- the transmitter is arranged on a first holding part via a first receptacle and the receiver is arranged on a second holding part via a second receptacle, the respective receptacle and the respective holding part being one or more Form connecting elements or one or more clamping and form-locking connections or an adhesive connection or a welded connection with the component.
- This ensures that the transmitter and receiver are arranged independently of one another on the component, the receptacle for the transmitter and the receiver simultaneously serving as part of the clamp connection.
- a deformation of the receptacle and thus an adjustment of the transmitter or of the receiver is generated during the clamping process.
- the independence of the sender and receiver receptacle or holding part ensures that the component is not subjected to deformation. Neither the sender nor the receiver absorb a force generated by the deformation of the component.
- the receptacle and the holding part have a corresponding fit, the fit being designed as a tongue and groove connection and / or as a dowel pin. Due to the fit, the assembly effort or the adjustment effort of the receptacle on the holding part is reduced to a minimum.
- the receptacle is designed as a claw and is connected to the holding part by means of a pin and / or screw connection, the receptacle and / or the holding part having a clamping element designed as a bolt, screw and / or cam, which with the The component is in operative connection.
- the receptacle can be attached to the holding part independently of the clamping connection. With the independent clamping element, the holder can be held together with the holding part can be moved relative to the component without the connection between the receptacle and the holding part having to be released.
- the receptacle has a holding element for the transmitter and / or the receiver, the holding element being designed as a bore and having a fixing element designed as a cap nut for the transmitter and / or the receiver.
- the training as a precision hole ensures optimal protection for the transmitter or the receiver, which can be inserted into the hole if it is long enough and sunk there.
- the first receptacle for the transmitter and the second receptacle for the receiver have at least one corresponding adjustment surface that can be connected via an assembly aid, the adjustment surface being designed as a groove, bore and / or bevel and the assembly aid with the adjustment surface has corresponding adjustment elements such as a spring or a pin.
- the assembly aid can be used for any recordings and does not have to remain on the device.
- a plurality of receptacles are provided in a measuring area of the component, the receivers being operatively connected via an evaluation unit.
- an additional possibility is that several transmitter-receiver pairs arranged on opposite sides of the component are provided.
- the transmitters and receivers are each provided on opposite sides of the rail, i.e. with respect to the longitudinal axis of the rail on the right and left sides of the rail, and extend over a track section to be measured between 3 m and 30 m.
- a measurement current generated by the receiver is transformed into a measurement voltage within the evaluation unit and that the change in angle on which the voltage change is based is determined between the transmitter and receiver using the following formula:
- the load forces F Q , F ⁇ on which the deformation of the component is based are determined at right angles to the longitudinal direction of the component using the following formula:
- lr 2 is the change in angle of at least two different transmitter-receiver pairs which are arranged on one side and / or opposite one another with respect to the Y direction on the component. It is also advantageous for this that the deformation ⁇ X of the component is proportional to the detected change in angle ⁇ and is recorded as a function of the component length L, the area content of a deformation graph “X over L X ” determined in this way by a
- Averaging ⁇ X 'of all the deformation graphs on which a load cycle is based is standardized and the ratio of the deformation ⁇ X to the standardized deformation ⁇ X' is calculated.
- the graphs deviating from a normal deformation are not taken into account, since they falsify the overall result of the mean load graph. In this way, all influencing variables such as temperature, track bed properties, material properties and basic load of the component are eliminated, so that a representation of a deformation of the component in relation to the basic load is guaranteed.
- the connecting element consists of the holding part which can be placed under the rail foot and a receiving part which is arranged on said rail so as to be vertically movable, at least two screws being able to be screwed into one leg, one screw against the component or the rail foot can be put on and the other screw part establishes a firm connection between the holding part and the component or the rail, the second leg being able to be pressed against the holding part via at least one screw.

- the measuring beam 4 strikes the point E1 of the receiver 3, which represents the zero point. No measurement signal is generated.
- the rail 70 is deformed due to a load F1.
- the transmitter 2 and the receiver 3 are rotated relative to one another by an angle ad1 in accordance with the deflection of the rail 70.
- the measuring beam 4 then strikes the receiver 3 at a point E2 which is at a distance dsl from the point E1. In this way, a measurement signal is generated which corresponds to the distance between the point E1 and the point E2 on the receiver 3 or a receiver surface 3.1.
- the distance which is denoted by dsl according to FIG. 4d, is proportional to the change in angle dal and thus proportional to the change in force dfl between a rest position according to FIG. 4a and the load state according to FIG. 4c.
- the change in position of the measuring beam 4 on the receiver 3 or its receiver surface 3.1 from E1 to E2 is shown.

- a further detection switch 81 ' is then provided. By means of the detection switches 81, 81 ', the speed of the train, the number and the relative position of the wheels can be determined and the measuring section can be activated or deactivated.
- the measurement graph G shown in FIG. 9 a which was determined between two thresholds 75, 75 'or between the centers of the two thresholds 75, 75', is divided into five specific measurement points according to FIG. 9a2.
- the specific measuring points P3 to P7 are used for further signal processing or correlation with a correction graph according to FIG. 9b2.
- FIG. 9 b1 shows a measurement graph G with a first relative maximum R1 and a second relative maximum R2. These relative maxi a are generated due to a flat spot on the wheel and the resulting alternating load on the rail. The flat point leads to a brief drop in the load and thus to a relative minimum F of the graph G.
- a correction graph K is determined from all the graphs representing a good wheel, which is shown in FIG. 9b2.
- the correction graph K resembles an average load cycle of a perfect wheel per sensor and per train crossing and therefore has neither relative maxima nor relative minima.
- FIG. 9cl shows the row of all correction graphs K 1 to K 6 from six successive measuring points.
- the measuring points cover a section of the rail of approx. 3.60 m. This length corresponds to at least one wheel circumference.
- the measuring sections overlap by 100 mm on each side, so that a seamless recording of the load over the entire rail section is guaranteed.
- FIG. 9c2 shows the standard load graphs Nl to N6 generated by the wheel load cycles for each measuring point 1 to 6. About 1/6 of the wheel circumference is shown for each standard load graph N.
- the first half of the measured wheel accordingly has a flat point F, which is followed by an order A according to FIG. 9b1.
- FIG. 9d shows the ratio of the standard load graph N to the correction graph K for a wheel circumference as a load plateau, which ensures a percentage representation of the rail load in relation to the base load.
- the standard load graph N according to FIG. 9e here represents the mean value of all measurement graphs G of a train crossing standardized to the average area. Irregularities of the respective wheel or of the measurement graph G are retained.
- the standard load graph N and the reciprocal of the correction graph K are superimposed according to FIG. 9e and have a common mirror value S, with the aid of which the ratio according to FIG. 9d is determined using the following formula:
- FIG. 9f specific wheel defects per wheel revolution can be recognized on the basis of the generated measurement graphs.
- the application is on the wheel, which initially generates an overload.
- the graph according to FIG. 9e2 is a relatively high-frequency, symmetrical load change that points to polygons.
- FIG. 9e3 shows a typical signal of a wheel out-of-roundness, which leads to a symmetrical graph of low frequency.
- FIG. 9e4 shows a typical flat spot on the wheel, which first generates a drop in load and subsequently an overload.
