Definitions

  • the invention relates to a coupling head for a track-guided vehicle, in particular rail vehicle, in detail with the features of the preamble of claim 1.
  • the invention further relates to an automatic clutch with such a coupling head and a method for detecting a coupling state of such an automatic clutch.
  • Such a latch transmission with a display is for example from the document DE 1 808 167 A previously known.
  • the required visual inspection is especially in train assemblies from a variety of to be coupled to individual car units disadvantageous because time-consuming. Automated uncoupling and engagement processes are made more difficult.
  • the display options are also limited in terms of recognizability. As a rule, only the functional states “coupled” or “uncoupled” are indicated by the sticking out and not sticking out of the housing of the coupling. Intermediate positions are not recognizable or can only be realized with additional constructive effort.
  • the invention is therefore an object of the invention to provide a coupling head and a coupling in which a detection of the coupling state is easy and with high security quickly and without errors feasible.
  • the solution according to the invention should be characterized by a low design and control engineering effort.
  • a coupling consists of two coupling halves which can be brought into operative connection with one another, the individual coupling half having a coupling head which carries or forms a coupling profile.
  • the coupling profile is preferably of the Willison type. This includes two different sized and offset in the horizontal plane to Clutch longitudinal axis arranged claws, which form a in the vertical direction from the top to the bottom of the coupling head in the installed position extending clutch pocket for receiving the coupling profile of the counter-coupling head.
  • a dome state describes the characterized by the position of the individual components of the coupling head operating states in the interaction of two coupling heads - a coupling head and a counter-coupling head.
  • Each coupling state is defined by a defined functional position of the respective individual components - bar or bar holder.
  • one or more dome states also overlap, that is, one or more dome states may be characterized by the same positions of a component.
  • the coupling state "ready to be coupled” is characterized by the alignment and sliding of the individual, to be coupled coupling heads.
  • the coupled state "coupled” is characterized by the interlocking of the coupling profiles and mechanical connection via a locking gear.
  • the coupling state "uncoupled” is characterized by the interlocking of the coupling profiles and mechanical separation by unlocking the locking gear.
  • Porition is understood to mean a specifically defined spatial position of a single component of the locking mechanism in the clutch pocket and / or in relation to the counter-coupling head. These can be end positions or intermediate positions that can be captured at least for a limited time.
  • Detection of a variable describing a state or process involves the detection, detection, detection and optionally transformation, storage and / or transmission of the information. There are no restrictions regarding the type of the selected transmission path.
  • At least one position of the bolt holder or locking element at least indirectly descriptive size is understood a quantitative or qualitative measure that either directly characterizes a defined position of a component or indirectly describes this, for example, via a functional dependence or can be derived in any other way from this ,
  • Locking and unlocking devices can be designed in various ways. These can be formed for example by an effective between locking element and latch holder pawl and a locking shaft with cams are formed for unlocking, which is effective on the pawl and thus releases the locking element in terms of its mobility.
  • the advantage of the invention is thus in the automated detection of the dome state, for example, from the cab of a locomotive or RangierInstitutes.
  • a remote-controlled uncoupling process by a decoupling cylinder new perspectives for the automated coupling process in the field of freight wagons and locomotives in shunting and train formation arise.
  • the invention thus relates to a coupling head of an automatic central buffer coupling of the type Willison-SA-3, in particular the automatic monitoring of the coupling closure position with automatic detection of the counter-coupling and detection of the coupled and uncoupled state by querying the position of the closure components bolt and bolt holder by appropriately arranged sensors or switch.
  • the detection of the coupled state is independent of the type, provided that the coupling profile of the counter-coupling is designed according to the requirements de UIC 523 or GOST 21447-75.
  • Central buffer couplings with type Willison coupling heads are used for mechanically connecting two adjacent car bodies, for example a rail vehicle, and are distinguished by their robust construction, so that such coupling heads are frequently used in freight wagon clutches and locomotives.
  • the structure and operation of a coupling head type Willison are, for example, in the document DE 1 455 242 A described.
  • the number of positions of the individual components of the locking gear and / or the type of size to be detected depends on the design of the respective detection device.
  • the first device for detecting at least one, at least one position of the latch holder at least indirectly descriptive size is arranged and designed to be suitable to detect only a first or second position of the latch holder.
  • simple binary sensors can be used, which only generate a signal in one of the coupling states. False indications of non-functioning of the respective facilities can not be excluded.
  • both positions are detected so that dome states can be reliably detected and assigned.
  • the statements made in advance also apply to the second device for detecting at least one variable, at least one position of the locking element, which at least indirectly describes its size and its first and second positions.
  • the former possibility offers the advantage of retrofitting and free placement within the coupling head.
  • the second and third possibility requires corresponding reference surfaces or points on the coupling head.
  • non-contact sensors are used for reasons of wear.
  • the size describing the respective position for example, a distance between a reference plane and a component, a position, a pressure, a change of an electric or magnetic field.

  • electromechanical sensors are used. These are preferably designed as tactile sensors and may be in the form of switches. These switches are positioned relative to the latch and the latch holder so that, when both signals are present, an evaluation and a reliable result with respect to the coupling state is possible.
  • FIG. 4 illustrates by way of example the detection of the individual signals via the individual devices 17 and 18, which are connected to a corresponding one Evaluation device 19 are coupled, which may be part of a control device and in response to the present signals is a manipulated variable Y for displaying the coupling state.
  • the evaluation device 19 is connected to the means for detecting 17 and 18 signal transmitting.
  • the coupling can be realized wirelessly or via connecting lines.
  • the evaluation device is connected to an adjusting device 21 of a display device for the dome state. In the simplest case, this is a visual display device.
  • each of the devices can be coupled separately with the evaluation device.
  • binary sensors When binary sensors are used, they can be arranged and operated such that they either generate a signal for the detection of a specific position or do not generate a signal. If the first device is positioned relative to the latch holder in such a way that it emits a signal "coupled” only in the coupling position, the arrangement range is such that no signal is produced in the functional position "ready to be coupled", but a signal is generated in the coupling position. In this case, a signal is always generated in the presence of a counter-coupling. The second device is arranged and positioned in this case so that only in the coupling position "coupled” a signal and in the dome-ready position, a signal are generated, while in the coupling position "uncoupled” no signal is generated.
