Description

The present invention relates to an arrangement of a wheel carrier on a steering knuckle of a commercial vehicle according to the preamble of claim 1.

Such an arrangement of a wheel carrier on a steering knuckle of a commercial vehicle is for example from the DE 10 2004 035 535 A1 known. The wheel carriers of commercial vehicles are usually exposed to high loads. In the arrangement known from the above-mentioned document, the steering knuckle is provided with a hub-like receptacle in which a rolling bearing also referred to as a compact bearing is received, wherein a bearing outer ring rests against an inner surface of the receptacle of the steering knuckle and a bearing inner ring frictionally rests on the shaft journal, the rotatably connected to the wheel carrier is connected.

The bearing inner ring is pressed, due to the rotating during driving shaft journals in the shaft journal. For axial securing of the bearing outer ring a stop is required due to assembly.

The problem is that due to high axial forces occurring at the bearing outer ring, i. in the direction of the axis of rotation of the shaft journal, a snap ring which would be inserted into a groove of the receptacle, not suitable for axial securing, since an axial clearance of the bearing outer ring is not permitted here. Even with a plurality of screws screwed axially against the receptacle ring is not suitable here due to the axial load acting on the screws and also takes up too much space.

In addition, the axial accessibility to such a stop due to the space requirement of the journal only very limited available.

The object of the present invention is to provide an arrangement of a wheel carrier on a stub axle with improved axial securing of the bearing outer ring.

This object is achieved by an arrangement of a wheel carrier on a steering knuckle with the features of claim 1.

In the arrangement according to the invention, the wheel carrier is rotatable about a rolling axis relative to the steering knuckle about a wheel rotation axis. The steering knuckle in this case has a cup-shaped receptacle in which the rolling bearing is received. A bearing outer ring of this bearing is applied to the inclusion of the steering knuckle. A bearing inner ring is frictionally engaged with a shaft journal which is rotatably connected to the wheel carrier. The bearing outer ring is axially secured to the recording by a stop.

This stop is formed as a bearing nut with an external toothing, wherein at least one engaging in the external toothing securing element is fixed to the receptacle to prevent rotation of the bearing nut.

With such an arrangement, the bearing nut with which the bearing outer ring is tightened, backlash on the recording against loosening ensured.

Such an arrangement also requires a very small axial and / or radial space.

The bearing nut and the fuse element are also easily accessible for assembly and disassembly of the arrangement.

In addition, both the securing element and the bearing nut are non-destructively detachable from the recording.

Another advantage is that the outer toothing of the bearing nut takes on a dual function, because the outer toothing of the bearing nut serves on the one hand the intervention of a tool when tightening the bearing nut and secondly it serves to secure the bearing nut by the securing element.

Advantageous embodiments are the subject of the dependent claims.

According to a first embodiment variant, the securing element is designed as a securing plate with at least one securing tooth, wherein the at least one securing tooth rests in the mounted state of the securing plate on a pointing in the release direction edge of the external toothing of the bearing nut.

Such a locking plate is inexpensive to produce and easy to mount on the recording.

The locking plate preferably has at least one extending in the circumferential direction of the receptacle slot in which a screw is received, with which the locking plate is clamped to the receptacle.

As a result, a stepless positionability of the locking plate is ensured relative to the outer toothing of the bearing nut.

In order to ensure good accessibility for a tool to the at least one screw, for example, a recess in a roller bearing spanning the shield part of the shaft journal can be provided.

Since the shaft journal is rotatable about its axis, only one recess is accordingly required even with several screws.

Accordingly, according to one embodiment, the receptacle has at least one axial screw hole in which the screw is received in the assembled state of the securing plate, wherein the securing plate is designed as a flat piece of sheet metal.

According to an alternative embodiment, the receptacle has at least one radial bore, in which the screw is received in the assembled state of the locking plate, wherein the locking plate has a resting on a lateral surface of the support, provided with at least one slot support surface from which the at least one Fuse tooth extends, wherein the at least one securing tooth is bent in the radially extending outer toothing of the bearing nut extending.

An advantage of this solution is that a recess in the shaft journal for the assembly is not required here, which further simplifies assembly and disassembly.

To prevent rotation of the locking plate, the locking plate is received according to a further advantageous embodiment in a recess on the lateral surface of the receptacle, wherein in the circumferential direction of the receptacle extending rear edge of the support surface rests against an end edge of the recess.

For stepless positionability and areal reception of the locking plate on the recording, the locking plate and the recess on the lateral surface of the receptacle is formed curved according to the lateral surface of the receptacle.

According to an alternative embodiment, the locking plate and the recess on the lateral surface of the receptacle is flat, which simplifies the processing of the recording.

In order to ensure a sufficient meshing of the at least one tooth of the locking plate in the toothing of the bearing nut, the at least one tooth of the locking plate is designed as Trapezzahn and the outer toothing of the bearing nut as involute. Conceivable are other suitable together acting tooth designs.

To further secure the screw in the screw hole of the recording a friction element, in particular a toothed disc is clamped according to a further embodiment between a screw head of the screw and the locking plate and / or between the locking plate and the receptacle.

Alternatively, it is also conceivable to impress on an underside of the screw head facing the locking plate and / or a top surface of the securing plate facing the screw head and / or a surface of the receptacle facing towards the securing plate and / or an underside of the securing plate facing the receptacle for increasing the friction between to engage the adjacent surfaces.

According to a further alternative embodiment, the locking plate is designed as a sheet-metal strip with tabs formed along a longitudinal edge.

Such a metal strip represents another cost-effective alternative to the locking plate.

Preferably, at least one of the tabs of the sheet metal strip is located in a limited by two of the teeth recess of the bearing nut. The locking plate is formed according to a preferred embodiment as the recording revolving sheet metal strip.

It is also conceivable to design the locking plate as a part-circular sheet metal strip.

According to a preferred embodiment of the locking plate formed as a sheet-metal strip, the pitch of the tabs is formed differently from the pitch of the toothing of the bearing nut.

This makes it possible that at least one tab is always fitted into a tooth gap between the teeth of the toothing of the bearing nut.

According to an alternative embodiment, the pitch of the tabs and the pitch of the teeth of the bearing nut is the same. In this case, the locking plate is clamped on the lateral surface of the receptacle and not screwed, as is the case with the aforementioned embodiments.

Such a frictional connection between such a metal strip and the recording allows a free positioning of the sheet metal strip and a reusability of the sheet metal strip.

According to yet another alternative embodiment, the locking plate is formed as positioned between the receptacle and the bearing nut band ring with at least one molded locking tooth and laterally extending bendable tabs, wherein the at least one securing tooth protrudes from the band ring in a tooth space of the bearing nut and at least one of the tabs abuts against a stop of the receptacle or rests in a groove of the receptacle.

According to a preferred embodiment of this band ring trained securing plate this is formed wavy curved perpendicular to a plane defined by the locking plate imaginary plane, whereby rattling noises of the inserted between the bearing nut and the receiving locking plate can be avoided.

At least one of the tabs of this band ring has a bore through which a screw can be passed, with which the band ring is clamped to the receptacle.

Alternatively, an axially extending passage or at least one axially extending tongue is formed on at least one of the tabs.

Thereby, the screw for fixing the band ring can be omitted, since the passage or the tab engages in a bore in the receptacle and thus secures the band ring in the circumferential direction.

The bearing nut is preferably designed as a drawn profile tube, which ensures a favorable production of the bearing nut.

In 1 is with the reference numeral 1 a steering knuckle of a commercial vehicle referred to, as in 2 shown a wheel carrier 2 for mounting a vehicle wheel is mountable.

The steering knuckle 1 is formed via a stub axle bearing (not shown) which is pivotally connected to a (not shown) axle carrier about a vertical axis of rotation.

The steering knuckle 1 has a hub-like receptacle on a side facing the vehicle wheel 4 on. In this hub-like picture 4 is a shaft journal 5 taken over a between the recording 4 and the shaft journal 5 arranged rolling bearings 3 relative to the steering knuckle 1 around a wheel axis D is rotatably mounted.

The shaft journal 5 has a cylindrical base body with a lateral surface 51 on and a flange 52 with threaded holes 53 , The wheel carrier 2 , which serves the attachment of a vehicle wheel, is doing with a variety of screws 12 with the flange 52 of the shaft journal 5 rotatably connected.

As in the 2 and 5 is shown, is a bearing outer ring 31 of the rolling bearing 3 at the reception 4 of the steering knuckle 1 , an inner surface 41 opposite the picture. A bearing inner ring 32 is frictionally engaged on the lateral surface 51 of the shaft journal 5 at. Between the bearing outer ring 31 and the bearing inner ring 32 are rolling elements 33 for rotary bearing of the bearing inner ring 32 to the bearing outer ring 31 arranged.

The bearing inner ring 32 is in a form-fitting manner in a correspondingly shaped lateral surface 51 of the shaft journal 5 recorded, in particular pressed.

For axial location fixation of the bearing outer ring 31 at the reception 4 this is by one as bearing nut 6 with an external toothing 61 trained stop axially secured.

The bearing nut 6 has an annular body 62 on, from the radially outward outer teeth 61 extends. In the axial direction, the bearing nut 6 an external thread 63 on, with the bearing nut 6 in a corresponding internal thread on the edge of the inner surface 41 the recording 4 can be screwed.

The external toothing 61 the bearing nut 6 serves for the first the simplified intervention of a tool for tightening the bearing nut 6 and second, it serves to secure the bearing nut 6 in the tightened mounting position, at which the bearing nut 6 the bearing outer ring 31 of the rolling bearing 3 in its functional position.

To prevent rotation of the bearing nut 6 is at least one in the external teeth 61 the bearing nut 6 engaging securing element on the receptacle 4 established.

This fuse element is in one in the 3 - 6 shown first embodiment variant as a locking plate 7 educated.

This in a detail in 6 shown locking plate 7 is as level, to the radius of curvature of the bearing nut 6 adapted body formed.

The locking plate 7 has a basic body 71 on, from the radially inwardly a plurality of securing teeth 72 extend. At least one of the safety teeth 72 lies in the assembled state of the lock plate 7 at a release direction of the bearing nut 6 pointing flank 64 the external toothing 61 the bearing nut 6 on, causing a loosening of the bearing nut 6 is prevented from its mounting position, for example, due to vibration or vibration during the driving operation of the commercial vehicle.

The circumferential width of the safety teeth 72 of the lock plate 7 are in the embodiment of the locking plate shown here 7 smaller than the tooth gaps 65 the external toothing 61 the bearing nut 6 ,

It is also conceivable, the width of the safety teeth 72 to the width of the tooth gaps 65 the bearing nut 6 adapt.

For continuous positioning of the lock plate 7 this has at least one in the circumferential direction U the recording 4 extending slot 73 on, in which a screw 10 is added, with the locking plate 7 at the reception 4 can be clamped.

The screw 10 extends here in the axial direction, ie in the direction of the wheel axis of rotation D , in a corresponding to the recording 4 trained threaded hole 43 , shown in 5 preferably in a radially outwardly extending survey 44 the lateral surface 42 the recording 4 is inserted at the front.

Instead of in the 3 . 4 and 6 shown embodiment of the locking plate 7 with several teeth 72 It is also conceivable only one such safety tooth 72 at the base body 71 of the lock plate 7 to form during the assembly of the lock plate 7 at the reception 4 according to the said edge 64 the external toothing 61 the bearing nut 6 by moving the lock plate 7 in the appropriate position is possible.

To increase the frictional force between the screw 10 and the locking plate 7 or the recording 4 is between a screw head 101 the screw 10 and the locking plate 7 and / or between the locking plate 7 and the recording 4 a friction element 11 , in particular clamped in the form of a toothed disc, such as in 4 easy to recognize.

It is also conceivable, instead of the friction element 11 For example impressions to increase the friction between adjacent surfaces of the screw head 101 , the top or bottom of the lock plate 7 or the locking plate 7 facing surface of the recording 4 involved.

Should the frictional connection fail in the event of overloading, the bearing nut should be loosened 6 nevertheless only limited possible because after overcoming the slot length the locking plate 7 against the screw shaft 102 the screw 10 pushes and thus a complete release of the bearing nut 6 is prevented.

For accessibility to tighten the screws 10 to ensure, as in 4 shown in the flange 52 of the shaft journal 5 assembly recesses 54 provided, through which a tool can be passed, with which the screws 10 can be attracted or solved.

In principle, only one such mounting recess is provided 54 required because the shaft journal 5 relative to the recording 4 is rotatable and accordingly the mounting recess 54 for tightening the screws 10 can be turned into the appropriate position.

A the 3 - 6 Similar variant of a securing plate is in the 7 and 8th shown.

In the in the 7 and 8th shown embodiment of the locking plate 8th shows the recording 4 , as in 8th is shown, at least one radial threaded bore 45 on, in which the screw 10 in the assembled state of the lock plate 8th is included.

The locking plate 8th here has one on a lateral surface 42 the edition 4 overlying, with at least one slot 83 provided bearing surface 81 on, according to the lateral surface 42 the edition 4 is formed curved. The safety teeth 82 extend from a side edge of the support surface 81 in the radially extending outer toothing 61 the bearing nut 6 and are accordingly bent approximately at right angles.

It is also conceivable, several such Schraubbohrungen 45 on the lateral surface 42 the edition 4 to bring in the locking plate by several screws 10 and thus to ensure a higher contact pressure and greater resistance to twisting.

The circumferential width of the safety teeth 82 of the lock plate 8th are in the embodiment shown here to the width of the tooth gaps 65 the external toothing 61 the bearing nut 6 customized.

Unless the screws 10 are placed perpendicular to the surface, the radial screw holes 45 However, should not be drilled at different angles, which would make the processing more expensive, it is conceivable, several of the slots shown axially parallel to each other in the locking plate 8th cut. Through the radial recessed screws 10 is in this embodiment, a corresponding mounting recess 54 in the flange 52 of the shaft journal 5 not mandatory.

To a twisting of the locking plate in the lateral surface 51 of the shaft journal 5 To prevent, is located in the circumferential direction U the recording 4 extending rear edge of the support surface 81 on a frontal edge 47 a recess 46 in the coat 42 is introduced and on the bearing surface 81 of the lock plate 8th rests.

In the in the 9-11 shown further embodiment is the locking plate 8th' similar to the one in the 7 and 8th shown locking plate 8th formed, with the difference that the bearing surface 81 ' of the lock plate 8th' in this case just trained.

The recess is also corresponding 46 ' on the lateral surface 42 the recording 4 just trained.

This allows the recess 46 ' the recording 4 to work both from the axial and from the radial direction.

In addition, the locking plate 8th' easier to manufacture and also a parallel arrangement of screws 10 is possible here within a single slot. However, it is also conceivable here, several slots 83 ' to arrange parallel to each other.

In the 9 and 10 are two different displacement positions of the lock plate 8th' shown to illustrate the ease of displacement of the lock plate 8th' for fitting the safety teeth 82 ' of the lock plate 8th' into the gearing 61 the bearing nut 6 ,

The safety teeth 82 ' of the lock plate 8th' are like in the 9 and 10 is shown as Trapezzähne and according to the external toothing 61 the bearing nut 6 formed as involute, allowing a sufficient meshing in each position of the lock plate 8th' ensures. Conceivable are other suitable interlocking tooth designs.

In the flat design of the lock plate 8th' grab as in 10 is shown, not in every position of the lock plate 8th' several of the safety teeth 82 of the lock plate 8th at the same time in the outer toothing 61 the bearing nut 6 one, contrary to in 7 shown curved embodiment of the locking plate 8th ,

11 shows the trained for the newly formed locking plate 8th' correspondingly shaped receptacle 4 with a flat recess 46 ' coming from a survey 44 on the coat 42 the recording 4 is excluded. Also shown here are two threaded holes 45 for receiving two the locking plate 8th' fixing screws 10 ,

In the 12 and 13 is a clearly different from the previously described embodiments variant embodiment of a locking plate shown.

The locking plate 9 is here as sheet metal strip with along a longitudinal edge integrally formed securing teeth 92 educated. The locking plate 9 is in the embodiment shown here as the recording 4 revolving metal band formed.

It is also conceivable, the backup tape example as the recording 4 form only partially enclosing sheet metal strip, for example, the scope of the recording 4 only semicircular or quarter circle-shaped.

In the in the 12 and 13 illustrated embodiment are at respective ends of the body 91 designed as a sheet metal locking plate 9 tabs 93 with recesses 94 formed, which is the inclusion of a screw 10 serve through the recesses 94 passed through and tangentially through a survey 44 the recording 4 recessed threaded hole extending the locking plate 9 fix.

Along a longitudinal edge of the body 91 are a variety of safety teeth 92 educated. The safety teeth 92 are designed as laterally extending bendable tabs.

At least one of these tabs is doing after mounting the lock plate 9 at the reception 4 in one of the tooth gaps 65 the bearing nut 6 bent.

The division of external teeth 61 the bearing nut 6 is preferably different from the division of the safety teeth 92 of the lock plate 9 , so that always at least one of the umbiegbaren tabs in one of the tooth gaps 65 the external toothing 61 the bearing nut 6 can be inflected.

In the case of a recording 4 only partially enclosing locking plate 9 It is also conceivable, the screwing of the lock plate 9 neither radial nor tangential to the reception 4 but obliquely, but preferably parallel to each other to make the screwing from one direction can. These are on the lateral surface 42 the recording 4 molded corresponding ribs or domes. The axes of the parallel glands lie on a plane perpendicular to the wheel axis.

According to a further embodiment not shown here, it is also conceivable to divide the securing teeth 92 and the division of the gearing 61 the bearing nut 6 train the same and that to the recording 4 circumferential locking plate similar to a clamp on the lateral surface 42 the recording 4 to span.

To generate a corresponding biasing force for frictional connection between the recording 4 and the lock plate 9 can serve a screw and a nut, the two tabs 93 at the ends of the body 91 of the lock plate 9 attracts accordingly.

It is also conceivable beyond a screw design as tapping screw. This is one of the ends of the lock plate 9 executed accordingly. It is also conceivable here, as a safety teeth 92 serving tabs already in the production of the teeth 61 the bearing nut 6 adjust accordingly, since the frictional connection between the locking plate 9 and the recording 4 allows a free positioning. This is the locking plate 9 also reusable.

In the in the 14 and 15 shown, to the embodiment according to 12 and 13 similar variant is the locking plate as between the recording 4 and the bearing nut 6 positioned band ring with at least one molded safety tooth 92 and laterally extending bendable tabs 93 educated.

Here is the at least one safety tooth 92 from the band ring into a tooth gap 65 the bearing nut 6 like, for example, in 14 is shown. At least one of the tabs 93 is how in 14 shown at a stop 44 the recording 4 adjacent or in a (not shown) groove of the recording 4 inverted bent.

Because the locking plate 9 not between the bearing nut 6 and the recording 4 can be trapped and in principle axially displaceable between the bearing nut 6 and the recording 4 is included since the bearing nut 6 with the bearing outer ring 31 of the rolling bearing 3 must be in contact, according to a variant, the locking plate 9 perpendicular to one of the locking plate 9 spanned imaginary plane resilient, for example, formed wavy curved.

Conceivable is a continuous waveform. Also conceivable is the formation of one or more waves between which straight sections are provided.

In the in the 16-20 shown further embodiments of the locking plate 9 are the radially extending tabs themselves as a safety tooth 92 formed in corresponding tooth spaces 65 the gearing 61 the bearing nut 6 are bendable.

For fixing the trained as a band ring locking plate 9 is one of the tabs 93 . 95 with a hole 94 provided, as exemplified in 17 is shown.

In the in the 16 and 17 embodiment shown is this tab 95 not bent and thus allows an axial screw with a screw 10 and optionally the previously described friction element 11 in an axially aligned threaded hole 45 in the survey 44 the recording 4 ,

It is also conceivable, the tab 95 on the coat 42 the recording 4 bend over to the locking plate with a radial in the receptacle 4 screwed in screw 10 to fix in the circumferential direction.

Instead of fixation using such a screw 10 is also a fixation without such a screw 10 conceivable.

This is, as in the alternative embodiment in the 18 and 19 shown at the tab 95 an axially extending passage 96 formed in an axially extending bore in the survey 44 the recording 4 protrudes.

20 shows a similar embodiment, in which instead of a pull from the tab 95 tongues extending in the axial direction 97 are bent, which the elevation 44 the recording 4 encompass radially and axially and so a rotatory securing the locking plate 9 guarantee.
