Definitions
- the invention relates to a method for monitoring the area of technical rolling bodies, in particular their documents, in which forces occurring there are detected with sensors in order to generate electrical energy, in order to change the state of the area by means of an electrical control and evaluation station, such as material and separation damage to detect, according to the preamble of claim 1 and a device therefor according to the preamble of claim 3.
- Such a method for generating electrical energy in the area of moving technical rolling elements is known from DE 43 35 776, the anelastic deformations causing the rolling friction and the forces occurring in the area of the bearing or rolling points of the rolling elements being transmitted periodically to electromechanical transducers and thereby at least partially converted into electrical energy.
- the impulses introduced by rolling the rolling elements in their area are detected with sensors arranged there in order to generate electrical energy and generally to detect changes in state.
- the device is also used to monitor technical rolling elements by means of a control and evaluation device for technical devices, the rolling properties of the technical rolling elements being derived from the electrical energy, so that appropriate safety measures can be taken in the event of deviations in this electrical energy.
- electromechanical transducers are arranged in the effective areas of the periodically changing rolling frictional forces of technical rolling bodies and / or their documents. The forces are transferred to transducers and thereby converted into electrical energy, whereby the rolling properties of technical rolling elements - 2 -
- this electrical energy in addition or on its own, are to be derived and can thus be checked at a corresponding device.
- DE-Al-39 37 966 has disclosed a method and a device for determining the adhesion conditions between vehicle tires and the road.
- At least one sensor is arranged in the tire protector, which detects the courses of the local stresses or strains or deformations in the horizontal direction and in the normal direction when passing through the tire flap.
- the measurement signals from the sensor are transmitted to an evaluation device.
- both the currently claimed adhesion coefficient and the maximum possible adhesion coefficient between the vehicle tire and the road are determined from these measurement signals. No rolling friction forces are measured with this method.
- a method for determining the frictional torque of a measuring bearing in which one rotates a bearing ring of the measuring bearing at a constant speed, while the other bearing ring is connected via a measuring head to a spring acting as a force transducer, the force transducer being a Generates signal as a measure of the friction torque of the measuring bearing and dampens the movement of the measuring head force transducer system as little as possible.
- the measuring bearing is replaced by an air bearing, a signal proportional to the spring deformation and a signal proportional to the acceleration of the measuring head being generated in this air bearing arrangement and a further signal being derived therefrom.
- the signals obtained are summed up, the result being a measure of the friction torque that occurs.
- the invention is based on the object of further developing such a method and a device that changes in state occurring in the field of technical rolling elements can be detected at any time using sensors. - 3 -
- the object is achieved according to the invention in a method of the type mentioned at the outset in that at least one of the sensors arranged in the area of the technical rolling bodies is actively supplied with electrical energy and in the process initiates evaluable pulses as an actuator into its base, of which in the area of the technical rolling bodies arranged sensors can be detected at any time and thus the area of the technical rolling elements is monitored for changes in state at any time.
- the area of the technical rolling elements, in particular the support, for example a rail, can thus advantageously be monitored at any time for changes in state.
- At least one of the sensors working as a transducer in the area of the technical rolling elements is acted upon with electrical energy and in the process initiates evaluable pulses as an actuator sensor in its base, so that at any time with the further sensors arranged in the area of the technical rolling elements evaluable electrical impulses can be detected, from their evaluation changes in state can be read and this area must be monitored at any time.
- the actuator sensor can be supplied with electrical energy by any energy source that is activated, for example, by a control and evaluation station.
- the initiation of the impulses in the field of technical rolling elements is achieved in that the actuator, excited with electrical energy, of the transducer working as an impulse transmitter, for example, introduces mechanical waves into its base, for example a rail, and thus with those in the field of technical ones Rollers arranged transducers the impulses are to be recorded at any time.
- the actuator, excited with electrical energy, of the transducer working as an impulse transmitter for example, introduces mechanical waves into its base, for example a rail, and thus with those in the field of technical ones Rollers arranged transducers the impulses are to be recorded at any time.
- changes in condition such as damage to materials and separation can thus be detected and signaled at any time.
- Electromechanical transducers are used as actuator sensors, which detect pulses on their base and which are subjected to electrical energy as .actuators or generators to generate corresponding pulses, for example elastic waves, on the base or to signal such pulses complementarily from there are able to.
- the distances and the performance of the sensors working as actuators or as transducers depend on the distances to be covered or the intensities required to transmit the pulses to / in their documents and can be determined in advance.
- identically constructed or different transducers can be operated both as pulse receivers and as pulse transmitters in the area of the technical rolling elements, and thus mechanical or electromagnetic waves can be introduced into the base of the actuator sensors at any time.
- All active powers, or transmissions of the necessary input, output and test signals from or to the actuator sensors, or the converter can be carried out in a conventional manner, e.g. by means of galvanic elements - such as cables etc. - and / or, at least in part, can be carried out wirelessly, in this case the installation of conventional transmission elements can be dispensed with.
- Piezo sensors for example, are proposed as transducer sensors, the parts of which move in vibration as actuators touch the base of technical rolling elements or operate an impulse hammer during the respective stroke reversal.
- a device for monitoring the documents of technical rolling bodies, in which occurring forces are detected there with sensors and signaled to a control and evaluation station, is characterized in that at least one of the sensors arranged on the substrate can be acted upon by electrical energy and thereby the sensor, as a pulse transmitter, introduces evaluable pulses into the base, so that the sensors on the base can be used to record, at any time, evaluable pulses when monitoring the area of technical rolling elements as pulse receivers and signal them to a control and evaluation station as required.
- the advantages achievable with the invention consist in the fact that with the method according to the invention the area of technical rolling elements can be reliably and inexpensively monitored for material and separation damage, in particular vehicle rails for high-speed railways.
- the pulses introduced with the actuator sensors operating as pulse transmitters can be designed for a known target value, for example determined by measurement. If the incoming actual value of the pulses at the sensors working as a pulse receiver deviates from the known value, conclusions can be drawn as to the extent of the damage that has occurred or begins in the area of the technical rolling element underlay, at any time during a control measurement against effects of damage and regardless of the movement of the rolling body.
- Impulse hammer can work or which can directly drive such an impulse hammer and which can be additionally or individually evaluated

- the transducer 2 introduces physically evaluable pulses 5b into the base 1, which is detected by a sensor 3, which also functions as a transducer, such as test signal receiver 3 or pulse generator-pulse receiver 3, on or in this base 1 and from there as electrical signals 5c a control and evaluation station are signaled, for example galvanically coupled or by means of a radio link.
- the receiving control and evaluation station can be identical to the control and evaluation station 6.
- Converter 2 and converter 3 can also be constructed identically.
- FIG. 2 shows a stretched base 1, such as rail 1, as a region of a technical rolling body (not shown) in supervision, with an actuator sensor 4 or transducer 4 arranged on the base 1 and functioning as a module, which is provided by a control and evaluation station 6
- Electrical energy 5a acts as a transmitter, initiates pulses 5b into the base 1 and at the same time as the receiver detects all the removable pulses 5b on the base 1 and transmits them as electrical signals 5c to a control and evaluation station, the receiving control and evaluation station again using the sending control and evaluation station 6 may be identical.
- Fig. 3 shows a stretched pad 1, such as rail track 1, on which a technical rolling element 7, such as vehicle wheel 7, moves in a side view, on the

- pulses 5a can be applied to a pulse generator-pulse receiver 2 or converter 2 located on or in the base 1, which in turn initiates pulses 5b into the base 1, which leads to one further transducers 3 located on or in the base 1 are routed, picked up by the latter and transmitted as electrical signals 5c to the control and evaluation station 6.
- Converter 2 and converter 3 can in turn be constructed identically.
- signals from the control and evaluation station 6 can be fed to the test signal sensors 8 within the rolling element 7; for example, the control and evaluation station 6 conducts electrical energy into the test signal sensors 8, which in turn initiate evaluable pulses 5a 'into the converter 2, which in turn emits signals 5b which spread in the base 1 and are received by the converter 3 and either as a signal 5c are passed directly to the control and evaluation station 6 or as a signal 5c 'to the test signal sensors 8, which in turn forward or transmit the signals to the control and evaluation station 6.
- the pulses can be transmitted wirelessly from or to the control and evaluation station 6, the stationary control and evaluation station 6, or also a mobile control and evaluation station, at least partially being one operated by radio technology.
- the pulses from the transducer 2, which are introduced into the base 1 after it has been excited, are detected by the transducer 3 after passing through the pulses over a certain distance on or in the base 1 and from there or from the transducer 3 a stationary or mobile control and evaluation station 6 signals.
