Definitions

  • the invention relates to an oil pan for internal combustion engines, which below the Crankshaft area of the engine is arranged.
  • oil sumps are mainly made from welded sheet steel or by metal casting.
  • Oil pans made from thermoset or rubber (DE 832 3945 U1) are also known.
  • the automotive industry has long attempted to keep the weight of the vehicles as low as possible.
  • One of the disadvantages of the oil sumps is that they make a significant contribution to noise emissions.
  • an oil pan is already known (DE 31 42327 A1) which is double-walled and consists of an inner and outer shell, the inner shell being fastened to the crankcase and the outer shell being fastened to the upper part of the inner shell with the interposition of an elastic element is. This is designed as a ring profile and vulcanized between the two shells and its name is tuned in terms of vibration to the overall system.
  • This is intended to decouple the outer shell from the vibration system of the inner shell.
  • the area between the inner and the outer shell serves for the targeted guidance of a coolant, as a result of spiraling, elastic ribs, which at the same time keep the two shells at a distance. Since the elastic element is vulcanized in, the two shells must be made of a metallic material. A major disadvantage of this oil pan is that it is complicated in its construction, requires a lot of production and has a relatively high weight.
  • the invention had for its object to provide an oil pan that is small Has weight, is inexpensive to manufacture, high load capacity and rigidity and has low noise emissions.
  • the oil pan consists of an inner shell and an outer shell, which however only surrounds the lower area including the bottom of the inner shell. Ribs are arranged between the two shells, by means of which the distance between the two shells is defined.
  • the ribs can be designed in various ways, for example as continuous longitudinal or transverse ribs with and without interruption. The height of the ribs and the spacing of the individual ribs from one another is determined by the local state of stress. The arrangement and design of the ribs should ensure an optimal bending stress condition.
  • the ribs also contribute to the required rigidity and stability of the oil pan.
  • the two shells are preferably connected by welding, the joining process taking place in the area of the ribs.
  • the ribs can be molded onto both the outer shell and the inner shell.
  • the two shells are made of thermoplastic by injection molding as separate components and then connected to each other by gluing, welding or foaming. It is also possible to connect the two shells to one another using a suitable snap connection. From the point of view of tool technology, it is advisable to also form the ribs on the inner shell.
  • the production of the two shells using the injection molding process and the subsequent joining process by welding ensure a very efficient, cost-effective production of the oil pan. In comparison to oil pans made of metallic materials, a weight reduction of approx. 50% can be achieved at the same time.
  • the outer shell can also be formed from several components that are connected to the inner shell.
  • the areas in which the oil drain plug and the sensor are arranged can be single-walled, since wall thickening or stiffening is already present in these areas due to the threaded connector.
  • the production of the shells or shell parts using the injection molding process also makes it possible to equip the shells with further functional elements, such as, for example, a cable duct or lockable pockets for accessories.
  • noise emissions are also considerably reduced.
  • the outer shell and the air chamber system located between the outer shell and the inner shell make a significant contribution to this.
  • the bottom outer shell also has a protective function against mechanical influences from the outside.
  • the oil pan shown in FIG. 1 is fastened to the flange of the crankcase (not shown in more detail) of the internal combustion engine by means of fastening screws which are guided through the openings 15, a seal 16 being arranged between the flange and the oil pan.
  • the oil pan consists of an inner shell 1 and an outer shell 2, which are produced as separate components from a thermoplastic material in an injection molding process.
  • the outer shell 2 is arranged only in the lower region of the oil pan, the inner shell 1 being set back a little in this region, such that the outer shell 2 fastened to the inner shell 1 is flush with the inner shell 1 at the transition points 3.
  • Ribs 4 are arranged between the inner shell 1 and the outer shell 2, which define the distance between the two shells.
  • the distance between the ribs 4 and the height of the ribs 4 is determined by the local state of tension of the oil pan.
  • the ribs 4 are molded onto the inner shell 1.
  • the connection between the inner shell 1 and the outer shell 2 takes place, in each case at the contact surface between the ribs 4 and the outer shell 2, by welding, such as, for example, heating element welding, ultrasonic welding or friction welding.
  • the welds formed are marked with position 5.
  • the required openings 6, 7 and 8 for the oil drain plug (opening 6), the sensor for checking the oil level (opening 7) and for the closure element for the oil filler neck (opening 8) (Fig. 2) are formed during the injection molding .
  • a circumferential bead 14 is formed on the end of the oil filler neck 13 pointing outwards, which bead serves as an axial securing aid for the oil filler hose (FIG. 2).
  • a channel 9 for cable guides is provided, which is formed by the two projecting side walls 10, 11 and the cover 12 that can be fitted.
