The invention belongs to the technical field of automobile technical accessories, and particularly relates to a rolling ball type steering transmission shaft structure of a passenger car. The abrasion resistance of the transmission shaft assembly is improved, the service life is prolonged, and spline abrasion between a sliding sleeve and a transmission shaft is reduced. A transmission shaft is included. A sliding sleeve is sleeved outside the transmission shaft, a steel ball retainer is arranged on the transmission shaft, a plurality of steel ball mounting holes are distributed on the circumference of the steel ball retainer, steel balls are mounted in the steel ball mounting holes, and the radial clearance of the transmission shaft assembly is eliminated by selecting the diameters of the steel balls. After the transmission shaft and the shaft end joint fork are welded together, the sealing cover, the rubber dustproof ring, the gasket and the steel ball retainer assembly are sequentially installed and limited through the shaft check ring, and the steel ball retainer assembly rolls and slides in a ball groove of the transmission shaft. The transmission shaft and the sliding sleeve slide relatively to transmit torque through reciprocating rolling of the steel balls of the rolling ball retainer assembly in the ball channels.

    本发明属于汽车技术配件技术领域,尤其涉及一种乘用车滚珠式转向传动轴结构。其为解决传动轴总成的耐磨性提升使用寿命,降低了滑动套和传动轴之间花键磨损。包括传动轴;所述传动轴外套设有滑动套,传动轴上设置有钢球保持架,钢球保持架的圆周上分布有多个钢球安装孔,钢球安装孔内安装有钢球,通过选配钢球直径来消除传动轴总成的径向间隙。传动轴与轴端节叉焊接相连后,传动轴与轴端节叉焊接在一起后,依次安装密封盖、橡胶防尘圈、垫片和钢球保持架组件用轴用挡圈限位,使钢球保持架组件在传动轴球道内滚动滑移。传动轴与滑动套之间通过滚球保持架组件的钢球在球道内往复滚动实现相对滑动来传递扭矩。
