    Device for determining position and / or adjusting at least one
    Shaft of an internal combustion engine
    The invention relates to a device for determining the position and / or adjusting at least one shaft of an internal combustion engine. The invention also relates to a method for determining the position and / or adjusting at least one shaft of an internal combustion engine.
    The monitoring and in-phase adjustment of the shafts of internal combustion engines, in particular the crankshaft and the camshafts, is of the utmost importance for the correct operation of an internal combustion engine. The coordination of the phase position of the crankshaft and camshaft as well as several camshafts with each other has a major impact on the timing, opening and closing times of the gas exchange valves and thus on smooth running, emission behavior and consumption of the internal combustion engine. Especially with new engine generations with cylinder deactivation, Miller and other cycles, the timing of the shafts themselves and among themselves is of great importance.
    DE 10 2004 041 526 A1 describes a method for this where deviations from angular positions are monitored or, if necessary, indicated by means of an error signal. With the help of an absolute angle encoder, an attempt is made to record the current camshaft position with an accuracy of 1 ° -2 ° so that the control unit functions based on it can be performed reliably.
    Furthermore, it is common nowadays to use camshaft adjusters for adapting the relative angular position of camshafts to crankshafts during the operation of the internal combustion engine, such as, for example, the
    DE 10 2009 055 272 A1 describes. DE 10 2008 010 835 A1 describes one
    Arrangement known, which sets a predeterminable angular position of a crankshaft when the internal combustion engine of a motor vehicle is switched off via measuring and braking devices. This makes it easier to start the internal combustion engine even without a starter or start generator.
    In particular during installation and also during service work on the internal combustion engine, it is of the utmost importance to maintain or optimally adjust the angular positions in this regard. For example, the camshaft and crankshaft with 1/25
    PW31409AT
    AVL DiTEST GmbH mechanical tools fixed to their zero point. The camshaft drive wheels are tightened at this position - the zero point is determined by reference surfaces on the camshaft or engine housing and usually corresponds to the top dead center of a cylinder. DE 39 26 430 A1 and DE 101 49 109 C1 describe methods and devices for the in-phase adjustment and mounting of at least two camshafts. A disadvantage of these solutions is, in particular, that although they can be installed in the correct phase, subsequent adjustments cannot be addressed: For example, when installing or replacing the toothed belt, it can occur due to mechanical forces (e.g. valve spring pressure, belt tension) or tolerances The shaft positions are adjusted as soon as the change has been made and the motor is started up again. The exact position or phase of the waves cannot be determined and cannot be adjusted.
    It is therefore an object of the invention to remedy the disadvantages of the prior art and to provide a solution which enables the position and angular position of a motor shaft, in particular of camshafts and crankshafts, to be checked and adjusted in a simple and reproducible manner.
    This object is achieved according to the invention with a device mentioned at the outset in that the device has at least one bracket element that can be detachably attached to the internal combustion engine, at least one position sensor element that can be releasably attached to the shaft, and at least one sensor element that can be detachably attached to the bracket element for determining the shaft position using the position sensor element.
    The shaft position is understood here to mean in particular the phase position of the shaft or its angular position.
    Thanks to the invention, it is possible to determine the shaft position of at least one shaft, possibly also several shafts, and to take countermeasures if the angle values do not correspond. Thanks to the use of a console element and sensor element that can be attached to it, the position and thus the control times can be adjusted with minimal disassembly. At the same time, the adjustment work takes up little time / 25
    PW31409AT
    AVL DiTEST GmbH feasible and the device according to the invention can be quickly adapted to other internal combustion engines.
    In a particularly easy-to-use variant of the invention, the position transmitter element and the sensor element are combined in a common sensor component.
    The console element advantageously has internal combustion engine positioning elements, which are preferably arranged on the internal combustion engine side, i.e. on the side of the console element facing the internal combustion engine, and / or sensor positioning elements, which are preferably arranged on a side of the console element facing away from the internal combustion engine. This makes it possible to position the device according to the invention reproducibly on the internal combustion engine without great effort and also to correctly attach the sensor elements.
    In a variant of the invention, the console element on the internal combustion engine side, that is to say on the side facing the internal combustion engine in the assembled state, has at least one interchangeable console adapter element on which internal combustion engine positioning elements are arranged. This makes it easy to adapt to different types of engines or internal combustion engines. The console adapter element can be releasably connectable to the console element, for example by snap or screw connections.
    In a further variant of the invention, the position transmitter element is arranged on an adapter element that can be releasably and non-positively and / or positively connected to the shaft on a connection side and that the position transmitter element can be arranged or releasably arranged on a sensor side opposite the connection side. The adapter element can be used to adjust the shaft by attaching a tool that is operated by a user or automatically. No tools have to be attached to the shaft itself, so that it is protected and wear is reduced.

    For this purpose, it is furthermore advantageous if the console element has at least one adjustment recess, which in the assembled state radially extends from an axis that is aligned with the shaft axis. In this case, the adjustment recess can run completely in the console element, can each run partially in the console element and an adapter element or as a recess on the internal combustion engine or sensor side. Through this adjustment recess, the tool can be inserted and the shaft can be adjusted without the device or the positioning element having to be removed. The position can be measured simultaneously with the adjustment, which saves a lot of time and increases accuracy.
    The sensor element is advantageously a magnetic sensor or an optical sensor. Accordingly, that is also
    Position sensor element designed accordingly, e.g. as a magnetic element for the magnetic sensor or as an optical disk for the optical sensor. Potentiometers and other known technologies can also be used here.
    In a variant of the invention, an evaluation unit connected to the sensor element is provided and / or an interface for connection to at least one of the following elements: computer, computer network, data acquisition device, data storage device. This simplifies operation of the device and processing of the data obtained thereby.
    The object of the invention is also achieved according to the invention by a method mentioned at the outset by the following steps:
    a) attaching a console element to an internal combustion engine;
    b) attaching at least one position transmitter element to the end face of at least one shaft of the internal combustion engine;
    c) attaching at least one sensor element to the side of the console element facing away from the internal combustion engine;
    d) determining the angular position of the at least one shaft with the sensor element.

    AVL DiTEST GmbH
    In a variant of the invention, steps b) and c) are combined into a common step by attaching a sensor component which has the position transmitter element and the sensor element.
    The invention thus allows simple and rapid position determination and adjustment of shafts of an internal combustion engine and can be quickly adapted to different engine types.
    In a variant of the invention, step b) has the following sub-step:
    b1) fastening an adapter element with a connection side and a sensor side on the shaft, the connection side being arranged on the shaft and the sensor side having a position transmitter element;
    or b1) fastening an adapter element with a connection side and a sensor side on the shaft, the connection side being arranged on the shaft;
    b2) connecting the sensor side with a position sensor element.
    A tool for adjusting the motor shaft can be attached to the adapter element so that the force does not act directly on the motor shaft, which can prevent damage.
    In a further variant, the following steps are also provided:
    e) rotating the at least one shaft through a certain angular range, preferably greater than 360 °;
    f) determining the angular position of the at least one shaft with the sensor element and comparing it with the angular position from step d).
    This allows malpositions or functions of the shaft to be determined quickly and easily.
    As a last step, the shaft is advantageously readjusted by rotating the adapter element about a predefinable one or in the course of / 25

    Procedure determined the misalignment range. This can correct malpositions and
    Tax times are corrected.
    The invention is explained in more detail below in a non-restrictive exemplary embodiment, which is shown in the figures. In it shows
    Figure 1 is a schematic plan view of the end face of an internal combustion engine.
    2 shows a perspective view of a console element of a device according to the invention;
    3 shows a perspective view of an adapter element;
    4 shows a sectional view of a sensor element of the device according to the invention; and
    Fig. 5 is an exploded perspective view of a device according to the invention in use.
    For reasons of clarity, similar elements are identified in the following figures with the same reference symbols.
    The exemplary internal combustion engine 100 shown schematically in FIG. 1 with a plurality of cylinders lying in a row (not shown) has a crankcase 101 and a cylinder head 102 in which two camshafts 1, 2 are mounted. A crankshaft 3 is mounted in the crankcase 101, the crankshaft gear 30 driving the camshaft gears 10, 20 or the camshafts 1, 2 mounted in the cylinder head 102 via a drive element 4, for example a toothed belt or a chain. A water pump is also driven by the drive element 4 via an associated water pump wheel 50, and a tensioning wheel 60 is additionally provided.
    During assembly and service work of the internal combustion engine 100, the two camshafts 1, 2 must be assigned in phase with one another or with the crankshaft 3; this assignment must be present during the entire operation so that the timing and actuation times of the intake and / or exhaust valves are correct. Otherwise, it may lead to increased fuel consumption or higher / 25

    Emissions come, with large deviations at worst at one
    Placing the valves on the piston and thus can lead to engine damage.
    According to the invention, the device shown in FIGS. 2-5 is therefore proposed. This device 6 has a console element 7, at least one position transmitter element 8 ', 8' 'which can be releasably attached to a shaft 1, 2 of the internal combustion engine 100 and at least one sensor element 9', 9 '' which can be releasably attached to the console element 7 for determining the shaft position using the Position sensor element 8 ', 8' '. The position transmitter element 8 ″, 8 ″ ’can either be mounted directly on the shaft ends of the shafts to be adjusted or via intermediate pieces, e.g. Adapter elements 18 ', 18' '(see FIGS. 3 and 5) or intermediate shaft pieces 11 (see e.g. FIG. 4) can be arranged.
    FIG. 2 shows the console element 7, which can be detachably fastened to an internal combustion engine 100, for example by means of screws or the like. The positions of the screw holes provided for this purpose in the console element 7 act as internal combustion engine positioning elements 70, 71, 72, which correspond to corresponding positioning elements 70 ″, 71 ″, 72 ″ on the internal combustion engine 100 and thus enable a reproducible arrangement of the console element 7 on the internal combustion engine 100. The positioning elements 70 ″, 71 ″, 72 ″ on the internal combustion engine 100 can, for example, be corresponding drill holes for receiving fastening screws, which are aligned with the screw holes in the console element 7. Reference surfaces (not shown in the figures) on the internal combustion engine side on the console element 7 and on the internal combustion engine 100 are also possible.
    The console element 7 is dimensioned such that in the assembled state its extension in a direction normal to the camshaft axes 1a, 2a is greater than in a direction parallel to the camshaft axes 1a, 2a. The shape can be chosen so that it can be used in confined spaces and minimal disassembly is required.
    In order to be able to use the device 6 according to the invention easily in various motors or internal combustion engines 100, a console adapter element 700 is provided in the exemplary embodiment of the console element 7 according to FIG. 2, which (additional) internal combustion engine positioning elements e.g. in the form of / 25
    PW31409AT
    AVL DiTEST GmbH
    Can have reference surfaces. If the device 6 is to be used with another motor, the adapter element 700 is simply exchanged and further use of the other components of the invention
    Device 6 is possible.
    The console element 7 has at least one shaft opening 71a, 72a in the form of a recess breaking through the console element. The shaft opening 71a, 72a is designed in such a way that, when the bracket element 7 is in the assembled state, it is flush with the shaft to be measured or adjusted, e.g. of the camshaft 1, 2 or crankshaft -, the diameter of the shaft opening 71a, 72a in the direction normal to the shaft axis 1a, 2a being larger than the diameter of the shaft 1, 2, 3 in order to process or adjust the shaft position or to allow easy attachment of the console element 7.
    In addition, the console element 7 has sensor positioning elements 90 ″, 91 92 ″, 93 ″, which in the exemplary embodiment shown are arranged on the side of the console element 7 facing away from the internal combustion engine 100 in the assembled state. With these sensor positioning elements 90 ', 91', 92 ', 93', which with corresponding positioning elements 90, 91, 93 (see, for example, FIG. 3 or FIG. 5, where further positioning elements are covered by the sensor elements 9 ', 9' ') interact on the sensor element 9 ', 9' ', the sensor element 9', 9 '', the console element 7 and the internal combustion engine 100 can be reproducibly connected to one another.
    The sensor positioning elements 90 ', 91', 92 ', 93' shown in FIG. 2 are each arranged in pairs on opposite sides of the shaft openings 71a, 72a and each have a teardrop shape, that is to say they have a circular area, a slot-shaped recess in the radial direction leads away. The respectively opposite sensor positioning elements 90 ″, 91 ″, 92 ″, 93 ″ are oriented in opposite directions, so the slot-shaped recesses run in opposite directions starting from the circular area. As a result, the positioning elements 90, 91, 93 of the sensor element 9 ', 9' 'can be brought into engagement with the circular regions - a rotation of the sensor element 9', 9 '' counterclockwise about an axis parallel to the camshaft axis 1a, 2a locks this Sensor element 9 ', 9' 'in one / 25
    PW31409AT
    AVL DiTEST GmbH reproducible position with the console element 7. Turning clockwise releases the lock.
    2 is intended for use with two camshafts 1, 2 and has two shaft openings 71a, 72a through which the camshaft ends are accessible when the console element 7 is mounted.
    In order to make it possible to adjust the shaft 1, 2, 3 and thus correct the angular position, an adapter element 18 'can be provided, as shown in FIG. 3. The adapter element 18 'has a connection side 18a and a sensor side 18b. The connection side 18a can be connected to a shaft, counter-surfaces corresponding to key surfaces of the shaft ends being provided which permit unambiguous mounting. A sensor element 8 ', 8' 'is assigned to the sensor side 18b, which is either arranged directly on the sensor side 18b or can be connected to it - depending on the embodiment of the sensor element 9', 9 '', a suitable variant can be selected. The shaft position can be adjusted with a tool via the adapter element 18 'without the shaft having to be machined directly. For this purpose, the adapter element 18 'can be designed, for example, with a hexagonal profile.
    In the exemplary embodiment described, a magnetic sensor or magnetic Hall sensor is used as sensor element 9 ″, 9 ″ ″, as is shown by way of example in FIG. 4. The positioning elements 90, 91 are shown on the shaft side, which interact with the sensor positioning elements 90 ″, 91 ″ on the console element 7. Furthermore, a flange 10 for connecting the shaft (here the first camshaft 1) is shown, to which a shaft piece 11 mounted in a ball bearing 12 connects, on which a magnetic position transmitter element 8 'is arranged on the sensor side. Sensor element 9 'and position transmitter element 8' are thus implemented as a common sensor component 99. The position transmitter element 8 ′ can be detachably fastened to the camshaft 1 via the flange 10. This variant has the advantage that such a sensor component 99 can be connected to different internal combustion engines or motors via different console elements 7 - the console elements 7 each have the same arrangement of sensor positioning elements 90 ″, 91 ″, / 25
    PW31409AT
    AVL DiTEST GmbH differ in shape and form or in the arrangement of their internal combustion engine positioning elements 70, 71, 72 depending on the internal combustion engine.
    The magnetic position transmitter element 8 'or its movement is picked up by a sensor element 13 and fed to an evaluation unit 14 (see FIG. 5), which is not shown here, which can be done wired but also wireless. FIG. 4 additionally shows a brake 15, with which the sensor element 13 is locked in a zero position and the sensor can be zeroed. In addition to the Hall sensor, other sensor elements can of course also be used, such as potentiometers or optical encoders.
    5 now shows in an exploded view the use of the device 6 according to the invention using the example of two camshafts 1, 2: after removal of the corresponding covers and housing, the console element 7 is mounted on the internal combustion engine 100 or the cylinder head 102 (the arrangement in FIG. 5 shows the console element 7 before assembly). The internal combustion engine positioning elements 70, 71, 72 allow a clear, reproducible positioning of the console element 7 on the cylinder head 102. In the present case, the internal combustion engine positioning elements 70, 71, 72 are designed as screw receptacles in the console element 7, which are aligned with corresponding threaded openings in the cylinder head 102.
    A locking tool 16 is put in place, which interacts with positionally and precisely fitting geometries, for example wrench flats 200 (flattening, as can be seen in FIG. 5 for the second camshaft 2) of the camshaft ends of the camshafts 1, 2 and locks them in one position. The necessary maintenance work, for example changing the toothed belt 4, can then be carried out. The locking tool 16 is then removed again.
    Now adapter elements 18 ', 18' 'are mounted on the shaft ends, which can be reproducibly and detachably connected to the camshafts 1, 2 - in the exemplary embodiment shown by screws 17. The sensor sides 18b of the adapter elements 18' facing away from the internal combustion engine in the assembled state. 18 '' the position transmitter elements 8 ', 8' 'are assigned. The assignment can take place in that the position transmitter elements 8 ', 8' 'directly on the sensor sides 10/25
    PW31409AT
    AVL DiTEST GmbH
    18b are arranged, which can be advantageous, for example, when using optical sensors. This variant is shown or drawn in FIG. 5. According to the sensor variant in FIG. 4, the adapter elements 18 ″, 18 ″ ″ are connected to the position transmitter elements 8 ″, 8 ″ ″ via the flange 10. The adapter elements 18 ″, 18 ″ ″ are designed with a hexagonal profile on their circumference along the longitudinal extent, on which a tool can be attached.
    The sensor elements 9 ', 9' 'are then attached to the console element 7 in a direction along the camshaft axes 1a, 2a. The angular position of the respective camshaft 1, 2 or its relative position can be determined, for example by moving the camshafts 1, 2 by rotating the crankshaft 3 by 360 ° or 720 °.
    The measured values can then be transmitted to an evaluation unit 14. An angle of rotation display can thus be implemented or the angle deviations can be recorded — this can be done in the evaluation unit 14 itself or can be outsourced via an interface 140 to a computer, a computer network, another data acquisition or data storage device. Evaluation unit 14 and interface 140 can also be in combination, as shown in FIG. 5.
    If the measurement shows that one or both camshafts 1, 2 have to be readjusted, a tool can be provided via adjustment recesses 19 ', 19' 'which are embodied in the console element 7 and run radially to an axis that is aligned with the camshaft axes 1a, 2a (Not shown) can be set, which either an operator or automatically adjusts the camshafts 1a, 2a. As a result, force can be applied to the shaft in order to correct the position of the shaft, in particular its angular position or phase position. However, the tool does not have to start directly on the shaft, which has advantages from a wear perspective.
    These steps can be used both to adjust the shafts and to check the camshaft position in the event of engine problems, or when setting a lead angle.

    In addition to the described embodiment with two camshafts 1, 2, other shafts, e.g. only one camshaft 1, 2 or crankshaft 3, adjustable in the same way.
    The method according to the invention for determining the position and / or adjusting at least one shaft 1, 2, 3 of an internal combustion engine 100 thus comprises the steps of attaching a console element 7 to an internal combustion engine 100; Attaching at least one position transmitter element 8 ″, 8 ″ ″ to the end face of at least one shaft 1, 2, 3 of the internal combustion engine; Attaching at least one sensor element 9 ″, 9 ″ ″ to the side of the console element 7 facing away from the internal combustion engine 100; and determining the angular position of the at least one shaft 1, 2, 3 with the sensor element 9 ', 9' '.
    As described above, steps can be combined with one another by providing a sensor component 99 that has position transmitter element 8 ″, 8 ″ ″ and sensor element 9 ″, 9 ″ ″. The positioning element and the sensor element are thus attached simultaneously.
    Otherwise, the step of attaching at least one position transmitter element 8 ', 8' 'to the end face of at least one shaft 1, 2, 3 may have the following substeps:
    - Attaching an adapter element 18 ', 18' 'with a connection side 18a and a sensor side 18b on the shaft 1, 2, 3, the connection side 18a being arranged on the shaft 1, 2, 3 and the sensor side 18b being a position transmitter element 8', 8 '';
    or
    - Attaching an adapter element 18 ″, 18 ″ ‘with a connection side 18a and a sensor side 18b on the shaft 1, 2, 3, the connection side 18a being arranged on the shaft 1, 2, 3; and
    - Connecting the sensor side 18b with a position transmitter element 8 ', 8' '.
    This is followed by a rotation of the at least one shaft 1, 2, 3 by a certain angular range, preferably greater than 360 °; and determining the angular position of the / 25
    PW31409AT
    AVL DiTEST GmbH at least one shaft 1, 2, 3 with the sensor element 9 ', 9' 'and comparison with the previously determined angular position.
    Depending on the result, the final step is to readjust the shaft 1, 2, 3 by rotating the adapter element 18 ″, 18 ″ ″ by a preselectable angular range or determined in the course of the method.
    Between the steps mentioned, a locking tool 16 can be mounted one or more times in order to carry out work on the shafts 1, 2, 3 or on the internal combustion engine 100. This assembly is not specifically described and has no direct influence on the method according to the invention.
    The device according to the invention and the associated method thus allow the simultaneous measurement and setting of shaft angles of different shafts of an internal combustion engine, such as a camshaft or crankshaft.
