Definitions
- the invention relates to a handlebar for a wheel suspension, comprising at least two bearing elements and a single-shell connecting element that connects the bearing elements together.
- Such links are used, for example, as wishbones in multi-link axles or wishbones in suspension strut axles of motor vehicles.
- Such handlebars a number of conflicting goals have to be reconciled.
- For a design that is as lightweight as possible it is desirable to design the handlebars with thin walls or to use lightweight materials.
- sufficient load-bearing capacity must always be ensured.
- it must be taken into account that the handlebar in an installed state in a motor vehicle is subjected to complex loads during driving operation, with individual areas being subjected to greater stress, others being subjected to less stress.
- the aim is therefore to adapt the geometry of the handlebar to the loads that occur.
- limits here particularly due to the manufacturing technology options. These are not only in the technological area. Rather, in the case of series production, economic considerations must be taken into account, which are reflected in the requirement for production to be as simple and inexpensive as possible.
- a handlebar designed as a cast part is disclosed, for example, in DE 199 23 699 A1.
- This known handlebar is formed in one piece and consists of a substantially flat carrier that is thickened at its edges. In cross-section, this results in a double-T profile that has a high degree of bending rigidity.
- the casting process used to manufacture this handlebar also enables bearing elements in the form of bearing eyes to be made in one piece to train the flat web. This creates a handlebar that can be easily manufactured in large quantities.
- this handlebar is made of light metal.
- the use of light metal results in higher material costs compared to a steel handlebar.
- steel or cast iron is used instead of light metal, this leads to a significant increase in weight.
- the invention intends to create a handlebar of the type mentioned at the outset, which can be produced simply and inexpensively with a low weight.
- a handlebar of the type mentioned in which the connecting element comprises a one-piece web and at least one belt which is fastened to an edge of the web, the web being attached to the belt essentially at right angles.
- the open shape also results in a somewhat more compact design. It is also possible to manufacture the individual parts of the connecting element from different materials.
- the connecting element has a T-profile or a double-T profile, at least in sections, in cross section.
- the connecting element can, at least in sections, also be designed as an L-profile or U-profile.
- the belt or belts can be continuous or interrupted. In any case, however, the belts are preferably arranged such that they extend as far as the bearing elements, so that a high degree of rigidity is achieved in the area around the bearing elements, that is to say at the bearing points. Furthermore, the width of the straps can be constant or different along the same.
- a belt is fastened in the region of the bearing elements on both edges of the web. This results in a double T-profile or a U-profile, for example, in cross-section at the relevant bearing point.
- the web and / or the straps each have an essentially constant wall thickness.
- the individual parts of the connecting element are particularly easy to manufacture.
- the web can be designed as a substantially flat plate.
- the straps are preferably designed as narrow, band-shaped strips.
- the web and the belts are preferably made from a metallic material, in particular from steel or light metal. Additional weight savings can be achieved, especially when using light metal.
- the web can be designed as a cast part or forged part.
- the web is preferably produced as a substantially flat sheet metal part.
- the web and / or the straps from a plastic or a fiber composite material.
- the handlebar has two bearing elements which are welded to the single-shell connecting element.
- the connecting element is bent in an arc shape.
- the belt or belts are welded to the web.
- the web has a roughly triangular basic shape, the corners of which are designed as bearing points and / or fastening points, all edges of the web between the bearing points and / or fastening points being provided with belts.

- FIG. 2 shows a view from above of the wishbone from FIG. 1
- FIG. 3 shows a side view of the wishbone from FIG. 1
- FIG. 4 shows a further side view of the wishbone from FIG. 1,
- FIG. 5 shows a section through the connecting element of the wishbone from FIG. 1 along the line V-V
- FIG. 6 shows a second embodiment of a wishbone according to the invention in a spatial representation
- FIG. 7 shows a section through the connecting element of the wishbone from FIG. 6 along the line Vll-Vll,
- FIG. 8 shows a further section through the connecting element of the wishbone from FIG. 6 along the line Vlll-Vlll,
- FIG. 9 shows an example of a further cross-sectional shape of the connecting element of the wishbone from FIG. 6, and in
- Figure 10 shows another example of a further cross-sectional shape of the
- the first exemplary embodiment in FIGS. 1 to 5 shows a wishbone 1 for a wheel suspension of a motor vehicle.
- the control arm 1 has two bearing elements 2 and 3, which are connected to one another via a single-shell connecting element 4.
- the bearing elements 2 and 3 are each designed as bushings with a through opening.
- the through opening of the bushings is essentially perpendicular to the main extension plane of the connecting element 4.
- the connecting element 4 is bent in an arc shape with respect to an axis A connecting the bearing elements 2 and 3, in such a way that at least one central one The area between the bearing elements 2 and 3 is free of material.
- the single-shell connecting element 4 comprises one in the first embodiment in the main plane of extension of the connecting element 4 arranged web 5, which is designed here as an essentially flat, one-piece plate and essentially determines the basic shape of the connecting element 4 when viewed from above. Accordingly, the web 5 has an arcuate, cranked basic shape. Opposing end sections of the elongate web 5 are each formed like pliers in order to partially encompass the bearing elements 2 and 3.
- the connecting element 4 comprises a belt 6 which is attached to an edge of the web 5.
- the belt 6 is designed as a narrow, band-shaped strip with a constant width. The width is somewhat less than the length of the bearing elements 2 and 3.
- the belt 6 runs continuously on the inside of the crank of the web 5 from one bearing element 2 to the other bearing element 3 and nestles closely against the outer edge of the web 5 on.
- the width direction of the belt 6 is perpendicular to the main plane of extent.
- the web 5 is attached to the belt 6 at right angles.
- the opposite, outer edge of the web 5, however, is not stiffened with a belt. This results in a T-profile in cross section for the connecting element 4, as shown in FIG. 5.
- FIG. 5 also shows that the belt 6 has a greater wall thickness than the web 5.
- Both parts of the connecting element 4 are designed as sheet metal parts, each of which has a simple shape and is therefore inexpensive to produce.
- the web 5 here is a simple plate that only needs to be cut out or punched out of a metal sheet.
- the bearing elements 2 and 3, the web 5 and the belt 6 are welded together. This can be done, for example, as described below: First, the bearing elements 2 and 3 are connected to the end sections of the web 5 via welds 7 and 8. The belt 6 is then attached and welded to the web 5 from above and below by means of further weld seams 9 and 10. Finally, the ends of the belt 6 are connected to the bearing elements 2 and 3 via welds 11 and 12.
- the web 5, which can also be a sheet metal part, is provided on its two outer edges with a belt that extends continuously from one bearing element 2 to the other other bearing element 3 extends.
- the bearing elements 2 and 3 are preferably first welded on before the belts are fastened.
- the belt 6 is shown with a uniform width and constant wall thickness in the first embodiment.
- the belt 6 can be easily produced, for example from tape material.
- the width and wall thickness of the belt 6 can also be adapted to the stresses that occur. This applies both to the formation of the connecting element 4 with a T-profile and with a double-T profile. It is also possible to interrupt one or both belts. However, at least one strap is always provided there to stiffen the areas around the bearing elements 2 and 3.
- the web 5 can be displaced in height in relation to the belt or belts, which in extreme cases results in an L-profile or U-profile, as is shown by way of example in FIG. 10.
- the second exemplary embodiment in FIGS. 6 to 8 shows a further control arm 21 with two bearing elements 22 and 23 and an additional fastening point which are connected to one another via a single-shell connecting element 24.
- the pivot axes Bi and B 2 of the first bearing element 22 and second bearing element 23 run essentially parallel to the main extension plane of the connecting element 24.
- the two pivot axes B are . and B 2 aligned approximately coaxially to each other.
- the connecting element is somewhat retracted between the bearing elements 22 and 23, thereby creating a free space for the front bearing.
- the connecting element 24 has a roughly triangular basic shape, which is essentially defined by a one-piece web 25.
- Belts 26, 27 and 28 are attached to the edges of the web 25 for stiffening and each extend between the bearing or fastening points.
- the straps 26, 27 and 28 are also here consistently formed as narrow, ribbon-shaped strips.
- the straps 26, 27 and 28 each have a constant thickness.
- the web 25 is at right angles to the belts 26, 27 and 28.
- a belt 26 located in front of its installation situation on a motor vehicle is designed with a thinner wall thickness than a belt 27 lying opposite it, ie a belt 27 located at the rear.
- the latter has approximately the thickness of an inner belt 28 which extends between the two bearing elements 22 and 23 ,
- the wall thickness of the web 25 corresponds approximately to the wall thickness of the front belt 26.
- any combination of thicknesses is possible depending on the load on the wishbone 21.
- the width can also be varied.
- Both the belts 26, 27 and 28 and the web 25 are formed as sheet metal parts and welded to one another in a similar way to the first exemplary embodiment.
- an arcuate recess is provided on the belts 26 and 28 for fastening the first bearing element 22, which is designed in the form of a bushing with end-side collar 33, and partially engages around the bushing below the respective collar 33.
- the narrower, front belt 26 has a widened section 29 in the area around the bearing point of the first bearing element 22.
- control arms 1 and 21 described above are each in sheet metal construction formed, preferably sheet steel parts are used here.
- individual elements of the respective control arm or the entire control arm can also be made of light metal, in particular an aluminum or magnesium alloy.
- the web 5 or 25 can be a cast or forged part on which the bearing elements are integrally formed.
- plastics and fiber composites for the web and the belts.
- a single-shell connecting element which is composed of a one-piece web and belts, results in a reduction in weight and a reduction in material costs compared to a double-shell construction.
