Abstract

A torsion bar (1) used in automotive applications, is made up of sections (2) and (3). The combination of the separate sections gives the desired torsional characteristics to the torsion bar (1), by positioning the separate sections (2) and (3), at right angles to each other. The perpendicular sections produce a bar with a cross-like cross-section. Alternatively, the torsion bar (1) may have a star-shape cross-section, if the bar is made up of three (or more) sections (2), (6) and (7). Each section is made up of layers of reinforcement (14), and its shape may be hollow or solid. The overall thickness, the form, layout and design of the constituent parts determine the overall required stiffness characteristics of the torsion bar (1).
