Definitions

  • the present invention relates to a method for controlling an application device for friction value modifiers for a rail vehicle and a control device for an application device for friction value modifiers for a rail vehicle.
  • the effect of a brake or a drive device depends crucially on the frictional connection between the wheels and the rails, because a driving force or braking force is transmitted to the rails via the wheels.
  • a parameter known as the adhesion coefficient or adhesion coefficient determines the amount of braking force or driving force that can be transferred to the rail. If more force is applied to a wheel to brake or accelerate the rail vehicle than can be absorbed according to a prevailing traction across the wheel-rail contact, this can lead to slipping, skidding or locking of the wheel, which is an undesirable condition.
  • the adhesion between a wheel and a rail is highly dependent on the friction conditions between the wheel and the rail.
  • rail vehicles can be equipped with particle scattering systems, via which, for example, sand can be spread onto a rail as grit. The sand can improve the adhesion between wheel and rail, and thus the frictional connection.
  • stationary and vehicle-based systems for applying the friction value modifier.
  • friction pastes that are applied to the rail are usually used.
  • Vehicle-bound systems are usually scattering systems that scatter a granular medium (e.g. sand made of quartz or feldspar) onto the rail or directly into the wheel-rail gap.
  • the spreading system is activated either manually by the driver or automatically by the braking and traction system when anti-skid or anti-skid protection is activated.
  • the one to promote at activation Mass flow (delivery quantity over time) of the grit is defined in advance based on road tests or on the basis of standards and regulations.
  • the mass flow is constantly set in one stage (only one mass flow is set), speed-dependent in several stages (different mass flows are set in different speed ranges) or speed-dependent continuously (the relationship between vehicle speed and mass flow is represented by a continuous function).
  • a path-dependent flow rate can also be defined.
  • the DE 10 2011 113 085 A1 discloses a particle scattering system for a rail vehicle.
  • the static friction between wheel and rail must be improved. Poor static friction is caused on the one hand by the material condition of the wheels and rails, such as (rolling contact) material fatigue, rust, and on the other hand by environmental influences, such as natural environmental influences (snow, ice, moisture, rain, dust, leaves, etc.) and environmental pollution (Oil, grease, fine dust, etc.) and their combinations that are deposited on wheels and rails.
  • Different coefficient of friction modifiers offer different advantages in different situations. If an application device for coefficient of friction modifiers for a rail vehicle has at least two reservoirs for coefficient of friction modifiers, the optimum coefficient of friction modifier or a mixture of different coefficients of friction modifiers can be selected in different situations. The advantages of fluid friction value modifiers can also be used here.
