Description

The invention relates to a connection arrangement of a first line element to a second line element, in particular for a motor vehicle, according to the preamble of claim 1.

Such a connection arrangement of a first line element to a second line element, in particular for a motor vehicle, is for example the WO 03/048624 A1 to be known as known. In this connection arrangement, the line elements are fluidly connected to one another by means of at least one band clamp which at least partially surrounds the outer circumference of the line elements. The band clamp is used for mutual fixation of the line elements. As a result of their fluidic connection, for example, a medium flowing through the first line element can flow over from the first line element into the second line element.

In the WO 03/048624 A1 For example, a positioning disc is used to position the band clamp relative to the conduit members in the circumferential direction thereof. In other words, the positioning disk is used to position and hold the band clamp relative to the line elements in a predeterminable position. For this purpose, the positioning disc acts in a form-fitting manner with at least one of the line elements and in a form-fitting manner with the band clamp. For this purpose, a processing of the at least one line element is required. In addition, the positioning disk surrounds the line elements at least partially on the outer circumference side. The Positionierscheibe thus represents a large, additional component. This leads to a high cost and a high space requirement and high cost of the connection assembly.

It is therefore an object of the present invention, a connection arrangement of the type mentioned in such a way that the cost and space requirements of the connection arrangement can be kept particularly low.

This object is achieved in the respective connection arrangement with the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are entered in the remaining claims.

In order to further develop a connection arrangement specified in the preamble of claim 1 type such that the space requirements and the cost of the connection arrangement can be kept particularly low, according to the invention at least one extending in the axial direction of the band clamp and provided with the line elements and the band clip form-fitting cooperating positioning element , By means of which the line elements and the band clamp are positioned in the circumferential direction of the band clamp relative to each other.

In other words, both the line elements and the band clamp in the circumferential direction of the band clip and thus the line elements are moved relative to each other in a predetermined mounting position, wherein the positioning element cooperates in this mounting position form-fitting manner with the line elements and the band clip. Thus, the conduit member and the band clamp are aligned by means of the positioning element relative to each other and held in this mounting position. In this case, the form-fittingly cooperating with the line elements and the band clamp positioning element limits a relative movement between the line elements and the band clamp in the circumferential direction of this. In particular, it can be provided that such a relative movement or relative rotation between the first line element and the second line element and between the line elements and the band clamp is avoided by means of the positioning element.

The positioning element extending in the axial direction does not have to surround the line elements on the outer peripheral side and can thus be configured even with particularly small external dimensions. Thus, the weight and space requirements of the connection arrangement can be kept particularly low. In addition, a complex processing of the line elements, as would be required for example when using a positioning, can be avoided. In addition, the positioning element itself can be produced particularly inexpensively, so that the cost invention arrangement can be kept low.

The positioning element is for example formed on the outer peripheral side in the form of a straight circular cylinder. The positioning element may preferably be a pin, for example a dowel pin and / or a dowel pin. The pin is at least partially received, for example, in respective, corresponding receptacles of the line elements and the band clamp. If the pin is designed as a tensioning pin, the pin is braced with at least one of the conduit elements and / or with the band clamp, whereby the tensioning pin is fixed to the at least one conduit element and / or the band clamp, in particular in the axial direction of the pin. This allows unwanted relative movements between the dowel pin and in line elements and the Band clamps in the axial direction of this can be avoided.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The above features and feature combinations mentioned 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 are no longer usable in respectively indicated positions, but also in other combinations or alone, without the frame to leave the invention.

The drawing shows in:

1 a schematic perspective view of two line elements which are arranged in the context of a connection arrangement to one another and connectable to each other by means of a band clamp;

2 a schematic perspective view of the band clip and a positioning disc, by means of which the band clamp in the circumferential direction of the band clamp and the line elements is positionable relative to the line elements;

5 a schematic perspective view of the connection arrangement according to FIG 4 with the band clamp.

2 and 3 serve to explain the background of the invention.

1 shows in a schematic perspective view of a connection arrangement 10 a first conduit element in the form of a flange 12 a turbine housing to a second conduit element in the form of a flange 14 an exhaust manifold of an internal combustion engine. The turbine housing is a first guide element for guiding exhaust gas of the internal combustion engine. The internal combustion engine is designed, for example, as a reciprocating internal combustion engine and serves to drive a motor vehicle. The internal combustion engine has an exhaust tract through which its exhaust gas can flow, in which the exhaust manifold and the turbine housing are arranged. Both the exhaust manifold and the turbine housing are exhaust gas flow elements through which exhaust gas can flow and which are used to guide the exhaust gas.

For example, the internal combustion engine has a plurality of combustion chambers in which exhaust gas is produced during a fired operation. The exhaust manifold serves to collect the exhaust gas from the combustion chambers. The turbine housing is part of a turbine of an exhaust gas turbocharger, wherein the turbine is driven by the exhaust gas.

The exhaust manifold and the turbine housing are above their respective flanges 12 . 14 fluidly interconnected so that the exhaust gas flowing through the exhaust manifold from the exhaust manifold can flow into the turbine housing. The exhaust gas flows through the flanges 12 . 14 so that also the flanges 12 . 14 From the exhaust gas flowable line elements or exhaust gas guide elements are.

In the context of the connection arrangement 10 are the flanges 12 . 14 by means of an in 1 not shown band clamp fluidly connected or connectable. The band clip is designed, for example, as a profile clip, in particular as a V band clip, and has a receptacle. The receptacle of the V band clamp is, for example, at least substantially V-shaped. In the finished state of the connection arrangement 10 The band clamp surrounds the flanges 12 . 14 outside circumference at least partially. This means that the band clamp outside circumference and in the circumferential direction of the flanges 12 . 14 at least partially, in particular at least predominantly, around the flanges 12 . 14 extends around. Here are the flanges 12 . 14 For example, at least partially included in the particular formed as a profile clip band clamp.

By means of the band clamp are the flanges 12 . 14 clamped together, especially pressed. In other words, the flanges become 12 . 14 held together by means of the band clip.

The band clip is for example off 2 recognizable and there with 16 designated. The band clamp 16 has two opposite, free ends 18 on, which by means of a clamping device 20 can be moved towards each other. Be the free ends 18 moved toward each other, so is a reduction of an inner circumference or an inner diameter of the band clamp 16 associated. As a result of this reduction of the inner circumference, the line elements (flanges 12 . 14 ) is subjected to a holding force and thereby fixed to each other. Out 2 and 3 is a positioning disc 22 recognizable. By means of the positioning disc 22 can the band clamp 16 in the circumferential direction of the band clamp 16 relative to the flanges 12 . 14 be positioned and held in at least one predetermined position. Furthermore, the positioning disk is used 22 to the band clamp 16 in its axial direction on the flanges 12 . 14 to fix. The axial direction of the band clamp 16 coincides with the respective axial direction of the flanges 12 . 14 together, whereby the circumferential direction of the band clamp 16 with the circumferential direction of the respective flanges 12 . 14 falls together.

To realize this positioning, the positioning disk acts 22 via respective tabs 24 positive and / or non-positive with the band clamp 16 together.

In addition, the positioning disc can be over the tabs 24 positively with at least one of the flanges 12 . 14 interact. Out 3 it can be seen that the positioning disc 22 for example with the flange 14 over the tabs 24 interacts positively.

In addition, the positioning disk points 22 very good 3 recognizable tabs 26 on, over which the positioning disc 22 in the circumferential direction of the flange 14 positively with these acts together. For this purpose, the flange 14 Outer peripheral side recesses in the form of pockets 28 on, in which the respective tabs 26 intervention. This allows the positioning disc 22 in the circumferential direction of the flange 14 be aligned relative to this and held in at least one predetermined position. Because of the positioning disc 22 also positive and / or non-positive with the band clamp 16 cooperates, thus also the band clamp 16 in the circumferential direction of the flange 14 be positioned relative to this.

Based on 2 and 3 it can be seen that the positioning disc 22 has large outer dimensions. In addition, complex and particularly costly, outer peripheral side machining of the flange 14 and / or the flange 12 required, for example, the bags 28 form and thereby the positive interaction of the positioning 22 with at least one of the flanges 12 . 14 to enable.

In contrast, a particularly simple, cost-effective and space-saving positioning of the band clamp 16 relative to the flanges 12 . 14 to realize is - how out 5 is recognizable - in the connection arrangement 10 at least one in the axial direction of the band clamp 16 and thus the flanges 12 . 14 extending positioning element in the form of a pin 30 intended. The pencil 30 each is partially in respective, corresponding receptacles of the flanges 12 . 14 and the band clip 16 recorded and thus acts with the flanges 12 . 14 and the band clip 16 form-fitting together. This causes the flanges 12 . 14 by means of the pen 30 positioned relative to each other in the circumferential direction and held in a predetermined position relative to each other. In addition, the band clamp is also 16 by means of the pen 30 in the circumferential direction of the band clamp 16 relative to the flanges 12 . 14 positioned and held in a predetermined position.

The pencil 30 is designed for example as a dowel pin and is in the axial direction in the respective receptacles of the flanges 12 . 14 and the band clip 16 plugged in.

This plugging in will make the pen 30 elastically deformed, in particular compressed. This is the pen 30 with the band clamp 16 and / or with at least one of the flanges 12 . 14 becomes strained and also in the axial direction relative to the flanges 12 . 14 and / or relative to the band clamp 16 established.

The pencil 30 is formed on the outer peripheral side in the form of a straight circular cylinder. Thus, the respective recordings of the flanges 12 . 14 and the band clip 16 on the inner circumference side be formed as a straight circular cylinder or hollow cylinder. For example, the recordings can be formed as respective holes. Thus, both the pen 30 as well as the respective pictures of the flanges 12 . 14 and the band clamp are made particularly simple, time and cost.

Preferably, it is provided that the pin 30 (Positioning element) as separate from the line elements (flanges 12 . 14 ) and separately from the band clamp 16 trained component is formed.

Overall, it can be seen that the pin 30 a double function. One is the pen 30 for positioning or alignment of the flanges 12 . 14 relative to each other in the circumferential direction thereof. In other words, the pen serves 30 for tangential positioning or alignment of the flanges 12 . 14 , The other is the pencil 30 also to the tangential Positioning or alignment of the band clamp 16 relative to the flanges 12 . 14 used in the circumferential direction. This allows the positioning disc 22 omitted. Alternatively it can be provided that the positioning 22 is used. Here, the positioning disc 22 used in particular for the above-mentioned axial fixation. But now the pen 30 used for tangential alignment, must be the tangential orientation of the band clamp 16 relative to the flanges 12 . 14 no more about the positioning disc 22 take place, since this only serves for axial fixation. Thus, at least the tabs 26 the positioning disc 22 and the bags 28 of the flange 14 omitted, so that both the positioning disc 22 as well as the flange 14 can be produced particularly inexpensively.
