The invention discloses a variable hub of an electric bicycle, and belongs to the technical field of hub motors, the variable hub comprises a mounting support shaft connected with a bicycle body, a pneumatic driving part, a hub body, a stator and a rotor, the hub body comprises a hub disc and a rim connected with the hub disc through a radial plate, the hub disc is arranged on the mounting support shaft through a support bearing, and the pneumatic driving part is arranged on the hub disc. And a high-torque transmission assembly and a direct-drive transmission assembly which are connected with the driving ring are arranged on the driving disc. The transmission mode of the hub can be flexibly adjusted according to riding habits and requirements, conversion between the direct-drive transmission assembly and the high-torque transmission assembly is achieved through movement of the pneumatic switching ring, and the effects of high transmission efficiency, one-way transmission and reverse locking are achieved under the action of the direct-drive transmission assembly; in the high-torque assembly transmission process, when a rotor drives riding, large-torque transmission can be achieved, the motor is suitable for different use environments, in the power generation process, rapid rotation of the rotor is achieved, and the power generation efficiency is remarkably improved.

    本发明公开了一种电动自行车的可变式轮毂,属于轮毂电机技术领域,包括与车体连接的安装支撑轴、气动驱动件、轮毂本体、定子和转子,轮毂本体包括轮毂盘和与轮毂盘通过辐板连接的轮辋,轮毂盘通过支撑轴承设置在安装支撑轴上,驱动盘上设置有与驱动环连接的高扭矩传动组件和直驱传动组件。本发明根据骑行习惯和需求可进行灵活调整轮毂的传动方式,通过气动切换环的移动,达到在直驱传动组件和高扭矩传动组件之间的转换,在直驱传动组件的作用下达到传动效率高,单向传动和反向锁定的效果,在进行高扭矩传动组件过程中,能在转子带动骑行时,达到大扭矩传动,适用不同的使用环境,在进行发电过程中,实现转子的快速转动,显著提高发电效率。
