The automobile electric steering column comprises a shell combination and an input and output shaft combination, the input and output shaft combination penetrates through the shell combination, the shell combination comprises a body and a first bearing, a first mounting hole used for mounting the input and output shaft combination is formed in the middle of the body, and a second mounting hole used for mounting the input and output shaft combination is formed in the middle of the body. The inner wall of the installation hole protrudes inwards to form a rib plate, the outer wall of the input and output shaft combination protrudes outwards to form a limiting block, a first containing cavity used for installing the first bearing is formed between the limiting block and the rib plate, the outer ring of the first bearing is connected with the body, and the inner ring of the first bearing is connected with the input and output shaft combination. The two ends of the first bearing are limited through the limiting block and the rib plate respectively, so that the first bearing can be directly installed on the body and the input and output shaft combination, a partition plate and an O-shaped ring are not needed, the problem that performance is affected due to insufficient rigidity is effectively solved, the structure is simple, and the stability of products is effectively guaranteed.

    本发明提供了一种带有新结构壳体的汽车电动转向管柱,包括壳体组合和输入输出轴组合,输入输出轴组合贯穿壳体组合,壳体组合包括本体和第一轴承,本体的中部开有用于安装输入输出轴组合的第一安装孔,安装孔的内壁向内凸出形成一筋板,输入输出轴组合的外壁向外凸出形成一限位块,限位块与筋板之间形成用于安装第一轴承的第一容纳腔,第一轴承的外圈与本体连接,第一轴承的内圈与输入输出轴组合连接。通过限位块和筋板分别对第一轴承的两端进行限位,使第一轴承能够直接安装在本体和输入输出轴组合上,不需要借助隔板和O形圈,有效解决了因刚性不足而影响性能,结构简单,有效的保证了产品的稳定性。
