The invention discloses an auxiliary frame of a vehicle, a vehicle body assembly of the vehicle and the vehicle. The auxiliary frame comprises a first cross beam and a second cross beam, two auxiliary frame longitudinal beams; the third cross beam is located between the first cross beam and the second cross beam, and the third cross beam is connected between the two auxiliary frame longitudinal beams; wherein each auxiliary frame longitudinal beam comprises a first longitudinal beam section and a second longitudinal beam section which are connected, an included angle is formed between the first longitudinal beam section and the second longitudinal beam section, the first cross beam is clamped between the first longitudinal beam sections of the two auxiliary frame longitudinal beams, and the first longitudinal beam sections are obliquely arranged towards the outer side of the auxiliary frame in the direction from the second cross beam to the first cross beam; the second cross beam is connected between the second longitudinal beam sections of the two auxiliary frame longitudinal beams. The front end structure of the auxiliary frame longitudinal beam is expanded and extends forwards, front-back swing of the first cross beam can be restrained, the structural stability of the auxiliary frame is improved, a vehicle body installation tower connected with the auxiliary frame longitudinal beam can be designed to be smaller under the target of the same rigidity, and then design materials are saved.

    本发明公开了一种车辆的副车架、车辆的车身组件以及车辆,副车架包括:第一横梁和第二横梁;两个副车架纵梁;第三横梁,第三横梁位于第一横梁和第二横梁之间,第三横梁连接在两个副车架纵梁之间;其中,每个副车架纵梁均包括相连的第一纵梁段和第二纵梁段,第一纵梁段和第二纵梁段间形成夹角,第一横梁夹设在两个副车架纵梁的第一纵梁段之间,且从第二横梁至第一横梁方向,第一纵梁段朝副车架外侧倾斜设置,第二横梁连接在两个副车架纵梁的第二纵梁段之间。通过扩大副车架纵梁前端结构并向前延伸,可以抑制第一横梁前后摆动,提高副车架的结构稳定性,在同等刚度目标下,与副车架纵梁连接的车身安装塔可以设计更小,进而节约设计材料。
