DETAILED DESCRIPTION

[0042] FIGS. 1 to 7 show an assembly bearing 10 according to a first embodiment, said bearing being used to mount a motor vehicle assembly (not illustrated), such as, for example, an internal combustion engine, a transmission or an electric motor, on a vehicle body (not illustrated). The assembly bearing 10 insulates the vibrations generated by the motor vehicle assembly and also damps roadway excitations.

[0043] As can be seen from FIGS. 1, 4 and 7 when considered together, the assembly bearing 10 has an inner part 12, an elastomeric supporting body 14 in which the inner part 12 is embedded, and an outer part 16 which surrounds the supporting body 14.

[0044] The inner part 12 is composed of metal and has a passage opening 18 into which a supporting arm or bolt (not illustrated) can be inserted in order to connect the assembly bearing 10 to a motor vehicle assembly.

[0045] As can be seen in particular in FIG. 7, the elastomeric supporting body 14 surrounds the inner part 12, wherein the supporting body 14 is connected to the inner part 12 in a materially bonded manner, in particular is injection-molded and/or vulcanized thereon. The supporting body 14 has a first supporting spring 20 which projects from the inner part 12 in the radial direction R.

[0046] In the present case, the outer part 16 is configured in the form of an outer sleeve and has a first part 22 and a second part 24 which, as per FIGS. 1, 2 and 5, are configured in the form of half-shells 26 and are connected to one another at opposite abutment surfaces 54. The two half-shells 26 are composed of plastic, in particular fiber-reinforced plastic, but can also be composed of metal. Each of the half-shells 26 surrounds one half of the supporting body 14.

[0047] In order to fasten the two half-shells 26 to the supporting body 14, said body has a fastening element 28 in the form of a ring element 30 which is connected to the first supporting spring 20 in a positively locking, force-fitting and/or materially bonded manner.

[0048] As can be seen in particular in FIGS. 2 and 3, the ring element 30 is connected to an outer side 32 of the first supporting spring 20, or the ring element 30 surrounds the outer circumference of the first supporting spring 20. The ring element 30 can be pressed onto the outer side 32 of the first supporting spring 20 and/or can be connected thereto in a materially bonded manner, for example by adhesive bonding, by inserting the fastening element 28 into an injection mold and subsequently applying the elastomer of the supporting body 14 by injection molding, or in a 2-component injection-molding process.

[0049] As can be seen from FIGS. 1, 2, 3, 4, 5 and 6 when considered together, the two half-shells 26 are clipped to the supporting body 14, in particular to the fastening element 28. To this end, the fastening element 28 has a pair of protrusions 34, 36 which engage into corresponding cutouts 38 of the half-shells 26 or extend through the cutouts 38.

[0050] As can be seen in particular in FIG. 2, the fastening element 28 has a pair of opposite first protrusions 34 and a pair of opposite second protrusions 36, wherein the first protrusions 34 engage into cutouts 38 of the first part 22, and the second protrusions 36 engage into cutouts 38 of the second part 24. As a result, the two half-shells 26 are clipped to the fastening element 28. During the assembly of the two half-shells 26, the half-shells 26 are deflected in an elastic manner so that the protrusions 34, 36 can be inserted into the cutouts 38.

[0051] As can be seen in particular in FIG. 3, each protrusion 34, 36 has a lead-in chamfer 40 which makes it easier to insert the protrusions 34, 36 into the cutouts 38.

[0052] Between a first protrusion 34 and a second protrusion 36, the fastening element 28 has a respective centering element 42 which is configured in the form of a web 44 which extends in the longitudinal direction L of the assembly bearing. The centering element 42 engages into an opening 48 in a positively locking manner, said opening being formed by two opposite cutouts 38 of the half-shells 26, as can be seen in FIGS. 4, 5 and 6. The centering element 42 is used to center the two half-shells 26 relative to one another and also to position the supporting body 14 between the two half-shells 26.

[0053] As can also be seen in FIGS. 1 and 7, each of the half-shells 26 also has a positively locking connecting element 50 and a corresponding receptacle 52 for the connecting element 50. The connecting element 50 is configured in the form of a pin element 56 which projects from the abutment surface 54, and the receptacle 52 is configured in the form of a blind hole 58 which is introduced into the abutment surface 54 and into which the pin element 56 engages.

[0054] As can also be seen in FIG. 1, a depression 62, which corresponds to the contour of the fastening element 28 and in which the fastening element 28 is inserted in a positively locking manner, is introduced into an inner circumferential surface 60 of each half-shell 26. As a result, the supporting body 14 is fixed in an exact position in the half-shells 26.

[0055] Each of the half-shells 26 has a stop 64 on the inner circumferential surface 60, said stop being spaced apart from the inner part 12 delimiting the movements of the inner part 12 relative to the outer part 16, as can be seen in FIGS. 1 and 7.

[0056] A second embodiment of the assembly bearing 10 is described below, with the same reference designations being used for identical or functionally identical parts.

[0057] FIGS. 8 to 14 show a second embodiment of the assembly bearing 10 which differs from the first embodiment in that the supporting body 14 has a second supporting spring 66, wherein each of the supporting springs 20, 66 is provided with a fastening element 28. In order to clip the two half-shells 26 to the two fastening elements 28, each of the half-shells 26 has four cutouts 38 into which the protrusions 34, 36 engage in the clipped-together state or through which the protrusions 34, 36 project, as can be seen in FIGS. 11 to 13.

[0058] In the present case, the stop 64 is configured in the form of indentations 68 which are introduced into the half-shells 26 and which project radially inward from the inner circumferential surface 60. As can be seen in FIG. 14, in the clipped-together state of the half-shells 26, the indentations 68 are arranged between the two supporting springs 20, 66.

[0059] As can be seen in FIG. 8, the half-shells 26 of the second embodiment have no positively locking connecting element 50 and no corresponding receptacle 52 for the connecting element 50. However, it is also conceivable, in accordance with the first embodiment, for the half-shells 26 to have a positively locking connecting element 50 and a corresponding receptacle 52 for the connecting element 50.

[0060] The assembly bearing 10 is distinguished by the outer part 16 formed of two half-shells 26 which are clipped to a fastening element 28 which is connected to the supporting body 14. As a result of the joining of the two half-shells 26, an encircling geometry is produced, which generates an undercut and thus an overlap which can be utilized as a stop 64. As a result, installation space-related requirements can be met, and also additional components causing additional costs can be avoided.
