Description

The invention relates to a wheel hub, a brake disc and a wheel hub system, in particular each for a commercial vehicle.Wheel hubs, brake disks and their fastening to one another are known from the prior art. In particular, brake disks are generally connected to the wheel hub in a rotationally fixed manner, for example by screwing the wheel hub to the brake disk. During operation, the wheel hub and the brake disc typically rotate about a wheel axis and, in a braking situation, the brake disc serves, for example in cooperation with brake shoes, to decelerate or stop this rotation. The mounting of the brake disk with the wheel hub can be problematic in this case. For example, it is possible for confusion of the brake disk during assembly to potentially occur or an alternative brake disk could be selected, for example for cost-effective or logistic reasons, which in fact is less well suited or fit or not at all suitable or fit for the respective wheel hub than the actually provided brake disk.Wheel hubs with mounting structures for a brake disc are known from the prior art, wherein the wheel hub is designed to rotate about an axis of rotation. Objects of this type are disclosed, for example, in the published patent applications DE 10 2017 208 288 A1, DE 10 2017 130 290 A1, DE 10 2017 116 134 A1, DE 10 2017 116 131 A1, DE 10 2017 112 275 A1, DE 10 2011 016 029 A1 or DE 10 2010 004 866 A1.It is therefore the object of the present invention to provide a wheel hub or a brake disk which can reduce errors or unfavourable decisions of the assembler during assembly, in order in particular to increase the safety.This object is achieved with a wheel hub according to claim 1, with a brake disc according to claim 2 and with a wheel hub system according to claim 10. Further features, advantages and embodiments are evident from the dependent dependent claims, the description and from the figures.According to the invention, a wheel hub, in particular for a commercial vehicle, comprising mounting structures for a brake disc is provided. The mounting structures are formed nonuniformly with respect to one another and the wheel hub is formed to rotate about an axis of rotation. The wheel hub can be formed in one piece, in particular formed as a unit together with its mounting structures in one piece. A commercial vehicle in the sense of the invention is in particular a vehicle which has a permissible total weight of more than 3.5 t, preferably more than 7.5 t, particularly preferably more than 15 t. The utility vehicle can additionally or alternatively be, in particular, a road-suitable and / or a road-bound vehicle. The mounting structures are in particular configured to enable fastening of the brake disc to the wheel hub. The mounting structures can preferably be configured to fix the brake disc to the wheel hub in a rotationally fixed manner. The mounting structures can be or comprise holes, in particular screw holes, for example. The holes may be through-holes and / or blind holes. For example, at least one hole can be a through hole and / or at least one further hole can be a blind hole. The mounting structures, in particular the holes, can comprise or have an internal thread. The mounting structures can be formed spaced apart from one another. The mounting structures can preferably be fixed at their respective position on the wheel hub. The mounting structures are formed nonuniformly with respect to one another. Nonuniform in the sense of the invention can mean in particular that at least one of the mounting structures is formed nonuniformly with respect to at least one further mounting structure. For example, a plurality of first mounting structures may be uniform to one another, wherein, however, at least one further mounting structure is formed nonuniformly with respect to these first mounting structures. In other words, in the context of the invention, the presence of a mounting structure that is not uniform to each further mounting structure may be sufficient to define the totality of the mounting structures as being non-uniform to one another. "non-uniform" may mean, for example, that the shape or shape of a mounting structure is different from the shape or shape of a further mounting structure. For example, the shape and / or area size of a cross section, e.g. of the opening cross section of a hole, of at least two mounting structures can differ. Alternatively or additionally, "non-uniform" can be defined via the positioning of the mounting structures. At least two mounting structures can differ, for example, with regard to their axial position, their radial position and / or their circumferential circular position. In the context of this invention, the axial position is the position along an axial direction, the radial position is the position along a radial direction, and the circumferential position is the position along a circumferential direction. The circumferential direction of the circle can also be referred to as angular or circumferential direction. The axial direction runs parallel to the axis of rotation or corresponds to the direction of the axis of rotation. In other words, the rotation axis and the axial direction may be the same. The radial direction is in particular the direction which extends or points away radially outwards from a central axis of the wheel hub, in particular from the rotational axis. The radial direction is thus not fixed to a single direction, but describes a set of directions which meet this prerequisite. Accordingly, the radial position can correspond to the radial distance from the center axis or axis of rotation. In this sense, for example, two mounting structures which are arranged on opposite sides of the axis of rotation and at the same distance from the axis of rotation can be referred to as mounting structures with the same radial position. The circumferential direction of the circle may be defined by the course of a circle whose center is the center axis and the rotation axis, respectively, and which includes a surface whose normal is parallel to the axial direction. The circumferential direction of the circle can correspond here for any desired location to the direction of a tangent on such a circle. The circumferential position of the circle can thus be determined as an angular position, in particular independently of the radial position or the axial position. If a plurality of or all mounting structures lie on a common circumferential circle, the circumferential position of these mounting structures can additionally or alternatively be determined via the position on this circumferential circle. A pitch in the circumferential direction may be determined as an angular pitch. If two points or two mounting structures are located on a common circumferential circle, then the distance in the circumferential direction of the circle can additionally or alternatively be determined over the length of the circumferential circle section between these two points or mounting structures. The position of a mounting structure can be defined on the basis of the geometric center point and / or the center of gravity of the mounting structure or can correspond to the geometric center point and / or the center of gravity of the mounting structure. A circumferential direction and a radial direction perpendicular thereto are thus defined for each location. The circumferential direction of the circle and the radial direction each run perpendicular to the axial direction. Advantageously, the non-uniform configuration of the mounting structures makes it possible to prevent mounting of a wrong and / or unsuitable or inappropriate brake disk. Furthermore, the non-uniform configuration may possibly prevent incorrect, for example incorrectly rotated, mounting of a correct brake disk. For example, the mounting structures can be arranged nonuniformly in such a way that an associated brake disk can be mounted on the wheel hub only in an intended manner. The wheel hub can preferably comprise 2 to 50, preferably 3 to 20, particularly preferably 8 to 12, mounting structures. For example, the wheel hub may comprise 8, 10 or 12 mounting structures. 2 to 50 mounting structures can enable a secure fastening of the brake disc to the wheel hub. 3 to 20 mounting structures can enable particularly secure fastening and at the same time keep the assembly effort relatively low. 8 to 12 mounting structures can additionally make possible a non-uniform arrangement particularly expediently or simply.A further aspect of the invention relates to a brake disc, in particular for a commercial vehicle, comprising mounting structures for a connection to a wheel hub, in particular a wheel hub as described herein (above and / or below), wherein the mounting structures are formed nonuniformly with respect to one another, wherein the brake disc is formed to rotate about an axis of rotation. All features, properties and advantages described in connection with the wheel hub can be transferred analogously to the brake disc. In particular, the brake disk is designed to rotate about the same axis of rotation as the wheel hub in the assembled state. The mounting structures of the brake disc can be designed to be complementary to the mounting structures of the wheel hub, in particular in such a way that the brake disc is mounted on the wheel hub by means of both the mounting structures of the wheel hub and the mounting structures of the brake disc and / or by interaction of the mounting structures of the brake disc and the mounting structures of the wheel hub. The mounting structures of the brake disk can be arranged in such a way that in a mounting positioning the mounting structures of the brake disk are arranged mirror-symmetrically to the mounting structures of the wheel hub, wherein the mirroring takes place in particular on a mirror plane arranged between the brake disk and the wheel hub, the normal of which plane runs in the axial direction. Alternatively or additionally preferably, the mounting structures of the brake disc can also be arranged mirror-symmetrically to one another. The mirror plane of this symmetry can be designed in such a way that this mirror plane contains the axial direction. In other words, the mirror plane can therefore be spanned by the axial direction and the radial direction. Furthermore, alternatively or additionally preferably, the mounting structures of the wheel hub can also be arranged mirror-symmetrically to one another. The mirror plane of this symmetry can be designed in such a way that this mirror plane contains the axial direction. In other words, the mirror plane can therefore be spanned by the axial direction and the radial direction.Advantageously, the mounting structures of the wheel hub and / or the brake disc are arranged substantially on a common circumference, wherein the circumference is in particular formed substantially coaxially to the wheel hub and / or to the brake disc. An arrangement on a common circumference can enable a particularly reliable and / or uniform fastening of the brake disk to the wheel hub. "Essentially" can mean in this context that the mounting structures differ from one another with respect to their radial position and / or with respect to their distance in the radial direction from the center of gravity of the wheel hub or brake disk by not more than 21%, preferably not more than 12%, particularly preferably by not more than 7%. Alternatively or additionally, "substantially" can mean that the mounting structures are arranged on a circle within the scope of a design precision.According to one embodiment, the mounting structures of the wheel hub and / or of the brake disc are arranged non-uniformly with respect to one another with respect to their position in a circumferential direction of the circle. In other words, it can be provided that the angular distances between the mounting structures, which are respectively closest to one another, in particular in the positive and / or negative angular or circumferential direction or circumferential direction, are formed nonuniformly or unequally. In other words, at least one mounting structure of the wheel hub and / or of the brake disk can have a greater distance from the next mounting structure of the wheel hub and / or of the brake disk in the positive angular or circumferential direction or circumferential direction than in the negative angular or circumferential direction or circumferential direction. This principle can have the advantage that, on the one hand, mounting of a brake disk which is not provided can be prevented and that, on the other hand, twisting attachment of a brake disk which is provided can also be prevented or at least made more difficult. Advantageously, an angular distance about the axis of rotation between a first pair of mounting structures adjacent in the circumferential direction of the circle can differ from an angular distance between a second pair of mounting structures adjacent in the circumferential direction of the circle. Optionally, one of the mounting structures of the first pair may also be part of the second pair. The angular distance of the first pair can be preferably in a ratio of 0.016 to 0.95, preferably 0.09 to 0.93, particularly preferably 0.25 to 0.92, to the angular distance of the second pair. It is also possible to provide more than two pairs which differ in each case with regard to their angular spacings. For example, some pairs may have an angular distance corresponding to an average angular distance of the mounting structures and some pairs have an angular distance deviating from the average angular distance. In particular, at least one first pair can have an angular distance which is greater than the mean angular distance, wherein at least one second pair has an angular distance which is less than the mean angular distance. Optionally, it may be provided that each pair has an angular distance that is different from a mean angular distance. An average angular distance can be, in particular, the quotient of a full circumference or 360°, and the number of mounting structures. According to an embodiment, 10 mounting structures may be provided, wherein the average angular distance is 36°. For example, 7 to 100 percent, preferably 13 to 87 percent, of the pairs can have an angular distance differing from a mean angular distance, wherein the remaining pairs have an angular distance corresponding to the mean angular distance. According to an embodiment with 10 mounting structures, six pairs can have a distance corresponding to the mean angular distance, wherein four pairs have an angular distance differing from the mean angular distance, in particular such that two pairs have a larger and two pairs have a smaller angular distance. Preferably, the pairs which deviate from the mean angular distance can be in a ratio of 0.03 to 0.98, preferably 0.04 to 0.96, particularly preferably 0.06 to 0.94, to the mean angular distance, and / or in a ratio of 1.03 to 40, preferably 1.04 to 24, particularly preferably 1.06 to 17.14. Pairs deviating from an average angular distance can be arranged next to one another in the circumferential direction of the circle. Alternatively, the pairs deviating from an average angular distance cannot be arranged next to one another in the circumferential direction, in particular in such a way that at least one pair having the average angular distance is arranged between two pairs having a distance deviating from the average angular distance. In a specific embodiment, the angular distances for ten mounting structures may be 33°-39°-36°-36°-38°-34°-36°-36°-36°-36°-36°. In other words, the deviating pairs can be arranged, for example, at positions 1, 2, 5 and 6 in the circumferential direction of the circle. In an alternative embodiment, the angular distances for ten mounting structures may be 36°-39°-36°-36°-36°-33°-33°-36°-36°-36°-36°. In other words, the deviating pairs can be arranged, for example, at positions 2 and 7 in the circumferential direction of the circle. In an alternative embodiment, the angular distances for ten mounting structures may be 36°-39°-39°-39°-33°-33°-33°-33°-33°-33°-36°. In an alternative exemplary embodiment, the angular distances for ten mounting structures may be 30°-30°-40°-40°-40°-40°-40°-40°-40°-40°-30°-30°. In this exemplary embodiment, none of the angular distances has the mean angular distance of 36°. It can be provided that the mounting structures are additionally formed nonuniformly with respect to one another in the radial direction, so that in particular the mounting structures are spaced apart from the center of the wheel hub or brake disk to different extents in the radial direction. For example, at least one mounting structure can be offset radially outwards. Alternatively preferably, however, the mounting structures have the same distance from the axis of rotation in the radial direction in order to simplify the manufacture of the wheel hub or the brake disc.Preferably, the mounting structures of the wheel hub and / or of the brake disc are at least partially contact sections and / or fastening structures. Contact sections can be sections of the wheel hub or brake disc which are designed such that corresponding sections of the other wheel hub or brake disc in the mounted state respectively contact them. The contact sections can be configured to stabilize the position of the brake disk relative to the wheel hub in the assembled state. Fastening structures can be, for example, bores, optionally threaded bores, which are designed for the insertion or passage of fastening elements, in particular screws or bolts. The contact sections can comprise contact surfaces or respectively at least one contact surface for the wheel hub and / or for the brake disc and / or the fastening structures can comprise, in particular respectively, at least one hole, in particular with an internal thread. At least one mounting structure, preferably each mounting structure, can simultaneously comprise an abutment portion and a fastening structure. Advantageously, the contact sections of the or some, in particular all, mounting structures surround the respective fastening structure of the mounting structure. In other words, the fastening structure of the mounting structure can thus be introduced into the contact section of the mounting structure. As a result, a particularly good and homogeneous surface pressure can be achieved during the mounting or fixing of the brake disc on the wheel hub.Advantageously, the contact sections have a mutually non-uniform extension parallel to the extension direction of the axis of rotation or in the axial direction. The contact sections can project or project to different extents in the axial direction, in particular with regard to a contact surface of the contact sections and / or with regard to the side of the contact sections which is provided for the contact of the respective other wheel hub or brake disc. Advantageously, it can be provided that contact sections of the wheel hub and contact sections of the brake disc are offset in the axial direction in a complementary manner opposite to one another. A non-uniform extension may advantageously allow non-matching wheel hubs and brake disks to be unavailable together and / or matching wheel hubs and brake disks to be unavailable together in a non-mistwisted manner.The mounting structures of the brake disk and / or of the wheel hub are preferably arranged non-uniformly with respect to their position in the radial direction, in particular in such a way that a radial distance of the mounting structures from the axis of rotation of the wheel hub and / or of the brake disk is non-uniformly formed for the mounting structures. In other words, the mounting structures can be arranged non-uniformly with respect to each other with respect to their radial position. Advantageously, at least two mounting structures can have a different radial distance from an axis of rotation of the wheel hub and / or of the brake disc and / or a different radial position. The radial distance from the axis of rotation of the wheel hub and / or the brake disk of at least one first mounting structure can be at a ratio of 0.62 to 0.95, preferably 0.73 to 0.93, particularly preferably 0.79 to 0.90, to the radial distance from the axis of rotation of the wheel hub and / or the brake disk of at least one second mounting structure.Advantageously, the mounting structures of the wheel hub and / or of the brake disc are arranged non-uniformly with respect to their axial position, in particular in such a way that at least two mounting structures are arranged offset with respect to one another parallel to the direction of extent of the rotational axis or parallel to the axial direction. An offset of at least two mounting structures in the axial direction can be in a ratio of 0.17 to 0.963, preferably 0.48 to 0.94, particularly preferably 0.75 to 0.90, to a maximum extent of the wheel hub and / or of the brake disc in the axial direction. Advantageously, with such an embodiment, an efficiently producible non-uniformity of the mounting structures can be made possible.The mounting structures of the wheel hub and / or of the brake disc can project or project to different extents in the axial direction. Advantageously, it can be provided that mounting structures of the wheel hub and / or of the brake disk are offset in the axial direction in a complementary manner opposite to one another with respect to an installation position of the wheel hub and brake disk. A different protrusion can advantageously make it possible that non-matching wheel hubs and brake disks cannot be joined together or cannot be brought into contact with one another on account of the varying axial position of the mounting structures and / or that matching wheel hubs and brake disks cannot be joined together or brought into contact with one another in a incorrectly rotated manner.Advantageously, the mounting structures of the wheel hub and / or the brake disc are configured such that there is no virtual plane through the center point of the wheel hub and / or the brake disc, by which two virtual halves are produced, the mounting structures of which are mirror-symmetrical to one another. In particular, the virtual plane can be spanned by the axial direction and the radial direction. Advantageously, due to the lack of such symmetry, it may be possible in a particularly reliable manner to prevent a rotated mounting, in particular rotated by 180°.Expediently, the mounting structures of the brake disc and / or of the wheel hub are designed in such a way that a virtual plane exists through the center point of the wheel hub and / or of the brake disc, by means of which two virtual halves are produced, the mounting structures of which are mirror-symmetrical to one another. Advantageously, with this configuration, more flexible assembly and / or simpler production can be made possible.Advantageously, an extension of the mounting structures of the wheel hub and / or of the brake disc in the circumferential direction of the circle and / or in the radial direction is non-uniform with respect to one another. For example, holes with a non-uniform diameter can be provided. In particular, at least one of the mounting structures of the wheel hub and / or of the brake disc can have a different extent in the circumferential direction of the circle and / or in the radial direction than at least one further of the mounting structures of the wheel hub and / or of the brake disc.In particular, at least one, preferably at least two, of the mounting structures of the wheel hub and / or of the brake disc is in each case a bore, in particular a through bore. Alternatively or additionally, at least one, preferably at least two, of the mounting structures of the wheel hub and / or of the brake disc each comprises at least one bore, in particular through bore. Advantageously, at least a first of the bores can be formed non-uniformly, i.e. in particular differently, than at least a second of the bores. A bore, in particular a through bore, can be a particularly simple possibility for fixing the brake disc on the wheel hub. Advantageously, a simple possibility to realize can be provided by a non-uniform configuration of the bores in order to avoid confusion of components, in particular brake disks.Advantageously, an extension direction of at least a part of the mounting structures of the wheel hub and / or of the brake disc, in particular of one of the bores, is inclined to the extension direction of the rotational axis or to the axial direction. In other words, it can be provided that at least one of the mounting structures of the wheel hub and / or of the brake disc, for example two to five mounting structures, is not aligned parallel to the axis of rotation or to the axial direction. The inclination to the axial direction can be provided in particular in the direction of the radial direction, in the direction of the circumferential direction or in a direction with components in the radial direction and the circumferential direction. With a non-parallel inclination of the mounting structures, in particular of the bores, incorrect mounting can be prevented particularly effectively. Advantageously, a direction of extension of a part of at least one further of the mounting structures, in particular of the bore, can be arranged parallel to the axis of rotation. In particular, it can be provided that at least some further of the mounting structures of the wheel hub and / or of the brake disc are inclined parallel to the axis of rotation or to the axial direction. For example, the mounting of the brake disk on the wheel hub and / or the production of the mounting structures can thus be facilitated. The inclination of the part of the mounting structures and / or of the at least one of the mounting structures to the axial direction can preferably be between 0.3° and 90°, preferably between 1.8° and 31°, particularly preferably between 3° and 17°.Advantageously, the mounting structures of the wheel hub and / or of the brake disc, in particular the bores, have mutually non-uniform cross-sectional areas. In other words, at least one of the mounting structures of the wheel hub and / or of the brake disc can have a different cross-sectional area than at least one further of the mounting structures of the wheel hub and / or of the brake disc. The cross-sectional areas can differ, for example, in terms of their shape and / or in terms of their area. In particular, diameters of the cross-sectional areas of at least two mounting structures, in each case of the wheel hub and / or of the brake disc, can be configured differently from one another. The diameter of at least one first cross-sectional area can be in a ratio of 0.07 to 0.93, preferably 0.26 to 0.76, particularly preferably 0.32 to 0.68, to the diameter of at least one further cross-sectional area. With this embodiment, it is possible to achieve a non-uniformity that can be produced particularly easily.Advantageously, at least one of the mounting structures is formed on / in a hub rib of the wheel hub, wherein the mounting structures are in particular each formed either on / in a hub rib and / or are or comprise a bore, in particular a through bore. Advantageously, a formation on / in a hub rib can enable particularly good integration of the mounting structures.Expediently, 2 to 30, preferably 3 to 20, particularly preferably 8 to 12, mounting structures are provided on / in the wheel hub and / or on / in the brake disc. This number can be particularly advantageous for fastening in that a reliable fixing can be combined with a manageable assembly effort and wherein at the same time a reliable distinguishability can be achieved by non-uniformity.Preferably, the mounting structures of the wheel hub and / or the brake disc are protruding pins or protrusions and / or recesses. In particular, it can be provided that one of the wheel hub and brake disc, preferably the wheel hub, comprises pins and the other of the wheel hub and brake disc, preferably the brake disc, comprises recesses complementary thereto. The pins and / or the recesses may be formed nonuniformly. For example, the pins and / or the recesses may be non-uniform with respect to their extension in the axial direction and / or with respect to their diameter, in particular dimensioned perpendicular to the axial direction. At least one first pin may have a different diameter than at least one second pin. Additionally or alternatively, the at least one first pin can have a different extension in the axial direction than the at least one second pin. The pins can be fixed, for example, in bores, in particular provided with screw threads. The pins may include notches. The indentations of different pins may be nonuniform. The recesses can have projections corresponding to the notches.The mounting structures of the wheel hub and / or of the brake disk are preferably arranged in such a way that the ratio of the minimum distance of the mounting structures of the wheel hub or of the brake disk in the radial direction to the axis of rotation to the maximum distance of the mounting structures of the wheel hub or of the brake disk in the radial direction to the axis of rotation is in a range from 0.492 to 0.946, preferably in a range from 0.654 to 0.920. If the ratio is in a range from 0.492 to 0.946, particularly simple production can be effected as a result. However, if the ratio is in a range from 0.654 to 0.920, this can achieve the result that a particularly compact connection between brake disc and wheel hub can be obtained, so that valuable installation space can be saved.Advantageously, the wheel hub has a mounting region, in particular in the form of a mounting strip. The mounting region is in particular formed as a region delimiting the wheel hub in the radial direction. In order to achieve a mechanical strength, the mounting flange is advantageously designed as a circumferential and / or closed flange. The mounting region serves for connection to a wheel and has in particular mounting openings. Advantageously, these mounting openings are spaced apart from the mounting structures of the wheel hub in the axial direction and / or are formed as through openings. In order to achieve a particularly secure fixing of a wheel, the mounting openings of the mounting region are in particular formed in such a way that they have a larger diameter than the maximum or the averaged diameter of the fastening structures of the mounting structures of the brake disc and / or of the wheel hub.A further aspect of the invention is a wheel hub system comprising a wheel hub and / or a brake disc according to one of the preceding claims. All advantages and features of the wheel hub and / or of the brake disc can be transferred analogously to the wheel hub system and vice versa. In particular, it can be provided that the wheel hub and the brake disc have a mutually complementary non-uniformity with regard to the configuration of their mounting structures.Individual ones of the features and embodiments mentioned above can be combined with one another, and the advantages assigned to the individual features also apply to a combination of these features.
