The invention discloses an automobile electric power steering column, and relates to the technical field of automobile steering systems. The steering column comprises a lower sleeve, an upper sleeve,a plastic fixing block, an upper installation support, a safety block, a steel belt, a locking nut, a thrust bearing, a handle, a fastener, a handle bolt, a left support plate with an arc-shaped through hole, and a right support plate with an arc-shaped through hole, the steering column further comprises a sliding cam, a fixed cam, a tooth pad, a wave spring and a toothed cam. The tooth pad is provided with an arc-shaped through hole; the sliding cam, the fixed cam and the toothed cam are respectively provided with the circular through hole, and one surface of the toothed cam is provided withteeth meshed with the tooth pad and two convex parts; the handle bolt sequentially penetrates through the toothed cam, the wave spring, the tooth pad, the right support plate, the fastener, the left support plate, the fixed cam, the sliding cam and the thrust bearing from right to left and is finally screwed on the handle bolt through the locking nut. According to the automobile electric power steering column, under the action of the wave spring, the tooth pad and the toothed cam generate interaction force, and the vertical retention force of a steering wheel is increased.

    一种汽车电动助力转向管柱,涉及汽车转向系统技术领域。包括下套筒、上套筒、塑料固定块、上安装支架、保险块、钢带、锁紧螺母、推力轴承、手柄、紧固件、手柄螺栓、带有弧形通孔的左支架板和右支架板,转向管柱还包括滑动凸轮、固定凸轮、齿垫、波形弹簧、带齿凸轮,齿垫设有弧形通孔,滑动凸轮、固定凸轮、带齿凸轮均设有圆形通孔,带齿凸轮的一面设有与齿垫相啮合的齿和两个凸起部;手柄螺栓从从右往左依次穿过带齿凸轮、波形弹簧、齿垫、右支架板、紧固件、左支架板、固定凸轮、滑动凸轮、推力轴承,最后用锁紧螺母拧紧在手柄螺栓上。汽车电动助力转向管柱在波形弹簧的作用下齿垫和带齿凸轮产生相互作用力,增加方向盘的垂向保持力。
