    Steering column for a motor vehicle and method for producing a steering column
    The present invention relates to a method for producing components for a steering column assembly according to the preamble of claim 1 or 2 as well as such a steering column assembly for a motor vehicle according to the preamble of claim 5.
    The steering column of a motor vehicle assumes the storage of the upper steering line, consisting of a single or multi-part shaft with interfaces to the steering wheel and steering intermediate shaft. The steering intermediate shaft is coupled to the steering column and establishes the connection to the steering gear. Furthermore, the steering column allows the positioning of the steering wheel relative to the driver.
    DE 10 2005 034 952 B3, for example, discloses a steering column which is adjustable in height and inclination. A steering shaft is rotatably mounted in a control part, which is also referred to as a shell unit, casing pipe or steering shaft bearing unit. The jacket unit is held in a holding part and the holding part is mounted in a retaining clip which can be fastened to a vehicle body. To adapt the position of the steering spindle, or a steering wheel to be attached thereto, a clamping system is provided which is adjustable between an open position and a closed position with a control lever. In the open position of the clamping system, the shell unit can be moved in its longitudinal direction relative to the holding part and at the same time 130086AT-2013008880 / LE / 20.06.13 20/06/2013 15:58 2/28 R143 P.005 / 029 FROH +48 541 3357861 (THU) JUN 20 2013 15: 58 / ST. 15: 54 / No. 8400108324 P 6 ······ «> ..,. * ............ ···· · · · · ··· ·. , ; ··; ···· ··· · «... - 2 -
    Holding part to be pivoted in its inclination about a pivot axis relative to the retaining clip. In the closed position of the clamping system, the steering shaft is fixed relative to the body-mounted retaining clip. Such steering columns and clamping systems are known in the prior art in various designs.
    In addition, the steering column makes a significant contribution to driving safety. In the case of an accident, when the driver hits the airbag, the steering column gives way in a defined manner.
    A conflict of interest in the technical design of the steering column is the requirement for installation space, rigidity and weight. At present, generic steering columns and their components are preferably made of steel,
    Sheet metal, aluminum or magnesium cast.
    However, it is desirable to reduce the weight of the steering column and its components while maintaining at least equal strength and stiffness properties. This reduction would lead to a favorable effect on fuel consumption and to improve the driving dynamics of motor vehicles and to increase the range of electric vehicles.
    Minimizing dead weight while maintaining rigidity and strength can be achieved through the use of specific materials such as fiber composites.
    Fiber composites consist of reinforcing fibers embedded in a matrix. In general, the specific stiffness of a fiber composite or a hybrid material of metal and fiber composite material is higher than that of metal alone. The higher quality properties are achieved only by the interaction of both components. There are a variety of manufacturing processes in which the pre-impregnated with a matrix material fibers are processed. One of the established manufacturing processes is the fiber winding process. In the filament winding process, continuous fiber strands (rovings) are wound onto a winding core in a continuous process. In doing so, the 130086AT-2013008880 / LE / 20-06.13 20/06/2013 15:58 3/28 R143 P.006 / 029 FROM +48 541 3357851 (THU) JUN 20 2013 15: 53 / ST. 15: 54 / No. 8400109324 P 7 • ·· ·. ·· ·. ... .... ... .. · - 3 -
    Fibers are often soaked in the same operation with a matrix resin and wet impregnated or unimpregnated fibers are processed, which are impregnated after the winding process with a resin injection process. The fiber winding process is characterized by a high laminate quality and a high accuracy in the fiber resin content and in the fiber orientation with a high degree of automation and high efficiency.
    In EP 1 268 164 Bl a truss-like component made of fiber-reinforced plastic and a method for producing the same are disclosed. The production of the truss-like component takes place depending on the expected or predetermined load by the fiber winding process. For this purpose, a number of winding coils are provided on a winding plate around which the preimpregnated fiber is wound. The cavities between the resulting AuBengurtteilen and the intermediate structure are at least partially filled with a filler. The filler supports the pressure-loaded portions of the truss-like intermediate structure and prevents uncontrolled buckling when exceeding the load for which they are designed. Truss-like structures are characterized by their high degree of stability. It is intended to use these elements as carriers e.g. in a vehicle chassis, wherein the filling material u.a. the energy absorption in the event of a crash favors. Due to the predetermined truss-like structure, the shape and the course of the reinforcement, the support member can not be designed individually. Although the gain of the load can be adjusted by a different number of fibers, a specific design along lines of force of a component is not possible.
    It is therefore an object of the present invention to provide individually molded components, in particular for a steering column assembly and its components of a motor vehicle in fiber technology, which have high strength properties and stiffness properties and low weight. Furthermore, a design for such components is to be created, which allows a defined design of the components. 130086AT-2013008880 / LE / 20.06.13 20/06/2013 15:59 4/28 R143 P.007 / 029 FROM +48 541 3857861 (THU) JUN 20 2013 15: 57 / ST. 15! 54 / No. 8400109324 P 8

    This object is achieved by a method having the features of claim 1 or 2 and by a steering column assembly and its components having the features of claim 5. In the dependent claims advantageous developments of the invention are shown.
    Accordingly, there is provided a method of manufacturing a steering column assembly and its components, particularly for motor vehicles, comprising the steps of: a) winding fibers along predetermined paths about at least one reel spool of a reel hub; b) introducing a hardenable resin into the fibers; c) curing the resin and forming the fiber composite component; d) removal of the at least one winding spool inwards into the winding core; e) removal of the winding core and release of the fiber composite component; f) Assembly of the steering column assembly with installation of the fiber composite component in the steering column.
    In a preferred embodiment, after step a), the wrapping of the wound winding core into a tool mold takes place and, after step c), the removal of the fiber composite component including the winding core from the tool mold. In step b), the resin is then introduced into the mold.
    In an alternative embodiment, the fibers are soaked with a hardenable resin before winding, so that the subsequent introduction of the curable resin can also be omitted. Correspondingly, there is a slightly different sequence, which leads to the same result. In this alternative embodiment, the method comprises the steps of: a) winding fibers along predetermined paths around at least one reel spool of a winding core, the fibers being impregnated with a thermosetting resin; b) curing the resin and forming the fiber composite component; 130086AT-2013008880 / LE / 20.06.13 20/06/2013 15:59 5/28 R143 P.008 / 029 FROH +48 541 3357861 (THU) JUN 20 2013 15: 57 / ST. 15: 54 / No. 8400108324 P 8 * * ·· ···· ·· a "• ::::::::: ::::. ·: ··· ·· ·· ··· · ♦ ·· ··· - 5 - c) removal of the at least one winding spool inwards into the winding core; d) removal of the winding core and release of the fiber composite component; e) Assembly of the steering column assembly with installation of the fiber composite component in the steering column.
    In a preferred embodiment, after the step a), the wrapping of the wound winding core into a tool mold takes place and, after the step c), the removal of the fiber composite component including the winding core from the tool mold
    In the alternative embodiment as well, a hardenable resin may additionally be introduced into the tool mold before the step of curing the resin takes place.
    Particularly preferred is the application of the method for a steering column assembly in which the jacket tube, which can be generally referred to as a steering spindle bearing unit or shell unit, slidably guided in a pivot lever along the longitudinal axis of the steering shaft, and wherein the pivot lever pivotally mounted about a pivot axis in the console is. As a result, a height and length adjustable steering column is shown in a lightweight construction.
    Fiber strands are formed by the winding of the fibers.
    Preferably, one or more functional elements are positioned at predefined locations on the winding core in a method step prior to winding in order to be connected by the subsequent process steps with the fibers in order to form a one-piece component with the fiber composite part. The functional elements remain in the component, they form interfaces and functional surfaces that can not be efficiently wound.
    In addition, it can preferably be provided that in an operation before winding an auxiliary material is applied to the winding core, which keeps the fibers in shape and position until they are fixed by curing the resin. This ancillary material may be a woven or nonwoven fabric which may be bonded to the fabric 130086AT-2013008880 / LE / 20.06.13 20/06/2013 15:59 6/28 R143 P.009 / 029 FROM +49 541 3957961 (THU) JUN 20 2013 15: 53 / ST. 15! 54 / No.9400109324 P 10 • ·· • 9 · · · · O •••••••••••••••••••••••••••••• •••••••••••• · · ·· 9 · · · · · · · · · · · · «··· ·······························
    Matrix also forms a fiber composite and serves to receive base loads, for the introduction of loads or as a force-free structure.
    Furthermore, a steering column arrangement is provided for a motor vehicle, with a steering shaft rotatably mounted in a shell unit about a longitudinal axis, wherein the jacket tube is mounted in a console which is adapted to connect the shell unit with a body of the motor vehicle, the at least one component made of fiber-reinforced composite, which is manufactured according to one of the previously described method.
    Particularly preferred is a steering column assembly in which the jacket tube, which can be generally referred to as a steering spindle bearing unit or shell unit, slidably guided in a pivot lever along the longitudinal axis of the steering shaft and the pivot lever is pivotally mounted about a pivot axis in the console, the console and / or the pivot lever and / or the casing tube made of fiber-reinforced composite material according to the method of the invention is formed. As a result, a height and length adjustable steering column is shown in a lightweight construction.
    The component is preferably located in the power flow of the steering column between the steering shaft and the body, as given in particular for the console, the pivot lever and the jacket tube, and has along the power flow fiber reinforced plastic, in which the fibers are wound.
    According to a preferred embodiment, the fiber-reinforced plastic is a combination of different fiber structures with rectified fibers.
    Preferably, the component has fiber strands whose fibers are aligned along a main force flow direction between a selection of two functional elements with which the steering column component is supported in a substantially straight line and substantially parallel to each other, wherein between such fiber strands formed space regions are formed where no fibers and no plastic are arranged. In other words, the fibers are 130086AT-2013008880 / LE / 20.06.13 20/06/2013 16:00 7/28 R143 P.010 / 029 FROH +49 541 9357961
    (THU) JUN 20 2013 15! 59 / ST. 15: 54 / No. 8400109324 P 11 • * - 7 - summarized as fiber strands, as aligned parallel to each other in a framework support structure. The restriction "essentially " refers to permissible deviations, from straightness or parallelism, in the range of a few angular degrees, certainly less than 5 or preferably less than 3 angular degrees.
    For the representation of components of a steering column, in particular the console, the pivot lever or the steering shaft bearing unit, it is particularly preferable to form three-dimensional fiber strands, wherein at least one of the fiber strands is arranged at an angle to the plane which is spanned by at least two other fiber strands. Accordingly, at least one functional element is preferably arranged in another plane, in comparison to the plane defined by the at least two fiber strands.
    Furthermore, individual fiber strands can be formed continuously differentiable bent, within the fiber strand, the individual fibers are aligned substantially parallel to each other. This is particularly advantageous when the power flow has to be conducted over different levels, in particular must be conducted to a bend or edge and a functional element arranged in the power flow is not provided on the component. Due to the constantly differentiable lines, the force transfer takes place with reduced risk of buckling or notch effect.
    Preferably, the component is manufactured using a winding core, which is separated from the component before assembly of the component in the steering column assembly and is not included in the steering column assembly. This winding core has an opposite contour to the course of the fiber strands. In particular, the formation of continuously differentiable bent fiber strands is easily possible. The steering column according to the invention has a very high rigidity and robustness, although only a few fiber strands with large gaps serve to form the component of the steering column. This is possible because the loads are taken either along the fiber strands or across the fiber strands via adjacent components of the steering column. Accordingly, the component itself does not have to absorb the loads in all directions or even the load must be subjected to the load. 130086AT-2013006880 / LE / 20.06-13 20/06/2013 16:00 8/28: R143 P.011 / 029 FROH +48 541 8357861 (THU ) JUN 20 2013 15: 58 / ST. 15: 54 / No. 8400108324 P 12 »♦♦ ♦ ·« · · · t «• · · · · ♦ · · · · < ············

    The intended functional elements of the component are preferably selected from the group comprising fastening elements, guides, movement limitations, bearings and holders for Kabeibäume.
    In a further embodiment, the functional elements are sheet metal tabs with openings, bores or recesses. Also sintered moldings or castings can be integrated as functional elements of the components. Furthermore, other shaped parts made of different metals or plastics can also be used as functional elements. The inventive method is particularly flexible here.

    11: a spatial representation of an inventive
    A steering column assembly.
    FIG. 1 shows a generic steering column 1 with a steering spindle 2, a jacket tube 3, a pivoting lever 4, a console 5 and a steering shaft part 6. The steering shaft 2 is rotatably mounted in the casing tube 3. The jacket tube 3 is guided in the pivot lever 4 along the longitudinal axis of the steering shaft 2 slidably. The pivot lever 4 is pivotally mounted about a pivot axis in the console 5. The console 5 can be attached to attachment points 7 on the body, not shown. The introduced by a driver via a steering wheel in the steering shaft 2 rotational movement is introduced via a universal joint 8 and other steering shaft parts 6 in the steering gear, not shown. The steering column 1 can be adjusted to increase the comfort of the driver in their height and their length. For this purpose, a fixing mechanism is provided which comprises a tensioning apparatus. The tensioning device has a clamping bolt 9, a tensioning lever 10 and a cam mechanism, not shown.
    By rotation of the clamping lever 10, the two cams of the cam mechanism are rotated against each other and the side cheeks of the console 5 contracted, whereby a frictional clamping of the side walls of the bracket 5 with the side surfaces of the pivot lever 4 and wiederum done with the side surfaces of the casing tube 3. Such steering columns are known in the art, so that is dispensed with an accurate representation. Alternatively, for example, the bearing of the steering shaft 2 in a non-tubular steering spindle bearing unit, which can also be referred to as a shell unit done. Likewise, the fixation of the steering spindle bearing unit or the casing tube 3 relative to the console by means of a positive connection, for example, a toothing can be shown. Such steering columns are for example also included in the invention.
    FIG. 2 shows a winding core 11 of a console 55 according to the invention with a multiplicity of winding coils 12, 121 and functional elements 13. Before the winding process, the functional elements 13 on the winding core 11 are: 130086AT-2013008880 / LE / 20.06.13 20/06/2013 16: 01 10 / 28R143 P.013 / 029 FROM +48 541 3357861 (THU) JUN 20 2013 15: 58 / ST. 15: 54 / No. 8400108324 P 14 ♦ M ·· 4 «• ·« • ··· • * ·· ♦ ··· «·· <m · · · · ·«. • · · · · · * * * * · · · · · · · · · · ·
    * ♦·· 4M - 10 - positioned and wrapped during the winding process together with the winding core 11 along the winding spools 12, 121. For the purposes of the invention, the winding bobbins can not be formed only by simple cylindrical coils 12. Each tooling 121 around which the rovings are wound is termed "reel spool". subsumed. After completion of the winding process, the winding core 11 is removed, the functional elements 13, however, remain in the component, they form interfaces and functional surfaces that can not be efficiently wound. Such functional elements include, for example, fasteners or bearings.
    FIG. 3 schematically shows the method according to the invention, which is preferably used for producing the components of a steering column made of fiber-reinforced plastic. In the example, the representation of the console 55 is illustrated. However, it is also possible to form the jacket tube or another steering spindle bearing unit or the slide, if present, or another force-transmitting component with this technology. A biased fiber 14 is drawn from a supply spool 15 and passed through an impregnation unit 16. The impregnation unit 16 can be designed as a dip impregnation device or, as shown, for example, as a roll impregnation device. The impregnated fiber 14 is deposited to form the fiber strands 141, 142 by means of a guide unit 17, which is connected to a computer-controlled winding machine, on a synchronized with the guide unit 17 winding core 11 a console. In the example, it can be seen that the winding operation takes place in three dimensions, that is, the fibers are not only wound in one plane, but so that a three-dimensional fiber strand structure is formed. This winding operation preferably takes place without interruption, so that all the fiber strands 141, 142 are formed by a single continuous fiber 14.
    In the figure 4, the winding core 11 is shown with the functional elements 13 in the wrapped state. The impregnated fiber withdrawn from the supply reel as Rovlng is deposited on the reel spools 12, 121 and around the functional elements 13 according to a predetermined winding plan. The winding plan is determined according to the component geometry. 130086AT-2013008880 / LE / 20.06.13 20/06/2013 16:01 11 / 28R143 P.014 / 029 FROH +48 541 3357881 (THU) JUN 20 2013 16: OO / ST. 15: 54 / No. 8400108324 P 15 • 4 • · · • · ♦ ·· · · · · * • * · «

    Design of the winding plan, the power flow directions are analyzed in the console and the targeted storage of fibers 14 in the direction of force flow to form the fiber strands 141, 142, 143, the strength properties and stiffness properties of the material are optimally utilized. This is done by adjusting the fiber volume content, fiber orientation and fiber number according to the force flow. In addition, the weight of the console is reduced by the targeted storage of the fibers. For the production of the console at least one winding circulation is performed.
    If several winding revolutions are performed, then the fibers can cross over in the crossing points from changing directions, whereby the strength is increased across the winding. The winding is performed spatially. For this purpose, the winding core is rotated computer-controlled or stored on a rotation axis, so that the fibers can be guided around the core. In the example (see also FIGS. 8, 9) it can be seen how the winding bobbin 121 does not lie in the plane formed by the fiber strands 141 or fiber strands 143. Accordingly, a strand of fibers 142 is formed during wrapping, which protrudes from the plane formed by the fiber strands 141 or the fiber strands 143.
    In the winding plan, it should be taken into account that the fibers are guided straight as long as possible before the winding direction and thus the orientation of the fibers is changed. This minimizes spots or kinks of the fibers that can cause breakage. Under the same aspect, in a further manufacturing step after winding, the tensioning of the fibers, as shown in FIG. 5, may be provided.
    In FIG. 5, the arrows indicate the tensioning directions of the winding core 11.
    For example, the tension may be generated mechanically by moving the reel spools 12, or by elastic rewind spools that yield during laydown and then return. The tension applied to the fibers biases the fibers to reduce kinks in the fibers. This process increases the strength and rigidity of the fiber composite in the deposit direction. 130086AT-2013Q0888Q / LE / 20.06.13 P.015 / 029 20/06/2013 16:02 12 / 28R143 FROM +48 541 3357861 (THU) JUN 20 2013 18: OO / ST. 15! 54 / No. 8400108324 P 16 · «« · «IM * · ·» · * * · · ··· «· · · * #

    After winding, the matrix of the fiber is cured. For shaping, in the example, the wound winding core 11 is surrounded by a tool mold 18, as shown in FIG. 6 and FIG. The tool mold 18 shown here has two plates 19, which are each attached to one side of the winding core 11 by means of screw or plug connections, the wound part overlapping. The mold 18 presses the preimpregnated fibers between the plates 19 and the winding core 11 in the desired shape. Thus, the cross section of the workpiece and the fiber volume fraction can be influenced. Thereafter, the curing of the workpiece in the mold 18, for example via a heated mold or by introducing the mold 18 in a continuous furnace.
    After curing, the tool mold and the winding core including the winding spools are removed. The winding core is designed so that the winding coils can be removed inwardly into the winding core and then the winding core is released for removal from the cured console.
    The hardened console 55 according to the invention is shown in FIG. 8 and FIG. In addition to the construct made of fiber composite material, formed by the fiber strands 141, 142, 143, the individual wrapped functional elements 13 can be seen. In the example, it can be seen how the component comprises two parallel planes through the fiber strands 141 and 143 aligned parallel to one another and also a fiber strand 142 connecting the two planes.
    FIG. 10, on the other hand, shows the hardened fiber strands 141, 142 and 143 of the console from the preceding figures without functional elements.
    In the figure 11, the steering column assembly according to the invention with fiber composite console 55 is shown. The integrated functional elements 13 serve as bearings 20 for the pivot axis of the pivoting lever 4 and as fastening elements 77 for fastening the console 55 to the body, not shown here, as well as for the guide elements of the fixing system 90. 130086AT-2013006880 / LE / 20.06.13 20 / 06/2013 16:02 13/28 RI 43 P.016 / 029 FROH +40 541 3357061 (THU) JUH 20 2013 16: OO / ST. 15: 54 / No. 6400106324 P 17 - 13 -
    In contrast to generic steering columns, as shown in Figure 1, the steering column assembly of Figure 11 of the invention by the use of fiber composites on a low weight, with sufficient strength and rigidity is achieved or even increased strength and increased rigidity is achieved.
    The reduction in weight leads to a favorable influence on the fuel consumption and to increase the range of electric vehicles. Due to the power flow design and the high strength in the fiber direction, the space can be kept small. Furthermore, the increased stiffness of the console, the natural frequency of the steering column assembly is positively influenced, so that the vibrations on the steering wheel, which are transmitted through the steering column, are significantly minimized to improve the comfort characteristics while driving.
    In another embodiment, not shown here, the pivot lever is made by the method previously described of fiber composite material. All components of the steering column assembly can be wholly or partly made of fiber composite material.
    By choosing the fibers, the material properties can be varied within a wide range. Preferably, carbon fibers, aramid fibers and / or glass fibers are used singly or in combination.
    As previously described, preimpregnated fibers are preferably used. Preimpregnated fibers have a thermoplastic or thermosetting impregnation. The fibers provided with a thermoplastic impregnation can advantageously be processed into a hybrid yarn in combination, for example, with carbon fibers and / or glass fibers. In one embodiment, it is provided that the hybrid yarns are heated during the winding process, so that the thermoplastic fibers melt to form a matrix of the composite even during winding. Thereafter, the shape of the workpiece can be adjusted in a mold by means of pressing. It is also possible to melt the thermoplastic fibers after the winding process in the 130086AT-2013008880 / LE / 20.06.13 20/06/2013 16:02 14 / 28R143 P.017 / 029 FROH +48 541 3357861 (THU) JUN 20 2013 16! 01 / ST.15! 54 / No. 8400108324 P 18 - 14 - an oven or in a heated mold and / or in the thermoplastic injection molding process.
    Another embodiment provides fibers that are not preimpregnated. These fibers are wound as described in the previous embodiments. After the winding process, the tool mold is mounted or placed the workpiece including winding core in a mold and injected the mold with thermoplastic or thermosetting resin and cured the workpiece. All forms of the Resin Transfer Molding (RTM) process are provided for the use of a thermoset matrix. In comparison to pressing, in this case the matrix mass is injected by means of pistons from a mostly heated pre-chamber via distribution channels into the mold, wherein it cures under heat and pressure.
    To remove the hardened console from the tool mold, the plates of the mold are pulled apart and the winding coils are pulled inwards into the mold.
    In a further embodiment, it is provided to insert the mold before or after the addition of resin in an injection molding machine and to overmold or backmold the workpiece for advanced shaping with thermoplastic or thermosetting injection molding.
    Another embodiment provides that the flow of fibers on auxiliary materials, such as plastic fabrics or webs or fabrics, is carried out in a manner commensurate with the flow of force and keeps the fibers in shape and position until they are fixed by a matrix. When using woven and laid, these form with the matrix as well a fiber composite, which serves to take up base loads, the introduction of loads or as a force-free structure.
    The steering column assembly according to the invention has individually molded components in fiber technology with high strength properties and high stiffness properties and low weight. Furthermore, the method according to the invention enables a defined design of such components which is suitable for the flow of force. 130086AT-2013008880 / LC / 20.06.13 20/06/2013 16:03 15/28 R143 P. 018/029 FROM + 4S 541 3357861 (THU) JUN 20 2013 16: 01 / ST, 15: 54 / No.3400108324 P 13 • · ·· MM · «· · · · · · · · · · · · · · · · · · · · · · · ·«
