The invention discloses a high-strength truck wheel structure, and relates to the technical field of automobile wheel manufacturing, the high-strength truck wheel structure comprises a spoke and a rim which are pressed and welded, the rim comprises an axial outer rim and an axial inner rim, and the axial outer rim is connected with the axial inner rim through a rim base; the axial inner rim comprises a near-end rim, the tail end of the near-end rim is connected with a tire bead seat edge, and the far end of the tire bead seat edge inclines towards the rim base part and extends until the far end of the tire bead seat edge is directly connected with the rim base part; and a fixed connection part is arranged at an opening of the spoke and is welded and fixed with the inner side of the bead seat edge. According to the scheme, a groove top fillet, a rim straight edge and a transition circular arc in an early-stage design structure are omitted, and the bead seat edge is directly connected with the circular arc transition section in the rim base part; therefore, the groove top fillet stress concentration phenomenon is avoided.
本发明公开了一种高强度卡车车轮结构,涉及汽车的车轮制造技术领域,包括压装并焊接的轮辐和轮辋,所述轮辋包括轴向外轮辋和轴向内轮辋,所述轴向外轮辋与所述轴向内轮辋之间通过轮辋基部相连接;所述轴向内轮辋包括近端轮缘,所述近端轮缘的末端处连接有胎圈座边,所述胎圈座边的远端向着所述轮辋基部的方向倾斜并且延伸,直至与所述轮辋基部直接连接;所述轮辐的开口处具有固接部,所述固接部与所述胎圈座边的内侧焊接固定。本方案取消了前期设计结构中的槽顶圆角、轮辋直边和过渡圆弧,采用胎圈座边与轮辋基部中的圆弧过渡段直接连接;因此没有槽顶圆角应力集中现象。
