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, the multiple auxiliary frame longitudinal beams are connected with the first cross beam and the second cross beam, and the outer side of the auxiliary frame longitudinal beam located on the outermost side is connected with a control arm rear installation frame, a supporting frame and a stabilizer bar installation support. The third beam is located between the first beam and the second beam. The support frame is connected between the third cross beam and the second cross beam; and the stabilizer bar mounting bracket is connected with the corresponding control arm rear mounting frame and the corresponding support frame. Therefore, the auxiliary frame longitudinal beam supports the control arm rear mounting frame to improve the rigidity of the control arm rear mounting frame, noise transmitted to a passenger compartment through the control arm rear mounting frame is reduced, the supporting frame supports the third cross beam to improve the longitudinal rigidity of the third cross beam, and then the rigidity and strength of the auxiliary frame are improved. The vibration and noise transmitted to the passenger compartment by the power assembly are effectively inhibited, and the risk of stress concentration on the stabilizer bar mounting bracket can be reduced.

    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;多个副车架纵梁均与第一横梁、第二横梁连接,位于最外侧副车架纵梁的外侧连接有控制臂后安装架、支撑架和稳定杆安装支架;第三横梁位于第一横梁和第二横梁之间;支撑架连接在第三横梁和第二横梁之间;稳定杆安装支架与相应控制臂后安装架和相应支撑架均连接。由此,副车架纵梁支撑控制臂后安装架以提升控制臂后安装架的刚度,减小噪音通过控制臂后安装架向乘员舱传递,支撑架支撑第三横梁以提升第三横梁的纵向刚度,进而提升副车架的刚度和强度,有效抑制动力总成向乘员舱传递振动和噪音,还能降低稳定杆安装支架上发生应力集中的风险。
