20140216590 | DUCT ELEMENT FOR THE EXHAUST SYSTEM OF A MOTOR VEHICLE - A duct element for the exhaust system of a motor vehicle with an internal combustion engine, including at least one flexible duct part, preferably a bellows. The flexible duct part is embodied at least partially from a first type of steel with a Mo-content ≧4% or ≧6% and with a N-content from 0.3% to 0.6% or from 0.18% to 0.25%, preferably embodied from steel of the type 1.4565 or the type 1.4547. Furthermore a decoupling element is provided for motor vehicles with an internal combustion engine and a respective use of steel embodied with a Mo-content ≧4% or ≧6% and a N-content from 0.3% to 0.6% or from 0.18% to 0.25%, preferably steel of the type 1.4565 or 1.4547. | 08-07-2014 |
20120138185 | METHOD AND PREPROCESSED TUBE FOR PRODUCING A TUBE WITH A BENT PROGRESSION OR A BEND EMBODIED AS A TRAVERSE PROGRESSION - A method and preprocessed tube for producing a tube with a bent progression or bend embodied as a transverse progression. For the bent position of the tube or for each fold of the transverse progression, two miter cuts are made into an essentially straight tube, creating two tube sections with miter cut surfaces extending along cutting planes and a cutting wedge. The miter cuts are placed such that the cutting planes intersect at a point located inside the tube wall, and at this point a bendable bar is left intact connecting the two tube sections. A folding of the miter cut surfaces of the two tube sections onto each other around the bar acting as a hinge allows both tube sections to be welded together around their miter cut surfaces. An additional centering aid formed by a protrusion and a recess can be provided in the opposite miter cut surfaces. | 06-07-2012 |
