The invention relates to a preparation process of a vehicle frame cross member, the vehicle frame cross member, a vehicle frame assembly and a vehicle, and the preparation process of the vehicle frame cross member comprises the following steps: rolling a plate to enable the plate to have a bending radian; the two ends, in the bending direction, of the plate are connected to form the frame cross member; high-pressure gas is inflated into the frame cross beam, so that a connecting part, a mounting part and an avoiding part are sequentially formed on the frame cross beam in the lengthwise direction of the frame cross beam; wherein the cross sections of the frame cross member at the connecting part, the mounting part and the avoiding part are different in shape. The connecting part, the mounting part and the avoiding part with different shapes of cross sections are respectively formed on the frame cross beam to form the variable-cross-section frame cross beam, so that the cross section shapes of different positions on the frame cross beam are mutually matched with corresponding mounting environments, the total mounting space of the frame cross beam can be reduced, and the mounting efficiency of the frame cross beam is improved. And the mounting adaptability of the frame cross member and other structures in the vehicle is improved, so that the whole structure of the vehicle is more compact.

    本发明涉及一种车架横梁的制备工艺、车架横梁、车架总成以及车辆,其中,车架横梁的制备工艺包括步骤:对板料进行辊压,使板料具有弯曲弧度;将板料沿其弯曲方向的两端连接,以形成车架横梁;向车架横梁的内部充入高压气体,以在车架横梁沿其纵长方向上依次形成连接部、安装部以及避让部;其中,车架横梁在连接部、安装部及避让部处的横截面的形状不同。本申请在车架横梁上分别形成具有不同形状横截面的连接部、安装部以及避让部,以形成变截面的车架横梁,使得车架横梁上不同位置的截面形状与对应的安装环境相互匹配,能够减小车架横梁的总安装空间,提高车架横梁与车辆中其他结构的安装适配度,使得车辆整体结构更加紧凑。
