PERFORATED TUBULAR TORSION BAR OF A MOTOR VEHICLE

摘要

The invention relates to a tubular torsion bar (10) of a motor vehicle chassis, comprising a tubular matrix (18) made of a composite material and at least one longitudinal implant (20, 22) made of fibres embedded in said composite tubular matrix (10), characterised in that the bar (10) comprises at least one longitudinal opening (24), the width (e) and length (L) of which determine resilient mechanical properties of said bar (10).
