Definitions

  • the invention relates to an assembly for an intake tract of an internal combustion engine, in particular for an air filter, and an air filter with at least one such assembly.
  • the invention further relates to a method for fastening two tubular bodies of the assembly together.
  • Tubular bodies typically made of plastic, serve as an air duct between an air intake opening and an internal combustion engine.
  • the tubular body preferably forms an intake passage to the filter housing.
  • Such tubular body can be mounted with one of its two end-side openings on the filter housing, for which purpose a complementary formed to the mounting portion of the tubular body counterpart can be provided on this.
  • Such an air duct is for example from the DE 20 2006 012 636 U1 known.
  • Said air duct can be connected by means of a snap connection with a filter housing.
  • the air duct and the filter housing are put together along a mounting direction and fixed together by means of a latching connection.
  • the respective end faces of air duct and filter housing extend at right angles to the mounting direction, so that the two components meet each other surface.
  • the so-called corrugated pipe section of the air duct must be compressed in order to put the mounting sections of air duct and filter housing into one another.
  • this process proves to be time-consuming and in practice often requires the use of several workers.
  • the basic idea of the invention is accordingly to make the opening-side end faces of two interconnected tubular bodies of an assembly oblique with respect to their respective longitudinal direction. In this way, an undesirable lateral collision of the two components to be fastened to each other can be avoided if they are initially aligned transversely to the actual mounting direction each other, because the two tubular body according to the invention with oblique front sides touch only shortly before reaching the final assembly position.
  • the orientation of the two tubular bodies to each other transversely to the actual mounting direction is much easier to accomplish in the presented here tubular bodies with oblique front side than in conventional tubular bodies with right-angled end faces.
  • a reversibly compressible line section is provided in one of the tubular body, which causes a longitudinally directed displacement of at least one of the end faces by acting transversely to the longitudinal direction of assembly forces.
  • the compressible line section may be formed by an elastic material, in particular an elastomer tube, or by a telescopically movable structure.
  • the remaining mounting path along the mounting direction can be realized in an advantageous embodiment of the invention by axial expansion of a bellows, which can be integrated in said tubular body.
  • An assembly according to the invention comprises a first tubular body extending along a first longitudinal direction and having on a first end face a first opening for fastening the first tubular body to a second tubular body.
  • the assembly further includes a second tubular body extending along a second longitudinal direction and having a second end for attaching the second tubular body to the first tubular body at a second end face.
  • the first end side of the first tubular body is arranged in a longitudinal section along the first longitudinal direction obliquely to the first longitudinal direction.
  • the second end face of the second tubular body is arranged in a longitudinal section along the second longitudinal direction obliquely to the second longitudinal direction.
  • the longitudinal directions of the two tubular bodies can each be defined by a main flow direction of the air flowing through the tubular body. In an attached state of the two tubular body, the two longitudinal directions are substantially parallel to each other, and the end faces of the two tubular bodies are arranged in the longitudinal section along the longitudinal directions substantially parallel to each other.
  • substantially herein is meant that also embodiments are included, which may differ slightly from an exactly parallel orientation, as long as this does not interfere with the assembly, so in particular the insertion or insertion of a tubular body in or on the other tubular bodies.
  • deviations from the exactly parallel orientation of the two tubular bodies are up to 2 °, particularly preferably up to 1 °, most preferably up to 0.5 °.
  • the end faces of the tubular body according to the invention can also extend at an angle to each other.
  • the mounting direction arranged below the front side has a slope with a larger angle.
  • the front side in the mounting direction has a bevel with a smaller angle.
  • an overlap area is formed between the end faces, which is larger in the lower area than in the upper area.
  • the acute angle is at most 45 °, preferably less than 30 °, more preferably between 5 ° and 15 °.
  • Such a geometry supports a particularly simple assembly of the tubular body.
  • the second tubular body can be inserted into the first tubular body or can be plugged onto it, or vice versa. This allows a simple way airtight, yet releasable attachment of the two tubular body of the assembly together.
  • Said insertion process of the second tubular body in the first tubular body can be further facilitated if formed in an advantageous development of a peripheral wall of the second tubular body in the region of its frontal opening a circumferentially extending, outwardly projecting web.
  • This web acts for the inserted into the first tubular body second tubular body as a stop for the insertion movement along the first longitudinal direction.
  • Said bridge can completely or partially circulate in the circumferential direction. Instead of a web and the formation of a projection is conceivable which projects radially outward from the peripheral wall.
  • the first tubular body in the longitudinal section along its first longitudinal direction on an upper body wall is shorter than a wall length of the upper body wall opposite lower body wall, or vice versa.
  • the second tubular body has an upper body wall in the longitudinal section along its second longitudinal direction. The wall length of this upper body wall is longer than a wall length of a lower body wall opposite the upper body wall, or vice versa.
  • the two wall lengths of the first tubular body with respect to a virtual first reference plane are measured transversely to the first longitudinal direction.
  • the two wall lengths of the second tubular body are measured transversely to the second longitudinal direction with respect to a virtual second reference plane.
  • a sum of the wall length of the upper body wall of the first tubular body and the wall length of the upper body wall of the second tubular body is equal to the sum of the wall length of the lower body wall of the first tubular body and the wall length of the lower body wall of the second tubular body.
  • a bellows-like trained longitudinal portion in another preferred embodiment may be provided in the second tubular body, with respect to its longitudinal direction at a distance from the opening a bellows-like trained longitudinal portion.
  • This is preferably designed such that a length of the second tubular body along its second longitudinal direction is variable up to a predetermined variation length.
  • This property of the tubular body facilitates the insertion / pushing or plugging / plugging of one tube body in the other tube body by maximum expansion of the bellows-like longitudinal portion in the longitudinal direction, after the two tube bodies have previously been arranged in alignment with each other by a movement transverse to the longitudinal direction.
  • the bellows-like trained longitudinal section can be compressed when merging the two tubular body and only after the two tubular body are arranged in alignment, be extended again in the longitudinal direction to effect a connection between the two tubular bodies.
  • the first end face of the first tubular body in the longitudinal section along the first longitudinal direction forms a first angle between 90 ° and 180 ° with the first longitudinal direction.
  • Preferred angle values for the first angle are between 100 ° to 150 °, particularly preferably about 120 °.
  • the second end face of the second tubular body forms a second angle between 90 ° and 180 ° with the second longitudinal direction.
  • Preferred angle values for the second angle are between 100 ° to 150 °, particularly preferably about 120 °.
  • the second angle may be greater than the first angle, whereby an overlap area between in the upper region is smaller than in the lower region. In this way, a particularly reliable recording is formed.
  • a mechanically stable, yet easy to be solved attachment of the two tubular body to each other can be achieved in a further preferred embodiment, in which a latching connection or snap connection is formed on the two tubular bodies.
  • Said latching connection or snap connection can comprise at least one latching element, preferably in the manner of a projection, on one of the two tubular bodies and a recess complementary thereto, in particular a passage opening.
  • a guide structure for guiding the respective other tubular body is formed on the inside or outside of a tube wall of the first and / or second tubular body in the region of the first or second opening. This facilitates in particular the insertion or plugging of a pipe body into or onto the other pipe body.
  • the sealing device may comprise one or more suitably designed sealing rings, preferably in the form of O-rings of a rubber-elastic material, particularly preferably of an elastomer.
  • the assembly is to be used as part of an air filter, it is proposed in a particularly preferred embodiment of the invention to form the first tubular body as a fastening nozzle of a filter housing, from which the first tubular body, ie away from the housing housing bounded by the filter housing, projects away from the outside.
