Description

Arrangement for connecting suspension components and Radträqer for

motor vehicles

The invention relates to an arrangement for connecting suspension components, in particular screw, between a structure made of a fiber-plastic composite (FKV) and a metallic, in particular designed as a traction element load introduction element. The invention further relates to a wheel carrier for motor vehicles with an at least double-walled structure of a fiber-plastic Verbu nd.

Under the designation fiber-plastic composite, abbreviated FKV, become

Plastic materials understood which from a textile of long or

Endlosfasern, for example made of glass or carbon and on the other hand from a matrix component connecting the fibers, z. B. consist of a resin. Instead of the term fiber-plastic composite is in the literature and the

Description Fiber-reinforced plastic, abbreviated FVK, commonly used. Such plastic materials are characterized by a relatively low weight with high strength and are increasingly used in the automotive industry. The problem arises, the FKV structure with other components, eg. B.

Load introduction elements made of metallic materials to combine so that the different material properties of plastic and metal is sufficiently taken into account.

From DE 10 2007 053 120 A1 a wheel carrier for motor vehicles was known, whose structure consists of a fiber composite material and several

Has load introduction elements. Under load introduction element can be understood the support of a shock absorber or the attachment of a spherical plain bearing for a suspension arm. The basic structure of the known wheel carrier is trough-shaped and consists of a single deformed

Plastic wall. For the attachment of load introduction elements, z. B. for suspension arms are preferably recesses in the plastic wall

intended. It is an object of the present invention, plastic structures, in particular made of a fiber-plastic composite material suitable with a

Load introduction element, in particular to be reliably connected from a metallic material.

Moreover, it is an object of the invention to connect a wheel carrier with a structure made of a fiber-plastic composite with a metallic load introduction element.

The objects of the invention are characterized by the features of the independent

Claims solved. Advantageous embodiments will be apparent from the

Dependent claims.

According to the invention, an arrangement results for the connection of

Chassis components between a structure made of a fiber-plastic composite (FKV) and a metallic, in particular designed as a traction element,

Load introduction element, the structure multi-walled, in particular

double-walled, is formed and has a first wall and at a distance from the first arranged at least another wall, wherein the first and the further wall each having coaxially arranged recesses. The arrangement is characterized in that between the first and the further wall, a spacer having a through hole is arranged, wherein the

Load introduction element at least one recess and the through hole of the spacer passes through. The through hole can be made as a machined or erosive bore or as a highly accurate fit.

The load introduction element is associated with a holding member, wherein the

Load introduction element and the holding member by a connecting portion, in particular form, force, and / or materially connected to each other, and wherein the connecting portion and / or the holding member substantially pass through the first and / or the at least another second wall. The connecting portion may be designed as a threaded portion. In that case, the

Load introduction element and the holding member internal or external thread, so that these components can be screwed together. According to a first aspect of the invention, an arrangement for connecting chassis components with a load introduction element and a holding member is thus provided, wherein the load introduction element and the holding member are connected to each other via a connecting portion, which is arranged substantially within the outer contours of the at least double-walled structure. On the one hand a space advantage is achieved that the elements of the

Connecting arrangement, in particular the retainer, not substantially beyond the outer contour are also arranged within the multi-walled, in particular double-walled structure. This can be over the adjoining the outer contour of the structure space in favor of other components. Due to the multi-walled structure, comprising a first and an at least further, second spaced-apart wall, there is the advantage that initiated via the load introduction element into the structure moments and / or tensile or compressive forces are absorbed by a pair of forces, wherein in one Wall primarily tensile stresses and in another or the other wall

primarily compressive stresses occur. The particularly damaging to the plastic structure bending stresses are thus avoided. Preferably, the load introduction element is designed as a tension member. In the structure of a fiber-plastic composite through holes are also provided for reaching through the holding member or the load introduction element. These can be machined. But it is also possible that the through holes were produced in the production of the fiber-plastic composite for the intended chassis component by widening or Aufdornung the fiber material. By this is meant that the fibrous web at the points provided for a through-hole prior to feeding the plastic (for example a resin) through a conical object, e.g. Thorn or cone, is widened. This prevents that the fibers are interrupted in the region of the through hole, as is the case with a machined through hole.

According to a preferred embodiment, the holding member is formed as a threaded sleeve, which preferably, indirectly or directly, is supported against the first wall and protrudes with its threaded portion in the intermediate space between the first and the second wall. This results in a relatively flat Outside contour for the first wall. The connecting portion is preferably designed positively as a threaded / screw connection. Alternatively, a cohesive connection in the form of an adhesive connection or welded connection can be selected.

According to a further preferred embodiment, the holding member is formed as a recessed nut, d. H. the nut is countersunk against the outer contour of the first wall in the intermediate space between the first and the at least second wall. The sunken nut is supported indirectly against the first wall.

According to a further preferred embodiment, the holding member is designed as a recessed cylinder head screw, preferably with a hexagon socket or hexalobular, with the cylinder head screw indirectly supported relative to the first wall. Again, this results in a flat outer contour.

According to a further preferred embodiment, the load introduction element is designed as a ball pin, wherein the ball head is arranged outside the outer contour of the second wall and is part of a pivotable ball joint, via which transverse forces in the at least double-walled structure can be introduced.

According to a further preferred embodiment, the ball stud has a substantially conical shaft or a cylindrical shaft. This results in the possibility of a play-free, non-positive or frictional recording in a corresponding conical sleeve.

According to a further preferred embodiment, the particular, conical shaft (outer cone) of the ball stud in the recess, in particular the inner cone, a conical sleeve is arranged, where it is frictionally held under tensile load. On the ball pin from the outside acting radial and axial forces are thus introduced without play on the conical sleeve in the at least double-walled structure. According to a further preferred embodiment, the holding member, in particular the threaded sleeve or the countersunk nut on an internal thread, while the ball pin end has an external thread. Inside and

External threads form the connecting, in particular threaded portion arranged within the double-walled structure. Thus, a space gain is achieved in the direction of stress.

According to a further preferred embodiment, in the load introduction element, in particular tension member, preferably in the ball pivot either in the end face of the ball head or in the end face of the thread, a blind hole with a

Polygon cross section arranged. Preferably, the blind hole has a

Hexagon socket or a hexalobular, so that by means of a suitable mounting tool, a torque can be exerted on the tension member for the purpose of screwing to the holding member. This results in a space gain in the direction of stress, d. H. in the longitudinal direction of the ball stud.

According to a further preferred embodiment, the holding member,

in particular the threaded sleeve, a collar, which is supported directly or indirectly against the first wall. The resulting from the ball stud

Traction is thus transmitted through the collar of the threaded sleeve on the outer surface of the first wall.

According to a further preferred embodiment, the recessed nut is indirectly supported via a collar sleeve relative to the first wall, d. H. the recessed nut rests on the collar sleeve and the collar sleeve is supported against the first wall, which also achieves a flat design. The countersunk nut can be tightened or loosened with a socket wrench.

According to a further preferred embodiment, the as recessed

Cylinder head screw trained holding member an external thread and designed as a ball pin tension member has an internal thread, which with the

Outside thread of the cylinder head screw inside the double-walled structure arranged threaded portion forms. The head of the cylinder head bolt is almost completely recessed against the outer contour of the first wall.

According to another preferred embodiment, the recessed

Cylinder head bolt over a collar sleeve opposite the first wall, d. H.

indirectly supported. The cylinder head bolt is supported against a first collar of the collar sleeve and the collar sleeve is supported via a second collar relative to the first wall. This also achieves a flat design, which also requires little space in the radial direction.

According to a further preferred embodiment, a first disc with a micro-toothed surface is arranged between the collar of the holding member designed as a threaded sleeve and the first wall, which presses into the first wall, which has a softer surface. Thus, the advantage of increasing the coefficient of friction between metal and plastic is achieved. Microdipped surfaces are known per se, for. B. "Design 2013", page 62 - 65. (H. Schürmann, H. Elter: Contribution to the design of screw joints in laminates of fiber-plastic composites.) In the case of the preferred screw the coefficient of friction increases the frictional force (parallel to the wall surface), so that with the same biasing force of the tension member, a larger pair of forces for receiving the externally introduced load moment is available.

According to a further preferred embodiment, the conical sleeve has a collar, which is supported relative to the second wall. About the Federation of

Konus sleeve thus axial forces of the ball pin, mainly resulting from the tension with the retainer, transferred to the second wall.

According to a further preferred embodiment, between the collar of the conical sleeve and the second wall is a second disc with micro-teeth

Surface arranged. This results in an increase in the coefficient of friction and the resulting friction force on the outer surface of the second wall, so that the load torque counteracts a larger force pair. Overall, this is about the ball stud in the more, especially double-walled, structure introduced load moment transmitted on the one hand via frictional engagement and on the other hand via positive locking, wherein the positive engagement acts as a kind of reserve or security when the frictional engagement fails (transition from the static friction on

Sliding friction).

According to a further preferred embodiment, the first or the second disc with a micro-toothed surface has projecting pins which engage positively in corresponding openings in the first and / or second wall and / or the spacer. Thus, the proportion of the positive connection in the load introduction are increased and reduces the bearing pressure of the claimed surfaces; a higher load can be absorbed by the FRP structure.

According to a further preferred embodiment, the holding member, in particular the collar of the threaded sleeve surfaces or openings, on the periphery or in the openings or recesses of an assembly tool can be form-fitting recognized, the assembly tool, in particular exclusively, for mounting in the application of Preload the

Screw connection is used.

According to a second aspect of the invention are in a wheel carrier for

Motor vehicles in fiber-plastic composite construction load elements by means of the inventive arrangement for connecting chassis components, in particular a screw fastened. It is about

preferably to a wheel according to the earlier application of the applicant with the official file number 10 2013 209 987.8, the contents of which is fully included in the disclosure of the present application. The wheel carrier of the earlier application has a first formed as an inner shell and at least another second formed as an outer shell wall, so that there is a multi, especially double-walled, structure, at which by means of

Arrangement for connecting suspension components, in particular

Screw connection, load introduction elements, preferably metallic ball studs can be attached. On the ball studs preferably grip or Tie rods, which introduce lateral forces or moments in the structure of the wheel carrier. Due to the compound of the invention, in particular

Screw connection, while the FKV structure of the wheel carrier is claimed relatively low and minimally deformed.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below, which may result from the description and / or the drawing further features and / or advantages. Show it

1 shows a screw connection 1 according to the invention between a

double-walled structure, comprising a first wall 2 and a second wall 3, and a load introduction element 4, formed as a metallic ball stud 4. The first wall 2 and the second wall 3 of the double-walled structure consist of a fiber-plastic composite (FKV), which is constructed of long or continuous fibers and a matrix component of a synthetic resin. The fibers form a textile, z. B. a fabric with a stress-oriented orientation of the fibers. Such FKV structures are known from the prior art, in some cases, the term fiber composite plastic (FRP) is in use. The only partially illustrated double-walled structure 2, 3 is part of a larger component, in which forces are introduced from another component, not shown, via the load introduction element 4. The ball stud 4 has a

Longitudinal axis a, a ball head 4a, a conical shaft 4b and a

External thread 4c on. The first wall 2 has a recess 2a and the second Wall 3 has a recess 3a. Between the first wall 2 and the second wall 3, a spacer 5 is arranged, which has a coaxial with the longitudinal axis a arranged through hole 5a. In the recess 2a of the first wall 2, a threaded sleeve 6 is inserted, which has an internal thread 6a and a collar 6b. The external thread 4 c of the ball stud 4 is connected to the

Screwed internal thread 6a of the threaded sleeve 6 and forms a

Threaded portion 7. In the recess 3a of the second wall 3, a tapered sleeve 8 is inserted, which protrudes with its cylindrical shank into the through hole 5a of the spacer 5. The conical sleeve 8 has an inner cone 8a and a collar 8b. The conical shaft 4b or outer cone 4b sits without play in the inner cone 8a and is held there by frictional engagement. The first wall 2 has an outer surface 2b, also called outer contour 2b, and the second wall 3 has an outer surface 3b, also called outer contour 3b. Immediately on the outer surface 2b, a first disc 9 is arranged with a micro-toothed surface 9a, while on the outer surface 3b of the second wall 3a, a second disc 10 is arranged with a micro-toothed surface 10a. The first and second disks 9, 10 are metal disks whose micro-toothed surfaces 9a, 10a dig into the plastic surfaces 2b, 3b and thus increase the coefficient of friction. This effect is known from the reference cited "Construction 2013", page 62 - 66. In the collar 6b, which rests on the first disc 9, are distributed on the circumference, holes 6c, in which pin 1 1 a of a

Engage mounting tool 1 1. In the end face of the ball stud 4 is a blind hole 4d arranged with a polygonal cross-section, hexagon socket or hexalobular, in which a corresponding mounting tool (Allen key) can be used.

To produce a load-bearing screw connection, the ball pin 4 and the rotatably arranged threaded sleeve 6 are screwed and clamped together via the threaded section 7, the tightening torque being introduced via the assembly tool 11 and the holding torque via the hexagon socket 4d. Via the prestressing or tensile force thus generated in the direction of the longitudinal axis a, the microdipped surfaces 9a, 10a are pressed into the outer surfaces 2b, 3b. The first wall 2 is opposite the second wall 3 via the spacer 5, which can be made of metal or plastic, supported. Via the ball head 4a, mainly transverse forces, ie substantially perpendicular to the longitudinal axis a, are introduced into the FRP structure 2, 3, ie the structure 2, 3 is loaded by a moment. This loading moment is absorbed by a pair of friction forces which acts in the planes of the outer surfaces 2b, 3b. This results in a relatively small load for the double-walled structure 2, 3. As can be seen from the drawing, the threaded portion 7 is substantially, that is arranged for the most part within the outer contour 2b, ie only a relatively small portion of the threaded portion 7 and the threaded sleeve. 6 projects beyond the outer contour 2b. The attachment of the load introduction element 4 is thus largely within the double-walled structure 2, 3, ie their

Outer contours 2b, 3b housed.

The ball pin 104 has at its end remote from the ball head 104a an external thread 104c, which is screwed to the internal thread 106a of the threaded sleeve 106. In the collar 106b of the threaded sleeve 106 engages - analogous to the first embodiment - a mounting tool 1 1 1, which is removed after installation of the screw. Of the

Thread portion 107, which connects the ball pin 104 with the threaded sleeve 106, projects slightly beyond the outer surface 102b of the first wall 102. The introduced via the ball head 104a load moment is transmitted frictionally and positively in this screw 101, the

Frictional forces in the plane of the outer surfaces 102b, 103b act and the

Positive fit over the circumference of the threaded sleeve 106 in the recess 102 a and the cylindrical shaft 104b of the ball stud 104 in the recess 103a is effective.

The ball stud 204 has a blind hole on the front side with a hexagon socket or hexagon socket 204d for the use of a turning tool. The conical shaft 204b of the ball stud 204 is seated in the inner cone of the conical sleeve 208, which rests with its collar 208b on the outer surface 203b of the second wall 203. The ball stud 204 is clamped over the countersunk nut 206, wherein the bias on the collar sleeve 212 on the outer surface 202b of the first wall

202 supported. The load torque introduced via the ball head 204a is also frictionally and positively locked to the FKV structure 202 in this embodiment as well.
