The novel steering column assembly comprises a steering column upper section, an inner sleeve and an outer sleeve are sequentially arranged in the middle of the steering column upper section from inside to outside, the outer sleeve is provided with a strip-shaped groove and a protruding part, a fixing support is arranged on the outer side of the outer sleeve, and the protruding part is arranged on the outer side of the fixing support. The fixing support is fixedly connected to a steering column mounting support, and the steering column mounting support is mounted on a vehicle body support. A toothed plate limiting structure is arranged on one side of the fixing support and comprises a first toothed plate and a second toothed plate, the first toothed plate and the second toothed plate are both provided with gear teeth, the first toothed plate is arranged on the rotating shaft in a sleeving mode, the second toothed plate is installed on the fixing support, and the gear teeth are arranged on the first toothed plate and the second toothed plate. The gear teeth on the first toothed plate and the gear teeth on the second toothed plate are meshed with each other. The toothed plate structure is additionally arranged in the dip angle direction of the steering column for limiting, the toothed plate structure can be used for limiting in the radial direction, and non-collapse caused by energy attenuation of collision of the column is effectively prevented.
本发明提供一种新型带溃缩结构的转向管柱总成及车辆,包括转向管柱上段,转向管柱上段的中部从内到外依次设置有内套管和外套管,所述外套管上开设有条形槽和设置有凸出部,外套管外侧设置有固定支架,所述固定支架固定连接在转向管柱安装支架上,所述转向管柱安装支架安装在车身支架上;固定支架的一侧设置有齿板限位结构,所述齿板限位结构包括第一齿板和第二齿板,所述第一齿板和第二齿板上均设置有轮齿,所述第一齿板套设在所述转轴上,所述第二齿板安装在所述固定支架上,所述第一齿板和第二齿板上的轮齿相互咬合在一起。本发明在转向管柱倾角方向上增加齿板结构限位,该齿板结构可径向限位,有效防止管柱碰撞能量衰减导致未溃缩。
