The embodiment of the invention discloses a driving and speed changing integrated rear-mounted device, and relates to the technical field of bicycles. The driving and speed changing integrated rear-mounted device comprises a hub, a flywheel, a main driving unit, an auxiliary driving unit, a first transmission mechanism and a second transmission mechanism. The main driving unit is connected with the first transmission mechanism, and the first transmission mechanism comprises a first planet carrier, a first planet wheel, a first sun wheel and a first transmission wheel. And the auxiliary drivingunit is connected with the second transmission mechanism, and the second transmission mechanism comprises a second planet carrier, a second planet wheel, a second sun wheel and a second transmissionwheel. The driving and speed changing integrated rear-mounted device can achieve a power-assisted driving function and a speed changing function at the same time, and is low in cost, light in weight,small in size and continuous in speed changing without blockage compared with a mode that a driving system and an external rear wheel speed changing system or an internal speed changing system are adopted in the prior art.

    本发明实施例公开了一种驱动与变速一体式后置装置,涉及自行车技术领域。所述驱动与变速一体式后置装置包括轮毂、飞轮、主驱动单元、辅助驱动单元、第一传动机构以及第二传动机构。所述主驱动单元与第一传动机构连接,所述第一传动机构包括第一行星架、第一行星轮、第一太阳轮以及第一传动轮。所述辅助驱动单元与第二传动机构连接,所述第二传动机构包括第二行星架、第二行星轮、第二太阳轮以及第二传动轮。本发明提出的驱动与变速一体式后置装置能够同时实现助力驱动和变速功能,相比于现有技术分别采用驱动加外挂后轮变速或内变速两套系统的方式,具有成本低、重量轻、体积小以及变速连续不卡顿的特点。
