The invention discloses a rear axle assembly and a vehicle, and the rear axle assembly comprises a circular rectangular cross beam which is of a hollow structure, and the two ends of the circular rectangular cross beam are provided with welding matching holes; the first end part area and the second end part area of the circular rectangular cross beam are gradually sunken towards the middle area of the circular rectangular cross beam, so that the first inner circumferential surface and the second inner circumferential surface of the circular rectangular cross beam are attached to form a V-shaped section structure; the first inner circumferential surface is provided with a convex part which protrudes outwards, the second inner circumferential surface is provided with a concave part which is concave inwards, and the convex part extends into the concave part and is completely attached to the concave part; the rear axle assembly further comprises two assembling parts, and the assembling parts are arranged on the welding matching holes. According to the rear axle assembly provided by the embodiment of the invention, the convex part can be completely embedded into the concave part, so that the convex part is completely attached to the concave part, and the first inner circumferential surface is further attached to the second inner circumferential surface.

    本发明公开了一种后轴总成和车辆,后轴总成包括:圆矩形横梁,所述圆矩形横梁为中空结构,其两端具有焊接匹配孔;所述圆矩形横梁的第一端部区、第二端部区逐渐向所述圆矩形横梁的中部区凹陷,以致所述圆矩形横梁第一内周面和第二内周面贴合形成V形截面结构;所述第一内周面上具有向外凸起的凸起部,所述第二内周面上具有向内凹陷的凹陷部,所述凸起部伸入所述凹陷部且与所述凹陷部完全贴合;后轴总成还包括:两个组装件,所述组装件设于所述焊接匹配孔上。根据本发明实施例的后轴总成,该方案能使凸起部完全嵌入凹陷部内,从而实现凸起部和凹陷部的完全贴合,进一步实现第一内周面和第二内周面贴合。
