A covering means is provided for a component of an electrical drive system having or consisting of a first metallic layer, wherein the first metallic layer is equipped to be vibration-damping.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A covering means for a component of an electrical drive system having or consisting of a first metallic layer, wherein the first metallic layer is equipped to be vibration-damping, wherein the first metallic layer has first regions in which the first metallic layer has at least one cutout, and wherein for one, a plurality of, or all of the first regions, the first region has a cutout, with a diaphragm being arranged encircling the peripheral edge of the cutout and/or completely covering the cutout. 2 . The covering means according to claim 1 , wherein the first metallic layer is provided at least in regions with a vibration-damping material on one of the surfaces of the metallic layer. 3 . The covering means according to claim 2 , wherein the vibration-damping material is or contains silicone-based or polyurethane-based material. 4 . The covering means according to claim 2 , wherein the vibration-damping material contains rubber or bitumen. 5 . The covering means according to claim 2 , wherein the vibration-damping material contains a mineral additive. 6 . The covering means according to claim 1 , wherein the vibration-damping material is or contains a further metallic layer or a fibre mat. 7 . The covering means according to claim 6 , wherein the vibration-damping material is glued to, laid on, soldered on or welded to the first metallic layer. 8 . The covering means according to claim 1 , wherein the covering means is a housing. 9 . The covering means according to claim 8 , wherein the housing is equipped to be vibration-damping such that vibrations, incited by sound waves, of between 6 and 12 kHz emerging from the interior of the housing in the housing are damped. 10 . The covering means according to claim 1 , wherein the first metallic layer is coated on the outer side and/or inner side of the covering means with a metal. 11 . The covering means according to claim 1 , wherein the first metallic layer in regions has a dimpled and/or ribbed and/or cross-ribbed texture. 12 . The covering means according to claim 1 , wherein for one, a plurality of or all the first regions, the first region has a reduced thickness and is equipped to be vibration-damping. 13 . The covering means according to claim 1 , wherein for one, a plurality of or all the first regions the diaphragm is injection-moulded or glued onto the peripheral edge of the cutout. 14 . The covering means according to claim 1 , wherein the first metallic layer in the contact region with a further element is coated. 15 . An electric motor or inverter of an electric motor, wherein it has a covering means according to claim 1 which surrounds an electric motor or an inverter of the electric motor at least in regions.
