Torsion beam type suspension

The invention provides a torsion beam type suspension which can improve the transverse force resisting capacity of a torsion beam. The torsion beam type suspension comprises two trailing arm parts, each trailing arm part comprises an elastic supporting part and an extending part, and the extending parts extend from the elastic supporting parts to the inner side of a vehicle body in the width direction; and the torsion beam is fixed on the extension part of each longitudinal arm part. 本发明提供一种扭力梁式悬架，可提升扭力梁抵抗横向力的能力。扭力梁式悬架包括：两纵臂部，每一所述纵臂部包括弹性支承部及延伸部，所述延伸部从所述弹性支承部往车身在宽度方向上的内侧延伸；以及扭力梁，固定于每一所述纵臂部的所述延伸部。
