Definitions

  • the invention relates to a device and a method for fastening, clamping, or adjusting a molding part to a body-mounted part.
  • Tension struts made of fiber-reinforced plastic are known from WO 96/029483, which include at least one looped bracing element or tensioning element for introducing a tensile force component.
  • a device for fastening, clamping, or adjusting a molding part, in particular an underbody molding, to a body-mounted part, in particular a side member is provided.
  • At least one tensioning element is designed as a tension strut and includes at least one oblong element made of fiber-reinforced plastic, whereby the length of the tensioning element may be adjusted between two end positions via a bracing device.
  • a method for fastening, clamping or adjusting a molding part, in particular an underbody molding, to a body-mounted part, in particular a side member, by way of multiple tensioning elements designed as tension struts, each being fastened via a connecting element to the vehicle-mounted part, in particular the side member, and fastened via another connecting element to the molding part, in particular the underbody molding.
  • the length of the tensioning elements are adjustable between two end positions by way of a bracing device.
  • An oblong element made of fiber-reinforced plastic allows large tensile forces to be absorbed, in particular at high speeds.
  • a length compensation device integrated into the tensioning element allows the length of the tensioning element to be adjusted, as the result of which the molding part may always be readjusted with respect to the body-mounted part.
  • the forces occurring at high speeds may be absorbed by the oblong elements made of fiber composite and transmitted to the base support structure.
  • FIG. 1 is a perspective view of a base structure of a motor vehicle together with a tensioning element according to the invention
  • FIG. 2 shows the tensioning element according to FIG. 1 in an isolated illustration
  • FIG. 3 is an enlarged illustration of the tensioning element according to FIG. 2 in a modified embodiment.
  • FIG. 4 shows a tensioning element in a second embodiment.
  • FIG. 1 illustrates a base structure 1 of a motor vehicle (not further illustrated) in a perspective oblique view taken from above.
  • the direction of travel is identified by an arrow FR.
  • the base structure 1 includes a support structure, which in this illustration is represented as a side member 2 .
  • the base structure 1 is covered by an underbody molding 3 , which is held on the support structure, in particular held flat against the side member 2 .
  • an underbody molding 3 To prevent the underbody molding 3 from being pulled away from the support structure as the result of the increasing negative pressure at high speeds, there must be a stable attachment between the underbody molding 3 and the support structure. It is particularly important that this attachment may always be readjusted. This is achieved via a tension strut 4 , which is designed as a tensioning element 5 .
  • the tensioning element 5 includes two connecting elements 6 and 7 .
  • the connecting element associated with the side member 2 is fastened to the side member 2
  • the connecting element 7 associated with the underbody molding 3 is fastened to the underbody 3 .
  • the tensioning element 5 also includes a bracing element 8 .
  • Extending between the connecting elements 6 and 7 are two carbon fiber-reinforced plastic (CFK) bands 9 and 10 , each of which is deflected at deflection points 11 and 12 so that the CFK bands have a double-layer circulating design in the manner of a loop.
  • CFK carbon fiber-reinforced plastic
  • the deflection point 12 is provided with a reversing bolt 13 which is mounted in bearing receptacles 14 and 15 .
  • the CFK bands 9 and 10 lie against the periphery of the reversing bolt 13 , at least in places.
  • the bearing receptacles 14 and 15 are oriented at right angles to a base plate 16 , which is anchored to the underbody molding 3 via a screw connection 17 .
  • the oppositely situated deflection point 11 is designed as a fork-shaped receptacle 18 having two prongs 19 and 20 .
  • the prongs 19 , 20 accommodate a reversing bolt 21 around which the CFK bands 9 and 10 are guided.
  • CFK bands 9 and 10 are rigidly designed as a molded part made of laminate, and therefore are not flexible.
  • the bracing element 8 is situated between the fork-shaped receptacle 18 and the connecting element 6 .
  • the bracing element 8 includes a threaded rod 22 , which at one end is attached to the receptacle 18 and at the other end is guided in a threaded sleeve 23 .
  • the threaded sleeve 23 cooperates with a threaded rod 24 affixed to the connecting element 6 at the opposite end.
  • the underbody molding 3 may be optimally braced, and tolerances are compensated for. Forces produced from increasing negative pressure are absorbed by the tensioning elements, which act as tension struts.
  • FIG. 3 shows a fork-shaped receptacle 18 ′ in a design that is modified with respect to the receptacle 18 described in FIGS. 1 and 2 .
  • the threaded rod 22 ′ is screwed into the receptacle 18 ′ and secured by a lock nut 25 .
  • the adjustment in length is made by screwing the threaded rod by a greater or lesser degree into the lock nut 25 .
  • FIG. 4 A second embodiment of the invention is shown in FIG. 4 .
  • the tensioning element 5 includes only one CFK band 26 , which is guided around a deflection 27 .
  • a fastening pin 28 Oppositely situated from the deflection 27 is a fastening pin 28 , which is connected to the deflection 27 via a threaded rod 29 .
  • the fastening pin 28 is fixedly connected to a fork support 30 , the two prongs 31 and 32 of which are fastened to the side member 2 .
  • Provided in each prong 31 , 32 is an oblong hole 33 in which a pin 34 projecting from the deflection 27 engages.
  • the distance between the deflection 27 and the fastening pin 28 may be adjusted by way of the threaded rod 29 , resulting in a compensation in length which corresponds to the length of the oblong hole 33 .
  • CFK bands need not have a double-layer design, and instead may be fastened to the receptacle 18 or to the connecting element 7 via appropriate fastenings.
