The invention relates to the technical field of vehicles, and discloses a frame longitudinal beam, a frame assembly and a vehicle, the frame longitudinal beam comprises a longitudinal beam main body, the longitudinal beam main body is an aluminum alloy structural member, and the longitudinal beam main body comprises a beam web and two beam wing plates; wherein one beam wing plate is connected to one end of the beam web in the width direction and located on one side of the beam web in the thickness direction, the other beam wing plate is connected to the other end of the beam web in the width direction and located on one side of the beam web in the thickness direction, and the thickness of the beam wing plate is not equal to that of the beam web. The longitudinal beam main body adopts the aluminum alloy structural member, and the thickness of the beam wing plate is unequal to that of the beam web plate, so that the weight of the frame longitudinal beam can be greatly reduced on the premise of not sacrificing the structural strength, and the frame longitudinal beam has higher bending resistance and roll resistance; in addition, the coating process can be omitted, the coating cost is saved, and the electrochemical corrosion problem can be avoided.

    本发明涉及车辆技术领域,公开了一种车架纵梁、车架总成及车辆,其中的车架纵梁包括纵梁主体,纵梁主体为铝合金结构件,纵梁主体包括梁腹板和两个梁翼板,其中一个梁翼板连接于梁腹板宽度方向一端且该梁翼板位于梁腹板厚度方向一侧,另一个梁翼板连接于梁腹板宽度方向的另一端且该梁翼板位于梁腹板厚度方向一侧,梁翼板的厚度与梁腹板的厚度不等。纵梁主体采用铝合金结构件,并且将梁翼板的厚度与梁腹板的厚度不等,能够在不牺牲结构强度的前提下,实现对车架纵梁的大幅度降重,且具有较高的抗弯能力和抗侧倾能力;此外,还能够省去涂装工艺,节约涂装费用,能够避免发生电化学腐蚀问题。
