The invention relates to a high-strength automobile steering system intermediate shaft device which comprises an intermediate shaft piece, a universal joint fork and a cross shaft and further comprises a rolling body, the rolling body comprises a rotating seat and an upper adapter arm, a center hole is formed in the rotating seat, an upper half groove is formed in the upper adapter arm, and a lower half groove is formed in the lower half groove. The opposite sides of the two fork arms of the universal joint fork are provided with lower adapter arms in the circumferential direction of respective shaft holes, the lower adapter arms are provided with lower half grooves, the cross shaft comprises a center base and center shafts, the center base is in a cross shape, the center shafts are arranged at the ends of the center base, and the ends of the center base are provided with annular matching grooves surrounding the center shafts. The rolling body is sleeved on the central shaft through the central hole, the rotating seat of the rolling body is rotatably connected in the annular matching groove, and the upper adapter arm and the lower adapter arm are wound on the central shaft and are fixed with each other. According to the technical scheme, the matching surface area between the cross shaft pivot and the shaft hole of the universal joint fork is large, the structural strength is high, when an automobile runs, abrasion, fatigue, deformation and breakage are not prone to being caused between matching positions, and safety is high.

    本发明涉及一种高强度汽车转向系统中间轴装置,它包括中间轴件、万向节叉和十字轴,它还包括滚动体,滚动体包括转座和上转接臂,转座上开设有中心孔,上转接臂上开设有上半槽,万向节叉两叉臂相对侧于各自轴孔的周向形成有下转接臂,下转接臂上开设有下半槽,十字轴包括中心座和中心轴,中心座呈十字形,中心轴设于中心座的每一端上,中心座的每一端上开设有环绕中心轴的环配槽,滚动体通过中心孔套装于中心轴上,其转座转动连接于环配槽中,上转接臂和下转接臂包绕于中心轴上并相固定。本技术方案十字轴枢轴与万向节叉轴孔间的配合面面积大,结构强度高,汽车行驶时,配合位间不易引起磨损和疲劳以及产生变形和断裂,安全性较高。
