Disclosure of Invention

The object of the invention is to provide an elastic bearing element, in particular for an exhaust system, which has a simple construction and can be produced in a simple manner.

This object is achieved with a resilient supporting element having the features of claim 1.

Further embodiments are given in the appended dependent claims.

The elastic support element according to the invention comprises:

at least one fixing element for fixing the support element to the holder, and

at least one elastic element, in which at least one receiving opening is formed for receiving the fastening means,

wherein the at least one spring element is mounted in a predetermined fixing region of the at least one fixing element, the at least one spring element extends from the predetermined fixing region in the direction of the at least one receiving opening, and the predetermined fixing region and the at least one receiving opening are arranged offset from one another at a predetermined axial displacement at least in the axial direction of the fixing element.

The fastening region of the spring element on the fastening element and the receiving opening formed in the spring element are arranged offset from one another in the axial direction by a predetermined amount of axial displacement. The spring element extends in the axial direction from the fastening region to an accommodating section, in which an accommodating opening is formed. The receiving opening can be of cylindrical design. By fastening and forming the spring element on the fastening element, a predetermined deflection behavior of the receiving opening in the spring element relative to the fastening element is provided. In the case of the use of an elastic bearing element, the fastening means of the exhaust system are accommodated in the receiving opening.

The exhaust system and the bolt move in the receiving opening due to vibrations and impacts occurring during operation of the vehicle. The receiving opening or the spring element is deflected relative to the fastening element by a movement of the pin in the receiving opening. The elastic element can compensate or absorb vibrations and impacts, thereby preventing the transmission of vibrations to the frame and the body. The spring element constructed in this way does not require a stiffening element or the like in the region of the receiving opening, which must be completely embedded in the spring material of the spring element. The strength or rigidity provided by the spring element, in particular in the region of the receiving opening, is sufficient to enable the fastening element of the exhaust system to be fastened and held on the support element.

The fixing element can be tubular or sleeve-shaped in cross section. The securing element may be configured for receipt in the retainer. The fixing element can be pushed or inserted into the holder, for example. The fixing element can be made of synthetic material or the like. The fixing element can also be conical or spherical in shape. The outer circumferential surface of the fixing element may be conically widened. The inner circumferential surface of the fastening element can likewise be conically widened. In addition, it is conceivable for the outer and inner circumferential surfaces to be conically widened and for the fixing element to have a conical configuration overall.

The fixing element can be connected with the elastic element by vulcanization. In the fastening region, the elastic element can be connected to the fastening element in a planar manner. In the fixing region, the elastic element can be terminated in the direction of the axial end of the fixing element. In other words, the material thickness of the elastic element on the inner circumferential surface of the fixing element decreases in the direction of the axial end of the fixing element. With such a run-out, the stresses occurring in the spring element can be shared, so that stress peaks in the region of the spring element are avoided.

The fastening region can be arranged on an end section of the fastening element. For example, the fastening region can extend radially into the fastening element at a predetermined distance from the end edge of the fastening element, for example like a flange. The fastening element and the spring element can be designed in such a way that the fastening element can limit the deflection of the spring element and in particular of the receiving section with the receiving opening relative to the fastening element. The fastening element can thus serve as a stop for the spring element or to limit the deflection of the spring element when the exhaust system is deflected to a greater extent. For example, the elastic element can be accommodated in the fixing element. The fastening element can substantially completely surround the spring element, i.e. extend radially outwards around the spring element. The end section of the receiving opening or receiving section can project axially from the fastening element. No overlap occurs in the axial direction between the axial extent of the fastening region and the axial extent of the receiving opening. The fastening region can also be arranged centrally in the fastening element.

The at least one spring element can be designed in such a way that the center axis of the receiving opening and the longitudinal axis of the fastening element are offset in the radial direction and extend parallel to one another. However, the spring element can also be designed such that the receiving opening and the fastening element are arranged coaxially. The spring element can be designed at least in sections in the form of a truncated cone or in the form of an oblique truncated cone. Adjoining the truncated-cone-shaped section is a tubular section which forms an end section for receiving the section. Starting from the fastening region, an opening can extend through the spring element, which opening merges into the receiving opening or opens into the receiving opening. The receiving opening can be of cylindrical design in order to be able to receive a fastening mechanism of the exhaust system. The receiving opening can be provided with at least one stop or at least one stop surface. The stop surface can be contacted by a fastening means which is to be received in the receiving opening. With the stop face, the fixing means can be prevented from sliding axially in the receiving opening. The fastening means may be, for example, a fastening bolt or a fastening tube of an exhaust system of a vehicle. A dart-like positioning projection may also be arranged on the elastic element.

The resilient element may have radially extending segments. The end face of the radial section of the spring element facing away from the receiving opening can be provided with a recess. The recess can extend along the inner circumferential surface of the fastening element at a predetermined radial distance from the inner circumferential surface. The radial extent of the radially extending segments may substantially correspond to the extension extent of the fastening area. The fixing region may be formed by a predetermined segmentation of the inner circumferential surface of the fixing element.

The spring element can extend from the radial section in the direction of the longitudinal axis of the fastening element toward the receiving opening. Starting from the fastening region, the spring element can initially extend in the radial direction and in contact with the radial segments substantially in the axial direction in the direction of the receiving opening. At the transition of the radial section to the section extending substantially in the axial direction, a recess forming an undercut or a back recess may be provided in the spring element.

The fixing element may have a first end section and a second end section. The fastening region for the spring element can be arranged in the first end section of the fastening element, and the receiving opening can be arranged in the first end section of the fastening element. The end segments are arranged on opposite ends of the fixing element. The securing element may substantially completely surround the resilient element. It is possible for the section of the receiving opening formed in the spring element to project from the fastening section. For example, a section of the receiving opening provided with a chamfer can project from the fastening element.

The elastic element can extend from the fastening region on the inner circumferential surface of the fastening element at a radial distance along the inner circumferential surface. The radial distance can increase from the fastening region in the direction of the receiving opening and can vary in the circumferential direction of the fastening element. This can be found in particular in the case of an asymmetrical design of the spring element.

In the fastening region, at least one projection projecting radially inward can be formed. A protrusion protruding radially inward may be provided on the inner circumferential surface of the fixing member. A plurality of protrusions protruding radially inward may also be provided on the inner circumferential surface of the fixing member. The one or more protrusions serve to assist in the fixing of the resilient element on the fixing section of the fixing element. The radial projection can be used in particular for axially securing the elastic element to the fastening element.

The fixing region may be formed by at least one land on the inner circumferential surface of the fixing element. The axial extension of the platform may correspond to the axial extension of the radial segments of the elastic element. The platform projects radially inwardly from the inner circumferential surface only. The platform may be used to die cast elastomeric materials in a vulcanization tool.

In a receiving opening formed in the spring element, a bushing can be received. The sleeve may be substantially tubular, conical or spherical in configuration. The bushing may be a sliding bushing. Accordingly, the bushing can form a sliding bearing for the fastening means of the exhaust system, which fastening means are to be accommodated in the bushing or in the accommodating opening. The inner circumferential surface of the sleeve can be provided without an elastic material for the elastic element. At least one radial projection may be formed on the sleeve. The protrusions may protrude radially outward from an outer circumferential surface of the boss. The protrusion may be arranged in a central region of the sleeve. The protrusions are used to provide support for the sleeves on the resilient elements. A plurality of protrusions may also be provided on the sleeve. The projections may be offset from each other by a predetermined angle and extend away from the outer circumferential surface of the sleeve. Instead of one or more radial projections, a circumferential recess or a plurality of recesses can also be formed on the sleeve.

At least one stop element can be formed on the elastic element. The stop element can extend in the direction of the inner circumferential surface of the fixing element. The spring element can be supported on the fastening element by means of a stop element. The stop element can be arranged annularly around the receiving opening and project radially. A plurality of stop elements may also be provided, which are each arranged at a predetermined angle offset from one another about the center axis of the receiving opening. In this case, the stop element can be designed as a ring segment. In addition, a stop element which projects in the direction of the spring element can be formed on the inner circumferential surface of the fastening element. The stop element may run continuously along the inner circumferential surface of the fixing element. The stop element may be formed from an elastic material. In this case, it is also possible to provide a plurality of stop elements on the inner circumferential surface of the fixing element. The stop element serves to form a damping limitation for the deflection of the spring element relative to the fastening element, irrespective of whether the stop element is formed on the spring element or fastened to the fastening element.

In order to position the fastening element on the holder, the fastening element can have at least one stop element and/or an arching or an upper arching on its outer circumferential surface. The section of the fastening element between the stop element and the raised portion, i.e. the section of the fastening element that is cylindrical in shape, can be accommodated in the holder. The stop element is used in particular for: the support element or the fastening element can be mounted on the holder in a predetermined position thereof. Instead, the bulge can serve to fix the support element in its predetermined position on the holder. The stop element can be designed in the form of one or more radial projections or circumferential flanges with a round or irregularly shaped contour.

The receiving opening and the fixing element may be arranged coaxially. In this case, the elastic bearing element can be designed symmetrically or rotationally symmetrically.

The inner circumferential surface of the fixing element may be covered with a layer of an elastic material. The layer of elastic material can extend from the fastening region along the inner circumferential surface of the fastening element. The layer of elastic material can also be thickened in places in order to form the stop element.

The fastening element can be of substantially sleeve-like or tubular design. The fastening element may be of substantially cylindrical design. At least at one end of the fixing element there may be a segment extending radially inwards. An elastic element for the fastening region can be fastened to the radial segment. In addition, fastening regions can be provided on the radial sections of the element, by means of which the elastic element can be fastened to the fastening element. The radial segments may constitute openings that are contiguous with openings extending through the resilient element. The radial section may be arranged on the end of the fixing element opposite the end with the receiving opening. Accordingly, the element for supporting the element can be of substantially tubular, sleeve-like or cylindrical design. The fastening element and the sleeve which can be arranged in the receiving opening can each be provided with the elastic material of the elastic element only on one circumferential surface thereof. In addition, it is conceivable that both circumferential surfaces of the fastening element and/or the sleeve are provided at least in sections with the elastic material of the elastic element.

The spring element configured as described above can also realize in its shape: it is not necessary to provide reinforcing elements and structural elements in the receiving openings or receiving sections. The elastic element may be embodied without reinforcing elements or structural elements in the receiving opening or in the receiving section. In particular, no reinforcing element or structural element is embedded in the elastic material of the elastic element in the receiving section. This applies in particular to stiffening or structural elements constructed from materials other than elastic materials. The sleeve which can be accommodated in the receiving opening serves only for supporting the fastening means of the exhaust system. For this purpose, the bushing can be designed as a plain bearing.

The fixing element may have a radial section on which the fixing region is arranged. Starting from the fastening region provided on the radial segment, the spring element can extend in the direction of the receiving opening. The radial segments may extend substantially perpendicularly or obliquely with respect to the central axis of the fixing element. The fixing area may be formed by at least one section of the face on the radial section of the fixing element. The surface on which the fastening region is arranged can extend substantially perpendicularly or obliquely with respect to the center axis of the fastening element. The fastening region and the end face of the receiving section of the spring element having the receiving opening can be arranged offset from one another about a predetermined amount of axial displacement.

The invention also relates to an elastic bearing element, in particular for an exhaust system of a vehicle, having:

at least one fixing element for fixing the support element to the holder, and

wherein the at least one spring element is mounted on a predetermined fastening region of the at least one fastening element, the at least one spring element extending from the predetermined fastening region in the direction of an accommodating section having at least one accommodating opening, the accommodating section having an end face, the end face of the accommodating section being arranged offset with respect to the fastening region by a predetermined amount of axial displacement.

The predetermined amount of axial displacement can be set between the end face of the receiving section of the spring element with the receiving opening and the radial section of the fastening element with the fastening region. The predetermined amount of axial displacement can be adjusted between a face of the radial segment with the fastening region and an end face of the receiving segment with the receiving opening.

On the fastening element, a connecting element can be provided, which is designed to establish a connection with a component such as a holder. In this context, a similar component may be, for example, a cable guide. Such a cable guide may be used for guiding cables in a vehicle or building. In a vehicle, the cable guide can be fastened to a section of the vehicle body or the vehicle frame by means of an elastic support element. The connecting element can be designed in the form of a latching projection. The latching projections can extend in the axial direction of the elastic support element. The detent projection may have a detent lug. The detent lug can extend radially outward. The latching projections can be formed offset with respect to one another on the fastening element. In particular, the latching projections can be arranged offset to one another in the circumferential direction of the elastic support element. Between the latching projections, stop elements can be provided, which can be brought into contact with a holder or the like. The elastic support element thereby assumes a predetermined position on the holder or the like.

The receiving opening can have at least one coupling element which extends radially from an inner circumferential surface of the receiving opening and is designed to couple the elastic supporting element to the fastening means. The fastening means may in particular be bolt-like fastening means, such as bolts. The at least one coupling element on the inner circumferential surface of the receiving opening can be configured, for example, in the form of a web, a ridge, a bulge, a lip or a detent lug. The coupling element on the inner circumferential surface of the receiving opening can be constructed integrally with the elastic element. In this case, the coupling element can be formed in the form of a circumferential bulge on the inner circumferential surface of the receiving opening. A plurality of domes may be provided on the inner circumferential surface of the receiving opening. The at least one coupling element serves to simplify the fastening of the elastic support element to the fastening device. The elastic support element is coupled to the fastening means by means of a coupling element. In this way, the two hands of the assembler are freed for the final fastening of the elastic support element to the fastening device or for the connection of the elastic support element to another component before the final fastening. The at least one coupling element thus achieves a pre-fixing on the fixing means, so that the assembly can be simplified.

As already mentioned, a bushing can be provided in the receiving opening. At least one coupling element can be arranged on the inner circumferential surface of the sleeve. The coupling member may be formed of a lintel to an inner circumferential surface of the boss. The crosspieces can be made of a resilient material. The crosspiece can be constructed integrally with the bushing. The crosspieces may extend radially inwards from the inner circumferential surface of the sleeve. The lintel may extend in the axial direction. The crosspieces can be arranged on the inner circumferential surface of the sleeve offset from one another in the circumferential direction of the sleeve. The coupling element can also be formed by a detent element. The detent element can be arranged together with the crosspiece on the inner circumferential surface of the sleeve. In this case, the crosspieces and the latching elements can be arranged alternately in the circumferential direction on the sleeve. The detent elements can be detent projections which extend axially and/or radially. The detent projection can have a detent lug projecting radially inward on its end.

The invention also relates to a holder for a resilient support element having a resilient support element according to the aforementioned type. The holder can be used in particular for fastening the elastic support element to the vehicle.

The elastic support element can be connected to the holder by a press connection. However, other connection arrangements for connecting the elastic support element to the holder are also conceivable.

The invention also relates to an exhaust system for a vehicle having a bearing element of the aforementioned type.

The invention also relates to a vehicle having an exhaust device or a holder of the aforementioned type.

Detailed Description

Fig. 1 shows a perspective view of a support element, generally indicated at 10, according to a first embodiment of the invention.

The support element 10 has a fixed element 12 and a resilient element 14. The elastic element 14 is arranged in the fixing element 12 in a sleeve-like configuration and is accommodated. The fixing element 12 has a first end section 16 and a second end section 18. On the outer face of the first end section 16, a bulge or elevation 20 can be seen, which serves to fix the bearing element 10 on a holder (not shown) for mounting the bearing element 10 on a vehicle (not shown). The protuberance 20 can also be used to snap into the interior of the holder.

In the second end portion 18, a fastening region BB is formed, on which the spring element 14 is connected to the fastening element 12. On the second end section 18 of the fastening element 12, a stop element 22 is provided. With the stop element 22 it can be ensured that: the support element 10 is fixed or fastened in its predetermined position on a holder (not shown). For example, the holder can receive a portion of the fastening element 12 extending between the stop element 22 and the bulge 20 for mounting the support element 10 on the vehicle. In the second end section 18, on the inner circumferential surface 24 of the fixing element 12, the elastic element 14 is mounted in the fixing region BB. The fixing region BB is formed by a section of the inner circumferential surface 24 of the fixing element 12. An opening 26 extends through the spring element 14, said opening transitioning into a receiving opening (see fig. 2). The receiving opening is used for receiving a fastening mechanism of an exhaust system of a motor vehicle.

Fig. 2 shows a further perspective view of the support element 10. Fig. 3 shows a front view of the support element 10. The support element 10 is viewed in fig. 3 from the direction of the first end section 16. Fig. 4 shows a sectional view in the sectional direction IV-IV in fig. 3.

Radially inside the first end portion 16, a receiving portion 28 of the spring element 14 is arranged. In the receiving portion 28, a receiving opening 30 is formed for receiving a fastening mechanism of an exhaust system of a vehicle. The receiving opening 30 is of cylindrical design. End section 28 of receiving section 28₁(fig. 4) is of tubular construction. At the end face 28 of the receiving section 28₂At the transition to the receiving opening 30, a chamfer or conical section 32 is formed. The receiving section 28 or its outer circumferential surface is radially spaced from the inner circumferential surface 24 of the fixing element 12. End face 28 of receiving segment 28₂With a predetermined amount of axial displacement AV_SBSpaced from the fixed area BB.

The inner circumferential surface 24 of the fixation element 12 is coated with a thin layer 36 of an elastic element. The thin layer 36 is made of the same material as the elastic element 14. Proceeding from the first end portion 16, between the layer 36 of elastic material on the inner circumferential surface 24 of the fastening element 12 and the elastic element 14, a cavity 34 extends in the direction of the second end portion 18.

The bulge or bead 20 is formed around the outer circumferential surface 38 of the fastening element 12. The stop element 22 corresponds to a projection which extends along a predetermined section of the outer circumferential surface 36.

In the sleeve-shaped fastening element 12, an elastic element 14 is arranged, which is fastened to the fastening element 12. Proceeding from the second end portion 18, in which the spring element 14 is mounted on the inner circumferential surface 24 of the fastening element 12, a cavity 34 surrounds the spring element 14. The cavity 34 is bounded radially by a layer 36 of elastomeric material on the inner circumferential surface 24 and the outer face of the elastomeric element 14. The spring element 14 is designed in such a way that the center axis M of the receiving opening 30 is_ADRelative to the central axis M of the fixing element 12_BShifted by a predetermined shift amount V. In the central axis M of the receiving opening 30_ADWith the central axis M of the fixing element 12_BThe amount of displacement V therebetween refers to the amount of radial displacement. Thus, two central axes M_ADAnd M_BAre offset from each other in the radial direction but extend parallel to each other by a predetermined shift amount V.

The spring element 14 has a radial section 40 by means of which it is connected in the second end section 18 to the inner circumferential surface 24 of the fastening element 12. Starting from the radial section 40, the spring element 14 extends in a substantially conical section 42 to the tubular end section 28 of the receiving section 28₁。

The spring element 14 is connected in the fastening region BB with its radially extending portion 40 to the inner circumferential surface 24 of the sleeve-like fastening element 12 in the second end portion 18. The fastening region BB extends along the inner circumferential surface 24 of the fastening element 12 over a predetermined distance from the axial end face of the fastening element 12. The axial extension of the fixing region BB corresponds substantially to the axial extension of the radial segment 40 of the elastic element 14. The fastening region BB and the receiving opening 30 run along the center axis M of the fastening element 12_BAre arranged offset from each other by an axial displacement amount AV. Axial extension of the fastening region BB and the receptacle in cylindrical configurationThe axial extensions of the ports 30 do not overlap one another. The receiving opening 30 is arranged radially inwardly with respect to the first end portion 16 of the fastening element 12. At the radial segment 40 and the tubular end 28 of the receiving segment 28₁In its section 42, the spring element 14 extends substantially in the form of an oblique truncated cone. Starting from the axial end face of the fastening element 12, an opening 26 in the spring element 14 extends in the form of a truncated cone through the spring element 14 until it merges into a receiving opening 30 of cylindrical design. Central axis M of receiving opening 30_ADAnd the central axis M of the fixing element 12_BAre distributed parallel to each other with a radial shift amount V. In addition to the amount of axial displacement AV between the receiving opening 30 and the fastening area BB, there is a central axis M_BAnd M_ADThe amount of radial shift therebetween.

Between the thin layer 36 of elastic material on the inner circumferential surface 24 of the fixing element 12 and the outer face of the elastic element 14, a cavity 34 extends to a radial section 40 of the elastic element 14 in the second end section 18. The cavity 34, which surrounds the elastic element 14 in sections, also does not have a rotationally symmetrical shape, depending on the shape of the elastic material 14. In addition to the shift amount V, this is also clear in the following manner: in the sectional view according to fig. 4, in the center axis M of the fastening element 12_BThe distance between inner circumferential surface 24 and the wall of receiving opening 30 in the lower region is greater than central axis M of fastening element 12_BThe distance of the wall of the receiving opening 30 from the inner circumferential surface 24 in the upper region. At the end of the cavity 34 or at the transition of the truncated-cone-shaped section 42 into the radial section 40 of the spring element 14, a recess 44 rounded in cross section is formed in the axial direction, which radially surrounds the truncated-cone-shaped section 42. The recess 44 forms an undercut in the resilient element 14. The recess 44 assists in the deflexibility of the resilient member 14 relative to the fixed member 12.

Tubular end section 28 for receiving section 28₁Projecting axially at a predetermined distance beyond the axial end face of the end section 16 of the fixing element 12. End face 28 of end segment 28₂Extending parallel to the axial end faces of the end sections 16. The transition edge between the chamfer 32 and the cylindrical receiving opening 30 in the sectional view according to fig. 4 is essentially at the endThe axial end edges of the segments 16 are congruent. End face 28 of receiving segment 28₂With a predetermined amount of axial displacement AV_sBSpaced from the fixed area BB. The predetermined amount of axial displacement being at the end face 28 of the receiving section 28₂And the radial segment 40 of the resilient element 14.

The layer 36 of elastic material extends from the radial portion 40 along the inner circumferential surface 24 of the fixing element 12. In the region of the bulge 20 on the first end section 16, an inwardly bulging 46 is formed on the inner circumferential surface 24. In the region of the inward bulge 46, the layer 36 is correspondingly thicker, so that the layer 36 has a regular surface.

Fig. 5 and 6 show perspective views of a support element 110 according to a second embodiment of the invention.

The support element 110 has a sleeve-like fastening element 12 and an elastic element 14. The spring element 14 is arranged in the fastening element 12 and is connected to the fastening element 12 in a fastening region BB. The spring element 14 is connected to its inner circumferential surface 24 in the second end section 18 of the fastening element 12. A stop element 22 is arranged on the outer circumferential surface 38 of the fastening element 12, which serves to position the support element 110 in its predetermined position on a holder (not shown). The inner circumferential surface 24 of the fixation element 12 is coated with a layer 36 of an elastic material. Between the layer 36 and the outer face of the elastic element 14, the cavity 34 extends to the second end section 18, in which the inner circumferential surface 24 of the fixing element 12 is connected to the elastic element 14.

Fig. 7 shows a perspective view of a support element 110 according to a variant of embodiment of the second embodiment.

According to this embodiment variant, no stop element 22 is provided on the fastening element 12. Furthermore, the fastening element 12 has radially extending segments which extend from the end of the fastening element 12 which is of cylindrical design.
