Definitions

  • the invention relates to vibration and structure-borne sound insulating bearing according to the preamble of patent claim 1.
  • bearings of this type usually consist of block-shaped elastomers, cf. eg US-A-4,869,479 ,
  • the individual bearings expediently each consist of a pair of mutually interacting, different levels of spring clip.
  • the spring clip can advantageously be in one another, and in particular connected to each other, for example, be screwed.
  • the spring clip are in the direction of the upright ⁇ -axis expediently into each other.
  • those spring clips the height of which in the prestressed state is lower than in the relaxed state, should have a smaller spring constant than the other spring clips whose height in the prestressed state is greater than in the relaxed state.
  • the individual spring clips may be formed in the form of a plurality of individual spring clips comprehensive spring band or it may also be fixed individual spring clips on, for example, a strip-shaped connecting element and be mounted together with this.
  • bearings according to the invention can each comprise two spring clips, which are arranged perpendicular to one another by rotation about their respective upright axis. In a nested arrangement of at least two spring clips they can be screwed together in their closed zenith areas.
  • a material for the spring clip according to the invention is particularly suitable steel.
  • the spring clips can be integrated as load-bearing structural components in the support elements.
  • the spring clip can cooperate with additional other vibration and / or structure-borne sound insulating means.
  • the spring clips according to the invention can have such a mechanical stability, in particular when used in a structural composite, that when used as a bearing for a floor of a vehicle in the vehicle vertical axis they only have to be mounted in a space below the floor to be insulated. So here are no lateral supports as they usually have to be used in supports made of elastomers required.
  • a particular advantage of the invention further consists in that the spring clip, in particular in the formation of a plurality of spring clips comprising structural part shape and material can be designed for isolation of low frequencies.
  • the vehicle-side floor mount for the bearings may be a closed underbody or a vehicle frame construction.
  • this floor may be formed, for example, as a composite or sandwich plate with the spring clips. If the spring clips are not an integral part of the Auflagagernden support element, ie in particular of the vehicle floor, they are each firmly connected to this and the receiving carrier of the vehicle. This can For example, by screw extremely rational and functionally safe done.
  • a plate-shaped bottom is mounted on groove-shaped spring bands 3 combined ⁇ -shaped spring clip 4 vibration and structure-borne sound insulation.
  • the spring bands 3 with the individual ⁇ -shaped spring clips 4 are made of spring steel.
  • the individual spring strips 3 are each arranged spaced parallel and perpendicular to each other. Opposite a fixedly connected to the carrier 1 side wall 5 of the vehicle the bottom 2 mechanically unsupported. A distance to be provided here between the floor 2 and the side wall 5 is merely provided with a cover which does not hinder the lateral movement of the floor 2 and which has only aesthetic and dirt-repellent function.
  • a bearing 6 constructed of two nested, ⁇ -shaped spring clips, namely a first spring clip 4 'and a second spring clip 4 ", is screwed tightly onto a carrier 1.
  • the vehicle wheels can be mounted on this carrier 1
  • Connection consists of a strip-shaped band 7, to which the spring clip 4 ', 4 "of several bearings 6 can be attached and a screw connection of the strip-shaped band 7 with the carrier.
  • the two spring clips 4 'and 4 are arranged perpendicularly to one another in the bearing 6 which they form.
  • the spring clips 4', 4" have an omega-like shape, that is to say a U-shaped basic shape having a U-shaped U -Children in front. This results in elastic material, such as spring steel, a spring action in the direction of the upright axis of a ⁇ -like shaped spring clip 4 ', 4' '.
  • the spring clips 4 ', 4 "of a bearing 6 touch each other and are screwed together there in a screwed state of the spring clip 4', 4 '', that is, when the state of the spring clips 4 ', 4" is in a functional condition 6, the two spring clips 4 ', 4 "braced against each other.
  • the spring height L is less than the spring height h 1 before installation.
  • h 2 has a reduced spring height compared to 1.
  • the first spring clip 4 ' is compressed in the illustrated bearing, while the second spring clip 4" is stretched.
  • the elongated lower spring clip 4 "expediently has the larger spring constant when the two spring clips 4 ', 4" with different spring constants are formed, that is to say the first spring clip 4' is designed to be softer than the second spring clip 4 " two spring clips 4 'and 4 " caused by different material properties and / or shaping.
  • differently wide spring clips or identical spring clips with different material thickness can be used.
  • a bearing 6 with only two spring clips 4 ', 4 " is shown, such a bearing can in principle be composed of a plurality of such spring clip 4', 4 '' with optionally different spring constants.
  • strip-shaped bands 7 can have prefabricated bearings 6 and thus be installed as a strip-shaped belt 7 with a plurality of bearings 6. It may be expedient to connect the individual spring clips 4 ', 4 "of a bearing 6 firmly to each other at the zenith thereof, but in principle it is also possible for the firm connection at the zenith of the spring clips 4', 4" to be effective only during connection to produce a support element. If the spring clips 4 ', 4 "are already firmly connected to one another in their zeniths before being connected to the support elements, then the bearing 6 is to be provided with a fastening device for fastening the support element 2.
