The novel steering column comprises a steering column sleeve and an inner shaft, and the steering column sleeve is composed of a steering column lower sleeve and a steering column upper sleeve which are coaxially arranged; the inner shaft comprises a steering column lower connecting shaft, a telescopic structure outer sleeve, a telescopic structure inner shaft and a steering column upper connecting shaft which are coaxially arranged in sequence, and a ball guide mechanism is arranged between the telescopic structure inner shaft and the telescopic structure outer sleeve; the steering column lower sleeve, the steering column lower connecting shaft and the telescopic structure outer sleeve form a fixed section; and the steering column upper sleeve, the telescopic structure inner shaft and the steering column upper connecting shaft form a movable section. According to the novel steering column, transmission is guaranteed, meanwhile, the movable section can axially move relative to the fixed section, the ball guide mechanism is additionally arranged, and compared with a common spline structure, the friction torque of the structure in the axial direction is small, and adjustment is more convenient.

    本发明公开了一种新型转向管柱,包括转向管柱套管和内轴,转向管柱套管由同轴设置的转向管柱下套管和转向管柱上套管组成;内轴包括同轴依次设置的转向管柱下连接轴、伸缩结构外套筒、伸缩结构内轴和转向管柱上连接轴,伸缩结构内轴与伸缩结构外套筒之间设有滚珠引导机构;转向管柱下套管、转向管柱下连接轴和伸缩结构外套筒形成固定段;转向管柱上套管、伸缩结构内轴和转向管柱上连接轴形成活动段。本发明的新型转向管柱在保证传动的同时,活动段可相对于固定段轴向移动,并增加了滚珠引导机构,相比一般的花键结构,该种结构在轴向方向摩擦力矩较小,调节更为方便。
