The invention discloses a driving axle which is provided with a middle part, a connecting part and a hub mounting part in the axial direction X, and the connecting part and the hub mounting part are formed by extending from the middle part to the two ends. In the XZ plane, the side, close to the hub axis of the driving axle, of the connecting part is provided with a first arc section and a linear section which are connected in sequence, the first arc section is connected to the middle part and provided with a bending turning point A, and the linear section is connected to the hub mounting part; the side, away from the hub axis, of the connecting part is provided with a second arc section, and the two ends of the second arc section are connected with the middle part and the hub mounting part. The connecting part is provided with a cross section B in the axial direction X, the cross section B comprises a third line segment away from the axis of the hub and a fourth line segment close to the axis of the hub, the bending degree of the third line segment is larger than that of the fourth line segment, and in the axial direction X, the cross section B is gradually enlarged from the bending turning point A to the connecting positions of the two ends of the second arc line segment. Through the design, the bearing capacity is improved.

    本申请公开了一种驱动车桥,在轴向方向X上,驱动车桥具有中间部和从中间部开始向两端延伸形成的连接部和轮毂安装部。在XZ平面内,连接部靠近驱动车桥的轮毂轴线的一侧具有依次衔接的第一弧线段和直线段,第一弧线段衔接于中间部,第一弧线段具有弯曲转折点A,直线段衔接于轮毂安装部;连接部远离轮毂轴线的一侧具有第二弧线段,第二弧线段两端衔接中间部和轮毂安装部。连接部具有在轴向方向X的横截面B,横截面B包括远离轮毂轴线的第三线段和靠近轮毂轴线的第四线段,第三线段的弯曲度大于第四线段的弯曲度,且在轴向方向X上,以弯曲转折点A为起始点至第二弧线段两端的衔接位置,横截面B逐渐变大。上述设计使承载能力提升。
