Definitions

  • the invention relates to a torsionally flexible coupling with different coupling elements for a multi-stage torque transmission between drive and output side, at least one first coupling element for a first coupling stage in a lower load range and the further coupling elements for at least one further coupling stage in a higher one Load range are provided.
  • At least one rubber element vulcanized on the drive and output side is provided for the first clutch stage, and in that the further coupling elements are matched to the at least one rubber element in such a way that they start from a defined load range of the at least one rubber element be effective.
  • the advantages of the vulcanized rubber elements known per se are thus taken over, namely in particular a defined behavior at the zero point and no point of discontinuity when the direction of rotation changes.
  • the other coupling elements are also suitable for high load ranges, so that the two-stage or multi-stage coupling according to the invention covers a wide range of performance.
  • the at least one rubber element and the coupling elements of the further coupling stage are arranged at the same axial height - based on the coupling axis - but spaced apart from one another in the circumferential direction.
  • the coupling has a relatively small axial length.
  • the tension elements are radially preloaded in the unloaded state.
  • the force transmission through the tension elements starts at lower angles of rotation, so that the transition between the first and second clutch stages and, in particular, the start of the force transmission through the tension elements does not occur suddenly, but gently.
  • highly stable tapes or ropes in particular made of steel, are provided as tension elements. This further increases the performance of the coupling, since the tension elements can also be used for very high load ranges.
  • FIG. 1 shows a section of a front view of a first embodiment of a two-stage clutch according to the invention, in which the different clutch elements are arranged essentially in a common radial plane,
  • FIG. 2 shows a section through the coupling according to FIG. 1 along the section line II-II in FIG. 1,
  • FIG. 3 shows a further section through the coupling of FIG. 1 along the section line III-III in Fig. 1, and
  • the coupling (1) has an annular coupling flange (3) which is fixedly connected to suitable elements of the output side which are not shown in detail.
  • the drive-side coupling hub (2) and the driven-side coupling flange (3) are connected to one another by various elastic coupling elements (5-, 6), all elastic coupling elements (5, 6) on the one hand on the coupling hub (2) and on the other are attached to the coupling flange (3) and extend essentially radially outwards between the coupling hub (2) and the coupling flange (3).
  • the coupling elements serve on the one hand two diagonally opposite elastic disc segments (6), which are made of rubber, with respect to the longitudinal axis (4). Radially on the inside, each of the two rubber disc segments (6) is vulcanized onto an inner metal part (7) and an outer metal part (8).
  • the metal part (7) is firmly connected to a radial flange segment of the coupling hub (2) by means of an arc-shaped fastening flange and a plurality of screw connections (9).
  • the upper metal part (8) is connected to the coupling flange by means of analog screw connections (9), which are not shown in the drawings
  • the coupling elements (5) are arranged, which represent tab elements (5) serving as tension elements.
  • the arrangement of such tab bodies (5) as elastic coupling members is already known from DE-OS 25 10 197.
  • Each tab body (5) has a diamond-like shape (FIG. 1) and is provided at its upper and at its lower end with a metal receiving sleeve penetrating the tab body (5) axially parallel to the coupling axis (4).
  • the flap bodies (5) are themselves made of rubber and reinforced by means of additional fabric inserts. As a result, the flap bodies (5) have a considerably higher load capacity than the rubber disk segments (6).
  • the link bodies (5) are also considerably more torsionally stiffer than the rubber disk segments (6).
  • Each tab body (5) is connected to two radial flange parts of the coupling hub (2) by means of a bolt (10) pushed through the receiving sleeve.
  • a metal flange (12) fastened on the output side also has two radial flange attachments, on which the upper end of each bracket body (5) is held by means of a bolt (11) pushed through the upper receiving sleeve.
  • the flap body (5) can be pivoted within certain limits about the longitudinal axes of the two bolts (10 and 11), so that the flap body (5) also has a certain degree of torsional flexibility.
  • the coupling (1) per quarter circle segment is shown in the illustration In the exemplary embodiment, two tab bodies (5) are provided, so that the coupling (1) has a total of four tab bodies (5) and two rubber disk segments (6).
  • the tab bodies (5) and the rubber disc segments (6) are matched to one another in such a way that, for a lower load range, initially only the rubber disc segments (6) are effective and when the clutch (1) is started up from idling, the tab bodies (5) gradually become effective, in particular for power transmission in high load ranges.
  • tab bodies and rubber disk segments are also in a row, i.e. arranged essentially in a common radial plane.
  • the rubber disk segments are of narrower design, so that a total of four rubber disk segments are used.
  • a rubber disk segment and a tab body are alternately arranged one behind the other in the circumferential direction.
  • rubber disk segments (6) and, on the other hand, tab bodies (5) are arranged as coupling elements between the drive side and the driven side.
  • the tab bodies (5) and the rubber disk segments (6) are open the coupling axis (4) - axially spaced one behind the other.
  • the coupling hub (2a) is provided with an axial attachment (14), which also increases the axial length of the receiving bore (13a).
  • the corresponding lower metal part (7) is provided with a radially downwardly protruding attachment lug, which with the aid of Screw connections (16) are fastened to a radially oriented disc (15), which in turn is fastened to the axial shoulder (14) of the coupling hub (2a) with the aid of screw connections.
  • the rubber disk segment extends over the entire circumference of the clutch (1), so that it represents a disk ring encircling the entire circumference.
  • this exemplary embodiment would also correspond exactly to the representation according to FIG. 4.
  • the different coupling elements are arranged axially one behind the other. The operation of this clutch corresponds to the clutch (1) according to FIGS. 1 to 3.
  • the different clutch elements (5 and 6) create a two-stage clutch, the rubber disk segments (6), or a corresponding disk ring, being provided for a first clutch stage in a lower load range for power transmission .
  • the torsionally stiffer tab bodies (5) which are much more resilient due to their fabric inserts, are used for the second clutch stage, so that the tab bodies (5) become effective from a certain load range in addition to the rubber disk segment stage already claimed.
  • the second clutch stage formed by the tab bodies (5) is added from a certain load range prevents overloading of the first clutch stage, namely the rubber disk segments (6), since the rubber disk segments (6) are caused by different rotation between the drive side and the driven side are only subjected to thrust until the tab bodies (5) become effective.
  • the tab bodies are further stabilized in that they are designed as highly stable tension elements in the form of steel strips or steel cables.
  • bodies are combined with highly elastic rubber washers or rubber washer segments, as in the illustrated embodiments.
  • the tab bodies (5) for the second clutch stage are replaced by alternating claw elements arranged on the drive and output side, which come into positive engagement with one another in the circumferential direction as soon as a defined load range when the clutch is raised from the Idle reached.
  • elastic pressure bodies are provided between the adjacent and operatively connected claw elements on the drive or on the output side, which press the claw elements against each other and thus the start of the power transmission between the drive side and Steam output side.
