The invention discloses a frame cross member and a vehicle, the frame cross member comprises a beam body, the beam body is constructed as a variable cross-section pipe, the middle part of the beam body is provided with a circular cross section, and the end part of the beam body is provided with a rectangular cross section; the upper mounting bracket is connected with the upper surface of the end part of the beam body, the lower mounting bracket is connected with the lower surface of the end part of the beam body, and the upper mounting bracket and the lower mounting bracket are oppositely arranged in the vertical direction and are both used for being connected with a frame longitudinal beam. According to the vehicle frame cross beam, the beam body is constructed in the mode that the shapes of the cross sections from the middle to the two ends are evenly changed, the equal-strength design is adopted, the material cost is saved, and the overall weight of the vehicle frame cross beam is reduced. Meanwhile, the beam body can be provided with a large connecting supporting face so that the beam body can be connected with an upper installation support and a lower installation support, and it is guaranteed that all parts of the frame cross beam have good connecting stability.

    本申请公开了一种车架横梁和车辆,所述车架横梁包括:梁本体,所述梁本体构造为变截面管,所述梁本体的中部具有圆形横截面且所述梁本体的端部具有矩形横截面;上安装支架和下安装支架,所述上安装支架与所述梁本体的端部的上表面相连,所述下安装支架与所述梁本体的端部的下表面相连,所述上安装支架与所述下安装支架沿上下方向正对设置且均用于与车架纵梁相连。本申请的车架横梁,将梁本体构造为从中部到两端的横截面的形状均匀变化,采用等强度设计,节省材料成本,且利于减轻车架横梁的整体重量。同时,可使得梁本体能够提高较大的连接支撑面以用于分别与上安装支架、下安装支架相连,保证车架横梁的各个部件之间具有很好的连接稳定性。
