Description

[0001] The invention relates to an arrangement for securing a screw connection element relative to a flange component, which can be fixed to a hub component by means of at least one screw connection encompassing the screw connection element; the invention relates in particular to a screw connection element for fastening the flange component of a vehicle wheel to a hub component of a vehicle hub, wherein the flange component has a through hole for a threaded section associated with the screw connection element and a centering recess surrounding the through hole, which is arranged on the outside of the flange component facing away from the hub component and which is provided with a structure pointing towards a contact surface of the screw connection element, which has adjacent structural elevations and structural depressions in the circumferential direction of the centering recess.The invention is also directed to a screw connection element, in particular to a wheel bolt or wheel nut for fastening a vehicle wheel to a vehicle hub and / or for use in an arrangement of the type according to the invention.

[0002] Connections between flange components and rotating hub components using bolted joints can loosen unintentionally if improperly tightened, leading to dangerous situations. Such connections are very common on vehicle wheels, which are usually attached to a vehicle hub by several bolted connections evenly spaced around a mounting circle on a wheel flange. These bolted connections can consist of threaded bolts permanently mounted to the hub and corresponding wheel nuts. After the wheel is positioned on the wheel hub, these nuts are screwed onto the threaded bolts, which are then inserted through the through holes in the flange, from the outside of the flange.It is also possible that the screw connections consist of wheel bolts equipped with a screw head and threaded bores provided according to the bolt circle of the through holes on the wheel hub, into which the bolts inserted from the outside of the wheel flange through the holes are screwed.

[0003] To prevent the bolted connections used to fasten vehicle wheels from loosening spontaneously during driving due to dynamic loads, various measures are known that aim to achieve high friction between the bolted connection element, i.e., the bolt head or nut, and the flange element. This includes providing a centering countersink on the outside of the wheel flange (flange component) surrounding the respective through-hole, which interacts with a correspondingly adapted contact surface of the bolted connection element, i.e., the bolt head or nut.The centering recess can be shaped like a concave spherical cap or a cone tapering inwards towards the wheel hub, and the contact surface on the bolted connection element then projects accordingly in a convex or conical shape, engaging securely in the centering recess when tightened. This known design not only ensures a large contact area between the flange component and the bolt heads or nuts securing it to the hub component, but also centers the flange component – ​​in particular, a vehicle wheel forming or incorporating it – relative to the hub component by means of the bolted connections.

[0004] From DE 102 18 339 A1, a generic arrangement is known in which the centering recesses at the through holes for the screw bolts are provided with a structure facing a contact surface of the screw connection element, which has adjacent raised and recessed features in the circumferential direction of the centering recesses. With this known arrangement, wheel bolts or nuts, such as those used for mounting light alloy wheels, are also intended to be used in the same way for painted sheet metal disc wheels. This is made possible by the fact that the coefficient of friction at the contact surfaces between the wheel nuts / bolts and the centering recesses does not change after the wheel has been initially mounted, due to the structure provided there with raised and recessed features.A layer of lacquer initially applied to the structuring is instead removed / rubbed off the contact surfaces at the centering recess when the nuts / bolts are screwed on, so that the actual contact surfaces to the screw connection elements are uncoated and thus ensure a comparatively large coefficient of friction between the parts.

[0005] For securing wheels on commercial vehicles, wheel nuts with captive wedge-shaped locking washers have been proposed, offering a very high level of security against unintentional loosening. The wedge-shaped locking washers, used in wheel nuts such as those known as "HEICO-LOCK®", feature two relative movable clamping discs. Their facing surfaces are provided with complementary wedge-shaped tooth profiles, with the leading flanks (in the tightening direction) rising gently, while the trailing flanks are steep and approximately parallel to the axis of the screw connection. This unique, well-known design of the wedge-shaped locking washers, which, when the wheel nuts are tightened, engage firmly with the typically softer material of the wheel hub via teeth facing the wheel flange, ensures that the wheel nuts cannot loosen on their own during vehicle operation.These wheel locking nuts, known for commercial vehicles, cannot be used on passenger cars where the wheel flanges are provided with centering recesses for wheel centering.

[0006] The object of the invention is to improve an arrangement of the generic type in such a way that it achieves a self-locking screw connection that cannot loosen itself even under adverse conditions. For this purpose, the invention aims to provide a suitable screw connection element.

[0007] The object of the invention is achieved with the arrangement according to the invention in that the screw connection element is provided on its contact surface with a profile that interacts with the structuring on the centering countersink. The screw connection element according to the invention is characterized by a contact surface facing the component to be fastened, which is formed by a conical or convex centering section on a screw head or a screw nut that is provided with a profile.

[0008] Unlike the prior art arrangement, in the invention not only is the centering recess surrounding the through-hole for the threaded section provided with a special structure featuring raised and recessed features, but the screw connection element, i.e., the screw head or nut, also has a profile on its contact surface that interacts with the structure on the centering recess. This achieves an approximately positive locking effect between the contact surface of the screw connection element and the centering recess into which it engages when tightened, similar to the effect of (flat) wedge-locking washers, which, however, can only be used optionally in the case of flat contact surfaces.

[0009] In an advantageous embodiment of the invention, the contact surface consists of a conical or convex centering section integrally formed on the screw head or nut of the screw connection. The contact surface is thus adapted to the shape of the centering recess, which, in a known manner, is generally tapered inwards or shaped like a convexly drawn spherical segment. Alternatively, the contact surface could be formed as part of a separate disc element arranged on a shaft section below a screw head and having a conical or convex centering section. The annular disc element is preferably slid onto the screw shaft in a known manner during the screw manufacturing process, before the screw thread is rolled.At this point, the screw diameter is still smaller than the eventual diameter on the outside of the thread. During the rolling process for thread forming, material is displaced outwards; the larger diameter on the outside of the thread then prevents the ring from loosening from the screw shank.

[0010] The centering section, which may be arranged either directly (integrally) on the screw head or on the screw nut, or alternatively is part of a separate washer / ring below the screw head, preferably has a conical angle (cone angle) or a spherical radius (ball radius) adapted to the design and shape of the centering device.

[0011] The disc or ring element preferably has an annular wall with a triangular cross-section, a central annular opening, an outer wall, and a head wall section, wherein the outer wall of the ring element extends at an angle to the longitudinal axis of the screw and forms the centering section. In a further preferred and advantageous embodiment, the screw head can have a conical or spherically convex centering collar on its underside, and the head wall section of the ring element can extend obliquely, preferably in a straight or convex direction, to the longitudinal axis of the screw in order to form a conical or convex centering guide for engagement with the centering collar on the screw head. Alternatively, however, the head wall section and the underside of the screw head can also be flat.

[0012] In a preferred embodiment of the invention, the profiling can be designed to be complementary to the structuring formed on the centering recess, so that the individual components of the profiling on one side and the structuring on the other side can essentially interlock in a form-fitting manner.

[0013] The profiling can have a plurality of detent segments arranged adjacent to each other in the circumferential direction of the centering section, whereby these can, for example, form alternating profile depressions and profile elevations.

[0014] A design has proven particularly advantageous in which the profiling forms a wave or tooth profile, which has profile elevations with at least one wave or tooth crest each and profile depressions alternating with the profile elevations, each with at least one wave or tooth base, wherein the wave or tooth crests and bases run at least substantially radially or in the direction of the generating elements for the conical or convex shape of the centering section having the contact surface.

[0015] Advantageously, the profile elevations and / or the profile depressions each have front and rear flank sections whose slopes are symmetrical to each other.

[0016] The profile elevations and / or depressions forming the profile can have different shapes, for example, in tangential section they can be triangular, sinusoidal, trapezoidal, cycloidal, rectangular or a combination of these profile shapes.

[0017] It is particularly advantageous if the screw connection has a thread pitch that is smaller than the pitch of the profile or flank sections on the contact surface of the screw connection element. For example, if a wheel bolt connection with an M12x1.5 thread is used, the thread pitch (angle of the unfolded helix) is 2.3°. The pitch of the profile on the contact surfaces of the screw head or nut is then, according to the preferred embodiment, set such that, even taking into account possible manufacturing tolerances, it is always greater than this thread pitch. In the aforementioned embodiment, this is preferably at least 2.5° and more preferably greater than 3°. In one prototype, a pitch of over 4° proved to be particularly suitable.The inclination of the front and rear flanks of the raised / recessed sections at the centering countersink is preferably greater than the thread pitch, preferably being identical to the flank pitch of the profiling, but in selected cases it can also be chosen to be greater or lesser. It has proven advantageous if the profiling at the contact surface of the screw connection element has flank sections that rise or fall circumferentially, the angle of which corresponds to the pitch of complementary sections of the structuring at the centering countersink.

[0018] The invention enables the profiled protrusions of the profiling on the contact surface of the screw connection element to engage positively with the structural recesses of the structuring on the centering countersink during assembly. When the screw connections are tightened, the profiling on the contact surface comes into contact with the structuring on the centering countersink. Due to the wave- or tooth-like design, the tightening process is no longer uniform during the final turns. When the profiled protrusions on one side and the structural protrusions on the other meet, the resulting resistance must be overcome by increasing the torque, which causes (elastic) elongation of the screw bolt or compression of the flange component in the area of ​​the centering countersink. This becomes more difficult with increasing screw-in depth and requires an increasingly higher torque.

[0019] The invention is explained in more detail below with reference to exemplary embodiments shown in the drawing. It shows: Fig. 1A and Fig. 1B a first embodiment of an arrangement according to the invention with a wheel screw and an associated part of a wheel flange of a passenger car vehicle wheel in perspective view; Fig. 1C the wheel bolt after Fig. 1A in a side view; Fig. 2A to 2C of a second embodiment of the arrangement according to the invention in the illustrations according to Fig. 1 corresponding reproductions; Fig. 3A to 3D various profile shapes with triangular profile of the profiling provided in the screw connection element according to the invention in unfolded form; Fig. 4A to 4C various profile shapes with sinusoidal profile of the profiling in one Fig. 3 corresponding representation; Fig. 5A to 5D further profile shapes of profiling with a the Fig. 3 and Fig. 4 corresponding representation; Fig. 6A and Fig. 6B a third embodiment of a screw connection element in a view ( Fig. 6A) and in longitudinal section ( Fig. 6B); and Fig. 7A and Fig. 7B a fourth embodiment of a screw connection element in a view ( Fig. 7A) and in a longitudinal section ( Fig. 7B).

[0020] The drawing reveals in the Fig. 1B and Fig. 2B shows a section of a passenger car wheel, designated 10 in its entirety, which rests with its wheel flange 11 on a wheel hub 13 visible through a bolt hole 12. The wheel hub is provided in a known manner with a threaded hole 14 with an internal thread into which a wheel bolt, designated 15 in its entirety, can be screwed, as is known for fastening vehicle wheels. It is understood that the vehicle wheel has several identically designed bolt holes 14, for example four or five holes, evenly distributed around a bolt circle, and that a corresponding number of wheel bolts 15 are provided for fastening the wheel to the wheel hub.

[0021] The through holes 12 provided in the flange component 11, of which only one is visible in each drawing, are provided in a known manner with a centering recess 16 on the outer side 17 of the wheel flange 11 facing away from the hub component 13. Each centering recess 16 has a structure 18 formed by adjacent raised sections 20 and recessed sections 21 in the circumferential direction 19 of the centering recess 16.

[0022] The arrangement according to the invention further includes a screw connection element, which is used in the Fig. 1 and Fig. 2 embodiments shown from the wheel screw 15 ( Fig. 1A, Fig. 2A). The wheel bolt 15 has a threaded section 22, which allows it to be screwed into the corresponding threaded hole 14 on the wheel hub 13 to create the screw connection. Above the threaded section 22, the wheel bolt 15 has a centering collar 23 adapted to the shape of the centering recess 16, which forms a centering section 24 with a contact surface 25 facing the flange component. When the wheel bolt 15 is screwed into the threaded bore 14, the centering section 24 engages in the centering recess 16 on the wheel flange, with the contact surface 25 bearing against the structure 18 in the centering recess 16 when the wheel bolt 15 is fully assembled. It can be seen that the shape of the centering collar 24 is adapted to the shape of the centering recess 16. In the Fig. In the embodiment shown in 1, the centering collar 24 has a conical cross-section, whereas in the embodiment shown in Fig. The embodiment shown in 2 is essentially spherical and convex in shape. Intermediate shapes are also possible.

[0023] According to the invention, the screw connection element 15 is provided on its contact surface 25 with a profile 26 that interacts with the structure 18 on the centering recess 16 and is designed to be complementary to the structure 18 formed on the centering recess 16. Accordingly, in the exemplary embodiments, the profile 26 has a plurality of locking segments 27 arranged adjacent to one another in the circumferential direction of the centering collar 24, wherein each adjacent locking segment 27 forms alternating profile recesses 28 and profile protrusions 29. The design is preferably such that the profile 26 on the contact surface 25 of the screw connection element, in the exemplary embodiments according to Fig. 1 and Fig. 2, i.e., the wheel bolt 15, has flank sections that rise or fall in the circumferential direction, the angle of inclination of which corresponds to that of complementarily designed sections of the structuring 18 on the centering recess 16, as will be explained in more detail below. The design according to the invention enables the profile protrusions 29 of the profiling 26 formed on the contact surface 25 of the centering section 24 to engage positively in the structural recesses 21 of the structuring 18 formed on the centering recess 16 in the assembled state, and conversely, the structural protrusions 20 in the centering recess 16 to interact positively with the profile recesses 28 of the profiling on the wheel bolt 15.

[0024] The shape of the profile is shown in various embodiments in the sectional view of developments in the Fig. 3, Fig. 4 to Fig. 5 more easily recognizable.

[0025] Fig. Figure 3A showed a first possible form of profiling 26, namely a tooth profile 3A in which the profile protrusions 29 and profile depressions 28 form symmetrical teeth with front flank sections 30 and rear flank sections 31, whose slopes a and b, respectively, are equal, so that the front and rear flank sections form the legs of an isosceles triangle. In this embodiment, the tooth length or tooth base X1 is greater than or equal to the height h of the teeth. A modification of the profile shape is shown on the right side of the development according to Figure 3. Fig. Figure 3A shows the profile teeth arranged at a distance X2 from each other, which corresponds to twice the tooth length X1.

[0026] A second form of profiling with tooth profile 3B shows the Fig. 3B. Here, the front flank sections 30 are inclined at a shallow angle, while the rear flank sections 31 are arranged at a right angle to the tooth root or base. The complementary structuring 18 in the centering recess 17 is shown in the right half of the drawing. Together, these elements create a locking mechanism which, due to the shallow inclination of the front flank sections, can be overcome by applying a suitable torque with appropriate (elastic) stretching / compression of the interacting parts. However, this locking mechanism is practically impossible to release, as the rear flank sections, which are then perpendicular to the direction of rotation, create a positive locking action that can hardly be overcome by applying torque alone. The profiling according to Fig. 3B is therefore reserved for special applications where disassembly of the assembled arrangement is not intended.

[0027] Fig. 3C shows a contrast Fig. 3B is a simplified form of the profile, in which the slope a of the rear flank sections 31 is significantly steeper, namely about twice as large, as the slope b of the front flank sections 30. Nevertheless, it is still possible to loosen the connection by applying a high loosening torque, e.g. with a wrench equipped with a long lever, with this toothing 3C. Fig. Finally, 3D shows a modification of the profiling according to Fig. 3C, in which the tooth crowns 33 and the tooth roots 34 are rounded with radii Rx and Ry respectively, thus reducing the surface pressures when tightening and loosening the screw connections, making the assembly and disassembly of the arrangement with this toothing 3D easier.

[0028] The Fig. Figures 4A to 4C show profiles with wave profiles. This is in Fig. The wave profile 4A shown in section as a developed section is uniformly sinusoidal. The torque required for tightening and loosening the arrangement is essentially the same as for the tooth profile 3A. The same applies to the one shown in Fig. 4B shown wave profile 4B, whose cross-section is based on a shortened cycloid, in which the radius Rz or Ry formed at the wave base is smaller than the curvature Rx defining the wave crests. Fig. Figure 4C shows a waveform 4C with non-uniform shape of the individual waves over the wavelength X1.

[0029] In the Fig. Sections 5A to 5D show alternative profile designs that can be used depending on the application. This is particularly relevant for profiling according to... Fig. The 5B structuring element, acting in conjunction with the centering recess 16, does not employ a strictly complementary design, but rather preferably a structuring element in which the structural recesses and protrusions form obliquely inclined, curved, or rounded flank surfaces that allow the vertical flank surfaces of the profiling element 5B to be overcome. For use in arrangements for fastening a vehicle wheel to a wheel hub, the pitches of the tooth flanks, at least on the respective rear flank sections 31 that are effective in the loosening direction of the screw connection element 15, are preferably larger than the pitch of the screw thread of the threaded section 22 and the threaded bore 14 interacting with it. A common screw size for a wheel screw, for example, has a pitch of 1.5 mm (M12x1.5) with a thread diameter of M12, which corresponds to a pitch angle of 2.3°.The slope of the tooth flank sections 31, especially the rear ones, is in profiles with straight-line shapes (. Fig. 3, Fig. 5A) then larger and can, for example, be more than 2.5°, preferably more than 3°. This dimension ensures that the bolted connection cannot loosen spontaneously even under unfavorable conditions, because overcoming the positive locking between the structure in the centering recess on the wheel flange and the profile from the centering section of the wheel bolt (or wheel nut) requires moving the detent segments of the profile over the structural protrusions i of the centering recess while stretching the bolted connection.

[0030] Fig. Figure 6 shows a third embodiment of a screw connection element for an arrangement according to the invention, which here is designed as a wheel nut 35. This embodiment differs from the one in Figure 6. Fig. The version shown in Figure 2 differs in that the connecting element has a threaded bore 36 instead of a threaded bolt, while in this case the wheel hub is provided with studs (not shown) at the appropriate location, onto which the vehicle wheel with the wheel flange is pushed before the wheel nuts are screwed onto the studs. The wheel nut 35 is also provided with a centering element, here in the form of a spherical seat 37, on which the profile 26 is formed according to the invention as described above.

[0031] In Fig. Figure 7 shows a further embodiment in which the centering section 124 is located on an additional component, namely a disc- or ring-shaped element 138, which is preferably, as shown, captive mounted on the wheel bolt 115 below its screw head 115a. To achieve this, the ring element 138 can be slid onto the screw shank 160 in a manner known per se during the manufacture of the screw 115, before the thread is rolled on the threaded section 122 of the screw 115, since at this point the screw diameter is still smaller than the later diameter on the outside of the threaded section 122. During the rolling process to form the thread, material is displaced outwards, and the resulting larger diameter on the outside of the thread prevents the ring element 138 from detaching from the screw shank 160.The ring element 138 shown has an annular wall 165 with a triangular cross-section, a central annular opening 166, an outer wall 167, and a head wall section 168, which together form or define the triangular cross-section. In the embodiment shown, the outer wall 167 of the ring element 138 extends at an angle to the longitudinal axis of the screw and forms a conical contact surface 125 that tapers conically towards the side of the wheel flange, the contact surface 125 being adapted to the shape of the centering recess, and the profile 126 being formed on the contact surface as described above in conjunction with the other exemplary embodiments. At the rear, i.e.,Towards the screw head side 115a, the washer or ring element 138 is provided with the head wall section 168, which, in the illustrated embodiment, runs obliquely to the longitudinal axis of the screw and forms a conical centering guide 139 into which the screw head, with a correspondingly adapted centering collar 140, fits and engages. This design ensures not only the desired centering between the respective through-hole on the wheel flange and the respective screw, but also a sufficiently high transmissible torque between the screw head 115a and the ring element 138. The underside of the screw head and the head wall of the ring element could, however, also be flat.

[0032] Instead of a precisely conical shape that runs at an angle to the wheel axis, as in Fig. 7A and Fig. As shown in Figure 7B, the centering collar or centering rim and the outer wall could also be spherically convex.

[0033] It is possible to provide additional teeth or another type of positive locking between the screw head 115a and the ring element 138. QUOTES INCLUDED IN THE DESCRIPTION
