Abstract
A system for insulating a structural element in a motor vehicle, including a structural element and a device arranged thereon and having a carrier. The system also includes an expandable adhesive, which is arranged on the structural element or on the carrier via pumping or via extrusion. The carrier and the expandable adhesive are designed and arranged in such a way that the carrier limits the expandable adhesive in at least one direction during the expansion of same.
Claims16
A system for insulating a structural element in a motor vehicle, the system comprising:
- a structural element having a first constituent part and a second constituent part, the constituent parts being joined together at a first joining point and at a second joining point, and the structural element forming a cavity;
- a device having a carrier, the carrier being arranged on the structural element by virtue of a fastening element;
- and
- an expandable adhesive, which is arranged on the structural element or on the carrier by pumping or by extruding within the structural element,
- wherein the carrier and the expandable adhesive are formed and arranged in such a way that the carrier delimits the expandable adhesive in at least one direction as the adhesive expands, and
- a distance between the carrier and the structural element in the at least one direction is smaller than a distance between the carrier and the structural element in a direction opposite to the at least one direction.
A method for insulating a structural element in a motor vehicle, the method comprising the steps of:
- providing a device having a carrier;
- arranging the device on the structural element;
- arranging an expandable adhesive on the structural element or arranging the expandable adhesive on the carrier by pumping or by extruding after the carrier is on the structural element;
- joining a first constituent part and a second constituent part of the structural element to form the structural element, wherein the device and the expandable adhesive are arranged in a cavity between the constituent parts of the structural element;
- and
- expanding the expandable adhesive, the carrier delimiting the expansion of the expandable adhesive in at least one direction.
A system for insulating a structural element in a motor vehicle, the system comprising:
- a structural element having a first constituent part and a second constituent part, the constituent parts being joined together at a first joining point and at a second joining point, and the structural element forming a cavity;
- a device having a carrier, the carrier being arranged on the structural element by virtue of a fastening element;
- and
- a separate expandable adhesive, which is arranged on the structural element by pumping or by extruding, wherein
- the separate expandable adhesive is not applied on the carrier, and
- the carrier and the separate expandable adhesive are formed and arranged in such a way that the carrier delimits the separate expandable adhesive in at least one direction as the adhesive expands.
