Definitions

  • the invention relates to a support for rail vehicles by means of air spring systems, which each consist of an air spring and an additional spring, preferably a rubber additional spring, are provided one or more times between the body and the drives and take over the transverse suspension and the rotation of the vehicle.
  • a support system for rail vehicles (WO 95/18743) is known, in which it is proposed to improve the lateral rigidity and the cardanic stress in tilting technology, an additional spherical spring at the upper end of the gas spring (air spring) to arrange.
  • This solution has the disadvantage that the spherical spring not only develops its effect in the intended direction, but undesirable effects or conditions also occur, for example, in the vertical direction of loading or when the drive rotates.
  • the additional spherical spring significantly reduces the buckling and torsional rigidity of the spring system, in particular if a layer spring is arranged under the gas spring.
  • Another disadvantage is that the effect of the spherical spring is present in the entire range of motion of the spring system, that is, the reduced transverse stiffness must be hardened towards the end of the transverse spring travel by additional components, so that sudden, unpleasant attacks are avoided.
  • the transverse spring constant of an air bellows is not a fixed variable, but is, for example, dependent on the transverse spring travel in addition to the internal bellows pressure and the speed of movement.
  • the transverse suspension in the frequently occurring small transverse deflections is significantly harder than in the rarer, large transverse suspension paths, which leads to a negative effect on vehicle running and driving comfort.
  • the invention specified in the patent is based on the problem of providing a support for rail vehicles by means of air spring systems which ensures a low transverse spring characteristic of the vehicle with small transverse spring paths and which does not have any adverse effects on the vertical suspension and the rotation of the drive.
  • the object is achieved in that a rolling device with a rolling direction oriented transversely to the vehicle is arranged between the air spring system and the running gear, the effective radius R of which is approximately the same as or greater than the height of the air spring system and its rolling area.
  • the roller device is formed by a roller plate arranged on the lower support surface of the air spring system or elements located thereon with a central, rounded roller blade and a flat counter bearing surface attached to the drive.
  • the roller cutter on both sides of tangent flat surfaces is limited, the opening angle ⁇ defines and limits the rolling area of the device. It is furthermore according to the invention that the roller device is secured against rotation, displacement and lifting by stops and strips.
  • the advantages of the solution according to the invention lie in particular in the fact that largely conventional and thus proven and inexpensive air spring systems in combination with the roller device enable a defined configuration of the transverse spring behavior.
  • the radius R of the rolling device and the rolling area By selecting the radius R of the rolling device and the rolling area, on the one hand the size of the transverse spring characteristic and on the other hand the area of influence can be easily adapted to the special requirements of each vehicle.
  • the solution is also so advantageous because the positive effect only occurs in the desired direction without affecting the vertical spring and horizontal unscrewing characteristics.
  • the low height of the device also ensures problem-free use, even with drives with limited space.
  • the car body 1 is supported on the drive 3 in an arrangement (not shown in detail, but generally customary) via air spring systems 2 arranged symmetrically to the center of the drive.
  • the air spring system 2 consists of the air spring 4, here provided as a half-bellows, and the rubber additional spring 5, here designed as a conical spring.
  • the half-bellows is necessary because, in addition to the transverse movement, the bellow must also absorb the turning movements when traveling through bends.
  • the cone spring was because of the comparative great vertical elasticity with existing buckling stiffness selected.
  • the roller device 6 is arranged below the air spring system 2, the roller cutter 7 of which is aligned in the longitudinal direction of the vehicle.
  • the roller device 6 consists of a roller plate 8 fastened to the rubber additional spring 5 and a flat counter bearing surface 9 located on the carriage 3.
  • the roller cutter 7, formed centrally on the roller plate 8, has a radius R which is approximately equal to or greater than the height of the air spring system 2, whereby also to generate a progression this radius can increase with increasing cross stop.
  • the special design is based on the elasticity of the transverse suspension of the car body 1 to be achieved.
  • flat surfaces 10 are arranged on the roller plate 8 at an opening angle ⁇ , which define and limit the rolling area of the support.
  • Fig. 1 shows the entire support for the case of a stationary rail vehicle on a straight track, that is, a load of the support with only vertical forces. All components take their symmetrical middle position.
  • roller device 6 In operational use, it must be ensured that the roller device 6 is retained in the intended arrangement, for which purpose the form-fitting design of the roller plate 8 in connection with corresponding ones according to FIG. 3 Stops 11 against twisting and moving was chosen. An additional bar 12 also ensures that the roller plate 8 is not lifted off.
