Definitions
- the invention relates to a coupling head for the pneumatic connection of the brake systems of a towing vehicle and a trailer, wherein the coupling head has a housing with at least one connection for a flexible compressed air line which at least partially tolerates at least in the region of the terminal by at least one flexible, movements of the compressed air line Reinforcing sleeve is reinforced, according to the preamble of claim 1.
- a generic coupling head is known for example from CH 530 290, wherein the housing is made of metal and is for example an aluminum die-cast part. At least one end of such a compressed air line is usually enclosed by a reinforcing sleeve, wherein the reinforcing sleeve is preassembled on the compressed air line.
- the reinforcing sleeve serves to relieve this at a bending stress of the compressed air line or to avoid kinking of the compressed air line.
- the compressed air line is then fastened with its end enclosed by the reinforcing sleeve end in the connection to the housing by means of a so-called. Fittings, ie that the end of the compressed air line is pushed with a fitting into the connection hole and this position is then secured by an external union nut.
- the present invention has for its object to develop a coupling head of the type mentioned in such a way that it is easier and less expensive to manufacture.
- the invention is based on the idea that at least one of the at least one port exhibiting part of the housing of the coupling head formed together with the reinforcing sleeve as a one-piece injection molded plastic and a free end of the compressed air line through the reinforcing sleeve and into a connection bore of the terminal projecting into the Injection molding is bonded cohesively.
- the inventive method for producing the coupling head provides that a free end of the compressed air line is positioned in an injection mold for injection molding of the at least one of the reinforcing sleeve and the at least one terminal having part of the housing injection molding of injection-moldable plastic at a location at which the at least one connection is provided and that then the end of the compressed air line is injection molded during injection molding of the injection molding of the plastic to form a material connection between the injection molding and the compressed air line.
- the housing or at least the part of the housing containing the at least one connection, the reinforcing sleeve and the compressed air line as a structural unit are manufactured or connected to one another in a single injection molding operation. This procedure saves a manual assembly of components and the provision of fittings, which is why the coupling head according to the invention is inexpensive to manufacture.
- the measures listed in the dependent claims advantageous refinements and improvements of the invention are possible in claim 1.
- At least the part of the housing having the at least one connection together with the reinforcing sleeve is a one-piece injection molding of polyamide.
- At least the free end of the compressed air line is preferably preheated prior to positioning in the injection molding tool.
- Fig. 1 is a front view of a coupling head according to a preferred embodiment
- Fig. 2 is a side view of the coupling head of Fig. 1;
- Fig. 3 is a cross-sectional view of the coupling head of Fig. 1 taken along the line III-III;
- the embodiment of a coupling head for pneumatic connection of the brake systems of a towing vehicle and of a trailer, designated as a whole by 1 in FIG. 1, has a housing 2 on which a claw, not of interest here, is known from DE 199 31 162 A1, for example and a guide rail are formed. With the help of the claw and the guide rail of the coupling head 1 can be coupled with another coupling head.
- a shut-off member is generally provided in one of the coupling heads, in general, this is the coupling head on towing vehicle.
- the coupling head 1 given in FIG. 1 is provided, for example, for a trailer.
- the coupling head 1 has a connection 4 as an energy supply and another connection 6 as an energy outflow.
- compressed air from the counter-coupling head not shown, is directed into the one port 4 and leaves the coupling head 1 through the other port 6 as an energy drain.
- the direction of flow of the compressed air is also reversible, such that the compressed air leaves the other connection 6 after passing the coupling head 1, the one connection 4 as an energy effluent and is guided into the counter-coupling head.
- the illustrated embodiment provides a coupling head 1 preferably used for trailers, in which compressed air from the towing vehicle passes through the one terminal 4 as energy flow into the coupling head 1 and leaves it through the other terminal 6 as an energy drain.
- coupling heads 1 of the type in question are used to connect supply lines and brake lines, called compressed air on the one hand supply compressed air and on the other hand brake line compressed air.
- the two ports 4, 6 of the coupling head 1 are formed in a housing 2, wherein the other terminal 6 is provided for a flexible compressed air line 10, which at least in the region of the coupling head 1 by a flexible, movements of the compressed air line 10 at least partially tolerating reinforcing sleeve 12 amplified is.
- the reinforcing sleeve 12 the reinforcing sleeve formed in its outer wall slots, which each seen in the circumferential direction extend only over a pitch circle and are separated by webs from each other, as can be seen in particular from Figure 2.
- the housing 2 in the context of the invention comprises all components which have conventional housing of coupling heads, such as the aforementioned claw and guide bar.
- the entire housing 2 of the coupling head 1 is formed together with the reinforcing sleeve 12 as a one-piece injection molded article 14 made of plastic, wherein a free end 16 of the compressed air line 10 through the opening of the reinforcing sleeve 12 axially therethrough and into a connection bore 12 of the other terminal 6 projecting is materially connected to the injection molding 14.
- the end 16 of the compressed air line 10 at least in the region of the connection bore 12 with the injection molded article 14, in particular with the housing 14 integrally connected.
- the compressed air line 10 may additionally but also be connected over at least a portion of the length of the reinforcing sleeve 12 with this by the injection molding process, especially if the reinforcing sleeve 12 is relatively stiff and allows very little movement.
- the compressed air line 10 is preferably also made of polyamide.
- the other end of the compressed air line is preferably provided with a conventional fitting and initially described.
- the free end 16 of the compressed air line 10 in a not easily shown but easily imaginable injection molding tool for injection molding of the reinforcing sleeve 12 and the housing 2 together with mounting eye 20 existing Spntzgussformlings 1 4 of preferably polyamide positioned at a location at which the other terminal 6 is provided.
- the end 16 of the compressed air line 10 is then encapsulated by the plastic to form a material connection between the injection molding 14 and the compressed air line 10.
- the free end 16 of the compressed air line 10 is preheated or preheated prior to positioning in the injection mold.
- the free end 16 of the compressed air line 10 can also be preheated or preheated in the positioned injection position in the injection molding tool prior to encapsulation.
- a mounting eye 20 for attaching the coupling head 1 on the frame of the trailer is preferably part of the housing 2 and thus also of the one-piece injection molded article 14 and is manufactured together with this.
- the result of the process is therefore an insoluble assembly consisting of the housing 2 and the reinforcing sleeve 12 as injection molded article 14 on the one hand and the compressed air line 10 on the other hand, which is preferably at least partially spirally formed.
- the other free end of the compressed air line for connection to other terminals or lines of the pneumatic brake system is preferably provided with a detachable fitting.
