Description

[0001] Agile connection

[0002] TECHNICAL FIELD

[0003] The invention relates to an agile connection device between two exhaust components e. g. interfaces for air intake or turbo charger housing or exhaust systems for an internal combustion engine or hybrid engine. Each of the two exhaust components has a support or a pipe socket or a duct to guide exhaust gas or air or any other fluid. The two components are interconnected to each other by connecting the two pipe sockets. Especially the invention relates to a movable and tight connection for fluids to compensate construction-related deviations between the two components, comprising a first pipe socket and a second pipe socket, each having an end section and a coaxial centre axis. The two pipe sockets are for assembly inserted with the end sections into one another in one of the two opposite axial directions and the two pipe sockets are connected to each other in axial direction in a form-fitting manner by a connecting device. The two connected pipe sockets are moveable relative to each other between an axial position_P1 and an axial position_P2, wherein the two axial positions are spaced by a distance_D of at least 1 mm. A sealing element is provided in the radial direction between the two moveable pipe sockets to seal the two pipe sockets together. The form-fitting connecting is realized in the first axial direction at a first axial end position and in the opposite (second) axial direction at a second axial end position.

[0004] BACKGROUND

[0005] An usual concept for a non-agile fluid tight connection between a manifold interface and an exhaust pipe socket interface is shown in US 4,289,169 B1. This connection is a fixed connection with a gasket and a metallic clip. This connection allows to compensate few displacements between the manifold interface and the exhaust pipe socket only in radial and circumferential direction by a small variation in view of the gasket. Such fixed connections cannot compensate dimensional deviations in the main axis of the flow cross-section. Any movement in axial direction would lead to leakage. According to DE 10 2008 018 137 A1 , a connection of two pipes is known which, when connected and sealed, allows both connected pipes to move in the axial direction. To connect the pipes, they have to be rotated relative to each other around the pipe axis. At the same time the connection described also allows the two pipes to tilt with respect to the angular position of the two pipe axes.

[0006] An existing concept for air intake systems to compensate construction-related deviations in axial direction is to use a soft pipe socket made of rubber, silicon, or other materials. In that case due to the soft material, it is possible to have some compensation also in the main axis but it is limited depending on the soft pipe socket material and its design (radius, diameter). This solution is usually expensive and is not good regarding acoustic performance because the soft materials are less efficient than the rigid one to filter the noise that goes inside the air pipe sockets.

[0007] It is an object of the present invention to design and arrange a connection between two components, especially between interfaces for air intake or exhaust systems that can compensate high deviations without the use of any soft material and without moving the components.

[0008] According to an aspect of the invention, the connecting device comprises at least one separate component which is mounted on the first pipe socket, wherein the separate component is rotatable relatively to the first pipe socket in the circumferential direction and is fixed to the first pipe socket in the axial direction. The two pipe sockets can be connected to each other and sealed together even when the two pipe sockets respectively the two exhaust components have different relative positions to each other. It is sufficient for the two pipe sockets to be inserted into one another by a minimum distance to create a tight connection. Within the dis- tance_D, the position of the two pipe sockets respectively the two exhaust components relative to one another can vary, and the connection still remains closed and tight. The tight connection is flexible in the axial direction. It is also essential to the invention that the two pipe sockets do not have to be twisted relative to one another for the connection. The distance_D is preferable between 1 mm and 40 mm. The connecting device is closing the connection and provides the two stop positions in that closed status with the distance_D in axial direction. This enables a connection between the two pipe sockets even if the two pipe sockets respectively the two exhaust components are at different distances in the axial direction. The connection is possible in the range over the distance_D defined by the two stops. This positive locking allows to reduce the number of components, to use no soft parts and improve the performance of the system.

[0009] Due to the inventive positive locking between the two pipe sockets, the locked and tight connection is movable in the axial direction. The connection of the two pipe sockets is tight in any of the possible positions between the two stop positions and during the movement between the two stop positions in the range of the dis- tance_D. At both stop positions the connection is locked in axial direction. The two pipe sockets are indirectly connected to each other by the connecting device. The tightly connected second pipe socket can be moved into several axial positions relative to the tightly connected first pipe socket. The tightness is provided with the sealing element that is arranged in the radial direction between the two pipe sockets. The sealing element allows axial displacement at least relative to one of the two pipe sockets or relative to both pipe sockets. A sealing element is to be understood as a seal for various fluids, in particular for hot air or gases including exhaust gases from combustion engines.

[0010] The tightness between the two pipe sockets is provided in any position in the range of the distance_D. This principle of being able to move the two pipe sockets relative to each other in a tight connection is also an essential inventive feature of the claimed method to compensate design-related dimensional deviations between two components.

[0011] The pipe socket can be a part of a device such as a pipe or an intake or an exhaust pipe socket or a housing of an intake or exhaust system or a pipe socket of an intake or exhaust device. Especially it is also provided, that the first pipe socket is a turbo outlet of a turbo charger and the second pipe socket is a pipe socket of a charge turbo-air-housing, each a component of a combustion engine. The axial direction, the radial direction, the circumferential direction (circumferentially) and the coaxial positions have a meaning in relation to the centre axis_C. A rotation or pivoting is also in relation to the centre axis_C and means the movement in circumferential direction. An axial movement is also in relation to the centre axis_C a movement in axial direction. For the purposes of the invention, an axial movement is to be understood as meaning the same as a translational movement.

[0012] It is advantageous in terms of tightness that the first pipe socket and the second pipe socket are rigidly fixed via the connection device with their two centre axes coaxial to each other and with respect to the angular position of the two centre axes. This connection prevents the two tubes from tilting relative to each other, ensuring that both centre axes are always coaxial. This ensures that the linear sealing surface formed by the elastic element on the cylindrical surface is circular. The elastic element is positioned at right angles to the centre axes and fits uniformly against the cylindrical sealing surface, thus achieving the best sealing effect. If the two pipes were to tilt from their coaxial angle to each other, the sealing surface would no longer be circular and would no longer be at right angles to the centre axes. In this case, the sealing element would not lie uniformly against the cylindrical surface and would therefore not provide the best possible seal.

[0013] The first pipe socket is inserted into the second pipe socket or the second pipe socket is inserted into the first pipe socket. A simple connecting device is possible for both options, which overlaps from one pipe socket to the other. Within the embodiment in which the first pipe socket is inserted into the second pipe socket, the connecting device forms with the end section of the first pipe socket a circumferential receptacle around the first pipe socket, so that the end section of the second pipe socket is inserted into the receptacle between the first pipe socket and the connecting device. In the embodiment according to which the second pipe socket is inserted into the first pipe socket, no receptacle is provided between the first pipe socket and the connecting device.

[0014] According to a relevant aspect of the invention the connecting device has a second component that is fixed to the second pipe socket, wherein the separate component and the second component can be directly positively locked to one another in both axial directions. This makes it possible for the two pipe sockets to be connected to each other indirectly in a positive locking manner. The positive locking connection between the two pipe sockets is thus made with the respective end section of each pipe socket, with which they are inserted into each other.

[0015] In relation to an easy closable connection, the two parts are connected to one another without tools and can be detached from one another without tools. A key aspect of the invention is that the tight connection, which is moveable in the axial direction, can be closed and released manually without a tool. A simple approach for this is a type of bayonet lock with a component that is for closing the connection to pivot or swivel around the centre axis C for less than 90 degrees. Alternatively, the connection can be made via a clip or a thread or any arrangement of plugs.

[0016] Regarding a bayonet lock, it is advantageous that the separate component on the first pipe socket is designed as a sleeve put on the first pipe socket and the second component arranged on the second pipe socket is designed as a projecting pin in the radial direction on the second pipe socket. A bayonet lock can be advantageously produced with such a sleeve that can be rotated or at least pivoted around the pipe socket. The sleeve is fixed to the pipe socket in an axial direction and has slots or grooves to insert the pin. The pin is integrated in the second pipe socket, for example in such a way that the second pipe socket and the pin are moulded as one component. By pivoting or swivelling the sleeve, the pin can be moved into the sleeve and into the slots or grooves. This movement is closing the sleeve with the pin in axial direction and is closing the connection.

[0017] For a straight connection with the pin assembled or moulded at the pipe socket it is advantageous that the sleeve protrudes in the axial direction on the end section of the second pipe socket or at least partly on the second pipe socket. This allows the sleeve to be connected directly to the second pipe socket.

[0018] The advantages of a bayonet lock are that the sleeve has a recess for the pin with at least two, preferred three adjoining sections, wherein the pin can be inserted into the first section from the outside in the axial direction, wherein the sleeve can be rotated relatively to the pin in the circumferential direction in the second section and wherein the pin can be moved relatively to the sleeve in the third section in both axial directions to a limited extent by the distance_D. The recess can be designed at least partially as a slot or at least partially as a groove. Fixing and centring the sleeve at the pipe socket is advantageously achieved in that, the sleeve has a bearing surface and has a contact with the bearing surface in the radial direction and in the axial direction against at least one surface of the first pipe socket. This ensures that the sleeve is centred in relation to the central axis on the surface of the first pipe socket. The second pipe socket is also centred by centring the sleeve. For this purpose, the second pipe socket is pipe socketed or plugged into the sleeve in a radial direction.

[0019] Simple centring is achieved in that, the bearing surface and the surface are preferably each conical or spherical. Such geometries allow bearing pipe socket in axial and radial directions together.

[0030] DETAILED DESCRIPTION

[0031] The perspective view according to fig. 1 shows a preferred embodiment of a movable and tight connection between a turbocharger 5 and an turbo-air-hous- ing 6 as hot air intake components of an internal combustion engine. Such exhaust components 5, 6 are connected via the respective pipe sockets 1 , 2 of the components and are assembled in the engine compartment of a motor vehicle. The two centre axis of the two pipe sockets are coaxial. The respective position of the individual exhaust component 5, 6 is exactly predetermined relative to the overall construction but not relative to each other. With these predetermined positions, there are dimensional deviations in the relative positions of the two components 5, 6 to each other in axial direction and thus also regarding the two pipe sockets 1 , 2 to be connected in various directions. When assembling the connection of the two pipe sockets 1 , 2 of the exhaust components 5, 6 the constructive deviations must be compensated. A connecting device 3 according to the invention enables such constructional deviations in the direction of the central axis C of several millimetres to be compensated for. For this purpose, it is provided that the two pipe sockets 1 , 2 can be tightly connected to each other in different axial positions. In such exhaust gas applications, thermally induced movements in the direction of the centre axis must also be compensated. The solution according to the invention enables a tight connection with such compensation without the use of elastic pipes.

[0032] Fig. 2a and 2b illustrate a sectional view of a movable and tight connection device 3 with the two pipe sockets 1 , 2 being connected to each other. The first pipe socket 1 is part of the turbo charger 5 and the second pipe socket 2 is part of the turbo air-housing 6. To connect the both pipe sockets 1 , 2 they are inserted into each other along an end section 1 .1 , 2.1 by a measure_M to guide fluids. The internal diameters of the two pipe sockets 1 , 2, which are not described in detail, are substantially the same size to minimise flow resistance. Depending on the deviation of the relative position of the first pipe socket 1 in relation to the second pipe socket 2 in the axial direction, i.e. in the direction of the centre axis C, the two end sections 1 .1 , 2.1 are inserted into each other to a greater or lesser extent. A sealing element 4 is provided in the radial direction between the two pipe sockets 1 , 2 to seal the connection. The basic principle of this connection is also shown schematically in figures 3 and 4. The embodiments shown in figures 3 and 4 differ in that the first pipe socket 1 is inserted into the second pipe socket 2 in figure 3 and the second pipe socket 2 is inserted into the first pipe socket 1 in the opposite way in figure 4.

[0033] Essential to the invention for all embodiments shown in Figures 1 to 7 is that a movement of the two pipe sockets 1 , 2 relative to each other is possible and limited by a distance_D. The connecting device provides two stops with that dis- tance_D. At both stop positions the connection is locked in axial direction. Therefore a connecting device 3 is provided that is positively coupling the two pipe sockets 1 , 2 to each other. That has the effect, that the connection is closed. The connecting device 3 is designed as a bayonet lock with a sleeve 3.1 with a recess 3.3 for a pin 3.2 of the pipe sockets 1 , 2. The recess 3.3 is formed from three adjoining sections 3.3a-3.3c. The three adjoining sections 3.3a-3.3c extend in axial direction or in circumferential direction and are adjacent to each other. The recess 3.3 respectively the adjoining sections 3.3a-3.3c are formed by grooves or slots in the sleeve 3.1 . The grooves and slots are connected to each other and form an H-shaped movement pattern. A total of four recesses 3.3 are arranged in the circumferential direction around this sleeve 3.1. In addition, four pins 3.2 arranged in the circumferential direction are provided, which engage in the adjoining sections 3.3a-3.3c. The sleeve 3.1 is fixed to one of the two pipe sockets 1 , 2 and the pin 3.2 is fixed to the other pipe socket 1 , 2 in the axial direction. The two pipe sockets 1 , 2 are indirectly coupled to each other by coupling of the sleeve 3.1 with the pins 3.2. For the coupling, the pin 3.2 is inserted into the sleeve 3.1 in several adjoining sections 3.3a-3.3c. Fig. 5a illustrates a movement pattern of the pin 3.2 relative to the sleeve 3.1 for the bayonet connection. In the first section 3.3a, the pin 3.2 moves in the direction of the centre axis C into the sleeve 3.1 . The sleeve 3.1 is then swivelled by a few degrees in the circumferential direction so that the pin 3.2 moves from the section 3.3a to the third section 3.3c within the second section 3.3b. After swivelling the sleeve 3.1 , the pin 3.2 is positioned in the third section 3.3c. The third section 3.3c has a length in the axial direction that corresponds to the sum of the distance_D and the diameter of the pin 3.2. In this position the pin 3.2 can move over the distance_D relatively to the sleeve 3.1 . A corresponding range of movement is provided for the two pipe sockets 1 , 2 relatively to each other. In total, according to the number of pins 3.2, four identical adjacent sections 3.3a-3.3c are arranged in the circumferential direction around this sleeve 3.1.

[0034] In the embodiment, shown in figures 2a, 2b and 3, the first pipe socket 1 is inserted into the second pipe socket 2 with the respective end section 1 .1 , 2.1 by a measure_M. The sealing element 4 is fixed to the inner surface 2.2 of the second pipe socket 2 in the axial direction. This fixation can be achieved by several separate components mounted in the second pipe socket 2 or via a circumferential groove in the second pipe socket 2. The sealing element 4 slides on an outer sealing surface 1 .3 of the first pipe socket 1 in the axial direction and seals the connection via this sealing surface 1.3. Accordingly the pin 3.2 is extending through the sleeve 3.1.

[0035] For all embodiments shown, the sleeve 3.1 is fitted and mounted on the first pipe socket 1 so that it is fixed in the axial direction relative to the first pipe socket 1 and it can rotate or swivel in the circumferential direction. The sleeve 3.1 is fixed in the axial direction by means of an assembly 3.5, which is not described in more detail and comprises a retaining ring on the sleeve 3.1 and a groove in the first pipe socket 1 in which the retaining ring engages. The sleeve 3.1 has a conical bearing surface 3.4 that is directed in axial and in radial direction. Together with a corresponding conical surface 1.2 of the first pipe socket 1 a bearing is provided in the axial and in the radial direction. The two conical surfaces 1 .2 and 3.4 provide additionally to an axial bearing also a centring of the sleeve 3.1 in relation to the centre axis C. The pin 3.2 is structurally integrated into the second pipe socket 2 and is not attached to the second pipe socket 2 as a separate component.

[0036] In the embodiment, shown in fig. 4a and 4b, the second pipe socket 2 is inserted into the first pipe socket 1 in the opposite manner. Accordingly, the pin 3.2 is longer in the radial direction and is extending beyond the sealing element 4 and the first pipe socket 1 through the sleeve 3.1 .

[0037] Once the connection has been assembled, i.e. after the two pipe sockets 1 , 2 have been inserted into each other and the bayonet lock has been closed, the pin 3.2 can only move in the axial direction within the third section 3.3c by the limited distance_D of several millimetres. So there is a movement of the two pipe sockets 1 , 2 between two relative positions P1 and P2 in axial direction. The movement in axial direction is possible in both axial direction a1 and a2. Accordingly, the relative movement of the two pipe sockets 1 , 2 is possible and limited by this distance_D between the two relative positions P1 and P2. This distance_D makes it possible to compensate for the deviation in the axial direction during assembly. The connecting device 3 limits the movement of the pipe sockets 1 , 2 to that distance_D, which is correspondingly smaller than the measure_M by which the two pipe sockets 1 , 2 are inserted into each other. Accordingly, the following applies: 1 mm < D < M. Not the measure of 1 mm is important, it is the solution that a movement is possible with that closed and tight connection. The range of this measure_M can be between 3 mm and 50 mm.

[0038] Figure 5 illustrates a perspective view of a sleeve 3.1 and the second pipe socket 2. When the two pipe sockets 1 , 2 are inserted into each other, the sleeve 3.1 is swivelled in the circumferential direction to such an extent that each of the four first sections 3.3a mate with one of the four pins 3.2 in the axial direction. The arrows depicted on the sleeve 3.1 show the movement pattern of the sleeve 3.1 relative to pin 3.2. This movement pattern is shown enlarged in figure 5a. The sleeve 3.1 moves relative to the pin 3.2 essentially parallel or in circumferential direction of the centre axis C. Figure 6 illustrates a perspective view on the backside of a sleeve 3.2, which is placed on the second pipe socket 2. The position of the sleeve 3.1 in relation to the second pipe socket 2 is identical to the position shown in figure 5.

[0039] Figure 7 illustrates a sectional view of the connection device according to the cutting line VI I- VI I of fig. 2b.
