Definitions

  • the solution known from the prior art has various disadvantages. On the one hand, it is necessary to open the chain box to replace the chain rail. On the other hand, the correct chain slack can be ensured only by the targeted shoring of the chain slack optimal balancing chain rail. It is not excluded that by using a wrong chain rail is too low or too strong compensation. Furthermore, it is accepted in the prior art that is driven over a predefined operating range with a not optimally tensioned chain, which can lead to increased wear of the chain and thermal expansion, which can lead to the crack of the chain. Furthermore, it is problematic that in versions according to the prior art, in some cases only a single tensioning rail was used, which was installed either in Lostrum or Switzerlandtrum the chain to achieve the right voltage.
  • the chain “tensioning tensioning position” is understood to mean any position or extension of the chain tensioned in relation to a freely suspended state, the elastic element permanently exerting a tensioning force on the rails, which is transmitted directly from the rails to the chain In operation, the chain thus constantly slides along the rails and is biased by them, the material of the rails being selected such that there is no wear due to chain-to-rail friction, and preference is given to using two oppositely parallel rails ,
  • the chain facing side guide means are provided in a particular embodiment of the rails, which favors a guided sliding along the chain on the rails. Furthermore, it is favorable that the rails are formed curved, so that the edge regions of the respective rail are spaced to a plane of the chain.
  • Fig. 1 shows a perspective view of a tensioning device according to the invention a drive chain.
  • the invention is not limited in its execution to the above-mentioned preferred embodiments. Rather, a number of variants is conceivable, which of the solution shown at Generally speaking, it makes use of different types. For example, one rail may have a different curvature than the others.

Abstract

L'invention concerne un dispositif de tension d'une chaîne (2), destinée à une motocyclette ou une bicyclette, qui comporte des glissières (3) s'étendant le long de la chaîne (2) et disposées de façon au moins partiellement mobile, ledit dispositif comportant au moins un élément élastique relié aux glissières (3) avec précontrainte. La précontrainte de l'élément élastique agissant sur les glissières (3) déplace en permanence les glissières dans une position de tension de la chaîne (2) et exerce une force de tension sur les glissières (3).
