Definitions
- the invention relates to a split / intake line part, in particular for use in an internal combustion engine.
- a suction line part can represent an independent suction pipe or can also be part of a suction system of an internal combustion engine.
- Known intake pipes are designed as solid whole parts and consist of the actual intake pipes and the connectors for the air supply to the individual working cylinders.
- the intake duct part can be made of metal or plastic.
- the intake line parts are preferably made of plastic.
- DE 40 03 282 describes an intake line part with suction pipes which can be pivoted relative to one another, the connection being retained when pivoting.
- the object of the invention is to provide a suction line part in which the divided suction pipes are connected in a gas-tight manner by means of a connecting element and the assembly and disassembly of the suction pipe elements should be uncomplicated. This object is achieved on the basis of the preamble of the main claim by its characterizing features.
- the suction tubes which are arranged next to one another and are preferably connected to one another and are connected transversely to the flow direction, are connected to one another in a gas-tight manner with an easily mountable connecting element.
- the split suction tubes are pressed against the restoring force of a seal arranged in the connecting surfaces of the suction tubes and are held in the compressed state.
- the connecting element bridges the connecting joint by two hook plates arranged above and below the parts to be connected, which have hooks on one long side and elongated holes on the other long side.
- the two hook plates are connected to one another by means of bolts which are guided through the suction tube parts or are rigidly connected to them.
- the hook plates are arranged so that the long side, which has the elongated holes, bears on the intake manifold part, which is firmly connected to the engine.
- bolts are also arranged which come into engagement with the hooks of the hook plates when the two halves of the intake manifold are joined. With the help of a closing and Clamping device, the hook plates are moved in the longitudinal direction and thus a gas-tight connection of the suction pipe parts is established.
- Fig. 1 is a perspective view of the intake pipe part with the connecting element
- Fig. 2 is a perspective view of the removable intake manifold part with the corresponding parts of the connecting element.
- Fig. 3 is a perspective view of the fixed intake manifold part with the corresponding parts of the connecting element without the upper hook plate.
- Fig. 4 shows a detailed representation of the hook contour
- Fig. 5 shows the locking and tensioning device
- the connecting element comprises two hook plates 1, each with elongated holes 2 and hooks 3 arranged on the long sides, for receiving the bolts 4, and a locking or tensioning device 5.
- the number of elongated holes 2 and hook 3 depends on the design the suction pipe parts 6, 7 to be connected
- the removable suction pipes 7 have on their cut surface a sealing surface 8 on the end face for receiving a seal, and positioning bolts or projections 9 for adjustment and securing against lateral displacement of the suction pipes.
- the hooks 3 on the hook plates 1 can engage behind the bolts 4 on the flange of the removable suction pipe 7 in such a way that the suction pipes 6, 7 are pressed together when the hook plates 1 are displaced longitudinally.
- the hooks 3 have an increasing profile 12, 13 at the beginning, which is matched to the force-compression characteristic of the seal used, so that at the beginning of the closing process the flanges of the suction pipes 6, 7 travel as far as possible in the compression direction is along the hook contour area 12, which has a steep rise and when the pressing position is reached, the greatest possible force is generated along the hook contour area 13.
- At the end of the hook plate movement there is no movement in the pressing direction along the hook contour region 14, so that a tolerance compensation of the position of the bolts 4 on the intake manifold flanges can take place due to the further movement.
- the suction pipes 6, 7 to be connected to each other are provided with bores 10 for receiving the bolts 4, which connect the divided suction pipes to one another by means of the hook plates 1.
- the length of the bolts 4 can be the same or different. It depends on the shape of the suction pipes 6, 7 to be connected. Depending on the space available, an oblique or straight flange must be connected to one another.
- the two hook plates 1 can thus be arranged obliquely or parallel to one another.
- the bolts 4 for receiving the hook plates 1 are formed directly from the suction pipes 6, 7 or are produced from pressed-in parts or sheet metal.
- the mechanical connection of the divided suction pipes is carried out by inserting a seal into the groove 8 in the groove provided and the hook plates 1 being arranged and mounted above and below the divided suction pipes 6, 7 and by bolts 4 passing through the holes 10 are guided between the individual suction pipes 6, 7, adjusted and connected to one another.
- the gas-tight locking takes place with the locking or tensioning device 5.
- the locking or tensioning device 5 is located on the head between the hook plates 1.
- the locking and tensioning device 5 comprises a housing 11 flanged to the suction pipes 6, in which the locking mechanism 15 is located and a recess 16 in the hook plate 1 for actuating the locking and unlocking of the locking and tensioning device.
- a housing 11 for receiving the closing and tensioning device 5 is directly molded onto the corresponding point on the intake manifold 6.
- the housing for receiving the locking and tensioning device 5 is mounted directly between the two hook plates 1 on the suction pipe 6.
- locking mechanism 15 known components such as eccentrics, cross beams, levers or screws can be used as the locking mechanism 15.
- the shape of the housing 11 depends on the type of locking mechanism 15 selected.
- the housing 11 has a circular or oval circumference.
- an eccentric is used as the locking mechanism, the eccentric pin being through the Recess 16 is performed.
- the recess 16 has the shape of an elongated hole and is mounted transversely to the hook plate. Other shapes and arrangements of the recess 16 are also conceivable and depend on the type of the locking mechanism 15.
- the rotary movement of the eccentric 15 mounted in the housing 11 is converted into a linear movement of the hook plates 1 via the eccentric pin, which is mounted in the recess 16, if necessary with the aid of a correspondingly suitable tool.
- the locking takes place by sliding the bolts 4 on an inclined plane 12, 13 in the hook contour 3 when the hook plates 1 are moved in the longitudinal direction.
- the hook plates 1 shift due to a tensile load on the locking and tensioning device 5.
- the two flanges of the suction pipes 6, 7 are pulled together and press the seal together. Unlocking takes place in the opposite direction by releasing the locking or tensioning device 5.
- the invention is not limited to a suction pipe part with 5 suction pipes.
- Hook plate elongated hole, hook, bolt, locking and tensioning device, suction pipe (flow channel), fixed, suction pipe (flow channel), removable, sealing groove, positioning bolt, hole for receiving the bolts, housing for receiving the locking and tensioning device , serves to compensate for tolerances
