The invention discloses an auxiliary frame reinforcing plate with welding connection structures, an installation method and an auxiliary frame. The auxiliary frame reinforcing plate comprises two auxiliary frame longitudinal beam upper plates and an auxiliary frame front cross beam upper plate, and the two auxiliary frame longitudinal beam upper plates are connected to the two ends of the auxiliary frame front cross beam upper plate through the welding connection structures respectively; an overlapping surface is arranged at the connecting position of the auxiliary frame longitudinal beam upper plate and the auxiliary frame front cross beam upper plate, and the connecting position is connected by welding; the auxiliary frame longitudinal beam upper plate and the auxiliary frame front cross beam upper plate are connected through the welding seam connecting structure, the local stress of the welding seam can be remarkably reduced through the design of the welding seam connecting structure, the reliability and the using mileage of the auxiliary frame are improved, and the modal performance and the rigidity performance are improved; compared with the improvement of the overall structure of the existing auxiliary frame, only the local structure of the auxiliary frame needs to be improved, a new mold does not need to be arranged again, the cost is low, and the structure is simple.

    本发明公开了一种具有焊接连接结构的副车架加强板、安装方法及副车架,所述副车架加强板包括:两个副车架纵梁上板和一个副车架前横梁上板,所述两个副车架纵梁上板分别通过焊接连接结构连接在副车架前横梁上板的两端;所述副车架纵梁上板和副车架前横梁上板的连接位置处有重合面,连接位置采用烧焊连接;本发明的副车架纵梁上板和副车架前横梁上板之间通过焊缝连接结构连接,通过对焊缝连接结构的设计可以显著降低焊缝局部应力,提供副车架的可靠性和使用里程,以及模态和刚度性能提升;与现有的对副车架的整体结构进行改进相比,本发明只需要对副车架的局部结构进行改进即可,也无需重新设置新的模具,成本低廉且结构简单。
