Definitions

  • the invention relates to a band-shaped biasing member according to the preamble of claim 1 and has for its object to produce a particularly simple biasing element.
  • EP 896 107 is a band-shaped biasing element has become known, which consists of a plurality of mutually parallel tendons, which are enclosed by a common, preferably plastic-existing, protective cover, wherein the tendons touching each other.
  • the protective cover is executed on the outside and inside, wherein the opposing gussets of two mutually contacting biasing elements are filled with corrosion protection grease.
  • the object of the invention is to create a band-shaped biasing element, which is even easier to manufacture. This object is achieved by the measure according to the characterizing part of claim 1.
  • tension members strands 1 are provided, which are juxtaposed man lying man and enclosed by a plastic protective cover 2.
  • the strands 1 are bare, i. not as each monolitzen surrounded by their own plastic sheath and wrapped in grease or a permanently plastic mass.
  • the gussets 4 in between are also filled with fat or the permanently plastic mass.
  • Fig. 1 follows the protective cover 2 of the shape of the strands 1 and therefore forms, as the figure can be seen, a waveform with hollows. 6
  • the wall thickness of the protective cover 2 is 1.3 to 1.8 mm, preferably 1.5 mm.
  • the fat layer enclosing the strands 1 may have a thickness of 0.3 to 0.6 mm, preferably 0.5 mm.
  • the protective cover 2 is usually extruded onto the band of the adjacent strands 1.
  • the protective cover 2 is pliers-like and can, as in Fig. 3 are shown, opened to insert the strands 1 in the wells 6, whereupon the protective cover 2 is closed and provided at the end with a weld 3.
  • the embodiments of the tendons according to the embodiments according to the Fig. 5 to 8 are mainly intended for special cases and have a wall thickness of the protective cover of preferably 1.5 to 5 mm, suitably 3 mm, which, inter alia, a higher corrosion protection than thinner protective sleeves after Fig. 1 can be achieved.
  • the band-shaped biasing member are the prefabricated halves 2 ', 2 "of the protective cover 2 on the outside in the region of each trough 6 with a flattening 7', 7" provided, between each two aufeinaderur flats 7 ', 7 "in each case a trough 8 is present
  • This embodiment is preferably intended for external applications.
  • the Fig. 7 discloses an embodiment of a band-shaped biasing element in which the outer surface of the protective cover 2 is flat.
  • the embodiment of the band-shaped biasing element according to Fig. 8 is similar to the biasing element after Fig. 7 with the difference that the inner waves omitted and the protective cover 2 inside has a flat surface 2a.
  • the protective cover 2 may also have a cassette shape, that is, both halves 2 ', 2 "may each be formed as an independent molded body, wherein the two cassette halves stacked and similar as in the embodiment of the protective cover 2 after Fig. 4 be welded at the ends.
  • the band-shaped biasing elements 2 such as Fig. 9 shows, stacked on top of each other, wherein the strands 1 and the tendons of the bands are aligned over each other. They can also be offset from each other.
  • band-shaped biasing elements In the embodiment of the band-shaped biasing elements according to Fig. 10 are the band-shaped biasing elements offset by half the diameter d / 2 of the tendons 1 to each other.
  • the to be welded, abutting ends 10, 11 of the protective cover 2 are, as Fig. 11 shows, dressed to protect them from penetrating grease or the permanent plastic mass.
