Definitions
- the invention relates to a front end of a motor vehicle, consisting of frame side members, wheel arches and fenders, one / each on each side, a cross member with a front panel, and a front flap (also called a bonnet), the front flap being flush on each side but with a joint in between, adjoins an edge of the fender, which in turn forms a vertical wall starting from the edge, which is supported on the wheel arch and / or frame side member, and the front flap is resilient downwards when a body hits.
- the flexible front flap is intended to reduce the risk of serious injuries in the event of a collision with a pedestrian - the impacting body is then a human, in particular a head.
- the victim's upper body is usually pivoted backwards and downwards around the vehicle bow, so that the head then hits the front flap in the vertical direction. This is designed to mitigate this impact.
- the vertical wall rests frictionally on a standing plate which is firmly connected to the wheel house or frame side member, the frictional connection between the vertical wall and standing plate being produced by means of a tension element penetrating a hole in the vertical wall and a hole in the standing plate , which brings about a compression spring, and one of the two holes is an elongated hole.
- the frictional connection allows a very precise and reproducible setting of the molding behavior; not only its beginning but also its course.
- the fender can be replaced very easily and without welding, for example after a collision.
- One slot allows the different Exercise the two parts against each other without accompanying deformation of one of the two sheets.
- the standing plate preferably forms an angled foot fastened to the wheel arch or frame side member, corner beads being formed in the angular zone (claim 2). This ensures that the frictional displacement in the event of a collision is not disturbed by premature bending or buckling of the standing plate.
- the vertical wall of the fender extends down to the wheel house or frame side member and its lower edge is rolled in (claim 3).
- the vertical wall of the fender extends down to the wheel house or frame side member and its lower edge is rolled in (claim 3).
- the tension element can be a cap screw and the associated nut attached to the side of the fender facing away from the front flap (claim 5) or the tension element is a bolt with a footplate, the footplate being fastened to the side of the fender facing away from the front flap and the Mother with the front flap open is accessible (claim 6).
- the spring force is particularly precisely definable if the compression spring is at least one plate spring (claim 7), which is designed either in accordance with the standard or as a radially slotted bell.
- FIG. 1 an axonometric view of the upper part of a front vehicle designed according to the invention
- FIG. 2 section according to CC in FIG. 1 in a first embodiment
- FIG. 3 section according to CC in FIG. 1 in a second embodiment
- Fig. 4 Section according to CC in Fig. 1 in a first variant of the second
- Fig. 5 section according to CC in Fig. 1 in a second variant of the second embodiment.
- Fig. 1 the left fender is designated 1 and the right one with 2. Between these there is a front flap 3 (also: bonnet), a front panel 4 connects at the front, which is part of the vehicle bow, and a windshield 5 that is only indicated at the rear.
- a front flap 3 also: bonnet
- a front panel 4 connects at the front, which is part of the vehicle bow, and a windshield 5 that is only indicated at the rear.
- the front flap 3 consists of an outer shell 11 and an inner reinforcement 12, which is designed in a known manner so that it yields in the direction of arrow 9 when a body occurs.
- the left fender 1 adjoins the outer shell 11 interrupted by a joint 14. It forms on the edge 5 of the joint 14 has an edge 13 at which it is bent inwards and merges into a vertical wall 15.
- a standing plate 17 is fastened on the upper flange 8 of the longitudinal beam 7. It has an angled foot 18, which is spot welded to the
- connecting elements 21 are provided, usually several over the length of the fender. At the location of such connecting elements 21 there is a hole 16 (in the vertical wall 15) elongated hole 20 (in the standing plate
- the tension element is here, for example, a cap screw 22 with a nut. Further details of this tension element 21 are described with reference to the next figure.
- FIG. 3 which represents a further development of the subject of FIG. 2, the vertical wall 25 is drawn down into the vicinity of the upper chord 8. It forms a rolled-up lower edge 26 there.
- the edge 26 * is dashed in the event of a collision after the displacement Vertical wall shown. 5
- the standing plate 27 is welded here with its foot 28 to the outside on the upper flange and the elongated hole 29 is provided in the vertical wall 25.
- the tension element 21 is here a threaded bolt 30 which penetrates the standing plate 27 and is fastened to the vertical wall 25 on its rear side by means of a foot plate 31, for example by being punctured.
- the mother 30 ' The mother 30 '
- the compression spring 32 can be a plate spring or a plurality thereof, or bell-shaped as shown. shaped and optionally provided with radial slots. Thanks to the thread and the precisely known spring force of the compression spring 32 and the known coefficient of friction of the friction disc 33, the frictional engagement between the vertical wall 25 and the standing plate 27, and thus the force at which the displacement begins, can be set very precisely.
- a clamping nut 40 is provided for receiving the fastening means 21, which is attached to the standing plate 27 before assembly.
- a quiver 50 is provided in which the nut 51 of a threaded bolt is inserted or pressed.
- the standing plate 27 can also be attached to the wheel house 6 as well as to the side member 8. What is essential is the frictional connection, which enables a precisely predictable and flush with the front flap to withdraw the dangerous edge 13.
