- a press or transition fit can be provided, as can the first stage 8 with the outer diameter D a i of the first line part 2 form a press or transition fit.
- a press or transition fit and a suitable clearance fit can be used and friction generated, for example by an imbalance in the relative rotation or the like to melt the surfaces.
- aggregate material or a suitable roughened surface could also ensure that in the case of a tivcardung of the first line part relative to the second line part 3 sufficient heat for welding both parts together.
- a friction-welded connection is produced between the first conduit part 2 and the second conduit part 3 in the region of the connection region 5.
- connection sleeve 25 shows an exemplary embodiment of a connection according to the invention of two pipe parts, here a metal pipe 23 with a plastic pipe 24, by means of a connecting sleeve 25.
- the plastic pipe 24 corresponds to the first pipe part as shown in FIGS. 1-3
- the connecting sleeve 25 corresponds to the second pipe part FIGS. 1-3.
- the connection between plastic pipe 24 and coupling sleeve 25 is effected by friction welding as previously described. On the connection between the plastic pipe 24 and coupling sleeve 25 is therefore not discussed in more detail, since this corresponds to the connection shown above.
- the connection sleeve 25 has a first connection region 5.1 for connection to the plastic tube 24 and a second connection region 5.2 for connection to the metal tube 23.
- the second connection region 5.2 comprises a Christmas tree connection or the like, in which a sealing latching connection between the connection sleeve 25 and the metal tube 23 can be produced by inserting the metal tube 23 into the connection region 5.2.
- the metal tube 23 comprises one or more, in the present embodiment, two, in cross-section substantially trapezoidal rings 26 which engage in correspondingly shaped annular groove 27 of the connecting sleeve 25 and thereby produce a positive connection.
- the rings 26 and the annular groove 27 at the same time contribute to the sealing effect between metal pipe 23 and coupling sleeve 25 at.
- An end face 28 forms, together with a stop 29, a further sealing element.
- a knurl 30 engages in an annular groove 31 and serves to prevent rotation of the metal tube 23 relative to the connecting sleeve 25.
- a RMFeis 30 may be provided here, for example, a four- or polygonal profile, which engages in the annular groove 31.
- the connecting sleeve 25 at both connecting portions 5.1, 5.2 each have an insertion nose 32.
- the coupling sleeve 25 is preferably made of the same material as the plastic tube 24. This facilitates a connection by friction welding.
- the connecting sleeve 25 may be made of a composite material containing about 15-50% glass fiber content or the like.
- the plastic tube 24 and the connecting sleeve 25 or the first line part 2 and the second line part 3 may be made, for example, of a plastic PA12 or of a plastic PA612.
- the plastic tube 24 and the metal tube 23 may have different outer and inner diameter, the plastic tube 24 may for example have an inner diameter of 6.3 mm, 4.7 mm or 3.5 mm (conventional brake hose).
- the plastic tube 24 is in one embodiment, a 5x1 plastic tube.
- the coupling sleeve 25 is preferably manufactured by injection molding. As a result, it is possible to give the connecting sleeve 25 an almost arbitrary shape, in particular a shape which deviates from the rotational symmetry.
- the connection sleeve 25 may therefore have additional tasks in addition to the pure connection of the metal tube 23 with the plastic tube 24.
- 5 shows an exemplary embodiment of a connecting sleeve 25, which has a right angle between the axis of rotation of the metal tube 23 and the plastic tube 24. Instead of a right angle here also any other angle can be provided. This saves an additional bending operation either in the metal tube 23 or the plastic tube 24.
- FIG. 6 shows another embodiment of a coupling sleeve 25 according to the invention, in which a tab 33 is integrally formed with a bore 34.
- the connecting sleeve 25 for example, screwed or riveted to the body, so that an additional fastener can be saved.
- Fig. 7 shows a further embodiment of a connecting sleeve 25 according to the invention, in which an additional hydraulic element 35 is integrated.
- the additional hydraulic element 35 is a so-called peak torque limiter (PTL), which is a flow direction-dependent throttle, which develops no or only slight throttling effect in one flow direction and has a high throttling effect in the other direction.
- PTL peak torque limiter
- the hydraulic element 35 may include a tingling filter and / or a damper box or the like.
- the plastic housing of the connecting sleeve 25 may have a coloring (natural, black, blue and the like) for easier differentiation of different constructions (ie, for example with PTL, without PTL, dimensioning of the PTL and the like).
- housing 36 wherein the arrangement and shape of the housing 36 encode the construction variants.
- the coupling sleeve 25 can record on its outer surface a part number, for example, for the entire assembly (metal tube 23, plastic tube 24, coupling sleeve 25) and can be labeled inexpensively, for example, with a laser device, hot stamping or the like.
- the coupling sleeve 25 can also be designed in two parts.
- the plastic pipe 24 may be designed in two-part design, eg with an additional slipped over temperature protection (heat shield).
