The invention relates to an engine bearing beam, and discloses a connecting structure for an engine bearing beam. The structure comprises a first connection portion, the first connection portion is provided with a second connection portion fixedly connected with a doorsill edge beam, a third connecting part fixedly connected with an automobile body column A is connected beside the first connectionportion, arc-shaped reinforcing grooves are formed in the third connection portion and between the third connection portion and the second connection portion, arc-shaped covering shells are connectedto the reinforcing grooves, the side edges of the covering shells are connected with the peripheries of the reinforcing grooves, and the covering shells are fixed to the first connection portion; auxiliary holes are formed in the part between the first connection portion and the third connection portion and the covering shells; impact force is directly transmitted to a vehicle body framework without assembling parts, the transmission efficiency of the impact force is improved, the reinforcing grooves and the covering shells form a bulge, the bulge enables the first connection portion, the second connection portion and the third connection portion to form a whole, a force transmission channel is formed among the first connection portion, the second connection portion and the third connection portion, and the performance of bearing and transmitting the impact force is enhanced.

    本发明涉及发动机承重梁,公开了一种发动机承重梁用连接结构,包括第一连接部,第一连接部设有与门槛边梁固定连接的第二连接部,第一连接部旁连有与车身A柱固定连接的第三连接部,第三连接部上以及第三连接部与第二连接部之间设有圆弧形的加强槽,加强槽连有圆弧形的覆盖壳体,覆盖壳体的侧缘与加强槽的周缘连接,覆盖壳体与第一连接部固定;第一连接部与第三连接部之间的部位以及覆盖壳体开设有工艺孔;不通过装配零件,直接与车身骨架传递冲击力,提高了冲击力的传递效率,加强槽与覆盖壳体形成鼓包,鼓包让第一连接部、第二连接部以及第三连接部之间形成整体,并在三者之间形成传力通道,增强了自身承受与传递冲击力的性能。
