TORSION BEAM OF A CTBA(COUPLED TORSION BEAM ALXE) SUSPENSION DEVICE CAPABLE OF ADJUSTING THE STRENGTH OF A ROLL BY CONTROLLING THE NUMBER OF BEADS

摘要

PURPOSE: A torsion beam of a CTBA suspension device is provided to improve the strength and the durability of a roll of a torsion beam axle by forming the shape of a torsion beam into V shape and comprising one or more beads in the longitudinal direction of a torsion beam axle.;CONSTITUTION: A torsion beam(100) of a CTBA suspension device is formed into V shape. A torsion beam comprises one or more beads(110). The beads increases the strength and the durability of a roll by improving a torsion constant and a section modulus of a welding portion of a trailing arm and a torsion beam.;COPYRIGHT KIPO 2012
