Definitions
- the invention relates to a motor vehicle according to the preamble of claim 1, a motor vehicle according to the preamble of claim 3 and a water tank for a motor vehicle according to claim 9.
- From DE 699 10 529 T2 discloses a motor vehicle of the type discussed here, which has a front cover for covering a unit space, below which a water tank is arranged. This has a serving as a support / support for the front hood wall, which is provided at its free end with a seal against which the bonnet sealingly engages in the closed state.
- the extending in the vehicle transverse direction and in the vertical direction to the front roof flat side wall has a defined starting point for a compliance in a caused by deformation of the front hood as a result of an impact of a person force, wherein the starting point is formed by a crank ( Figure 5).
- the crank ensures that, in the event of a frontal pressure load on the wall, for example in the event of a head impact of a pedestrian on the front hood with deformation of the same in the direction of the underlying unit space, the wall can deflect by bending in order to reduce the risk of injury.
- the bending of the wall which takes place by design directly when pressurizing the wall, to facilitate a subsequent compression of the wall.
- the compression leads to a shortening of the wall with simultaneous Quer4.000svergr ⁇ ß réelle same.
- a motor vehicle with an impact-damping hood is known, which is provided on its an aggregate space facing bottom with a stiffening structure, which is designed so that the hood is partially different stiff.
- the stiffening structure of predetermined buckling lines is formed with the object of the so weakened bows is that Bonnet to soften in itself. Due to this configuration, however, the risk of accidental damage to the hood, for example, when supporting a fitter during maintenance work, significantly increased.
- a motor vehicle with the features of claim 1 is proposed.
- This is characterized in that the flexibility of the wall provided below the front hood arranged in the closed position, which is oriented perpendicular or in the vertical direction to the front hood flat side, is realized by means of at least one predetermined bending point and / or predetermined breaking point formed by at least one partial wall thickness reduction is.
- the wall is kinked, wherein the buckling in its continuation may possibly lead to a fracture of the wall.
- a “buckling” is then present or is given when the over the vehicle front hood pressure force applied wall suddenly deflects laterally, which can occur before reaching the squeeze limit.
- the wall In order for the wall to be able to buckle under load and not simply be compressed, it must in particular have a certain length.
- the decisive for the buckling ability or buckling properties of a component parameters are well known in the art, for example, from “Engineering Mechanics, Part 3 Strength of" Holzmann / Meyer / Schumpich, BG Teubner Stuttgart 1990,
- the buckling of the wall takes place only when the force acting on the end face of the wall, caused for example by a head impact of a person on the front hood with deformation thereof in the direction of the wall, exceeds a certain adjustable by appropriate design of the wall thickness reduction limit.
- the embodiment of the invention is distinguished from known constructions by increased stability, which moreover ensures that during assembly of the motor vehicle and maintenance work in the unit room, the wall not already at a low force, for example, by supporting a person or dropping a component inadvertently is damaged.
- inventive design of the defined bendable wall which forms a kind of abruptly resilient abutment for the bonnet, a particularly rigid or a stiffer front hood with a high stability can be used, without this - if any- to an undesirably high significant reduction of Pedestrian protection at head impact leads.
- the arranged below the front cover wall which is perpendicular or perpendicular to the front hood flat side, can run within the unit space in virtually any direction, so for example in the vehicle transverse direction or vehicle longitudinal direction, with each intermediate position can be readily realized without the function of the invention to affect the wall when Druckkraftbeetzschlagung.
- a motor vehicle with the features of claim 3 which is characterized in that the crank, which ensures a desired compliance of the wall at a caused by deformation of the front hood as a result of an impact of a person force, not on the Wall itself is formed, as in the known motor vehicle, but on a running in the direction perpendicular to the wall wall portion.
- the wall is connected to a running in the direction perpendicular to this wall portion, which is supported only in a lying outside the direction of action of the force exerted on the wall area by means of an abutment.
- the resilience of the wall is thus achieved by the possibility of evading / deflecting the same in the direction of the roadway, so that the wall itself can be made rigid.

- the water tank 11 has a in this embodiment made of sheet metal first part 13, in particular housing part, of which in the illustration of Figure 1, only one perpendicular to an imaginary horizontal wall 15 with formed on the front hood free end flange 17 can be seen.
- the second water box part 19 forms a cover for the water tank 11 and the first water box part 13 and has a first, substantially parallel to the bonnet flat side extending bottom wall 21, at its one edge region on the windscreen 7 and at its opposite edge region with the first water box part 13th concludes.
- the second water box part 19 has a wall 27 extending in the vehicle transverse direction and substantially perpendicular to the front hood flat side, at the end of which a seal 29 is provided, which sealingly abuts against its inner surface 31 when the bonnet 3 is closed.
- the seal 29 may be formed as a separate part and attached to the wall 27 or in otherwise attached to it. Alternatively, it is possible to inject the seal 29 against the wall 27.
- the second water box part 19 has in the transition region between the bottom wall 21 and the wall 27 still a wall portion 33 which rests in the assembled state on the flange 17 of the first water box part 13 and is preferably attached thereto.
- the wall portion 33 only a partial overlap with the underlying flange 17, that is so in the vertical direction is not supported in sections, which will be discussed in more detail below.
- FIG. 2A shows a section of the second water box part 19 in the region of the wall 27 in a mirrored view.
- the seal 29 is not shown.
