Mounting assembly unit
A mounting assembly unit includes a mounting element ( 12 ) to be fixed by at least one fastening bolt ( 30 ). At least one mounting element passage opening ( 14, 16 ) is provided in the mounting element ( 12 ) for the passage of the at least one fastening bolt ( 30 ). A mounting aid unit ( 18 a, 18 b ) associated with at least one mounting element passage opening ( 14, 16 ) is provided at the mounting element ( 12 ). The mounting aid unit ( 18 a, 18 b ) associated with the mounting element passage opening ( 14, 16 ) has a mounting aid unit passage opening ( 22 a, 22 b ), which is positioned aligned with respect to the mounting element passage opening, such that an edge area ( 28 a, 28 b of the mounting aid unit ( 18 a, 18 b ), which edge area surrounds the mounting aid unit passage opening ( 22 a, 22 b ), is arranged overlapping the mounting element passage opening ( 14, 16 ) in some areas.
1. A mounting assembly unit for preassembling a fastening bolt with a mounting element, comprising:
a mounting element made of metallic material to be fixed to a component by means of at least one fastening bolt, wherein at least one mounting element passage opening is provided in the mounting element for the passage of the at least one fastening bolt;
at least one mounting aid unit made of metallic material with a thickness of less than 0.1 mm, each unit being fixed to the mounting element by welding and defining a mounting aid unit passage opening associated with a respective one of the at least one mounting element passage openings; and
a threaded fastening bold extending through the at least one mounting element passage opening and held by the mounting aid unit,
wherein the at least one mounting element passage opening is elongated and has an opening width obliquely to a direction of longitudinal extension of the mounting element passage opening, the opening width being greater than an external diameter of the fastening bolt,
wherein the mounting aid unit passage opening is elongated and has an opening width obliquely to a direction of longitudinal extension of the mounting aid unit passage opening, the opening width of the mounting aid unit passage opening being smaller than the opening width of the at least one mounting element passage opening,
wherein the mounting aid unit passage opening is positioned aligned with respect to the mounting element passage opening, such that two opposing longitudinal edge sections of an edge area of the mounting aid unit, which surround the mounting aid unit passage opening and extend in the direction of longitudinal extension thereof, overlap the mounting element passage opening at opposing longitudinal ends thereof, and
wherein a distance between the two longitudinal edge sections is shorter than the external diameter of the fastening bolt such that the longitudinal edge sections deformably interlock with the thread of the fastening bolt to retain the bolt in a preassembled condition therewith.
2. A mounting assembly unit in accordance with claim 1 , wherein:
the mounting aid unit comprises a single mounting aid element; and
the mounting aid unit passage opening is an opening formed in the mounting aid element.
3. A mounting assembly unit in accordance with claim 2 , wherein the opening formed in the mounting aid element is closed.
4. A mounting assembly unit in accordance with claim 1 , wherein the mounting aid unit comprises two mounting aid elements arranged so as to provide an intermediate space forming the mounting aid unit passage opening.
5. A mounting assembly unit in accordance with claim 4 , wherein:
each of the two mounting aid elements provides one of the longitudinal edge sections of the edge area.
6. A mounting assembly unit in accordance with claim 1 , wherein the mounting aid unit has a thickness of less than 0.08 mm.
7. A mounting assembly unit in accordance with claim 1 , wherein the mounting aid unit has a thickness of less than about 0.05 mm.
8. A mounting assembly unit in accordance with claim 1 , wherein the at least one fastening bolt is a screw bolt.
