Definitions
- the invention relates to vibration and structure-borne noise-isolating bearings according to the preamble of claim 1.
- Known bearings of this type usually consist of block-shaped elastomers.
- the spring clips are advantageously in one another in the direction of their upright ⁇ axis.
- the individual spring clips can be designed in the form of a spring band comprising a plurality of individual spring clips, or individual spring clips can also be fastened to, for example, a strip-shaped connecting element and can be assembled together with the latter.
- the spring clips can be integrated as supporting structural components in the support elements.
- the spring clips can cooperate with additional other vibration and / or structure-borne noise isolating means.
- this floor can be designed, for example, as a composite or sandwich plate with the spring clips.
- the spring clip is not an integral part of the support element istlagernden ie, in particular the driving ⁇ generating soil, they are each fixed to the latter and the receiving carrier of the vehicle to connect. This can extremely efficient and functionally safe, for example with screw connections.
- FIG. 1 is a perspective view of an only schematically represented installation of an isolated vehicle floor
- FIG. 2 is a view of a bearing constructed from two spring clips of different heights
- Fig. 3 is a 'top view of the bearing of FIG. 2.
- a plate-shaped base is mounted on vibration-protected and structure-borne sound insulation by means of ⁇ -shaped spring clips 4 which are combined into groove-shaped spring clips 3.
- the spring bands 3 with the individual ⁇ -shaped spring clips 4 are made of spring steel.
- the Single ⁇ NEN spring strips 3 are spaced parallel and perpendicular arranged to extend to each other.
- a side wall 5 of the vehicle that is firmly connected to the carrier 1 the bottom 2 is not supported mechanically.
- a distance to be provided here between the floor 2 and the side wall 5 is only provided with a cover which does not hinder the lateral movement of the floor 2 and which only has an aesthetic and dirt-repellent function.
- the spring bands 3 By designing the spring bands 3 in terms of material and shape, with a specialist knowledge that is suitable for this purpose, a mechanically stable support of the base 2 can be achieved in a simple manner with excellent vibration and structure-borne sound insulation in a particularly low frequency range.
- the spring bands 3 can be attached to the base 2 on the one hand and to the support 1 on the other hand in a simple manner by means of screws to be attached when the base 2 is installed.
- a bearing 6 constructed from two nested, ⁇ -shaped spring clips, namely a first spring clip 4 ⁇ and a second spring clip 4 , ⁇ , is screwed firmly onto a carrier 1.
- the fixed connection consists of a strip-shaped band 7, to which the spring clips A 4 ⁇ several bearings 6 can be fastened, and a screw connection of the strip-shaped band 7 to the carrier 1.
- the two spring clips 4 and 4 are disposed in the bearing 6, which form mutually perpendicular.
- the spring clips 4 4 , ⁇ have an ⁇ -like shape, that is, there is a U-shaped basic shape with Z-shaped U-legs. With elastic material, for example spring steel, this results in a spring effect in the direction of the upright axis of a ⁇ -shaped spring clip 4 4 v .
- the elongated lower spring clip 4 ⁇ expediently has the larger spring constant ⁇ te, that is to say the first spring clip 4 ⁇ is then softer than the second spring clip 4 b ⁇ .
- Different spring ⁇ constants can with the two spring clips 4 ⁇ and 4 x be caused by different material properties and / or shape. For example, spring clips of different widths or spring clips of the same shape with different material thickness can be used.
- a bearing 6 with only two spring brackets 4 4 ⁇ is shown, such a bearing may be basically composed of a plurality of such spring clip 4 4, be constructed with possibly different spring constants.
- strip-shaped strips 7 can have prefabricated bearings 6 and can therefore be installed as strip-shaped strips 7 with a large number of bearings 6. It may be expedient to already firmly connect the individual spring clips 4 ⁇ , 4 of a bearing 6 to one another at their zenith. In principle, however, it is also possible to establish the fixed connection in the zenith of the spring clips 4 ⁇ 4 ⁇ only when connected to a support element. If the spring clip 4 is already in its ⁇ zeniths firmly connected together before a connection with the support elements takes place, so the bearing 6 with egg ⁇ ner mounting means is provided for securing the support element. 2
