Description

Technical Field

[0001] This utility model relates to the field of automotive suspension, specifically a reinforcement structure for automotive chassis suspension. Background Technology

[0002] The suspension system refers to the entire support system composed of springs and shock absorbers between the vehicle body and tires. The function of the suspension system is to support the vehicle body and improve ride comfort; different suspension settings will give the driver different driving experiences. Some existing car suspensions use a torsion beam for support in the middle. The torsion beam suspension is a type of rear suspension that uses a torsion beam to balance the vertical movement of the left and right wheels, reducing vehicle sway and maintaining vehicle stability. The torsion beam of current car chassis suspensions is usually made of a single piece of metal, providing sufficient reinforcement and protection. However, if the torsion beam breaks due to an impact, the entire suspension becomes unusable, shortening its lifespan. Utility Model Content
