The invention discloses an automobile steering column buffer system and an automobile thereof. The buffer system comprises a steering column and a steering column pipe. Two ends of the steering columnare in transmission connection with a steering wheel and a rotator, a middle section of the steering column is rotatably arranged in the steering column pipe through an installation bearing, an elastic limiting mechanism used for axially limiting the installation bearing is arranged on the inner wall of the middle of the steering column pipe, and a damping buffer mechanism used for achieving damping buffer on the installation bearing sliding downwards in an axial direction is arranged on a lower section of the steering column. Limiting and buffer are relatively independent, buffer efficiencyis effectively improved, safety performance for resisting accidents is greatly increased, safety of a driver is guaranteed, and repeated use can be achieved; and the damping buffer mechanism is provided with a magnetorheological fluid buffer mechanism, and a controller makes the magnetorheological fluid buffer mechanism perform adaptive buffer through a real-time impulse so that the buffer efficiency is greatly improved, and the driving safety is further increased.

    本发明公开了一种汽车转向柱缓冲系统及其汽车,其中缓冲系统包括转向柱和转向柱管,所述转向柱的两端分别与方向盘和转动器传动连接,所述转向柱中段通过安装轴承转动内套于转向柱管内,所述转向柱管中间内壁设置有用于对所述安装轴承轴向限位的弹性限位机构,所述转向柱的下段还设置有用于对轴向下滑的安装轴承起阻尼缓冲的阻尼缓冲机构;限位和缓冲相对独立,有效提高缓冲效率,大大提高抵御事故的安全性能,保障驾驶员的安全,并且可重复使用;通过将阻尼缓冲机构设置磁流变液缓冲机构,且控制器通过实时冲量控制磁流变液缓冲机构进行适应性缓冲,大大提高缓冲的效率,进一步提高驾驶的安全性。
