Definitions

  • the present invention relates to an air spring having reinforcement material in which twisted monofilament cords are present.
  • the suspension system placed between the vehicle body and the tires is designed to damp the vibrations originated from the structure of the road.
  • the suspension system is a system required in terms of driving comfort and safety.
  • Air springs are one of the most important parts of this system. It is expected to protect the structure of the air springs against the vibrations it take and thus to have high dynamic performance.
  • the air springs are reinforced with polymeric textile material in order to provide the said desired properties.
  • the reinforcement materials that used are manufactured by twisting and weaving the fibers comprised of multifilaments and they are subjected to chemical process. The friction between the filaments in the said reinforcement materials, comprising multifilaments, affects the dynamic properties negatively.
  • air springs the dynamic properties of which are improved are provided which are reinforced with textile reinforcement material formed by twisting monofilament structures with each other.
  • Japanese Patent document no JP2006035750 an application known in the state of the art, discloses a manufacturing method for bellows rubber hose.
  • the bellows which is manufactured has laminated structure and it is comprised of rubber inner pipe, the reinforcing layer on the outer peripheral side thereof and an outer surface rubber layer.
  • the inner pipe is manufactured from vulcanized rubber material and the outer layer is manufactured from unvulcanized rubber material.
  • the objective of the present invention is to provide an air spring comprising reinforcement material which has low diameter monofilament cords.
  • a further objective of the present invention is to provide an air spring having reinforcement material wherein monofilament structures are used by being twisted.

  • twisted monofilament cord is used in at least one layer of the reinforcement zone (3), and by means of this use air spring with increased dynamic performance and explosion pressure is developed.
  • At least one of the layers in the reinforcement zone (3) is reinforced with twisted monofilaments comprising polymeric material with 3 to 12 plies and a thickness of at least 475 dtex.
  • the reinforcement zone (3) is comprised of two layers and both layers are reinforced with twisted monofilament cords ( Figure 1).
