Description

TECHNICAL FIELD

[0001] The invention relates to a steering column for a motor vehicle, comprising a steering spindle which is held in a rotationally fixed manner about its longitudinal axis in relation to a housing unit, which is connected to a return limiter for limiting the rotation of the steering spindle, which return limiter has a winding core which is connected to the steering spindle, which winding core is arranged in a housing which is connected to the housing unit, and one winding section of an elongate, laterally to its longitudinal extension flexibly deformable band element, which is configured as a closed loop band made of a flat band, which loop band has a band cross section with a certain band width and a comparatively small band thickness. BACKGROUND

[0002] The steering spindle is rotationally fixed in the housing unit which forms the steering column housing. The housing unit is held by a carrier unit which can be connected to the vehicle body and is preferably adjustable in relation thereto. For steering the motor vehicle, a manual steering command is input by the driver turning a steering wheel which is mounted on the driver side in the direction of the steering spindle rear end in the direction of travel, which steering command is converted into a steering angle of the steering wheels of the motor vehicle.

[0003] In conventional steering systems, the steering spindle is mechanically connected to the wheels by a steering transmission, while in steer-by-wire systems the rotation of the steering spindle is detected by means of a rotation sensor with at least one angle sensor and / or torque sensor and converted into an electrical control signal for actuating an electrical steering actuator which generates the steering angle of the steerable wheels. Since there is no mechanical coupling to the wheels in this case, the rotation of the steering spindle is not limited by the mechanical end stop of the wheels when the maximum steering angle is reached. However, in order to avoid excessively sharp turns and also to simulate a realistic steering feel, it is known to limit the maximum possible angle of the steering wheel by means of a return limiter which constitutes a limiting device with an end stop for limiting the maximum possible rotation of the steering spindle.

[0004] A steering column with a return limiter is known, for example, from DE 10 2021 201 640 A1. The return limiter comprises a winding core mounted on the steering spindle, on which, in rotation, a flexible band of a band element is wound. The band element is configured as a closed loop band which is connected in one winding section to a housing which is fixedly connected to the housing unit. If the band is wound to such an extent that it is tensioned between the winding core and the fixing device, an end stop is achieved.

[0005] The fixing device must provide a reliable, tension-resistant fixing of the band element on the housing unit. In particular, slipping of the loop band in the end stop during operation should be avoided.

[0006] A steering column of the type mentioned at the outset is known from EP 4 238 853 A1.

[0007] In view of the above-mentioned problems, it is the task of the present application to provide an improved end stop. SUMMARY

[0008] According to the application, this task is solved by a steering system having the features of claim 1. Advantageous refinements result from the dependent claims.

[0009] In a steering column for a motor vehicle, the steering column comprises a steering spindle which is held in a rotationally fixed manner about its longitudinal axis relative to a housing unit, which is connected to the housing unit, in order to be limited in its rotation, a swivel limiter having a winding core which is connected to the steering spindle, which winding core is arranged in a housing which is connected to the housing unit, and one belt section of an elongate, transversely to its longitudinal extension flexibly deformable belt element, which is configured as a closed loop belt made of a flat belt, which loop belt has a belt cross-section with a certain belt width and a smaller belt thickness relative thereto, is wound on the winding core, it is provided according to the application that the belt element is fixed on the housing by a fixing gap in which one belt section of the belt element is accommodated and held in a tension-proof manner.

[0010] The longitudinal extension direction of the belt element is also referred to in the following as the longitudinal direction of the belt or belt element.

[0011] The fixing gap has an elongate, continuously over its gap length transverse to the longitudinal axis gap course, which has a predetermined passage cross-section transverse to the gap length. One belt section of the belt element, which can also be referred to as a fixing section and which constitutes a partial section of the overall belt length, is arranged within the gap length with its longitudinal extension following the gap course and is fixed in the passage cross-section of the fixing gap in a tension-proof manner in the longitudinal direction. As a result, the belt element is reliably fixed on the housing against tensile loads acting in the longitudinal direction of the belt, i.e. in the circumferential direction of the loop belt, in the end stop of the swivel limiter.

[0012] The fixing gap can be realized with low outlay in terms of construction and manufacturing technology, for example by means of a spacing between assembled parts of the housing or by means of a molded part in a housing part. Here, the gap length, the passage cross-section and the gap course can be simply matched to the belt element. As a result, on the one hand an optimized holding effect of the belt section accommodated in the fixing gap can be achieved, and on the other hand it can be ensured that the free belt element can be deformed without interference during the rotation of the winding core relative to the housing when the steering spindle is rotated in the steering operation.

[0013] Advantageously, the belt element is held in the fixed gap in frictional engagement. In the fixed gap, the belt can be clamped, for example, in its belt thickness direction and is fixed in frictional engagement such that the belt is held in the longitudinal direction in force-fit. Here, the gap width of the fixed gap, measured transversely to the longitudinal extension, can be slightly less than the belt thickness, partially or continuously over the gap length, such that the belt is elastically tensioned or slightly pressed, whereby the frictional engagement holding action can be increased. The frictional engagement can also be produced by the belt being placed loosely into the fixed gap and being pressed frictionally against the wall of the fixed gap by the stress occurring in the end stop.

[0014] The fixed gap can be partially elastically configured or have spring-elastic clamping elements or jaw elements in which a belt section can be elastically fixed.

[0015] It is preferred that the fixed gap has a fixing which cooperates with the belt element. The fixing can be arranged on the inner side which faces away from one another transversely to the gap length, such that it can be contacted from the outside by the belt section accommodated in the fixed gap. For example, the inner side of the fixed gap which lies against the belt can have, for example, friction elements and / or form-fit elements between which the belt element is arranged and which it contacts. The friction elements can have, for example, roughening or a friction-increasing coating which can be configured partially or continuously on the inner side of at least one fixed gap facing the belt element in order to increase the frictional engagement holding action between the fixed gap and the belt element. In addition or alternatively, the fixing can have form-fit elements, for example, protruding teeth, knurling, spikes, etc., which likewise can contact the belt section accommodated in the fixed gap and which can then be elastically pressed into or embedded from the outside into the belt surface, thereby producing a local form-fit which is effective in the longitudinal direction between the surface of the belt element and the fixed gap. Thereby, the strength of the belt is not affected and the holding action in the longitudinal direction is advantageously increased.

[0016] An advantageous embodiment can provide that the stationary gap has retaining protrusions projecting transversely to the longitudinal extent, the belt element being accommodated between the retaining protrusions in a manner that is curved multiple times transversely to its longitudinal extent. A plurality of retaining protrusions can be provided, which each extend over a partial section of the length of the gap, viewed in the direction of the gap. The retaining protrusions project opposite one another from both sides of the passage cross section of the stationary gap. Here, the retaining protrusions on one side can project into the gap between the retaining protrusions on the other side in a manner that retains the gap transversely to the longitudinal extent. Correspondingly, the free passage cross section of the stationary gap does not simply extend in the direction of the gap, but rather at least partially waves back and forth between the retaining protrusions opposite one another, over the length of the gap, transversely to the longitudinal direction. The belt section accommodated in the stationary gap follows the passage cross section and likewise waves back and forth around the retaining protrusions. The belt section is curved in the stationary gap multiple times, depending on the number of retaining protrusions, perpendicular to its longitudinal extent and its width, alternating along and against the normal direction, which is perpendicular to the longitudinal direction and the width of the belt. The belt section that waves transversely to its longitudinal extent and the corresponding wave-shaped passage cross section, between the retaining protrusions projecting alternately from both sides of the stationary gap, produce an effective form fit in the longitudinal extent of the belt element. This form fit can particularly reliably and non-slip- pingly absorb the tensile forces acting in the longitudinal extent of the belt in the end stop between the belt element and the housing.

[0017] A further advantageous embodiment can provide that the stationary gap has at least one longitudinal movement arresting element, in which the belt element is accommodated. The arresting element is arranged in the stationary gap in such a way that the belt section accommodated in the stationary gap winds around the arresting element and, in doing so, produces a form fit or a frictional fit that automatically increases with increasing belt tension between the belt and the longitudinal movement arresting element. As a result, the tensile forces acting in the longitudinal extent of the belt in the end stop between the belt element and the housing can likewise be particularly reliably and non-slip-pingly absorbed.

[0018] The housing can be drum-shaped. The housing can preferably be configured as a hollow cylinder and have a coaxially surrounding outer wall and at least one, preferably two, end walls between which the winding core, the belt element and the fixing device are arranged. A compact and functionally advantageous design can thereby be achieved.

[0019] It can be provided that the stationary gap is configured between an inner part and an outer part of the housing. The outer part can preferably be constituted by the outer wall of the housing, for example by a wall section of a tube-shaped or hollow-cylindrical housing part. The inner part can for example be arranged in the inner chamber of the housing, which is coaxially surrounded by the outer part, at a radial distance from the longitudinal axis of the gap width. The stationary gap is then defined by the inner side of the outer part and the outer side of the inner part. The gap width corresponds to the distance between the inner part and the outer part.

[0020] Alternatively, it is also possible that the outer part and the inner part are mounted on the axial end wall, for example as a protrusion protruding axially from the end wall.

[0021] The stationary gap can extend at least partially in the circumferential direction. Here, the stationary gap can extend arcuately over its gap length, preferably in the circumferential direction around an arc segment coaxial to the longitudinal axis. The stationary gap can be limited radially outward by the inner side of the hollow-cylindrical, tubular outer part. In the interior of the outer part, there can be provided an inner part, preferably arcuate, which extends over a circumferential partial segment and limits the gap width with its outer side radially inward. This arrangement has the advantage that sufficient space can be provided radially between the inner part and the winding core, into which the free belt segment wound into and out of the winding core upon relative rotation between the end stops can be reliably accommodated.

[0022] Advantageously, the steering column is configured as a steer-by-wire steering column. It is preferred here that the steering spindle is drivable in rotation by a feedback actuator.

[0023] In a steer-by-wire steering column, the driver's manual steering instructions are input by the rotation of a steering wheel mounted on the steering spindle, as in conventional mechanical steering. However, the steering spindle is not mechanically connected to the wheels to be steered by a steering transmission, but cooperates with a rotation sensor or a torque sensor, which detects the introduced steering instructions and generates an electrical control signal therefrom and outputs it to a steering regulator, which sets a wheel steering angle corresponding to the steering instruction by means of an electrical regulating drive. Since there is no mechanical coupling, the driver does not receive direct physical feedback from the steering wheels via the steering column in the case of a steer-by-wire system, which, in conventional mechanically coupled steering, is transmitted back to the steering wheel as a reaction torque or return torque depending on the road conditions, vehicle speed, current steering angle and other operating states. It is known to simulate the missing haptic feedback by means of an electric feedback actuator, which can be integrated into the steering column of the vehicle. The feedback actuator has a drive unit, which generates a return torque or feedback torque corresponding to the real reaction torque by means of an electric motor depending on a feedback signal and couples it into the steering spindle. This "force feedback" system gives the driver the impression of real driving conditions as in conventional steering, which makes intuitive reactions easy.

[0024] In a steer-by-wire steering column, it is particularly advantageous to integrate the compact and operationally reliable rotation limiter according to the application.

[0025] An advantageous expansion possibility can be realized in that the housing is arranged coaxially inside the driven wheel. In feedback actuators of the aforementioned type, in order to transmit the torque between the electric motor and the steering shaft and to match the rotational speed, a transmission mechanism, for example a belt transmission, is arranged. This belt transmission comprises a driven wheel, for example a pulley, which is torsionally connected with the steering spindle and which is coupled with the electric motor in a driven manner. It is now advantageous for a compact construction that the driven wheel is embodied hollow and open-sided on one side and that the swivel limiter according to the application is integrated into the cavity of the driven wheel which is torsionally mounted on the steering spindle. This can be done with low outlay in that the housing of the swivel limiter according to the application, which is torsionally connected with the sleeve unit, penetrates through the open side of the driven wheel, projects into the driven wheel and thus at least partially fills the cavity of the driven wheel (without, however, being torsionally connected with the driven wheel). Thus, it is possible in an advantageous manner to save construction space and to construct the system particularly compactly.

[0026] In the last-mentioned embodiment, the housing is torsionally connected with the sleeve unit as described, so that the end stop is supported by the steering column on the vehicle body even in this construction.

[0027] The housing can have a plastic part. This plastic part can preferably be configured as an injection-molded part from a thermoplastic polymer. This has the advantage that mechanical functional elements can be integrated in one piece with low outlay, in particular the fixed gap according to the application is also integrated in one piece with the aforementioned fixing elements, retaining projections, etc.

[0028] Alternatively, the housing can have a metal part, for example a die-cast part.

[0029] It can be provided that the housing has a profiled part on which the fixed gap is configured in one piece. The one-piece configuration of the housing, for example as a plastic injection-molded part or a metal injection-molded part, makes it possible to reasonably manufacture and assemble the swivel limiter, for example on the sleeve unit of the steering column and / or on the feedback actuator.

[0030] The sleeve unit of the steering column is held in a manner known per se by a carrier unit which can be connected on the side with the vehicle body. In order to adjust the steering wheel position, the sleeve unit can be designed to be longitudinally adjustable, for example by means of a sleeve tube arranged in a telescoping manner. In order to adjust the height, the sleeve unit can be adjusted upward and downward transversely to the longitudinal axis relative to the carrier unit. BRIEF DESCRIPTION OF DRAWINGS

[0041] In the different figures, identical parts are always provided with the same reference numerals and are therefore generally also named or mentioned only once each.

[0042] Figure 1 and Figure 2 A steering column 1 according to the application, configured as a steer-by-wire steering column, is shown in its entirety in a three-dimensional view and in a side view.

[0043] The steering column 1 comprises a housing unit 2 having an inner housing 21 in which a steering spindle 3 is supported in a rotatable manner about its longitudinal axis L. The steering spindle 3 has, on its end facing the driver's position, which is located rearward relative to the direction of travel, a fastening section 31 on which a steering wheel, not shown here, for inputting manual steering commands can be mounted.

[0044] The inner housing 21, together with the steering spindle 3, is telescopically, longitudinally adjustable in the direction of the longitudinal axis L, accommodated in the housing unit 2, as indicated by the double arrow. For the longitudinal adjustment, a motorized adjustment drive 4 is arranged between the housing unit 2 and the inner housing 21.

[0045] ​​​​​​On the housing unit 2 is mounted an electric feedback actuator 5, which in Figure 3 is shown in cross section A-A.

[0046] The feedback actuator 5 has an electric motor 51, which is coupled via a belt drive to the steering spindle 3. The belt drive comprises a pulley 52 mounted on the motor shaft, a pulley 53 which is connected to the steering spindle 3 in a torque-proof manner and which is embodied as a hollow pulley open on one side, and a belt 54, preferably a toothed belt, which runs around the pulleys 52 and 53.

[0047] The rotation limiter 6 according to the application is arranged in the hollow space of the pulley 53 and limits the possible rotation of the steering spindle 3 about the longitudinal axis L relative to the housing unit 2.

[0048] The rotation limiter 6 has a housing 61, which is shown separately in Figure 5 and Figure 6 . The housing can be configured integrally, for example as a plastic injection-molded part or a metal die-cast part.

[0049] The housing 61 is configured in the shape of a drum and has a tube segment-shaped, hollow-cylindrical outer wall 62, which constitutes the outer part in the sense of the application and in the mounted state surrounds the longitudinal axis L coaxially. Furthermore, the housing has an inner part 63, which is shaped as a circular arc segment and extends coaxially about the longitudinal axis L over an angular segment of less than 180°.

[0050] The housing 61 is arranged coaxially to the longitudinal axis L and is fixed in a torque-proof manner on the housing unit 2, from which the housing extends into the hollow space of the pulley 53 through the open end side of the pulley.

[0051] Between the radially outer side of the inner part 63 and the radially opposite inner side of the outer wall 62, a circular-arc-shaped fixing gap 64 is configured.

[0052] A cylindrical winding core 60, which is connected to the steering spindle 3 in a torque-proof manner, is arranged coaxially in the housing 61. A belt element 7, which is configured in the form of a continuous and closed loop belt made of a flat, flexible belt, passes through a transverse slit 601 of the winding core 60 transversely to the longitudinal axis L and is thereby fixed in a torque-proof manner. When the steering spindle 3 is rotated, the belt element 7 is wound onto the winding core 60. The belt element 7 is fixed on the housing 61 in the fixing gap 64. The belt element 7 can be wound by rotation of the steering spindle 3 until, after a predetermined number of rotations, the remaining free section of the belt element 7 is tensioned between the winding core 60 and the inlet of the fixing gap 64.

[0053] According to the application, the inner part 63 has retaining projections 65 projecting radially outwards from its outer side into the fixing gap 64. The outer wall 62 has retaining projections 66 projecting radially inwards from its inner side into the fixing gap 64, as can be seen in Figure 4 , Figure 5 and Figure 6 . Thus, the retaining projections 65 and 66 project opposite to each other from both sides of the passage cross-section of the fixing gap 64. The retaining projections are arranged staggered in the circumferential direction, so that the retaining projections 65 project radially into the gaps formed in the circumferential direction between two opposite retaining projections 66.

[0054] The belt element 7 is inserted into the fixing gap 64 in one belt section, wherein the longitudinal extension of the belt follows the course of the fixing gap 64. Here, the belt element 7 is curved radially outwards from the retaining projections 65 between the radially inwards opposite retaining projections 66, so that a wave-shaped crimped course results, which is shown in Figure 4 exaggerated wave height with wavy lines for illustration. Thereby, a form fit and / or (self-locking) frictional fit acting in the longitudinal direction of the belt element is achieved between the housing 61 and the belt element 7, which is indicated in Figure 4 with double arrows. Thereby, the belt element 7 is fixed and secured against tensile loads on the housing 61 of the rotation limiter 6 and thus on the sleeve unit 2.

[0055] Figure 7 An alternative embodiment of the application is shown. Here, the outer side of the inner part 63 and / or the inner side of the outer wall 62 has a friction and / or form fit 71, 72 in the form of a roughness and / or a coating which increases the friction, instead of the retaining projections. Instead of a roughness or a coating, it is also possible to use thin-walled attachments with a correspondingly increased friction coefficient or a rough surface structure, for example with bristles, scales, teeth, barbs, etc., which are applied to the wall, for example with adhesive films, battens, clips, etc., or which can also partially replace the wall, for example with inserts or inlays. The friction and / or form fit can extend over the entire fixing gap 64 or only partially be present at specific locations in the fixing gap 64. By the thereby increased wall friction, a frictional fit acting in the longitudinal direction of the belt element is achieved between the housing 61 and the belt element 7, which is indicated in Figure 4 with double arrows. Thereby, the belt element 7 is again fixed and secured against tensile loads on the housing 61 of the rotation limiter 6 and thus on the sleeve unit 2, similar to the first embodiment described above.

[0056] Figure 8A further alternative embodiment of the application is shown. Here, in the fixed gap 64 there is an additional longitudinal movement arresting element 81, through which the belt element 7 is wound in a wave-like manner. The arresting element 81 has a buckle-like shape and can be realized, for example, by two (or more) pins which are fixed in the housing 61, oriented transversely to the longitudinal direction of the belt and spaced apart from one another approximately corresponding to the belt thickness. As a result, the belt element 7 is forced to proceed in a crimping manner back and forth, which then leads, similarly to the first embodiment described above, to a form fit and / or (self-locking) friction fit and fixes and tensions the belt element 7 against the tensile load, similarly to the first embodiment, on the housing 61 of the swivel limiter 6 and thus on the bellows unit 2.

[0057] In an alternative (not shown in the drawing) variant, the longitudinal movement arresting element 81 can also consist of only a single pin, wherein the belt element 7 is then fixed on the longitudinal movement arresting element 81 by means of a loop belt made by sewing the belt and completely wrapping around the pin. As a result, a form fit acting in the longitudinal direction of the belt element, which is indicated in Figure 4 with double arrows, is again realized between the housing 61 and the belt element 7, and the belt element 7 is again fixed and tensioned against the tensile load on the housing 61 of the swivel limiter 6 and thus on the bellows unit 2.
