    DETAILED DESCRIPTION

    [0045] In the Figures, the same reference numerals are used for identical and similar components, even if a repeated listing is omitted for reasons of simplicity.

    [0046] A spring link 1 according to the disclosure is described with reference to FIG. 1 to FIG. 5.

    [0047] A coordinate system is shown in FIG. 1 in order to define the position of the individual components in the construction of the spring link 1. The x-axis corresponds to the spring link longitudinal axis, the y-axis corresponds to the spring link transverse axis, and the z-axis corresponds to the spring link vertical axis.

    [0048] The spring link 1 has a link body 2, which includes a bearing section 3 on the wheel carrier side and a bearing section 4 on the vehicle body side.

    [0049] The link body 2 consists of two side wall profiles 5, 6, which are connected by an upper spring seat plate 7.

    [0050] The side wall profiles 5, 6 of the link body 2 are designed to be mirror-symmetrical to one another. The side wall profiles 5, 6 and the spring seat plate 7 include a high-strength steel material.

    [0051] Each side wall profile 5, 6 includes a side web 8 having an outwardly directed upper collar section 9 which extends in the longitudinal direction L of the side web 8. The side wall profiles 5, 6 are arranged parallel to one another at a distance in the y-axis. The spring seat plate 7 rests with lateral longitudinal edge sections 10, 11 on an upper collar section 9 of a side wall profile 5, 6. The spring seat plate 7 and the side wall profiles 5, 6 or upper collar sections 9 are materially bonded to one another.

    [0052] The upper collar sections 9 are repositioned or directed outwards from the side web 8 in the spring link transverse axis (y-axis).

    [0053] The upper collar sections 9, which extend along the upper side edges 12 of the side web 8, extend over the entire length of a side wall profile 5, 6. The collar sections 9 are directed outwards in relation to the vertical central longitudinal plane VMLE of the link body 2. The vertical central longitudinal plane VMLE also forms the plane of symmetry of the side wall profiles 5, 6.

    [0054] The link body 2 consists of three components, namely the two side wall profiles 5, 6 arranged parallel to one another at a distance and the spring seat plate 7 which extends transversely between the side wall profiles 5, 6 and connects the side wall profiles 5, 6.

    [0055] The lower side 13 of the link body 2 opposite to the spring seat plate 7 is open.

    [0056] Each side web 8 of a side wall profile 5, 6 includes an outwardly directed lower collar section 14 which extends in the longitudinal direction L of the side web 8. The lower collar sections 14 extend on the lower side edge 15 of the side web 8 over the length of a side wall profile 5, 6.

    [0057] The upper collar section 9 and the lower collar section 14 of a side wall profile 5, 6 merge into one another at a first front end 16 of the side wall profiles 5, 6 via an arced collar section 17. In this way, the upper collar section 9, the arced collar section 17, and the lower collar section 14 form an outwardly directed edge 18 which is continuous on three sides of a side wall profile 5, 6.

    [0058] The longitudinal edge sections 10, 11 of the spring seat plate 7 rest on the upper collar sections 9 and are joined thereto. Laterally, the longitudinal edge sections 10, 11 of the spring seat plate 7 protrude beyond the outer edges 19 of the collar sections 9.

    [0059] The spring seat plate 7 includes a bulge 21 that protrudes relative to a spring support surface 20. The bulge 21 is used as a centering and bearing orientation for a helical compression spring positioned on the spring support surface 20.

    [0060] The spring support surface 20 forming a spring seat lies above the side wall profiles 5, 6.

    [0061] The spring seat plate 7 includes an arced contoured recess 23 on its two end faces 22, each extending transversely between the side wall profiles 5, 6. The recess 23 is used to pass through add-on components such as stabilizers and shock absorber legs.

    [0062] Due to the recess 23, the end faces 22 of the spring seat plate 7 are forked or U-shaped having flange webs 24 extending in the longitudinal direction L of the side wall profiles 5, 6 and resting on the upper collar sections 9.

    [0063] The side wall profiles 5, 6 each include a first end section 25 on the wheel carrier side and a second end section 26 on the vehicle body side.

    [0064] In the bearing section 3 of the link body 2 on the wheel carrier side, two non-round openings 27 and 28 are provided in each of the first end sections 25 of the side wall profiles 5, 6. The first non-round opening 27 is an elongated hole. The second non-circular opening 28 has a trapezoidal configuration. The second non-round opening 28 is positioned on the side of the first opening 27 directed away from the front end 16 of the side wall profiles 5, 6. At the non-circular opening 28 having a trapezoidal configuration, an edge stop 29 is formed by a circumferential collar 30. The collar 30 is directed outward. The collar 30 therefore extends oriented in the same direction as the upper collar section 9 and the lower collar section 14 as well as the arced collar section 17.

    [0065] The non-round openings 27, 28 which are opposite to one another in the side wall profiles 5, 6 are arranged coaxially with one another. The two openings 27, 28 are configured and intended to cooperate with an eccentric adjustment device. The eccentric adjustment device includes actuating elements having cylindrical connecting elements which are guided through the openings 27, 28. By means of the eccentric adjustment device, the location and position of the bearing section 3 on the wheel carrier side are able to be adjusted relative to a wheel carrier.

    [0066] Inwards in the direction toward the spring seat plate 7, adjacent to the non-round openings 28, a bead 31 is provided in the first end section 25 of a side wall profile 5, 6. The bead 31 is formed in the transition 32 from the upper collar section 9 to the side web 8. The bead 31 extends in a triangular shape, directed downwards in the side web 8 to approximately its middle.

    [0067] The lower collar section 14 includes sections 33, 34 having different widths over its longitudinal course. In the middle sections 34, the collar section 14 is made wider than in the area of the end sections 25 and 26.

    [0068] Mounting holes 35 are provided in the lower collar sections 14. A stone chip protection is able to be fastened on the mounting openings 35. Here, the wider sections 34 of the lower collar section 14 function as a flange for assembly.

    [0069] The upper collar sections 9 also have a different width in their longitudinal course. In the middle longitudinal area, the upper collar sections 9 have the greatest width. The upper collar sections 9 taper towards the front end 16 and the arced collar section 17. In the second end section 26, the upper collar sections 9 also taper towards the free end 36.

    [0070] In the link body 2 or the side wall profiles 5, 6, bearing openings 37 for mounting a rubber bearing, bearing openings 38 for connecting stabilizer elements, and bearing openings 39 for connecting a shock absorber are also provided.

    [0071] The spring link 1 is completed by bearing components (not shown in the figures) and bearing or connection components for, for example, a rubber-metal bearing, stabilizers, a shock absorber, and a wheel carrier fastening, which includes an eccentric adjustment device.

    [0072] The two side wall profiles 5, 6, which are arranged at a distance from one another, are directly connected by the spring seat plate 7. Otherwise, a connection between the two side wall profiles 5, 6 is established indirectly via bearing components and/or connection components which are mounted on the bearing openings 37, 38, 39.
