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 auxiliary frame longitudinal beams located on the outermost side are connected with control arm mounting frames. The third cross beam is connected with the multiple auxiliary frame longitudinal beams, and the two ends of the third cross beam correspond to control arm mounting frames of the corresponding auxiliary frame longitudinal beams respectively; the suspension mounting frame is fixedly arranged on the third cross beam; the supporting frame is located between the third beam and the second beam. Therefore, the third cross beam can support the control arm mounting frame, the rigidity of the control arm mounting frame is improved, the transmission of road noise to a passenger compartment through the control arm 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. Vibration and noise transmitted from the power assembly to the passenger compartment can be effectively restrained, and therefore the riding comfort of passengers is improved.

    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,位于最外侧的副车架纵梁均连接有控制臂安装架;第三横梁和多个副车架纵梁均连接,第三横梁的两端分别与相应副车架纵梁的控制臂安装架对应设置;悬置安装架固设于第三横梁;支撑架位于第三横梁和第二横梁之间。由此,第三横梁可以对控制臂安装架起到支撑作用,提升控制臂安装架的刚度,减小路面噪音通过控制臂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,可以有效抑制动力总成向乘员舱传递振动和噪音,从而提升乘客的乘坐舒适度。
