    Wheel flange lubrication
    Technical field
    The invention relates to a wheel flange lubrication for a wheel flange of a rail vehicle wheel.
    State of the art
    In order to reduce wear on wheel flanges and rails, wheel flange lubrication is often used. It is equally important to prevent noise when the wheel-rail contact is dry, since the friction at this point can cause the wheel disc to vibrate in an audible frequency range. Typically, a lubricant is applied to the wheel flange on the foremost wheel set of a rail vehicle. It is essential not to apply this lubricant in such large quantities that it can reach the tread of the wheel and thereby reduce the friction between the wheel and the rail, since this would massively impair the braking effect. Various methods for applying the lubricant are known, for example a so-called lubricating pin made of dry lubricant can be pressed onto the wheel flange by means of spring force. This ensures a permanent lubricating effect, which, however, e.g. is unnecessary for long straight sections. This lubricating pin is naturally subject to wear and tear and should be checked regularly and replaced if necessary. Another, more complex type of wheel flange lubrication is the application of viscous
    2/15
    201626000
    Lubricant by means of compressed air. In this case, lubricant kept ready in a tank is sprayed on by compressed air, assisted by a nozzle in the immediate vicinity of the wheel flange. The lubricant is dosed by clocking the spraying process as a function of time or distance traveled. Compressed air systems of this type are very complex to manufacture and maintain; moreover, it is not guaranteed with these lubrications that lubrication takes place at a suitable time. For example, lubrication after a narrow curve is unnecessary. A further possibility of applying lubricant is provided by stationary lubrication devices which lubricate the flanges of the wheel sets passing by. Such devices are used, for example, in trams in front of sections of track with very small track radii. All wheel flange lubrications known from the prior art have defects, either lubrication is not adequately guaranteed at a certain point in time or unnecessary permanent lubrication takes place.
    Presentation of the invention
    The invention is therefore based on the object of specifying wheel flange lubrication which uses the specified lubricant supply economically, requires little maintenance and can be set up very inexpensively.
    The object is achieved by wheel flange lubrication according to claim 1. Advantageous refinements are the subject of subordinate claims.

    According to the basic idea of the invention, a wheel flange lubrication for a wheel flange of a rail vehicle wheel is constructed, which comprises a lubricating pin, the lubricating pin being mounted for longitudinal displacement and being able to be extended and retracted by means of a power-operated pressing device.
    This provides the advantage of being able to carry out the lubrication by means of the lubricating pin on certain occasions, in particular the permanent lubrication which otherwise occurs in the case of flange lubrication by means of a lubricating pin is eliminated. In this way, the lubricant is not
    Permanent lubrication wasted but only used when it is necessary. Compared to wheel flange lubrication systems which spray lubricants, the wheel flange lubrication system according to the invention is constructed much more simply and cost-effectively, since all lines (compressed air, lubricant) can be omitted.
    According to the invention, the lubricating pin is mounted to be longitudinally displaceable and can be extended and retracted by means of a power-operated pressing device. This can be done for example by means of an electromagnet or an electric motor. Actuation using compressed air is also possible, but this requires corresponding piping in the chassis and thus gives up an advantage inherent in the subject invention.
    The power-operated pressing device is preferably to be arranged in the undercarriage or bogie of the rail vehicle in such a way that only the relative movement when the lubricating pin is extended with respect to the surface of the lubricating pin
    4/15
    201626000
    Rades occurs. Further relative movements, for example due to the deflection of the vehicle, are to be avoided. In this way, mechanical stress on the lubricating pin, in particular transverse to its longitudinal axis, is avoided. For this purpose, the force-actuated pressing device can be arranged at a position of the undercarriage which has no relative movement to the surface of the wheel to be lubricated during operation. Such positions can be found, for example, on components within the so-called unsprung mass.
    The movement of the lubricating pin is controlled by means of a control device which controls the power-operated pressing device as a function of certain control signals supplied to the control device via a data interface. This control device comprises the corresponding electronic circuits for controlling the electric motor or electromagnets and circuits for signal processing.
    A control device is typically provided for both pressing devices of a lubricated axle.
    The lubrication processes are preferably triggered depending on the position of the vehicle on the track, so that it is ensured that lubrication to the required extent takes place in good time before relevant sections of the track (e.g. narrow bends). For this purpose, a control signal supplied to the control device can include information about the current position of the rail vehicle on the route, so that the control device triggers the lubrication process. For this purpose, a data record representing the route is stored in the control device, in which the points at which lubrication is to be carried out are also stored.

    A further embodiment of the invention provides for the route data usually stored in a vehicle control system to be expanded by the necessary lubrication points and to supply the control device of the wheel flange lubrication with a control signal which effects a lubrication process. In this way, the control device can be made simpler since it does not have to store route data.
    The duration of a lubrication process is to be determined depending on the properties of the lubricating pin used, for which purpose the optimal duration, in which a sufficient amount of lubricant is applied to the flange, may need to be determined experimentally.
    A preferred embodiment of the invention provides for the force-actuated pressing device to be designed such that a wear indicator signal is emitted to the control device when the lubricating pin extends a certain distance. As a result, the control device can emit a signal to a vehicle control which indicates to the driver or maintenance personnel that the lubricant pin has worn out at an advanced level. In this way, the advantage can be achieved of being able to carry out simplified maintenance, since a lubricating pin does not need to be checked during its service life and is therefore only replaced when the need arises.
    In a further development of the invention, it is advisable to equip the power-operated pressing device with a device for limiting the maximum extension force acting on the lubricating pin. This ensures that the lubricating pin is not exposed to wear due to excessive pressure.

    Brief description of the drawings
    The following are examples:
    Fig.l wheel flange lubrication.
    Implementation of the invention
    Fig.l shows an example and schematically a wheel flange lubrication. A wheel flange lubrication for a rail vehicle wheel 1 is shown, the view being oriented normal to the axis of rotation of the rail vehicle wheel 1. A power-operated pressing device 3 comprises a linear displacement device for a lubricating pin 2. The lubricating pin 2 is in contact with the wheel flange of the rail vehicle wheel 1 at one end, FIG. 1 represents the position of the lubricating pin 2 during a lubricating process. Furthermore, the power-operated pressing device 3 comprises a power drive for the movement of the lubricating pin 2 in the retracting and extending directions. The wheel flange lubrication is equipped with a control device 4 which controls the movement of the lubricating pin 2. For this purpose, the control device is connected to the 4 with the power-operated pressing device 3, whereby signals can be transmitted via this connection between the power-operated pressing device 3 and the control device 4, which indicate the movement of the lubricating pin 2 and further signals, for example with regard to the current extension range of the lubricating pin 2 or Faults in the power-operated pressure device 3. The supply of electrical energy to the power-operated pressure device 3 can be done via the control device 4 or by directly connecting the power-operated pressure device 3 to the

    Transmission of control signals 5 to a vehicle control system, via which either the position of the vehicle 5 on the route to the control device 4 or commands for
    Carrying out a lubrication process as well as status or
    Error messages can be transmitted. In Fig.1 is for
    To simplify the illustration, one wheel of a wheel set is shown, but a typical wheel flange lubrication lubricates both wheels of a wheel set, so that the control device 4 also includes a connection to a second power-operated pressing device 3.
