Description

[0001] The invention relates to an elastomer bearing for a motor vehicle according to the preamble of the sole patent claim 1.

[0002] An elastomer bearing for a motor vehicle is already well known in the general state of the art. Such an elastomer bearing has at least one first fastening region, via which the elastomer bearing is to be held or is held on a first component of the motor vehicle, and at least one second fastening region, which is different from the first fastening region and preferably spaced apart from the first fastening region, via which the elastomer bearing is to be held or is held on a second component of the motor vehicle that is different from the first component.

[0003] Furthermore, DE 199 22 583 A1 discloses a friction-stressed plastic component, in particular an elastomer component, which contains microcapsules which release at least one tribologically active ingredient when damaged.

[0004] Furthermore, DE 101 06 383 A1 discloses a method for applying a label to a substrate.

[0005] DE 102 31 311 A1 discloses a rubber mount and its manufacturing method. The rubber mount in question preferably serves to accommodate a stabilizer or a comparable rod, tube, or the like. It has a rubber body enclosing the rod and a bushing for receiving the rubber body and the rod held therein. The rubber body and / or the rod are coated with an adhesive. According to the invention, the adhesive is microencapsulated.

[0006] DE 43 34 316 A1 discloses a vibration damper for a shaft rotating about an axis, comprising an inertia ring which is fixed in the shaft in a relatively rotatable manner by at least one spring ring made of rubber, and in that the spring ring directly contacts the outer circumference of the shaft and is pressed non-rotatably against the shaft by the inertia ring.

[0007] The object of the present invention is to provide an elastomer bearing for a motor vehicle, so that the elastomer bearing can be mounted on at least one component of the motor vehicle with particularly little effort.

[0008] This object is achieved according to the invention by an elastomer bearing for a motor vehicle having the features of patent claim 1.

[0009] In order to create an elastomer bearing of the type specified in the preamble of patent claim 1, so that the elastomer bearing can be mounted on at least one component, in particular on the first and / or second component, with particularly little effort, it is provided that, in particular for fastening the elastomer bearing to at least one of the components, at least one adhesive embedded by means of microencapsulation in at least one enveloping material, in particular formed separately from the first and / or second fastening region, is arranged at least on the first of the fastening regions, in particular directly. In other words, at least one microencapsulated adhesive is arranged, in particular directly, at least on the first of the fastening regions.This means that at least in the first of the fastening regions the microencapsulation or the enveloping material is arranged, in which the adhesive is embedded, in particular enclosed or integrated.

[0010] In particular, in a method for producing the elastomer bearing, the adhesive embedded in the casing material by means of microencapsulation can be arranged at least at the first of the fastening areas. This means that the microencapsulated adhesive can be applied at least at the first of the fastening areas.

[0011] The adhesive is formed separately from the shell material. The shell material can in particular be understood to mean a shell component. Microencapsulation can in particular be understood to mean a technique by means of which solid, liquid or gaseous substances are surrounded in tiny portions by a shell or the shell material and are thereby immobilized. Microencapsulation can therefore in particular be understood to mean inclusion immobilization. The adhesive is therefore enclosed, for example in tiny portions, in the shell material or within the shell material and is thereby in particular immobilized. In particular, the adhesive is isolated from air, in particular ambient air, by the microencapsulation or by the shell material. This means that the adhesive cannot react with the air.This means that the adhesive is prevented from reacting with the air, particularly to prevent the adhesive from sticking. Thus, the adhesive is encapsulated or insulated by the casing material, for example, in an airtight manner from the surroundings of the casing material.

[0012] For example, the wrapping material defines at least one receiving space in which at least a portion of the adhesive is arranged. For example, the wrapping material can define or form a plurality of receiving spaces in which the adhesive is arranged. Thus, the adhesive is, for example, completely surrounded by the wrapping material.

[0013] The invention is based in particular on the following findings and considerations: In a conventional elastomer bearing, it can usually be provided that a bearing seat of the elastomer bearing is designed equally for assembly and for a secure fit during operation of the elastomer bearing. This can represent a conflict of objectives, particularly under particularly high operating forces. Furthermore, the application of adhesive to the elastomer bearing, particularly to the respective fastening area, in particular using industrially automated methods, can be particularly complex, particularly costly and / or particularly demanding to clean. Furthermore, this application process may not be stable.

[0014] In contrast, the elastomer bearing according to the invention can be mounted on at least one component of the motor vehicle, in particular on the first and / or the second component, with particularly little effort. In particular, by means of the elastomer bearing according to the invention, the adhesive can be applied by means of the microencapsulation already before the elastomer bearing is mounted in the motor vehicle, at least to the first of the fastening areas. In particular, by isolating the adhesive from the ambient air, the adhesive effect of the adhesive can be prevented, whereby the elastomer bearing comprising the adhesive in the form of the microencapsulation can be transported with particularly little effort. This means that the transportability of the elastomer bearing can be ensured or particularly improved.As a result, for example, a location at which the adhesive is applied to the elastomer bearing and an assembly location at which the elastomer bearing is installed in the motor vehicle, i.e., for example, the elastomer bearing is arranged on at least one of the components, can be different from one another. In particular, the adhesive is already present on the elastomer bearing when the elastomer bearing is brought to the assembly location. This allows the elastomer bearing to be mounted on the first and / or second component with particularly little effort. In particular, the assembly location can be kept free of the adhesive or of contamination caused by the adhesive. This allows assembly to be carried out with particularly little effort.

[0015] At the assembly location, specifically designated as the target location, the elastomer bearing can be pressed into the first and / or second component, for example in a conventional manner. The adhesive embedded in the casing material can be broken up by the pressure applied to the bearing seat during the pressing process and can thus harden in the bearing seat. In particular, the aforementioned conflict of objectives regarding assembly capability and secure seating, particularly without slipping, during operation of the elastomer bearing can be resolved by means of the elastomer bearing according to the invention. Furthermore, the elastomer bearing according to the invention can be used for highly automated industrial assembly processes. Overall, it can be seen that the quality, process capability, and / or cleanliness in assembly or production can be particularly improved by means of the elastomer bearing according to the invention.

[0016] Further advantages, features, and details of the invention will become apparent from the following description of preferred embodiments and from the drawings. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the single figure, can be used not only in the respective combinations specified, but also in other combinations or on their own, without departing from the scope of the invention.

[0017] The drawing shows in the only figure a schematic partial sectional view of an arrangement of an elastomer bearing according to the invention on a first and a second component of a motor vehicle.

[0018] The sole figure shows, in a schematic front view, an arrangement of an elastomer bearing 10 for a motor vehicle on a first component 12 and on a second component 14 of the motor vehicle, which is in particular formed separately from the first component 12. The motor vehicle is designed, for example, as a motor vehicle, in particular as a passenger car, commercial vehicle, or truck. The elastomer bearing 10 can be understood, in particular, as a rubber bearing.

[0019] The first component 12 is, for example, a drive device of the motor vehicle, a wheel suspension, or a chassis. The second component is, for example, a frame or a, in particular, self-supporting, body of the motor vehicle. Of course, it is alternatively also possible for the second component 14 to be the drive device, the wheel suspension, or the chassis, and for the first component 12 to be the frame or the body. The drive device is designed, for example, as an electric machine and / or as an internal combustion engine.

[0020] The elastomer bearing 10 has at least one first fastening region 16. For example, the first fastening region 16 is formed by a first bearing part of the elastomer bearing 10. Thus, the elastomer bearing 10 has, for example, the first bearing part, which has the first fastening region 16. The elastomer bearing 10 is to be held or is held, in particular at least indirectly or directly, on the first component 12 of the motor vehicle via the first fastening region 16, in particular via the first bearing part. In other words, the elastomer bearing 10 can be or is fastened to the first component 12 via the first fastening region 16.

[0021] The elastomer bearing 10 has at least one second fastening region 18 that is different from the first fastening region 16, in particular spaced apart from the first fastening region 16. The second fastening region 18 is formed, for example, by a second bearing part of the elastomer bearing 10, which is formed, in particular, separately from the first bearing part. Thus, the elastomer bearing 10 has, for example, the second bearing part, which has the second fastening region 18. The elastomer bearing 10 is to be held or is held via the second fastening region 18, in particular at least indirectly or directly, on the second component 14 of the motor vehicle, which is different in particular from the first component 12. In other words, the elastomer bearing 10 can be or is fastened via the second fastening region 18, in particular at least indirectly or directly, to the second component 14.

[0022] Because the elastomer bearing 10 is held or retained on the respective component 12, 14 via the respective fastening region 16, 18, the first component 12 is to be mounted or retained on the second component 14 by means of the elastomer bearing 10 and / or the second component 14 is to be mounted or retained on the first component 12 by means of the elastomer bearing 10. This means that the first component 12, which is or is to be mounted in particular on the first fastening region 16, is to be held or retained on the second component 14, which is or is to be mounted in particular on the second fastening region 18, via the elastomer bearing, in particular so as to be movable relative to the second component 14.Alternatively or additionally, the second component 14, which is arranged or to be arranged in particular on the second fastening region 18, is movable via the elastomer bearing 10, in particular relative to the first component 12, and is held or held on the first component 12, which is arranged or to be arranged in particular on the first fastening region 16.

[0023] For example, at least one of the bearing parts is made of plastic, in particular of an elastomer. Alternatively, it is possible for the first and second bearing parts not to be made of any plastic. For example, the elastomer bearing 10, particularly when the bearing parts are not made of plastic or the elastomer, has at least a third bearing part made of an elastomer. The third bearing part is arranged, for example, between the first and second bearing parts.

[0024] In order to particularly simplify assembly of the elastomer bearing 10 on the respective component 12, 14, in particular on the first and / or second component 12, 14, it is provided that at least one adhesive 24 embedded in a sheathing material 22 by means of microencapsulation 20 is or will be arranged at least on the first of the fastening regions 16, in particular directly. In particular, adhesive 24 embedded in at least one respective sheathing material 22 by means of respective microencapsulation 20 can be arranged on the first and second fastening regions 16, 18. Of course, it is possible for the adhesive 24 embedded in the sheathing material 22 by means of microencapsulation 20 to be arranged exclusively on the first or second fastening region 16, 18 with respect to the fastening regions 16, 18.Thus, the elastomer bearing 10 is an elastomer bearing with a microencapsulated adhesive 24 applied, in particular, to the first and / or second fastening areas 16, 18. This allows the elastomer bearing 10, which has the adhesive 24, to be transported safely to its installation location, particularly with minimal effort. In particular, the elastomer bearing 10 can be transported as bulk material, thus requiring minimal effort. For example, the casing material 22 is a plastic.

[0025] In the exemplary embodiment shown in the single figure, a respective adhesive 24, which is embedded in a respective casing material 22 by means of microencapsulation 20, is arranged on the first fastening region 16 in a plurality of, for example three, adhesive regions 26, 28, 30, in particular spaced apart from one another.

[0026] It is preferably provided that when arranging the respective component 12, 14, in particular the first and / or second component 12, 14, on the respective fastening region 16, 18, in particular on the first and / or second fastening region 16, 18, by, in particular mechanically, applying pressure to the enveloping material 22 from the respective component 12, 14, in particular from the first and / or second component 12, 14, the enveloping material 22 can be broken open or is broken open at least in regions in order to bond the elastomer bearing 10 and the respective component 12, 14, in particular the first and / or the second component 12, 14, via the respective fastening region 16, 18, in particular via the first and / or second fastening region 16, 18, by means of the adhesive 24. As a result, the elastomer bearing 10 can be bonded to the respective components 12, 14, in particular to the first and / or second components 12, 14, with particularly little effort.Breaking open the wrapping material 22 can be understood in particular as damaging the wrapping material 22.

[0027] For example, it is provided that the first fastening region 16 has an outer side 34 facing outward in the radial direction 32 of the elastomer bearing 10. In other words, the first bearing part is designed as an outer part, in particular as an outer shell. Thus, the microencapsulated adhesive 24 can be applied to an outer surface of the elastomer bearing 10 in the form of the first fastening region 16.

[0028] In the exemplary embodiment shown in the single figure, the first component 12 has a receiving opening 36, in particular designed to correspond to the first fastening region 16, in which the elastomer bearing 10 or the first fastening region 16, in particular the first bearing part, can be arranged or is arranged. In particular, the elastomer bearing 10 can be pressed into the receiving opening 36 via the first fastening region 16, in particular via the first bearing part.

[0029] For example, the second fastening region 18 has an inner side facing inward in the radial direction 32 of the elastomer bearing 10. Thus, the elastomer bearing 10 has, for example, an opening formed, in particular at least partially or completely, by the second fastening region 18 or the second bearing part, in which opening a receiving element of the second component 14, in particular for connecting the elastomer bearing 10 to the second component 14, can be arranged or is arranged. The opening is preferably designed to correspond to the receiving element.

[0030] According to the invention, the first fastening region 16 has at least one recess 38 in which the adhesive 24 embedded in the enveloping material 22 by means of microencapsulation 20 is arranged. In other words, the adhesive 24 embedded in the enveloping material 22 by means of microencapsulation 20 is applied into the recess. The recess is designed, for example, as a pocket. For example, the respective adhesive region 26, 28, 30 is each designed as a respective recess 38.

[0031] Of course, it is alternatively or additionally also possible for the second fastening region 18 to have at least one recess in which adhesive 24 embedded in the casing material 22 by means of microencapsulation 20 is or will be arranged.

[0032] Also disclosed is a method, in particular for arranging the elastomer bearing 10 on the first and second components 12, 14. For example, in the method, adhesive 24 embedded in at least one sheathing material 22 by means of microencapsulation 20 is arranged or applied to the first and / or second fastening region 16, 18, in particular at a first location. The elastomer bearing 10 is then transported, for example, to a second location that is different from the first location, in particular spaced from the first location, which second location can be referred to, in particular, as an assembly location. The elastomer bearing 10 is preferably arranged on the components 12, 14 after the microencapsulated adhesive 24 has been arranged. This means that the elastomer bearing 10 is arranged on the components 12, 14, for example, at the assembly location, and in particular after the elastomer bearing 10 has been transported.

[0033] Preferably, when arranging the elastomer bearing 10 to the components 12, 14, at least one of the components 12, 14 is bonded to the elastomer bearing 10 using the microencapsulated adhesive. Thus, for example, the elastomer bearing 10 is arranged on the first component 12 via the first fastening region 16, to which adhesive 24 embedded in the enveloping material 22 is arranged or applied by means of microencapsulation 20, in particular in order to bond the elastomer bearing 10 via the first fastening region 16 using the, in particular embedded, adhesive 24.Alternatively or additionally, the elastomer bearing 10 is arranged on the second component 14 via the second fastening region 18, to which adhesive 24 embedded in the enveloping material 22 is arranged or applied by means of microencapsulation 20, in particular in order to bond the elastomer bearing 10 to the second component 14 via the second fastening region 18 by means of the, in particular embedded, adhesive 24.
