Definitions

  • the invention relates to a soundproofed sheet metal oil pan for internal combustion engines according to the generic term.
  • a source of sound emission is usually an insufficiently soundproofed oil pan.
  • To improve the structure-borne sound insulation it is known to design the oil pan in two or more layers, or to reduce the sound emission of this oil pan by using plastic as the material for the oil pan. In order to prevent sound bridges between the crankcase and the oil pan, it is known to insert elastomers between the two parts.
  • the object of the invention is to significantly reduce the structure-borne noise from tanks.
  • the structure-borne noise is noticeably reduced by the over-head with reasonable effort.
  • Engines with less body noise can be retrofitted in a relatively simple and inexpensive manner.
  • the over-tray can be designed in two or more layers in sheet steel.
  • the overflow trough can be made of multi-layer steel sheet or also of one layer in plastic.
  • Multi-layer steel sheet results in a high noise level and is also inexpensive.
  • the plastic design gives good sound insulation through internal damping of the material even in one layer.
  • FIG. 1 shows a tank 1, which closes a crankcase 2 at the bottom.
  • the oil pan 1 is fastened to a peripheral flange 4 of the crankcase 2 by means of screws 3.
  • the bath 1 is approximately surrounded by a bath 7, which can either be made of plastic or sheet steel in deep-drawing quality. Depending on the requirements for sound insulation, the steel sheet can be designed as one or two or more layers.
  • the overpan 7 is connected at all points of contact with the oil pan 1 or the crankcase 2 by means of elastomeric elements decoupled from structure-borne noise.
  • an l-shaped profile 8 is provided on the upper edge of the bath 7, into which a first elastomeric element 9, which is open at the top, is inserted.
  • the trough 7 is opposite a flywheel housing 10 as one Part of the crankcase 2 is sealed against sound leakage via a second elastomeric element 11.
  • the second elastomeric element 11 is open on one side and is pushed over the edge of the trough 7 and pressed against the flywheel housing 10.
  • the ⁇ lwanne 1 has a drain screw 12 at its lowest point.
  • the drain plug 12 or its threaded part 13 is sealed against the overflow tub 7 by means of a third elastomeric element 14 to prevent sound from escaping.
  • FIG. 2 A cross section II-II through the oil pan 1 is shown in FIG. 2.
  • the oil pan 1 is pressed against the flange 4 of the crankcase 2 with the interposition of a seal 1a by means of the screws 3.
  • the bath 1 is surrounded by the bath 7.
  • the flange of the tank 1 is surrounded on the outside.
  • a leg 1b engages from above into the first elastomeric element 9, which is open at the top.
  • Further elements of the oil pan 1, such as the drain plug 12, a connector 15 for the filling and sheet metal spheres 16, which serve as a support for the engine, are made at the contact points by additional elastomeric elements to the water pan 7 against sound leakage sealed. Details about the formation of these elastomeric connecting elements are shown in the following figures.
  • FIG. 7 A connection of the oil bath 1 and the water bath 7 in a plastic design is shown in FIG.
  • the tub 7 has retaining lugs 17, the tub 1 has under the screws 3 used to fasten the tub 7 specially shaped underlays 18 and both parts are non-positively connected by spring wire brackets 19.
  • the first elastomeric element 9 seals against airborne noise and decouples it from structure-borne noise.
  • FIG. 4 shows in detail the sound seal of the opening for the drain plug 12.
  • the drain plug 12 is screwed into a threaded part 13, which ⁇ ldicht in the ⁇ l tub 1 is inserted.
  • the connection of the threaded part 13 to the trough 7 takes place by means of the third elastomeric element 14, which is sealed against the threaded part 13 by an annular sealing lip 20 against the escape of airborne sound.
  • Sealing against the overflow trough 7 takes place by means of an annular groove 21 which sealingly encompasses a bore in the overflow trough 7.
  • FIG. 5 shows in detail the sound seal of the sheet metal cap 16, which is connected to the tank 1 by spot welding or the like.
  • a fourth elastomeric element 22 is provided for sealing, which is almost identical in construction to the third elastomeric element 14, which is why it should not be explained in more detail.
  • FIG. 6 shows the sound seal of the connector 15, which is used for filling.
  • the nozzle 15 is sealed at its upper end with a fifth elastomeric element 23 against the overflow 7.
  • This elastomeric element 23 is similar to the elastomeric elements 14 and 22.
  • the connector 15 is screwed into the oil pan 1 into the threaded insert 24 in an ⁇ tight manner.
  • the connection piece for the measuring tube in the oil trough and its soundproofing against the overflow trough 7 are also fixed analogously.
  • FIG. 8 A detail of the profile bridge 6 according to a section VII-VII from FIG. 8 is shown in FIG. Since in the area of the vibration damper 5 the upper edge of the oil pan 1 cannot be shaped in a u-shape, so that the leg 1b is omitted here, the profile bridge is used for evenly pressing the seal 1a (FIG. 2) 6 is provided, which has the necessary bending stiffness in order to distribute the contact pressure of the screws 3 evenly as a line load over the end face of the oil seal.
  • a u-shaped profile 25 is provided on the upper side thereof in order to accommodate the first elastomeric element 9.
  • the profile bridge 6 has a nose 26 into which the first elastomeric element 9, which is open at the top, is inserted. As a result, air-tightness is achieved in this area between the tank 1 and the tank 7.
  • FIG. 7 The area shown in section in FIG. 7 is shown in plan view in FIG.
  • FIG. 9 shows in detail the sound seal of the trough 7 against the flywheel housing 10.
  • the trough 7 is open in the direction of the flywheel housing 10 and ends here in a web 7a. This is sealed against the flywheel housing 10 by the second elastomeric element 11.
  • this second elastomeric element 11 is angled in the region of the oil pan flange and ends on the right and left side in the mirror-image-shaped two legs 29 which rest on the right and left side of the oil pan flange of the crankcase ⁇ uses 2 facing web sections 30 of the] tub 7 are attached.
  • the two legs 29 each have an extension resting on a support surface 31 (FIG.
  • FIG. 11 shows the connection between the overflow tub 7 and the overflow tub 1. Since the overflow trough 7 is made of sheet steel in the example shown, it is essential to ensure acoustic decoupling.
  • the connection is made by spring wire brackets 19. These spring wire brackets 19 are connected to at least one contact point (here with the oil pan 1) with the interposition of a sixth elastomeric element 32. The other end can be connected directly to a nose 33, which is connected to the overflow tub 7. Alternatively, the element 32 can also rest on a special screw support 18 according to FIG. 3.
  • FIG. 12 shows the same detail as shown in FIG. 10, but with reference to a design in the steel sheet.
