Torsion beam suspension, also known as torsion beam semi-independent suspension, is a structure used in automotive rear suspension systems. It connects the two wheels via a torsion beam to reduce vehicle sway and maintain stability.
In a torsion beam suspension, there is no direct rigid axle connection between the two wheels. However, when one wheel encounters an uneven road surface, the torsion beam still causes some interference to the wheel on the other side. Therefore, strictly speaking, it is classified as a semi-independent suspension. To avoid interfering with other components, the torsion beam should twist within a certain range.
