The invention relates to a long-stroke telescopic adjusting steering column which comprises an inner pipe column, a supporting sleeve and a length adjusting mechanism, and is characterized in that a guide pipe is arranged between the inner pipe column and the supporting sleeve, the inner pipe column is sleeved with a guide pipe, and the guide pipe is sleeved with the supporting sleeve; the length adjusting mechanism is installed on the guide pipe, and two adjusting nuts capable of moving in opposite directions or moving in opposite directions on the length adjusting mechanism are fixedly connected with the inner pipe column and the supporting sleeve respectively; a guide mechanism is further arranged among the inner pipe column, the guide pipe and the supporting sleeve. According to the steering column, the guide pipe is additionally arranged between the inner pipe column and the supporting sleeve, the inner pipe column is arranged in the guide pipe in a sleeved mode, the guide pipe is arranged in the supporting sleeve in a sleeved mode, two-stage stretching and retracting are achieved by installing the guide pipe, then stretching and retracting of the guide pipe and the inner pipe column are adjusted through the length adjusting mechanism on the guide pipe, and a larger length adjusting range is achieved.

    本发明涉及一种长行程伸缩式调节转向柱,包括内管柱、支撑套筒、长度调节机构,所做的改进是,所述内管柱与支撑套筒之间设置有导向管,所述内管柱套设在导向管内,所述导向管套设在支撑套筒内;所述长度调节机构安装在所述导向管上,长度调节机构上的两个能够向相对方向运动或向相反方向运动的调节丝母分别与内管柱、支撑套筒固连;所述内管柱、导向管与支撑套筒之间还设置有导向机构。该转向柱在内管柱与支撑套筒之间增设导向管,内管柱套设在导向管内,导向管套设在支撑套筒内,通过安装导向管实现二级伸缩,之后通过导向管上的长度调节机构调节导向管和内管柱的伸缩,实现更大的长度调节范围。
