    The invention relates to a tensioning device for a tensioning mechanism, arranged on a combustion engine, which has a driving wheel arranged on a transmission shaft of an engine, one or more driving wheels and a means of traction, circulating continuously, which it involves the driving wheel and the other driving wheels. The tensioning device comprises two tensioning arms with tensioning wheels placed on them that exert tensioning force on the traction medium, in the direction of rotation, in front and behind the driving wheel and has a spring that generates the tensioning force and a tensioner housing, which reliably rests at least one tension arm, driven by the force of the spring.
    BACKGROUND OF THE INVENTION
    Especially in the case of tensioning mechanisms with drive wheels that alternately accommodate and generate torque and with the corresponding change of the traction branch and the loose part of the belt, the tensioning of the loose part of the belt requires a tensioning device with two tensioning wheels, which pre-tension the means of traction in front of and behind the drive wheel of the drive shaft that drives or is driven alternately. In the case of the transmission shaft, it is typically, but not necessarily, an engine shaft designed as a starter generator, which generates the torque for starting the combustion engine and receives the torque to generate electrical energy.
    While in the case of tensioning mechanisms, in principle, they can be driven by belts, chains or articulated belts, tensioning devices of the type mentioned above are typically known as belt tensioners in a belt drive system. auxiliary components in several construction variants. For example, tensioning devices are proposed in the patents DE 199 26 615 Al, DE 10 2008 025 552 Al and DE 10 2006 019 877 Al, which have, respectively, a housing fixed on the startergenerator and 5 two tension arms arranged in it in a movable way, on whose tension rollers a force is exerted by means of a spring arranged between them, to tension the belt. TASK OF THE INVENTION
    * Based on this, the task of the present invention is to improve the construction of a tensioning device of the type mentioned above, especially with regard to low complexity. SUMMARY OF THE INVENTION
    The solution to this is to provide a support for the tensioner housing on the motor, which rotates around the center line of the transmission shaft. In other words, the tensioner housing itself, which is accommodated in such a way as to rotate, participates in the tensioning movement and the necessary fixation of the tensioning device, in the state of the art mentioned, next to the engine and from there on the startergenerator or on a separate support for an auxiliary component it can be dispensed, favoring less constructive complexity. In addition, the mounting of the tensioning device on the belt drive system can be considerably simplified if the tensioning device and - the drive wheel are joined __. screwed together on the transmission shaft.
    In a preferred arrangement of the invention, the tensioner housing must be supported by means of a bearing, 30 on the drive shaft or the drive wheel. The considerably low friction of the bearing compared to a sliding support does not provide a support that resists fatigue and low friction of the tensioning device on the rotational drive shaft or the rotating driving wheel, but also comes with correspondingly low damping of the device tensioner in the oscillating movements of the tensioner housing. The tensioning device according to the invention, for this reason, is not only suitable for tensioning traction media with alternating traction branches and practically static voids, but can also be used in a dynamic coupling of the generator of the uniformities of 10 combustion engine rotation. Because, due to the dynamic oscillation movement of the connected tensioning device almost free of damping in the generator, a balance of moments appears in the tensioning device around the axis of the generator. In this way, the oscillations of the traction medium generated by the rotation uniformities are reduced.
    In the case of the support on the driving wheel, it is especially advantageous if the tensioning device forms a structural unit, which can be mounted on the drive shaft, with the driving wheel and the bearing, which is inserted in a recess 20 in the shape of a wheel ring. drive, radially between a support section of the tensioner housing, which runs through the recess, and a drive wheel hub. As mentioned above, the advantages are given, on the one hand, by the very simplified assembly of the tensioning device and, on the other - because of the components fitted together - by their construction, in the radial direction _ of the _ axis of _ extremely compact transmission. If, in addition, the bearing and the external perimeter of the driving wheel, involved by the means of traction, travel in the same transmission plane, the disengagement moment of the tensioning device will be minimized, in its support point, with disengagement loads. correspondingly low. The fixation of the bearing in relation to the drive wheel and the support section of the tensioner housing can be carried out, in the known way, by means of pressure fitting, an axial retaining ring or both.
    As an alternative to the tensioner frame support on the drive shaft or the drive wheel, the (immobile) support can also be made on the motor housing, for example, on a pin that runs behind the drive wheel. This support can be carried out either as a bearing or a bearing, and in the case of the bearing, if necessary, a friction adjusted to a defined value with comparatively greater cushioning can also be provided.
    In order to simplify the construction, the tensioner housing must, in addition, accommodate only one of the tensioning arms in a mobile way and the other tensioning arm must be fixed inside or in the tensioner housing. In the preferred case in which, in the case of the engine, it is a startergenerator of the combustion engine, the tensioner wheel of the arm, movably received, must be arranged in front of the driving wheel, in the direction of rotation of the means of traction. During the operation of the generator, the tensioning wheel of the mobile arm is applied only to tension the loose part of the belt. As a result, the risk of self-locking on the support of the movable tension arm and loads can be reduced.
    However, on the contrary, it can also be advantageous, especially in the case of a startergenerator belt drive system, the arrangement of the tension wheel fixedly received in the tensioner housing in front of the driving wheel, in the direction of belt rotation . With this arrangement of the tensioning wheels, the risk of falling from the part of the belt that runs on the driving wheel of the startergenerator, which is linked to a more noticeable acoustics and greater wear, is clearly less than in the arrangement of the tensioning wheel mentioned above. For, in the case of the tensioning wheel fixed to the tensioner housing, there is no gap between the tensioning arm and the tensioning wheel, which could favor the fall of the belt.
    For the alternative case, in which the two tensioning arms 5 are movably accommodated in the tensioner housing, a relative movement can be distributed between the tensioning arm and the tensioner housing in both tensioning arms and, for this reason, the wear load on the support parts of the tension arms can be reduced.
    The tensioning arm, which is movable, must have a support part in a circular arc shape, the spring must also be projected in an arc and the tensioner housing must have a corresponding circular arc shape channel, in which, the support part of the tensioning arm 15 and the arc spring are moved in a circular manner by the mobile arc. The tension arm, the channel and the arched spring should preferably run concentric to the center line of the transmission shaft. An arch spring means, as is well known, a compression screw spring, curved in an arc shape, in its longitudinal direction. Especially for the case where the tensioner housing moves the two tensioning arms in a mobile way, one or two support parts of the tensioning arms can have the shape of a hollow cylinder and accommodate, in order to favor the use of the longest possible spring length with a correspondingly lower spring stiffness.
    In order to offer protection against wear, the circular arc shaped channel must be covered, at least, in the radial external direction of the spring in 30 arc, with one or more sliding parts. Advantageously, the channel can also be provided with sliding parts on the support part of the tensioner arm / s. By choosing the material or combination of materials, the desired friction / damping between the tensioner housing and the tension arm as well as between the tensioner housing and the arc spring can be adjusted.
    The tensioner housing can comprise, favoring a simpler fabrication and assembly, two curved halves connected together, forming the channel and, preferably, having a shape approximately or completely in mirror symmetry. With regard to low production costs, curved halves are foreseen as parts made of sheet metal or - in favor of a comparatively small moment of inertia around the rotational axis - as injection-molded plastic parts. The support part for accommodating the tensioner housing in the motor can be manufactured as a separate part and joined with the curved halves or be molded in one piece together with one of the curved halves. Alternatively, it is also possible to have a tensioner housing with a pipe-shaped channel, made integral and, according to the structure of the support part, it can be thought of as a structure in one part or more parts. The concept of junction should cover all known methods for establishing junction connections. SHORT DESCRIPTION OF THE FIGURES

    Figure 1 shows partly schematically the arrangement of a tensioning mechanism of a combustion engine designed as a belt drive system of 20 auxiliary components 1. The traction medium, designed here as multiple V-belts 2, which runs continuously on the direction of rotation indicated by the arrow, involves the driving wheel 3 of an engine designed as startergenerator 4 and two other driving wheels 5 and 6, which are arranged in the combustion engine crankshaft or in an A / C compressor.
    The crankshaft gear 5 is activated, in a known way, to start the combustion engine in the startergenerator 4 start mode, and then, with the combustion engine started, start the startergenerator 4 in the 30 generator mode. The drive wheel 3 that alternately generates or receives the torque generates a synchronous change to this from the traction branch to the loose part of the belt in the startergenerator 4. In the starting operation of the combustion engine, the branch 7, which runs in the direction of rotation , in front of the driving wheel 3 that drives the crankshaft gear, is the traction branch, and the branch 8, which runs in the direction of rotation, behind the driving wheel 3, is the loose part of the belt. In contrast, in generator mode, branch 7, which runs in the direction of rotation, in front of the driving wheel 3 driven by crankshaft gear 5, is the loose part of the belt, and branch 8, which runs, in the direction of rotation, behind the driving wheel 3, is the traction branch. As mentioned initially, the tensioning of the alternately loose part of the belt requires a tensioning device with two tensioning wheels 9 and 10, which exert tensioning force on the belt 2, in its direction of rotation, in front and behind the driving wheel 3. The structuring of a tensioning device 11 according to the invention, which is arranged on the driving wheel 3 of the startergenerator 4, according to figure 1, is explained below, based on figures 2 to 9.
    Figure 2 shows a perspective view on the front side of the tensioning device 11, which faces the other side of the startergenerator, and figure 3 shows the tensioning device 11 in explosive representation, where, for a better illustration, the curved half upper part of the tensioner housing 12, shown in figure 3 with 12a, has been removed in figure 2. The two tensioning wheels 9 and 10 are screwed by means of a bearing, not shown in detail, with the corresponding tensioning arms 13 and 14, of which, one tension arm 13 is movably arranged on the tensioner housing 12 and the other tension arm 14 is fixed on the tensioner housing. The tensioning wheels 9, 10 are positioned on the belt drive system 1, according to figure 1, in such a way that the tensioning wheel 9 of the tensioning arm 13, movably received, is arranged in front of the driving wheel 3, in the direction of rotation of the belt 2.
    The tensioner housing 12 comprises the upper curved half 12a and another lower curved half 12b facing the startergenerator 4. The curved halves 12a, 5 12b, symmetrically identical, which are manufactured from a sheet metal, and axially joined one in the another by means of welding, they are molded in such a way as to form, inside the housing of the tensioner 12, a closed channel in the shape of a circular arc. A spring, correspondingly curved, in 10 arc spring format 16 and a support part 17 of the tensioning arm 13 movable, in a corresponding circular arc shape, are movably received in channel 15, concentrically to the driving wheel 3 and in the direction of the circular arc. The channel 15 is covered in the radial external direction of the arc spring 16 with a sliding part and here with a sliding sleeve 18 with a cross-section in a semi-circle. The sliding sleeve 18, manufactured by means of polyamide injection, applies not only as protection against the wear of the arc spring 16, but also has a defined behavior with the appropriate combination of plastic / surface material of friction / damping, in the relative movements between the arc spring 16 and the tensioning housing 12. For the same reasons, the support part 17 of the movable tensioning arm 13 is also included in the sliding parts 19 and 20 of polyamide, similar to a clamp, which are formed by two pairs of two identical halves of clamp 19a, 19b and 20a, 20b and whose circumferential position in channel 15 is another parameter that can influence, in a determined way, the friction / damping behavior in the movements between the tension arm 13 and the tensioner housing 12.
    The sliding parts 19, 20 stand out in the enlarged illustration of figure 8a, with the clamp halves 19a, 19b and 20a, 20b corresponding to the bone-shaped molding, in cross-section, of the support part 17 according to figure 8b. Compared to a circular cross-section 5, it can be reduced, through this molding, a twist of the tension arm 13 around its curved longitudinal axis and, consequently, of the tension wheel 9 around its rotational axis, especially if the tensioner arm 13 is extended widely, outside the housing of tensioner 12 and whose lifting arm, which prevents positively twisting in the housing of tensioner 12, is correspondingly small. As a crossing angle, an angle of 20 ° is provided, which results from the support of the cylindrical spring support 21 in the support part 17 in the complementary shape, that is, convex of the curved halves 12a and 12b. This is evident from figures 5 and 7 with the curved halves 12a, 12b shown in enlarged form.
    The fixing of the sliding sleeve 18 and the sliding part 19, 20 in the tensioner housing 12 is carried out 20 by means of positive locking by means of axially shaped noses, which fit together, as shown in figures 5, 6, 7 and 8a, in the recesses or openings. Thus the noses of the sliding parts 19, 20, uniformly identified with the reference number 22, fit into the 25 openings of the curved halves 12a, 12b, uniformly identified with the reference number 23, and the noses of the sliding sleeve 18, uniformly identified with the reference number 24, fit the openings of the curved halves 12a, 12b, identified uniformly with the reference number 25.
    From figures 5 and 7 together with figure 9, it can also be seen that the tensioner arm 14 attached to the tensioner housing 12 has a fixing pin 26, I which is introduced into a tubular protrusion formed by semi-cylinders 27a and 27b of the two curved halves 12a and 12b and at the same time it is protected on the protrusion against turning by means of noses 28. The two tension arms 13, 14 5 are produced as aluminum pressure molding parts.
    As can be seen from figures 3 and 4, the tensioner housing 12 is housed on the drive shaft 30 of the startergenerator 4 so as to tilt around 10 around it. In the concrete structure, a bearing for the form of a grooved ball bearing 31 is provided, which houses a support part 12c of the tensioner housing 12 in relation to a driving wheel 3 screwed with the drive shaft 30. It is only 15 The threaded hole 32 of the drive shaft 30 for the central screwing of the driving wheel 3 is shown, which is not shown but is already known.
    The tensioning device 11 forms, with the driving wheel 3 and the ball bearing 31, a structural unit that can be mounted on the drive shaft 30 in an extremely easy way, which only needs to be fixed to the central screw on the startergenerator 4. As can be observed in figures 5, 6, 7 and 8a, the structural unit can be delivered to the assembly station, in the pre-tensioned state of the spring in 25 arc 16, with the movable tensioning arm 13 fixed, in the direction of rotation, on the housing tensioner 12 by means of a safety pin (not shown) going through the perforations 33 in the curved halves 12a, 12b and the perforation 34 in the tension arm 13. 3 0 With a new reference to figures 3 and 4: how the two curved halves 12a , 12b, the support part 12c of the tensioner housing 12, which is joined by its front side with them and also welded here, is manufactured from a metal plate with a cylindrical projection 35, which runs concentrically in a recess 36 in shape of drive wheel ring 3. Ball bearing 3 is inserted radially by means of a pressure fitting. By arranging the components that fit together, the ball bearing 31 and the outer perimeter of the driving wheel 3, which is surrounded by the belt, run in a common driving plane. Consequently, in addition to the particularly compact axial construction method, the disengagement moment of the tensioning device 11, at its support point, with correspondingly low disengagement loads of the ball bearing 31 is minimized.
    The support according to the invention of the tensioning device 11, with a change of loads in the drive system 15 by belt 1, caused by the momentary operating mode of the startergenerator 4, that is, in the switching of the traction branch to the loose part of the belt, has the effect of deflecting the tensioner housing 12 on the statergenerator 4 around the center line of the drive shaft 29. In the case of the present example of execution with only one movable tension arm 13, for example, a transmission of forces occurs, which causes the rotation deviation, through the tensioning wheel 9, of the tensioning arm 13, the arc spring 16, the tensioner housing 12 and the fixed tensioning arm 14 until the tensioning wheel 10. An optimization of the rotation movement 25 can be achieved by means of friction parameters, which can be adjusted independently of each other, on the bearing 31 and on the tribological pairs between the movable tension arm 13 and the arc spring 13 and, on the other hand, and on the tensioner housing 12, by 30 or tro.
