Definitions

  • the invention relates to an oil pan, in particular for an internal combustion engine, according to the preamble of claim 1.
  • Such oil pans which are arranged on the underside of an internal combustion engine, must be made stable for receiving high forces in order to withstand high mechanical influences, which may occur, for example, when a rockfall or a touchdown of the vehicle on the ground.
  • oil pans made of metal or even, as in the EP 1 041 253 A1 described as a one-piece injection molded part made of polyamide or polypropylene.
  • a drain opening is introduced into the tub bottom, which is closed by an adjustable closure element.
  • this closure element can be designed as an oil drain plug, which is screwed through a copper seal in the discharge opening under pressure, whereby the tightness is produced.
  • the invention has for its object to provide an oil pan with a simply constructed Ablass 2015, which is also suitable for use in relatively thin-walled oil pans or oil sumps made of plastic.
  • the discharge device comprises an adjustable valve body which is to be adjusted between a closing position sealing the discharge opening in the wall of the oil sump and an opening position releasing the discharge opening.
  • the discharge device On the valve body the discharge device is a sealing element made of resilient material, which closes the discharge opening in the closed position. Furthermore, it is provided that the valve body is fixed in its closed position by means of a closing element on the wall of the oil pan and the closing element holds the valve body held on the sealing element in the closed position, wherein the closing element may be formed separately from the valve body.
  • This embodiment has the advantage that no thread is required in the wall of the sump which delimits the drain opening, so that both very thin-walled oil sumps of metal and plastic sumps can be used. Dispensing with a thread in the drain opening constitutes a constructive feature a considerable simplification.
  • valve body during the transfer movement between its closed and its open position exerts an axial lifting movement, which is combined with a rotary movement, where appropriate the transfer between the closed and open position of the valve body by means of simple adjusting elements is feasible and in particular from outside the oil pan can be performed.
  • the valve body can be moved from an external component, such as a tool, manually - possibly also by means of an actuator - in the open position, whereby the drain opening is opened and the oil can escape from the tub.
  • To open the discharge opening of the valve body is raised including the sealing element disposed thereon from the sealing position.
  • the opening movement of the valve body is advantageously a lifting movement, which is superimposed on a rotational movement.
  • the closing element via which the valve body is fixed in the closed position on the wall of the oil pan, can, for example, as a projection be formed of the wall of the oil pan, which protrudes into a slide track on the valve body.
  • the slide track expediently comprises a horizontal section and an obliquely extending section with a component in the direction of the longitudinal axis of the valve body.
  • the horizontal portion corresponds to the locking position of the valve body in its sealing or closing position, whereas the inclined portion generates the lifting movement of the valve body in the axial direction.
  • the slideway sections running transversely to the lifting movement can also be combined with a roughened surface structure in the walls delimiting the slide track in order to improve the self-locking effect.
  • the illustrated in Fig. 1 oil pan 1 for an internal combustion engine of a motor vehicle has an existing plastic oil wall housing 2, which is produced in particular by injection molding.
  • the outer wall 3 of the oil pan housing 2 comprises a lower trough bottom 3a and circumferential side walls 3b.
  • the tank bottom 3a and the side walls 3b lying in the vehicle forward direction F are enclosed by a protective wall or shell 4, which is designed as a separate component and is connected to the tank bottom 3a or the front side wall 3b via spacer elements 5.
  • the spacer elements 5 ensure that the protective cover 4 is at a distance from the outer wall 3 of the oil pan housing 2, so that between the outer wall 3 and protective cover 4, a gap is formed.
  • the protective cover 4 is expediently also made of plastic, as well as the spacer elements 5.
  • the protective cover 4 including the spacer elements 5 are molded onto the outer wall 3 of the oil pan.
  • the protective cover 4 is concentric with the outer wall 3 of the oil pan. Due to the distance between the protective cover 4 and the outer wall 3 is in the case of a rockfall or as shown in Fig. 1 uneven placement of the oil pan on a sloping bottom ensures that initially only the outer protective cover 4 is damaged, whereas the outer wall 3 of the oil pan remains undamaged.
  • Ribs 7 may be formed, which reinforce the outer wall and provide additional stability. These Ribs 7 are arranged both in the region of the side walls 3b and expediently in the region of the trough bottom 3a directly on the outer wall 3.
  • the protective cover 4 forms part of an underbody cover 9, which is provided on the underside of the motor vehicle.
  • the protective cover 4 surrounds the front side wall 3b, also the bottom 3a of the outer wall 3 of the oil pan is embraced.
  • the protective cover 4 is at a distance from the outer wall 3, wherein a damping element 8 is introduced into the intermediate space between the outer wall 3 and the protective cover 4.
  • the damping element 8 consists in particular of an elastomer and is firmly connected to the protective cover 4.
  • the underbody cover 9 held on the vehicle, including the protective cover 4 forming the front region of the underbody cover, is expediently not connected directly to the oil sump 1, but is held on a further component of the motor vehicle and becomes a fixed relative position relative to the outer wall 3 of the oil sump 1 due to its inherent stability held.
  • the damping element 8 has expediently no direct connection to the outer wall 3 of the oil pan.
  • damping element 8 it may also be advantageous to connect the damping element 8 to the outer wall 3, for example, to adhere.
  • the protective cover 4 is designed as a separate, separate component which is directly connected to the outer wall 3 of the oil pan 1.
  • spacer elements 5 may be provided, which, however, as shown in the embodiment of FIG. 3, the distance between the protective cover 4 and outer wall 3 does not completely bridge and thus not completely penetrate the damping element 8, but only protrude into the damping element.
  • the spacers 5 are alternately arranged on the protective cover 4 and the tub bottom 3a and the front side wall 3b of the outer wall.
  • connection of the protective cover 4 to the oil pan 1 takes place in this embodiment, exclusively on the damping element 8, which is suitably adhered to the outer wall 3 of the oil pan.
  • the spacer elements 5, which do not completely penetrate the damping element 8, have the task of receiving additional support forces only in the case of a strong external action on the protective cover 4 in the direction of the oil pan 1 and a compression of the damping element 8 as a result, as soon as the protective cover 4 is so is approached far to the outer wall, that the spacer elements 5 abut the respective opposite component.
  • additional spacer elements may be provided which connect the protective cover 4 directly to the outer wall 3 of the oil pan.
  • the discharge device 10 comprises a valve body 11 which can perform an opening and closing movement for opening and closing the discharge port 13.
  • the valve body 11 is in the position shown in Fig. 4 in its sealing or closing position.
  • a sealing element 12 made of soft, resilient material is arranged, which closes the discharge opening 13 sealingly in the closed position of the valve body 11.
  • the valve body 11 is held in the embodiment of FIGS. 4 and 5 by means of a closing element in the sealing position.
  • the closing element consists of a slide track 34, which is introduced into the outer casing of the valve body 11, and a projection 35 which engages in the slide track 34 and is part of the wall of the tub floor. This projection 35 extends in the discharge opening 13 radially inwardly.
  • the slide track 34 includes a horizontally extending Section 34a, which also represents the locking position of the valve body 11 in its sealing or closed position, and a sloping portion 34b, which deviates from the horizontal portion and is associated with the lifting movement of the valve body.
  • the sealing element 12 is formed in the embodiment of FIG. 4 as a sealing ring which is arranged between the outside of the trough bottom 3b and a fixedly connected to the valve body 11 head 33. In the locking or sealing position of the valve body 11, the sealing ring 12 is clamped between the head 33 and the outside of the trough bottom 3b.
  • the sealing ring 12 Due to the horizontally extending portion 34a, the sealing ring 12 is not compressed any further during further rotation of the valve body 11 beyond the required end position. Thus, the sealing ring 12 is not exposed to excessive loads, which could lead to damage.
  • the lower, horizontally extending section 34a of the slide track 34 is bounded by a wall into which a roughened surface structure 36 is introduced in order to increase the self-locking. If the projection 35 abuts against this surface structure 36, an increased friction sets in, which counteracts an accidental, unintentional opening of the valve body 11.
  • the discharge device 10 shown in Fig. 6 corresponds in terms of their construction substantially to that of FIG. 4, but with the difference that a total of two sealing rings 12 between the outer wall 3 of the housing and the valve body 11 and the head 33 are provided.
  • a first sealing ring 12 is located axially between a support shoulder on the head 33 and an end face of a cup-shaped protuberance in the outer wall 3.
  • the second sealing ring 12 is placed radially around the lateral surface of the valve body 11 and transmits in the radial direction sealing forces between the valve body 11 and the inside of the cup-shaped protuberance.
  • the outer wall 3 has two opposing projections 35. Each projection 35 engages in another inclined portion 34b.
  • the discharge device 10 has two offset by 180 ° to each other, inclined portions 34b, which open in a common horizontal portion 34a.
  • a further discharge device 10 is shown, whose structure is similar to the discharge means of Fig. 4 and 6.
  • head 33 instead of a hexagonal head of the connected to the valve body 11 head 33 but formed as a handle which is manually operable, so that can be dispensed with the use of a tool for opening and closing the valve body.
  • an opening 33 a is introduced, in which optionally a lever for applying a high torque for the opening and closing of the valve device can be used.
