The invention relates to the technical field of vehicles, and discloses a steering tubular column, a steering system and a vehicle, the steering tubular column comprises a tubular column body, an adjusting assembly and a driving assembly, the adjusting assembly comprises a first mounting seat and a second mounting seat, a collapsing assembly comprises a support, an energy absorption belt and a limiting piece, and the tubular column body can collapse in the axial direction; and after the second mounting base is broken, the second mounting base can move in the crumple direction to drive the energy absorption belt to deform in the axial direction to absorb energy. The limiting piece enables the first frame body of the support to abut against the first installation base, stable connection of the support and the first installation base can be guaranteed, displacement or torsion of the support is avoided, and therefore stable connection and work of the energy absorption belt are guaranteed, the energy absorption belt can provide stable absorption crumple force, impact is relieved, and the service life of the energy absorption belt is prolonged. The energy absorption belt is stably connected between the second mounting base and the support, slippage of the tubular column body and the second mounting base can be relieved, a driver is prevented from being impacted, and safety can be improved.

    本申请涉及车辆技术领域,公开了一种转向管柱、转向系统及车辆,包括管柱主体、调节组件和驱动组件,调节组件包括第一安装座和第二安装座,溃缩组件包括支架、吸能带和限位件,管柱主体能够沿轴向溃缩,使第二安装座受沿溃缩方向的冲击力使剪切件被剪断吸能,断开后,第二安装座能沿溃缩方向移动够带动吸能带沿轴向变形吸能。限位件将支架的第一架体抵接在第一安装座上,可保证支架与第一安装座稳定连接,避免支架移位或扭转,从而保证吸能带稳定连接和工作,以使吸能带能够提供稳定的吸收溃缩力,减缓了冲击,并且,吸能带在第二安装座和支架之间稳定连接,可减缓管柱主体以及第二安装座的滑移,避免冲击驾驶员,可提升安全性。
