The invention provides a full-hollow rubber ball pin and a preparation method thereof. The ball pin comprises a hollow pin shaft, a thin-wall steel jacket and a rubber lining layer, wherein the two ends of the hollow pin shaft are flat, the hollow pin shaft is integrally formed by flattening the two ends of a seamless steel pipe, the thin film steel outer sleeve is arranged in the middle outside the hollow pin shaft in a sleeving mode, and the portion between the thin film steel outer sleeve and the hollow pin shaft is filled with the rubber lining in an integrated glue injection vulcanization mode. A solid forging structure pin shaft of an original thrust rod rubber core is changed, the material utilization rate is increased, and the cost and the weight are reduced.

    本发明提供一种全空心橡胶球销及其制备方法,球销包括空心销轴、薄壁钢外套以及橡胶衬层;其中,所述空心销轴两端呈扁平状,空心销轴由无缝钢管两端压扁一体制成,所述薄膜钢外套套设于所述空心销轴外中间位置,所述橡胶衬层通过一体注胶硫化的方式填充于薄壁钢外套与空心销轴之间。本发明改变了原推力杆胶芯的实心锻造结构销轴,提高了材料利用率,降低了成本和重量。
