Abstract
A torsion bar (1) used in automotive applications, is made up of inner sections (2) and (3). The joining 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 (1) is made up of three (or more) sections (2), (6) and (7). Each inner section is made up of layers of reinforcement (14), and its shape may be hollow or solid, depending on the size and positioning of the cavity space (10). The overall thickness, the form, layout and design of the inner constituent parts determine the overall required stiffness characteristics of the torsion bar (1). The shape, profiling and joining of the inner constituent parts (2), (3), (6), (7), the profile and positioning of the layers of reinforcement (14), and the form, positioning and the geometric characteristics of the cavity spaces (10), the aperture (11) and gap (12), are determined by the required torsional stiffness and fatigue endurance of the bar (1).
