Description

Reinforcing plate structure connecting automobile sub-frame and body

technical field

The utility model relates to a connection structure between an automobile auxiliary frame and a vehicle body, in particular to a structure for connecting a reinforcing plate between an automobile auxiliary frame and a vehicle body.

Background technique

As the intermediate buffer body connecting the body and the suspension, the sub-frame can reduce the vibration and noise transmitted from the engine compartment to the cab. The strength, rigidity and reliability requirements of the connection between the frame and the body are relatively high. In the current medium and low-end cars, bolts are generally used for rigid connection between the sub-frame and the body, and most of the existing automobile manufacturers are increasing the connection strength between the sub-frame and the body, or increasing the sub-frame itself. Make a fuss about the structural strength.

For example, a sub-frame mounting bracket disclosed in Chinese utility model patent CN202863552U adopts a V-shaped left mounting bracket and a right mounting bracket connected together to connect the sub-frame with the longitudinal beam of the vehicle body. Reinforce and fix so that the sub-frame is not easy to fall off after the collision of the car; another example is a car sub-frame reinforcement structure disclosed in the Chinese utility model patent CN203402242U, which is a body with curved ends. Bolt holes, the reinforced structure can prevent the subframe from cracking and improve the rigidity of the subframe. Although the above two technical solutions ensure the self-strength of the sub-frame and the connection strength between the body and the body, they ignore the absorption of the vibration energy transmitted between the sub-frame and the body, which will affect the driving comfort of the car. In high-end cars, although the sub-frame and the vehicle body can be connected by bushings to absorb vibration energy, it still exists the same as middle and low-end cars when the car collides, and it cannot absorb and buffer the collision energy, so that the collision impact The force is transmitted to the body through the sub-frame, causing the body to deform and threatening the safety of the driver.
