Description
The invention relates to a device for storing at least one component in a vehicle and to a vehicle or vehicle element comprising this device. In vehicles, components can be mounted to a vehicle or vehicle part using bearing supports. If these components can cause vibrations during operation, whether due to external forces or their own operation, the bearing supports are attached to the vehicle in such a way that the components are vibrationally decoupled from the vehicle. Effective decoupling of high-frequency vibrations is achieved by using low-damping elements. A bearing device is known from DE 10 2017 126 156 B3, which is designed for vibration-resistant mounting and decouples vibrations between a component and a vehicle element. A coil spring is arranged between the component and the vehicle element, decoupling vibrations between the component and the vehicle. The component rests on the coil spring against the vehicle. The coil spring is connected to the vehicle and transmits loads via a sliding element designed as a sleeve to an elastomer element that is connected to the component. Typically, the coil spring is made of steel. From DE 10 2016 001 507 A1, a vibration damper with radially acting hydraulic damping is known. The vibration damper comprises a bearing core, a bearing cage radially surrounding the bearing core, an elastomer body resiliently connecting the bearing core and the bearing cage, and an outer sleeve radially surrounding the elastomer body for connection with a damping mass, wherein at least two working chambers to be filled with a damping fluid are formed in the elastomer body, the working chambers being fluidically connected to each other via a dimensionally stable fluid channel. From DE 10 2015 116 799 A1 a rubber solid bearing for arrangement on a motor vehicle axle, comprising an inner sleeve and an outer sleeve, wherein an elastic intermediate layer is arranged between the inner sleeve and the outer sleeve and the inner sleeve has a stop disc on one side which extends radially outwards from the inner sleeve, wherein the outer sleeve extends in axial direction A over a part of the inner sleeve and a gap is formed between the outer sleeve and the stop disc, wherein at least one intermediate piece made of solid material is arranged in the area of the gap. Matching the radial to axial stiffness of steel springs can be challenging, and low-damping steel springs tend to develop eigenmodes under high-frequency excitation, generating stiffness peaks. Therefore, there is a need to simplify the decoupling process. When using elastomer springs instead of steel springs, an additional sleeve is usually required for the safe transmission of loads. The connection between the elastomer spring and the additional spring is generally achieved through a material bond. However, this requires a complex manufacturing process. The object of the invention is therefore to provide a device for storing at least one component in a vehicle that is easy to manufacture and cost-effective. The main features of the invention are specified in claims 1 and 16. Embodiments are the subject of claims 2 to 15 and 17. In a first aspect of the invention, a device for storing at least one component in a vehicle is provided, comprising: at least one support element for supporting the device on the vehicle or a vehicle element, wherein the support element has a first end piece and a second end piece opposite the first end piece along a longitudinal axis of the support element, the support element having a retaining element on the second end piece for connecting to a damping element; at least one bearing receptacle for receiving the component, which has a connection area for connecting to a stop element and is spaced apart from the support element in a radial direction with respect to the longitudinal axis; at least one stop element arranged in the radial direction between the bearing receptacle and the support element, which is attached to the connection area and comprises a stop surface facing the support element;and at least one damping element for damping vibrations, which is attached to the stop element and the holding part; wherein the stop element is movably mounted relative to the support part in the radial direction and an axial direction with respect to the longitudinal axis by means of the damping element. According to the invention, a device for mounting at least one component in a vehicle is provided, in which the damping element merely decouples the component from the vehicle, and the stop element establishes the connection between the mounting and the damping element. The functions of damping and the secure connection of the damping element to the mounting are thus divided between two different elements. The damping element is connected to a support element that supports the device against a vehicle or vehicle component. A first end of the support element is connected to the vehicle or vehicle component, and a second end of the support element, opposite the first end, is connected to the damping element. The damping element is connected via a stop element to a mounting for receiving the component.The stop element is mounted to the support part by means of the damping element, allowing movement in both a radial and an axial direction with respect to a longitudinal axis of the support part that extends between the first and second end pieces. This means that the stop element, with its bearing receptacle, can oscillate axially and radially with respect to its longitudinal axis. In the radial direction, the stop element is positioned between the bearing receptacle and the support part and comprises a stop surface facing the support part. Therefore, when the component, with its bearing receptacle and stop element, contacts the support part in the radial direction during an oscillation, the stop surface of the stop element strikes the support part. The forces generated by this impact are absorbed by the stop element.Preferably, the damping element has a low stiffness, so that high-frequency vibrations of the component, particularly in the axial direction, are completely or almost completely damped by the damping element. This provides a device for mounting at least one component in a vehicle that is easy to manufacture and cost-effective. The stop element thus creates a stop in every radial direction to the longitudinal axis between the support part and the bearing housing. The stop element has sufficient play to initially move radially without impact on the support part. This protects the bearing housing and the damping element from damage caused by strong vibrations or shocks. For example, the damping element can be designed as an elastomer molded part. Elastomer molded parts are easy and inexpensive to manufacture. Furthermore, adjusting the axial and radial stiffness of elastomer molded parts is significantly easier than with steel springs. In particular, axial vibrations can be almost completely dampened by elastomer molded parts with low axial stiffness. According to the invention, the connection area has a wall element, wherein the damping element is at least partially clamped between the stop element and the wall element. By positioning the damping element between the wall element and the stop element, secure mounting of the damping element to the device can be achieved. This also provides overload protection. In particular, because the damping element is clamped between the wall element and the stop element, reliable operation is ensured. The stop element thus not only connects the damping element to the bearing housing, but also secures the damping element to the bearing housing. For example, the wall element can extend parallel to the longitudinal axis, be conical, or be arranged in a similar manner relative to the longitudinal axis. Furthermore, the wall element can extend, for example, around its longitudinal axis. The wall element can thus be ring-shaped and extend around the stop element and the damping element arranged between the stop element and the wall element. According to another example, it is conceivable that the stop element can be arranged between the holding part and the first end piece, with the damping element extending away from the stop element on the holding part and then at least partially in an arc towards the stop element. The damping element can thus, for example, have one or more bands or be manufactured as a tubular section, with part of each band bent over or part of the tubular section folded inwards. One end of the tubular section is then attached to the support part, the other to the stop element. The stop element can thus be suspended from the damping element and attached to the support part. In this way, the damping element can particularly effectively absorb axial and radial vibrations of the stop element or the bearing housing attached to it. Furthermore, the stop element can, for example, have a first through-opening through which the support part extends and on which the stop surface is arranged. The stop element extends around the longitudinal axis and thus also around the support part. The stop element can therefore, for example, be ring-shaped. Simultaneously, the bearing housing can also extend around the longitudinal axis and the support part. The same applies to the damping element. This results in a simple design for the device. The damping element can, for example, have a second through-opening, wherein the second through-opening is arranged to overlap the first through-opening at least partially, and the support part extends through the first through-opening and the second through-opening. The overlap of the first and second openings allows the support element to pass through both openings. The support element is then attached to the second opening, creating a connection between the stop element and the support element via the damping element between the first and second openings. According to another example, the stop surface can have at least one rib element that is directed radially towards the support part. Furthermore, the stop element can have a multitude of rib elements that can form a crown contour on the stop element. The use of at least one rib element reduces noise generation during impact. Additionally, a point-contact stop is provided on the stop surface. The point of impact of the support element on the stop surface can thus be controlled and predefined by the at least one rib element, at least at the position of the rib element. According to another example, the rib element can have a first flattened end region and a second flattened end region and extend parallel to the longitudinal axis between the first flattened end region and the second flattened end region. The rib element is thus designed with a bulbous shape. At the two flattened end sections, the rib element projects less towards the support part than between the two flattened end sections. This creates additional clearance at the end sections, which, in the event of a wobbling movement of the damping element or the stop element of the bearing housing, reduces the number of stops of the stop element on the support part. Furthermore, the rib element can extend at least partially in the direction of the longitudinal axis. In another example, at least one rib element can be arranged transversely to the longitudinal axis. In this case, the rib element can extend around the longitudinal axis and be ring-shaped. The support element can, for example, be designed as a sleeve that extends along the longitudinal axis and through which a fastening element for connecting to the vehicle or vehicle component can be passed. The fastening element can, for example, be designed as a screw that can be screwed into the vehicle or vehicle component. The support part is then attached to the vehicle or vehicle component by the fastening element. In another example, the sleeve can have an internal thread through which a screw is inserted from the underside as a fastening element. In this example, the vehicle or vehicle component has only one through-opening through which the fastening element is inserted to connect to the support on the other side. The connection is made by screwing the fastening element into the support. According to another example, the support part can be designed as a bolt that can be connected to the vehicle or vehicle element. In this example, the support part can have a thread at one end that is inserted through a suitable opening on the vehicle or vehicle element and can be screwed in place using a nut. Alternatively or additionally, in this example the support part can be screwed directly into an opening with an internal thread of the vehicle or vehicle element. Furthermore, it is conceivable that the damping element can be connected to the holding part in a form-fit, force-fit and / or material-fit manner. The damping element can preferably be permanently connected to the support part. In a positive-locking connection, the damping element can, for example, have a groove that fits over a flange of the support part. In a material-locking connection, the damping element can, for example, be connected to the support part by bonding or vulcanization. A force-locking connection can, for example, be created by clamping between the support part and the damping element. It is also conceivable that the retaining part and / or the damping element may have at least one positive locking opening to create a positive locking connection between the retaining part and the damping element. For example, if the damping element has a positive-locking opening, a pin of the retaining part can be inserted into this opening, thus creating a positive lock perpendicular to the opening. This ensures a simple and secure mounting of the damping element to the retaining part. According to another example, the holding part can be designed as a disc and the support part as a bushing and / or sleeve. The damping element can first be connected to the disc and then to the sleeve or bushing of the support part. Furthermore, in this example, the support part can have a bushing or sleeve on the vehicle or vehicle component. The disc of the retaining element then only needs to be connected to the bushing or sleeve to secure it to the vehicle. This also simplifies the installation. Furthermore, the holding part can be integrated into the support part. In this example, the retaining part can be designed as a flange on the support part. The support part may further have an elastomer layer that is arranged between the support part and the stop element. In this way, a smooth transition can be achieved between the stop element and the support part, which further reduces noise and dampens the impact of the stop element. In another aspect, the invention relates to a vehicle or vehicle element comprising a device according to the preceding description, wherein the support part is arranged with the first end piece on the vehicle or vehicle element. The advantages, effects, and further developments of the vehicle or vehicle component result from the advantages, effects, and further developments of the device described above. Therefore, reference is made to the preceding description in this regard. The support element can be formed on the vehicle or vehicle component. Further features, details and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Figures 1a-g show a schematic sectional view of the components of the device; and Figures 2a-e show schematic sectional views of various examples of the device. In the following, the device for storing a vehicle component will be designated by the reference number 10. According to Figs. 1a to 1g, the device 10 comprises a support part 12, a damping element 32, a stop element 28 and a bearing receptacle 24. In Fig. 1a, the support part 12 and the damping element 32 are shown. The support element 12 comprises a first end piece 16 and a second end piece 18, which is opposite the first end piece 16. Furthermore, the support element 12 is designed as a sleeve. The support element 12 extends along a longitudinal axis 20. An opening of the sleeve 20 also extends along the longitudinal axis 20. A retaining part 22, designed as a flange, is arranged on the second end piece 18. The damping element 32 is designed as an elastomer molded part. It has a through-opening 38 that also extends around the longitudinal axis 20 when the damping element 32 is connected to the support part 12. The damping element 32 further comprises a groove that extends along the edge of the through-opening 38. The groove is designed to receive the flange of the retaining part 22. Furthermore, the damping element 32 has a shape whose cross-section forms a U-shaped arc. The through-opening 38 of the damping element 32 is arranged on one leg 37 of the U-shaped arc, while the other leg 39 of the U-shaped arc of the damping element 32 is designed for connection with the stop element 28. In Fig. 1a, the damping element 32 and the support part 12 are shown in a separate state. In Fig. 1b, the damping element 32 is connected to the support part 12. The through-opening 38 is attached to the retaining part 22 via the groove. A positive-locking connection is created. In Fig. 1c, in addition to the connected component from Fig. 1b, the stop element 28 is shown. In this example, the stop element 28 is ring-shaped around the longitudinal axis 20 when the stop element 28 is connected to the damping element 32. The stop element 28 comprises a through-opening 36. Hereinafter, the through-opening 36 is referred to as the first through-opening and the through-opening 38 as the second through-opening. A stop surface 30 is arranged at the first through-opening 36, which delimits the stop element 28 from the first through-opening 36. At least one rib element 40 is arranged on the stop surface 30, extending radially into the first through-opening 36 with respect to the longitudinal axis 20. In this example, the stop element 28 comprises a plurality of rib elements 40. The plurality of rib elements 40 forms a crown shape on the stop element 28. In this example, the rib elements 40 all extend parallel to the longitudinal axis 20. At least one rib element 40 has a first flattened end region 42 and a second flattened end region 44, between which the rib element 40 extends. The flattening is to be understood in a radial direction, such that the rib element 40 projects deeper into the first through-opening 38 between the two flattened end regions 42, 44 than at the two flattened end regions 42, 44. In an alternative example not shown, the rib elements 40 can extend around the longitudinal axis. The stop element 28 further comprises a flange 29, which is designed as a spring for a groove arranged on the leg 39 of the damping element 32. The damping element 32 can be connected to the flange 29 of the stop element 28 via the groove on the leg 39. This is shown in Fig. 1d. The connection between the stop element 28 and the damping element 32 can be made alternatively or additionally to this form-fitting connection, by material bonding or force bonding. In addition to the connected components from Fig. 1d, Fig. 1e shows a part of the bearing receptacle 24. The bearing receptacle 24 includes a connection area 26 which has an opening 27 into which the assembled components from Fig. 1d can be inserted. In particular, the stop element 28 can be inserted into the connection area 26. The connection area 26 further includes a wall element 34 that extends around the opening 27. Alternatively or additionally, the wall element 34 can also extend only partially around the opening 27. The stop element further comprises a groove 29, which is designed to receive an edge of the opening 27. In this way, a positive-locking connection can be established between the stop element 28 and the connection area 26. This is shown in Fig. 1f. The damping element 32 is arranged between the stop element 28 and the wall element 34. The stop element 38 presses the leg 39 of the damping element 32 against the wall element 34. In this way, a secure connection between the damping element 32 and the bearing receptacle 24 can be achieved via the stop element 38. The stop element 28 is thus suspended from the support part 12 via the leg 39 of the damping element 32. The stop element 28 can oscillate axially parallel to the longitudinal axis 20 and radially. In the radial direction, the possible movement of the stop element 28, and thus of the bearing receptacle 24, is defined by the distance between the rib elements 40 and the support part 12. During a radial movement that bridges this distance, the rib elements 40 strike the support part 12. The stop element 28 absorbs the resulting force, preventing damage to the damping element 32, which is made of a soft material. To dampen the impact of the rib elements 40 on the support part 12, the support part 12 can have an elastomer layer 58. In the axial direction, the upward movement of the stop element 28 is limited by the damping element 32 itself or the support part 12. The downward movement of the stop element 28 is limited by the vehicle or vehicle element 14 when the device 10 is connected to the vehicle or vehicle element 14. This is shown in Fig. 1g. The composite component from Fig. 1f is attached to a vehicle part 14 in Fig. 1g by means of a fastening element 46. The fastening element 46 is shown here as a screw that passes through the sleeve of the support part 12 and is screwed into a threaded piece 15 of the vehicle or vehicle part 14. Figure 2a shows another embodiment of the support part 12. The support part 12 comprises a sleeve 56 and a disc 54, which are formed separately from each other. The disc 54 is initially connected to the damping element 32 as a retaining part 22. This facilitates the mounting of the disc 54 to the damping element 32. In this example, it is pressed against the sleeve 56 by the fastening element 46, which is further pressed against the vehicle part 14 by the fastening element 46. Figure 2b shows another example of the support element 12. Here, the support element 12 is designed as a bolt 50 with an external thread that can be inserted through an opening in the vehicle part 14. The bolt 50 is fastened by means of a nut 60, which is screwed onto the external thread. Fig. 2c shows another example of the support part 12. In this example, the support part 12 is equipped with a through-opening, as in the embodiment according to Figs. 1a to 1g. An internal thread is arranged at the through-opening. In this example, the fastening element 46 extends from the side of the vehicle part 14 opposite the device 10 to the side on which the device 10 is arranged. Another example of the support element 12 is shown in Fig. 2d. In this figure, the support element 12 is not yet connected to the vehicle element 14. The support element 12 has at least one positive-locking opening 48 on the retaining element 22, into which a component of the damping element 32 engages to create a positive-locking connection. In Fig. 2e, the support element 12 is designed with a disc 54, as in the example shown in Fig. 2a. The sleeve 56 from Fig. 2a is formed on the vehicle element 14 and is fixedly connected to it. The device 10 is assembled by first connecting the disc 54 to the damping element 32, the stop element 28, and the bearing receptacle 24. The disc is then placed onto the sleeve 56, which is fixedly connected to the vehicle element 14, and can then be connected to the sleeve 46 by means of a fastening element or in another way, for example, by a material-fit connection. The invention is not limited to one of the embodiments described above, but can be modified in a variety of ways. All features and advantages arising from the claims, the description, and the drawings, including design details, spatial arrangements, and process steps, can be essential to the invention both individually and in various combinations.
