A fluted disc type axial transmission power device without changing a bottom bracket of a bicycle comprises a power mechanism, a crankset and a plurality of stages of planetary gear sets, and is characterized in that the crankset comprises a fixed part and a rotating part, and a bearing is arranged between the fixed part and the rotating part for connection, so that the rotating part rotates on the fixed part; the fixing part is installed on one side of a five-way pipe of a bicycle, a cavity is formed in the fixing part, and an arc-shaped inner groove is formed in one side of the cavity. The rotating part is provided with a support flange, and the support flange is provided with a bearing connected with a bicycle middle shaft. The power mechanism is of a disc type driving structure, the installation process is simplified, high torque density is easy to achieve, the original bicycle structure does not need to be changed, an inner groove and a stator are of an incomplete annular structure, a vacancy is reserved for a frame of the bicycle, the situation that the overall structure of the power device is too large after installation is avoided, and the influence on the ergonomic design structure of the original bicycle is reduced; riding stress is scientific, the risk that a user is injured is reduced, and meanwhile electric power is provided.

    一种不改变自行车五通的齿盘式轴向传动动力装置,包括动力机构、牙盘和若干级行星齿轮组,其特征在于,所述牙盘包括固定部和转动部,所述固定部与转动部之间设有轴承连接,使转动部在固定部上旋转;所述固定部安装在自行车的五通管上的一侧,固定部的内部为腔室,在腔室的一侧设有弧形的内槽;所述转动部设有支架法兰,支架法兰设置轴承与自行车中轴连接;动力机构采用盘式驱动结构,简化安装过程,易于实现高扭矩密度,不需要改变原车结构,内槽和定子采用非完整的圆环状结构,为自行车的车架留出空位,避免安装之后动力装置的整体结构过于臃肿,减少对原车的人体工学设计结构的影响,使骑行受力科学,减少使用者受伤的风险,同时提供电动助力。
