The invention relates to a steering column with a crumple function. Comprising a pipe column, an aluminum cast pipe, a handle, a handle shaft and a support, the aluminum cast pipe and the support are arranged on the outer side of the aluminum cast pipe, the handle shaft penetrates through the support and the aluminum cast pipe to clamp the pipe column, the handle is arranged at one end of the handle shaft, the outer side of the pipe column is connected with an energy absorption device, and the lower side face of the energy absorption device is provided with first meshing teeth; a toothed stone is fixedly installed on the pin shaft, second meshing teeth are arranged on the toothed stone, the second meshing teeth are meshed with the first meshing teeth, the handle shaft is sleeved with a shifting block, and the shifting block drives the toothed stone to rotate. Most parts, such as the toothed stone and the shifting block, for realizing the crumple function are wrapped in the aluminum cast pipe, so that the influence (for example, dust on the surface of the parts, abnormal sound generated by entering foreign matters, clamping stagnation and the like) on the performance of the parts caused by excessive exposed external parts of the steering column assembly is reduced, and the external space is saved.

    本发明涉及一种带溃缩功能的转向管柱。包括管柱、铝铸管、手柄、手柄轴、支架,所述铝铸管和支架置于铝铸管外侧,手柄轴穿过支架和铝铸管夹紧管柱,手柄置于手柄轴一端,所述管柱外侧连接吸能装置,所述吸能装置下侧面带有第一啮合齿,铝铸管内横向装有第一销轴,销轴上固定装有齿石,齿石上设有第二啮合齿,第二啮合齿与第一啮合齿啮合,所述手柄轴上套有拨块,拨块带动齿石转动。本申请中的齿石、拨块等实现溃缩功能的大多数零件包裹在铝铸管内部,减少转向管柱总成裸露外部零件过多而造成零件性能的影响(例如:零件表面积灰,进入异物产生异响,卡滞等),并且节约了外部空间。
