Title:
TORSION BEAM
Document Type and Number:
WIPO Patent Application WO/2023/233585
Kind Code:
A1
Abstract:
A torsion beam (10) comprises a central section (11) and end sections (12) connecting to the central section (11) on both sides thereof. The torsion beam (10) has a tubular shape and extends in the longitudinal direction. The ratio S1/(L1×t1) is at least 1.4 but less than 10. S1 is the cross-sectional area of a transverse section of the central section (11) of the torsion beam (10) at the center in the longitudinal direction, the cross-sectional area including the internal space; L1 is the outer circumferential length of the transverse section; and t1 is the average wall thickness of the central section (11) of the torsion beam (10) at the center in the longitudinal direction.
