Definitions
- Rail track brake control In technical tailings systems, which are also referred to as train formation systems, processes in the form of cars or groups of cars are sorted into a different direction track using the gravity acting on the processes from a mountain track. Done in terms of efficiency and reliability in this case usually a broad Au ⁇ tomation operation oftownanläge.
- a suitable for this purpose automatic control system is in ⁇ play, from the company publication "automation system for train formation ⁇ Trackguard Cargo MSR32 - More efficiency and safety in the transport of goods", Order No .:
- the corresponding track brakes can be, in particular, mountain brakes, valley brakes, directional track brakes or roll-stop brakes.
- the track brakes in question are usually integrated via a corresponding rail brake control in the automated operation of the technical equipment.
- hill and valley brakes are controlled so that the inlet velocity of the processes in the next brake disc does not exceed a certain maximum and the necessary to place the distribution points distance between see the procedures is respected.
- Rail brakes in technical systems are often designed as a rail track brakes, in which a braking force is generated, that brake beams are pressed at high pressure on one or both sides of the flanks of the wheels oftownrol ⁇ ing rail vehicles in the form of processes. As a result, a friction effect is caused by the based on the vehicle movement, a braking force is generated.
- the present invention has for its object to provide a bar rail brake control, by which the quality and safety of the operation of technical systems is further improved.
- a rail vehicle braked in the rail track brake ie generally a freight car or wagon
- the corresponding limit from which it comes to a climbing of the rail vehicle can not be accurately determined or predicted in advance.
- effects on the respective wheel or the respective axis of the rail vehicle play a role in addition to speed and weight of the jewei ⁇ time rail vehicle.
- This can be, for example, environmental conditions, for example in the form of weather or moisture, or else parameters specific to the respective wheel, such as wheel bandages or wheel widths.
- the rail track brake controller of the present invention now addresses the above-mentioned problems by having first means for detecting a wheel-climbing of the rail vehicle braked in the rail track brake.
- the rail track brake control according to the invention has the advantage that it allows to detect a climbing of a wheel of a rail vehicle braked in the rail track brake and to respond to this with a reduction of the braking force of the rail track brake.
- By an appropriate adjustment of the braking force may thus result in impairments due to a shunting Aufkletterns of a rail vehicle in the beam track brake, given ⁇ connected to a subsequent derailment can be prevented if.
- the inventive beam track ⁇ brake control allows the application of an appropriate in the respective situation-or optimum braking force, wherein in particular avoided that consistently too low a braking force is applied to avoid possible Aufkletterns a wheel of the rail vehicle.
- the bar rail brake control comprises well as ⁇ the first means for detecting the Aufkletterns of Ra ⁇ of the braked in the bar rail brake the railway vehicle, ie in particular a corresponding sensor, as also the control device.
- the latter can be decentralized, such as in the vicinity of the respective retarder, or centrally ⁇ assigns his example and one or more control computing ⁇ ner.
- the first means and the control device each comprise both hardware and software components.
