According to the bicycle middle-mounted fixed shaft gear transmission column type transmission, the structural advantages of a parallel shaft gear transmission and the structural advantages of a planetary gear transmission are optimally combined, on the basis of the parallel shaft gear transmission, a crank main shaft serves as a center shaft, and the number of transition gear shaft assembly bodies is increased from one to several. The crank main shaft is arranged on the base and arranged along the concentric circle of the periphery of the crank main shaft to form a planetary structure, a control cam shaft assembly is arranged on the peripheral axis parallel to the crank main shaft, the crank main shaft is also an assembly, the left end of the crank main shaft is an input side, the right end of the crank main shaft is an output side, and the periphery of one section of the output side is concentrically sleeved with an output sleeve assembly.

    自行车中置固定轴齿轮传动柱式变速器,将平行轴齿轮变速器的结构优势与行星齿轮变速器的结构优势进行优化组合,在平行轴齿轮变速器的基础上,以曲柄主轴为中心轴,将过渡齿轮轴装配体由一只增加为数只,并沿曲柄主轴外周的同心圆布置,形成行星结构,并在平行于曲柄主轴的外周轴线上设置控制凸轮轴装配体,曲柄主轴也是一装配体,曲柄主轴左端是输入侧,右端为输出侧,在其输出侧一段的外周与其同心的套装有输出套装配体。
