Definitions
- the invention relates to a method for controlling the release of lubricant Wheel flange lubrication device of rail vehicles, in which driving and / or route-specific signals are recorded and used as control pulses to trigger Lubrication processes are used.
- Wheel flange lubrication on rail vehicles pursue the purpose of wearing out the Reduce wheel and rail in the area of the flange. Especially with Bends or pendulum movements occur when the rail profile is started an increased friction and wear behavior that needs to be reduced.
- DE-A-2617993 as the closest prior art describes a method of known type, in which the lubricant in the form of grease and Compressed air is transported to the lubrication point via separate lines, whereby to Control of the lubricant delivery as parameters depending on the path or on the arc Signals from signaling devices arranged on the rail system can be used.
- the object of the invention is to avoid the aforementioned Disadvantages of an improved method for controlling the wheel flange lubrication
- the one with regard to changeable lubrication parameters simple and flexible adjustment allows to trigger lubrication pulses on the Make and ensure at times that are considered as part of the overall promotion are optimal to look at.
- digital and analog signals can be recorded and processed, so that with regard to the used Wheel flange lubrication devices are not subject to any restrictions.
- the time-dependent control of the lubrication processes Triggering of a lubrication pulse after a freely selectable and programmable one Break time is carried out, including downtimes of the rail vehicles be taken into account to ensure economical and ecological use of the lubricant ensure.
- the path-dependent Control of the lubrication processes triggering a lubrication pulse after a free selectable and programmable distance, the distance covered is determined from the measured driving speed, so that a complex direct Distance detection can be avoided.
- the arc-dependent control of the lubrication processes is advantageous Triggering of the lubrication pulse with the help of an arc recognizing in its Sensitivity variable signal transmitter made so that a variable adaptation to the the respective operating conditions is guaranteed.
- arc detection preferably as a centrifugal switch, Tilt angle sensors or light barriers are used and that when an arc is detected, only one on the outer side of the curve Wheel flange lubrication is made, making an economical Lubricant consumption is taken into account.
- Fig. 1 shows schematically a wheel flange lubrication device with which the invention Procedure can be carried out. Two different variants can be seen Wheel flange lubrication.
- the embodiment shown in Fig. 1 above is for Standard rails are provided while the embodiment shown below Grooved rails is used, with any desired combination of time, path, arc and route programming-dependent control by means of an integrated control device 4, that the signals provided by sensors or sensors to trigger Lubrication pulses can be realized, so that a simple adjustment to all operating requirements of the most varied types of use are guaranteed.
- the in Fig. 1 part of the device shown to the right of the vertical wavy line is identical usable in both embodiments.
- the lubrication device itself consists of a lubricant container 1, in which as Lubricant Oil with an operating viscosity of 100 mm2 / s to 1000 mm2 / s or fluid grease or a biodegradable lubricant is arranged as a supply, one Compressed air source D with an inlet pressure of maximum 10 bar, through which the Lubricant reservoir 1 stored lubricant via a bleed stopcock 7 and a pressure regulator 8 is pressurized with compressed air, a lubricant line 2, one Compressed air line 9, an electrical line 10, one or more Lubricant metering pumps 3, one or more flow dividers 11 and one ("Standard rail” embodiment) or two (“Grooved rail” embodiment) Lubricant-air mixture lines 5 and spray nozzles 6.
- Lubricant Oil with an operating viscosity of 100 mm2 / s to 1000 mm2 / s or fluid grease or a biodegradable lubricant is arranged as a supply
- the lubricant passes through the Lubricant line 2 to or the lubricant metering pumps 3, which additionally via the Compressed air line 9 is or are connected to the compressed air source D and via the electrical line 10 receives or receive the lubrication pulses of the control device 4.
- the one here designed as a piston metering pump Lubricant metering pump 3 consists of a pump housing 12 with a connection 13 for the lubricant, a connection 14 for the compressed air and an outlet 15 for the Lubricant-air mixture.
- a feed piston 16 is coaxial to one another in the housing 12 and a control piston 17, which form the pump element and each are spring loaded.
- the delivery piston 16 and the control piston 17 are actuated by an electromagnet 18 attached to the pump housing 12 by means of cheese head screws is flanged.
- the electrical connection of the electromagnet 18 to the control unit 4 takes place via the electrical line 10 provided with a corresponding plug.
- the delivery piston 16 In the rest position of the metering pump, the delivery piston 16 is actuated by its compression spring against the support bushing 21 and the control piston 17 which can be seen on the left in the drawing his compression spring pressed against the pump housing 12 in their left end position. about the lubricant connection 13 is fed to the metering pump 3 lubricant under pressure and thereby the space between the delivery piston 16 and the control piston 17 Lubricant filled.
- the ball 19 of the check valve is by the compression spring 20th pressed against the valve seat of an O-ring 22. This will make the compressed air supply interrupted to the mixing chamber of the metering pump 3. Pressure stroke By actuating the electromagnet 18 by means of the control device 4 Delivery piston 16 moved against its compression springs to the right.
- the by the control unit 4, which is a programmable electronic computing, storage and processing unit with cyclic program execution contains, via the electrical Line 10 in the lubricant metering pump 3 triggered lubrication pulses lead to Release of a defined amount of lubricant, while at the same time the compressed air supply from the compressed air source D is opened via the compressed air line 9 in the lubricant metering pump 3 becomes.
- the compressed air either transports the lubricant as a lubricant-air mixture directly or via a flow divider 11 through the lubricant-air mixture line 5 a spray nozzle 6 arranged in the vicinity of the wheel flange in order in this way to Spraying lubricant on the respective wheel flange of the rail vehicle.
- the Lubrication pulses are time-dependent and / or dependent on the input signals path-dependent and / or curve-dependent and / or route programming-dependent
- the one sheet-dependent control always two lubricant dosing pumps 3 can be used to lubricate only the corresponding outer side when cornering.
- the control is designed so that even small amounts of lubricant between 10 mm3 and 50 mm3 homogeneous in the compressed air is distributed in a rapid cycle of the lubricant nozzle Allow the pause time between two lubrication pulses is also variable is adjustable how the distance between two lubrication pulses and additional Lubrication pulses through arc-dependent and / or route-dependent signals possible are.
- a lubrication pulse is emitted during the time-dependent control of the lubrication processes Expiry of a freely selectable and programmable pause time triggered when the signal is available for approval. Downtimes are also taken into account Rail vehicles, so that only the real operating time is used.
- the A lubrication pulse is released after a path-dependent control of the lubrication processes selectable and programmable distance triggered. The path covered calculated from the measured driving speed. Retracting into an arch is preferably used as a centrifugal switch, inclination angle sensor or light barrier executed signal generator detected, so that with the present release on the A lubrication pulse can be triggered on the corresponding side of the vehicle. On off an individual route programming signal is given at the route programming-dependent control.
- control unit 4 is further designed so that it is either a or Control and monitor two dosing pumps 3 depending on the input signals can.
- a fault indicator relay picks up and the The computer polls inputs cyclically.
- control unit 4 initiated spray lubrication pulses of the metering pump 3 selected by the direction of travel every pulse of a present signal.
