The invention provides a universal joint fork, a universal transmission device, a steering system and an automobile. The universal joint fork comprises a joint fork head part and a joint fork main body part, and the joint fork head part is U-shaped; the yoke body part extends in the first direction and is connected with the yoke head part, the yoke body part comprises a first through hole and a second through hole, the first through hole penetrates through the yoke body part in the first direction to be used for containing a transmission shaft, the second through hole penetrates through the yoke body part in the second direction, and the axis of the second through hole and the axis of the first through hole intersect and are perpendicular to each other; the first direction is perpendicular to the second direction, a stress part is formed on the yoke body part, at least part of the stress part extends in the first direction, and the stress part is configured to improve the acting force borne by the universal joint yoke. The universal joint fork has good structural strength, the probability that the universal joint fork is damaged by stress during power transmission can be reduced, and the reliability of the universal joint fork is improved.

    本申请提供一种万向节叉、万向传动装置、转向系统以及汽车。万向节叉包括节叉头部和节叉主体部,节叉头部形成为U形;节叉主体部沿第一方向延伸并与节叉头部连接,节叉主体部包括第一通孔和第二通孔,第一通孔沿第一方向贯穿节叉主体部,以用于容纳传动轴,第二通孔沿第二方向贯穿节叉主体部,第二通孔的轴线与第一通孔的轴线相交且垂直,第一方向与第二方向垂直,其中,在节叉主体部上形成有应力部,应力部的至少部分沿第一方向延伸,应力部被配置为改善万向节叉受到的作用力。本申请的万向节叉具有良好的结构强度,能够降低万向节叉在进行动力传递时受到应力损伤的概率,提高了万向节叉的可靠性。
