Definitions

  • the invention relates to a kit of parts for a welded oil pan of a piston internal combustion engine.
  • An oil pan made of sheet metal as a welded part requires a large number of pre-machined individual parts and a corresponding number of welds.
  • a complex welding device must be used to ensure dimensionally stable production.
  • the production of a foundry model is required for every design variant and every engine type.
  • Cast oil pans have a high weight due to the minimum wall thickness.
  • the known manufacturing processes for oil pans are uneconomical due to high manufacturing costs.
  • This object is achieved with the characterizing features of the first claim.
  • Low production costs are achieved, on the one hand, by the fact that the number of individual parts of the kit of parts to be connected by welding is considerably reduced and, on the other hand, the pre-machining of the weld seam on the longitudinal seams is part of the extruded profiles.
  • extruded profiles Realize wall thicknesses that are based only on the loads occurring during operation, since large minimum wall thicknesses due to manufacturing are not required. This minimizes the cost of materials and the weight of the oil pan.
  • An oil pan 11 for a piston internal combustion engine consists in the longitudinal direction of a group of three extruded profiles made of light metal connected by welding.
  • the group comprises an approximately symmetrical extruded profile for the base 12 and with a longitudinal channel and two sections of an L-shaped extruded profile for the right and left side walls 13, 14.
  • the two end walls of the oil pan 11 are also connected to the group of extruded profiles by welding.
  • At least one end wall 15 consists of a section of the extruded profile for the side walls which is adapted by corresponding reworking.
  • the section of the extruded profile for the base 12 is adapted in the region of the channel for connection to the end wall 15 by appropriate processing.
  • the other end wall can be a special part produced as a casting with integrated connecting devices for additional units.
  • the oil pan 11 With a corresponding cross-sectional shape, it is also possible to design the oil pan 11 as a one-piece, U-shaped extruded profile, which reduces the number of parts and the workload for welding.
