed reduction transmission of the first-stage planetary gear mechanism is changed into invariable-speed transmission; and in the process that the second gear is lifted to the third gear, the first clutch structure is kept engaged, and the second sun gear is locked. In the gear shifting process, the transmission relation of the second-stage planetary gear mechanism is changed only once, the load of the driving mechanism can be effectively reduced, the gear shifting success rate is guaranteed, and power consumption is reduced.
本发明属于内变速器技术领域,特别涉及一种手自一体内变速花鼓及自行车。本手自一体内变速花鼓,每次变动一个挡位,只变更一次第一级行星齿轮机构或第二级行星齿轮机构的传动关系。即从一挡升到二挡过程中,第一离合结构接合之前,第二离合结构已经脱离,第一离合结构接合之后,第二离合结构保持脱离,这个过程中只变更了一次第一级行星齿轮机构的传动关系,即将第一级行星齿轮机构的减速传动变更为不变速传动;二挡升到三挡过程中,第一离合结构保持接合,第二太阳齿轮锁止。上述换挡过程中只变更了一次第二级行星齿轮机构的传动关系,能够有效降低驱动机构的负载,保证换挡成功率以及降低功耗。
