The invention discloses a bearing sealing structure of a steering column and a dash panel. The bearing sealing structure comprises a rubber dust cover and a rolling bearing; the steering column comprises a steering intermediate shaft, and the rolling bearing is assembled on the steering intermediate shaft with a small gap; the rubber dust cover is also fixedly connected with the dash panel while being assembled on the rolling bearing; the bearing sealing structure further comprises a damping ring; the damping ring is fixedly assembled on an inner ring of the rolling bearing and used for filling the small gap between the rolling bearing and the steering intermediate shaft; and meanwhile the damping ring can provide friction force to enable the steering intermediate shaft to drive the inner ring of the rolling bearing to rotate together. And the rolling bearing is enabled to axially slide relative to the steering intermediate shaft. The damping ring is additionally arranged on the inner ring of the rolling bearing so as to eliminate the small gap between the rolling bearing and the steering intermediate shaft, the possibility that dust or muddy water enters the small gap is completely eradicated, and the sealing performance is greatly improved.
本发明公开了一种转向柱与前围板的轴承密封结构,包括橡胶防尘罩和滚动轴承;所述转向柱包括转向中间轴,所述滚动轴承以小间隙装配于转向中间轴上;所述橡胶防尘罩在装配于滚动轴承上的同时还与所述前围板固定连接;所述轴承密封结构还包括阻尼环,所述阻尼环固定装配于所述滚动轴承的内圈,用于填充滚动轴承与转向中间轴之间的小间隙,同时,所述阻尼环还能提供摩擦力使转向中间轴带动滚动轴承的内圈一起转动,还可使滚动轴承相对转向中间轴进行轴向滑动。本发明通过在滚动轴承的内圈加装阻尼环以消除滚动轴承与转向中间轴之间的小间隙,完全杜绝了灰尘或泥水进入其中的可能性,大大提高了密封性能。
