According to the adjustable energy-absorbing collapsing method for the automobile steering column, an upper column and a lower column which are connected in a sleeved mode are included, and the upper column is fixedly connected with a connecting frame and arranged on a fixing frame in a sliding mode in the collapsing direction through the connecting frame; the connecting frame is fixedly connected to the fixing frame through the crumple blocks. The energy absorption device is fixedly arranged on the fixing frame, and when crumple begins, the connecting frame drives the crumple block to generate relative displacement relative to the fixing frame, and then the energy absorption device is coupled with the connecting frame or the upper pipe column which displaces by a set distance; the energy absorption device generates damping force on the connecting frame or the upper pipe column in the displacement process until the displacement stroke of the upper pipe column is finished; the energy absorption device does not participate in the process of generating the crumple peak force, and the crumple block plays a main role, so that the transition fluctuation between the crumple peak force and the crumple lasting force is reduced, meanwhile, the crumple curve is convenient to adjust, the stable crumple process can play an effective role in reducing the speed of a driver, and the driver is safely and effectively protected.
一种汽车转向管柱的可调吸能溃缩方法,包括相互套接的上管柱和下管柱,上管柱与连接架固定连接并通过该连接架沿溃缩方向滑动设置在固定架上;通过溃缩块将连接架固定连接在固定架上;在固定架上固定设置吸能装置,当溃缩开始,连接架带动溃缩块相对固定架产生相对位移后,使吸能装置与位移设定距离的连接架或上管柱产生耦合;使吸能装置对位移过程中的连接架或上管柱产生阻尼力,直至上管柱的位移行程结束;使吸能装置不参于产生溃缩峰值力的过程,并由溃缩块起主要作用,从而减小溃缩峰值力和溃缩持续力之间过渡的波动,同时便于调整溃缩曲线,使稳定的溃缩过程能够对驾驶员起到有效的降速作用,并对驾驶员起到安全有效的保护作用。
