Definitions

  • the tensioning device has a means for controlling and / or regulating the belt tension as a function of at least one detected parameter representing a measure of the belt tension.
  • the belt tension can be controlled as a function of the pulley speed.
  • Each speed or a predetermined speed range is assigned a specific belt tension, which is automatically set by the tensioning device.
  • the high belt pretensioning force level required at higher speeds can be achieved, and the belt pretensioning force can also be reduced in the area of the idle speed, so that toothed belt noises do not even arise at this very important operating point.
  • the tensioning device 1 has a tensioning roller 2, on the outer running surface of which a belt (not shown) is guided.
  • This belt is connected to a further drive pulley, also not shown, driven by a crankshaft.
  • the belt drive comprises further pulleys or pulleys, which can be connected to a camshaft and ancillary units.
  • the tensioning roller 2 shown in FIG. 1 is located between two other rollers of the belt drive and serves to influence the belt tension and to generate a belt pretensioning force.
  • the base plate 5 is shown.
  • the base plate 5 has a circular opening in its center, which enables the base plate 5 to rotate.
  • the leg spring is a torsion spring, the axis of rotation of which coincides with the center of the adjusting eccentric 4 shown in FIG. 1.
  • the leg spring is supported on the one hand on the fastening point 7 of the base plate 5 and on the other hand on the working eccentric 12 shown in FIG. 4.
  • a permanent torsional moment acts on the work eccentric 12, which leads to a tracking of the work eccentric 12 and the tensioning roller 2 when the belt is stretched, so that the belt tension can be kept approximately constant.
