What is a torsion beam used for in a suspension system?

A torsion beam in a suspension system is primarily used to provide stability and support. This component is designed to act as a structural beam that can resist twisting forces while maintaining the vehicle's alignment during various driving conditions. By linking two wheels together, it helps to improve the overall handling of the vehicle, especially during cornering or over uneven surfaces. The design allows it to absorb impacts and distribute loads effectively, contributing to vehicle stability and support.

Torsion beams typically offer a balance of performance and comfort; however, their main function is focused on improving stability rather than solely enhancing comfort or reducing weight. While these beams can influence ride height to some degree or help in reducing vehicle weight, their essential role remains in providing structural support and maintaining stability through the suspension system.
