Problems solved by technology

[0004] The above optimization and improvement methods have the following deficiencies: Method 1 changing materials will increase the difficulty of the stamping process, and changing the thickness of the material will increase the weight of the vehicle; Method 2, if the reinforcement ribs are disorderly, cannot achieve the effect of absorbing the impact energy and alleviating the impact; the above two Neither method works well

Abstract

The invention discloses a reinforcing structure for connecting a rear suspension towing arm with a vehicle body, which comprises a rear longitudinal beam body connected with a rear section of a door sill, wherein a towing arm mounting reinforcing plate is arranged on the rear longitudinal beam body, and a nut seat for mounting the towing arm is arranged on the towing arm mounting reinforcing plate. A reinforcement structure for connecting a rear suspension towing arm to a vehicle body, By installing the trailing arm mounting stiffener at the rear side longitudinal member of the vehicle body, the rigidity and strength of the mounting point at the rear suspension trailing arm can be remarkably improved, and the local bending and torsional rigidity of the vehicle body can also be improved. The stamping forming process is simple, and the NVH performance and safety performance of the body in white can also be improved, which has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a reinforcing structure for connecting a trailing arm of a rear suspension with a vehicle body. Background technique [0002] Considering the comfort, bearing capacity and facing various complex driving conditions, most of the body structures of cars currently adopt load-bearing body structure design, and the rear longitudinal beam body and the trailing arm are installed with reinforcement plates as extremely important components of the lower part of the body. part. During the driving of the car (acceleration, cornering, sudden braking, etc.), the complex road condition information will generate a large impact force at the rear wheel of the car, and the impact load will be gradually transmitted to the car body, specifically to the installation point of the trailing arm of the rear suspension place. Therefore, if the structure here is unreasonable, it will af...
