Outer sleeve of a connection element without a female thread and having a damping function, connection element comprising an outer sleeve, and corresponding connection and manufacturing method

A connection element without a female thread with a damping function with which at least a first component and a second component are connectable by means of a screw connection, comprising the following features:

• a. an outer sleeve having:
• an elastic outer body with a sleeve-like shaft having a fastening flange at a first axial end and, adjacent to a second axial end, a hollow-cylindrical folding zone which is foldable to form a compression bead so that the first component can be supported between the fastening flange and the compression bead,
• a first inner diameter in a portion of the fastening flange and a second inner diameter in a portion of the hollow-cylindrical folding zone, wherein the first inner diameter is larger than the second inner diameter and the second component is attachable adjacent to the second axial end,
• a first as well as a third fastening feature in the portion of the hollow-cylindrical folding zone adjacent to the second axial end at a radial inside,
• b. a spacer sleeve with a third inner diameter that is arranged completely in the outer sleeve adjacent to the second axial end, wherein the spacer sleeve has a second and a fourth fastening feature interacting with the corresponding first and third fastening features of the outer sleeve and the second and fourth fastening feature of the spacer sleeve are beads or grooves and the first and third fastening feature of the outer sleeve are corresponding complementary forms,
• c. a screw with a first outer diameter, wherein the first outer diameter is smaller than the third inner diameter of the spacer sleeve, so that the screw is arranged in the outer sleeve with a radial play in a plane perpendicular to a longitudinal axis of the outer sleeve and that the second component is fixable by means of the screw adjacent to the second axial end of the outer sleeve of the connection element,
• d. a tolerance compensation disc arranged on a shaft of the screw, having a second outer diameter that is smaller than the first inner diameter of the outer sleeve so that the tolerance compensation disc is arranged with a radial play in the outer sleeve,
• e. a holding disc, an inner diameter of which is smaller than the second outer diameter of the tolerance compensation disc, but larger than an outer diameter of a head of the screw, and a radial outer portion of which engages a holding feature at a radial inside of the outer sleeve adjacent to the first axial end, so that the tolerance compensation disc is arranged with a radial play and is held in an axial direction due to the holding disc, wherein
• f. a screwing in of the screw causes a compression of the outer sleeve and thus a formation of the compression bead and takes place until the spacer sleeve prevents a further screwing so that the first component is arranged between the compression bead and the fastening flange, whereas the second component abuts the second axial end of the outer sleeve as well as the spacer sleeve.
