Description

The The invention relates to a conduit for the transportation or harboring of a Fluids according to the preamble of claim 1. The invention relates Furthermore, a method for producing a line according to the preamble of claim 7 and a clamping body for attachment to a line according to claim 8th.

Around an exact location or alignment of lines in vehicles too guarantee, it is usually necessary to mark the lines in the places at which the lines by a holder arranged in the vehicle run or to which they are fastened. This is especially true at Plastic lines required because these lines are a material-related flexibility can have the exact installation in the vehicle, purely on the actual contour, almost impossible.

Out For this reason, in the prior art position markings used, which interact with the holders in the vehicle, and the ensure should that be a targeted assignment or attachment of the line in the area of the holder allows becomes. The markers can be realized in different ways. For example, the Marking by a printing process, a tape or a local Material deformation are created. A disadvantage of the printing process and the tape process is the actual implementation of this situation in the assembly process, since the exact position alignment depends on the holder the care of the installer when installing the position marker and the careful Alignment of the marking to a holder in the vehicle assembly.

Under a local one Material deformation is a process to be understood in which lines (Pipes) in the appropriate places, for example, left and / or right of the holder, by swaging the line with the corresponding Be provided beads.

hereby the position in or on the holder is clearly recognizable and fixes itself for example, by a positive connection between the holder and the bead.

adversely However, in the known from the prior art lines is, that the upsetting of the beads and also a possible printing process very time-consuming and thus expensive.

The The object of the invention is thus to provide a remedy for the previously to suggest the problem described.

These The object is achieved by a Line according to the preamble of claim 1, a method for Production of a conduit according to the preamble of claim 7 and a clamp body for attachment to a line according to claim 8 solved.

Further advantageous features include the subclaims.

there is first the marked line for carriage or harboring a fluid in a vehicle characterized that the marking element is designed as a clamping body, wherein the clamp body surrounds the line section at least partially. Instead of the elaborate attachment of beads or compressions can the Clamping body thus be attached to the appropriate point on the line.

Prefers, but not mandatory, the clamping body may be formed as a clip, wherein the clip preferably has a shape complementary to the line section cross-section having. In general, therefore, the cross section of the clip or of the clamping body one of the line corresponding circular cross-section.

For example forms the clamp body slight resilient leg portions (which in turn preferably substantially complementary to the form Line section are formed), wherein the clamping body by the spring force of the leg sections on the respective line section is held. The clamp body can therefore be clipped under light pressure on the corresponding line section become. Further fixatives are therefore not necessary.

For example can the clamp body Made of plastic and preferably in plastic injection molding be prepared. This results in many cases a plastic (line) -to-plastic (clamp body) connection.

Becomes heated the line in the corresponding manufacturing process, connects the clamp body through the heat input cohesively with the line and is thus fixed.

Of the clamping bodies can have at least one recess or the like, the manufacturing technology is conditional or serve the weight and / or material savings should.

For example, an adhesive, in particular adhesive, plastic or the like, may be provided in the contact region between the clamping body and / or line or line section. It has It has been shown that Santoprene plastic is currently the most suitable.

• – Bereitstellen eines Werkzeuges mit einer Kontur, wobei die Kontur im Wesentlichen der Kontur der Leitung entspricht, und wobei die Kontur zumindest eine Ausnehmung zum Anbringen eines Klemmkörpers aufweist;
• – Einlegen der noch geraden aber teilflexiblen Leitung in das Werkzeug;
• – Anbringen des zumindest einen bevorzugt mit einem Haftmittel beschichteten Klemmkörpers an der im Werkzeug befindlichen Leitung im Bereich der Ausnehmung;
• – Erwärmung des Werkzeuges unter gleichzeitiger Formgebung der Leitung und Verklebung des Klemmkörpers an der Leitung;
• – Entnahme des Fertigteils.

The invention further relates to a method for producing a corresponding line, wherein the method comprises at least the following method steps:

• - Providing a tool with a contour, wherein the contour substantially corresponds to the contour of the line, and wherein the contour has at least one recess for attaching a clamping body;
• - Inserting the still straight but partially flexible cable into the tool;
• - Attaching the at least one preferably coated with an adhesive clamp body on the line located in the tool in the region of the recess;
• - Heating the tool while shaping the line and bonding of the clamp body to the line;
• - Removal of the finished part.

The Material choice of the clamp body and the line is preferably to be chosen such that the merger takes place at the temperatures prevailing in the oven process. It can but also, as already mentioned, a suitable (melting) adhesive or plastic are attached, the in the warming process the connection between clamping body and wire guaranteed.

The Selection of materials (for Cable and clamp body) considered, that the created connection arrangement between clamping body and Line, under the eventual influence of temperature during operation flowing in the pipe Fluids (eg hot oil or water) does not solve again.

The The invention further relates to a clamping body for attachment to a Management.

Next gives the process engineering improvements described above There is also a qualitative improvement due to the fact that that the attachment of the position marking takes place only in the tool and not in an upstream process on the straight workpiece (line). This results in a much lower tolerance and therefore a much more exact position of the lines in the vehicle.
