REAR TWIST BEAM WITH BULGED MIDDLE SECTION

摘要

The suspension assembly (20) of torsion beam (22) includes that bottom (44) and side wall (46) have in the U-shaped cross-section and protrusion middle part (24) of opening. Torsion beam (22) includes end (56,58), and each of middle section (24) and changeover portion (60,62) are from the middle part (24) of an end (56,58). The torsion beam (22) of the width w) and height h increases along changeover portion (60,62) and middle part (24). The width w) and height h be greater than middle part (24) width w) and height h end (56,58). The protuberance middle section (24) of the cross-sectional area, usually 10% to 30% cross-sectional area is greater than end (56,58).
