Description

Technical Field

[0001] The present invention relates to a chassis component for a motor vehicle according to the preamble of claim 1, for example as an aftermarket addition. Background Technology

[0002] This type of chassis component, such as the rear axle, specifically the crossbeam of such a axle, has a device on the mounting members (such as spring links and tie rods) for connecting the control arms for adjusting the toe and camber of the vehicle wheels. The device typically includes an eccentric disc that is torsionalally rigidly connected to the connecting bolts for connecting the control arms, whereby the eccentric disc is assigned a limiter against which it rolls or slides when the connecting bolts are adjusted to adjust the toe and camber.

[0003] In the prior art, the limiting element for the eccentric disk is achieved by at least one welded additional element, for example, in the form of parallel spaced square steel profiles or U-shaped steel parts, or by a slotted opening (see, for example, DE 20 2019105 455 U1). Figure 1 And US 2013 / 0193660 A1 Figure 3 and Figure 7 However, these known solutions are not satisfactory. This is because welding on two parallel square steel profiles spaced a certain distance apart is time-consuming and difficult or error-prone in terms of precisely aligning the square steel profiles relative to each other. In the case of eccentric retainers achieved by welding on U-shaped steel components, the legs of the steel components are already aligned with each other, but the problem with such eccentric retainers is their high risk of corrosion from exposure to water and salt.

[0004] For slotted openings, there are specific issues with the potential for unintended crack formation or crack propagation in the base material of the chassis components. Furthermore, relatively more effort is required to meet the maximum permissible tolerances regarding the shape and size of the slotted opening. Additionally, during the assembly of the connecting bolts, i.e., when tightening the screw connection, the slotted opening may be pressed in, causing a loss of its restraining function.

[0005] Based on the above, the present invention aims to produce a chassis component of the type mentioned at the beginning, whose eccentric limiting element is characterized by a lower risk of corrosion and can be manufactured cost-effectively without the risk of cracking. Summary of the Invention

[0006] This objective is achieved by a chassis component having the features of claim 1. Preferred and advantageous embodiments of the chassis component according to the invention are set forth in the dependent claims.

[0007] The chassis component according to the invention includes a mounting member having at least one elongated hole for receiving a connecting bolt for connecting a control arm and at least one limiting member for torsional rigid connection or connectable to the connecting bolt of an eccentric disc, wherein the limiting member is formed of a metal piece, preferably a one-piece metal piece, which is manufactured separately from the mounting member and is connected to the mounting member and has at least two spaced-apart attachment portions and a connecting portion connecting the attachment portions to each other, wherein these or at least two of the attachment portions define a limiting surface for the eccentric disc. The suspension component according to the invention is characterized in that the connecting portion is preferably angled or offset relative to the attachment portions, such that the connecting portion is at least partially spaced relative to the mounting member.

[0008] The limiting element or corresponding metal part may also be referred to as an eccentric limiting element. The functional surfaces used as limiting surfaces for the eccentric disk preferably face each other, wherein the corresponding functional surfaces form an angle of approximately 90° to 135° with the surface of the mounting part.

[0009] The formation or bending of the contact portion of the connecting part relative to the metal part (eccentric retainer) and the resulting spacing of the connecting part relative to the mounting part reduce the contact surface of the metal part on the mounting part, and thus significantly reduce the corrosion risk of the eccentric retainer. This is particularly advantageous for the connection of the spring control arm, as the spring control arm is typically mounted at a low point on the wheel suspension, where the eccentric retainer associated with the spring control arm is subjected to high loads from water and salt, especially in winter.

[0010] The connecting portion is preferably angled or offset relative to the attachment portion of the metal part by forming an operation.

[0011] Furthermore, the design of the eccentric limiting member according to the invention creates additional mounting space below the formed (reshaped), for example, angled or offset connecting portion, for connecting another component to be attached to the mounting member, such as a tie rod bracket.

[0012] Therefore, an advantageous embodiment of the chassis component according to the invention provides that the connecting portion of the metal part (eccentric limiting part) engages above another component, preferably a metal part, connected to the mounting component.

[0013] A further embodiment of the chassis component according to the invention is characterized in that the distance between the connecting portion and the mounting member is at least partially greater than the thickness of the metal member, preferably at least 1.5 times the thickness of the metal member, and particularly preferably at least 2 times. In this way, the reduction of the contact surface of the metal member on the mounting member can be reliably ensured to a large extent, because the loss of the distance set in the invention due to the occasional occurrence of dirt deposition (which can close the distance or seal the corresponding gap) is almost non-existent in this embodiment.

[0014] The metal part defining the eccentric limiting member according to the invention is preferably substantially U-shaped, wherein the attachment portion is defined by the legs of the U-shaped metal part. Correspondingly designed eccentric limiting members can be manufactured in a simple and cost-effective manner.

[0015] The attachment portions of the metal parts are preferably elongated; therefore, they can also be referred to as elongated attachment portions of a one-piece metal part. Thus, the connecting portions that connect the attachment portions of the metal parts to each other can also be referred to as the portions of the metal parts that connect the elongated attachment portions of the one-piece metal parts to each other.

[0016] Another embodiment of the invention provides that the connecting portion is at a single angle relative to the attachment portion, preferably an elongated attachment portion. In this embodiment, the angled portion defines a tapered or wedge-shaped gap with the mounting member. The corresponding bending of the connecting portion or metal part can be achieved in a manner that is gentle on the material and does not pose a risk of cracking.

[0017] According to a preferred embodiment, this effect can be particularly achieved if the angled connecting portion and the attachment portion define an obtuse angle, which is in the range of 130° to 175°, preferably in the range of 140° to 160°.

[0018] Alternatively, another embodiment of the invention provides that the connecting portion and the attachment portion define an acute angle, which is in the range of 5° to 25°, preferably in the range of 8° to 15°.

[0019] According to another embodiment of the invention, the angled connecting portion has a flat surface on its side opposite to the mounting member, which is connected to the surface of the attachment portion opposite to the mounting member via a curved region of the metal member. The radius of curvature of the curved region of the metal member (eccentric retainer) is, for example, in the range of 2.5 to 6 times the thickness or average thickness of the metal member or the attachment portion.

[0020] Another advantageous embodiment of the invention is characterized in that the metal part (used as an eccentric limiting member) is stepped-bent, such that the connecting portion is at least partially offset relative to the attached portion. The correspondingly designed eccentric limiting member is characterized by relatively small space requirements, thus reducing the risk of corrosion.

[0021] According to a preferred further improvement, this effect can be achieved, particularly if the connecting portion is offset parallel to or at least partially parallel to the attachment portion. Alternatively, the connecting portion may also be offset at an angle or at least partially at an angle relative to the attachment portion.

[0022] According to another advantageous embodiment of the invention, the attachment portion of the metal part rests in contact with the mounting member, such that there are at least two contact surfaces, wherein the connecting portion connecting the attachment portion has a lower free surface that faces at least partially towards the mounting member, the lower free surface being larger than the sum of the contact surfaces. The relatively small sum of the contact surfaces results in a correspondingly reduced risk of corrosion for the eccentric retainer, which can also be quickly aligned and reliably secured to the mounting member.

[0023] Another advantageous embodiment of the invention is characterized in that the corresponding attachment portion of the metal part has a width or average width that is at least twice, preferably at least three times, the thickness of the metal part. This allows for optimization of the bending stiffness of the eccentric limiting member with low weight or minimal weight increase.

[0024] According to another advantageous embodiment of the invention, the attachment portion of the metal part is connected to the mounting part by fillet welds arranged on opposite edges of the attachment portion. This design facilitates a particularly compact and stable design of the eccentric retainer. Specifically, it is advantageous if the corresponding fillet weld is not longer than the maximum width of the oblong hole, whereby the long axis of the oblong hole defines a reference line, to which the fillet weld is aligned, and thus preferably arranged between tangents parallel to the long axis of the oblong hole. This allows for the transmission of force at the eccentric retainer to reduce or homogenize the stress in the mounting part assigned to the eccentric retainer.

[0025] As an alternative to fillet welding, the eccentric retainer according to the invention can also be connected to an added component, such as a beam, by another type of welding (e.g., resistance welding, specifically projection welding). Another advantageous embodiment of the invention provides that the metal component connected to the mounting has a coating produced by cathodic dip coating, which is already formed after the metal component has been connected to the bracket. This further reduces the risk of corrosion of the eccentric retainer. In this case, the cathodic dip coating is preferably an extended cathodic dip coating.

[0026] According to another advantageous embodiment of the invention, the connecting portion, angled or offset relative to the attachment portion, has a fastening structure, such as in the form of a lug or eyelet. The fastening structure preferably includes a fastening opening, such as a fastening hole. The fastening structure can be formed at any point on the connecting portion. Preferably, the fastening structure or fastening opening is located within a central length or arc length range of the connecting portion. The fastening structure or fastening opening is used to secure or connect fastening devices for fastening one or more pipelines and is designed accordingly. The fastening device can be, for example, a mounting element, a clamp, an expansion rivet, or a rivet nut. The pipeline to be fastened to the fastening device can be, for example, a pneumatic line, a hydraulic line, or an electrical line. In this embodiment, the eccentric limiting member according to the invention has multiple functions. Attached Figure Description

[0037] Figure 1 Sections of a chassis component for a motor vehicle are shown. The chassis component is, for example, an aftermarket addition 1 in the form of a crossbeam or a subframe with a crossbeam (see [reference]). Figure 10The chassis component has a mounting member 1.1 for movably, specifically pivotally, mounting a control arm (not shown here) for the suspension of the vehicle wheels. The end of the control arm connected to the mounting member 1.1 typically has two aligned bearing eyes, in which bearing bushings are securely held. The bearing bushings are typically designed as rubber-metal bushings.

[0038] Mounting element 1.1 or post-installation element 1 is made of sheet metal, preferably steel, which has been formed into a specific component geometry. Post-installation element 1 is preferably made of high-strength steel, such as multiphase or complex-phase steel, having a tensile strength of at least 800 MPa and a yield strength of at least 680 MPa. The sheet thickness of mounting element 1.1 or post-installation element 1 is, for example, in the range of 1.5 mm to 3.5 mm, preferably in the range of 1.5 mm to 2.5 mm.

[0039] Mounting element 1.1 is, for example, fork-shaped. Through holes 2 are provided in spaced portions or legs of mounting element 1.1, these spaced portions or legs being aligned with each other and used to receive connecting bolts (not shown here) for connecting the control arm. The connecting bolts extend through the aforementioned bearing bushing of the control arm, such that the attachment bushing is rotatably mounted on the connecting bolts. At least one of the aligned through holes 2 is designed as an elongated oval hole. Preferably, mounting element 1.1 includes at least two such through holes 2, these through holes being designed as elongated oval holes to receive the connecting bolts. By adjusting, specifically moving, the connecting bolt along the longitudinal axis 2.1 of one or more elongated oval holes 2, the camber (i.e., the tilt of the wheel plane relative to the vertical direction) and toe-in of the associated vehicle wheels can be adjusted via the control arm. For this purpose, the connecting bolt is provided with an eccentric disc (not shown) that is torsionalally rigidly connected to the connecting bolt. For example, the connecting bolt has a longitudinal groove in which the eccentric disc securely engages with a radially inwardly projecting protrusion at its through opening. Alternatively, the eccentric disc and connecting bolts can also be welded together.

[0040] Mounting member 1.1 has at least one limiting member for an eccentric disk, which is torsionalally rigidly connected or connectable to a connecting bolt. The limiting member (eccentric limiting member) is formed of a metal part 3 manufactured separately from mounting member 1.1 and connected to mounting member 1.1. Metal part 3 has at least two attachment portions 3.1, 3.2, which are formed as one piece with each other, and two of the at least two attachment portions (3.1, 3.2) have functional surfaces facing each other, which serve as limiting surfaces 3.11, 3.21 for the eccentric disk. Attachment portions 3.1, 3.2 are preferably elongated; each attachment portion 3.1, 3.2 is preferably longer than its width.

[0041] exist Figures 1 to 3 In the embodiment of the present invention shown, it can be seen that the connecting portion 33, which connects the attachment portions 3.1 and 3.2 of the metal part (eccentric limiting member) 3 to each other, is formed (reshaped) or angled relative to the attachment portions 3.1 and 3.2, such that the connecting portion 3.3 is at least partially spaced apart from the mounting member 1.1. Therefore, the connecting portion 3.3 itself does not directly contact the mounting member 1.1 or the post-installed part 1.

[0042] The metal part 3 is preferably substantially U-shaped, wherein the attachment portions 3.1, 3.2 are defined by the legs of the U-shaped metal part 3. Figures 1 to 3 The metal part 3 shown is stepped, for example, such that the arcuate connecting portion 33, which connects the attachment portions 3.1 and 3.2 to each other, is at least partially offset relative to the attachment portions 3.1 and 3.2. For example, the connecting portion 3.3 is partially offset parallel to the attachment portions 3.1 and 3.2. In other words, the metal part 3, which serves as an eccentric limiting member, has a shoulder.

[0043] The attachment portions 3.1 and 3.2 of the metal part 3 rest in contact with the mounting member, creating at least two contact surfaces 3.14 and 3.25. The connecting portion 3.3, which connects the attachment portions 3.1 and 3.2 to each other, has a free surface 3.31 on its lower side that faces the mounting member 1.1 at least partially. This free surface is larger than the sum of the contact surfaces 3.14 and 3.25. The lower free surface 3.31 is, for example, at least 5% larger than the sum of the contact surfaces 3.14 and 3.25, preferably at least 10%. Furthermore, the respective attachment portions 3.1 and 3.2 of the metal part 3 have a width B or an average width B', which is, for example, at least twice, preferably at least three times, the thickness D of the metal part 3. Specifically, the width B or average width B' of the respective attachment portions 3.1 and 3.2 can be in the range of 8 mm to 20 mm, while its thickness D or the thickness D of the metal part 3 is in the range of 2.5 mm to 8 mm.

[0044] The metal part 3, used as an eccentric limiting member, is securely connected to the post-attached part 1 because the attachment portions 3.1 and 3.2 of the metal part 3 are preferably connected to the post-attached part 1 via a welded joint (e.g., a fillet weld 4 formed on the mounting part 1.1 on the post-attached part 1). The welded joint 4 is preferably arranged on the opposite edges of the attachment portions 3.1 and 3.2 of the metal part 3. Furthermore, in Figure 1 Chinese combination Figure 4 It can be seen that the corresponding fillet weld 4 is not longer than the maximum width B of the oblong hole 2. L The long axis 2.1 of the oblong hole 2 defines a reference line, and the fillet weld 4 is arranged aligned with this reference line. The fillet weld 4 is preferably located between tangents T1 and T2 of the oblong hole 2, which are parallel to the long axis 2.1 (see [reference]). Figure 4 ).

[0045] Because the connecting portion 3.3 of the metal part 3 is angled relative to the attachment portions 3.1 and 3.2, the metal part 3 rests against the mounting part 1.1 or the post-attachment 1 with a reduced contact surface, thereby reducing the risk of corrosion. To further reduce the risk of corrosion, the metal part 3, which is securely connected (preferably welded) to the mounting part 1.1 of the post-attachment 1, is provided with an anti-corrosion coating, for example, a coating produced by extended cathodic electrophoretic coating. This coating is formed after the metal part 3 has been connected to the post-attachment 1 at the mounting part 1.1.

[0046] Figure 4 and Figure 5 Another embodiment of the invention is shown. In this example, the angled or offset connecting portion 3.3 of the metal part engages with or overlaps with another component 5 connected to or attached to the post-attached component (e.g., a crossbeam) 1. In other words, in this case, an additional mounting space is used, located below the offset or angled connecting portion 3.3 in the form of a shoulder of an eccentric retainer. This mounting space can be used to arrange or further connect components 5, such as tie rod supports. Component 5, for example, made of steel or another metal, is preferably also welded to the post-attached component 1, whereby the weld joint (e.g., a fillet weld 6) is located below the shoulder of the eccentric retainer. The connecting portion 3.3 is angled or offset relative to the attachment portions 3.1, 3.2 of the metal part 3 to such an extent that it does not directly contact the component 5 but is spaced at a distance from it.

[0047] The connecting portion 3.3 may be at least partially offset parallel to the attachment portions 3.1 and 3.2 of the metal part 3. In this sense, the connecting portion 3.3 is disposed in a plane that extends at all points at substantially the same distance from another plane on which the attachment portions 3.1 and 3.2 of the metal part 3 are disposed (see...). Figure 1 , Figure 2 and Figure 5 ).

[0048] However, the at least partial offset of the connecting portion 3.3 relative to the attachment portions 3.1 and 3.2 at a certain angle is also within the scope of this invention. In such cases... Figure 9 In the illustrated case, the connecting portion 3.3 is, for example, at least partially disposed in a plane that extends at an angle to another plane on which the attachment portions 3.1 and 3.2 of the metal part 3'' are disposed. The two planes in question preferably extend such that they define an acute angle S between them, whereby this angle S can be in the range of approximately 5° to 25°, particularly preferably in the range of approximately 8° to 15°. The radius of curvature R'' of the bent area of ​​the metal part 3'' can more or less correspond to, as shown in the figure... Figures 1 to 3 The curvature radius R of the bending regions 3.5 and 3.6 of the metal part 3 shown.

[0049] Figures 6 to 8 Another embodiment of the invention is shown. This embodiment is related to... Figures 1 to 3 The difference in the illustrated embodiment is that the connecting portion 3.3 forms only one angle with respect to the attachment portions 3.1 and 3.2 of the metal member 3', rather than several angles. The connecting portion 3.3, angled relative to the attachment portions 3.1 and 3.2, has a substantially flat surface on its side facing away from the mounting member 1.1 of the subsequent attachment 1. This flat surface is connected to the surfaces of the attachment portions 3.1 and 3.2 facing away from the mounting member 1.1 via the curved regions 3.5' and 3.6' of the metal member 3'. In this embodiment, the connecting portion 3.3 is substantially arranged in a plane that extends obliquely relative to the plane on which the attachment portions 3.1 and 3.2 of the metal member 3 are arranged. This plane further extends such that they define an obtuse angle A between them, for example, in the range of approximately 130° to 175°, preferably in the range of approximately 140° to 160°.

[0050] exist Figures 6 to 8 In the embodiment shown, the radius of curvature R' of the bending regions 3.5' and 3.6' of the metal part 3' is significantly larger than that according to... Figures 1 to 3 The bending areas of metal part 3 are 3.5 and 3.6 (R). According to Figures 6 to 8 The radii of curvature R' of the bending regions 3.5' and 3.6' of the eccentric limiting member in the illustrated embodiment are, for example, in the range of approximately 5 mm to 12 mm, or in the range of 2.5 to 6 times the thickness D or average thickness D of the metal part 3' or the attachment portions 3.1 and 3.2, and according to Figures 1 to 3 The radii of curvature R of at least two bending regions 3.5, 3.6 of the eccentric limiting member in the illustrated embodiment are, for example, in the range of about 2 mm to 4 mm, or in the range of 0.8 to 2 times the thickness D or average thickness D of the attachment portions 3.1, 3.2.

[0051] Figure 11 The illustrated embodiments and Figure 1 The difference in the illustrated embodiment is that the connecting portion 3.3, which is angled or offset relative to the attachment portions 3.1 and 3.2, has a fastening structure 3.32, for example, in the form of a lug or eyelet, wherein the fastening structure 3.32 is preferably provided with a fastening opening 3.33, such as a fastening hole. The fastening structure 3.32 can be formed at any point on the connecting portion 3.3. Preferably, the fastening structure 3.32 or the fastening opening 3.33 is located within the center length range or arc length range of the connecting portion 3.3.

[0052] Fastening device 7 is mounted or connected to fastening structure 3.32 or fastening opening 3.33 for fastening one or more pipelines. Fastening device may be, for example, a mounting piece, clamp, expansion rivet, or rivet nut. The pipeline to be fastened to fastening device 7 may be, for example, pneumatic, hydraulic, or electrical pipeline. Figure 12 An embodiment is shown in which the fastening device 7 is designed in the form of a clamp or an expansion rivet, the fastening device having one or more clamping elements 7.1 at one end for securing one or more pipelines (not shown).

[0053] In addition, Figure 12 The description outlines that the eccentric limiting member (metal part 3''') according to the invention can also be connected to the post-addition 1 in a material-locking manner by welding other than fillet welding (e.g., by means of resistance welding, specifically projection welding).

[0054] The implementation of this invention is not limited to the embodiments shown in the accompanying drawings. Rather, numerous variations of at least one of the embodiments of the invention specified in the appended claims are contemplated, even if the design differs from the examples shown.
