Device and method for heat and noise insulation of motor vehicles

Abstract

A device for heat and noise insulation has a first carrier layer rigidly connected with a component to be insulated, particularly an oil-carrying element of an internal combustion engine, as well as an insulating layer with a plurality of individual damping elements, particularly fiber or honeycomb elements which are individually connected with the carrier layer and/or joined to it in articulated manner. An air cushion is formed between the individual damping elements within the insulating layer and/or between the carrier layer and the insulating layer. The cushion can be changed by adjusting several of the damping elements, the entire insulating layer and/or the carrier layer. A method for insulating comprises connecting the carrier layer to a component to be insulated and attaching a plurality of the damping elements to the carrier layer, with the air cushion being formed between the damping elements, within the insulating layer or between the carrier layer and the insulating layer.

1 . A device for heat insulation and noise insulation of a component, comprising: 
 a first carrier layer adapted to be rigidly connected with the component to be insulated; and    an insulating layer having a plurality of individual damping elements that are individually connected with the carrier layer in an articulated manner;    wherein an air cushion is formed between the individual damping elements, within the insulating layer or between the carrier layer and the insulating layer, said cushion being changeable by adjusting several of said damping elements, the entire insulating layer, or the carrier layer.    
     
     
         2 . Device according to  claim 1 , wherein several of said damping elements are elastic fibers made of a material having poor heat conduction properties, said fibers being adjustable by way of an air stream.  
     
     
         3 . Device according to  claim 1 , wherein several of said damping elements are fibers having shape-changing properties, said fibers being adjustable by way of a thermal or electrical control that turns said fibers on.  
     
     
         4 . Device according to  claim 1 , wherein several of said damping elements are movably mounted honeycomb elements that are adjustable in their position or orientation by way of said carrier layer.  
     
     
         5 . Device according to  claim 1 , wherein several of said damping elements are honeycomb elements arranged to be immovable relative to the component to be insulated when said device is connected with the component to be insulated, and wherein movable honeycomb elements are mounted between the immovable honeycomb elements.  
     
     
         6 . Device according to  claim 1 , wherein several of said damping elements are honeycomb elements arranged to be immovable relative to the component to be insulated when said device is connected to said component to be insulated, and wherein the immovable honeycomb elements demonstrate shape-changing properties and can be adjusted by a thermal or electrical turn-on control imparted by way of the carrier layer.  
     
     
         7 . Device according to  claim 1 , wherein the insulating layer has several air pockets separated from one another and wherein one of said damping elements is arranged in at least one of the air pockets.  
     
     
         8 . A method for providing heat insulation or noise insulation in motor vehicles, comprising; 
 connecting a carrier layer with a component to be insulated; and    individually connecting a plurality of individual damping elements with the carrier layer to form an insulating layer,    wherein an air cushion is formed between the individual damping elements, within the insulating layer or between the carrier layer and the insulating layer, which cushion is changed by adjusting several damping elements, the entire insulating layer or the carrier layer.    
     
     
         9 . Method according to  claim 8 , wherein several of said damping elements are elastic fibers made of a material having poor heat conduction properties, which fibers are adjustable by way of an air stream.  
     
     
         10 . Method according to  claim 8 , wherein several of said damping elements are fibers having shape-changing properties, which are adjusted by way of a thermal or electrical control that turns them on.  
     
     
         11 . Method according to  claim 8 , wherein several of said damping elements are implemented as movably mounted honeycomb elements that are adjusted in their position or orientation by way of a carrier layer that can be turned on or moved.
