Definitions
- Connection element for a coupling element of an air coupling for use in pull couplings, in particular automatic pull couplings
- the invention relates to a connecting element for a coupling element of an air coupling for use in pull couplings, in particular automatic pull couplings, in particular with the features from the preamble of claim 1.
- Air couplings for automatic train couplings are known, for example, from Knorr-Bremse GmbH: Automatic train couplings. This is located in the coupling head of an automatic train coupling below the longitudinal axis of the coupling and is in the starting position with the sealing surface in front of the coupling center. It consists of an air tube and a sealing ring as well as concentrically arranged gripping elements which, when coupled, that is to say when they interact with a complementary coupling element of an air coupling of a rail vehicle to be coupled to a rail vehicle, and ensure tightness under vacuum and overpressure. The air couplings are pushed back during the coupling process until the gripping elements are centered.
- a pre-compression spring is arranged on the air coupling elements, in particular the air tube, which presses the air tube into the corresponding position.
- the coupling profiles initially move transversely to the longitudinal axis of the coupling.
- the opening contours of the coupling heads hit the air coupling grippers and unhook them.
- the rear of the air coupling is designed in such a way that it can be connected to a half-shell coupling used.With mixed coupling of vehicles with an automatic pull coupling and vehicles with a screw coupling, this half-shell coupling can be unhooked and connected to the air hose of the screw coupling carriage.
- the air coupling can be used to replace the sealing ring Coupled coupling heads are removed to the rear, for which purpose a bearing pin must be pulled out.
- the invention was therefore based on the object of further developing a connecting element for air couplings, in particular an air coupling element on a rail vehicle, in such a way that the disadvantages mentioned are avoided, in particular that verifiability is achieved despite the arrangement of the air coupling head on the train assembly. Escaping the air at the last air coupling head should also be avoided.
- connection element for an air coupling element of a coupling comprising an air tube and gripping elements arranged concentrically to the latter, has an air guide tube which can be inserted into the air tube, the air guide tube having a stop surface on which a sealing device is arranged, which is connected to the sealing device of the air pipe interacts.
- connection element has a head element which, depending on the application, is designed differently to implement different functions. Means are provided which securely connect the connecting element to the air coupling element under the action of compressed air. tion elements, which use the existing surfaces on the gripping elements of the air coupling element for support and in the test state, that is to say under pressure, lock the connecting element with respect to the gripping elements.
- the connecting element is first brought into a position in which compressed air can escape by means of a lever position on the locking element.
- the hooking can only be released after relief.
- the second embodiment is characterized in that the inclined plane of the gripping elements on the air coupling head is used in such a way that the connecting element cannot be released by hand as long as the air line is under pressure.
- a hook element is provided in this case, which must be released by hand before unlocking.
- connection elements cannot fly away even when operating incorrectly using force
- connection element In a further aspect of the invention, depending on the design of the head elements, different functions can be implemented with the connection element. These include:
- the coupling head is complementary to the coupling element of a half-shell coupling, so that an interaction between the head element of the connecting element and the coupling element of a half-shell coupling can be guaranteed.
- the head element is designed in such a way that in the locked state of the connection element with the air coupling it ensures a safe interaction with the half-shell coupling.
- the head element is designed as a blind closure, with a large number of possibilities also here. These include:
- the head element as a connecting flange element of the air guide tube, the flange element closing the air guide channel in the air guide tube or
- the head element closes the guide channel in the air guide tube or
- FIGS. 1 a and 1 b illustrate in two views an inventive connecting element in the form of an adapter according to a first embodiment
- FIG. 2 illustrates, using a view according to FIG. 1 a, an embodiment of an adapter according to the invention according to a second variant
- Figures 3a and 3b illustrate in a view according to Figures 1 a and 2, a further embodiment of a designed according to the invention
- Connection element in the form of a sealing plug.
- FIGS. 1 a to 1 c illustrate, based on three views, a first variant of an inventive design of a connection element in the form of an adapter 1 for the assignment to an air coupling of an automatic train coupling.
- the designs of the air coupling elements for automatic train couplings essentially consist of an air tube with a sealing ring and concentrically arranged grippers, which get caught in the coupled state and ensure tightness in the event of negative and positive pressure Execution of an air coupling, for example in the form of a half-shell coupling, which does not fit on the coupling head of the automatic train coupling.
- the adapter 1 comprises means 2 for fastening and airtight coupling with an air coupling element, means 3 for coupling between the adapter 1 attached to the air coupling element and the other, differently designed air coupling element and means 4 for ensuring an airtight connection between the air coupling elements to be coupled together.
- the adapter 1 comprises a head element in the form of the adapter head 5 and an air guide tube 6.
- the means 2 for fastening and airtight coupling to the air coupling element are preferably provided in the area of the air tube 6.
- the air guide tube 6 comprises a first section 7 which can be inserted into the coupling head of the air coupling element.
- the outer diameter in the first partial region 7 of the air guide tube 6 is preferably selected such that it merely forms a clearance fit with the inner diameter of the coupling head of the air coupling element.
- the bearing base for the Adapter 1 determined in the coupling head of the air coupling of an automatic train coupling.
- a larger axial extension of the first partial region 7 of the air guide tube 6 is preferably selected in order to achieve the largest possible bearing base.
- a sealing device 8 is provided which interacts with the corresponding sealing ring on the coupling head of the air coupling in the installed position.
- the sealing device 8 is located on a stop surface facing away from the head element 5 14 of a flange-like element 9 is arranged, which adjoins the first section 7 in the direction of the adapter head 5 and closes the first section.
- the flange-like element 9 has an outer diameter which is larger than the outer diameter of the sealing ring on the coupling head of the air coupling.
- the sealing device 8 is preferably designed as a lip seal.
- the means 3 for coupling between the coupling elements, in particular the adapter 1 coupled to a first air coupling head of an air coupling of an automatic train coupling and the other coupling element in the form of a half-shell coupling, are formed by the adapter head 5.
- the contact surface 10 this has a complementary structure to the other second coupling element, in particular the coupling head of the other second coupling element to be coupled with it and not shown here - in particular one element a half-shell coupling.
- the means 4 for ensuring an airtight connection between the air coupling elements 4 to be coupled to one another are also carried by the adapter head 5.
- These include at least one sealing device 11, which is also complementary to the air coupling head to be coupled to the air coupling head connected to the adapter, and elements 1 ⁇ of a corresponding coupling mechanism for connection with a half-shell coupling element arranged on another wagon or an air coupling element provided with an adapter 1.
- the means 2 for fastening and airtight coupling of the adapter 1 to the coupling head of the air coupling comprise at least one locking element which is arranged on the flange-like element 9 or the air guide tube 6 and which is designed such that it is supported on the surfaces of the gripping elements in the manner of a barb, ie is complementary to partial areas of the gripping elements and engages behind them.
- a hook 13 and a lever in the form of a pawl device 12 are provided.
- the individual functional positions of the adapter 1 can be determined by means of the lever 13.
- FIG. 1b illustrates this in a side view of the adapter 1.
- the adapter 1 When the lever is unlocked, the adapter 1 is first brought into a position I, shown here by a broken line, at which air can escape. Only then can the hooking 13 be released. In connection with a blind half shell, i.e. the design of the adapter head as a blind half-shell, the adapter can also be used as a plug. Position II represents the position of the pawl device 12 in the hooked state, position III the position of the pawl device 12 in the unloaded - preloaded state.
- the pawl device is preferably spring-loaded, which must be released to open or remove the adapter 1.
- the inclined plane of the gripping elements on the air coupling head is used so that the adapter 1 cannot be released by hand as long as the air line is under pressure.
- FIG. 2 illustrates an embodiment of an adapter 1, 2 according to a variant 2, in which the adapter cannot be removed as long as there is overpressure in the air line.
- the adapter in conjunction with a blind half-shell as a sealing plug for the air coupling head of an air coupling of an automatic train coupling.
- the hook 13 is hooked under pressure to the coupling head of the air coupling, so that it is no longer possible to release it in the axial direction, but only when there is a relief.
- FIGS. 3a and 3b illustrate on the basis of a view according to FIGS. 1a and 2 different designs of the connecting element as sealing plugs 15.3a and 15.3b.
- the design of the head element 5.3a is analogous to that of the adapter, the head element 5.3a being closed, which can be done by designing the air duct as a blind duct, in this case the same basic shapes for the head element as in the adapter version can be used.
- FIG. 3b illustrates a particularly compact design of the head element as a connecting flange element of the air guide tube, the flange element 9.3b already closing the air guide channel in the air guide tube 6.3b.
- adapter. 2 means for fastening and airtight coupling of the adapter with a coupling head of an air coupling of an automatic train coupling
- connection element coupled to the air coupling element and another coupling element
