  • One-piece chain webs which consist for example of steel, but are too heavy for normal operation.
  • multi-part chain webs are used, in which a strip, for example a so-called wear rail in the form of a toothed strip, which is usually made of steel, in a carrier of a lighter material, in particular a light metal, such as aluminum, or plastic, inserted into the receiving area of the carrier.
  • Such strips are usually inserted into the receiving area of the carrier by mechanical fasteners, such as e.g. by rivets, screws or bolts connected to each other to keep the strip from falling out or a lateral displacement.
  • a disadvantage of such chain webs is that the chain webs frequently break due to the weakening of the material in the region of the mechanical connecting elements.
  • the object of the invention is therefore the development of a chain web with reduced fracture properties.
  • the strip is at least partially glued and / or welded into the receiving area.
  • the strip should be connected to the carrier in such a way that no mechanical connecting elements such as screws or bolts are required, which usually weaken the chain webs and thus make them susceptible to breakage.

  • an at least partially frictional introduction of the strip in the receiving area of the carrier is low.
  • a frictional introduction can be done for example by compressing the carrier with a form-fitting introduced bar or by inserting a bar in the receiving area of the carrier without play. In particular, in the area where the drive wheel of the tracked vehicle engages in the bar, this can be beneficial.

  • a preferred embodiment provides for the use of an anaerobic adhesive based on urethane and Methalcrylat.
  • Anaeobhärtende adhesives are so far favorable and therefore preferred according to the invention, since they can be introduced into joints and harden well without the supply of oxygen. Therefore, it is convenient to introduce an anaerobic adhesive in the receiving area of the carrier and then insert the bar. Hardening is complete even in the absence of oxygen.
  • such adhesives have particularly favorable adhesive properties, since they have ideal adhesive properties even in a very broad temperature range. In fact, such adhesives are often used to bond metal to metal. But according to the invention, other adhesives are conceivable. In particular, if they have similarly good thermal properties and similarly good adhesive properties of metal on metal.
  • the invention also relates to a method for producing a chain web for a track of caterpillars, especially snow groomers or trailers, with a carrier having a receiving area for an inserted bar, in particular chain webs of the aforementioned type, wherein the bar and the carrier made of different materials, especially metals or Alloys, exist.
