The invention relates to a deformation tube for a coupling, in particular Zugkupplung with two against a resistance telescoping pipe parts; with a securing element in the form of a screw or a nut, which is screwed into a counter-element or screwed onto a counter-element and thereby braced the two pipe parts against each other. The invention is characterized by a detection device which is set up to detect a rotation and / or an axial displacement of the securing element and / or the counter-element relative to at least one of the two tube parts.
The present invention relates to a deformation tube for a coupling, in particular traction coupling and a traction coupling with such a deformation tube.
The previous monitoring is, as shown, limited to detect whether one of the two pipe parts of the deformation tube has been inserted axially into the other of the two pipe parts. Although this detection also only a temporary critical deformation of the deformation tube is detected, but there are other safety-related components of the deformation tube, the condition of which has an effect on the functioning of the deformation tube. Thus, the two against a resistance telescoping pipe parts are braced against each other. For this purpose, a nut is conventionally provided, which is screwed onto a tie rod. The tie rod is fixed in one of the two tube parts and extends in the longitudinal direction of the tube parts through an end face of the other tube part. The nut is screwed onto this end, which is guided through the end face, so that the two tube parts are braced against the mentioned resistance, which precludes telescoping. If now releases the mother, the tension is inadequate and the two pipe parts can be adjusted from the desired orientation to each other. Conventionally, therefore, from time to time, the mother or its seat is controlled on the thread by means of an endoscopy camera, which is expensive and is associated with restrictions on the control accuracy. In addition, there is the danger that a release of the mother is not recognized over a long time.
The present invention has for its object to provide a deformation tube for a coupling, in particular traction coupling of the generic type, which is improved in terms of its safety over the known embodiments.
The object of the invention is achieved by a deformation tube having the features of claim 1. In the dependent claims advantageous and particularly expedient embodiments of the deformation tube and a traction coupling are given.
An inventive deformation tube for a coupling, in particular a traction coupling, has two pipe parts which can be pushed into one another against a resistance. For example, the resistance is formed in that the first tube part - inner tube part - is inserted with an axial end in a radial expansion at the opposite axial end of the second tube part - outer tube part, such that the first tube part end face in the radial extension on the second Pipe part strikes. At the interface can on the first pipe part optionally still be connected a sliding element. By means of a sufficient axial force, when the deformation tube is triggered, the inner tube part is then pushed further against the outer tube part, so that the outer tube part expands, whereby energy is consumed.
The deformation tube according to the invention has a securing element in the form of a screw or a nut, which is screwed into a counter-element or screwed onto a counter-element and thereby braced the two tube parts against each other. For example, the counter element is a tie rod, which is connected with its first end to a first of the two pipe parts, for example, the outer pipe part, or a structure carrying the first of the two pipe parts and having a second end, which is opposite to the first end, an end face penetrates the second of the pipe parts and end of the penetration has a thread on which the securing element is screwed in the form of a nut. Accordingly, the nut is located radially inside the second pipe part, in particular of the inner pipe part.
According to the invention, a detection device is now provided, which is set up to detect a twisting and / or axial displacement of the securing element and / or of the counter element relative to at least one of the tube parts.
By the detection device, it is possible to early detection of a loosening of the securing element, in particular in the form of the mother and possibly to signal a train driver or other maintenance personnel.
For the design of the detection device various possibilities come into consideration, including mechanical and electrical solutions, which may optionally be combined with each other. To implement a mechanical solution, for example, the detection device may comprise at least one shearing element, which is connected through a bore, in particular radial bore, in at least one of the two tube parts on the securing element and / or the counter element such that a relative rotation and / or displacement of the Securing element relative to the tube part causes a shearing off of the shear element of the securing element and / or counter element or a shearing within the shearing element. For example, such a shearing element is provided only in a bore, in particular a radial bore, in the inner tube part and connected to the securing element, in particular in the form of a nut. In addition or as an alternative, however, such a shearing element can also be provided in a bore, in particular likewise in the inner tube part, but possibly also in the outer tube part, and be connected to the counter element, which is designed, for example, in the form of the tie rod. Thus, both a displacement and especially a twisting of either the nut or the tie rod can lead to an unwanted release of the tension of the two pipe parts against each other.
For example, the at least one shear element with a clearance in the respective bore, in particular radial bore, is used. This allows a certain tolerance to be achieved before the shearing element is sheared off.
According to one embodiment, the shearing element is glued to the securing element and / or the counter-element. In this case, it is advantageous to leave the shearing element in the glued connection if the displacement or rotation which is to be detected occurs.
Another mechanical solution provides that the detection device has only one visible marking on the securing element and / or the counter element and the corresponding one of the two tube parts facing the marking comprises, at the corresponding opposite position, an inspection opening through which the marking can be seen , If now the mark is no longer aligned in the originally predetermined relative position relative to the inspection opening, in particular no longer aligned centrally relative to the inspection opening, it can be concluded solely by visual inspection on an undesirable rotation and / or displacement of the securing element and / or counter-element.
The marker may be, for example, a color marker.
For example, the inspection port may be sealed with a transparent plug or removable plug to prevent dust and / or other debris from entering the deformation tube through the inspection hole.
In an electrical solution, the detection device may comprise at least one optical and / or electrical sensor which is mounted in at least one of the two tube parts and detects a rotation and / or axial displacement of the securing element and / or the counter element. For example, here also a bore, in particular radial bore is provided in at least one of the two tube parts and the optical and / or electrical sensor is in this Bore or through this hole mounted. According to a possible embodiment, a closure body for the bore on the sensor. Another embodiment provides that the sensor is attached to an inner side of the corresponding pipe part and faces the securing element or counter element.
The energy supply of the sensor can be done locally by a battery or a battery and / or by the electrical supply of the train when used in a traction coupling. Furthermore, there is also the possibility of energy harvesting, i. the extraction of small amounts of energy from the environment, such as ambient temperature, vibration, etc.
For example, in the electrical configuration on the securing element and / or the counter-element on the outer surface of an electrical and / or optical encoder may be provided. Such an encoder can be formed by an electrical and / or optical transmitter, but alternatively also simply by a marking, for example in the form of coded strips or the like. The sensor can then detect the position and / or signal strength of this encoder and detect therefrom a rotation and / or axial displacement of the encoder and thus the securing element and / or the counter-element.
In particular, in order to carry out an early warning system and / or for easier maintenance of the deformation tube or the corresponding traction coupling can be connected wirelessly or wired to the sensor, a visual or audible display device to signal a detected twisting and / or moving the fuse element and / or the counter element. Corresponding warning signals can be signaled to the driver, for example. Alternatively, it is possible to store corresponding signals in a control unit retrievable. It is also possible to provide a warning lamp in the region of the deformation tube, for example on the sensor, but also outside the region of the deformation tube, for example in the train driver's station, which indicates a response of the sensor.
A clear signaling of the response can be achieved in a mechanical solution, for example, by the fact that said shearing element, which is generally designed in particular in the form of a pin, falls out of the bore in the tube part during shearing off the securing element or the counter element. Optionally, the shearing element for even clearer signaling for this purpose have a different color than the pipe part.
The electrical sensor can be designed both as an inductive or as a capacitive sensor. It is also conceivable training as a magnetic or optical sensor. In general, various electrical embodiments are conceivable.
According to one embodiment of the invention, the electrical and / or optical sensor can be mounted on a support element which is deformed, destroyed and / or torn off during rotation and / or axial displacement of the securing element and / or the counter element, so that the electrical and / or optical sensor is removed from its predetermined position. This removal is detected by the sensor, for example due to a change in capacitance, inductance or the interruption of an electrical current flow. Other possibilities come into consideration, for example, with the removal of the sensor from its position an optical or electrical signal is no longer received.

In the 1 is a deformation tube 1 shown with a first pipe part 2 and a second pipe part 3 , The first pipe part 2 is designed as an inner tube part, has at one axial end Slide 4 on and is with this slider 4 in a radial expansion 5 of the second pipe part 3 used, which is designed as an outer tube part. Another axial insertion of the first pipe part 2 in the second pipe part 3 is only with a simultaneous deformation of the second pipe part 3 possible.
The first pipe part 2 and the second pipe part 3 are clamped in their initial position in the axial direction against each other. This is a fuse element 6 provided, which is designed in the form of a nut, on a counter element 7 is screwed in the form of a tie rod. Other embodiments for clamping the two pipe parts 2 . 3 together are possible. For example, the fuse element could 6 be executed in the form of a screw in the counter element 7 is screwed in the form of a nut or other threaded component.
In one of the two pipe parts, here in the first pipe part 2 is at least one radial bore 8th . 9 brought in. One of the two radial bores 8th . 9 can be enough. However, both radial bores can 8th . 9 be provided.
The radial bore 8th is in that section of the first pipe part 2 provided that the fuse element 6 encloses. The radial bore 8th is therefore the fuse element 6 in the radial direction opposite.
The radial bore 9 is in each section of the first pipe part 2 provided, which the counter element 7 encloses. Accordingly, the radial bore 9 the counter element 7 in the radial direction opposite.
Through the radial bore 8th may be a twisting and / or axial displacement of the securing element 6 be captured by the radial bore 9 can be a twisting and / or axial displacement of the counter element 7 be recorded. This is done in the appropriate radial bore 8th . 9 a detection device used, or provided in the corresponding area.
The 2 to 8th show exemplary embodiments of the detection devices 10 , in each case in connection with the radial bore 8th , However, appropriate detection devices 10 also in the field of radial drilling 9 from the 1 be provided to prevent twisting or axial displacement of the counter element 7 capture. In addition, other positions of the detection device 10 possible.
In the 2 includes the detection device 10 a shearing element 11 , here in pen form or tube shape, attached to the fuse element 6 with an adhesive 12 is glued on. Instead of sticking, it would also be possible to choose another substance-liquid compound, for example soldering or welding.
The shearing element 11 protrudes from the fuse element 6 through the radial bore 8th through, with the radial bore 8th in particular, has a larger inner diameter than the area enclosed by it of Abscherelementes 11 , so a game between the shear element 11 and the first pipe part 2 is provided and a shearing of Abscherelementes 11 only after bridging this game when turning or axial displacement of the fuse element 6 he follows.
The embodiment according to the 3 corresponds to that of 2 , only here the shear element 11 in a thread 13 in the fuse element 6 is screwed. In both cases becomes advantageous in the case of dissolution of the detection device 10 the shear element 11 from the fuse element 6 sheared off and falls out of the radial bore 8th out.
In the embodiment according to the 4 has the detection device 10 a mark 14 on the fuse element 6 on, the one inspection opening 15 facing in the radial direction. The inspection opening 15 gets through the radial opening 8th is formed and is by a lock 16 locked. The closure 16 is transparent, for example, or comprises a transparent window and / or is removable in the inspection opening 15 assembled. Thus, through the inspection opening 15 be detected by visual inspection, whether the fixed on the fuse element 6 applied mark 14 has moved. If necessary we use a flashlight 27 taken to the rescue.
In the embodiment according to the 5 takes the radial bore 8th a sensor 17 on, which is designed here as an optical sensor, in particular as an optical motion sensor. The sensor 17 is a giver or a mark 18 on the fuse element 6 assigned such that the sensor 17 a change of position or movement of the encoder or marking 18 detected.
For example, the sensor has 17 a warning light 19 which indicates when a position change or movement has been detected.
In the embodiment shown, the sensor 17 an own electrical energy supply 20 on.
In the embodiment according to the 6 is also a sensor 17 provided, the rotation and / or axial displacement of the securing element 6 detected. The sensor 17 However, is different from the embodiment according to the 5 representing a local solution via lines 21 (or wirelessly) to a controller 22 , which is for example on the train, in particular in the driver's compartment of the train, connected. The control unit 22 in turn controls a display device 23 in particular also positioned in the driver's compartment.
In the embodiment according to the 7 becomes the sensor 17 from a support element 24 carried in mechanical connection with the securing element 6 and / or the counter element 7 is and by a rotation and / or axial displacement of the fuse element 6 or the counter element 7 is destroyed, deformed or moved, causing the position of the sensor 17 changes. The sensor 17 is arranged to detect this change in position, for example, in which a capacitive coupling or an electrical contact with the fuse element 6 or the counter element 7 is interrupted or changed and this from the sensor 17 is detected. Incidentally, the sensor can 17 be integrated again in the form of a self-sufficient local solution or to a train provided in the control unit analogous to the embodiment according to the 6 be connected.
In the embodiment according to the 8th is the sensor 17 as a color sensor running through the radial bore 8th through a mark 18 on the fuse element 6 detected. Alternatively for color sensors are magnetic, capacitive or inductive sensors. In particular, other sensors can be used to monitor the acceleration and temperature in the sensor 17 be integrated, here exemplified using the temperature sensor 25 and the acceleration sensor 26 ,
