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).
Description
Automotive torsion bar made up of sections.
DESCRIPTION
The present invention relates to a torsion bar made up of sections, that can be used in a suspension of a car.
The current application of a torsion bar in vehicles, and especially cars, involve metal bars of circular cross-section, that are solid, made of one piece.
The object of the present invention is the action of a single circular torsion bar to be performed by an array of sections joined together. Thus, substituting the conventional torsion bar with a "torsion bar in sections", that can be made lighter and can be tailored depending on the required stiffness characteristics and dimensions to fit a specific suspension module.
According to the invention, the objective is achieved by the use of separate multiple supplementary sections joined together, so that the resulting torsion bar can be made lighter and smaller, according to tailored design and packaging needs, as defined in independent claim 1. The dependent claims define preferred embodiments of the invention.
In the following, a preferred embodiment of the invention will be discussed in more detail, with reference to the accompanying drawings.
The invention will be made conceivable with reference to the designs that accompany the present description, in which certain proposed industrial applications of the invention are shown.

Fig.1 - Fig.11 show a preferred embodiment of the invention. While this particular embodiment will be described in detail below, several modifications will be appreciated by a person skilled in the art, so that the invention shall not be interpreted in a limited manner, referring to the description and the drawings. Rather the invention is defined by the appended claims.
Referring to a selected indicative example of industrial application of the invention, a number of the main sections and components of the device are listed below.
More specifically, the basic parts of the invention are the following :
1. Torsion bar made up of sections.
2. Inner constituent part (receptor), in a bar of cross-like cross-section.
3. Inner constituent part (supplementary), (in a bar of cross-like cross-section).
4. Left outer part.
5. Right outer part.
6. Inner part (supplementary), (in a bar of star-shape cross-section).
7. Inner part (second supplementary), (in a bar of star-shape cross-section).
8. Coupling end to the left part (4), of the inner constituent part (2), (3), (6), (7).
9. Coupling end to the right part (5), of the inner constituent part (2), (3), (6), (7). 10. Cavity space of the inner constituent part (2), (3), (6), (7).
11. Coupling aperture (for reception) of the inner constituent part (2).
12. Coupling gap (for reception and coupling) of the inner constituent part (2).
13. Coupling end on the outer part (4), (5).
14. Reinforcement layer.
In Figs 1-11 , reference numeral 1 designated the automotive torsion bar made up of sections.
According to the preferrred embodiment shown, the torsion bar in sections (1 ), shown in Fig 1 , is made up of two inner parts (2) and (3), and two outer parts (4) and (5), shown in Fig 2.
The inner part (2) is represented in Fig 3. Its left end is shaped at ts coupling edge (8). Its right end is shaped at its coupling edge (9). (See also Fig 10)
These edges allow the joining of the inner constituent parts (2), (3) to the outer parts (4) and (5) via couplings of the form of coupling (13). See Fig 6.
The inner part (2), (Fig 3), allows the joining with the inner part (3), (the supplementary part) via the gap (12) and is fitted at the aperture (11), into position. The cavity spaces (10) are created inside the part (2), depending on the desired levels of torsional rigidity of the torsion bar (1 ), that is created. (See Fig 3) Corresponding cavity spaces (10) are formed in the supplementary inner part (3).
Alternatively, the inner part (2), (having no cavity spaces (10)) is solid, (Fig 4), and has only one gap (12) that allows the positioning of the two constituent parts (2) and (3) to form the bar (1). The aperture (11) and the gap (12) allow the complementary positioning of the two constituent parts (2) and (3). (See Fig 5, Fig 7).
The overall width of each constituent part ((2), (3)) depends on the overall torsional characteristic of the torsion bar (1). Thicker parts (2) and (3) are shown in Fig 6. These are arrived at by additional layers of reinforcement (14), shown in Fig 8. The shape and profile of the reinforcement layers (14), as well as their positioning on the constituent parts (2) and (3) is determined by the desired torsional rigidity of the bar
(I) and the stress and fatigue analysis of the dynamics of the loading characteristics of the bar (1). The shape, size and positioning of the layers of reinforcement (14) and the complementary sizes and shapes of coupling aperture (11 ) and gap (12) featured on the inner parts (2) and (3), determine the overall shape and characteristics of the resulting bar (1 ). In this case, two perpendicular inner parts are joined together at right angles to each other. The resulting object has a cross-like cross-section. (Fig 9).
Alternatively, the inner part (3) can be substituted by two (or more) inner parts (supplementary part (6), second supplementary part (7)), and joined to the first inner part (2), that can accommodate the joining, through gap (12), at the aperture
(I I) . In this case the bar (1), has a star-shape cross-section. (Fig 11).
The overall thickness, the form, layout and design, materials and methods of joining of the constituent parts determine the overall stiffness characteristics of the torsion bar (1 ).
The shape, profiling and joining of the inner constituent parts (2), (3), (6), (7), the profile, positioning and the number of the layers of reinforcement (14), and the form, positioning and the geometric characteristics of the cavities (10), the aperture (1 1) and gap (12), are determined by the required torsional stiffness and fatigue endurance of the bar (1 ).
Typical forms of inner elements (2) and (3), with coupling end forms (8) and (9) are shown in Fig 10.
