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 which are arranged at intervals in the first direction of the auxiliary frame, and the first cross beam is located on the front side of the second cross beam; the auxiliary frame longitudinal beams are connected with the first cross beam and the second cross beam, at least one auxiliary frame longitudinal beam penetrates through the first cross beam, the connecting base is fixedly connected with the first cross beam and the corresponding auxiliary frame longitudinal beam, the connecting base is further suitable for being fixedly connected with a vehicle body longitudinal beam of a vehicle, and the connecting base is used for installing a suspension. Therefore, the auxiliary frame longitudinal beam is arranged on the first cross beam in a penetrating mode, the connecting base is fixedly connected with the first cross beam, the corresponding auxiliary frame longitudinal beam and the vehicle body longitudinal beam of the vehicle, a rigid fixed connection structure can be formed, and therefore the rigidity of the auxiliary frame is improved, and a power assembly of the vehicle is installed on the connecting base in a suspended mode. 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沿副车架的第一方向间隔排布,且第一横梁位于第二横梁前侧;多个副车架纵梁均与第一横梁、第二横梁连接,且至少一个副车架纵梁穿设于第一横梁,连接座与第一横梁、相应副车架纵梁均固定连接,且连接座还适于与车辆的车身纵梁固定连接,连接座用于安装悬置。由此,通过副车架纵梁穿设于第一横梁,并且连接座与第一横梁、相应副车架纵梁、车辆的车身纵梁均固定连接,能够形成刚性固连结构,从而提升副车架的刚度,并且车辆的动力总成通过悬置安装于连接座后,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。
