Chassis component with one joint

Description

[0001] The invention relates to a chassis component with an inner joint part having the features of the preamble of claim 1.

[0002] Such a chassis component is known from DE 10 2007 028 265 A1. Other similar designs can be found in FR 2 973 292 A1 or DE 102 21 873 A1.

[0003] According to DE 10 2019 201 521 A1, it is known that the measuring device has, among other things, a pin-like sensor strut which is inserted into a blind hole-like recess in the structural part.

[0004] However, not every structural part offers the possibility of forming a blind hole-like recess for arranging a measuring element within the recess, since more massive interventions and / or machining of the structural part for receiving a measuring element can weaken the strength of the structural part in an undesirable way.

[0005] Furthermore, it is known from the prior art to arrange the measuring element assigned to the inner joint part as close as possible to the center of a kinematic point and / or a joint center point of the inner joint part. For example, a corresponding measuring element is arranged within a joint ball of an inner joint part or within a rubber material of a rubber bearing. However, this is at least partially associated with increased manufacturing effort and / or costs.

[0006] The object underlying the invention is to further develop a chassis component of the type mentioned above in such a way that an arrangement of the measuring device, the first measuring element, and / or the second measuring element can be implemented in a simplified and / or more cost-effective manner. In particular, an alternative embodiment is to be provided.

[0007] The object underlying the invention is achieved with a chassis component according to claim 1. Preferred developments of the invention can be found in the subclaims and in the following description.

[0008] Accordingly, the invention relates to a chassis component. In particular, the chassis component is arranged in the chassis of a vehicle, preferably a motor vehicle. A chassis component can generally be a chassis support, a cross member, an axle support, a flange joint, a wheel support, or a chassis control arm.

[0009] The chassis component has an inner joint part. Furthermore, the chassis component has a structural part, wherein the inner joint part is articulated in a joint receptacle of the structural part. In particular, a joint of the chassis component is formed by means of the inner joint part articulated in the joint receptacle. The joint can be designed as a ball joint, in particular a ball sleeve joint, or a ball and socket joint. Furthermore, the joint can be implemented as a rubber joint.

[0010] The chassis component has a measuring device for determining a relative position of the inner joint part in relation to the structural part. In particular, the measuring device is designed as an angle measuring device. The measuring device has a first measuring element and a second measuring element. The first measuring element is arranged on the structural part and the second measuring element on the inner joint part. The structural part can predetermine or define a contour or basic shape of the chassis component. In particular, the joint receptacle of the structural part is designed as an opening or as a through-opening in the structural part. Alternatively, the joint receptacle of the structural part can be pot-shaped and / or cup-shaped. In particular, the structural part and the inner joint part are designed to be rotatable, pivotable and / or tiltable relative to one another.The measuring device can detect a relative rotation, pivoting, and / or tilting of the structural part to the inner joint part and about at least one or more axes of rotation. In particular, the first measuring element and the second measuring element cooperate to determine the relative position between the inner joint part and the structural part. The inner joint part extends out of the joint receptacle, with the second measuring element being attached to a section of the inner joint part located outside the joint receptacle.

[0011] The advantage here is that the second measuring element is arranged neither inside the inner joint part nor inside the joint receptacle. Instead, the second measuring element is fastened to a section of the inner joint part located outside the joint receptacle. This ensures that the second measuring element moves or can be moved together with the inner joint part and in relation to the structural part. At the same time, the manufacturing effort and / or cost required to arrange the second measuring element on the inner joint part is reduced. The arrangement of the first measuring element, which interacts with the second measuring element, on the structural part can also be implemented more easily and / or more cost-effectively by arranging the second measuring element on a section of the inner joint part located outside the joint receptacle.

[0012] According to a further development, the first measuring element is attached to a surface and / or to a flat surface section of the structural part. In particular, the first measuring element is attached to the surface and / or the flat surface section adjacent to the joint mount and / or to the second measuring element. Due to the arrangement of the first measuring element on the surface and / or the flat surface section, the strength of the structural part is not, or at least not significantly, impaired. To form the flat surface section, the surface of the structural part can be machined, in particular by cutting.

[0013] The structural part preferably has a fastening receptacle for fastening the first measuring element to the surface and / or to the flat surface section. For this purpose, the fastening receptacle can cooperate with a suitably designed fastening means. Such a fastening means can be designed as a screw, a pin, or a rivet. The fastening means can be screwed, pressed, and / or cast into the fastening receptacle. The fastening receptacle can be designed as a blind hole. However, since the fastening receptacle is designed exclusively to accommodate the fastening means and not to partially or completely accommodate the first measuring element itself, the strength of the structural part is not significantly impaired.

[0014] According to a further embodiment, the first measuring element has an alignment element for directed arrangement and / or fastening to the structural part. In particular, the structural part has an alignment receptacle for receiving the alignment element. Preferably, the alignment element is positively received and / or inserted into an alignment receptacle of the structural part. The alignment element can be designed as a projection or as a nose of the first measuring element. Due to the interaction of the alignment element with the alignment receptacle, in particular in combination with the interaction of the fastening receptacle and the fastening means, a predetermined orientation of the first measuring element or a predetermined alignment of the first measuring element in relation to the structural part and / or to the second measuring element is ensured.Preferably, due to the interaction of the alignment element with the alignment receptacle, in particular in combination with the interaction of the fastening receptacle with the fastening means, an undesired rotation of the first measuring element with respect to the structural part is reliably prevented or blocked.

[0015] According to a further development, the section of the inner joint part with the second measuring element is designed as a, in particular stepped, free end of the inner joint part. The free end of the inner joint part can have a simply stepped outer contour. In particular, due to the stepped outer contour, an outer diameter of an outer stepped section of the inner joint part is smaller than an inner stepped section of the inner joint part that is axially smaller with respect to a central longitudinal axis of the inner joint part and the outer stepped section.

[0016] The second measuring element can have a ring-like holding section. Preferably, the ring-like holding section of the second measuring element is plugged and / or pressed onto the section, in particular the outer stepped section, of the inner joint part. The inner stepped section can serve as a support for the holding section. In particular, the ring-like holding section is plugged and / or pressed onto an outer circumference of the section of the inner joint part. In this way, the second measuring element can be connected to the inner joint part in a simple and cost-effective manner.

[0017] Preferably, the second measuring element, in particular the holding section of the second measuring element, and the section of the inner joint part that interacts with the second measuring element form an anti-rotation device for preventing and / or blocking a relative movement and / or rotation of the second measuring element with respect to the inner joint part, in particular about a central longitudinal axis of the inner joint part. Thus, a relative movement between the second measuring element and the inner joint part is prevented or blocked by means of the anti-rotation device. The anti-rotation device can be formed by means of at least one flattened portion on an outer circumference of the section of the inner joint part, which flattened portion interacts with a correspondingly formed further flattened portion on an inner circumference of the second measuring element, in particular the holding section of the second measuring element.In particular, the flattened portion on the outer circumference of the section of the inner joint part and the further flattened portion on the inner circumference of the second measuring element interact in a form-fitting manner. Such a form-fitting arrangement or such flattened portions can be produced simply and cost-effectively. Alternatively, the section of the inner joint part can have a polygonal or non-circular outer circumference that interacts with a correspondingly shaped polygonal or non-circular inner circumference of the second measuring element. This also allows for an effective anti-rotation device to be easily implemented.

[0018] Preferably, the first measuring element has at least one magnetic field sensor, and the second measuring element has a magnet. The magnet can be designed as a permanent magnet. The magnet generates a magnetic field, without the need for external energy supply, which is operatively connected to the magnetic field sensor of the first measuring element. In particular, the first measuring element has several, preferably three, magnetic field sensors. In particular, the several magnetic field sensors are arranged along and / or adjacent to a movement path of the magnet during normal use of the chassis component. By means of the several magnetic field sensors, the signal quality of the measuring device can be increased and / or improved. The magnetic field sensor can be designed as a Hall sensor.

[0019] The magnet is arranged at a free end of a web-like projection of the second measuring element. The magnet and / or the web-like projection is aligned such that it faces the first measuring element and / or the magnetic field sensor. Preferably, the first measuring element and the second measuring element are aligned and / or arranged relative to one another such that a distance between the magnet and the magnetic field sensor is less than 10 mm. Preferably, the web-like projection extends outwards in the radial direction from a holding section of the second measuring element beyond an outer circumference of the inner joint part. Preferably, the web-like projection and the holding section of the second measuring element are formed as a single piece.

[0020] According to a further development, the magnet is arranged and / or encapsulated within a plastic magnet holder. This allows the magnet to be protected from environmental influences, dirt, and / or stone chips. In particular, the magnet and / or the magnet holder is attached to the web-like projection by means of a detachable plug-in and / or snap-in connection. Due to the detachable plug-in and / or snap-in connection, the magnet can be easily changed or replaced as needed. To form the plug-in and / or snap-in connection, the magnet holder and the web-like projection can have positive-locking elements designed to correspond to one another, in particular at least one snap-in lug and at least one snap-in receptacle. Alternatively, the magnet holder can be manufactured and / or injection-molded directly onto the web-like projection using an injection-molding process.

[0021] According to the invention, the second measuring element, in particular a magnet of the second measuring element, is guided at least partially within a guide of the first measuring element. Thus, the first measuring element has a guide for guiding the second measuring element, in particular the magnet of the second measuring element. The guide enables rotation of the second measuring element about a central longitudinal axis of the inner joint part. At the same time, tilting of at least part of the second measuring element, in particular the magnet of the second measuring element, axially relative to the central longitudinal axis can be at least partially or completely compensated, balanced, and / or blocked by means of the guide.In other words, the guide enables rotation of the second measuring element about the central longitudinal axis of the inner joint part, while at the same time at least partially or completely compensating, balancing, and / or blocking tilting of at least the magnet of the second measuring element about a rotational axis transverse or perpendicular to the central longitudinal axis of the inner joint part. This prevents unwanted disturbances caused by tilting of the magnet about the rotational axis arranged transversely or perpendicular to the central longitudinal axis.

[0022] According to the invention, a web-like projection of the second measuring element has a first projection section and a second projection section. The first projection section and the second projection section are pivotally connected to one another by means of a hinge. The hinge can be used to compensate for a tilting movement of the second measuring element in the axial direction relative to the central longitudinal axis of the inner joint part and / or about a rotational axis arranged transversely or at right angles to the central longitudinal axis.

[0023] In particular, the inner joint part is designed as a ball sleeve, a joint sleeve, or a rubber bearing. A joint formed by combining the inner joint part with the joint receptacle of the structural part can be designed as a ball joint or a rubber joint. Preferably, the joint sleeve interacts with a rubber bearing within the joint receptacle to form a rubber joint. The design of the measuring device is considerably simplified due to the arrangement of the second measuring element on the section of the respective inner joint part located outside the joint receptacle. The chassis component can be designed as a control arm, for example, a two-point control arm.

[0024] The invention is explained in more detail below with reference to the figures. Like reference numerals refer to like, similar, or functionally identical components or elements.

[0025] Figure 1shows a section of a perspective and partially transparent side view of a first chassis component 1 not according to the invention. The chassis component 1 has an inner joint part 2 and a structural part 3. In this exemplary embodiment, the inner joint part 2 is designed as a joint sleeve made of metal. The structural part 3 determines the basic shape of the chassis component 1. The structural part 3 is inherently stable or dimensionally stable and, in this exemplary embodiment, is made of metal. Furthermore, the structural part 3 has a joint receptacle 4. The joint receptacle 4 is designed here as an opening or a through-opening in the structural part 3. The inner joint part 2 is mounted in the joint receptacle 4 in such a way that it can be moved by means of an articulated joint.

[0026] Furthermore, the chassis component 1 has a measuring device 5. The measuring device 5 is designed to determine a relative position of the inner joint part 2 with respect to the structural part 3. For this purpose, the measuring device 5 has a first measuring element 6 and a second measuring element 7. The first measuring element 6 is arranged or attached to the structural part 3, and the second measuring element 7 is arranged or attached to the inner joint part 2. The first measuring element 6 is shown partially transparent here.

[0027] The inner joint part 2 extends out of the joint receptacle 4. The second measuring element 7 is attached to a section 8 of the inner joint part 2 located outside the joint receptacle 4. Section 8 of the inner joint part 2 is designed as a simply stepped free end of the inner joint part 2. The second measuring element 7 has a ring-like holding section 9. The ring-like holding section 9 is pressed onto the stepped section 8 of the inner joint part 2 or onto an outer circumference of section 8.

[0028] Here, the holding section 9 and the section 8 of the inner joint part 2 interacting with this holding section 9 form an anti-twist device 10 for preventing or blocking a relative movement or rotation of the second measuring element 7 in relation to the inner joint part 2. In this exemplary embodiment, the anti-twist device 10 is formed by means of a flattened portion 11 on the outer circumference of the section 8 of the inner joint part 2, which flattened portion 11 interacts with a correspondingly formed further flattened portion 12 on an inner circumference of the holding section 9.

[0029] The second measuring element 7 has a web-like projection 13. The web-like projection 13 extends in the radial direction from the holding section 9 and, with respect to a central longitudinal axis of the inner joint part 2 (not shown in detail here), beyond the outer circumference of the inner joint part 2 to the outside. A magnet 14 of the second measuring element 7 is arranged at a free end of the web-like projection 13. The magnet 14 is oriented so as to face the first measuring element 6. In this exemplary embodiment, the magnet 14 is arranged on an end face of a free end of the projection 13. The end face faces the first measuring element 6. In particular, a plane of the end face is oriented parallel to the central longitudinal axis of the inner joint part 2, at least in the undeflected position of the inner joint part 2 shown here.

[0030] The magnet 14 is arranged within a magnet holder 15. The magnet holder 15 is shown partially transparent here. The magnet holder 15 is made of a plastic, with the magnet 14 being completely surrounded by the plastic of the magnet holder 15. In this exemplary embodiment, the web-like projection 13 has two holes 16. For better clarity, only a single hole 16 is provided with a reference symbol. The magnet holder 15 is injection-molded directly onto the free end of the web-like projection. The plastic material of the magnet holder 15 penetrates the holes 16, whereby the magnet holder 15 is reliably attached to the projection 13 and excludes any relative movement between the magnet holder 15 and the projection 13.

[0031] The first measuring element 6 has a magnetic field sensor 17. The magnetic field sensor 17 faces the magnet 14 of the second measuring element 7. The distance between the magnetic field sensor 17 and the magnet 14 is less than 10 mm. The first measuring element 6 is fastened to a flat surface section 18 of the structural part 3 and adjacent to the joint receptacle 4. In this exemplary embodiment, the flat surface section 18 is formed on the structural part 3 by means of machining. The first measuring element 6 is fastened to the structural part 3 by means of a fastening means 19. For cooperation with the fastening means 19, the structural part 3 has a fastening receptacle 20. In this exemplary embodiment, the fastening means 19 is designed as a screw that is screwed into the fastening receptacle 20.

[0032] Furthermore, in this embodiment, the structural part 3 has an alignment receptacle 21. The design and function of the alignment receptacle 21 are explained in more detail with reference to the following figure.

[0033] Figure 2 shows a section of a sectional side view of the first chassis component 1 not according to the invention according to Figure 1. In this embodiment, the alignment receptacle 21 is designed as a blind hole-like depression in the structural part 3. The first measuring element 6 has an alignment element 22 for the directed arrangement of the first measuring element 6 on the structural part 3. Due to the interaction of the alignment receptacle 21 with the alignment element 22 and in combination with the interaction of the fastening means 19 with the fastening receptacle 20, a clearly predetermined alignment and positioning of the first measuring element 6 on the structural part 3 and in relation to the second measuring element 7 results. The magnetic field sensor 17 and the magnet 14 are aligned to one another such that a distance A of less than 10 mm results.

[0034] In this exemplary embodiment, the inner joint part 2 is designed as a joint sleeve in combination with a rubber bearing 23. The inner joint part 2 has a central longitudinal axis 24. Concentric with the central longitudinal axis 24, the inner joint part 2 has a through-opening 25. The rubber bearing 23 is arranged between the inner joint part 2 and an outer sleeve 26. The outer sleeve 26 is made of metal in this exemplary embodiment. The inner joint part 2, together with the rubber bearing 3 and the outer sleeve 26, is pressed into the joint receptacle 4. The inner joint part 2, together with the rubber bearing 23 and the outer sleeve 26, forms a rubber joint.

[0035] The first measuring element 6 has a plug section 27 at an end facing away from the magnetic field sensor 17. A signal line and / or electrical line (not shown in detail here) can be connected to the first measuring element 6 by means of the plug section 27. This allows a measurement signal from the measuring device 5 or the first measuring element 6 to be forwarded to an evaluation device (not shown in detail here).

[0036] Figure 3 shows a section of a partially transparent plan view of the first chassis component 1 not according to the invention according to Figures 1 and 2 with the second measuring element 7 in three different positions. The second measuring element 7 is shown in a central starting position 28. In the starting position 28, which corresponds to an undeflected position of the inner joint part 2, the magnet 14 is at a minimum distance A according to Fig. 2aligned with the magnetic field sensor 17. In other words, in the starting position 28, the magnetic field sensor 17 and the magnet 14 are opposite each other.

[0037] Furthermore, the second measuring element 7 is shown in partially transparent representations in two differing end positions 29, 30. The end positions 29, 30 result from a twisting or rotation of the inner joint part 2 together with the second measuring element 7 about the central longitudinal axis 24. Due to the resulting displacement of the magnet 14, a magnetic field change occurs that can be determined by the magnetic field sensor 17. This can be used to determine the relative position of the structural part 3 with respect to the inner joint part 2.

[0038] In this embodiment, the first end position 29 results from the starting position 28 due to a rotation about the central longitudinal axis 24 by +25°. The second end position 30 results from the starting position 28 due to a rotation about the central longitudinal axis 24 by -25°. Thus, in this embodiment, an angular range of 50° results, which can be detected by the measuring device 5.

[0039] Figure 4 shows a section of a partially transparent side view of the first chassis component 1 not according to the invention according to Figures 1 and 2and with the second measuring element 7 in three further different positions. First, the second measuring element 7 is shown in a central starting position 31. Starting from the starting position 31, the inner joint part 2 can tilt about a rotation axis 34 according to the end positions 32, 33 shown here. In this case, the rotation axis 34 is aligned at right angles to the central longitudinal axis 24. Furthermore, the rotation axis 34 runs through a joint center point of the inner joint part 2.

[0040] Starting from the starting position 31, the magnet 14 of the second measuring element 7 moves into the first end position 32 due to a tilt of +6°. Due to a tilt of the inner joint part 2 around the rotation axis 34 starting from the starting position 31 by -6°, the magnet 14 moves into the second end position 33. Thus, a maximum angular range of 12° with respect to a tilt about the rotation axis 34 or the joint center is shown here. The magnetic field change generated due to the tilt can be detected by the magnetic field sensor 17.

[0041] Figure 5 shows a section of a perspective, partially transparent top view of the first measuring element 6 with the magnetic field sensor 17 and the second measuring element 7 with the magnet 14 in the sense of the first chassis component 1 not according to the invention according to Figures 1 and 2 The magnet holder 15 is shown transparent here. In contrast to the design according to the Figures 1 to 4In the variant shown here, the magnet holder 15 is not molded directly onto the free end of the web-like projection 13. Instead, the magnet holder 15 is attached to the web-like projection 13 by means of a detachable plug-in and snap-in connection 35. This allows the magnet 14 to be replaced or exchanged.

[0042] To form the plug-in and latching connection 35, the magnet holder 15 in this embodiment has form-locking elements 36. In this embodiment, the magnet holder 15 has two form-locking elements 36, although for the sake of clarity, only one form-locking element 36 is provided with a reference number here. The web-like projection 13 has form-locking elements 37 designed to correspond to the form-locking elements 36. In this embodiment, the form-locking elements 37 are designed as latching receptacles and are realized here by means of the holes 16. The form-locking elements 36 of the magnet holder 16 are realized here as latching lugs that engage or snap into the holes 16 in a form-fitting manner.

[0043] For chassis component 1 according to Figures 1 to 5The magnetic field sensor 17 is oriented perpendicular to the longitudinal extent of the structural part 3. Accordingly, the magnet 14 is also oriented perpendicular to the longitudinal extent of the structural part 3 or to a plane of the holding section 9, corresponding to the magnetic field sensor 17, or is arranged within the magnet holder 15.

[0044] Figure 6 show a section of a perspective and partially transparent side view of a second chassis component 38 not according to the invention. The same features as before bear the same reference numerals. To avoid repetition, reference is also made to the preceding description.

[0045] In contrast to the chassis component 1, in the chassis component 38 shown here, the magnet 14 is not arranged on a front side of the free end of the projection 13. Instead, the magnet 14 is arranged in the region of a side 39 of the web-like projection 13, with the side 39 facing the structural part 3. The magnetic field sensor 17 is arranged between the magnet 14 and the structural part 3.

[0046] Compared to the chassis component 1, the chassis component 38 shown here has a somewhat flatter and thus more space-saving design due to the arrangement and orientation of the magnet 14 and the magnetic field sensor 17.

[0047] Figure 7 shows a section of a sectional side view of the second chassis component 38 not according to the invention according to Figure 6Identical features as previously mentioned bear the same reference numerals. To avoid repetition, reference is also made to the previous description.

[0048] While the distance A for the chassis component 1 is according to the Figures 1 to 5 extends at right angles to the central longitudinal axis 24, the distance A in the chassis component 38 shown here extends in the axial direction or parallel to the central longitudinal axis 24.

[0049] Figure 8 shows a section of a partially transparent top view of the second chassis component 38 not according to the invention according to Figures 6 and 7 with the second measuring element 7 in three different positions. Identical features carry the same reference numerals as before. To avoid repetition, particular reference is made to the previous Figure 2 whose description is transferable here accordingly.

[0050] Figure 9shows a section of a partially transparent side view of the second chassis component 38 not according to the invention according to Figures 6 and 7 with the second measuring element 7 in three further different positions. The same features bear the same reference numerals as before. To avoid repetition, particular reference is made to the previous Figure 4 whose description is transferable here accordingly.

[0051] Figure 10 shows a section of a perspective and partially transparent side view of a further chassis component 40 according to the invention. The same features as before bear the same reference numerals. To avoid repetition, reference is also made to the previous description.

[0052] In this exemplary embodiment, the chassis component 40 does not have an anti-twist device 10. Instead, the holding section 9 of the second measuring element 7 according to this exemplary embodiment has a plurality of holding elements 41 on its inner circumference. In this exemplary embodiment, a total of four holding elements 41 are arranged evenly distributed on the inner circumference of the ring-like holding section 9. The holding elements 41 are designed, for example, as fixing lugs and are formed integrally with the holding section 9. By means of the holding elements 41, the second measuring element 7 is pressed onto the outer circumference of the section 8 of the inner joint part 2 and is simultaneously held thereon in a rotationally fixed manner with respect to the inner joint part 2. In this exemplary embodiment, in contrast to the variants according to Figures 1 to 9 a directed pressing in of the joint formed by the inner joint part, the rubber bearing 23 and the outer sleeve 26 can be dispensed with.

[0053] In this embodiment, the first measuring element 6 has a guide 42. In this embodiment, the guide 42 is formed by two curved legs 43, 44 spaced apart from one another in the axial direction relative to the central longitudinal axis of the inner joint part 2. The guide 42 is formed at an end of the first measuring element 6 facing the second measuring element 7. The magnet 14 of the second measuring element 7 is guided within the guide 42. The magnet 14 is thus guided between the two legs 43, 44.

[0054] In this embodiment, the web-like projection 13 is formed from a first projection portion 45 and a second projection portion 46. The two projection portions 45, 46 are pivotally connected to one another by means of a hinge 47. According to this embodiment, the second connecting portion 46 simultaneously forms the magnet holder 15, with the magnet 14 being arranged in the region of a free end of the second projection portion 46 facing away from the hinge 47.

[0055] Figure 11 shows a section of a sectional side view of the further chassis component 40 according to the invention according to Figure 10 Identical features as previously mentioned bear the same reference numerals. To avoid repetition, reference is also made to the previous description.

[0056] The magnetic field sensor 17 of the first measuring element 6 is arranged within the leg 43 of the guide 42. The guide 42 enables rotation of the second measuring element 7 or the magnet 14 about the central longitudinal axis 24 of the inner joint part 2. At the same time, the guide 42 prevents or reduces tilting of the magnet 14 in a direction axial to the central longitudinal axis 24. In this case, a tilting movement of the inner joint part 2 about the rotation axis 34, which is oriented perpendicular to the central longitudinal axis 24, is compensated by the hinge 47. For this purpose, a pivot axis of the hinge 47 is aligned parallel to the rotation axis 34.

[0057] Figure 12 shows a section of a partially transparent top view of the further chassis component 40 according to the invention according to Figures 10 and 11with the second measuring element 7 in three different positions. Identical features carry the same reference numerals as before. To avoid repetition, particular reference is made to the previous description of the Figures 3 and 8 referred to.

[0058] In this exemplary embodiment, the first measuring element 6 has a single magnetic field sensor 17. Alternatively, the first measuring element 6 can have several, in particular three, magnetic field sensors 17. For example, as already illustrated here, a single magnetic field sensor 17 can be arranged centrally within the guide 42 of the first measuring element 6. In this case, the distance between the central magnetic field sensor 17 and the magnet 14 is smallest in the starting position 28 illustrated here.

[0059] In addition, the first measuring element 6 can have two further magnetic field sensors 17 (not shown in detail here). In this case, a second magnetic field sensor 17 can be arranged on the first measuring element 6 and within the guide 42 such that the distance between the second magnetic field sensor 17 and the magnet 14 is smallest in the first end position 29 shown here. A third magnetic field sensor 17 (not shown in detail here) can be arranged on the first measuring element 6 and within the guide 42 such that the distance between the third magnetic field sensor 17 and the magnet 14 is smallest in the second end position 30 shown here.

[0060] Figure 13 shows a section of a partially transparent side view of the further chassis component 40 according to the invention according to Figures 10 and 11with the second measuring element 7 in three further different positions. The same features bear the same reference numerals as before. To avoid repetition, reference is made to the previous description, in particular Figures 4 and 9 referred to.

[0061] When the inner joint part 2 tilts about the rotation axis 34, the holding section 9 and the first projection section 45 also tilt. However, due to the hinge 47 and the guidance of the second projection section 46 or the magnet holder 15 within the guide 42, a displacement of the magnet 14 in a direction axial to the central longitudinal axis 24 is prevented or at least partially compensated or balanced.
