The invention provides a transmission device of an electric bicycle. The transmission device comprises an outer rotor motor, a shaft type gear, a crankshaft and a single-section type speed reduction transmission assembly. The outer rotor motor comprises a stator assembly, a rotor assembly and a shell. The rotor assembly is arranged in the shell. The shaft-type gear comprises a joint part and a gear part, and the joint part is arranged on the shell. The single-section type speed reduction transmission assembly surrounds the crankshaft and comprises a transmission gear. A central axis of the shaft type gear and the central axis of the crankshaft are substantially parallel and non-coaxial, and the transmission gear is directly meshed with the gear part. Therefore, the transmission device of the electric bicycle is easy to assemble, low in cost and so on.

    本发明提供一种电动自行车的传动装置,其包含外转子马达、轴型齿轮、曲柄轴及单段式减速传动组件。外转子马达包含定子组件、转子组件及壳体。转子组件设置于壳体。轴型齿轮包含接合部及齿轮部,接合部设置于壳体。单段式减速传动组件环绕于曲柄轴上,单段式减速传动组件包含传动齿轮。其中,轴型齿轮的中心轴与曲柄轴的中心轴呈实质平行且非共轴,且传动齿轮直接啮合于齿轮部。藉此,本发明的电动自行车的传动装置具有组装简易、成本低等功效。
