  • the inventive flexible, deflectable tension member has the following main advantages even without optical or electrical conductors:
  • the material fatigue lasts twice as long as with conventional ropes of the same cross section and the same structure, the minimum bending radius is much lower.
  • the losses in tensile strength with age are up to about 20% lower.
  • the friction / tensile behavior is determined by the composition of the outer coating and its texture or surface roughness.

In the core area thinner, wire-shaped individual elements 10 are neither coated nor kept at a distance. Essential is the distance between the eight outer wire-shaped individual elements 10 from each other.
  • the strand 18 according to FIG. 4 can be used separately as a tension member 16, but can also be stranded with other strands 18 or otherwise combined to form a multi-shaped tension member 16. 5, this is illustrated by means of a straight band-shaped tension member 16, eight strands 18 according to FIG. 4 or one of the following FIGS. 5 to 17 are embedded in a thermoplastic material 26. According to embodiments not shown, the band-shaped tension member according to FIG. 4 may also be arched or serpentine with respect to the cross section.
  • the strand 18 shown in FIG. 6, which can be used as a tension member 16, differs from that of FIG. 5 in that the inner individual elements 10 of a smaller wire diameter are completely coated with a thermoplastic material 12. As a result, the strands 18 used individually or in combination gain further flexibility.

  • the middle and inner layers of individual elements 10 are also arranged in the core layer 34 at a peripheral distance. This results in increased flexibility. Furthermore, the material fatigue can be delayed.
  • the outermost layer of individual elements 10 is also held only in the inner layer 32 at a peripheral distance and fixed by adhesion.
  • the outer and inner layers 20, 32 do not bind to each other, and therefore an adhesion layer 36 is interposed therebetween.
  • the essential distance of a portion of the individual elements 10 for the outermost layer is by far the most significant, it is advantageous to also keep the inner layers of individual elements at a distance, e.g. in a coating of the individual elements 10 and / or the arrangement of filling material. Not shown in FIG. 12, it may therefore be advantageous for corresponding requirements to the tension member 16 to keep at least the sautäusserste layer of individual elements 10 at a distance.
  • the outer shell 20 may have on its outer side spirally extending grooves 40, which remove impurities such as dust, fat residues, etc. from the traction sheave. At least a portion of the grooves may be covered with a protruding, easily deformable band 42 which enhances the action of the grooves.
  • individual or a plurality of individual elements 10 can conduct electrical signals with anchoring end pieces arranged on both sides and with one Microprocessor, sensors and other peripheral devices connected.
  • FIGS. 14 and 15 show that this can also be done via optical conductors 44.
  • the central single element 10 of the previous figures is replaced by a steel or rigid polymer tube with three glass fibers.
  • five of the ten individual cores 10 are replaced by an optical conductor 44 each having a bundle core containing a glass fiber.
  • the light pulses are converted into electrical signals via an optocoupler.
  • At least one individual element 10 of a tensile material, in particular steel, is replaced by one or more substantially better electrical conductors 46, in particular of copper or aluminum or an alloy of these metals, in particular with an electrically insulating layer a thermoplastic.
  • electrical conductors 46 in particular of copper or aluminum or an alloy of these metals, in particular with an electrically insulating layer a thermoplastic.
  • optical or electrical conductors may be in any number at any location, e.g. 14 to 17 are used, but not usually in the outermost layer of individual elements 10. Further, individual elements 10, optical conductors 44 and electrical conductors 46 may be individually equipped with a coating. With or without coatings spacers in the form of fibers 28 and / or powders or granules 30 may be provided.

Abstract

L'invention concerne un élément de traction (16) flexible inversable, notamment pour ascenseurs, monte-charges, grues et véhicules. L'élément de traction (16) comprend au moins un câble (18) composé d'éléments individuels résistant à la traction, comme des fibres, des câbles et/ou des bandes. Au moins une partie des éléments individuels (10) du câble (18) est maintenue à distance par un revêtement (12) et/ou une charge sous forme de fibres (28) et/ou de poudre en vrac et respectivement des grenailles (30). Selon des variantes préférées, au moins un élément individuel (10) d'un câble (18) est remplacé par un fil (46) à bonne conductivité électrique ou par un conducteur optique (44).
