Description

Technical Field

[0001] This invention relates to a wheel bearing assembly. Background Technology

[0002] according to Figure 1 A known unit includes a wheel bearing assembly comprising a hub element 10 made of cast iron, wherein two tapered roller bearings 12 and 14 are arranged. The outer rings of the tapered roller bearings are press-fitted in. The inner rings of the tapered roller bearings are arranged on a hollow axle section (not shown). Using a drive shaft (not shown) extending inside the axle section, torque is transmitted to the hub element via a flange (not shown) of the drive shaft. A rim (not shown) and a brake disc element (not shown) are screwed (or threaded) to the hub element at a radially outer region 20. The inner diameter of the brake disc element is smaller than the outer diameter of the hub element.

[0003] Furthermore, wheel bearings are known in the front axles of trailers and trucks, where the hub and outer rim are implemented as a single unit. Here, the hub includes a flange, which is a protrusion on another generally cylindrical shell-like outer surface of the hub. The flange includes a hole through which the wheel adapter is typically attached, and the rim is screwed directly onto the flange at this hole. In the fully assembled state, the brake disc element is mounted in the inboard side environment of the wheel bearing. The inner diameter of the brake disc element is larger than the maximum outer diameter of the wheel bearing, allowing the brake disc element to be moved on the wheel bearing during disassembly. Summary of the Invention

[0004] The present invention is particularly aimed at providing a wheel bearing unit of the type described above with a long service life. This objective is achieved by a wheel bearing assembly comprising at least two rolling bearings configured to jointly participate in at least one wheel, wherein at least one of the rolling bearings includes at least one bearing ring attached to a drive shaft for transmitting propulsion, wherein at least one braking element of the wheel bearing assembly is immovable relative to the bearing ring, wherein a connecting unit of the wheel bearing assembly connects the braking element to the bearing ring, wherein by removing the connecting unit from the bearing ring, the braking element can be removed from the rolling bearing and can be positioned at any distance from the bearing ring, wherein it is not necessary to remove any of the rolling bearings, or even to remove only part of the rolling bearings.

[0005] The present invention relates to a wheel bearing assembly comprising at least two rolling bearings configured to jointly participate in at least one wheel, wherein at least one of the rolling bearings includes at least one bearing ring attached to a drive shaft for transmitting propulsion, and at least one braking element of the wheel bearing assembly is immovable relative to the bearing ring, and a connecting unit of the wheel bearing assembly connects the braking element to the bearing ring.

[0006] A method has been proposed that allows the braking element to be removed from the rolling bearing by removing the connecting element from the bearing race, and allows the braking element to be positioned at any distance from the bearing race, without needing to remove any of the rolling bearings, or even only partially remove them. This enables a long service life for the wheel bearing assembly. Specifically, it allows for the omission of rolling bearing removal during braking element replacement, as the braking element can be removed radially outside and above the rolling bearing, and the new braking element can be attached in a similar manner. This reliably prevents errors that reduce service life during rolling bearing removal and subsequent installation, and reliably prevents the entry of contaminants that reduce service life into the rolling bearing. The far-and-away largest share of such errors is caused by failures due to improper installation requirements, such as the use of unsuitable tools during attachment of the inner race of the rolling bearing via a nut, which is surprising.

[0007] The bearing ring is preferably the outer ring.

[0008] Advantageously, the braking element is configured as a brake disc element, thereby achieving particularly effective braking.

[0009] In particular, the connecting unit may include screws, wherein the braking element is screwed directly onto the bearing ring, wherein these screws may simultaneously secure the rim or, in particular, the adapter to the bearing ring.

[0010] Preferably, the drive shaft is connected to the bearing race by means of a screw screwed into a recess on the first end side of the bearing race. This saves installation space in the radial direction.

[0011] Advantageously, the distance between the braking element and the second end of the bearing ring opposite the first end is less than the distance from the first end. This allows for better utilization of installation space.

[0012] Furthermore, it is proposed that the bearing ring lacks shoulders and flanges on its radially outer side for screws to be screwed into the hub elements for attaching the drive shaft and / or the wheel bearing assembly. In this way, the bearing ring ( / the bearing ring is manufactured) is more compact in the radial direction.

[0013] Furthermore, the wheel bearing assembly includes screws and / or studs, with at least one hub element attached to the bearing ring via the screws and / or studs. This allows for a relatively low weight. Preferably, the braking element is securely screwed onto the hub element, thereby enabling easy removal.

[0014] Advantageously, the hub element is supported on the bearing ring at a radially inner side of the hub element, at a distance greater than 30% (preferably greater than 50%) of the maximum axial length of the bearing ring. This allows for particularly high rigidity.

[0015] Furthermore, it is proposed that the wheel bearing assembly includes a flange of the drive shaft, the flange being at least partially disposed in the axial direction of the wheel bearing assembly between the attachment region of the hub element and the bearing race, the hub element being attached to the bearing race via the attachment region. This allows the hub element to be removed without removing the flange of the drive shaft, which means a significant reduction in workload.

[0016] Preferably, the wheel bearing assembly includes at least one positioning unit that enables the hub element to be positioned relative to the bearing ring at a specific position in the circumferential direction with respect to the bearing ring. This allows for simple and accurate installation, wherein the individual fitting surfaces of the hub element and the bearing ring are fully abutted against each other.

[0017] Furthermore, the proposed wheel bearing assembly includes at least one screw that at least facilitates attachment of the drive shaft to the bearing race without penetrating the area of ​​the hub element. This allows the installer to identify how the hub element is positioned relative to the bearing race in the circumferential direction during attachment to the bearing race without angular rotation of the components, ensuring full-surface force transmission due to recesses on both components, and also contributing to rust prevention.

[0018] Advantageously, the wheel bearing assembly includes at least one mounting device. To achieve maximum stable connection between the hub element and the bearing ring, the at least one mounting device requires the hub element to have a specific orientation or one of a specific number of orientations relative to the bearing ring in the circumferential direction, wherein the specific number is less than six. This allows the radially outward extending embodiment of the bearing ring and the radially inward extending embodiment of the hub element to abut against each other, thereby achieving good force transmission between the hub element and the bearing ring.

[0019] In a completely uninstalled state, with neither the braking element nor the flange connected to any other component (or component), the flange of the drive shaft is preferably fully movable through the through-hole of the braking element. This allows the braking element to be removed without removing the flange of the drive shaft from the bearing race of the rolling bearing, thereby significantly reducing the workload of replacing the braking element.

[0020] Furthermore, it is proposed that the rolling bearing is a tapered roller bearing, and the tapered rollers in the two tapered roller rows have different dimensions. "Different dimensions" should be understood to specifically mean that the height and / or surface area and / or base surface of the tapered rollers are different from each other. In this way, a small extension in the radial direction of the rolling bearing can be achieved.

[0021] Preferably, the inner ring of the rolling bearing is arranged on the hollow shaft portion (or axle portion) of the wheel bearing assembly. This allows for a compact design. In particular, it allows the drive shaft to extend inside the shaft portion.

[0022] Advantageously, the wheel bearing assembly includes at least one sealing element that shields the radially spaced area between the bearing race and the brake element. This effectively prevents rusting in the assembly area between the bearing race and the wheel hub element.

[0023] Furthermore, a device, particularly for trucks, is proposed, comprising a wheel bearing assembly and a drive shaft as described above. Specifically, the wheel is part of the device.

[0024] Furthermore, a method is proposed for removing a brake element from a wheel bearing assembly, particularly the wheel bearing assembly described above, wherein the brake element and the outer ring of the wheel bearing assembly are moved relative to each other, wherein the outer ring reaches completely through the through-hole of the brake element. This results in a long service life. In particular, it prevents errors that could occur during brake element replacement, such as the need to remove and subsequently install the rolling bearing, which could adversely affect the service life of the rolling bearing in further operations.

[0025] Furthermore, a method is proposed for mounting components of a wheel bearing assembly, particularly the wheel bearing assembly described above, wherein the components are attached to a bearing ring by screws. The components are oriented with respect to the circumferential direction of the bearing ring such that the number of screws available for attaching the components to the bearing ring in this orientation is greater than the number of screws available for attaching the components to the bearing ring in other orientations relative to the bearing ring and with respect to the circumferential direction, in which the components can also be screwed onto the bearing ring. This results in a long service life. In particular, it prevents the components from being attached with a suboptimal number of screws.

[0026] The component (or constituent component) is a hub element or a braking element.

[0027] Furthermore, a kit for assembling a wheel bearing assembly, particularly the wheel bearing assembly described above, is proposed. The kit includes a hub element, a bearing ring, and a specific number of attachment elements. After assembly, all parts of the kit can be installed with the hub element oriented relative to the bearing ring in a specific manner or in a specific number of ways about the circumferential direction of the bearing ring, wherein the specific number is less than six. This allows for a long service life. In particular, the assembly's service life can be improved. Furthermore, optimal force transmission can be ensured. Attached Figure Description

[0043] Figure 2 and Figure 3 The present invention illustrates a wheel bearing assembly comprising two rolling bearings 22, 24 configured as tapered roller bearings. The two rolling bearings rotatably support a wheel rim 64 of the wheel bearing assembly relative to a shaft portion 62. In a fully mounted state, the wheel rim 64 is immovable relative to the body of a motor vehicle in which the wheel bearing assembly is part. The motor vehicle is configured as a truck. In the fully mounted state, the wheel rim is part of the wheel. The two rolling bearings have a common bearing ring 26, which is the outer ring of the two rolling bearings. A drive shaft 28 extends through the shaft portion 62 and is attached to the bearing ring 26. A braking element 30 of the wheel bearing assembly is rigidly attached to the bearing ring 26 via a connecting unit 32 of the wheel bearing assembly. The braking element 30 is configured as a brake disc element. The braking element is arranged inside the housing of the wheel bearing assembly. The connecting unit 32 includes a hub element 42, a screw 34, a flange 46 of the drive shaft, and additional screws for attaching the braking element 30 to the hub element. Screw 34 passes through flange 46 and through the opening of hub element 26 and is screwed into opening 36 of bearing ring 26. Therefore, flange 46 and hub element 42 are also attached to bearing ring 26. Opening 36 is located on end side 38 of bearing ring. The bearing ring does not allow screws to be screwed into the shoulder for attachment of drive shaft and / or hub element 42 on its radially outer side 40.

[0044] By loosening screw 34, flange 46 (including the drive shaft) and hub element 42 can be removed from bearing ring. The central through-hole 54 of brake element 30 is configured to allow bearing ring 26 to move completely through it. Therefore, after loosening screw 34 along with flange 46 and hub element 42, brake element 30 can also be completely removed and pulled out of the rolling bearing, and can be at any distance from bearing ring 26. Loosening screw 34 and removing flange 46 and hub element 42 from bearing ring removes connecting unit 32, without even partially removing the rolling bearing. In the method for removing brake element 30, the brake element is removed from bearing ring 26 as described above, reliably preventing damage to the rolling bearing and the entry of contaminants into the rolling bearing. Bearing ring 26 is attached to shaft portion 62 via rolling elements of rolling bearing 22. Inner rings 60 of rolling bearings 22, 24 are securely screwed onto the external threads of shaft portion 62 by nuts 66. To securely tighten the nut, a torque of approximately 1000 Nm to 1200 Nm is required, which is not achievable in a controlled manner in some small workshops.

[0045] The bearing ring 26 includes a region configured as a cylindrical shell on its radially outer side. The hub element is supported on the bearing ring 26 on its radially inner side 44, at a distance greater than 50% of the maximum axial length of the bearing ring 26. The surface area supporting the hub element is configured as a cylindrical shell. A slurry, typically used to prevent fretting wear and corrosion, can be applied to this surface area.

[0046] Specifically, the wheel bearing assembly can be configured to withstand a maximum load of 13 tons. The minimum inner diameter of the braking element can be, for example, 19.5 inches or 22.5 inches. The hub element is made of cast iron.

[0047] exist Figures 4 to 13 Alternative exemplary embodiments are depicted. Essentially identical components, features, and functions are generally numbered using the same reference numerals. However, to distinguish the exemplary embodiments, the letters "a", "b", etc., are added. Figures 4 to 13 The accompanying drawings use reference numerals for exemplary embodiments. The following description is substantially limited to those described in the drawings. Figure 2 and Figure 3 Differences in exemplary implementations, wherein regarding maintaining the same components, features, and functions, can be referred to Figure 2 and Figure 3 The description of exemplary implementations in the document.

[0048] Figure 4 and Figure 5An alternative exemplary embodiment of the wheel bearing assembly is shown. Relative to the axial direction 48a of the wheel bearing assembly, the flange 46a of the drive shaft is partially arranged between the attachment region 50a of the hub element 42a and the end side 38a of the bearing ring 26a. Due to the attachment region 50a, the hub element is attached to the bearing ring using a screw 34a. Here, the screw also passes through the flange 46a and securely clamps the flange 46a to the end side 38a. After loosening the screw 34a, the hub element 42a and the brake element 30a can be completely pulled out of the bearing ring 26a together, as the central through-hole 54a of the brake element 30a is large enough to allow the bearing ring 26a and the flange 46a to move completely through the central through-hole 54a, wherein the flange 46a can thus remain attached to the bearing ring 26a. For example, in a completely uninstalled state where neither the brake element nor the flange is connected to any other component, the flange 46a of the drive shaft can move completely through the through-hole 54a. During the removal of brake element 30a, flange 46a is attached to end side 38a of bearing ring 26a by screw 52a. Screw 52a does not penetrate the area of ​​the hub element. Preferably, screw 52a includes a countersunk head and therefore does not protrude axially beyond flange 46a. In an alternative design, the desired orientation of the bearing ring and hub element relative to each other is achieved by the hub element and bearing ring including two threaded holes spaced specifically in the circumferential direction, such that the hub element and bearing have no other threaded holes in the circumferential direction relative to each other. The screw holes form a mounting fastener.

[0049] After removing brake element 30a and installing a new brake element onto hub element 42a, the hub element is reinstalled onto flange 46a and bearing ring 26a. Here, screw 52a plays a crucial role because it is positioned at a point where, in the fully installed state, the circumferential spacing between the two screws 34 is larger than at points circumferentially separated from screw 52a. Furthermore, the diameter of the opening 37a into which screw 52a is screwed in the installed state is smaller than the diameter of the opening 36a into which screw 34a is screwed in the installed state. Figure 13 Thus, the hub element and bearing ring 26a have only a single orientation relative to each other in the circumferential direction, wherein the hub element and bearing ring can be screwed onto each other, such that the maximum possible number of screws 34a pass through the hub element. Figure 12 The only possible orientation for mounting is such that the hub element has a radially inwardly extending protrusion 68a. Figure 5 The radially outwardly extending protrusions 70a of the bearing ring 26a abut against each other over the largest possible surface area. Figure 10This maximizes the contact surface between the hub element and the bearing ring for mutual force transmission and minimizes the possibility of rusting. In other orientations of the bearing ring 26a and the hub element 42a relative to each other, the corresponding contact surface is significantly smaller (…). Figure 11 ).

[0050] Among its individual, uninstalled parts, the wheel bearing assembly forms a kit, and after assembly, all parts of the kit can only be installed when the hub element 42a is oriented in a single orientation relative to the bearing ring 26a in the circumferential direction of the bearing ring.

[0051] exist Figure 6 and Figure 7 The diagram depicts another alternative exemplary embodiment of the wheel bearing assembly. Regarding the shape of the bearing ring 26b, the radial outer surface of the bearing ring 26b is greater than 80% of the outer surface of the truncated cone. The rolling bearings 22b and 24b of the wheel bearing assembly are tapered roller bearings. Here, the tapered roller rows 56b and 58b of the rolling bearings have different dimensions.

[0052] exist Figure 8 , Figure 9 and Figure 14 Alternative exemplary embodiments are depicted. Essentially identical components, features, and functions are generally numbered using the same reference numerals. However, to distinguish these exemplary embodiments, the letters "c" or "d" are added. Figure 8 , Figure 9 and Figure 14 The accompanying drawings use reference numerals for exemplary embodiments. The following description is substantially limited to those relating to... Figure 4 and Figure 5 Differences in exemplary implementations, wherein regarding maintaining the same components, features, and functions, can be referred to Figure 4 and Figure 5 The description of exemplary implementations in the document.

[0053] Figure 8 and Figure 9Another exemplary embodiment of the wheel bearing assembly of the present invention is shown. The wheel bearing assembly includes a component 72c connected to a brake element 30c and a bearing ring 26c. More specifically, component 72c is directly adjacent to the brake element and connected to the bearing ring. Component 72c is an ABS ring having protrusions arranged adjacently in the circumferential direction and extending in the axial direction, which are used by a sensor (not shown) to measure the rotational speed of the bearing ring 26c. Component 72c is spaced close to the brake element and is attached to the bearing ring 26c in the axial direction in a frictional and interference fit. For the last attachment, legs 74c of component 72c abut against the radially inner side of the bearing ring 26c, and legs 74c extend in the axial direction. Regarding the space region 76c between the bearing ring 26c and the brake element 30c, component 72c has a shielding effect on the space region 78c that is axially spaced from the bearing ring 26c and arranged closer to the inner side of the housing than the bearing ring 26c. Therefore, component 72c is also a sealing element.

[0054] exist Figure 14 In an alternative design, screw 52d protrudes axially, while an opening 80d is simultaneously provided in hub element 42d, the protruding portion of screw 52d precisely fitting into opening 80d. Due to this design of the screw and opening, bearing ring 26d and hub element can be mounted in a single orientation relative to each other, thus the screw and opening forming a positioning unit and mounting fixture.
