Abstract: A tubular twist beam comprises a tubular body 20 including a U-shaped groove 22, tubular end sections 28, and transition sections 26 therebetween. The width w of the U-shaped groove 22 decreases continuously from each transition section 26 to a center point C of the tubular body 20 and is narrowest at the center point C to shift stress from the transition sections 26 to an area around the center point C. The tubular body 20 also includes depressions 24 along side walls 38 of each transition section 26 to direct stress to the underside of the U-shaped groove 22 and further balance the stress levels along the length of the tubular body 20. Thus, the tubular body 20 can be formed with a reduced thickness t and thus a reduced weight without sacrificing performance.

Abstract: A connecting rod is composed of two or more assembled shells made of a composite, open over the entire length of the connecting rod. The shells incorporate clevis joints for introducing stress at each of their ends. The shells are produced separately then assembled together to form a sealed section. Each shell is made from a material preimpregnated with long fibres. The production of each shell is simplified due to the overall shape of the shell as a simple curve, thus a shell may be produced industrially, for example, by thermoforming a flat composite preform. The two shells are assembled by simultaneous polymerization of the shells, by bonding, by welding, by riveting or any other assembly process or combination of assembly processes that are compatible with one another. The structural composite connecting rod obtained has very good mechanical properties, especially in compression, with a simple and economic production process.
