Definitions

• the present invention relates to a pipeline, in particular hydraulic line of a hydraulic system of a motor vehicle, comprising a first conduit part and a second conduit part, wherein the second conduit part is inserted in a connecting region in the first conduit part.
• Pipelines especially plastic hoses, even those same or different inner or outer diameter are usually connected by fittings as connecting means with each other, in which the fitting between the two pipes are arranged and this separates from each other so that the connecting means separates both line parts from each other, ie between both is arranged so that both line parts are not directly connected.
• a disadvantage of such compounds is that they have only a low pressure tightness.
• An object of the present invention is therefore to increase the pressure-tightness of pipelines comprising two interconnected piping parts.
• a pipeline in particular hydraulic line of a hydraulic system of a motor vehicle, comprising a first conduit part and a second conduit part, wherein the second conduit part is inserted in a connecting region in the first conduit part, wherein in the connection region a connecting means is arranged partially is disposed within the second line part and partially within the first line part.
• the connecting means in each case with parts in the opening, that is, the through the tubular casing of the respective pipe enclosed passage opening or - bore, is arranged.
• the line parts are made in particular of a flexible plastic.
• the connecting means preferably comprises a connecting piece which is partially inserted into the second conduit part.
• This in turn preferably comprises a sealing cone nipple for the frictional and / or positive connection with the second line. processing part.
• the outer diameter of the second conduit part is preferably widened in at least one subregion in which the sealing cone nipple is arranged, so that in the installed position an interference fit between the first and the second conduit part in the subregion is effected.
• the connecting means preferably has a head piece, which protrudes at a line end of the second line part of this, wherein the head piece has an increasing from an end face to the line end diameter.
• the head piece for this purpose is preferably spherical segment-shaped or alternatively, for example, frusto-conical. This shape allows easy centering during assembly.
• the largest outer diameter of the head piece is preferably larger than the outer diameter of the adjoining the head piece second line region.
• the above-mentioned problem is also solved by a method for connecting a first line part to a second line part, wherein the second line part is inserted in a connection area in the first line part, wherein first a connector is inserted into a line end of the second line part and then the second Conduction part is introduced with the connecting piece arranged thereon in a line end of the first line part.
• FIG. 1 shows a section through an embodiment of a pipe according to the invention.
• Figure 2 shows the second conduit part and the connecting means prior to assembly.
• Fig. 1 shows a section through an embodiment of a pipe according to the invention 1.
• the pipe 1 comprises a first pipe part 2 and a second pipe part 3, the are connected together in a connection region 4.
• the connection of the first line part 2 with the second line part 3 is done in such a way that a line end 6 of the second line part 3 is inserted into a line end 5 of the first line part 2.
• a connecting means 7 is arranged in the connecting region 4.
• Fig. 2 shows the second conduit part 3 and the connecting means 7 prior to assembly
• Fig. 3 shows the pre-assembled with the second conduit part 3 connecting means 7 prior to assembly with the first conduit part 2.
• the two line parts 2 and 3 are flexible Plastic hoses, wherein the outer diameter of the second conduit part 3 corresponds approximately to the inner diameter of the first conduit part 2. Ideally, the outer diameter of the second conduit part 3 and the inner diameter of the first conduit part 2 are chosen so that a transition fit or interference fit between them is produced.
• the connecting means 7 is provided.
• This comprises a connecting piece 8 and a head piece 9.
• the connecting piece 8 is inserted in the installed position in the second conduit part 3, the head piece 9 protrudes in the installed position from the conduit end 6 of the second conduit part 3, as can be seen from Fig. 3.
• the connecting piece 8 has a Dichtkegelnippel 10 for producing a frictional and / or positive connection with the second conduit part.
• the Dichtkegelnippel 10 includes for this purpose one or more frustoconical regions 11, the largest outer diameter DAmax is greater than the inner diameter DI3 of the second conduit part 3 and their smallest outer diameter DAmin is smaller than the largest outer diameter DAmax and equal to or slightly larger than the inner diameter DI3 of the second conduit part 3 is.
• An insertion cone 12, facing away from the head piece 9, of the connecting means 7 is configured as a truncated cone and has a smallest outer diameter DA12min which is smaller than the inner diameter DI3 of the second conduit part 3 and serves as an insertion and assembly aid.
• the head piece 9 is formed in the present embodiment spherical segment-shaped and may alternatively be formed, for example, frusto-conical or the like.
• the outside diameter changes from a minimum diameter D9min on an end face 13 to a maximum diameter D9max.
• the minimum diameter D9min is smaller than the inner diameter of the first line part 2 and serves as an assembly aid for introducing the second line - A - part 3 and the connecting means 7 pre-assembled module.
• the maximum diameter D9max of the head piece 9 is chosen so that it is pushed onto the connecting piece 8 in the second conduit part 3 is greater than the outer diameter of the second conduit part 3 in the region of the conduit end 6, which abuts in the installation position on the head piece 9.
• FIG. 2 and 3 illustrate the assembly of the pipeline 1.
• the connecting means 7 is inserted into the second conduit part 3, one obtains the intermediate shown in Fig. 3 on the left, in which the conduit part 3 at one end of the line 6, the connecting means 7.
• this preassembled intermediate module is inserted into the line end 5 of the first line part 2, the finished assembled connection of the two line parts and thus the fully assembled pipe is shown as a detail in Fig. 2.
