    15 20 25 30 2 This leads to large variations in the tension of the drive belt and sometimes different directions of the pivot axes of the pulleys.
    The belt will, for example, flutter and slide as a result of the movements of the pulleys in relation to each other, which leads to wear of the drive belt with a shortened operating time as a result. Figure 1 shows a schematic figure of a motor 4 with a pulley 8 which is adapted via a drive belt 16 to drive an auxiliary system 10, e.g. a compressor. The drive belt transmits the rotation of the pulley 8 to a pulley 14 on the auxiliary system. The auxiliary system 10 is mounted on a platform 5 supported by a number of insulators 7.
    To improve the stability, a rod 3 can be provided with an alignment parallel to a line connecting the centers of rotation of the two pulleys to transmit some of the movement from the motor to the platform and thereby reduce the relative movement between these two fixed bodies (the motor and the compressor / platform ).
    The rod is shown in the schematic illustration in Figure 2. It reduces the variation of the belt tension but does not solve the problem that the orientation of the axes of rotation of the pulleys varies in relation to each other.
    The rod is also used as a tensioning device to give the belt a correct "preload".
    Since the bar is at a distance in the X-direction from the belt, a moment is created.
    This in combination with the free movement in all directions that the platform itself shows (the free movement depends on the design of the suspension, ie the insulators) means that the A / C compressor will swing and rock.
    Movements of the compressor in the Y-direction (see figure 2), which is in the direction of the rod, will be prevented by arranging the rod. Movements in the X and Z directions will not be prevented with the bar. The Z direction is perpendicular to both the X and Y directions.
    Rotations around the axes X, Y and Z axes will also not be prevented by the rod. 10 15 20 25 30 3 Rotation in X-direction can cause variation of the belt tension but does not cause a change in the direction of the pulley shafts. However, this makes rotations around both the Y and Z axes, which drastically reduces the life of the belt.
    The following are a number of patent documents showing various constructions in which a compressor is driven by a drive belt coupled to the crankshaft of an internal combustion engine.
    US-4540387 relates to a device for tensioning drive belts and comprises support arms for the pulleys and rods for adjusting the distance between the arms.
    Special soft guide rods ensure that the support arms are always parallel.
    US-6360712 relates to an arrangement for aligning and fixing a compressor to an engine. Furthermore, two upper arms are also described which are also used to fix the compressor to the engine.
    JP2009209998 shows a system in which a compressor is mounted in connection with a driving machine using a frame.
    JP2007051666 relates to a system comprising means for aligning pulleys relative to each other.
    US-2007/259745 relates to a system for a belt drive mechanism intended to tension the drive belt.
    To increase the life of the drive belt, it is necessary to prevent harmful movements between the two bodies, ie. the engine and the auxiliary system, so that they appear as a body, which they do, for example, in designs when the compressor is directly mounted on the engine. In such designs, the platform (compressor) could be fully supported by the engine. Due to the load (weight) of the engine block, this is often not possible, which means that the platform must be placed separately from the engine. 10 15 20 25 30 4 When the auxiliary system is placed separately from the motor, it is important to prevent all harmful relative movements / rotations between them, and especially those that have the greatest negative effect on the belt tension and alignment.
    The object of the present invention is to eliminate, or considerably reduce, problems which arise partly due to variations in the direction of the crankshaft relative to the rotating shaft of an auxiliary system to be driven, and partly due to variations in the tension of the belt. The problems are caused by the motor and the auxiliary system (eg an A / C compressor) being able to move independently of each other - except in the Y-direction (see eg figure 1).
    Summary of the Invention The above objects are achieved by the invention defined by the independent claim.
    Preferred embodiments are defined by the dependent claims.
    The present invention relates to a link arrangement in connection with a belt driven auxiliary system coupled to an internal combustion engine where the auxiliary system is coupled via a belt driven by the crankshaft of the internal combustion engine. In particular, the invention relates to a belt-driven system which is an A / C compressor and where the belt is a so-called V-belt.
    According to the invention, a link arrangement is arranged between the engine and the auxiliary system intended to prevent them from moving relative to each other in such a way that the drive belt wears and needs to be replaced prematurely.
    The present invention achieves the following advantages: Eliminates the impact on the belt of alignment variations caused by relative movement between the engine and the auxiliary system, which results in an increased life of the belt. v Reduced risk of belt tension varying, leading to increased GV belt life. 10 15 20 25 30 Brief description of the drawing Figure 1 shows a motor and a compressor driven by a drive belt according to the prior art.

    Detailed Description of Preferred Embodiments of the Invention In the detailed description, reference will be made, for example, to those illustrated in the accompanying figures. In the figures, the same reference numerals have been used to denote the same or similar objects.
    The following is an enumeration regarding movements and rotations in different directions and how they affect the direction and belt tension: In the figures, the different directions have been indicated by arrows and markings. 1. Movement in the X-direction. The effect on the alignment increases when the distance between the pulleys decreases. Small effect on the belt tension. 2. Movement in the Y-direction. Great effect on the belt tension. No effect on orientation. Prevented by a bar, as described above. 3. Movement in the Z direction. Small impact, especially when the distance between the pulleys is large. May cause slipping, but does not affect alignment. 10 15 20 25 30 6 4. Rotation around the X-axis. Small effect on the belt tension, but can cause slipping, but does not affect the alignment. 5. Rotation around the Y-axis. Great impact on the focus. Do not become fixed in relation to each other with a rod according to the solution shown in figure 2.
    Small effect on the belt tension. 6. Rotation around the Z axis. Great impact on the focus. Do not become fixed in relation to each other with a rod according to the solution shown in figure 2.
    Small effect on the belt tension.
    In order to significantly improve the service life, the movements / rotations in points 1, 5 and 6 need to be prevented (fixed), in addition to point 2 which is already prevented by the first rod 3 (see figure 2). This will require a different type of connection between the bodies.
    Figure 3 illustrates how an improved connection between the engine and the auxiliary system can be achieved. The coupling has been improved by inserting an additional rod 9 which has an oblique direction in the plane defined by the X and Y directions.
    The link arrangement shown in Figure 3 prevents relative movements in the X-direction and in the Y-joint.
    The coupling shown in figure 3 entails the following: 1. Movement in the X-direction. Fixed by the other bar 9. 2. Movement in the Y-direction. Fixed by the first bar 3. 3. Movement in the Z direction. Small impact, especially when the distance between the pulleys is large. May cause slipping, but does not affect alignment. 4. Rotation around the X-axis. Small effect on the belt tension, but can cause slipping, but does not affect the alignment. 5. Rotation around the Y-axis. Great impact on the focus. Do not become fixed in relation to each other with a rod according to the solution shown. Small effect on the belt tension. 10 15 20 25 30 7 6. Rotation around the Z axis. Great impact on the focus. Do not become fixed in relation to each other with a rod according to the solution shown. Small effect on the belt tension.
    To achieve fixation that has an effect on points 5 and 6, an additional link (rod) must be inserted.
    The present invention relates to a link arrangement intended to provide this fixation which also has an effect for points 5 and 6 above. The invention will now be described in detail, inter alia, with reference to Figures 4-8.
    The link arrangement 2 is intended to be used in connection with a motor 4 with a first shaft 6 provided with a first pulley 8, and an auxiliary system 10 with a second shaft 12 provided with a second pulley 14.
    A drive belt 16, preferably a so-called V-belt, is arranged on said first and second pulleys 8, 14 and adapted to transmit rotational movements from the first shaft 6 to the second shaft 12.
    The relative movements that can occur between said first and second axes 6, 12 have six degrees of freedom which are defined according to: an X-direction (X-axis) which is defined by the longitudinal direction of the first axis 6; a Y-direction (Y-axis) defined by a line intersecting said first and second axes at right angles, and which is perpendicular to the X-direction; a Z-direction (Z-axis) which is perpendicular to said X- and Y-directions, and rotation about the respective X-, Y- and Z-axis.
    The link arrangement 2 is adapted to be attached to the motor 4 and to the auxiliary system 10, respectively, and to prevent relative movements between said first and second axes 6, 12 in at least four degrees of freedom, these including rotation about the Y and Z axes, respectively. According to one embodiment, the linking arrangement 2 is adapted to absorb forces in an oblique direction in the plane defined by the X and Y directions and that the oblique direction does not correspond to either of the X and Y directions.
    Referring to Figures 4 and 5, two variants of an embodiment of the invention are shown. According to this embodiment, the linking arrangement comprises at least three elongate rod elements 18, 20, 22, each of which comprises two fastening parts 24, 26 adapted to be fastened to the motor 4 and to the auxiliary system 10, respectively.
    Two of the rod elements 18, 20 have a direction corresponding to the Y direction, and the third rod element 22 has an oblique direction which does not correspond to either of the X and Y directions. All rod elements 18, 20, 22 are substantially arranged in the plane defined by the X and Y directions.
    According to a further embodiment, the link arrangement 2 comprises a truss 28 which is schematically illustrated in figure 6. On two of the sides of the truss 28 at least two fastening parts 30, 32 are arranged which are adapted to be fastened to the motor 4 and to the auxiliary system 10, respectively. in Figure 6 should be seen as an example. The truss can be designed in many different ways and still absorb oblique forces in the Y-X plane. For example, the diagonal parts can be divided and supported by transverse parts. Figure 7 shows the linking arrangement mounted between a motor 4 and an auxiliary system 10. The other reference numerals have the same meaning as in the above description of figures 4 and 5. Figure 8 shows the linking arrangement shown in figure 7 from the side instead.
    A further variant may be to arrange two rod parts similar to those marked 18 and 20 in Figures 4 and 5 and then arrange a transverse rod part which connects the midpoints of the rod parts so that the link arrangement then resembles an H.
    For the rod parts and the truss it applies that the fastening parts 18, 20, 22, 30, 32 preferably comprise a ball joint and that the fastening parts are adapted to be fastened to the motor 4 and to the auxiliary system (10) via these ball joints. Alternatively, the fastening parts may comprise a hinge which allows movement in two dimensions, for example in the Y-Z plane of the truss 28 and of the rod members 18, 20.
    In general, for all embodiments, the link arrangement 2 is adapted to transmit movements from the motor 4 to the auxiliary system 10. The link arrangement is therefore rigid in the directions in which relative movements are to be prevented. This means, for example, that the rod element is primarily adapted to absorb forces in its longitudinal direction and is then made of a suitable material, for example a steel alloy, and has a dimension adapted to the forces in question.
    The present invention also relates to a vehicle, for example a bus or a truck, comprising an engine 4, an auxiliary system 10, preferably a compressor, and a link arrangement 2 as described above.
    The link arrangement according to the present invention and as exemplified in Figures 4-8 thus provides the following: 1. Movement in the X-direction. Fixed by the diagonal rod element 22, alternatively by the truss 28. 2. Movement in the Y-direction. Fixed by the rod elements 18 and 20. 3. Movement in the Z-direction. Small impact, especially when the distance between the pulleys is large. May cause slipping, but does not affect alignment. 4. Rotation around the X-axis. Small effect on the belt tension, but can cause slipping, but does not affect the alignment. 5. Rotation around the Y-axis. Fixed by the rod elements 18, 20, 22, alternatively by the truss 28. 6. Rotation around the Z-axis. Fixed by the rod elements 18, 20, alternatively by the truss 28.
    The present invention is not limited to the above-described preferred embodiments. Various alternatives, modifications and equivalents can be used. The above embodiments are therefore not to be construed as limiting the scope of the invention as defined by the appended claims.
