Definitions
- the invention relates to a damping element which is arranged between the battery system and the motor vehicle floor.
- the load distribution element is a deformation foam and / or at least one spring element, in particular a spring rail. This arrangement is intended to protect the high-voltage energy storage device against collisions.
- the deformation foam is in particular a metal foam.
- battery cases for example made of metal-coated foam, have been proposed in the prior art to keep the battery warm.
- the battery is not effective during operation. lent warm, so that the shell cannot store any heat. If necessary, this can be used for cold insulation.
- the object of the present invention compared to the aforementioned prior art is thus to provide a (vibration) damping element, especially for electric vehicles, that is arranged between the battery / accumulator system and the vehicle floor, and the mass of the battery / accumulator system to the Coupling the vehicle floor and reducing / damping the sheet metal vibrations.
- a damping element especially for electric vehicles, that is arranged between the battery / accumulator system and the vehicle floor, and the mass of the battery / accumulator system to the Coupling the vehicle floor and reducing / damping the sheet metal vibrations.
- the damping element according to the invention is also used for motor vehicles in which the battery / accumulator system is arranged vertically to / against the bulkhead (front or rear).
- the subject of the present invention is in a first embodiment a damping element 4 for a battery / accumulator system, in particular an electric vehicle, comprising a viscoelastic PUR foam 1 with
- Viscoelastic in the context of the present invention means a partly elastic, partly viscous material behavior.
- the elastic part basically causes a spontaneous, limited reversible deformation, while the viscous part causes a delayed (time-dependent) recovery behavior after compression deformation; and thus the viscoelastic foam 1 exhibits good damping properties.
- the initial thickness of the foam 1 is determined by the gap between the body panel and the battery / accumulator system; the initial foam thickness is in the range from 8 to 30 mm, preferably up to 10 and 20 mm.
- the fleece optionally coated with copper or aluminum and optionally with a corrosion protection layer, in particular on one side, is predominantly a polyester or polyamide spunbond fleece, which is also or at the same time suitable for shielding electromagnetic radiation.
- the essence of the present invention is thus the provision of a damping element 4, which couples the mass of the battery / accumulator system to the vehicle floor, is corrosion-resistant and, if necessary, simultaneously shields electromagnetic radiation and reduces / dampens the sheet metal vibrations.
- the advantage of the present invention is that the damping element 4 reduces and dampens the sheet metal vibrations, thereby reducing or eliminating the weight per unit area of commercially available anti-drumming films and thus reducing the overall weight of the vehicle.
- a measure of the burning behavior of the foam 1 is determined, for example, by the flammability.
- DIN 75200 was developed from the American standard FMVSS 302 (Federal Motor Vehicle Safety Standard). The test procedures are practically identical, in DIN 75200 only the test setup and the execution of the burning test as well as the determination of the burning rate are described, in FMVSS 302 assessment criteria are also specified. The standards were developed to test the burning behavior of materials for vehicle interiors.
- a damping element consisting of a commercially available viscoelastic PUR foam 1 (density 35 kg / m 3 , loss factor 0.4, thickness 20 mm, fulfilling flammability according to FMVSS 302) was used Covered with a chemically bonded polyamide spunbond fleece (80 g / m 2 , coating: copper + anti-corrosion layer). In order to mantel bug vents 3 were arranged. This damping element 4 was then arranged between the vehicle floor and the battery system of a passenger vehicle. The degree of compression of the foam 1 was 40%.
- Fig. 2 the acoustic effectiveness when driving the passenger vehicle at a constant speed of 80 km / h is Darge.
- the diagrams show the acceleration level of the body panel measured on the passenger compartment side when driving at a constant 80 km / h on the road with and without a damping element. In all three measured spatial directions, a significant improvement / level reduction is brought about by the damping element.
