Definitions

  • the invention relates to a flexible hose, in particular charge air hose, with at least three layers, one layer being designed as a reinforcing layer and two layers having an elastomeric material.
  • charge air hoses to transfer hot air from the engine to the air cooler has been known for a long time.
  • the charge air temperatures are approx. 200 ° C, with an overpressure of 2.5 bar.
  • Four-layer charge air hoses are known for these temperature ranges, comprising an inner layer made of FPM, an intermediate and outer layer made of silicone and a reinforcing layer, e.g. made from an aramid fiber.
  • the use of silicone is indispensable for use in the high temperature range, since the conventional rubber compounds are not stable at these temperatures and pressures.
  • hoses made from the above materials are relatively expensive to manufacture because the materials used, especially the FPM, as well as the silicone, are expensive. At the same time, the use of four shifts increases costs. Here, however, four layers are necessary to achieve a combination of all the desired properties, especially since sili . con must be protected from the aggressive fuel film. As a result, these hoses are used in particular in engines that also require higher temperature resistance.
  • hoses are also known which are primarily suitable for use in areas with low temperature.
  • hoses with a three-layer structure have proven their worth, comprising an interior inner layer made of AEM (ethylene-acrylate rubber), a reinforcing layer and an outer layer made of AEM.
  • AEM ethylene-acrylate rubber
  • these hoses are cheap to manufacture, they are only suitable for the so-called cold area.
  • the object of the present invention is therefore to provide a hose which is suitable for temperature ranges below 200 ° C. and is inexpensive to produce.
  • a flexible hose in particular charge air hose, with at least three layers, one layer being designed as a reinforcement layer and two layers having an elastomeric material, in that one of the three layers contains acrylate rubber (ACM) and that the reinforcement layer Contains aramid fibers.
  • ACM acrylate rubber
  • the hose according to the invention is characterized by good resistance to the ambient atmosphere and the materials used in a temperature range up to 200 ° C, at the same time offers sufficient strength and durability and is inexpensive to manufacture.
  • the ACM material used is characterized by particularly good aging and ozone resistance.
  • aramid fibers can be used as the reinforcement layer.
  • the aramid fibers used give the hose sufficient strength while at the same time maintaining flexibility of the hose.
  • aramid fibers have proven to be particularly suitable for absorbing pressure waves.
  • the reinforcement layer can contain Kevlar®. This material has proven to be particularly suitable in practice. Kevlar® is a Dupont product consisting of poly (p-phenylene terephthalamide), which is characterized by good temperature resistance, good tensile strength and a good modulus of elasticity with low density.
  • the reinforcement layer can contain Nomex®.
  • Good properties of the hose could also be obtained using Nomex®.
  • Nomex® is also manufactured by Dupont and consists of poly (m-phenylene isophthalamide). This material is characterized in particular by good thermal properties and flame-resistant properties.
  • the reinforcement layer can advantageously contain a combination of Kevlar® and Nomex®. This makes it possible to combine the advantages of both materials without the need for an additional layer.
  • the reinforcement layer can be formed as a middle layer. In this way, the reinforcement layer is protected from both sides against damage and against influences from the ambient atmosphere.
  • the reinforcement layer can advantageously be braided, wound or knitted. All of the methods mentioned have proven particularly suitable in practice. In this context, knitting is characterized in particular by the lower material consumption compared to the other two methods mentioned, which in turn is reflected in the total cost of the hose.
  • the inner layer and the outer layer can contain ACM.
  • ACM has proven itself in this context Material that is suitable for both the inside and outside view has been proven to meet the requirements of the respective layer well. By using one and the same material for both layers, the production is simplified at the same time, since different raw materials do not have to be stored and the coextrusion can also be simplified.
  • a further preferred embodiment can provide that the hose can be used from room temperature to a maximum of 200 ° C.
  • the flexible hose can advantageously be designed in the form of a corrugated tube. This makes it possible to increase the flexibility of the hose even further. At the same time, the hose can be used in a wide variety of applications.
  • Figure 1 is a three-dimensional view of a charge air hose.
  • the hose 1 shown in Figure 1 consists of three successively arranged layers. For the sake of clarity, the individual layers are shown alone in the initial area, ie one area of each layer is exposed.
  • the hose 1 comprises an inner layer 2, a reinforcing layer 3, and an outer layer 4.
  • the inner layer 2 consists of ACM and is provided with a reinforcing layer made of Kevlar® lying directly on it.
  • the reinforcement layer can completely encase the inner layer 2, for example if it is woven, but can also be designed as an open braid so that the outer layer 3 applied to the reinforcement layer has direct contact with the inner layer through the open braid.
  • Such an open braid e.g. B. knitted fabric, can therefore for better adhesion between see the individual layers contribute.
  • the outer layer also consists of ACM.
