Problems solved by technology
[0004] However, when the existing engine load-bearing beam is in use, if the front of the vehicle collides, after the collision, the plate-shaped connectors connected to both sides of the automobile weighing beam will transmit the impact force to the assembly parts connected to it. Bolts or rivets are assembled on the body frame, and the impact force they transmit is limited, so a connector structure is needed to enhance its own performance of bearing and transmitting impact force

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.
Description
technical field [0001] The invention relates to an engine load-bearing beam, in particular to a connection structure for an engine load-bearing beam. Background technique [0002] The engine load beam is located at the bottom of the engine, used to carry the engine and connect with the chassis to participate in the strength of the entire body. The two ends of the existing engine load-bearing beam will be fixedly connected to an assembly part below the A-pillar of the car through a plate-shaped connector, and the assembly part is assembled on the body frame by bolts or rivets. [0003] In the prior art, the load-bearing beam of the engine can refer to a kind of automobile engine load-bearing beam disclosed by the Chinese patent whose patent announcement number is CN203438833U, including the left component, the middle beam, the right side component, the left side component, the middle beam and the right side The components are integrally formed as a whole, with waist-shaped h...
