COUPLED TORSION BEAM AXLE STRUCTURE

摘要

PURPOSE: A coupled torsion beam axle structure is provided to exclude the degradation of durability while reducing the number of parts and simplifying the configuration thereof. CONSTITUTION: A coupled torsion beam axle structure comprises a section extension part(5). The section extension part forms a closed space(3) in the upper center of the cross section of a tubular beam(1). An axle structure has a triangle form. In the cross section of the tubular beam, an external side portion(7) is connected to an inner sidewall portion(9) while forming a closed curve. The external side portion forms the outside of the triangle form.
