Definitions
- the present invention relates to a traction mechanism drive for a starter generator concept of an internal combustion engine.
- the traction mechanism drive comprises a first belt pulley arranged on the crankshaft of the internal combustion engine, a second belt pulley connected to the starter generator and a tensioning system with which a tensioning of the traction strand and the empty strand of the traction mechanism drive can be achieved.
- the starter generator is a unit with which, depending on an operating mode, the internal combustion engine is started, or electrical energy can be obtained while the internal combustion engine is running.
- the starter generator thus takes on both the function of the starter and that of a generator.
- a torque is introduced from the starter generator or the internal combustion engine into the traction mechanism drive. This is associated with a change in the empty run and the pull run in the traction mechanism drive. Due to the mutually directed torque, the tensioning system requires two pulleys, which preload the respective empty run of the traction device with sufficient spring tension.
- a traction mechanism drive with a tensioning system which comprises two tensioning rollers, which are assigned to an empty strand or a tension strand, is known from the published patent application JP 90 144 821 AA.
- the structure of the known traction mechanism drive comprises two equally dimensioned pulleys, a drive pulley and an output pulley, which are connected via a traction mechanism to a belt.
- the tensioning system consisting of a straight-line holder with pulleys arranged at the ends, is fixed in the center. Of the pulleys symmetrically attached to the end of the holder, one is assigned to the tension strand and the other pulley to the empty strand.
- the present invention is based on the problem of realizing a tensioning system for a traction mechanism drive, which ensures sufficient tensioning of the traction mechanism regardless of the direction of the torque introduced into the traction mechanism drive.
- the aforementioned task is solved according to the invention by a tensioning system with which the traction means wraps around the two pulleys of the tensioning system with mutually different wrap angles, regardless of the direction of the torque introduced into the traction mechanism drive.
- the tensioning system according to the invention thus also ensures a sufficient pre-tensioning of the respective idle strand for a starter generator concept - in which a change of direction of the torque introduced into the traction mechanism drive occurs depending on the operating mode.
- the clamping system thus fulfills two independent functions that are necessary for a starter generator concept.
- the reaction of the tension pulley located in the empty strand to the tension pulley arranged in the tension strand takes place in such a way that a deflection of the pulley, which is assigned to the tension strand, applies a corresponding counter-torque, in order to increase the supporting force of the pulley assigned to the empty strand.
- This interaction is favored by the pulleys of the tensioning system arranged on torsionally rigid lever arms.
- the combined tensioning system according to the invention consequently enables simultaneous pretensioning of the empty run and the pull run, regardless of the direction of the torque introduced into the traction mechanism drive.
- This tensioning system is therefore preferably suitable for a starter generator concept which ensures sufficient tensioning of the traction means even when the torque changes between the starting mode and normal mode.
- the tensioning system according to the invention in conjunction with a guide of the traction means, which has different wrap angles on the pulleys, together reinforces the desired influencing or reaction between the two pulleys, for improved pretensioning of the respective traction means strand.
- wrap angle of the traction means on the pulleys are designed so that in normal operation the belt pulley assigned to the empty strand loops or compensates for more belt length released during a pivoting movement of the tensioning system than the further, the Release belt assigned pulley of the tensioning system at belt length.
- a desired increase in the tension force in the empty run can thus be achieved, which has a positive effect on the slip behavior of the entire traction mechanism drive.
- the tensioning system according to the invention is designed in a start-up mode so that the pulley assigned to the train strand is aligned with a dead center position.
- the direction of a resulting tensile strand force largely coincides with a direction that corresponds to a connecting line between the axis of rotation of the tensioning system and the axis of rotation of the pulley lying on the tensile strand.
- the lever arm of the tensioning system assumes a position in which the resulting tensile strand force has no effective lever length.
- a changing tensile strand force has no influence on the displacement of the tensioning system. This effect occurs when the resulting strand tension runs parallel to or in the plane that corresponds to an imaginary connection between the pivot point of the tensioning system and the pivot point of the pulley supported on the strand.
- the wrap angles of the belt on the respective pulley also differ.
- the pulley which is supported on the tensioning system with the shortest lever arm, has the largest wrap angle of the belt.
- the other pulley of the tensioning system which is in contact with the empty run in the start mode, has a small wrap angle of the belt.
- the belt pulley which loops a longer belt length, affects the further belt pulley, which is consequently supported on the belt with an increased pretensioning force.
- the invention further includes measures for designing the tensioning system, with which the prestressing force of the traction means can be influenced in a targeted manner.
- a preferred embodiment provides that in the starting mode, a first distance between the axis of rotation of the tensioning system and a directional arrow, which defines the resultant force of the idler pulley and passes through the center of rotation of the pulley, is obtained, which exceeds a second distance that exceeds the distance between the axis of rotation of the Tensioning system and a directional arrow that defines the resultant force of the tension strand and that passes through the center of rotation of the pulley.
- a further embodiment of the invention provides that in starting operation, the pulley assigned to the empty run is supported on the traction means in such a way that a max. Sets the distance between the axis of rotation of the tensioning system and the directional arrow of the resulting empty strand force.
- the max. Distance measure exceeds the further distance measure that is established between the axis of rotation of the tensioning system and the directional arrow of the resulting force of the tensile strand in the area of the pulley. This measure enables a high pretensioning force of the traction device and thus ensures a slip-free drive, i.e. a safe start of the internal combustion engine.
- An advantageous embodiment of the invention relates to a traction mechanism drive in which the traction mechanism, starting from a first pulley of the tensioning system, encloses the pulley of the starter generator before of the traction device reaches the second pulley of the tensioning system.
- This traction device guide ensures sufficient pretensioning of the traction device required for the function of the starter generator by the tensioning system independent of the operating mode of the starter generator, ie the direction of the torque introduced into the traction device drive.
- the tensioning system according to the invention is further provided with an effective spring means, which ensures a prestressed, spring-loaded contact of the pulleys of the tensioning system on the traction means.
- the invention includes different spring means.
- the clamping system can be coupled with a hydraulic or a mechanical spring.
- the spring means can act directly on a lever arm of the clamping system or, alternatively, act on a hub of the clamping system in the region of the axis of rotation.
- the invention also includes a clamping system with a combined mechanical-hydraulic spring means.
- the function of the tensioning system according to the invention also requires a damping device which ensures effective damping, in particular with respect to torque and / or speed fluctuations of the traction mechanism drive.
- the damping device ensuring largely shock and shock-free traction means guidance can be arranged separately from the spring means or combined with the spring means to form a spring damping unit.
- Advantageous further refinements of the invention relate to the geometric arrangement or dimensional relationships of the lever arms of the tensioning system. It is preferable to arrange the lever arms of the tensioning system at an angle of> 70 ° to one another. A ratio that is suitable for the length of the lever arms provides that the longer lever arm exceeds the shorter lever arm twice.
- Another design criterion of the tensioning system according to the invention relates to the diameter of the pulleys. Thereafter, the diameter of the pulley arranged on the longer lever arm exceeds the diameter of the pulley arranged on the shorter lever arm.
- the invention naturally extends to differently designed clamping systems, in which the lever arms are arranged at an angle deviating from> 70 °, or the lever arms are designed in a different length ratio.
- the invention also includes tensioning systems whose pulleys are provided with the same diameters, for example.

- Figure 4 shows the clamping system according to Figure 2, provided with a
- the traction mechanism drive 1 a shown schematically in FIG. 1 is provided with the tensioning system 2 according to the invention, which ensures sufficient tension of the traction mechanism 3, a belt, even when the torque changes in the traction mechanism drive 1 a.
- the clamping system 2 comprises two pulleys 4, 5 which are arranged at the end on lever arms 6, 7, which are attached to a hub 8 rigidly offset from one another. The entire clamping system 2 can be pivoted about an axis of rotation 9 arranged centrally in the hub 8.
- the traction mechanism drive 1a provided for an internal combustion engine serves to drive various units of the internal combustion engine.
- the traction device 3 connects the individual pulleys of the units.
- the traction mechanism drive 1 a also extends to the starter generator 12, which unites the starter and the generator in one structural unit in comparison to conventional internal combustion engines.
- a torque is introduced into the traction mechanism drive from the starter generator 12 or the internal combustion engine. H.
- the direction of the torque changes between the start and normal operation.
- such a traction mechanism drive 1 a requires a tensioning system 2 with which the respective empty strand is sufficient, ie. H. is slip-free, especially in the area of the starter generator 12.
- the pulley 4 is assigned to the pull strand 10 and the further belt pulley 5 to the empty strand 11.
- the pulleys 4, 5 are supported at an angle> 70 ° offset on the traction means 3.
- the pulley 4 is located near a dead center position, in which this pulley 4 performs the function of a deflection roller for the tensile strand 10.
- a distance measure (l 2 ) is defined by the direction of a resulting force indicated by the directional arrow, the tensile strand 10 in the area of the pulley 4 and the axis of rotation 9 of the tensioning system 2.
- the position or the arrangement of the belt pulley 4 in the start mode means that a changed tensile force has no influence on the further belt pulley 5 of the tensioning system 2.
- the pulley 5 of the tensioning system 2 is supported on the empty strand 11 with a longer distance dimension () than the pulley 4.
- the resulting force of the empty strand 11, indicated by the directional arrow, is oriented so that it uses the lever arm () which largely corresponds to the maximum length of the lever arm 7 of the clamping system 2.
- the moment equilibrium is characterized almost exclusively by a spring torque or by a spring force of a spring means, translated to the corresponding distance dimension and the force of the empty strand 11 effective on the distance dimension (H).
- the wrap angle "oc” with which the traction means 3 wraps around the pulley 4 is greater than the wrap angle "ß" of the pulley 5.
- the wrap angles, "" and “ß” also determine the belt lengths wound up by the pulleys 3, 4 and affect the belt pretension. Because of the smaller wrap angle " ⁇ ", the pretensioning force in the empty strand 11 of the traction means 3 can be achieved by applying a slight pretensioning of the tensioning system 2.

- the further pulley 5 of the tensioning system 2 is supported on the tension strand 12 and is loaded with the drive torque of the generator, which leads to a pivoting movement of the tensioning system 2 in the counterclockwise direction.
- the distance dimension (li) is reduced and at the same time this movement leads to an increase in the distance dimension (l 2 ) of the belt pulley 4.
- An increased distance dimension (k)> 0 causes a restoring force by the tensioning roller 4 on the further tensioning roller 5 of the tensioning system 2.
- a moment equilibrium is reached by the spring moment or by the spring force of the spring means, translated to the corresponding distance measure, ie the resulting force of the tensile strand 10 effective on the distance measure (l 2 ) and the force acting on the distance measure (li) of the empty strand 11.
- the wrap angles " ⁇ , ⁇ " of the traction means 3 on the pulleys 4, 5 also differ.
- the smaller wrap angle “ ⁇ " on the pulley 5 enables an increased pretensioning force of the traction means 3 in the empty strand.
- the wrap angle “ ⁇ , ⁇ ” is designed in normal operation in such a way that the pulley 4 loosens the length of the traction means 3 that is released than the pulley 5 exposes at the traction means length.
