Definitions

  • the present invention relates to a stiffening element and stiffening system for securing a plastic container and for stabilizing the connection of the engine block and the transmission housing in motor vehicles.
  • containers such as engine oil pans or gear oil pans are liquid-tightly integrated with the engine block as follows: a flange is formed along the edge of the opening of the corresponding container, this flange comprises bores or through holes into which metal bushings are inserted; in turn, screws are screwed for screwing the container to the counterpart. Between the top of the flange and the counterpart a seal is arranged.
  • the plastic material of the container is heavily loaded after application due to the forces acting in the region of the sleeve, so that many screwing points are necessary to achieve the liquid tightness.
  • the rigidity of the construction depends on the modulus of elasticity (modulus of elasticity) of the material used and also to a considerable extent on the operating or service temperature.
  • hydride containers made of plastic with integrated sheet metal carriers have the disadvantage that, due to the different coefficients of thermal expansion of the materials, there can be severe distortion and thus leaks and thus failure of the component. This problem occurs naturally in such devices increasingly, such. As in oil pans, where the temperature can vary greatly.
  • a metal oil pan e.g., die-cast aluminum
  • the disadvantage here is the higher weight of the metal oil pan and, above all, that such a metal oil pan radiates the engine noise much stronger.
  • a stiffening element having the features of the preamble of independent claim 1 is known from EP-A-811761.
  • a stiffening element 1 for fastening a plastic container and stabilizing the connection of the engine block on the one hand and transmission housing on the other hand in motor vehicles, the stiffening element 1 further comprising first vertical walls 2 and mi n least one second vertical wall 4, wherein the second vertical Wall 4, the first vertical walls 2 connects to each other, wherein the first vertical walls 2 and the at least one second vertical wall 4 fastening points 3, 5 and wherein the axes or their parallels of the first attachment points 3 of the first walls 2 substantially perpendicular to the axis or their parallels of the second attachment points 5 of the second wall are 4, wherein at least the first vertical walls 2 and the first attachment points 3 are used for attachment of the plastic container.
  • the upper edge of the first vertical walls 2 of the stiffening element at the lower edge 8 of the flange of the plastic container 6 fits accurately and positively. Furthermore, the attachment points 3 protrude beyond the upper edge of the first vertical walls 2 and are inserted in the installed state in recesses 9 of the flange 8 of the plastic container 6.
  • the attachment points are sockets.
  • the bushings need not be in a completely regular, cylindrical and closed shape, but may also have, for example, a gap, or partially open laterally, which occurs especially when the stiffening element including the bushes is cut and bent from a piece of sheet metal.
  • a stiffening element comprising first vertical walls 2 with attachment points 3 whose longitudinal axis is parallel to the plane of the vertical first walls.
  • the fastening means which are guided by the attachment points 3, bushings, are fastened to the underside of the engine block.
  • the stiffening element furthermore comprises at least one second vertical wall 4, which connects the first walls 2.
  • two opposing vertical first walls 2 are connected to each other via a second vertical wall 4.
  • the term "connected” is not intended to be understood as meaning that the stiffening element must be assembled from a number of independent parts, because a stiffening element made in one piece (e.g., by die-casting aluminum) is also encompassed by the present invention.
  • the stiffening element is preferably substantially U-shaped. In alternative embodiments, the stiffening element may also be e.g. cover the entire circumference of the oil pan to be fastened.
  • the at least one second wall 4 of the stiffening element has second attachment points 5.
  • the gearbox is to a certain extent lower than the engine block.
  • the fastening means, which are guided by the second attachment points 5, bushings, are fastened to the side of the transmission housing.
  • the axes or their parallels of the first attachment points 3 of the first walls 2 are substantially perpendicular to the axis or their parallels of the second attachment points 5 of the second wall 4, i. the plane in which the former axes extend is substantially perpendicular to the plane in which the latter axes extend.
  • the advantage of the stiffening element according to the invention is that the oil pan is completely decoupled from the force flows. So it is even possible to attach a lighter oil sump made of plastic over the stiffening element.
  • the advantage of this is that a plastic sump transmits much less the noise from the engine and radiates, resulting in a reduction of noise pollution.
  • the plastic container is fastened by the stiffening element.
  • This attachment of the plastic container e.g. an oil pan to the engine block, preferably by screwing, wherein the screws or bolts are inserted into the attachment points, sockets, and bolted in the counterpart.
  • the stiffening element has the advantage here that the forces emanating from the screw connection points (bushes) are distributed uniformly over the entire flange of the plastic container during or after the screwing over the first vertical walls. As a result, individual areas of the plastic part are subjected to less stress and the number of Verschraubungsconce can be reduced without problems with the tightness occur.
  • the present invention enables the separation of the two main functions of the oil sump (i) media guide; ii) stabilization).
  • the oil sump can be optimally designed with regard to its function of the oil guide: Since the sump is completely decoupled from the power flows, the design as a plastic sump is possible, which leads to the reduction of noise.

  • the stiffening element is made of metal, preferably of steel, or of a cast metal, preferably cast iron, die-cast aluminum or magnesium casting. In an alternative embodiment, the stiffening element is made of sheet metal.

  • the first walls 2 are flanged at the edges or have an L-shaped cross-section.
  • the bearing surface of the vertical first walls is increased at the bottom of the flange, resulting in a greater distribution of Anschraub mechanism and Anschraubmomente.
  • the second wall 4 may also have a fold.
  • one or more edges of the first and / or second walls may have a fold.

  • Another advantage results from the possibility to use plastic containers (plastic oil pans) per se, resulting in a reduction of noise pollution. Furthermore, there are advantages from the smaller number the screw points due to the better acoustic decoupling.
