The invention relates to a tubular column with variable transmission ratio. The tubular column comprises a tubular column body, the tubular column body further comprises a first tubular column, a second tubular column, a third tubular column and a shifting assembly, the second tubular column is connected with the first tubular column through a spline and can move in the axial direction of the second tubular column relative to the first tubular column, a first gear set is arranged on the second tubular column, the first gear set comprises a plurality of gears with different diameters, the third tubular column is provided with a second gear set, the second gear set comprises a plurality of gears with different diameters, at least one gear in the second gear set is meshed with the gear in the first gear set, and the stirring assembly is used for stirring the second tubular column to move relative to the first tubular column, and thus the first gear set and the second gear set are switched from the first meshing state to the second meshing state. The tubular column with the variable transmission ratio is simple in structure, and the transmission ratio can be adjusted by switching different meshing states, so that the tubular column can be used under different road conditions.

    本申请涉及一种可变传动比管柱,其包括管柱本体,管柱本体还包括第一管柱、第二管柱、第三管柱以及拨动组件,第二管柱与第一管柱通过花键连接,且第二管柱可相对第一管柱沿第二管柱的轴向移动,第二管柱上设有第一齿轮组,第一齿轮组包括若干不同直径的齿轮,第三管柱上设有第二齿轮组,第二齿轮组包括若干不同直径的齿轮,且第二齿轮组中至少存在一个齿轮与第一齿轮组中的齿轮啮合,拨动组件用于拨动第二管柱相对第一管柱移动,以使得第一齿轮组和第二齿轮组从第一啮合状态切换至第二啮合状态。该可变传动比管柱结构简单,通过不同啮合状态的切换,可以实现传动比的调节,以满足不同路况下的使用。
