Definitions

  • the invention relates to a method for condition-based maintenance of a clutch arrangement for track-guided vehicles, in particular rail vehicles, and also to a monitoring system.
  • guided vehicle includes, but is not limited to, trains, wagons and railcars that run or are guided on one or more rails. These are in particular fuel-powered or electric trains or trams.
  • the term “coupling arrangement” is primarily to be understood as meaning at least that part of a coupling system of track-guided vehicles which enables the mechanical connection between the two vehicles.
  • the coupling arrangement makes it possible to absorb and pass on both impact and tensile forces. These are mounted or designed on the rail vehicles in such a way that they can be displaced and pivoted in a curve or incline in order to maintain their alignment and thus the mechanical coupling in a stable manner.
  • the coupling arrangement includes in particular a coupling head with coupling elements for coupling to a coupling head of a counter-coupling, furthermore, depending on the design, a coupling rod, a linkage or bearing and optionally energy-absorbing elements.
  • the term coupling arrangement includes here in particular all elements from the interface to the car body to the interface for coupling to the counter-coupling.
  • the coupling arrangements and their individual components are usually designed for a specific application in order to be mechanically stable and reliably coupled to one another in the most varied of situations; regardless of rail vehicle type and/or straight or curved track sections on horizontal plane or with incline. Further, the interpretation is made to predefined To be able to transmit tensile forces over a predefined operating period and to compensate for impact forces of a predefined size. For this purpose, it is provided in such clutch arrangements that a damping device absorbs tensile and impact forces up to a defined magnitude and transmits forces in excess of this to the vehicle underframe.
  • the damping device is not able to fundamentally prevent tensile and impact forces from being introduced into the components of the clutch arrangement. As a result, the components of the clutch assembly are exposed to more or less permanent wear during operation.
  • the clutch arrangements are also exposed to a wide range of other conditions which can have a not inconsiderable influence on the theoretically intended service life of the individual components of the clutch arrangement.
  • the wear of the clutch arrangement during the coupling process can increase if the self-centering of the clutch arrangements to be coupled to one another is made more difficult if the clutches are farther apart or offset from one another.
  • intervals are predefined in such a way that a failure of individual components due to wear is avoided under normal conditions with certainty before the maintenance time is reached.
  • a predefined period of time is usually specified or the maintenance request is made defined over a distance covered by the rail vehicle that describes the operating time.
  • the information on the operating mode and condition of the clutch arrangement obtained from the clutch arrangements associated monitoring systems can be used to support inspection and maintenance.
  • a monitoring system is described in DE 102013 206977 A1, for example.
  • US 2018/0162423 A1 provides a monitoring system that detects the structural changes directly on the coupling itself, in particular on the coupling rod.
  • DE 10 2019 106 961 A1 describes the arrangement of
  • condition monitoring system for train couplings which detects both external and internal structural damage, including damage to the part hidden under the car body, even when the train is in operation.
  • the condition monitoring system includes one or more sensors mounted on or integrated into the coupler assembly, a data acquisition unit for receiving signals or data from the sensors, and a processing unit for determining the structural condition of the train coupler based on the received signal or data. Controls over the system can be continuously real-time or carried out periodically during the operation of a train. It can also be done offline while a train is not running.
  • Detection devices require additional modifications to the individual components, in particular the clutch arrangement, and ensuring the functional reliability of the detection devices and monitoring systems is complex and costly.
  • DE 102015205978 A1 describes a system for documenting the state of a motor vehicle by means of image and data acquisition with time assignment by setting a time stamp.
  • the invention is therefore based on the object of specifying a method for servicing clutch arrangements which, with the least possible additional design effort on the clutch arrangement itself, enables relatively reliable statements to be made regarding required servicing/maintenance, with unnecessary downtimes being to be avoided. It must be ensured that the individual components of the clutch arrangement - even after a long period of operation - function properly and are integrated accordingly into the overall clutch concept of the vehicle, without the individual components of the clutch arrangement being individually and regularly connected to a classic
  • the method according to the invention for condition-based maintenance of a coupling arrangement of a rail-guided vehicle, the coupling arrangement having at least one coupling head for coupling to a coupling head of the opposite type of a counter-coupling and optionally at least one line coupling for coupling to a line coupling of a counter-coupling for transmitting electrical charge and/or data and/or liquid or gaseous media comprises the following method steps: a) providing clutch arrangement data in the form of operating data and optionally status data of the clutch arrangement; b) providing environmental data to describe information about the environmental conditions to which the clutch arrangement is exposed; c) Transmitting the provided data to a data processing system and determining a target specification for a maintenance request for the clutch arrangement as a function of the provided clutch arrangement data and environment data; d) recording of images of the clutch arrangement for optical reproduction of the actual state and transmission to the data processing system; e) Evaluation of the optical actual state of the clutch arrangement from the images, taking into account the target specification for the maintenance request formed from the operating and state data
  • “Clutch arrangement data” within the meaning of the invention is understood to mean, in particular, data which is suitable, at least indirectly, for describing the mode of operation of the clutch arrangement and its individual components and/or the environmental conditions. These include operating data, environmental data and optionally but not necessarily status data.

  • variant a) also includes downtimes, in which the clutch arrangement can also be exposed to extreme weather conditions
  • variant b) includes the actual operating period in which the clutch arrangement is exposed to the loads.
  • Variant c) in particular allows the next required maintenance to be determined very precisely in advance and makes it possible to plan it well, in particular with regard to the area of use of the rail vehicle carrying the coupling arrangement.
  • the provided clutch arrangement data, the environmental data and the data containing the images are provided with a time stamp and stored together with this.
  • the changes in the data over time become transparent and the change behavior of these over a defined period of time can also be taken into account and conclusions can be drawn from these for the remaining service life.
