The embodiment of the invention provides an aluminum alloy frame assembly and a vehicle, and relates to the technical field of frames. The aluminum alloy frame assembly comprises two longitudinal beams and a plurality of cross beams; the longitudinal beam comprises a longitudinal beam main body and a wrapping part which are fixedly connected; the plurality of cross beams are arranged between the two longitudinal beams; connecting plates are connected between the transverse beams and the longitudinal beams, first fixing pieces are arranged between the connecting plates and the longitudinal beams, the connecting plates are partially wrapped between the longitudinal beam bodies and the back wrapping parts, and the first fixing pieces are constructed to fix the connecting plates to the longitudinal beams. According to the aluminum alloy frame assembly, the longitudinal beam is provided with the back wrapping part, so that the bending resistance and the torsion resistance of the longitudinal beam can be improved, the bending resistance and the torsion resistance of the aluminum alloy frame assembly can be improved, the service life of the aluminum alloy frame assembly can be prolonged, and normal use of a vehicle is guaranteed.

    本发明实施例提供一种铝合金车架总成及车辆,涉及车架技术领域。铝合金车架总成包括两个纵梁和多个横梁;纵梁包括固定连接的纵梁主体和回包部;多个横梁设置在两个纵梁之间;各个横梁与纵梁之间连接有连接板,连接板与纵梁之间设置有第一固定件,连接板部分包裹在纵梁主体和回包部之间,第一固定件被构造为将连接板固定在纵梁上。通过纵梁设置回包部,可以提高纵梁的抗弯曲性能和抗扭转性,从而可以提高铝合金车架总成的抗弯曲性能和抗扭转性,进而可以提高铝合金车架总成的寿命减短,保证车辆的正常使用。
