BRIEF DESCRIPTION OF THE DRAWINGS
[0020] The present invention is explained in more detail below with reference to the accompanying drawings. Here, the same reference numerals represent the same, similar or functionally equivalent components or elements. Among them:
[0021] Figure 1 shows a partially transparent top view of a first chassis component according to the invention;
[0022] Figure 2 shows the method for forming the Figure 1 a perspective side view of a reinforcement at a connecting element of a first chassis component; and
[0023] Figure 3 A partially transparent top view of another chassis component according to the invention is shown. DETAILED DESCRIPTION
[0024] Figure 1A partially transparent top view of a first chassis component 1 according to the invention is shown. In this exemplary embodiment, the chassis component 1 is designed as a pivot bearing, wherein only the first end of the chassis component 1 is visible here. The chassis component 1 has a joint housing 2. The joint housing 2 is formed from a plastic material. In addition, the chassis component 1 has a connecting element 3. In this exemplary embodiment, the connecting element 3 is designed as a rod and has a longitudinal axis 4. Here, the connecting element 3 is formed, for example, from metal.
[0025] The connecting element 3 has an end section 5, wherein the end section 5 engages in a blind hole-shaped recess 6 of the joint housing 2. The end section 5 of the connecting element 3 has outer engagement contours 7, 8. The outer first engagement contour 7 is configured as an annular protrusion or recess in this embodiment, while the outer second engagement contour 8 is implemented as a protrusion or recess extending in the longitudinal direction of the longitudinal axis 4 in this embodiment. The recess 6 has inner engagement contours 9, 10 configured in a shape corresponding to the outer engagement contours 7, 8. As a result, a form-fitting connection is formed between the joint housing 2, more precisely the recess 6 and the connecting element 3, more precisely the end section 5. This form-fitting connection not only ensures that the joint housing 2 resists axial movement in the longitudinal direction of the longitudinal axis 4, but also ensures that the joint housing 2 resists rotation around the longitudinal axis 4.
[0026] The joint housing 2 furthermore has a joint receptacle 11 designed as a recess. In this exemplary embodiment, the joint receptacle 11 is designed in the region of the joint housing 2 facing away from the recess 6. Furthermore, the joint receptacle 11 is implemented as a spherical recess. The joint receptacle 11 is used to accommodate a joint ball of a ball stud, which is not shown in detail here, in an articulated manner. The joint receptacle 11 designed as a recess here extends into the joint housing 2 transversely to the longitudinal extension of the longitudinal axis 4 or at right angles to the longitudinal extension of the longitudinal axis 4.
[0027] Furthermore, the chassis component 1 has a reinforcement 12. The reinforcement 12 is arranged in the joint housing 2. The reinforcement 12 has a retaining section 13, wherein the retaining section 13 is connected to the end section 5 of the connecting element 3. The reinforcement 12 is completely embedded in the material of the joint housing 2. Therefore, the reinforcement 12 is surrounded by the material of the joint housing 2.
[0028] According to this embodiment, the reinforcement element has a first leg 14 and a second leg 15. The two legs 14, 15 are oriented parallel to each other. Furthermore, the first leg 14 extends from a first side of the end section 5 of the connecting element 3 in the direction of the joint receptacle 11. The second leg 15 also extends from a second side of the end section 5 of the connecting element 3 in the direction of the joint receptacle 11. Here, the two sides of the end section face away from each other. Therefore, the end section 5 is located between the two legs 14, 15.
[0029] Furthermore, the reinforcement element 12 has an annular section 16 in this exemplary embodiment. The annular section 16 connects the two legs 14, 15 to one another. Here, the annular section 16 extends around the joint receptacle 11. In other words, the annular section 16 surrounds or encloses the joint receptacle 11.
[0030] In this embodiment, the reinforcement 12 has a first retaining piece 17 and a second retaining piece 18 to form the retaining section 13. The two retaining pieces 17, 18 are basically L-shaped. Here, the free ends of the two retaining pieces 17, 18 face each other. The first retaining piece 17 is engaged in an outer engaging contour 7 in the outer engaging contour of the end section 5 on the first side of the end section 5. The second retaining piece 18 is engaged in the outer engaging contour 7 of the end section 5 on the second side of the end section 5 facing away from the first side. Therefore, the end section 5 is arranged between the two retaining pieces 17, 18, wherein the two retaining pieces 17, 18 interact with an outer engaging contour 7 in the outer engaging contour in a form-fitting manner. This causes a predetermined relative positioning of the reinforcement 12 relative to the connecting element 3.
[0031] Figure 2 shows the method for forming the Figure 1 A perspective side view of a reinforcement 12 at the connecting element 3 of the first chassis part 1. In this embodiment, the reinforcement 12 has a plurality of penetrations 19. For the sake of greater clarity, not all penetrations 19 are provided with reference numerals. Here, the penetrations 19 are implemented as holes. Figure 1 In the chassis component 1 of FIG. 1 , the penetration 19 is completely filled with the material of the joint housing 2 . This improves the positive connection between the material of the joint housing 2 and the reinforcement element 12 .
[0032] Here, for example, a plurality of penetrations 19 are arranged or oriented in a first row 20 and a second row 21. The two rows 20, 21 of penetrations 19 extend within the first leg 14, the annular section 16 and the second leg 15. Furthermore, in this exemplary embodiment, the penetrations 19 of the first row 20 are arranged or configured offset relative to the penetrations 19 of the second row 21.
[0033] Figure 3 A partially transparent top view of another chassis component 22 according to the invention is shown. Identical features have the same reference numerals as before. In this respect, reference is also made to the previous description in order to avoid repetitions. The chassis component 22 has a reinforcement 23. The reinforcement 23 corresponds substantially to the chassis component according to Figure 1 The reinforcement element 12 is also completely embedded in the material of the joint housing 2. The reinforcement element 23 also has a first leg 14, a second leg 15 and an annular section 16 which connects the two legs 14, 15 to one another.
[0034] According to Figure 1Compared to the reinforcement element 12 of FIG. 1 , the reinforcement element 23 shown here has a retaining section 13 without retaining tabs 17, 18. Therefore, in this exemplary embodiment, the retaining section 13 is not directly connected to the end section 5 of the connecting element 3. Instead, the retaining section 13 shown here is connected to the end section 5 via a connecting section 24 of the joint housing 2. The connecting section 24 is therefore a one-piece component of the joint housing 2 and is produced together with the joint housing 2 during the injection molding of the joint housing 2.
