Definitions

  • the invention relates to a support for rail vehicles, by means of an air spring system, each consisting of an air spring as well an additional spring, preferably a rubber additional spring, one or more times between the body and the Drives are provided and the cross suspension and the rotation of the vehicle.
  • Air suspension systems are mainly used for vertical vehicle suspension, but are predominantly for economic reasons at the same time for the transverse suspension of the vehicle and the turning movement of the drive used.
  • the air spring system in the generally as a series and / or parallel connection of Air and rubber additional spring built.
  • the additional dome spring reduces the Buckling and torsional rigidity of the spring system in particular then very significantly, if according to claim 2 under the gas spring a layer spring is arranged.
  • Another disadvantage is in that the effect of the spherical spring in the entire range of motion of the spring system is present, that is, the reduced Lateral stiffness must pass towards the end of the transverse spring travel additional components are hardened again so that sudden, unpleasant attacks can be avoided.
  • transverse spring constant an air bag is not a fixed size, but for example in addition to the inner bellows pressure and the speed of movement also depends on the transverse spring travel.
  • transverse suspension for the frequently occurring small transverse deflections significantly harder than with the rarer large cross spring travel, which has a negative effect on vehicle running and Driving comfort leads.
  • the invention specified in the patent claim is the problem is based on supporting rail vehicles using air suspension systems to create which has a low transverse spring characteristic of the vehicle with small transverse spring travel and which have no adverse effects on vertical suspension and causing the drive to spin.
  • the object is achieved by between the air spring system and the running gear with a roller device is arranged transversely to the vehicle oriented rolling direction, the effective radius R approximately equal to or greater than the height of the air suspension system and its roll range are limited is.
  • the rolling device by one on the lower support surface of the air spring system or elements arranged thereon with a roller plate central, rounded roller cutter and one attached to the drive flat counter bearing surface is formed.
  • the rotary cutter on both sides of tangent flat surfaces is limited, their opening angle ⁇ defines and limits the roll area of the facility.
  • the rolling device through Stops and strips against twisting, moving and lifting is secured.
  • the advantages of the solution according to the invention are in particular in the fact that it is largely conventional and therefore proven and cost-effective Air spring systems in combination with the roller device enable a defined design of the transverse spring behavior.
  • the radius R of the roller device and the Roll range can on the one hand the size of the transverse spring characteristic and on the other hand the area of influencing the special The requirements of each vehicle can be easily adapted.
  • the solution is also advantageous because it is exclusive in the desired direction the positive effect occurs without the vertical spring and horizontal unscrewing characteristics to influence. The low height of the facility ensures also the problem-free use even with drives with limited space.
  • the car body 1 is supported in a not shown, but generally common arrangement about symmetrical to the center of the drive arranged air spring systems 2 on the drive 3. It can be two or more air spring systems 2 per drive 3 trade.
  • 1 that is Air spring system 2 from the air spring 4, here provided as a 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 also the turning movements during bends are taken up by the bellows Need to become.
  • the cone spring was because of the comparative great vertical elasticity with existing buckling stiffness selected.
  • Below the air spring system 2 is the Rolling device 6 arranged, the roller cutter 7 in the vehicle longitudinal direction is aligned.
  • Roll device 6 from a attached to the rubber auxiliary spring 5 Roller plate 8 and a level on the drive 3 Counter bearing surface 9.
  • the roller cutter 7, centered on the roller plate 8 formed, has a radius R, which is approximately the same or greater the height of the air spring system 2, whereby also for Generation of a progression of this radius with increasing cross stop can get bigger.
  • the special design judges the elasticity of the transverse suspension of the Carriage body 1.
  • Both sides of the roller cutter 7 are on the Roll plate 8 flat surfaces 10 arranged at an opening angle a, that define and limit the roll area of the support.
  • Fig. 1 shows the entire support for the case of a stationary rail vehicle in a straight track, that is, a load on the support with only vertical Powers. All components take their symmetrical middle position on.
