Definitions
- the invention relates to a bearing device for rotatably accommodating a control element in media-carrying lines of an internal combustion engine with bearing receptacles which rotatably accommodate the control element and can be fixed in the lines.
- control elements are preferably designed as a swirl flap, length-connection flap or the like, and the media-carrying lines can be designed, for example, as an intake system for vehicles.
- the flaps have neck-like extensions which extend essentially in the longitudinal direction and are rotatably mounted in the bearing receptacles.
- the neck-like extensions, the flap and the bearing receptacles are also penetrated by a steel shaft, which is torsionally rigidly connected to the flap.
- the shaft is rotated via an actuating unit, which is preferably designed as a stepping motor, as a result of which the adjustment angle of the flaps connected to the shaft changes.
- the adjustment angle of the plates is adjusted as desired via the position of the stepper motor.
- a shaft can also be rotatably received in the bearing receptacles, on which the flaps are arranged in a torsionally rigid manner are.
- the advantage of a steel shaft is that it can be slidably mounted, which prevents the flaps from jamming when the steel shaft expands.
- bearing blocks For the assembly of each individual flap in the intake pipe, at least three components are required in the prior art, which must be assembled, namely the flap two bearing receptacles to be placed on the nozzle-like extensions, which are often referred to as "bearing blocks".
- These bearing mounts consist of essentially plate-like plastic elements with a through hole acting as a bearing.
- the bearing mounts in turn must be used in the mounting position in mounts of the intake pipe. This assembly can be problematic in confined engine rooms.
- the attachment according to the prior art requires a relatively large amount of space, since the bearing blocks must have a certain minimum width in order to prevent undesired tipping.
- the invention is therefore based on the technical problem of further developing a generic bearing in such a way that its installation is simplified.
- the bearing receptacles can be connected to a bearing unit via an at least partially elastic connecting element and can be inserted together with the connecting element and the flap used into a receptacle provided in the intake pipe.
- the bearing unit can be preassembled externally by this configuration, so that it only has to be inserted into a receptacle provided for this purpose on the intake pipe when the engine is being assembled. There is no need to insert and precisely adjust the bearings, since the bearings are held in the desired position by the connecting element.
- the elastic design of the connecting element enables the bearing unit to be deformed in order to insert the otherwise rigid flap into the bearing openings of the bearing.
- the main advantages of the invention lie in the fact that it can be preassembled and the fact that the storage unit can be designed in any way, as a result of which there is great freedom for the design in terms of plastics technology.
- the bearing receptacles and the connecting element are preferably formed in one piece in a bush-like manner.
- This bushing that is to say the connecting element and the two bearings with the receiving openings provided in them, are preferably injection molded as a one-piece plastic part.
- glass fiber reinforced polyamides has proven to be particularly expedient since they are both temperature-resistant and resistant to the media occurring in the engine.
- the bearing unit is bent open and the flap is inserted. After the flap has been placed in the storage fixtures, the storage unit contracts again in its original shape.
- the bush has essentially the shape of a C-profile, which can be bent open at the parting plane.
- the intake pipe In order to simplify assembly and to precisely fix the bearing unit in the intake pipe, it is also advantageous to provide the intake pipe with a guide bar which engages in the bearing unit in the installed position in order to adjust it.
- the bearing unit can be provided with an upper edge in the installed position, which serves as a sealing edge for further assemblies to be attached to the intake pipe. So z. B. on additional sealing elements between the intake pipe and the cylinder head.
- 1 is a perspective view of the bearing unit with the flap installed
- 2 is a perspective view of the bearing unit without a flap inserted
- Fig. 5 is a side view in section along the line V-V of FIG. 2 and
- Fig. 6 is a perspective view of several bearing units inserted into an intake pipe.
- the bearing unit consists of an essentially rectangular, bush-shaped plastic body.
- a swirl flap 2 is rotatably inserted, which is also made of plastic.
- the bearing unit 1 is shown rotated by 180 degrees to the position which it occupies in the intake pipe 3 in accordance with FIG. 6.
- the flap 2 can be made of metal in order to prevent the detachment of plastic particles from the flap in the event of misfires.
- the bearing pins or extensions 22, 23 of the swirl flap 2 are extrusion-coated with a suitable plastic.
- the manufacture of the steel flap has the advantages that it has better dimensional accuracy and greater stability in the event of misfires.
- the cross section of the flaps can be made thinner in relation to the plastic version, which is accompanied by a reduction in the interference cross section of the flap in the tube.
- the bearing unit 1 has two bearing receptacles 10 and 11 which run essentially parallel to one another and which form the side legs of the bearing unit.
- the camp recordings 10 and 11 are each provided with holes 12 and 13 which are collinearly aligned. In these holes, the neck-like extensions of the swirl flap 2 are rotatably received in the installed position.
- the bearing receptacles 10 and 11 are connected to one another via an integrally molded connecting element 14.
- the connecting element forms the longitudinal leg and the bearing receptacles 10 and 11 form the transverse legs of the bearing unit 1.
- the connecting element 14 can be partially rotated in order to be able to insert the swirl flap into the bearing unit 1. After deformation, the bearing unit 1 returns to the original rest position. To insert a flap 2, the bearing seats 10 and 11 can be bent from their rest position into an angled position.
- the bearing receptacles 10 and 11 are again connected by legs extending at right angles to the bearing receptacles 10 and 11
- the legs 15 and 16 thus run essentially parallel to the connecting element 14 and are integrally molded onto the bearing receptacles 10 and 11.
- fixation legs 15a and 16a are formed in one piece at right angles to this.
- guide grooves 15b and 16b are formed on the inner sides of the fixing legs 15a and 16a which are to be jutted towards one another and into which a fixing web engages, which is provided, for example, on the suction pipe.
- FIG. 3 shows a perspective view of the swirl flap 2.
- the swirl flap 2 exists accordingly from an essentially flat flap 20, on which a bushing 21 for a shaft running in the longitudinal direction of the flap 2 is provided approximately in its center.
- the bushing 21 is formed on the inside as a square, in which the shaft, which is also designed as a square, engages and thus produces a torsionally rigid connection to the swirl flap 2.
- bushing-like extensions 22 and 23 are provided on the swirling flap 2, the outside of which have the contour of a cylinder and protrude beyond the front ends of the flap 20. With these extensions 22 and 23, the swirl flap 2 can be fixed in the bearing receptacles 10 and 11 of the bearing unit; in the recorded state, the extensions 22 and 23 are rotatably and free of play in the receptacles.
- FIG. 4 The assembly of the swirl flap 2 in the bearing unit 1 is shown in FIG. 4.
- the fixing legs 15a and 16a are slightly bent apart for assembly, the connecting element 14 being slightly bent at an approximately central bending point 14a until the extensions 22 and 23 can be inserted into the bearing receptacles 10 and 11 of the bearing unit 1 , When the fixing legs 15a and 16a are released, the bearing unit contracts again into its original shape.
- FIG. 5 shows that the inside of the legs 15 and 16 facing the swirl flap 2 is designed as a flow wall 15c and 16c which runs obliquely in relation to the flow direction of the air 4 and which directs the air flowing towards the air Swirl flap 2 brings up.
- the bearing unit 1 completely surrounds the swirl flap 2 in the closed position of the flap 2.
- the required flow properties can be achieved by using different bearing units 1 with differently inclined flow walls 15c and 16c realize without having to replace the entire intake pipe 3. Instead, only the bearing unit 1 is replaced by a correspondingly different one; the flow properties can be modified modularly by the bearing unit 1.
- the bearing unit itself represents the inner geometry of the intake pipe 3.
- the flow wall 15c is provided with a longitudinal groove-shaped recess 15d, with which a predetermined gap tolerance between the edge of the flap 2 and the bearing unit 1 can be maintained in the closed position.
- FIG. 6 shows a perspective view of an intake pipe 3 designed for a four-cylinder engine, into which four of the bearing units 1 provided with swirl flaps 2 are inserted.
- the bearing units 1 are rotated through 180 degrees to the orientations shown in FIGS. 1, 2, 4 and 5 in corresponding recesses provided on the intake pipe 3.
- the upper edges of the bearing units 1 in the installed position serve as sealing edges 17 for assemblies that are connected to the intake pipe, e.g. a main flange of a cylinder head. Due to the design of the bearing unit with a one-piece, bead-shaped sealing edge 17, which protrudes outwards, additional sealants between the intake pipe and the cylinder head can be dispensed with, which considerably simplifies the assembly of the assemblies.
- control element need not be designed as a flap.
- control element can also be designed as a roller, for example.
