Definitions
- the invention relates to a method for controlling the release of lubricant a wheel flange lubrication device of rail vehicles, in which driving and / or route-specific signals recorded and as Control pulses for triggering lubrication processes are used.
- Wheel flange lubrication on rail vehicles pursue the purpose of Wear of the wheel and the rail in the area of the flange reduce. It occurs especially when cornering or swinging when approaching the rail profile to an increased friction and Wear behavior that needs to be reduced.
- the object of the invention is to provide, while avoiding the disadvantages mentioned, an improved method for controlling the wheel flange lubrication of rail vehicles, which allows simple and flexible adaptation with regard to variable lubrication parameters, in order to ensure that lubrication pulses are triggered at the points and at the times. which are to be regarded as optimal in the context of the overall transport.
- a method of the type mentioned is proposed according to the invention, in which time-dependent, path-dependent, arc-dependent and / or route-programming-dependent signals are picked up by signaling devices, such as contacts, transmitters or sensors, optionally individually, together or in any combination, in which the signals are evaluated in a computing unit for a freely programmable control, and from which the triggering of lubrication processes is derived in accordance with the route-specific, temporal and quantitative lubrication specifications, the lubrication specifications being variably adjustable.
- digital and analog signals are recorded and processed, so that with regard to the no restrictions on the wheel flange lubrication devices used given are.
- the time-dependent control expediently uses the Lubrication processes triggering a lubrication pulse after a free one selectable and programmable pause time, at which also Downtimes of rail vehicles are taken into account ensure economical and ecological use of the lubricant.
- Further procedural design is the path-dependent Control of the lubrication processes after the triggering of a lubrication pulse made a freely selectable and programmable route, whereby the distance covered is determined from the measured driving speed is, so that a complex direct route detection is avoided can be.
- the arc-dependent control of the Lubrication processes trigger the lubrication pulse with the help of a Arc-recognizing signal generator with variable sensitivity made so that a variable adjustment to the respective Operating conditions is guaranteed.
- a Arc-recognizing signal generator with variable sensitivity made so that a variable adjustment to the respective Operating conditions is guaranteed.
- arc detection preferably as a centrifugal switch, Inclination angle sensor or light barrier implemented signal transmitter used and that when an arc is detected, it is only ever on the outer side wheel flange lubrication is carried out on the curve, causing one economic lubricant consumption is taken into account.
- the duration of the lubrication is expediently dependent on Lubrication pulse controlled so that the respective circumstances an optimal amount of lubricant is available.
- Fig. 1 shows schematically a wheel flange lubrication device with which The inventive method can be carried out. Can be seen two different variants for wheel flange lubrication.
- the above in Fig. 1 illustrated embodiment is intended for standard rails, while the embodiment shown below is applied to grooved rails, with any desired combination of time, path, arc and route-dependent control by means of an integrated Control device 4, the signals provided by sensors or sensors used to trigger lubrication pulses, can be realized, so that a simple adaptation to all operational requirements of the different types of use is guaranteed.
- the right in Fig. 1 from the Part of the device shown perpendicular wavy line is identical usable in both embodiments.
- the lubricating device itself consists of a lubricant container 1, in which oil with an operating viscosity of 100 mm 2 / s to 1000 mm 2 / s or fluid grease or a biodegradable lubricant is arranged as a lubricant, a compressed air source D with an inlet pressure of maximum 10 bar, through which the lubricant stored in the lubricant container 1 is pressurized with compressed air via a ventable shut-off valve 7 and a pressure regulator 8, a lubricant line 2, a compressed air line 9, an electrical line 10, one or more lubricant metering pumps 3, one or more flow dividers 11 and one (embodiment "standard rail”) or two (embodiment "grooved rail”) lubricant-air mixture lines 5 and spray nozzles 6.
- the lubricant passes via the lubricant line 2 to the lubricant metering pump or pumps 3, which in addition via the compressed air line 9 to the Compressed air source D is connected or s ind and via the electrical line 10 receives or receive the lubrication pulses of the control device 4.
- the lubricant metering pump 3 designed here as a piston metering pump 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.
- In the housing 12 are coaxial with each other Delivery piston 16 and a control piston 17 are arranged, the pump element form and are each spring-loaded.
- the delivery piston 16 is actuated and the control piston 17 by an electromagnet 18 which is connected to the Pump housing 12 is flanged with the help of cheese head screws.
- the electromagnet 18 to the control unit 4 via the corresponding electrical cable 10th
- the delivery piston 16 In the rest position of the metering pump, the delivery piston 16 is driven by its Compression spring against the support bushing 21 and visible on the left in the drawing the control piston 17 against the pump housing 12 by its compression spring pressed to their left end position.
- the lubricant connection 13 About the lubricant connection 13 is the metering pump 3 fed lubricant under pressure and thereby the space between the delivery piston 16 and the control piston 17 with 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 to the mixing chamber of metering pump 3 interrupted.
- the delivery piston 16 By actuating the electromagnet 18 by means of the control device 4 the delivery piston 16 is shifted to the right against its compression springs. After the delivery piston 16 has closed the suction bore, the trapped lubricant between the delivery piston 16 and the Control piston 17 moved to the right until the control piston 17 releases the pressure channel to the outlet. The ball is shortly before the end position 19 of the check valve against the compression spring 20 from its valve seat on O-ring 22 displaced to the right by the control piston 17. As a result, the path of the compressed air to the mixing chamber and outlet 15 Approved. After the control piston 17 has released the pressure channel, is the lubricant through the delivery piston 16 via the pressure channel in the Mixing chamber pushed out. The mixes in the mixing chamber Compressed air with the lubricant and the compressed air transports the Lubricant to the spray nozzle 6.
- the control unit 4 which is a programmable electronic computing, Storage and processing unit with cyclical program processing contains, via the electrical line 10 in the lubricant metering pump 3rd Triggered lubrication pulses lead to the release of a defined one Lubricant amount, while the compressed air supply from the Compressed air source D via the compressed air line 9 in the lubricant metering pump 3 is opened.
- the compressed air transports the lubricant as a lubricant-air mixture either directly or via a flow divider 11 through the Lubricant-air mixture line 5 to a near the flange arranged spray nozzle 6 in order to apply the lubricant to the spray on the respective flange of the rail vehicle.
- the Lubrication pulses are dependent on the input signals time-dependent and / or path-dependent and / or arc-dependent and / or provided depending on the route programming, whereby for all Wheel flange lubrication systems that use an arc-dependent control subject to two lubricant dosing pumps 3 are always used Only lubricate the corresponding outer side when cornering.
- the control system is designed so that even small amounts of lubricant between 10 mm 3 and 50 mm 3 can be distributed homogeneously in the compressed air in a rapid cycle sequence to the lubricant nozzle, the pause time between two lubrication pulses being just as variable as the distance between two lubrication pulses and whereby additional lubrication pulses are possible by means of arc-dependent and / or route-programming-dependent signals.
- the time-dependent control of the lubrication processes is activated Lubrication pulse after a freely selectable and programmable Pause time triggered when the signal for release is available. Downtimes of the rail vehicles are also taken into account, so that only the real operating time is used.
- the path-dependent Control of the lubrication processes will release a lubrication pulse after one selectable and programmable distance triggered.
- the covered Path is calculated from the measured driving speed.
- the Entry into an arc is preferably carried out as a centrifugal switch, Tilt angle transmitter or light barrier implemented signal transmitter recognized, so that with the present release on the corresponding side of the vehicle a lubrication pulse can be triggered.
- control device 4 is further designed so that it optionally one or two dosing pumps 3 depending on the Control and monitor input signals.
- a fault indicator relay picks up and the inputs are polled cyclically by the computer.
- the control is released, for example by a reversing switch and a predetermined one Minimum speed monitoring signal transmitters are carried out by the Control unit 4 initiated sprays of lubrication caused by the direction of travel selected dosing pump 3 with each pulse of an existing signal.
