Description

The invention relates to a holding arrangement of a Radlenkers for guiding a wheel on a support element for a motor vehicle, in particular for a passenger car, according to the preamble of claim 1.

Such holding arrangements of wheel guides formed for guiding wheels on respective carrier elements for motor vehicles, in particular for passenger cars, are already well known from the general state of the art and in particular from series production of vehicles. In the respective holding arrangement, the respective, also referred to as handlebars or guide arms Radlenker is held by means of a holding device pivotally mounted on the carrier element. As a result, the wheel link allows relative movements between the carrier element and the wheel, in particular in such a way that the wheel can spring in and out relative to the carrier element. With appropriate rebound and rebound movements of the wheel of the Radlenker performs pivotal movements relative to the support member.

Furthermore, the DE 10 2016 224 732 A1 a subframe for a motor vehicle axle for connecting Radführungslenkern. Moreover, from the DE 10 2011 082 768 A1 a composite beam axle for a suspension of a motor vehicle known.

Object of the present invention is to provide a holding arrangement of the type mentioned in such a way that the Radlenker can be aligned relative to the support element particularly precise and very simple.

This object is achieved by a holding arrangement having the features of patent claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

In order to further develop a holding arrangement specified in the preamble of claim 1 such that the example designed as a tie rod Radlenker can be aligned particularly precisely and in a particularly simple manner relative to the support member and thus adjusted, it is inventively provided that the holding device separately from the Radlenker and separately formed from the support member integral component, which is held on the support element.

In addition, the holding device comprises at least one eccentric screw on which the wheel link, in particular pivotable, is mounted. As a result, the Radlenker example, relative to the eccentric screw and pivotable relative to the carrier element, wherein the Radlenker is held by the intermediary of the eccentric screw on the support element. The eccentric screw is rotatable, in particular about an axis of rotation, relative to the carrier element, relative to the integral component and preferably also relative to the Radlenker. In addition, the eccentric screw on the integral component in the radial direction of the eccentric screw, that is, along a direction perpendicular to the axis of rotation extending direction such, in particular directly, supported that the eccentric and the eccentric of the Radlenker by relative to the integral component turning the eccentric screw, that is as a result of relative rotations between the eccentric screw and the integral component relative to the integral component and relative to the carrier element are displaceable.

The eccentric screw has, for example, a collar, which does not run concentrically about the axis of rotation, but runs eccentrically with respect to the axis of rotation or is eccentric. The integral component has, for example, two stops which are spaced apart along a direction perpendicular to the axis of rotation. In this case, the federal government between the attacks is arranged and on the attacks, in particular directly, supported. Now, if the eccentric screw is rotated relative to the integral component and thus relative to the attacks, this results in that the collar is eccentric with respect to the axis of rotation and thereby, that the collar is supported on the stops, to a displacement of the eccentric screw relative to the integral component , in particular in the aforementioned direction, along which the stops are spaced from each other.

The integral component is supported, for example, by two cylindrical shape elements on holes provided in the support element and thus holds the position congruent to a slot. Since the Radlenker is held on the eccentric screw and the eccentric screw on the carrier element, the Radlenker is moved with the eccentric screw relative to the integral component and relative to the support member with. In this way, the Radlenker can be particularly easily and precisely displaced by relative rotation between the eccentric screw and the integral component relative to the support member and thus aligned or positioned. If the wheel link is designed, for example, as a tie rod, the track of the motor vehicle can thereby be easily adjusted.

Since the integral component is formed separately from the carrier element and separately from the wheel link and on the carrier element, in particular is held by means of the eccentric screw, is the integral component to the mounting part, which can be replaced in a particularly simple manner, for example, after an accident. In addition, no additional welding operations are needed to secure the mounting member to the support member. Further, it is conceivable to install the mounting part both on a left and on a right side of the motor vehicle, since the mounting part is formed for example as a mirror part. In addition, the configuration of the integral component as a mounting part enables a simple and cost-effective variant formation of the integral component.

The invention, in particular the integral component, can be used to adjust kinematics points, which are also referred to as P-points, especially on axle carriers of a motor vehicle. Furthermore, the integral component with its geometry, in particular by material accumulation, reinforces the effect in an axle construction, so that particularly high axle loads and / or test scenarios can be met. The integral component thus serves a joint adjustment of the Radlenkers, which is for example part of a suspension. About the suspension, the wheel is movably held on an example designed as a self-supporting body structure of the motor vehicle. In addition, the integral component has a gain and NVH function. The NVH function is to be understood that a particularly advantageous noise behavior, which is also referred to as NVH behavior (NVH = noise, vibration, harshness), can be realized by means of the integral component. Particularly advantageous is the fact that the integral component is designed as a mounting component and thus can be installed according to requirements with different materials, both on a front axle and on a rear axle of a motor vehicle. In this case, the mounting part, for example, in a repair case, easily replaceable. In the case of a vehicle model change with the desire to take over component designs as a reuse part, investment costs can be reduced by using the integral component, since the integral component can be used for different vehicle models or construction variants. This is advantageous in that additional welding processes often can not be realized on different systems or only with great effort. Since the integral component according to the invention can be installed without welding process and thus can be held on the carrier element, the aforementioned problems can be avoided. The integral component is thus a mounting part, which allows extensive possibilities or freedoms locally for joining in the assembly of the axle.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

1 and 2 each show a detail of a respective schematic perspective view of a holding arrangement 10 a trained as a tie rod Radlenker example 12 on a carrier element designed, for example, as a transverse bridge 14 a trained as a passenger car motor vehicle. By means of the simply referred to as a handlebar or handlebar element Radlenkers 12 is at least or exactly one wheel of the motor vehicle to lead. The motor vehicle has, for example, a construction designed in particular as a self-supporting body, with the wheel over the wheel link 12 movably held or held on the body. At the in 1 illustrated embodiment, the wheel is over the Radlenker 12 and the carrier element 14 held on the structure, wherein the Radlenker 12 relative to the carrier element 14 and is pivotable relative to the structure. In other words, that is Radlenker 12 at the holding arrangement 10 by means of a holding device 16 pivotable on the support element 14 held, so the bicycle handlebar 12 around at least one pivot axis relative to the carrier element 14 is pivotable. In the carrier element 14 it is for example an axle carrier.

To the Radlenker 12 in a particularly precise and simple manner relative to the carrier element 14 move and thereby align or position, has the holding device 16 - how very good in conjunction with 3 recognizable - separately from the Radlenker 12 and separately from the carrier element 14 trained and on the support element 14 held integral components 18 and 20 on, which in the present case separately formed and on respective, along the pivot axis away from each other sides 22 and 24 the carrier element 14 are arranged. Furthermore, the holding device comprises 16 a trained as an eccentric screw eccentric in the form of a 1 and 3 recognizable eccentric screw 26 , In addition, the holding device comprises 16 one out 2 and 3 recognizable eccentric nut 28 and an eccentric element in the form of an eccentric disc 23 , where the eccentric screw 26 the bicycle handlebar 12 penetrates and on the side 24 on which the eccentric nut 28 and the eccentric disc 23 are arranged with the eccentric nut 28 screwed, especially in the eccentric nut 28 screwed in, is. On the website 22 is the eccentric screw 26 over her on the side 22 arranged and trained as an eccentric head screw head 30 , in particular along the pivot axis, at least indirectly, in particular directly, on the side 22 arranged integral component 18 supported. On the website 24 are the eccentric mother 28 and the eccentric disc 23 at least indirectly, in particular directly, along the pivot axis or in the axial direction of the eccentric screw 26 on the side 24 arranged integral component 20 supported, wherein the eccentric disc 23 along the pivot axis directly on the integral component 20 and the eccentric mother 28 along the pivot axis via the eccentric disc 23 on the integral component 20 is supported. Here is the eccentric disc 23 along the pivot axis by means of the eccentric nut 28 against the integral component 20 curious; excited.

Out 3 is particularly well recognizable that the Radlenker 12 , in particular pivotable, on the eccentric screw 26 is stored. Here is the Radlenker 12 for example, a rubber mount 32 , in particular pivotable, on the eccentric screw 26 stored. The aforementioned pivot axis about which the Radlenker 12 relative to the carrier element 14 and preferably also relative to the eccentric screw 26 is pivotable, is in 3 recognizable and there with 34 designated. Out 1 and 3 is particularly well recognizable by the screw head 30 A bunch 36 the eccentric screw 26 is formed. In addition, the eccentric nut points 28 a covenant 38 on.

The eccentric screw 26 as well as, for example, the eccentric disc 23 are relative to the carrier element 14 and relative to the respective integral component 18 respectively 20 and preferably also relative to the Radlenker 12 around a rotation axis 40 rotatable, which in this case with the pivot axis 34 coincides. In addition, the eccentric screw 26 along a plane perpendicular to the axis of rotation 40 running first direction over the Bund 36 on the integral component 20 supported, wherein the first direction with the radial direction of the eccentric screw 26 coincides.

Accordingly, the eccentric disc 23 along the first direction and thus in the radial direction of the eccentric screw 26 or in the radial direction of the eccentric disc 23 on the integral component 20 supported. The eccentric screw 26 and the eccentric disc 23 are thereby along the first direction so on the integral components 18 and 20 supported that the eccentric screw 26 and the eccentric disc 23 and with these the Radlenker 12 by relative to the integral components 18 and 20 successively turning the eccentric screw 26 and the eccentric disc 23 relative to the integral components 18 and 20 and relative to the support member 14 are displaceable.

Out 1 and 2 it can be seen that the respective integral component 18 respectively 20 two stops spaced apart along the first direction 42 and 44 having. Here is the federal government 36 along the first direction directly to the attacks 42 and 44 of the integral component 18 supported, whereby the federation 36 along the first direction between the stops 42 and 44 of the integral component 18 is supported. The eccentric disc 23 is along the first direction between the stops 42 and 44 of the integral component 20 arranged and along the first direction directly to the attacks 42 and 44 of the integral component 20 supported. The Bund 36 or the eccentric disc 23 does not run concentric with the axis of rotation 40 but the federal government 36 or the eccentric disc 23 is eccentric to the axis of rotation 40 arranged, whereby the federation 36 or the eccentric disc 23 outside circumference is circular. Through this eccentric arrangement of the collar 36 or the eccentric disc 23 with respect to the axis of rotation 40 will be the eccentric screw 26 or the eccentric disc 23 for example, when the respective eccentric element about the axis of rotation 40 is rotated in a first direction of rotation, in one with the first direction coincident second direction relative to the carrier element 14 postponed. If the respective eccentric element is rotated, for example, in a second direction of rotation opposite to the first direction of rotation, then the respective eccentric element becomes in a third direction coinciding with the first direction and opposite to the second direction relative to the carrier element 14 postponed. Because the Radlenker 12 on the eccentric screw 26 is stored, the Radlenker 12 then, if the eccentric screw 26 in the second direction or in the third direction relative to the carrier element 14 is moved, with the eccentric screw 26 in the second direction or in the third direction relative to the carrier element 14 moved along. Thus, the Radlenker 12 by relative to the carrier element 14 and relative to the integral components 18 and 20 successively turning the eccentric screw 26 relative to the carrier element 14 can be precisely and easily moved, which, for example, the track of the motor vehicle can be adjusted as needed. Overall, it can be seen that the eccentric screw 26 an eccentric adjusting screw is, by means of which the Radlenker 12 in a particularly simple manner relative to the carrier element 14 moved and thus aligned or can be positioned.

The respective integral component 18 respectively 20 has a spreader rivet 46 on. The expanding rivet 46 is an assembly aid, by means of which, for example, the respective integral component 18 respectively 20 initially without the eccentric screw on the support element 14 can be pre-assembled and thus kept in position. After this pre-assembly, for example, the eccentric screw 26 through the carrier element 14 and by the integral components 18 and 20 put through and with the eccentric nut 28 bolted, reducing the integral components 18 and 20 , in particular along the axis of rotation 40 , against the carrier element 14 stretched and thereby on the support element 14 be attached. Because the integral components 18 and 20 separately from the carrier element 14 are formed, are the integral components 18 and 20 Mounting parts, which are particularly easy to assemble and disassemble and thus very easy to replace.

It is conceivable that the eccentric elements together or simultaneously relative to the integral components 18 and 20 and relative to the support member 14 as well as relative to the Radlenker 12 be rotated, thereby for example the Radlenker 12 on the pages 22 and 24 evenly relative to the carrier element 14 to move. Furthermore, it is conceivable that the eccentric elements are rotated relative to each other, so that, for example, the eccentric screw 26 relative to the carrier element 14 is rotated while a relative to the support element 14 Successful rotation of the eccentric disc 23 omitted. Furthermore, it is conceivable that the eccentric disc 23 relative to the carrier element 14 is rotated while a relative to the support element 14 successively turning the eccentric screw 26 omitted. As a result, for example, the Radlenker 12 be precisely aligned. In the present case, it is provided that the eccentric 23 and the eccentric screw 26 form an adjustment, which relative to the support element 14 is rotatable or rotated. Thus, for example, the eccentric 23 and the eccentric screw 26 simultaneously relative to the carrier element 14 turned. To this end, for example, the eccentric screw 26 , In particular the shaft, a longitudinal groove, in which the eccentric disc 23 positively engages. This will cause the eccentric disc 23 with the eccentric screw 26 simultaneously relative to the carrier element 14 rotated, if the eccentric screw 26 relative to the carrier element 14 is turned. The previous and following remarks on the eccentric nut 28 are easily on the eccentric disc 23 transferable and vice versa.

4 shows the respective integral component 18 respectively 20 according to a first embodiment. In the first embodiment, the integral component is 18 respectively 20 , in particular exclusively, of a metallic material, in particular of a steel. For example, the integral component 18 respectively 20 formed in the first embodiment as a stamped and bent part. The integral component 18 respectively 20 , in particular the stamped and bent part, may have a wall thickness which is, for example, in a range of from 2.25 mm to 4 mm inclusive. In particular, the wall thickness may be 2.25 mm or 3 mm or 4 mm.

Besides, it is off 4 clearly recognizable that the respective integral component 18 respectively 20 a trained as a slot through hole 48 whose longitudinal direction coincides with the aforementioned first direction. This allows the eccentric screw 26 along the first direction relative to the respective integral component 18 respectively 20 and thereby relative to the carrier element 14 be moved while the eccentric screw 26 the passage opening 48 penetrates. On one of the stops 42 and 44 opposite side has the respective integral component 18 respectively 20 respective form elements, by means of which the integral component 18 respectively 20 relative to the carrier element 14 , in particular form-fitting, positionable or positioned. In the present case, the shaped elements bulges or elevations, which are of a main body of the integral component 18 respectively 20 protrude. By means of the form elements, the respective integral component 18 respectively 20 relative to the carrier element 14 , in particular form-fitting, are positioned. The respective form element is, for example, as an enforcement in the example designed as a stamped and bent part integral component 18 respectively 20 educated. As a result, for example, on a side facing away from the respective form element of the integral component 18 respectively 20 a recess arranged, which is arranged in coincidence or congruent with the corresponding enforcement. On the side facing away from the respective form element of the integral component 18 respectively 20 is the respective stop 42 respectively 44 arranged so that on the part of the stop 42 respectively 44 the respective indentation of the respective enforcement is arranged.

5 shows a second embodiment of the respective integral component 18 respectively 20 , In the third embodiment, the integral component is 18 respectively 20 , in particular exclusively, formed from a metallic material. In particular, the integral component 18 respectively 20 be designed as a cast component, as a forging component or as a forged part or as a cast forging.

Finally shows 6 a third embodiment of the integral component 18 respectively 20 , In the third embodiment, the integral component 18 respectively 20 a basic body 50 on, which, in particular exclusively, is formed from a plastic. The main body 50 has a first passage opening 52 on, in which an insert part 54 of the integral component 18 respectively 20 is arranged. The insert part 54 runs in the circumferential direction of the passage opening 52 completely and thus closed circumferentially, so that the insert part 54 as a closed ring or the passage opening 52 is designed as a slot. The insert part 54 in turn has a second passage opening 56 on, which, as well as the passage opening 52 is designed as a slot. The eccentric screw penetrates 26 the passage opening 56 and thus the passage opening 52 , Because the through holes 52 and 56 are formed as elongated holes, while the respective longitudinal direction extends along the first direction described above, the eccentric screw 26 along the first direction relative to the support member 14 and relative to the respective one, on the carrier element 14 fixed, in particular fixed, integral component 18 respectively 20 be moved in the manner described while the eccentric screw 26 the passageways 52 and 56 penetrates.

The main body 50 is made for example by injection molding and thus as an injection molded part. In particular, the main body 50 be formed of a fiber-reinforced plastic, in particular of a glass fiber reinforced plastic. In particular, the fiber-reinforced plastic has a long-fiber matrix, in particular a long-fiber glass-fiber matrix. The insert part 54 is a metallic socket. The metallic material may be a light metal, in particular aluminum or an aluminum alloy, or a steel or a metal or steel alloy.

The main body 50 and the insert part 54 are, for example, nested slot bushes, which an inadmissible setting behavior when tightening the eccentric screw 26 or the eccentric nut 28 prevent. These are supported against each other vertically and give off a suitable load spectrum. But the plastic matrix would yield too much.
