Definitions

  • the present invention relates to a tensioning or guide rail for an endless drive element, in particular a timing chain for an internal combustion engine, with a guide section which can be pressed onto the endless drive element and has a sliding guide surface and a support section supporting the guide section.
  • Tension rails such as those in large numbers e.g. used in timing chain drives for internal combustion engines must meet relatively high requirements.
  • the guide section is made of a different material than the support section.
  • an aluminum die-cast profile is used as the supporting section, on which a sliding lining body is attached, which has the desired sliding and guiding properties for pressing against an endless drive element.
  • this can also be designed to be replaceable.
  • the support section consists of a thermoplastic provided with fillers. The fillers are often glass fibers that serve as reinforcement.
  • thermoset material is or are made at least in regions from at least one thermoset material.
  • thermoset material Such a pairing of materials has not been used in the prior art. At first glance, the reasons for this are not obvious. However, thermosets were obviously not believed to have the desired properties, which is why metals or thermoplastics Have come into play. The priority of thermoplastics is very easy to explain, since injection molding technology has become well established and is very suitable for mass use. In addition to the cost-effective manufacture and provision of the desired properties and resistance to temperature and lubricant influences, the light weight of the thermoset material or the thermoset materials plays a major role.
  • the guide section and / or support section of the tensioning or guide rail can advantageously consist entirely of at least one thermoset material. This means, for example, that all fastening elements etc. of these components or the entire rail are or are made of the thermoset material or the thermoset materials.
  • the surfaces of the guide section and of the support section can be designed without post-processing by a thermoset molding process. This ensures that none of the surfaces of the guide section and the support section require machining processes for the final production. Rather, the thermoset molding process can produce very good surfaces up to very good flatness and surface quality.
  • thermoset molding process it is advantageous here, according to one variant, if all surfaces are designed without post-processing by means of a thermoset molding process. Accordingly, the entire tensioning or guide rail is produced by one or more thermoset molding processes.
  • the guide section can advantageously consist of a thermoset material with a lower coefficient of friction than the coefficient of friction of the thermoset material from which the support section consists. While the guide section must have the most favorable sliding friction conditions with low wear, the support section requires high strength. This can be taken into account by suitable selection of the appropriate thermoset materials.
  • thermoset material can preferably be a plastic based on phenolic resin with at least one filler.
  • Thermosetting materials based on phenolic resin are very well suited for the main application in the timing chain drive of an internal combustion engine and withstand the loads specified there with regard to the effects of lubricants and heat.
  • At least one thermoset material can have high heat resistance up to at least 140 ° C, preferably 160 ° C.
  • the thermoset including any fillers it contains, maintains its high mechanical properties (e.g. compressive strength, flexural strength) even at higher temperatures (e.g. at 140 ° C).
  • These mechanical properties can be of the order of magnitude of aluminum materials. Thermoplastics begin to flow at such temperatures, so that appropriate countermeasures have to be taken. These do not apply when using thermoset materials.
  • the thermoset materials proposed here can be subjected to high mechanical loads, far above the load values that are possible with thermoplastic materials.
  • the at least one filler is selected from the following group:
  • Glass fibers, glass balls, minerals, graphite, PTFE (Teflon) and MoS 2 Glass fibers, glass balls, minerals, graphite, PTFE (Teflon) and MoS 2 .
  • thermoset material can be selected so that there is a reduction in friction or greater strength. This can only be done in certain areas on the tensioning rail by deliberately influencing the material at the respective point.
  • thermoset material can be selected from the following group:
  • thermoset materials from the manufacturer mentioned are very well suited for use as tensioning or guide rails for a timing chain drive of an internal combustion engine. They are particularly resistant to heat and lubricants.
  • the figure shows a guide rail 1, which comprises a support body or support section 2 in a framework structure and a sliding surface or guide section 3.
  • the support body 2 has a lower rail 4 and an upper rail 5 carrying the sliding coating, which are connected to one another via cross struts 6 to produce the truss structure.
  • the sliding surface 3 is provided with an upper rail 5 e.g. connected by gluing and suitable connecting elements or locking options could also be provided. However, there is also the option of making a chemical-mechanical connection of the same or different materials / material types (e.g. a thermoset carrier that is chemically-mechanically connected to a thermoplastic covering).
  • a chemical-mechanical connection of the same or different materials / material types (e.g. a thermoset carrier that is chemically-mechanically connected to a thermoplastic covering).
  • the sliding coating 3 can be profiled on a sliding guide surface 7 in accordance with the accommodation of the endless drive element. For example, there could be side guide ridges, while the middle sliding area is lower.
  • the support body 2 and the sliding lining body 3 are each made of a different thermoset material. In another variant, these could also be made from a uniform thermoset material.
  • an X 689 is used as the thermoset material for the support body 2 and an X 620 for the sliding lining body 3.
  • These thermosets are available from Vyncolit (Ghent, Belgium) under the product name mentioned. In addition to the thermoset materials matched to the required properties, this guide rail 1 also has the advantage of low weight.
