    Description
    [001] The present invention relates to a process for assembling a motor module for a motor vehicle that includes a cylinder head cover and a camshaft rotatable on the cylinder head cover.
    [002] To reduce the effort of assembling a motor vehicle motor and to reduce maintenance costs in stock and logistics in assembling engines, already assembled engine modules are supplied to car manufacturers, by suppliers and ready, being delivered directly to the assembly line. These engine modules consist, for example, of a cylinder head cover and a camshaft mounted there. In the process of assembling the engine, it will only be necessary to attach this module to the cylinder head of the engine.
    [003] European patent EP 1 115 770 B1 describes an assembly process for an engine module that consists of a cylinder head cover and a camshaft mounted there. In this known assembly process, a cylinder head cover is provided with passages through which the cylindrical support shaft of the subsequent camshaft is fitted. The components to be fastened to the camshaft, such as the cams themselves, need to be integrated in such a way in special fittings that are positioned precisely in the required angular alignment and in the required axial position. If the cylinder head cover and the components to be mounted on the support axis are aligned with their passages to receive the support axis in a reciprocal direction at the right position and angles, then the support axis will be crossed by the passages. According to an embodiment of the process described in European patent EP 1 115 770 B1, the components to be attached to the support shaft will be heated before the transfixation of the support shaft and this support shaft will be cooled to guarantee an introduction to be force of the support shaft. The cams will be fixed by a pressing joint on the support shaft. To produce this press connection, in the European patent EP 1 115 770 B1 different possibilities are indicated. On the one hand, the pressed connection can be produced by the fact that the support shaft is introduced through a press using force. Another possibility of producing the pressed connection is that the inserted support shaft is subjected to a high pressure internal deformation so that subsequently or simultaneously the outer diameter of the shaft will be enlarged at least in the area of the components.
    [004] The known process of the patent EP 1 115 770 B1 is complex and linked with high costs because the components to be attached to the support shaft even before the introduction of the support shaft need to be positioned and aligned with such precision as afterwards they should be arranged on the posterior camshaft. To achieve this goal, retaining elements of conformation and special modeling are required, within which the components can be placed in the correct position and angle. For all components, the retaining element must have a specially shaped retaining fitting. The production of these re-tempting elements is complex and expensive. In addition, for different camshafts, different retaining elements are different. Why it happens that the angular alignment of the cams with respect to the camshaft support tube depends, for example, in fact whether in the case of a cam shaft for a four-cylinder engine or a six-cylinder engine.
    [005] The objective of the invention lies in proposing a process for assembling an engine module that consists of a cylinder head cover and a camshaft, in which special conformation devices are not required to retain and dispose of components to be attached to the support shaft within the respective correct angular position and which can be used flexibly for different cam axes that have cams with varying angular positions.
    [006] A wide advantage of the process according to the invention is that the components to be attached to the support axis, such as, for example, cams, sensor wheels, etc. prior to the introduction of the support shaft, they are only fixed in such axial positions that do not correspond to the axial positions that these components occupy on the final mounted cam shaft. Therefore, the components - in relation to their angular position in relation to the support axis - do not yet need to be precisely aligned. In the process according to the invention, precise alignment of the components can be dispensed with completely before the introduction of the support shaft. Therefore, no special retaining devices are required, by which prior to the introduction of the support axis, the precise angular positions of the different components to be attached to the support axis are determined, this determination being made in relation to the support axis.
    [007] In the process recommended by the present invention, components, after insertion of the support axis, will be attached to this axis due to the fact that either the components have been pressed over the diameter enlargements allocated to them by the support axis or that they are pressed in the enlargements of diameter allocated to the components in the passage openings of the said components. In this case, the respective angle position of all individual components relative to the support axis, can be determined in a simple way by the fact that the support axis will be rotated - relative to the respective component - at a certain angle so that the position Relative angular required of the component in relation to the support axis will be achieved. Therefore, with the process according to the invention, it is possible to assemble different modules with well-differentiated cam shafts, without requiring a special retaining device for each separate cam axis in order to ensure the correct positioning and alignment of the cams. on the support shaft. In this way, with the process according to the invention, it can be achieved in a cost-effective and simple way for differentiated engines or engine variants, to produce modules with differentiated camshafts, in which the components to be fixed on the camshaft are arranged in different angular positions in relation to the support axis.
    [008] According to an embodiment of the invention, the widening in diameter will be applied by a mechanical deformation process, such as, for example, roller polishing.
    [009] The fittings for mounting the cylinder head cover and the bearing segments of the support shaft, according to the invention will be so dimensioned that the bearing fittings, in final state assembled from the cylinder head cover together with the bearing segments form sliding bearings. The mounting segments of the support shaft can therefore be ground in such a way that the support shaft, in a cooled state, has the slightly smaller diameter required for forming a sliding bearing than the bearing housing. cylinder head cover.
    [0010] In the following the invention will be explained in more detail on the basis of schematic drawings presented the principle of the invention. The figures show:

    [0019] Figure 9 - schematic presentation of a hollow support shaft for an adjustable camshaft, with two different components 5 and 5 ', of which only component 5 will be joined approving the rotation with the support shaft.
    [0020] Figure 10a - 10d - the sequence of the process steps in the production of an adjustable kennel axis with two different components 5 and 5 'according to figure 9.
    [0021] Figure 11 - a cam shaft mounted and adjustable with a hollow support axis and an internal axis there concentrically arranged and rotatable relative to the support axis.
    [0022] In figure 1, a support axis 4 prepared for use in the process according to the invention is shown. The support axis 4 has several segments with different diameters. The dimeters designated with D1 form the bearing segments 8 of the support shaft 4 which in the final assembled state of the module form with the bearing housings 2 of the cylinder head cover 1 bearing supports for the cam shaft 3. D2 designates the diameter with which the components 5, to be fastened to the support axis, will be previously positioned before producing a firm connection with the support axis 4. D3 designates the outside diameter of the enlargements of diameter 7. In the execution example presented, two different possibilities are indicated for conformation of the widening of diameter 7. The widening of diameter 7 on the left, shown in figure 1 on the left side, was produced by roller polishing. Its width B is adjusted to the component stuck in the widening of diameter 7.
    [0023] The diameter widening shown on the right side of figure 1, in turn, was produced by a grinding process, that is, the support axis 4 was ground from a larger diameter to a D3 diameter. In the execution examples shown below of the invention, only the enlargements of diameter produced in a roller polishing process will still be presented.
    [0024] Figure 2 shows a component 5 at room temperature and must be attached to the support axis 4 during the module assembly. The component shown in figure 2 as an example is a cam that has a through opening 6 with a diameter DBT and a width A. With the process according to the invention, not only cams can be attached, but also other components as for example, sensor wheels and similar units, in the right position, being attached to the support shaft 4. In the context of the present description of an example of concrete implementation of the invention, for the sake of simplicity only the example of cams as components will be considered to be attached to the support shaft.
    [0025] Figure 3 shows the step of the process of transfixing the cooled support shaft 4 through the bearing housings 2 of the cylinder head cover 1 and the passage openings 6 of the heated components 5. The presentation is merely schematic and to facilitate understanding, the cylinder head cover 1 is not showing any other components or details. The outside diameter of the bearing segments 8, which has been reduced due to cooling of the support shaft 4, is designated with D1 'and the reduced diameter of the enlargements of diameter 7 is designated with D3'. The enlarged diameter of the transfixation passages of the components 6, enlarged as a result of the components 5, is designated with DBT '. In addition, DL designates the diameter of the bearing housings 2 cylinder head cover 1.
    [0026] The diameter D1 of the bearing segments 8 and D3 of the flares of diameter 7, as well as the diameter DBT of the passage openings 6 of the components, in the context of the production of the respective components were dimensioned in such a way that the diameters D1 ' and D3 'of the cooled support shaft 4 are slightly smaller than the diameter DL of the bearing housings 2 and the diameters DBT' of the heated components 5. In this way, the support shaft 4 can be easily transfixed by the bearing housings 2 and the passage openings 6.
    [0027] The components 5 will be positioned in relation to the cylinder head cover 1 without having to look at the angled alignment of the components in relation to the support axis 4. In this case, the passage openings 6 will be so aligned that are aligned with the bearing housings 2 of the cylinder head cover 1. The heating of the components 5 can take place before or after positioning. A suitable heating process is heating by means of induction. The support shaft 4 can, for example, be cooled with liquid nitrogen or another refrigerant.
    [0028] Figure 4 shows the final and introduced state of the support axis 4 with the support axis 4 still cooled and with the components 5 still heated. Starting from this state, the support axis 4 will now be heated and the components 5 will be cooled until the two components have acquired room temperature. This state after the temperature compensation is performed is shown in figure 5. In this state, components 5 are pre-positioned in a segment with diameter D2. The DBT diameter of the passage openings 6 is slightly larger than the diameter D2, so that the relative angle position of the components 6 with respect to the support axis 4 can be freely varied by simply rotating the support axis 4, which can be regulated in any desired way.
    [0029] Figure 6 shows schematically how a first component 5 will be pressed on the widening of diameter 7 by pressing, being fixed on the support shaft 4. Before component 5 is pressed on the widening of diameter 7, by turning of the support axis4, the desired angle position of the component 5 with respect to the support axis 4 will be adjusted. This is indicated in figure 6 by the arrow 10. Arrow 11 indicates the direction of the pressing for the component 5. In an analogous way, the fastening process for the second component 5, in figure 7. Here too, in a very simple way, the desired angle position of component 5 in relation to the support axis 4, will be regulated by a simple rotation of the support axis 4.
    [0030] It is understood that in this same way other components can be attached to the support axis 4. Therefore, as the process according to the invention becomes possible in a simple and cost-effective way with the same device and with the same procedure to produce differentiated modules to the cylinder head and camshaft cover, that is, for example, a module with a camshaft for a 6 or 8 cylinder engine. The process according to the invention therefore increases the flexibility of production because different modules can then be assembled without complex modifications of the assembly device.
    [0031] Figure 8 finally shows, schematically, the module already assembled and finished of component 5 is joined with an adherent union and with a positive union with the support shaft 4. The bearing segments 8 form with the bearing inserts 2 cylinder head cover 1 slide bearings.
    [0032] According to a process modality according to the invention, the components 5 to be joined with the support axis 4, in the realization of the process step in which these units, in a predetermined sequence relative to the support axis 4, will be so positioned that their through-openings 6 are arranged in line with the bearing housings 2 of the cylinder head cover 1, being applied in axial positions that do not correspond to the axial positions that will be occupied by these components 5 on the camshaft 3 final assembled, and in an additional character being still in such a way that after the temperature compensation achieved by heating the support axis and / or cooling the components 5, between the support axis 4 and the components 5, are kept fixed, separably in a partial segment of the diameter 7 flares allocated to them respectively. In this way it becomes possible to fix the components 5 in a desired and determined relative position with respect to the support axis 4, with the fixation being made to this axis separately. When, for example, the components 5 are formed by cams, then all the cams 5 can be fixed so separately on the support axis 4 that their cam projections point in the same direction. The advantage of this procedure is that the pressed connection to be made after positioning the cams, between the cams 5 and the support shaft 4, can be made in a simple way in an automated procedural step. In the context of an automated production of the pressed joint between the components / cam 5 and the support shaft 4 with the aid of an applied or introducing pressing device, it will be advantageous when the relative position of the components / cam 5 is fixed predetermined. The device therefore does not require any means to determine for each component / cam 5 its effective relative position existing in the circumferential direction before the necessary angular position is adjusted by turning the relatively component support cam / cam 5. component / cam 5 on the support shaft 4.
    [0033] Expressed in another way: when the relative angular position of the component / cam 5 in relation to the support tree 4 after its positioning and before the production of the pressed connection, this relative angle position is not known for a temporary fixation of the components / cam 5 on the support axis 4, so before the initially pressed connection is formed, the relative angle position of the components / cam 5 must be determined before it can be determined at which angle the support axis 4 will have to be rotated to ensure the desired angle position of the component / cam 5 on the support shaft 4. This makes it difficult to automate the pressing applied to the components / cam 5 on the support shaft 4, that is, the pressed introduction of the support shaft 4 into the components / cam 5. When, in turn, the components / cam 5 after positioning always in the same angular position are securely attached to the support axis 4, then the dete's working step can be dispensed with rmination of the relative angle position of the components / cam 5 in relation to the support axis 4 because the relative angular position will already be known in advance. The device for producing the pressed connection between the components / cam 5 and the support shaft 4 can therefore be shaped in an essentially simpler way and the process according to the invention for assembling the cam shaft can have a faster sequencing . The cadence time will be markedly increased, and a more economical operation of the production line will be achieved.
    [0034] Figures 9 to 11 show a modality in which the process according to the invention is used in the context of the assembly of an adjustable camshaft. In this embodiment, the support axis 4 is formed as a double axis. Inside the support axis 4, an internal tree 20 will be arranged concentrically towards the support axis 4, the internal tree 20 being rotatable with respect to the support tree 4. Components 5 are provided that in the above described way are joined by a pressed connection with support shaft 4. In addition to components 5, at least one other component 5 'is provided, which will not be joined with support shaft 4, but it will be connected to the swing test with the inner shaft 20. The connection approves the swing of the component 5 'with the internal tree 20 it is verified, for example, through a pin connection, as will be explained later on. In this way, the components 5 'together with the internal shaft 20 are rotatable with respect to the support axis 4 and the components 5 fixedly joined with the support axis 4.
    [0035] The components 5 and 5 'will preferably be formed by cams through which the gas exchange valves of a combustion engine are activated. By a relative rotation of the internal axis 20 in relation to the support axis 4, it is possible to change the opening and closing moments of the valves activated by the cams 5 '. In this way, an adjustable camshaft is available, which was produced by using the process according to the invention. The support axis 4 shown in figure 9 is shaped like a hollow tree. Inside the support tree 4, an internal axis 20 is arranged concentrically in relation to the previous unit (compare figure 11). The internal axis 20 is rotatable with respect to the support axis 4. The support axis 4 shown in figure 9 has two different enlargements of diameter 7, 7 '. The first widening of diameter 7 serves to form a pressed connection with component 5 in the manner described above. The second widening of diameter 7 'serves for separable fixing of the component 5' on the support axis 4 as will be described in more detail below. In addition, the support shaft 4 has an opening 21. The component 5 'which in the example shown is shaped like cams, has a perforation 23. The internal shaft 20 to be arranged on the support shaft 4 is hollow (see figure 11 ) is not shown in figure 9. The opening 21 and the hole 23 are used to fix the rotation of the component 5 'with the internal shaft 20. This will be explained later on based on figure 11.
    [0036] In figure 10a - 10d, the production process according to the invention is shown in the example of the assembly of an adjustable camshaft. Figure 1a shows the insertion on the support shaft 4 in the recessed housings of the bearing 2 and in the passage openings 6. The support tree 4 has been cooled so that its diameter is reduced and the support shaft together with the flares of diameter 7, 7 'can be traversed by the passage openings 6. The pan 24 shows the insertion direction.
    [0037] Figure 10b shows the state after carrying out the temperature adjustment between the support shaft 4 and the components 5, 5 'and the bearing fittings 2. The support tree 4 has reached its axial theoretical position. It was heated in such a way that its diameter increased again. The component 5 is so positioned in the axial direction that it has been contracted over a reduced partial segment of the widening of diameter 7. In this way, a separable fixation of the component 5 has been produced in the support tree 4. The component 5 can without any problem be moved again and removed from the partial segment of the widening of diameter 7 so that before the final pressing of the component 5 on the support tree 4, the desired angular position between the component 5 and the support axis 4 is regulated in a comparable way the component 5 ' in the axial direction it is so positioned that it has been contracted hot on the widening of the diameter 7 '. In this way, the component 5 'is kept separably fixed on the support axis 4. The component 5' can easily be moved and removed from the diameter widening in order to adjust the desired relative angle position between the support axis. 4, the inner axis 20 not shown and the component 5 '. In this way, the components 5 'can be kept fixed and separable in a desired angular position desired and previously known, on the support axis 4. In this way the automation of the subsequent pressing of the components 5 on the support tree 4 will be facilitated, or that is, the subsequent pin connection between the component 5 'and the internal axis 20 not shown (compare figure 11) and the lead time in the assembly of the camshafts will be increased.
    [0038] Figure 10c shows how the component 5, by loosening the temporary fixation, was moved and removed from the widening of the diameter 7 in the direction of the arrow (arrow 25) in the same way the component 5 'of the component can also be removed and moved. 7 'diameter widening.
    [0039] After the component 5 has been removed from the widening of diameter 7, the desired relative angle position between the component 5 and the support axis 4 will be adjusted by means of the rotation of the support axis 4. This is indicated in figure 10d by the arrow 26 bent on the right side. Then, component 5 will be pressed in the direction of arrow 27 axially over the widening of diameter 7, with which a permanent pressed connection is formed in the form of a longitudinally pressed joint between component 5 and the support shaft 4. In addition , the pressed joint can also be formed with a positive union.
    [0040] Similarly, component 5 'can now also be moved to its terminal position for a slew-proof connection with the internal axis 20, not shown in figures 10a - 10d. For this purpose, initially component 5’s will be removed from the widening of diameter 7 ’, so that the support axis 4 is freely rotatable in relation to component 5’. Then, the support axis 4 and the inner axis 20 not shown will be rotated in such a way that the opening 21, the first hole 22 in the inner axis 20 (not shown) and the second hole 23 in the component 5 'are reciprocally aligned. After that, a connecting pin 24 will be pressed through the opening 21 inside the first hole 22 and in the second hole 23, with which the component 5 'will be connected to the swing proof with the internal axis 20. Then, the component 5' through of rotation of the internal axis 20, it can be rotated in relation to the support axis 4.
    [0041] The assembled state of the adjustable camshaft is shown in figure 11. Bearing housings 2 form sliding bearings for the support shaft 4. At the ends of the support shaft 4, the inner shaft 20 protrudes from the support shaft 4. Component 5 is joined by means of a pressed joint with adherent union, or positive union, or adherent union with the support shaft 4. In the area of component 5 ', the arrangement of the axes in axial semi-cut is shown. The hollow support shaft 4 surrounds the inner shaft 20. A coupling pin 24 is pressed through the opening 21 (in figure 11 not shown) on the support shaft 4 inside the hole 22 of the inner shaft 20 and in the hole 23 of the component 5 '. An annular slot is provided between the support axis 4 and the inner axis 20. Through the connecting pin 24, the component 5 'is connected to the swing proof with the internal shaft 20. The component 5' can be rotated in relation to the support shaft 4, the internal axis 20 being rotated in relation to the support axis 4. In figure 11, on the right side of component 5 ', an enlargement of diameter 7' can be recognized on which component 5 'was previously separable.
