Definitions

  • the present invention relates to a decoupling element, in particular a vibration decoupling element, and a method for producing a component connection.
  • Decoupling elements or vibration decoupling elements are used, for example, in vehicle construction to protect components or attachments from vibrations.
  • the basic idea is that two components are not connected directly to one another, but rather indirectly via such a decoupling element, which then makes it possible to avoid or dampen vibration transmission from one element to the other, etc. Since such elements are sometimes high in operation and, above all,... are exposed to recurring loads, ensuring a sufficient service life is a major challenge. It is also important to design such elements in such a way that they are easy to assemble.
  • a decoupling element in particular a vibration decoupling element, comprises a base element which extends along a longitudinal axis and which is formed by two partial elements which are arranged along the longitudinal axis, wherein the base element has a first arrangement section on its outer circumference, in particular for a first component, and wherein the base element has an opening which extends along the longitudinal axis, wherein a holding element is arranged in the opening, which forms a second section, in particular for the arrangement of a second Component, and wherein the holding element is designed to fix the sub-elements to one another along the longitudinal axis.
  • the multi-part nature of the base element enables particularly easy assembly.
  • the holding element ensures that the sub-elements can be fixed to one another. It is or can be ensured that none of the sub-elements are lost during assembly of the decoupling element.
  • the holding element can be inserted into the base element formed by the sub-elements and, according to one embodiment, can lock into at least one of the sub-elements, for example, in such a way that they are securely fixed to one another.
  • the base element and the holding element are designed to be rotationally symmetrical.
  • the partial elements which, as will be explained later, are expediently identical parts.
  • the first arrangement section is expediently designed as a circumferential groove.
  • the groove cross section can be angular, trapezoidal, round, oval, etc.
  • the first arrangement section has a constant or uniform contour in the circumferential direction, see the aforementioned “circumferential” groove. However, this is not absolutely necessary. Depending on the geometry of the component to be arranged, other shapes may also be possible and useful.
  • the first arrangement section can also be designed, for example, as a web or projection, which is designed to engage in a corresponding groove of, for example, the first component.
  • the first arrangement section is formed by two insert elements which are arranged in the sub-elements, in particular embedded there.
  • a corresponding insert element is expediently arranged in each of the sub-elements, for example to form a circumferential groove with, for example, an angular cross-section.
  • the insert elements are made of a harder material than the base element or the sub-elements.
  • the insert elements are made of a plastic, preferably for example polyamide.
  • these insert elements formed from the plastic are vulcanized into the sub-elements.
  • Preferred materials for the sub-elements or the basic element are, for example, rubber materials such as EPDM (ethylene-propylene-diene rubbers).
  • Preferred Shore hardnesses are in a range of 35-55 ShA, particularly preferably around 45 ShA.
  • the insert elements have a different color than the sub-elements. This ensures that the arrangement of the sub-elements along the longitudinal axis is not mixed up.
  • the holding element is also made of a plastic, for example polyamide.
  • the base element in particular on the front side, has an inner stop and an outer, each annular, axial stop, the inner stop being designed to be higher than the outer stop.
  • the inner stop projects beyond the outer stop along the longitudinal axis.
  • the inner stop is designed, for example, as an annular web which extends along the longitudinal axis.
  • Contact with another component or a fastener is effected in the axial direction via the inner stop.
  • the decoupling element expediently has a small contact or stop surface indirectly via the inner stop, in other words it requires little installation space. In the axial direction, therefore, no large-area contact surface is provided, but rather only a more or less thin, in particular annular, web, which extends at least essentially along the axial direction or longitudinal direction.
  • the opening formed in the base element along the longitudinal axis is preferably cylindrical or tubular. It is used in particular to arrange the holding element.
  • the opening has at least two webs oriented transversely to the longitudinal axis, on which the holding element is arranged, in particular radially.
  • the holding element does not rest on the base element over its entire surface, but only indirectly via the webs, i.e. only in certain areas. Since the webs are preferably designed to be thin-walled, this can with very good vibration decoupling, especially at high frequencies.
  • such a web is formed on one of the sub-elements along the longitudinal axis.
  • several webs can also be provided, although these do not necessarily have to be oriented transversely to the longitudinal axis, but can also be inclined, oblique, or thread-shaped.
  • each sub-element has two webs along the longitudinal axis, with the respective outer web being shaped in such a way that it not only serves to arrange the holding element, but also acts as the aforementioned inner stop.
  • the outer web is, for example, inclined or curved approximately towards a central or longitudinal axis of the base element.
  • the holding element has a tubular base body, on which a protective element, in particular a circular disk-shaped one, is formed on the front side, which extends transversely to the longitudinal axis, and which is designed to cover the base body at least in some areas on the front side.
  • the holding element is preferably made of a robust material, in particular a robust plastic, such as polyamide.
  • the protective element can expediently cover the base element at least partially on the front side, so that any fastening means used to lock or fasten the decoupling element to a component cannot damage the soft and sensitive base element.
  • the protective element expediently acts as a stop, which is necessary for fixing the sub-elements along the longitudinal axis.
  • the base body has a form-fitting element for fixing the partial elements, which is designed to interact with at least one of the partial elements in a form-fitting and/or force-fitting manner.
  • the form-locking element whereby several such form-locking elements can also be provided, is expediently designed to enable the holding element to be locked or the like with the base element or at least one of the sub-elements. This means that the holding element cannot be pulled out of the base element along the longitudinal axis without a certain amount of force.
  • the form-fitting element is designed as a projection directed circumferentially and radially outwards on the base body.
  • This projection or extension is expediently designed to engage in a correspondingly designed engagement area of the base element or the sub-elements.
  • the aforementioned construction can also be designed in the opposite way.
  • an engagement area in the form of a recess or the like is formed on the base body, in which a projection or extension of the base element or the sub-element engages.
  • the sub-elements are preferably identical parts. This is particularly advantageous in terms of cost.
  • the insert elements preferably arranged or inserted in the sub-elements which are preferably made of a low-wear or less wear-resistant material than the sub-elements, are designed in a different color in order to ensure or support correct installation or error-free assembly.
  • the invention also relates to a method for producing a component connection, wherein a first component and a second component are connected via a decoupling element according to the invention, wherein the decoupling element is only assembled when the component connection is produced.
  • This approach is characterized in particular by very good installability. Above all, it can also be ensured that the decoupling element is not damaged or destroyed during assembly, for example by the application of impermissibly high forces.
  • the assembly of the decoupling element expediently goes hand in hand with its arrangement on one of the components.
  • the method comprises the steps:
  • the base element formed by the sub-elements has, for example, a groove-shaped and circumferential arrangement section on its outside, which cooperates in a form-fitting manner with the opening of the first component.
  • the second component comprises, for example, a bolt or the like, which is guided through the second arrangement section formed by the holding element.
  • the bolt has, for example, a groove or the like on the front side, in which a fastening element can be arranged.
  • the decoupling element is thus fixed in the axial direction, i.e. along the aforementioned bolt.
  • the protective element is expediently formed on the front side, which prevents the fastening element from directly contacting the base element and possibly damaging it.
  • the method comprises the step:
  • a positive and/or non-positive connection is expediently provided between the holding element and the base element or at least one of the sub-elements, such as a latching or snap connection.
  • this is designed in such a way that at the same time a compression or tensioning of the sub-elements along the longitudinal axis is caused.
  • the shape and/or position of the engagement areas or the form-fitting elements are positioned accordingly.
  • the aforementioned is supported Prestressing or compression also via the arrangement of the fastening element, which fixes the holding element indirectly via the protective element along the longitudinal axis relative to the bolt of the second component.

  • Fig. 2 an embodiment of a holding element
  • Fig. 3 the components known from Figures 1 and 2, assembled to form a decoupling element

  • Fig. 1 shows two sub-elements 40, which are arranged spaced apart from one another along a longitudinal axis L.
  • the two sub-elements 40 are designed to form a basic element 10. For this purpose, they are arranged together along the longitudinal axis L, see also FIG. 3 in this regard.
  • Each of the sub-elements 40 comprises an insert element 42, which forms a first arrangement section in the assembled state of the decoupling element.
  • the insert elements 42 are preferably made of a harder, in particular more wear-resistant, material than the insert elements 40.

  • Fig. 2 shows an embodiment of a holding element 60, which comprises a base body 66, which is tubular or cylindrical. Inside, the holding element 60 forms a second arrangement section 62 for arranging a component.

  • the base body 60 does not rest flat on the base element 10 or the sub-elements 40. Instead, the sub-elements 40 each have webs 22, against which the holding element 60 or its base body 66 rests.
  • the sub-elements 40 each have an inner stop 14 and an outer stop 16 on the front side.
  • the inner stops 14 are also web-shaped and subsequently also serve to arrange the holding element 60.
