The invention provides an auxiliary frame and a vehicle, and belongs to the technical field of automobile accessories. The auxiliary frame comprises an upper plate assembly, a lower plate assembly and a reinforcing plate, the upper plate assembly is connected with the lower plate assembly, and a cavity is formed between the upper plate assembly and the lower plate assembly. The reinforcing plate comprises a top plate, a connecting plate and a bottom plate, the reinforcing plate is located in the cavity, the top plate is connected with the upper plate assembly, and the bottom plate is connected with the lower plate assembly. When the upper plate assembly is subjected to force applied by other parts, the upper plate assembly can sequentially transmit the force to the reinforcing plate and the lower plate assembly. Therefore, the overall stress of the auxiliary frame can be more uniform, so that the upper plate assembly and the lower plate assembly bear smaller force, the auxiliary frame is prevented from being deformed, and the rigidity of the auxiliary frame is improved. Therefore, the modality, rigidity, strength and other performance of the auxiliary frame can be improved and reinforced. In addition, under the requirement of the same performance, the thickness of the upper plate assembly or the lower plate assembly can be reduced, and therefore the weight of the auxiliary frame is reduced.

    本公开提供了一种副车架和车辆,属于汽车配件技术领域。副车架包括上板组件、下板组件和加强板,上板组件与下板组件连接,且上板组件和下板组件之间形成腔体。加强板包括顶板、连接板和底板,加强板位于腔体中,顶板与上板组件连接,底板与下板组件连接。当上板组件受到其他零部件施加的力时,上板组件能够将力依次传递至加强板和下板组件。这样,能够使得副车架整体受力更加均匀,从而使得上板组件和下板组件均承受较小的力,进而避免副车架产生形变,提高了副车架的刚度。因此,能够提高加强副车架的模态、刚度和强度等性能。此外,因此在同等性能的要求下,可以减小上板组件或下板组件的厚度,从而降低副车架的重量。
