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. The manual and automatic integrated internal variable speed hub comprises a mandrel, a transmission mechanism, a driving mechanism, a control mechanism, an input piece and an output piece, the driving mechanism drives the transmission mechanism to rotate to a specific angle in a manual and/or automatic mode, the transmission relation of all components in the transmission mechanism is changed, and the transmission ratio of the transmission mechanism is changed. The manual-automatic integrated internal speed change hub has two modes of manual speed change and automatic speed change, in the manual speed change mode, a rider can freely change gears according to actual road conditions, and the riding flexibility is improved. And the gears are automatically changed according to a program in the automatic speed changing mode, so that the riding comfort is improved. The gear shifting mode is achieved through the electric drive control mechanism, compared with traditional pull wire gear shifting, the electric drive gear shifting mode does not have gear shifting resistance, the hand feeling is better, gear shifting is more accurate, and manual maintenance is not needed after long-time operation.
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包括芯轴、传动机构、驱动机构、操纵机构、输入件和输出件,驱动机构通过手动和/或自动的方式驱动传动机构转动到特定角度,改变传动机构中各部件的传动关系,实现传动机构变更传动比。本发明的手自一体内变速花鼓,具有手动变速和自动变速两种方式,在手动变速模式下,在骑行者既可以根据实际路况自由变更挡位,提高骑行的灵活性。在自动变速模式下按照程序自动变更挡位,提高骑行的舒适性。换挡的方式是通过电力驱动操纵机构实现的,相较于传统的拉线换挡,电力驱动换挡方式不存在换挡阻力,手感更好,挡位切换更精准,长时间运行不需要人工维护。
