    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0028] FIG. 1 shows a detail of a perspective view of a chassis component 100 according to the prior art. In this example embodiment the chassis component 100 is a control arm made from sheet metal. The chassis component 100 has an essentially U-shaped cross-section. Accordingly, the chassis component 100 has two sidewalls 101 and 102 a distance apart from one another. Between the sidewalls 101, 102 is arranged a base surface 103, away from which the sidewalls 101, 102 extend.

    [0029] In the area of the first sidewall 101, the chassis component 100 has a first connecting feature 104 and opposite it, in the area of the second sidewall 102, there is a second connecting feature 105 for connecting with a mounting section (not shown here) of a chassis element. Such a chassis element can for example be in the form of a suspension strut. The two connecting features 104, 105 are in this case each in the form of through-going openings.

    [0030] Furthermore, on the first sidewall 101 the chassis component 100 has a first positioning and force introduction device 106. A correspondingly formed second positioning and force introduction device 107 is arranged on the second sidewall 102 but cannot be seen here. The positioning and force introduction device 106 or 107 is in each case formed as an independent and separate component, which in this example embodiment is connected to the sidewalls 101 or 102 by clinching.

    [0031] Thus, to form the positioning and force introduction device 106 or 107 a separate component must first be made and connected to the sidewall 101 or 102 in an independent working step. This results in undesired additional effort and undesired added cost.

    [0032] FIG. 2 shows in perspective a detail of a partially sectioned first chassis component 1 according to the present invention. In this example embodiment the chassis component 1 is in the form of a sheet-metal control arm. The chassis component 1 is designed to be connected to a mounting section 2 of a chassis element 3. The mounting section 2 is arranged in the area of a free end of the chassis element 3. In this case the chassis element 3 is in the form of a suspension strut.

    [0033] In this example embodiment the mounting section 2 consists of a joint 4. Accordingly, the mounting section 2 or joint 4 has an inner joint portion 5. The inner joint portion 5 extends out of the joint 4 on two sides remote from one another. Furthermore, at least in the area that extends out of the joint 4, the inner joint portion 5 has a cylindrical outer surface 6. The inner joint portion 5 has a through-going passage 7 which, in this example embodiment, is of hollow-cylindrical form.

    [0034] The mounting section 2 or chassis element 3 is shown here in an end position relative to the chassis component 1 and is arranged for mounting of the chassis element 3 on the chassis component 1. In the said end position the through-going passage 7 is aligned with a first connecting feature 8 and a second connecting feature 9 (not visible here) of the chassis component 1. In this case the two connecting features 8 and 9 are opposite one another.

    [0035] In addition, the chassis component 1 has a first positioning and force introduction device 10 and a second positioning and force introduction device 11 (not visible here). The structure and functional mode of the two positioning and force introduction devices 10, 11 are described in greater detail in the figures that follow.

    [0036] FIG. 3 shows a sectioned front view of the first chassis component 1 according to the invention as it is illustrated in FIG. 2. The chassis component 1 has an essentially U-shaped or U-like cross-section. The chassis component 1 has two sidewalls 12, 13 a distance apart from one another, and are connected to one another by means of a base surface 14 arranged between the two sidewalls 12, 13. The two sidewalls 12, 13 extend parallel to one another and essentially perpendicularly away from the base surface 14.

    [0037] The two positioning and force introduction devices 10, 11 serve for the automatic positioning of the mounting section 2 for the mounting of the chassis element 3 on the chassis component 1. In addition, during the intended use of the chassis component 1 in a chassis of a vehicle the positioning and force introduction devices 10, 11 serve to transmit forces introduced into the chassis component 1 by way of the chassis element 3 and the positioning and force introduction devices 10, 11. In this case the positioning and force introduction devices 10, 11 are each in the form of an integral part or section of the chassis component 1.

    [0038] In this example embodiment the positioning and force introduction devices 10, 11 are each formed by means of a cut in the material and by means of a deformation of an cut section of the chassis component 1. The positioning and force introduction devices 10, 11 are formed mirror-symmetrically relative to one another and shaped toward one another and into an inside space 15 of the chassis component 1. In that way the positioning and force introduction devices 10, 11 each form a projection for positioning the mounting section 2.

    [0039] The positioning and force introduction device 10 or 11 each has a curved or circular-section shaped contact area 16 or 17, respectively. The cylindrical outer surface 6 of the inner joint portion 5 rests on the said contact areas 16 and 17. This determines the final position of the mounting section 2 or chassis element 3 when mounting it on the chassis component 1. In this final position the through-going passage 7 and the two connecting features 8, 9 are aligned with one another, so that a separate fastening means (not shown here) can be passed through the two connecting features 8, 9 and through the through-going passage 7 in order to mount the mounting section 2 onto the chassis component 1.

    [0040] FIG. 4 shows a detail of a sectioned side view of the first chassis component 1 according to the invention, as illustrated in FIGS. 2 and 3. The aligned arrangement of the first connecting feature 8 with the through-going passage 7 can be seen clearly. Moreover, the circular-section shaped structure of the contact area 16 can be seen.

    [0041] FIG. 5 shows a sectioned front view of a second chassis component 18 according to the invention. The same features are given the same indexes as before. Accordingly, reference should be made to the previous description.

    [0042] In this example embodiment an additional fastening means 19 is shown, which extends through the two connecting features 8, 9 and the through-going passage 7 of the inner joint portion 5 in order to connect the mounting section 2 to the chassis component 18. The fastening means 19 in this example embodiment is in the form of a bolt secured by a separate nut 20. Such a fastening means can also be use with a chassis component according to FIGS. 2 to 4.

    [0043] In contrast to the embodiment according to FIGS. 2 to 4, in this example embodiment the positioning and force introduction devices 10, 11 are formed exclusively by deforming in each case a section of the chassis component 18. Here, there is no need to cut through the material. Thus, the positioning and force introduction devices 10, 11 are each in the form of embossed areas of the material of the respectively deformed section of the chassis component 18.

    [0044] FIG. 6 shows a detail of a sectioned perspective side view of the second chassis component 18 according to the invention, as in FIG. 5 but without the mounting section 2. Here, it can be seen clearly that the positioning and force introduction device 10 and, corresponding thereto, the positioning and force introduction device 11 (which cannot be seen in this case) are each formed as an essentially V-shaped embossment in the material of the sidewalls 12 and 13 respectively.

    [0045] FIG. 7 shows a sectioned front view of a third chassis component 21. The same features are again given the same indexes as before, and accordingly reference should be made to the previous description.

    [0046] In this example embodiment the positioning and force introduction devices 10, 11 are each formed by a deformed strip. In other words, the positioning and force introduction devices 10 and 11 are produced by deforming a section of the chassis component 21, namely a section of the sidewalls 12 and 13. The positioning and force introduction devices 10, 11 or the respective deformed strips are U-shaped in cross-section. Free end faces of the positioning and force introduction devices 10, 11, or of the correspondingly deformed strips, form the positioning and force introduction devices 10, 11 or the respective contact areas 16 and 17 for positioning the mounting section 2.

    [0047] FIG. 8 shows a detail of a sectioned perspective side view of the third chassis component 21 according to the invention illustrated in FIG. 7, without the mounting section 2. Clearly to be seen is the circular-section shaped contact area 16 for the interlocked holding of the cylindrical outer surface 6 of the inner joint portion 5 shown in FIG. 7.

    [0048] FIG. 9 shows a sectioned front view of a further chassis component 22 according to the invention. The same features are again given the same indexes as before, and accordingly reference should be made to the previous description.

    [0049] In this example embodiment the positioning and force introduction devices 10, 11 are in the form of an embossed area in the material of a section of the chassis component, namely a section of the sidewalls 12 and 13 respectively.

    [0050] FIG. 10 shows a detail of a sectioned perspective side view of the said further chassis component 22 according to the invention, without the mounting section 2. It can be seen clearly that the contact area 16 of the positioning and force introduction device 10 and, correspondingly, the contact area 17 (not visible) of the positioning and force introduction device 11 is straight, otherwise than in the previous example embodiments.
