Holder for mounting a fuel distributor to an internal combustion engine and system with such a holder

State of the art

The invention relates to a holder for fastening a component, in particular a fuel distributor, to an internal combustion engine and to a system which is preferably a fuel injection system or a part of a fuel injection system. Specifically, the invention relates to the field of fuel injection systems of internal combustion engines, wherein high pressure fuel is injected through fuel injectors into associated combustion chambers of the internal combustion engine. From DE 10 2010 046 344 A1 discloses an engine assembly with a fuel bar is known. The engine assembly includes a cylinder head, a cam cover and a

Fuel rail assembly. The fuel rail assembly includes the fuel rail, a bracket assembly, and a fuel injector. The fuel rail of the engine assembly is attached to the cam cover. Here, the staple assembly is fixed to the fuel bar, comprising a fastener and an insulating member. The fastener engages the cam cover and secures the fuel rail thereon. In one possible embodiment, the

Fastening assembly fasteners, spacers and a sleeve and a first and a second insulating member have. The fasteners have a head and a shank with a threaded portion having an opening in the

Cam cover is engaged to attach the fuel rail to the cam cover. The fastener extends through the sleeve. The first

Isolation element is axially between a first side of the bracket and the

Cam cover arranged. The second isolation member is disposed axially between the second side of the bracket and the head of the fastener. The

Insulation elements may be formed of an elastomeric material which provides for damping. The motor assembly known from DE 10 2010 046 344 A1 has the disadvantage that the insulation elements made of the elastomeric material are fastened by the head of the fastening element, which is screwed into the cam cover, via the spacer. Thus, by the fastener both the attachment to the

Cam cover as well as the fixation of the insulation elements. Since the tightening torque of the fastener must be large, thus two possible cases with respect to a dimensioning of the spacer are possible. If the spacer designed slightly too short, then there is a game of the clip between the insulation elements, which significantly affects the function, so this case is to be avoided. If the spacer is designed to be too long, taking into account possible tolerances, then there is a high local compression of the insulation elements, which can not be avoided due to the required high tightening torque. This high pressure then leads to a local component fatigue on the insulating elements, namely on the one hand in the region of the spacer and on the other hand on a stepped portion of a sleeve on which the first insulating element is supported. This results in tolerance due to a certain dispersion. Outer areas no longer contribute to the fixation of the clip relative to the insulation elements, since the support partners are missing

or the bias disappears. This also has an unfavorable effect on the possible vibration damping. This also leads to tolerance-related dispersion.

Disclosure of the invention

The holder according to the invention with the features of claim 1 and the

inventive system with the features of claim 8 have the advantage that an improved vibration damping is possible. Specifically, with respect to the particular application, a suitable adaptation of the vibration damping can be made. The measures listed in the dependent claims are advantageous

Further developments of the holder specified in claim 1 and the system specified in claim 8 possible.

The holder according to the invention can also be manufactured and sold independently of the component, in particular the fuel distributor. The component, in particular the fuel distributor, and the holding element are not necessarily here

Components of the holder according to the invention. Specifically, the holder during assembly of the system, in particular a fuel injection system, to an internal combustion engine be connected on the one hand with the component and on the other hand with the internal combustion engine. During assembly, the connection of the biasing member can then be made with the fastening body. By the connection of the biasing member with the

Fixing body is then given the arrangement (position) of the biasing member relative to the mounting body and set the bias of the decoupling element. In this case, the biasing element can be acted upon, for example via a mounting device with a force that determines the bias of the decoupling element.

Meanwhile, the connection between the

Biasing element and the fastening body are configured. after the

Connection is configured, then the assembly force can be reduced again. Here is the tightening torque for the fastener or a through the

Fixing means generated fastening force for fastening the fastening body to the internal combustion engine, regardless of the mounting force for biasing the

Decoupling element. This is because the fastener and the

Mounting body lie in a force path, which is independent of a force path in which the biasing element, the decoupling element and the fastening body are. The traction takes place here only both times on the mounting body.

The plant is preferably as a fuel injection system or part of a

Fuel injection system designed. Thus, it is preferably a

Plant which is a fuel injection system or part of a fuel injection system. The internal combustion engine or parts of the internal combustion engine are not necessarily components of the system. However, a part of the holder, in particular the fastening body or a part of the fastening body, may also be attached to the internal combustion engine, for example by pre-assembly. Furthermore, the holder can also have more

Components, in particular attachments, be connected to the internal combustion engine. Thus, an adaptation to the particular application is possible. The holding element can be configured as a separate holding element and connected to the component, in particular the fuel distributor. However, the retaining element can also be a

Component of the component, in particular the fuel distributor, be. For example, the holding element by a suitable molding of a housing part of

Component be formed. Thus, in this regard, a broad scope is given. It is advantageous that the biasing element has an inner contact surface, with which the biasing element rests against an outer surface of the fastening body. As a result, a guide of the biasing member is ensured on the outer surface of the fastening body before the connection of the biasing member with the fastening body. In the Actuation of the biasing element, which serves to bias the decoupling element, thus a uniform force on the decoupling element is possible.

As a result, in particular a tilting of the biasing element is avoided, which leads to an uneven loading of the decoupling element.

Furthermore, it is advantageous in this case that a recess is provided on the outer surface of the fastening body, that the biasing element has a deformable projection and that the deformable projection and the recess of the fastening body are configured such that the biasing element can be connected by crimping with the fastening body. In this case, several recesses may be provided, the

preferably circumferentially distributed with respect to a longitudinal axis of the fastening body on the outer surface of the fastening body. This allows an advantageous connection, since in this way the individual attachment points, which are configured by crimping, at least approximately parallel to the longitudinal axis are loaded and a tilting moment between the biasing member and the fastening body, which occurs at a single connection point, is avoided. Through the leadership of the

However, biasing member on the outer surface of the fastening body can also by a single connection point at which the connection between the

Preload element and the fastening body is designed by crimping, a reliable connection can be ensured if it is possible in a specific application.

It is also advantageous that the inner contact surface of the biasing member and the outer surface of the mounting body are configured so that between the inner bearing surface of the biasing member and the outer surface of the

Fastening body is formed a sliding seat. In this embodiment, as close as possible guidance of the biasing member on the outer surface of the

Fastening body achieved, so that in the bias the desired end position in which the connection of the biasing member is designed with the fastening body can be easily held without it during the connection to

Relative movements between the biasing member and the fastening body comes. This facilitates the design of the connection between the biasing member and the mounting body and allows depending on the connection, in particular in a welding, a high quality of the connection.

In a further embodiment, it is advantageous that the inner contact surface of the biasing member and the outer surface of the fastening body are configured so that the biasing member by a between the inner bearing surface of the Biasing element and the outer surface of the fastening body formed press fit with the fastening body is connectable. By the press fit alone or

optionally be ensured in conjunction with a further connection method, the bias of the decoupling element.

It is advantageous that a support element is provided, that the support element is connected to the fastening body or is covered by the fastening body and that the decoupling element of the biasing element at least indirectly against the

Supporting element is prestressed. The support member may thus be connected as a separate part in a suitable manner with the fastening body or part of the

Be fastening body. The biasing member may be supported directly or indirectly on the support member. In the prestressed state of the decoupling element thus a frictional connection on the support member and the fastening body is achieved. The decoupling element is designed in an advantageous manner annular. As a result, the decoupling element can enclose the fastening body circumferentially. In this way, in particular a rotationally symmetrical configuration of the decoupling element can be ensured, resulting in a correspondingly symmetrical behavior for vibration damping. However, it is also advantageous that the decoupling element is configured as an annular decoupling element bent at least approximately rectangularly. This allows a special non-symmetric Wrkungsweise be specified for vibration damping. This is advantageous, for example, in accordance with different loads. For example, an as

Fuel distributor strip ausgestalteter fuel distributor to be attached via a plurality of holders on the internal combustion engine. Here are different

Vibration loads in the different spatial directions. specially

If necessary, the vibrations or the differ

Vibration components in the three mutually perpendicular directions in space, one of which is oriented along the fuel distributor and is oriented parallel to the longitudinal axis of the fastening body. Regarding the three defined thereby

Spaces can be adjusted by the shape of the decoupling element then different spring constants of the elastic coupling via the decoupling element. It is also advantageous that the decoupling element is designed so that at least along a biasing direction in which is biased by the arrangement of the biasing member relative to the fastening body, the decoupling element, a non-linear spring characteristic is predetermined, which has a function of acting on the holding element Restoring force of a deflection of the retaining element relative to the fastening body describes. By biasing a starting point on the non-linear spring characteristic can then be set, so to speak. This can also be a

frequency-dependent stiffness curve and a frequency-dependent attenuation by the adjustability of the bias and possibly the geometry of

Decoupling be dynamically tuned. This results in an adjustable or tunable transfer function.

Thus, the acoustic behavior of the system, in particular the

Fuel injection system, to be improved. Furthermore, the stress on the components used by the assembly and by operating temperatures can be reduced. The decoupling elements are in this case designed in an advantageous manner as spring elements. In particular, viscoelastic decoupling elements can be used. With regard to the respective application, a single decoupling element per holder can also be used. The attachment is preferably via a plurality of holders.

By means of the decoupling element or the decoupling elements, therefore, mechanical and optionally also thermal and geometrical decoupling of the component to the internal combustion engine is provided in at least one spatial direction. Furthermore, a defined, mechanically damping behavior of the decoupling in the individual spatial directions is possible. Due to the adjustment process during assembly, the

Biasing the decoupling elements or the decoupling element. This adjustment process is independent of the fastening force, by the

Fastener is applied. The bias voltage can in this case in one or more spatial directions via one or more intermediate elements, in particular the

Holding element, carried out, one of the tolerances of the individual components

independent bias can be adjusted.

Thus, the requirements for the production of tolerances of the individual components are reduced.

The bias voltage can be controlled to a certain extent, for example via a

Sliding seat, and / or fixed by welding, crimping or other material or positive locking. A positive connection can also be achieved via a thread, which is designed between the biasing member and the fastening body. In such an embodiment, an adjustability can also be realized. As a result, the bias can be adjusted after a certain period of use. However, a setting regarding an anticipated aging of the decoupling element is possible.

The execution of the preferably viscoeleastic decoupling by the at least one decoupling element can also take place without helical fastening. Here is a snapping, clamping or integration of the decoupling in existing attachments, such as an intake module, a valve cover, a camshaft transmission and other attachments, also possible.

Embodiments of the invention 1 shows a system 1 with a holder 2 and a fuel distributor 3, in particular a fuel distributor strip 3, and a part of an internal combustion engine 4, in particular a cylinder head 4, in an excerptional, schematic sectional view

according to a first embodiment. The plant 1 is preferably a fuel injection system 1 or a part of a fuel injection system 1.

The holder 2 has a fastening body 5, a fastening means 6, a retaining element 7, decoupling elements 8, 9 and a biasing element 10. The fastening means 6 is screwed into a threaded bore 11. A covenant 12 of the head 13, as

Screw head 13 is configured, is located on an end face 14 of the mounting body 5 at. As a result, the fastening body 5 is acted upon by its underside 15 against a surface 16 of the internal combustion engine 4. In this case, the fastening force is generated by a tightening torque of the fastener 6 designed as a fastening means 6. This results in a frictional connection via the fastening means 6 and the fastening body 5, which is illustrated by a closed curve 17.

The biasing element 10 has an inner contact surface 20. The

Biasing element 10 is arranged on an outer surface 21 of the fastening body 5. Here, the biasing member 10 is located with its inner contact surface 20 on the outer surface 21 of the mounting body 5. During assembly, the biasing member 10 is displaceable in and against a biasing direction 22 relative to the mounting body 5, wherein a guide on the outer surface 21 takes place. The biasing direction 22 is in this case oriented parallel to a longitudinal axis 23 of the fastening means 6. The holder 2 also has a support element 24 which in this embodiment is encompassed by the attachment body 5. In a modified embodiment, the support member 24 may also be connected to the attachment body 5. The underside 15 is at least partially formed on the support member 24 in this embodiment. Thus, the support member 24 is supported on the surface 16 of the internal combustion engine 4.

The biasing member 10 has a formation 25, which is designed as a recess. Furthermore, the decoupling element 8 has a formation 26, which is designed as a bulbous shape 26. With the bulbous formation 26 is the

Decoupling element 8 inserted into the biasing member 10, so that a positive connection is formed. The formations 25, 26 may also be formed adapted to each other in another way to form a positive connection. The support member 24 has a formation 27, which is designed as a recess. Furthermore, the decoupling element 9 has a formation 28 which is bulbous

is designed. With the bulbous formation 28, the decoupling element 9 engages in the formation 27, so that a positive connection is formed. The holding element 7 is arranged between the decoupling elements 8, 9, wherein in this embodiment, an upper side 29 of the holder 7 is at least approximately configured flat. Furthermore, an underside 30 of the holder 7 is at least approximately planar.

Between the decoupling element 8, which rests against the upper side 29, and the holding element 7, is thus in a direction 31 which is perpendicular to the biasing direction 22, a

Friction formed. Accordingly, a frictional engagement in the direction 31 is formed between the decoupling element 9, which bears against the underside 30, and the holding element 7. By means of a bias voltage of the decoupling elements 8, 9, a sufficient holding force in and against the direction 31 can be generated within certain limits. Optionally, a positive connection between the holding element 7 and at least one of the decoupling elements 8, 9, as it is based on the

Embodiments 25 to 28 is described by way of example.

During assembly, the biasing member 10 is acted upon in the biasing direction 22 with a suitably selected mounting force. As a result, the decoupling element 8, 9 are biased. In this case, it is utilized that the biasing element 10 relative to the

Fixing body 5 is displaceable, so that the arrangement of the biasing member 10 is predetermined relative to the mounting body 5 during assembly. In this predetermined arrangement or position of the biasing member 10 relative to the

Fixing body 5 is then the connection of the biasing member 10 with the mounting body 5. As a result, the bias of the decoupling elements 8, 9 is set.

In this way, for example, in the context of a series production, a predetermined bias voltage of the decoupling elements 8, 9 can be set independently of occurring component scatters. In addition, it is also possible to individually set a desired pretension in relation to the particular application. Furthermore, a modular design can be realized in which, for example, the holding element 7 and / or the decoupling elements 8, 9 are dimensioned differently with respect to the respective application. Even with such a modular structure can then always the

desired bias can be adjusted. The adhesion of the biasing member 10 via the decoupling element 8, the

Retaining element 7 and the decoupling element 9 on the support member 24 is above the

Fixing body 5 is closed, as it through the closed curve 32nd

is illustrated. The bias of the decoupling 8, 9 and the application the decoupling 9, 9 in operation at a deflection of the support member 7 relative to the mounting body 5 is thus independent of the attachment of the

Fixing body 5 on the internal combustion engine 4, as illustrated by the closed curve 17.

If the predetermined bias of the decoupling elements 8, 9 is set by the arrangement of the biasing member 10, then the biasing member 10 is preferably fixed in position. This can be done by a material and / or positive connection. In a modified embodiment may be formed between the biasing member 10 and the mounting body 5 and a press fit. For this purpose, the inner bearing surface 20 of the biasing member 10 and the outer surface 21 of the

Fixing body 5 designed so that the biasing member 10 formed by the between the inner contact surface 20 of the biasing member 10 and the outer surface 21 of the mounting body 5 press fit after assembly with the

Fastener 5 is connected. Depending on the application, this can also be combined with another type of connection. The decoupling elements 8, 9 are then biased over the service life of the biasing member 10 against the support member 24. In this embodiment, the decoupling elements 8, 9 surround the

Fastener 5 circumferentially. The decoupling elements 8, 9 are in this case designed as annular decoupling elements 8, 9 and preferably designed rotationally symmetrical with respect to the longitudinal axis 23. At least a part of the retaining element 7 in the region of cooperation with the decoupling elements 8, 9 is preferably also designed annular. Accordingly, the biasing member 10 and the support member 24 are preferably configured rotationally symmetrical with respect to the longitudinal axis 23.

In the design of the connection between the biasing member 10 and the mounting body 5, it is also possible that during assembly, a distance 33 between the biasing member 10 and the support member 44 is predetermined. During assembly, the bias can then be adjusted by the mounting device

Preload element 10 adjusted in the predetermined by the distance 33 arrangement (position) relative to the mounting body 5. The distance 33 may in particular be a fixed press-fit dimension 33 if the connection of the pretensioning element 10 to the fastening body 5 takes place by means of an interference fit. Thus, one is

position-controlled adjustment of the bias of the decoupling 8, 9 possible. Fig. 2 shows a system 1 with a holder 2 and a fuel distributor 3 and an internal combustion engine 4 in a partial, schematic sectional view according to a second embodiment. In this embodiment, the fastening body 5 has on its outer surface 21 at least one recess 40. Furthermore, the biasing element 10 has a deformable projection 41, which at least in the region of the recess 40 of the fastening body 5 on the outer surface 21 of the

Fixing body 5 is provided. Preferably, the deformable lug 41 of the biasing member 10 encloses the outer surface 21 of the mounting body 5 circumferentially. The inner bearing surface 20 of the biasing member 10 is preferably on the outer surface 21 of the mounting body 5 at. However, the inside can be

Contact surface 20 also be slightly spaced from the outer surface 21.

During assembly, the biasing element 10 is first acted upon in the biasing direction 22 by a mounting device. This can be controlled by force. A distance-controlled adjustment of the pretensioning of the decoupling elements 8, 9 can also be achieved via a defined distance 33. In the given arrangement of

Preload element 10 relative to the mounting body 5, the deformable lug 41 during assembly by a crimping tool 42, which is applied in the region of the recess 40 and is acted upon in a direction 43 with a crimping force, slightly deformed into the recess 40. Thus, a positive connection is realized by crimping. In the given

Arrangement of the biasing member 10 relative to the mounting body 5, in which the connection of the biasing member 10 with the fastening body 5 is carried out by crimping, the bias of the decoupling elements 8, 9 is set after assembly. Fig. 3 shows a holder 2, the plant 1 shown in Fig. 1 in an excerptive, schematic sectional view corresponding to a third embodiment. In this embodiment, the biasing member 10 is first in the

Biasing 22 acted upon by a mounting force. As a result, the bias of the decoupling elements 8, 9 is set. Then, the biasing member 10 is connected to the fixing body 5 by a weld 44. Thus, a cohesive

Connection of the biasing member 10 with the mounting body 5 in the predetermined arrangement of the biasing member 10 is formed relative to the mounting body 5.

Fig. 4 shows a holder 2 of the system 1 shown in Fig. 1 in an excerptive, schematic sectional view according to a fourth embodiment. In this embodiment, the fastening body 5 on its outer surface 21 has an external thread 45. Furthermore, the biasing element 10 on an inner surface 20 'has an internal thread 46. With the internal thread 46, the biasing element 10th screwed onto the external thread 45 of the fastening body 5. About the

Thread connection between the biasing member 10 and the mounting body 10 is formed a positive connection. Here is a Nachstellbarkeit after a certain

Useful life or anticipated aging possible. The screwing of the biasing member 10 on the mounting body 5 can be carried out here to a predetermined distance 33. Thus, the bias of the decoupling 8, 9 is adjustable. Optionally, the biasing member 10 may also be fixed in position in a suitable manner. FIG. 5 shows the holder shown in FIG. 1 in an excerptional, schematic illustration from the viewing direction designated V according to a fifth

Embodiment. In this embodiment, a non-rotationally symmetric design is realized. The biasing element 10 and the decoupling elements 8, 9 are in this case bent at least approximately rectangular and annular. Between the inner bearing surface 20 of the biasing member 10 and the outer surface 21 of the mounting body 5 is formed by a corresponding configuration, a sliding fit. In the predetermined arrangement can then be configured in a suitable manner, a fixation of the biasing member 10 to the mounting body 5. By a corresponding formation of at least one decoupling element 8, 9, in particular along the biasing direction 22, a non-linear spring characteristic

be given that a dependence of acting on the holding member 7

Restoring force of a deflection of the retaining element 7 relative to the fastening body 5 describes. For example, in the described with reference to FIG

Entkoppelelement 8 a chamfer 50 is provided, whereby when adjusting the

Holding member 7 against the biasing direction 22, the spring constant gradually increases, since the chamfer 50 is increasingly suppressed. Thus, by the formation of the decoupling element 8 at least along the biasing direction 22, in which the decoupling element 8 is biased by the arrangement of the biasing member 20 relative to the mounting body 5, a non-linear spring characteristic can be specified.

By biasing a starting point is then set to a certain extent on this non-linear spring characteristic. By suitable shaping of the decoupling element, such non-linear spring characteristics can also be predetermined in other spatial directions.

The invention is not limited to the described embodiments.
