Definitions

  • the present invention relates to a manifold with a motor flange, an outlet flange and manifold tubes connected at one end to the engine flange and at the other end to the outlet flange.
  • the exhaust flange While the engine flange is fixed to the engine block of a motor vehicle, the exhaust flange must be otherwise secured to accommodate the load resting on the exhaust flange. In particular, if further exhaust components are connected to the outlet flange, such as exhaust gas turbocharger or a close-coupled catalyst, the outlet flange must absorb a significant load.
  • a load transfer is basically possible via the manifold pipes on the motor flange. Due to the different thermal expansions of the manifold pipes because of their different lengths but these must be relatively flexible and are therefore less well suited for load transfer. On the other hand, with bulkheads, it is not possible to realize a load transfer via an outer shell.
  • the invention has for its object to solve these problems.
  • the load to be absorbed by the outlet flange can be transferred to the motor flange and thus to the engine block.
  • the load is guided around the manifold pipes in this way.
  • the manifold pipes can be made flexible without restriction by a necessary load bearing. By diversion of the load via a connection between the outlet flange and the motor flange, the design of the manifold pipes can thus also be optimized.
  • connection between the motor flange and outlet flange is preferably designed so that a heat balance movement between the motor flange and the outlet flange is made possible.
  • the thermal expansions usually can not be completely absorbed by the manifold pipes. Therefore, there is a relative movement between the outlet flange and the motor flange when heated. This is made possible by the said formation of the connection.
  • a heat compensation movement can in particular be made possible by the fact that the connection between the motor flange and the outlet flange has a curved shape. Particularly suitable is an S-shape has been found.
  • the motor flange and the outlet flange are manufactured as separate parts and then connected to one another. In this way it is possible to produce the two parts of different material.
  • the motor flange can be preferably made of high-grade, in particular austenitic steel, while the outlet flange of less high-quality, in particular can consist of ferritic steel. This can reduce the overall cost.
  • connection between the motor flange and the outlet flange is formed by a separate part, which is connected on the one hand to the motor flange and on the other hand to the outlet flange, in particular by welding.
  • This embodiment has the advantage that each part can be manufactured separately and that all three parts can be made of different materials. This can further reduce costs. Motor flange and outlet flange can also be connected directly to each other. This only requires two parts.
  • the motor flange can be designed as a collection flange for a plurality of cylinders. But it is also possible to form the motor flange of several single or double flanges. In this case, according to a further embodiment of the invention, only a part of the single or double flanges may be connected to the outlet flange. For example, the outlet flange may be connected to a double flange for two cylinders. A double flange is overall stable enough to take the load from the outlet flange.
  • the other motor flanges can be designed as a single flanges, resulting in a material saving and thus cost reduction.
  • the manifold pipes are preferably flexible designed to compensate for different thermal expansions can.
  • the flexible configuration can be effected in particular by selecting the material and / or the wall thickness and / or the shape of the cross section and / or the pipe curvature. The thinner the wall thickness, the larger the wall thickness Flexibility. On the other hand, an oval cross-section leads to increased flexibility about the longitudinal axis of the oval.
  • the motor flange and the outlet flange may be formed as stamped, stamped or forged parts.
  • the flanges are thus inexpensive to produce.
  • the illustrated in the figures, designed as Einwandkrümmer manifold comprises a motor flange 1, an outlet flange 2 and four manifolds 3, which are each connected at one end to the motor flange 1 and at its other end to the outlet flange 2.
  • the manifolds 3 are connected via a collector housing 4 with the outlet flange 2. That is, to the outlet flange 2, a collector housing 4 is connected, which has four inlet openings 5 for the manifolds 3 and an outlet opening 6, which opens into the outlet flange 2.
  • the motor flange 1 by two Einzelflansche 1 1 and a double flange 1 2 is formed. While the individual flanges 1 1 are connected only to the cylinder head, the double flange 1 2 , as can be seen in particular Fig. 3 detects, additionally connected to the outlet flange 2. For this purpose, the double flange 1 2 next to the straight flange portion 7 and an S-shaped curved connecting portion 8. With this connecting portion 8 of the double flange 1 1 is welded to the outlet flange 2. In principle, it would also be possible to manufacture the outlet flange 2 and the double flange 1 2 in one piece. However, the two-piece design has the advantage that both parts can be made of different materials.
  • the double flange 1 2 made of austenitic steel and the outlet flange 2 of ferritic, ie normal steel.
  • the connecting portion 8 it would also be possible to manufacture the connecting portion 8 as a further separate part and to connect to the double flange 1 2 , in particular to be welded. Then this could also be a separate material used.
  • connection 8 between double flange 1 2 and outlet flange 2 is a load-transmitting connection between the two components.
  • load acting on the outlet flange 2 can be transmitted to the double flange 1 2 and thus to the engine block.
  • Components attached to the outlet flange 2, such as turbochargers or close-coupled catalytic converters, can thereby be fastened to the engine block without the manifold pipes 3 having to transfer the load.
  • the manifold pipes 3 can be optimized in terms of their flexibility, in particular more flexible to compensate for different thermal expansions. Eventually, the material thickness of the manifold pipes can be reduced, whereby weight can be saved. In addition, flexibility can be achieved by choosing the material of the manifold pipes 3, are influenced by choice of the shape of the cross section and by the curvature of the tubes 3.
  • the individual flanges 1 1 and the outlet flange 2 can be produced as stamped parts, the double flange 1 2 as a stamped and bent part. Another possibility is in the production as a forged part.
