Definitions

  • the invention relates to a tub for use on internal combustion engines or transmissions according to the preamble of claim 1 and a method for their preparation according to the preamble of claim 6 (see, for example JP-A-55 104 512 ).
  • the metal part is crowned at least in some of the not immediately adjacent to the tub areas, it is achieved that the tub, under line-shaped attachment of fasteners to the spherically shaped areas, against the internal combustion engine or the transmission with the interposition of sealing means is clamped.
  • the linear contact with the fasteners requires that tilting movements of the tub wall relative to the attachment can take place to a certain extent without appreciable bending stresses occurring in the tub wall. By this measure, cracking by high bending stresses in the region of the tub rim can be advantageously avoided.
  • the manufacture of the tub according to the invention for use on internal combustion engines or transmissions is advantageously carried out so that the tub is first preformed in one or more deep-drawing steps of sheet metal. Detached from these operations at least one metal part is produced in a shaping manufacturing process, wherein the metal part is shaped so that its shape corresponds to at least a part of the later course of the edge of the trough.
  • the metal part and the preformed trough are then placed in a die and subjected to a further forming process in which the edge of the Tub is formed around the metal part, such that there is a positive or positive connection between the tub and metal part.
  • the further forming process may advantageously be a further deep-drawing step, but it is also possible to connect the metal part and the tub by crimping the tub rim around the metal part.
  • the production of the metal part for reinforcing the Wannenrades can be done by different shaping methods, the simplest and thus most advantageous is the metal part by bending e.g. a round rod or in a metal casting process.
  • the drawing shows a simplifying partial representation of a step perpendicular to the peripheral edge of a tub, in the example of an oil pan for the internal combustion engine of a commercial vehicle.
  • a metal part 2 in the example a round bar molded positively.
  • the Wannerand 3 elastic sealant 4 On the side facing away from the metal part 2 side of the tub rim 3 is an encircling with the Wannerand 3 elastic sealant 4, which is at investment of the tub 1 to the crankcase 5 between this and the tub rim 3.
  • an L-shaped claw 6 is provided, the tangential with their first leg 6a, seen in the image plane but in a linear manner, rests against the metal part 2.
  • the attachment of the claw 6 on the crankcase 5 by means of a through-bolt 7, which projects through the second leg 6 a and by means of a threaded bore (not shown) is anchored in the crankcase 5.
  • the molded metal part for. also be made of cast iron or cast aluminum. Which material is used depends on the respective design conditions.
  • the tub 1 is made in several deep-drawing steps of sheet metal, by first the tub 1 itself is preformed in several steps. Deep-drawing of sheet metal are well known to those skilled in the art, so that a detailed description is unnecessary. Detached from these operations, the metal part 2 is produced in a subsequent manufacturing process. For the oil sump described above, this means that the round steel is bent so that it corresponds to the later tub rim 3. The metal part 2 and the preformed trough 1 are then placed in a die, so that both are fixed to each other. In a further forming process, the tub rim 3 is then formed around the fixed metal part 2, such that, as shown in the figure, a frictional or positive connection between the tub 1 and the metal part 2 results. The further forming process can be a further deep-drawing step, but it is also possible. Metal part 2 and trough 1 by crimping the tub rim 3 to connect the metal part 2.
