Description

The invention relates to a line device for a motor vehicle, having a clamping element which has an element opening, with a housing element which has a receiving opening for guiding a fluid and with a line element which is inserted in a mounting position on the one hand in the element opening and on the other hand in the receiving opening and is clamped by means of the clamping element relative to the housing element.

Such conduit devices can be used, for example, for guiding gases, liquids or other media.

From the DE 43 41 034 A1 is a hydraulic line connection for connecting a plurality of hydraulic lines known. A rigid tubular connecting element of the hydraulic line connection is formed in a cylindrical shape at one end at its radial circumference and held axially movable on one of the hydraulic lines. At an opposite end, the connecting element is spherically formed on its circumference and connected to the other hydraulic line. Due to the spherical shape, a tolerance compensation can be made possible.

The DE 10 2005 023 583 A1 describes a plug-in coupling for connecting two fluid lines. The plug-in coupling comprises a coupling socket and a tubular coupling component, in which the coupling socket is inserted fluid-tight. The coupling socket comprises a circumferential retaining rib which merges into a cylindrical section tapering towards one end of the coupling neck.

Object of the present invention is to provide a line device of the type mentioned, by which an improved tolerance compensation is possible.

This object is achieved by a conduit device having the features of patent claim 1. Advantageous developments of the present invention are the subject of the dependent claims.

The invention relates to a line device for a motor vehicle, having a clamping element, which has an element opening, with a housing element, which has a receiving opening for guiding a fluid and with a line element which is inserted in a mounting position on the one hand in the element opening and on the other hand in the receiving opening is and is clamped by means of the clamping element relative to the housing element, from.

In order to provide a conduit device with improved tolerance compensation, it is provided according to the invention that the conduit element has at least one bulge region on which the conduit element is supported in the mounting position on the housing element and has a cone region adjoining the bulge region and introduced into the mounting opening in the mounting position , This is advantageous because the conical region allows at least a slight tilting of the conduit element in its mounting position relative to the housing element and thereby provides improved tolerance compensation insofar as the cone region simultaneously prevents excessive tilting movement of the conduit element relative to the housing element.

While in systems known from the prior art, in which, for example, only one ball element is provided at line ends, although a tolerance compensation is also possible, but in a tilting large leverage can occur, which can lead to leaks, in contrast, by the cone region an effective support of the conduit element with respect to the housing element can be realized on the conduit element. In other words, a maximum tilting of the conduit element is simultaneously limited and defined by the present, for example, very short cone area by the present conduit device.

In an advantageous embodiment, the cone region has a cone wall element that tapers away from the arching region in the axial extension direction of the conduit element and radially inwardly in the radial direction of extension of the conduit element at an acute angle. This is advantageous since, due to the acute angle, a line element opening of the line element which can be flowed through by the fluid can have a particularly large diameter, as a result of which particularly small flow losses occur when flowing through the line element or when the fluid flows into the line element via the line element opening.

In a further advantageous embodiment, at least one sealing element is provided on the conical region, which is clamped in the mounting position between the conduit element and an inner surface of the housing element which peripherally delimits the receiving opening. This is advantageous since the sealing element arranged on the conical region is also loaded in a very few load directions in the event of any relative tilting of the conduit element relative to the housing element in the assembly position. Unlike an arrangement of the sealing element, for example on the Curvature region, the sealing element is thus hardly burdened by friction, even with a possible relative tilting between the conduit member and the housing member, whereby increased wear of the sealing member due to the tilting can be at least largely prevented.

In a further advantageous embodiment, the curvature region is at least partially curved spherically. This is advantageous since such a spherically curved bulge area is particularly inexpensive and easy to manufacture.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

1 shows a sectional view of a line device 10 for a motor vehicle. The pipe device 10 has a clamping element 12 with an element opening 14 on. Furthermore, the conduit device 10 a housing element 16 with a receiving opening 18 for guiding a fluid and a conduit element 20 which is in an in 1 shown mounting position 50 on the one hand in the element opening 14 and on the other hand in the receiving opening 18 is introduced on. In the mounting position 50 is the conduit element 20 by means of the clamping element 12 braced against the housing member 16 and thereby on an inner surface 17 of the housing element 16 in Appendix.

As in particular from the synopsis of 1 With 3 can be seen, the conduit element has 20 at least one and at least partially spherical arched area 30 on, on which the conduit element 20 in the mounting position 50 on the housing element 16 or on the inner surface 17 of the housing element 16 is supported.

In addition, the line element 20 one, to the vault area 30 subsequent and in the mounting position 50 in the receiving opening 18 introduced cone area 40 on. At the cone area 40 a circumferential groove is provided, in which a sealing element 22 is arranged. The sealing element 22 is designed as an O-ring.

The clamping element 12 is by means of a in the housing element 16 bolted screw 24 fixed by tightening the screw 24 also a distortion of the conduit element 20 at the vault area 30 on the one hand with respect to the clamping element 12 and on the other hand with respect to the housing element 16 can be done.

As in particular from 1 indicates the cone area 14 in, in the axial extension direction 70 of the conduit element 20 from the bulge area 30 away and in the radial direction of extension 72 of the conduit element 20 at an acute angle α radially inwardly tapering cone wall element 42 on. This acute angle α can correspond, for example, to a value of 1 °.

The sealing element 22 is like 1 shows, in the mounting position 50 between the conduit element 20 and the, the receiving opening 18 peripherally delimiting inner surface 17 of the housing element 16 trapped.

2 and 4 show the conduit device 10 during assembly, taking particular 4 shows that the conduit element 20 opposite the housing element 16 around a tilt angle β can be tilted to any tolerances, which, for example, in the manufacture of individual components of the conduit device 10 and additionally or alternatively during assembly of the conduit device 10 can come to compensate.

The bulge area 30 Generally speaking, this can also be the sphere of the pipe element 20 be designated. The clamping element 12 can be configured for example as a pressure plate and in the mounting position 50 at one to the sphere (vault area 30 ) correspondingly curved and conical or spherical contact surface of the clamping element 12 with the bulge area 30 in Be plant. The inner surface 17 of the housing element 16 can also go to the bulge area 30 correspondingly conical or spherical. The receiving opening 18 of the housing element 16 can also be referred to as a housing bore and be configured cylindrical.

The bulge area 30 (the sphere of the pipe element 20 ) can with the cone area 40 , which may also be referred to as a chronic connection or as a socket, be soldered or with the cone area 40 be rolled. The bulge area 30 can also be annular and formed on the conduit element 20 be pressed on. In other words, the bulge area 30 also provided in the form of a ring and on the conduit element 20 be pressed on. This can in particular before a cold deformation of the conduit element 20 made during its production, wherein still no contact with the fluid occurs.

The bulge area 30 , which also as a ball between the pressure plate (clamping element 12 ) and the housing element 16 may be formed during assembly of the conduit element 20 represent a ball joint. The angle α allows a compensation of tolerances, which, for example, in the manufacture of the line device 10 or during assembly of the conduit element 20 can come. When tightening the screw 24 is the ball joint or the conduit element 20 fixed. A maximum tilting of the pipe element 20 is due to the very short cone area 40 Are defined. At this cone area 40 is also the sealing element 22 added. In a design of the conduit device 10 Make sure that the sealing element 22 as close as possible to the camber area 30 is arranged to give an eccentricity between the sealing element 22 and the receiving opening 18 to minimize. The sealing element 22 can be designed or chosen so that at a corresponding maximum eccentricity (or maximum angular compensation) is still guaranteed a secure seal. The bulge area 30 , ie the spherical part of the pipe element 20 can be soldered, for example, within a prefabricated terminal. Alternatively, the spherical portion (bulge area 30 ) as well as the nozzle (cone area 40 ) directly on the conduit element 20 be rolled or as a ring on the conduit element 20 be plugged before the line element 20 For example, a cold deformation is subjected. In this case, the bulge area has 30 or the ring is not in contact with the fluid. Through the conduit device 10 For example, a connection can be provided which, for example, in the case of a sealing element designed as an O-ring 22 and corresponding design already tilt angle β ranging from minus 1 ° to plus 1 °. This corresponds to a position tolerance compensation of 7 mm diameter at another end of the line element in connection with other compensation elements, for example, in a 20 cm long line 20 ,

In summary, the line device allows 10 the use of rigid solid metal pipes in areas where previously only more flexible materials or complex and costly solutions could be used. Through the conduit device 10 In particular, compounds with soft, flexible lines, for example made of plastic or composite materials, which compensate for any tolerances by elastic and additionally or alternatively plastic deformation substitute. This can be disadvantages in terms of pressure transfer behavior, flame resistance, cost and pressure resistance can be avoided. Furthermore, a problem can be solved by the line device 10, according to which lines of solid metal due to their rigidity in the application or tolerance compensation can be used only limited. Furthermore, through the conduit device 10 also be dispensed with a use of sealed by an elastomeric ball joints, which disadvantages in terms of manufacturing, complexity and cost can be avoided.

The pipe device 10 allows a total tight fastening of rigid, media-carrying lines, such as the line element 20 with slight angle compensation and tolerance compensation.
