一种车架总成结构
By setting mounting holes and reinforcing boxes on the longitudinal beams, combined with reinforcing sections, the contact area between the crossbeams and longitudinal beams is increased, solving the problem of stress concentration at the connection between the crossbeams and longitudinal beams in traditional frames, and achieving a more stable connection structure and improved vehicle comfort.

AI Technical Summary
In traditional car frames, stress concentration occurs at the connection points between crossbeams and longitudinal beams, making these connections prone to fatigue cracking and posing a safety hazard.
An installation port and a reinforcing box are provided on the longitudinal beam. The end of the crossbeam is fixedly connected to the longitudinal beam through the installation port. A reinforcing section is provided at the rear end of the front axle of the vehicle. The crossbeam passes through the reinforcing port and is fixed to the longitudinal beam to increase the contact area. The connection stability is enhanced by the sleeve structure. A reinforcing section is provided at the rear end of the front axle of the longitudinal beam to distribute stress.
The increased contact area between the crossbeams and longitudinal beams improves the stability and torsional stiffness of the connection structure, avoids stress concentration, reduces fatigue cracking at the connection points, and enhances vehicle comfort and NVH performance.
