[0002] Wheel hub, brake disc and wheel hub system

[0003] The invention relates to a wheel hub, a brake disc and a wheel hub system, in particular each for a commercial vehicle.

[0004] Wheel hubs, brake discs, and their mounting to one another are known from the prior art. In particular, brake discs are generally connected to the wheel hub in a rotationally fixed manner, for example, by bolting the wheel hub to the brake disc. During operation, the wheel hub and brake disc typically rotate around a wheel axle, and in a braking situation, the brake disc, for example, in conjunction with brake pads, serves to slow down or stop this rotation. The mounting of the brake disc to the wheel hub can be problematic. For example, there is a potential risk of confusion with the brake disc during installation, or an alternative brake disc might be selected, for example, for price or logistical reasons, which is actually less suitable or not suitable at all for the respective wheel hub than the originally intended brake disc.

[0005] It is therefore the object of the present invention to provide a wheel hub or a brake disc which can reduce errors or unfavorable decisions made by the assembler during assembly, thereby increasing safety in particular. 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 15. Further features, advantages, and embodiments will become apparent from the dependent claims, the description, and the figures.

[0006] According to the invention, a wheel hub, particularly for a commercial vehicle, comprises mounting structures for a brake disc. The mounting structures are designed differently from one another, and the wheel hub is designed to rotate about an axis of rotation. The wheel hub can be formed in one piece, particularly as a single unit together with its mounting structures. A commercial vehicle within the meaning of the invention is, in particular, a vehicle with a permissible gross vehicle weight of more than 3.5 t, preferably more than 7.5 t, and most preferably more than 15 t. The commercial vehicle can additionally or alternatively be, in particular, a road-legal and / or road-bound vehicle. The mounting structures are designed, in particular, to enable the brake disc to be attached to the wheel hub. The mounting structures can preferably be designed to fix the brake disc to the wheel hub in a rotationally fixed manner.The mounting structures can, for example, be or include holes, in particular screw holes. The holes can be through holes and / or blind holes. For example, at least one hole can be a through hole and / or at least one other hole can be a blind hole. The mounting structures, in particular the holes, can include or have an internal thread. The mounting structures can be spaced apart from one another. The mounting structures can preferably be fixed in their respective positions on the wheel hub. The mounting structures are not uniform in design. "Not uniform" within the meaning of the invention can, in particular, mean that at least one of the mounting structures is not uniform in design with respect to at least one other mounting structure.For example, several initial assembly structures may be uniform with respect to each other, while at least one further assembly structure may be designed differently from these initial assembly structures. In other words, for the purposes of the invention, the presence of one assembly structure that is not uniform with respect to every further assembly structure may suffice to define the entirety of the assembly structures as non-uniform with respect to each other. "Non-uniform" may, for example, mean that the shape or form of one assembly structure differs from the shape or form of another assembly structure. For example, the shape and / or area of ​​a cross-section, e.g., the opening cross-section of a hole, may differ between at least two assembly structures. Alternatively or additionally, "non-uniform" may be defined by the positioning of the assembly structures.At least two mounting structures can differ, for example, with respect to their axial position, their radial position, and / or their circumferential position. Within the scope 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 can also be referred to as the 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 axis of rotation and the axial direction can be the same. The radial direction is, in particular, the direction that extends radially outward from a central axis of the wheel hub, especially from the axis of rotation. The radial direction is therefore not limited to a single direction but describes a set of directions that fulfill this requirement.Accordingly, the radial position can correspond to the radial distance from the central axis or axis of rotation. In this sense, for example, two mounting structures arranged on opposite sides of the axis of rotation and at the same distance from the axis of rotation can be described as mounting structures with the same radial position. The circumferential direction can be defined by the path of a circle whose center is the central axis or axis of rotation and which encloses a surface whose normal runs parallel to the axial direction. The circumferential direction can correspond to the direction of a tangent to such a circle at any given location. The circumferential position can thus be determined as an angular position, in particular independently of the radial or axial position. If there are several orIf all mounting structures lie on a common circumcircle, their circumferential position can be determined additionally or alternatively by their position on this circumcircle. A distance in the circumferential direction can be determined as an angular distance. If two points or two mounting structures lie on a common circumcircle, the distance in the circumferential direction can be determined additionally or alternatively by the length of the circumcircle segment between these two points or mounting structures. The position of a mounting structure can be defined by its geometric center and / or centroid, or correspond to its geometric center and / or centroid. Thus, for each location, a circumferential direction and a radial direction perpendicular to it are defined. The circumferential direction and the radial direction are each perpendicular to the axial direction.Advantageously, the non-uniform design of the mounting structures can prevent the installation of an incorrect and / or unsuitable or incompatible brake disc. Furthermore, the non-uniform design can prevent incorrect installation of a correct brake disc, e.g., incorrectly oriented. For example, the mounting structures can be arranged in such a non-uniform way that a corresponding brake disc can only be mounted to the wheel hub in one specific manner. The wheel hub can preferably comprise 2 to 50, more preferably 3 to 20, and particularly preferably 8 to 12 mounting structures. For example, the wheel hub can comprise 8, 10, or 12 mounting structures. 2 to 50 mounting structures can ensure secure attachment of the brake disc to the wheel hub. 3 to 20 mounting structures can ensure particularly secure attachment while simultaneously keeping the installation effort relatively low.Eight to twelve mounting structures can additionally enable a non-uniform arrangement in a particularly practical or simple way.

[0007] Another aspect of the invention relates to a brake disc, particularly for a commercial vehicle, comprising mounting structures for connection to a wheel hub, in particular a wheel hub as described herein (before and / or following), wherein the mounting structures are designed differently from one another, and wherein the brake disc is designed 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 disc is designed to rotate about the same axis of rotation as the wheel hub when mounted.The mounting structures of the brake disc can be designed to complement the mounting structures of the wheel hub, in particular such that the brake disc is mounted to the wheel hub using both the mounting structures of the wheel hub and the mounting structures of the brake disc, and / or by a combination of the mounting structures of the brake disc and the mounting structures of the wheel hub. The mounting structures of the brake disc can be arranged such that, in one mounting position, the mounting structures of the brake disc are arranged in a mirror-symmetrical manner relative to the mounting structures of the wheel hub, the mirroring occurring in particular across a mirror plane arranged between the brake disc and the wheel hub, the normal of which runs in the axial direction. Alternatively, or additionally preferably, the mounting structures of the brake disc can also be arranged in a mirror-symmetrical manner relative to each other.The mirror plane of this symmetry can be configured such that it contains the axial direction. In other words, the mirror plane can therefore be spanned by both the axial and radial directions. Furthermore, alternatively or additionally, the mounting structures of the wheel hub can also be arranged in a mirror-symmetrical manner relative to each other. The mirror plane of this symmetry can be configured such that it contains the axial direction. In other words, the mirror plane can therefore be spanned by both the axial and radial directions.

[0008] Advantageously, the mounting structures of the wheel hub and / or the brake disc are arranged essentially on a common circumference, wherein the circumference is particularly essentially coaxial with the wheel hub and / or the brake disc. An arrangement on a common circumference can enable a particularly reliable and / or uniform fastening of the brake disc to the wheel hub. "Essentially" in this context can mean that the mounting structures differ from one another with respect to their radial position and / or their radial distance from the center of gravity of the wheel hub or brake disc by no more than 21%, preferably no more than 12%, and particularly preferably no more than 7%. Alternatively or additionally, "essentially" can mean that the mounting structures are arranged on a circumference within the limits of design accuracy.

[0009] According to one embodiment, the mounting structures of the wheel hub and / or the brake disc are arranged differently relative to each other in a circumferential direction. In other words, the angular distances between the mounting structures, particularly those closest to each other in the positive and / or negative angular or circumferential direction, can be non-uniform or unequal. In other words, at least one mounting structure of the wheel hub and / or the brake disc can have a greater distance to the nearest mounting structure of the wheel hub and / or the brake disc in the positive angular or circumferential direction than in the negative angular or circumferential direction.This principle offers the advantage of preventing the installation of an unintended brake disc and, at the same time, preventing or at least hindering the incorrect installation of an intended brake disc. Advantageously, the angular distance around the axis of rotation between a first pair of circumferentially adjacent mounting structures can differ from the angular distance between a second pair of circumferentially adjacent mounting structures. Optionally, one of the mounting structures of the first pair can also be part of the second pair. The angular distance of the first pair to the angular distance of the second pair can preferably be in a ratio of 0.016 to 0.95, more preferably 0.09 to 0.93, and particularly preferably 0.25 to 0.92. More than two pairs can also be provided, each differing in its angular distance.For example, some pairs may have an angular spacing that corresponds to the mean angular spacing of the mounting structures, and some pairs may have an angular spacing that differs from the mean angular spacing. In particular, at least one first pair may have an angular spacing that is greater than the mean angular spacing, and at least one second pair may have an angular spacing that is less than the mean angular spacing. Optionally, each pair may have an angular spacing that differs from a mean angular spacing. A mean angular spacing may, in particular, be the quotient of a full circumference (360°) and the number of mounting structures. According to one embodiment, 10 mounting structures may be provided, with a mean angular spacing of 36°.For example, 7 to 100 percent, preferably 13 to 87 percent, of the pairs can have an angular spacing that deviates from the mean angular spacing, with the remaining pairs having an angular spacing corresponding to the mean angular spacing. According to an embodiment with 10 mounting structures, six pairs can have a spacing corresponding to the mean angular spacing, with four pairs having an angular spacing that deviates from the mean angular spacing, in particular such that two pairs have a larger and two pairs a smaller angular spacing. Preferably, the pairs that deviate from the mean angular spacing can be in a ratio of 0.03 to 0.98, more preferably 0.04 to 0.96, more preferably 0.06 to 0.94, and / or in a ratio of 1.03 to 40, more preferably 1.04 to 24, more preferably 1.06 to 17.14.Pairs deviating from a mean angular spacing can be arranged next to each other in the circumferential direction. Alternatively, pairs deviating from a mean angular spacing can not be arranged next to each other in the circumferential direction, in particular such that at least one pair with the mean angular spacing is arranged between two pairs with a spacing that deviates from the mean angular spacing. In a specific embodiment, the angular spacings of ten mounting structures can be 33°–39°. o -36 o -36 o -38 o -34°- 36 o -36°-36 o -36°. In other words, the differing pairs can be arranged, for example, at positions 1, 2, 5, and 6 in the circumferential direction. In an alternative embodiment, the angular distances for ten mounting structures can be 36°. o -39 o -36 o -36 o -36 o -36 o -33 o -36 o-36 o -36°. In other words, the differing pairs can, for example, be arranged at positions 2 and 7 in the circumferential direction. In an alternative embodiment, the angular distances for ten mounting structures can be 36°. o -39°-39 o -39°- 39°-33 o -33 o -33 o -33 o -36°. In an alternative embodiment, the angular spacing for ten mounting structures can be 30°-30°. o -40 o -40 o -40 o -40 oThe angular spacing is -40°- 40°-30°-30°. In this embodiment, none of the angular spacings has the mean angular spacing of 36°. It is possible for the mounting structures to be additionally designed differently from each other in the radial direction, so that, in particular, the mounting structures are spaced at different distances from the center of the wheel hub or brake disc in the radial direction. For example, at least one mounting structure can be offset radially outwards. Alternatively, preferably, the mounting structures have the same distance from the axis of rotation in the radial direction to simplify the manufacturing of the wheel hub or brake disc.

[0010] Preferably, the mounting structures of the wheel hub and / or 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 designed so that corresponding sections of the other wheel hub or brake disc bear against them in the assembled state. The contact sections can be designed to stabilize the position of the brake disc relative to the wheel hub in the assembled state. Fastening structures can be, for example, bores, optionally threaded bores, designed for inserting or passing through fastening elements, in particular screws or bolts. The contact sections can include contact surfaces, or at least one contact surface each for the wheel hub and / or for the brake disc, and / or the fastening structures can, in particular, each include at least one hole, especially with an internal thread.At least one mounting structure, preferably each mounting structure, can simultaneously comprise a mounting section and a fastening structure. Advantageously, the mounting sections of one or more, and 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 integrated into the mounting section of the mounting structure. This allows for particularly good and homogeneous surface pressure during the mounting or fixing of the brake disc to the wheel hub.

[0011] Advantageously, the mounting sections have a non-uniform extent parallel to the direction of rotation or in the axial direction. The mounting sections can project or protrude to different degrees in the axial direction, particularly with respect to a contact surface of the mounting sections and / or with respect to the side of the mounting sections that is intended to contact the respective other wheel hub or brake disc. Advantageously, it can be provided that the mounting sections of the wheel hub and the mounting sections of the brake disc are complementary to each other and offset in opposite directions in the axial direction. A non-uniform extent can advantageously prevent mismatched wheel hubs and brake discs from being joined together and / or prevent matching wheel hubs and brake discs from being joined incorrectly rotated.

[0012] Preferably, the mounting structures of the brake disc and / or the wheel hub are arranged differently relative to each other with respect to their radial position, in particular such that the radial distance of the mounting structures from the axis of rotation of the wheel hub and / or the brake disc is not uniform. In other words, the mounting structures can be arranged differently relative to each other with respect to their radial position. Advantageously, at least two mounting structures can have different radial distances from an axis of rotation of the wheel hub and / or the brake disc and / or different radial positions.The radial distance from the axis of rotation of the wheel hub and / or the brake disc of at least one first mounting structure can be in 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 disc of at least one second mounting structure.

[0013] Advantageously, the mounting structures of the wheel hub and / or the brake disc are arranged differently with respect to their axial position, in particular such that at least two mounting structures are arranged offset from each other parallel to the direction of rotation or parallel to the axial direction. An offset of at least two mounting structures in the axial direction can correspond to a maximum axial extension of the wheel hub and / or the brake disc in a ratio of 0.17 to 0.963, preferably 0.48 to 0.94, and particularly preferably 0.75 to 0.90. Advantageously, such an embodiment allows for the efficient production of a non-uniform mounting structure.

[0014] The mounting structures of the wheel hub and / or the brake disc can project to different degrees in the axial direction. Advantageously, it can be provided that the mounting structures of the wheel hub and / or the brake disc are complementary to each other and offset in opposite directions in the axial direction with respect to an installation position of the wheel hub and brake disc. Such differing projections can advantageously prevent mismatched wheel hubs and brake discs from being assembled or aligned due to the varying axial position of the mounting structures, and / or prevent matching wheel hubs and brake discs from being assembled or aligned incorrectly.

[0015] Advantageously, the mounting structures of the wheel hub and / or the brake disc are designed such that no virtual plane exists through the center point of the wheel hub and / or the brake disc, which would create two virtual halves whose mounting structures are mirror images of each other. In particular, the virtual plane can be defined by the axial and radial directions. Advantageously, the absence of such symmetry makes it particularly easy to reliably prevent misaligned mounting, especially rotation by 180°.

[0016] Advantageously, the mounting structures of the brake disc and / or the wheel hub are designed such that a virtual plane exists through the center point of the wheel hub and / or the brake disc, creating two virtual halves whose mounting structures are mirror images of each other. This design advantageously allows for more flexible assembly and / or simpler manufacturing.

[0017] Advantageously, the extent of the mounting structures of the wheel hub and / or the brake disc in the circumferential and / or radial direction is not uniform relative to each other. For example, holes with different diameters may be provided. In particular, at least one of the mounting structures of the wheel hub and / or the brake disc may have a different extent in the circumferential and / or radial direction than at least one other mounting structure of the wheel hub and / or the brake disc.

[0018] In particular, at least one, preferably at least two, of the mounting structures of the wheel hub and / or the brake disc each comprise 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 the brake disc each comprise at least one bore, in particular a through bore. Advantageously, at least one of the bores can be non-uniform, i.e., in particular different, from at least one of the bores. A bore, in particular a through bore, can be a particularly simple way to fix the brake disc to the wheel hub. Advantageously, a non-uniform design of the bores can provide a simple way to avoid confusion of components, in particular brake discs.

[0019] Advantageously, at least one part of the mounting structures of the wheel hub and / or brake disc, in particular one of the bores, is inclined relative to the axis of rotation or the axial direction. In other words, it can be provided that at least one of the mounting structures of the wheel hub and / or brake disc, for example two to five mounting structures, is not aligned parallel to the axis of rotation or the axial direction. The inclination to the axial direction can be in the radial direction, the circumferential direction, or in a direction with components in both the radial and circumferential directions. A non-parallel inclination of the mounting structures, especially the bores, can be a particularly effective way to prevent incorrect assembly.Advantageously, the direction of extension of a portion of at least one of the mounting structures, in particular the bore, can be arranged parallel to the axis of rotation. In particular, it can be provided that at least some of the mounting structures of the wheel hub and / or the brake disc are inclined parallel to the axis of rotation or to the axial direction. This can, for example, facilitate the mounting of the brake disc on the wheel hub and / or the manufacture of the mounting structures. The inclination of the portion of the mounting structures and / or of at least one of the mounting structures to the axial direction can preferably be between 0.3° and 90°, more preferably between 1.8° and 31°, and most preferably between 3° and 17°.

[0020] Advantageously, the mounting structures of the wheel hub and / or the brake disc, in particular the bores, have different cross-sectional areas. In other words, at least one of the mounting structures of the wheel hub and / or the brake disc can have a different cross-sectional area than at least one other mounting structure of the wheel hub and / or the brake disc. The cross-sectional areas can differ, for example, in their shape and / or their area. In particular, the diameters of the cross-sectional areas of at least two mounting structures, one of the wheel hub and / or the other of the brake disc, can be different from each other. 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, and particularly preferably 0.32 to 0.68, to the diameter of at least one other cross-sectional area.With this embodiment, a particularly easy-to-produce non-uniformity can be achieved.

[0021] 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 either formed on / in a hub rib and / or are or comprise a bore, in particular a through bore. Advantageously, a design on / in a hub rib can enable particularly good integration of the mounting structures.

[0022] Advantageously, 2 to 30, preferably 3 to 20, and 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, as it combines reliable fixation with manageable assembly effort, while simultaneously allowing for reliable differentiation through non-uniformity.

[0023] Preferably, the mounting structures of the wheel hub and / or the brake disc include projecting pins or projections and / or recesses. In particular, it can be provided that one component of the wheel hub and brake disc, preferably the wheel hub, comprises pins, and the other component of the wheel hub and brake disc, preferably the brake disc, comprises complementary recesses. The pins and / or the recesses can be of different shapes. For example, the pins and / or the recesses can differ in their axial extent and / or in their diameter, particularly as measured perpendicular to the axial direction. At least one first pin can have a different diameter than at least one second pin. Additionally or alternatively, the at least one first pin can have a different axial extent than the at least one second pin.The pins can be fixed in bores, particularly those with screw threads. The pins may include notches. The notches of different pins may be of varying shapes. The recesses may have corresponding projections.

[0024] Preferably, the mounting structures of the wheel hub and / or the brake disc are arranged such that the ratio of the minimum radial distance of the mounting structures of the wheel hub or brake disc to the maximum radial distance of the mounting structures of the wheel hub or brake disc to the axis of rotation is in the range of 0.492 to 0.946, preferably in the range of 0.654 to 0.920. If the ratio is in the range of 0.492 to 0.946, this allows for particularly simple manufacturing. However, if the ratio is in the range of 0.654 to 0.920, this allows for a particularly compact connection between the brake disc and the wheel hub, thus saving valuable installation space.

[0025] Advantageously, the wheel hub has a mounting region, particularly in the form of a mounting flange. The mounting region is specifically designed as an area that defines the radial boundaries of the wheel hub. To achieve mechanical strength, the mounting flange is advantageously designed as a continuous and / or closed flange. The mounting region serves for connection to a wheel and, in particular, has mounting openings. Advantageously, these mounting openings are spaced axially from the mounting structures of the wheel hub and / or are designed as through-holes. To achieve particularly secure wheel mounting, the mounting openings of the mounting region are specifically designed to have a larger diameter than the maximum or average diameter of the mounting structures of the brake disc and / or the wheel hub.

[0026] Another 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 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 exhibit a complementary non-uniformity with respect to the design of their mounting structures.
