The invention relates to a three-bearing system for a steering column. The three-bearing system comprises a first bearing, a second bearing, a first clamping ring, a second clamping ring and a third bearing, wherein the first bearing and the second bearing are angular contact bearings and are respectively pressed in an inner tubular column of the steering tubular column, and a steering tube of the steering tubular column penetrates through the first bearing and the second bearing and is in clearance fit with the first bearing and the second bearing; the first clamping ring and the second clamping ring are clamping rings with inverted teeth, and the first clamping ring and the second clamping ring are pressed on the steering tube and used for fixing the first bearing and the second bearing; the third bearing is a semi-rigid bearing and has large flexibility, an outer ring of the third bearing is pressed in an aluminum cast pipe of the steering column, and an inner ring of the third bearing is in interference fit with a steering shaft of the steering column and used for positioning the steering shaft and achieving radial compensation at the same time. The system is simple in structure and convenient to use, and radial and axial gaps of the steering column are greatly reduced.

    本发明涉及一种用于转向管柱的三轴承系统,包括第一轴承、第二轴承、第一卡环、第二卡环、第三轴承;其中,第一轴承和第二轴承为角接触轴承,分别压装在转向管柱的内管柱内,转向管柱的转向管穿过第一轴承、第二轴承,与第一轴承、第二轴承间隙配合;第一卡环和第二卡环为带倒齿的卡环,第一卡环、第二卡环均压装在转向管上,用于将第一轴承、第二轴承固定;第三轴承为半刚性轴承,具有较大的柔性,第三轴承的外圈压装在转向管柱的铝铸管内,第三轴承的内圈与转向管柱的转向轴过盈配合,用于对转向轴进行定位,同时实现径向补偿。该系统结构简单,使用方便,且极大的减小了转向管柱的径向和轴向间隙。
