Description

The invention relates to a wheel bearing assembly with a retaining ring having the features of the preamble of claim 1 and a method for mounting.

Wheel bearings are used to drive on vehicles e.g. Bear hubs against axles. The wheel bearings have in many embodiments at least one rolling bearing. The bearings usually consist of an inner ring, an outer ring and a plurality of rolling elements, which are arranged abrolling between the inner ring and the outer ring. When mounting roller bearings for the wheel bearing, the problem may arise that the rolling bearing is not self-holding and thus must be assembled only from the individual parts during assembly or - if pre-assembled - accidentally disintegrates into its individual parts. In both situations, it is feared that assembly errors occur, for example, too few rolling elements are inserted because the correct number of rolling elements is difficult to control.

An advantage of preassembled modules is in addition to avoiding assembly errors that the time-consuming installation of the rolling element is relocated manufacturer and the industrial customer with the preassembled unit receives a higher quality product.

From the publication DE 10 2012 206 659 A1 , which is probably the closest prior art, a wheel bearing unit is known as a pre-assembled press-fitting rolling bearing unit, which has an outer ring, an inner ring and between the rings load-bearing rollable rolling elements. In the rolling bearing unit, two axially opposite ends of the rolling bearing unit are provided in the pre-assembled state, wherein one of the ring elements snapped over a snap connection in the inner ring and the other ring member is pushed or pressed onto the inner ring. Both ring elements are in contact with the outer ring and secure it. So that the ring elements can run free on the outer ring, they are made of plastic, which abrades in operation at the contact area with the outer ring.

Field of the invention

The invention has for its object to propose a wheel bearing assembly, which constructively implements a new concept for pre-assembled wheel bearings. This object is achieved by a wheel bearing assembly having the features of claim 1 and by a method having the features of claim 10. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and the accompanying drawings.

In the context of the invention, a wheel bearing arrangement is disclosed, which has at least or exactly one rolling bearing. The wheel bearing arrangement is in particular designed to support a hub of a wheel of a vehicle with respect to an axle or the shaft of a wheel with respect to a surrounding construction of the vehicle. The rolling bearing is designed in particular as a radial rolling bearing. The rolling bearing has a first and a second ring, wherein one of the rings is formed as an inner ring and the other of the two rings as an outer ring. The rings are coaxial with each other and arranged concentrically. The rolling bearing further comprises a plurality of rolling elements, which are multi-row but preferably single row, are arranged in the rolling bearing. The rolling elements are rolling between the rings, in particular load-bearing, arranged. This arrangement enables the first ring and the second ring to be rotated relative to each other about a main axis of rotation. The rotation may be a turn or an endless turn.

The rolling bearing comprises a retaining ring, wherein the retaining ring is preferably arranged coaxially to the main axis of rotation. The retaining ring has a fastening portion, preferably a circumferential fastening portion and a securing portion, preferably a circumferential securing portion. Particularly preferred attachment portion and securing portion are each a circumferential portion of the retaining ring.

The attachment portion is fixedly connected to the first ring, wherein the compound may be formed, for example, as a positive connection, such as a snap connection, as a material connection, such as a welded joint, or as a frictional connection. It is also possible that the connection is realized as a combination of the three types of connection. In the case of general embodiments of the invention, the first ring may be the inner ring or the outer ring.

The securing portion of the retaining ring is due to the positioning of the retaining ring by the attachment of the retaining ring on the first ring on the mounting portion aligned so that it can form a shift safety and / or an axial stop for the second ring in the axial direction. Particularly preferably, at least a part of the securing portion is arranged in a region which has an axial projection of the second ring, in particular the end face or the Face of the second ring, overlapped. In particular, the securing section prevents an axially aligned displacement movement of the second ring relative to the first ring in the direction of the retaining ring.

In the context of the invention, it is proposed that the retaining ring has an abutment section, preferably an abutment section revolving around the main axis of rotation, and is designed so that the retaining ring can assume different states depending on an arming force acting on the abutment section in the axial direction:
If no Entsicherungskraft is applied to the contact section, so is the retaining ring, in particular the rolling bearing or the wheel bearing assembly, in a pre-assembly, wherein the securing portion is preferably resiliently applied to the second ring. In the pre-assembly state of the retaining ring thus ensures that the second ring is supported in particular in the axial direction resiliently and can not be moved. Thus, the rolling bearing is present with the retaining ring as a preassembled module, wherein a displacement of the second ring relative to the first ring is prevented at least in an axial direction by the retaining ring. It is possible that another such retaining ring is arranged on the other axial side of the rolling bearing, alternatively, the rolling bearing is structurally designed so that a displacement of the second ring relative to the first ring can be done anyway in one direction.

In a final assembly state, in particular in an operating state of the retaining ring, for example, when the rolling bearing or the wheel bearing assembly is installed when a Entsicherungskraft acts on the abutment portion, the securing portion is lifted from the second ring so that it released, in particular released friction. By applying the Entsicherungskraft thus the rolling bearing and thus the wheel bearing assembly can be transferred from the pre-assembly in the final assembly state, wherein acts in the pre-assembly of the retaining ring as a displacement protection for the second ring and releases the second ring in the final assembly state and thus the friction losses of Rolling bearing keeps low.

The inventive design of the retaining ring is achieved that a loops of retaining rings, as is known for example from the initially published document, is no longer necessary, instead, the frictional engagement between the retaining ring and the second ring, for example. lifted with the installation of the rolling bearing. This implements another concept for implementing a preassembled module, which has advantages in particular during assembly and during commissioning.

In a preferred embodiment of the invention, the lifting off of the securing portion from the second ring is effected by a pivoting and / or rocker mechanism, wherein the abutment portion and the securing portion can be rocked and / or pivoted via the attachment portion.

Considering a longitudinal section along the main axis of rotation through the retaining ring, the abutment portion faces the attachment portion in a radial direction and the securing portion opposite the attachment portion in the other radial direction. Upon actuation of the Entsicherungskraft on the contact portion thus the securing portion is pivoted about the mounting portion. In particular, the mounting portion forms a rocker stand and abutment portion and securing portion a rocker connection, which can rock relative to the rocker stand. In the case of the rockers, all sections can also warp due to the arming force, so that it can be a superposition of the rocking and / or pivoting movement with a linear movement.

In a preferred embodiment of the invention, the rolling bearing is designed as an angular contact bearing. In the form of the oblique bearing this has the advantage that the second ring can move relative to the first ring only in one direction, wherein the retaining ring is arranged so that this displacement direction is positively locked. Particularly preferably, the rolling bearing is designed as a tapered roller bearing, wherein the retaining ring is arranged in particular on the small radius of the tapered roller bearing. Thus, such a retaining ring is sufficient to realize a captive for the second ring. Further, it is preferably claimed that the first ring is formed as the inner ring and the second ring as the outer ring, so that the fixing portion is in contact with the inner ring and the securing portion is in contact with the outer ring.

In a particularly preferred embodiment, the Entsicherungskraft is designed as an axial clamping force for the first ring, in particular for the inner ring. Thus, the retaining ring assumes a double function and on the one hand as captive for the second ring during assembly and / or in the pre-assembled state and the second for introducing an axial clamping force in the first ring, in particular in the inner ring. But also the clamping force takes on a dual function, since this one for bracing the wheel bearing assembly and the other for applying the Entsicherungskraft is used. The bracing force is preferably greater than 20KN, in particular greater than 30KN and / or is preferably less than 300Kn, in particular less than 200KN. It can be adjusted by the structural design of the retaining ring acting on the bearing, resulting from the clamping force biasing force and / or bearing clearance, for example, by varying the wall thickness or by varying the length of the spacer section.

Generally and in particular in this embodiment, it is particularly preferred that the retaining ring is made of a metallic material, in particular steel, in order to be able to transfer the tensioning force on the one hand and to have sufficient elasticity on the other hand.

Structurally considered, the structure of the retaining ring is particularly preferably realized so that in one or the longitudinal section along the main axis of rotation of the attachment portion comprises a mounting leg, the securing portion comprises a securing leg and the abutment portion an abutment leg, wherein the mounting leg and the securing leg are connected to each other via the plant leg. A free end region of the securing leg forms the displacement safeguard and / or the axial stop for the second ring, in particular for the outer ring. A region facing the first ring, in particular an intermediate region or an end region, of the fastening section is fixedly connected to the first ring.

In principle, the rolling bearing can be filled with grease, the retaining ring forming an end-side closure of the rolling body space and securing the grease. In particular, in the embodiment, wherein the fastening legs, securing legs and bearing limbs are connected to each other, an additional volume for the grease is provided.

Particularly preferred in the longitudinal section of the securing leg and the mounting legs are rectilinearly extending, in particular aligned parallel to each other. In particular, the attachment portion and / or the securing portion each form a cone-shaped annular region, wherein the large radius of the cone abut the rolling bearing, in particular on the first and the second ring. By the rectified course and the cover by the plant leg a very large volume of fat is achieved and at the same time built a framework, which allows the rocker mechanism.

In a preferred embodiment of the invention, the attachment portion comprises a distance range, wherein the distance range acts as an axial stop for the abutment portion in the direction of the first ring. In the longitudinal section, the distance region is formed as a spacer leg. With the distance range, in particular spacer legs, it is achieved that the contact portion can not be pressed too close to the first ring due to a Entsicherungskraft, in particular a clamping force, since the distance range blocks this shift as an axial stop. Furthermore, it is achieved that is lifted by the application of the clamping force on the one hand, the securing portion of the second ring and on the other hand by moving the abutment portion in the axial stop any spring effects in the force path of the clamping force can be taken out. Particularly preferably, spacer legs and fastening legs are formed in longitudinal section as a common leg.

In a preferred embodiment of the invention, the rolling bearing can be arranged in any surrounding construction or on a hub, wherein the surrounding structure forms part of the wheel bearing arrangement. In particular, the rolling bearing may be arranged so that it is supported with the abutment portion of the retaining ring on the surrounding structure, so that the final assembly state is reached.

In a particularly preferred embodiment of the invention, the wheel bearing assembly on another such rolling bearing with another such retaining ring. The rolling bearing with the retaining ring and the other rolling bearing with the other retaining ring can be identical, preferably in a symmetrical manner to each other, be formed. However, it is also possible that the rolling bearing with the retaining rings are formed differently from each other, each of the bearings can take any of the variations shown above. It is particularly preferred that the rolling bearing and the further rolling bearing are arranged so that the retaining ring and the further retaining ring facing each other. In this way, a clamping force, which clamps the rolling bearings together, are transmitted via the retaining rings between the rolling bearings as and used as the Entsicherungskraft.

It is possible that the retaining rings are arranged directly contacting, so that contact the contact portions in a joint area. In a possible alternative of the invention, a spacer is arranged between the retaining rings, wherein the spacer is supported on the retaining rings, in particular on the abutment portions of the retaining rings, in particular exclusively supported in the axial direction. It is possible that the spacer is just hollow cylinder-shaped and thus connects the two bearings with a constant diameter. Alternatively to this the spacer is stepped, conical or diameter varying, so that at one end of the spacer with a first diameter and at the other end with a second diameter rests against the respective retaining ring.

In one possible development of the invention, the abutment sections each have a centering contour for the spacer. For example, the centering contour is realized as a leg region formed at right angles in a longitudinal section, so that the spacer abuts in the axial direction and is guided in the radial direction.

Another object of the invention relates to a method for mounting the wheel bearing assembly, as described above or according to one of the aforementioned claims, wherein the rolling bearing with the retaining ring, starting from a pre-assembly, wherein the securing portion is resiliently applied to the second ring in a final assembly state , In particular, an operating state is transferred, wherein a Entsicherungskraft acts on the abutment portion, so that the securing portion is lifted from the second ring. Particularly preferably, the wheel bearing assembly is transferred in a final assembly of the pre-assembly in the final assembly state.

The 1 shows in a schematic longitudinal section along a main axis of rotation H a wheel bearing assembly 1 as an embodiment of the invention. The wheel bearing arrangement 1 is designed for use in a vehicle, in particular a truck or passenger car. The wheel bearing arrangement 1 has two rolling bearings 2a , B, which are arranged coaxially with each other about the main axis of rotation H. The rolling bearings 2a , B are each designed as an angular contact bearing, in this example as a tapered roller bearing, Each of the rolling bearings 2a , b has an inner ring 3a , b and an outer ring 4a , b on, being between inner ring 3a , b and outer ring 4a , b a plurality of rolling elements 5a , b, which are formed as tapered rollers, are distributed in the direction of rotation about the main axis of rotation H. The rolling elements 5a , Define by their axes of rotation at their free ends in each case a pitch circle diameter, wherein the rolling bearings 2a , B are arranged so that the pitch circle diameter with the small radius facing each other. The inner rings 3a , b are executed separately to each other, the outer rings 4a , b are also formed separately from each other.

Each of the rolling bearings 2a , b is a retaining ring 6a or b associated with the retaining rings 6a , b on the respective other rolling bearing 2 B , a facing side of the bearings 2a , b are arranged. Each of the retaining rings 6a , b has a mounting portion 7a , b, a securing section 8a , b and an investment section 9a , b on. In the longitudinal section shown are the attachment portion 7a , b respectively as a fixing leg, the securing portion 8a , b respectively as a securing leg and the abutment section 9a , B each formed as a plant leg, wherein the plant leg or the contact portion 9a , b the securing leg or the securing portion 8a , b with the associated attachment leg or attachment portion 7a , b connects.

The attachment section 7a is with the inner ring 3a connected via a fixed connection 10a. The attachment section 7b is with the inner ring 3b over a fixed connection 10b connected, both connections 10a , B are each formed as a welded joint. The attachment section 7a , B is formed in the coarse form as a circumferential cone section, wherein the cone diameter on the inner ring 3a respectively 3b larger than the cone diameter at the opposite end of the attachment portion 7a respectively 7b is.

The security section 8a or b is formed in this example in each case as a cone portion, wherein the cone diameter on the outer ring 4a respectively 4b larger than the cone diameter at the attachment portion 7a or b is. The investment section 9a , b is also formed as a cone portion, wherein the cone diameter at the securing portion 8a , b greater than at the attachment portion 7a , B is formed and the cone portion, starting from the associated inner ring 3a , b or outer ring 4a , b is formed rising.

In the longitudinal section form the securing portion 8a , b, attachment section 9a , b and attachment section 7a , b of each retaining ring 6a , b a particular shifted U-shaped receiving space 11a , b, which is optionally filled with a lubricant, in particular with a lubricating grease.

The investment sections 9a , b collide in a joint area 12 to each other, with the joint area 12 the attachment sections 7a , b radially further inside than the connections 10a , b. Radially outward increases starting from the joint area 12 the distance between the plant sections 9a , b. The attachment sections 7a , b are about the connections 10a , b at the front of the inner rings 3a respectively 3b attached.

Functionally considered is in the 1 a pre-assembly state of the retaining rings 6a , b or the rolling bearings 2a , B or the wheel bearing assembly 1 shown, with the fuse sections 8a , b with their free end regions resiliently on the outer rings 4a respectively 4b , in particular rest against the end surfaces or end faces. Through this system form the security sections 8a , b a displacement protection of the outer rings 4a , b to each other. In particular, these form an axial stop for the outer rings 4a , b in this direction. In the opposite direction, the outer rings 4a , b due to the increasing pitch diameter of the axes of rotation of the rolling elements 5a , b also can not be moved, so the rolling bearings 2a , b each form a captive and / or self-holding assembly. Such an assembly, for example, can be kept in stock as a spare part and does not have to be assembled from individual parts as needed.

Like in the 2 is shown in a final assembly of the wheel bearing assembly 1 , in particular the rolling bearings 2a , b, in a surrounding construction on the inner rings 3a , b applied a tensioning force F acting in the axial direction. By the clamping force F, the retaining rings 5a , b pushed together and in the joint area 12 there is a Entsicherungskraft as part of the clamping force F on the plant sections 9a , b in the joint area 12 acts in the axial direction. By Entsicherungskraft be considered in the longitudinal section, the securing sections 8a , b around the attachment sections 7a , b and the connections 10a , b panned. Model can also be said that each of the fuse section 8a and the investment section 9a around the attachment section 7a teeters or pans or the securing section 8b and the investment section 9b around the attachment section 7b teeters or pans. As a result of the swing or the rocking raise the fuse sections 8a , b from the end face of the outer ring 4a , b, so that they are contactless. With the assembly or with the transition from the pre-assembly state into a final assembly state, it is thus achieved that the anti-displacement device is released and the outer rings 4a , b relative to the retaining rings 6a , B can rotate smoothly.

In addition, the clamping force F on the retaining rings 6a , b, in more detail about the attachment portion 7a , b and the investment section 9a , b, in the joint area 12 between the inner ring 3a , b transfer. Thus take over the retaining rings 6a , b next to the function of the anti-slip device for the outer rings 4a , b before assembly after assembly the task, between the inner rings 3a , b to transmit the tensioning force F.

In the 3 is a further embodiment of the invention to see, wherein the same reference numerals the same areas or parts of the wheel bearing assembly 1 so that only the differences are discussed below. In contrast to the embodiment in the 1 and 2 has the embodiment in the 3 a positive connection 10c , d between the attachment section 7a , b and the inner ring 3a , b on. The positive connection 10c , we on the side of the rolling bearing 2a , B by a circumferential edge of the inner ring 3a , b and on the side of the retaining rings 6a , B formed by a hollow cylindrical portion and an abutment shoulder, wherein the retaining ring 6a , b in a simple way on the inner ring 3a , b is attached and with the contact shoulder form-fitting on the front side or end face of the inner ring 3a , b is applied. The positive connection thus takes place when the retaining ring 6a , B in the axial direction to the associated inner ring 3a , b is pushed. In the opposite direction is in this embodiment, a frictional connection.

In the 4 is a development of the wheel bearing assembly 1 shown in the preceding figures, wherein the attachment portion 7a also a distance range 13a , b, which is formed in the longitudinal section respectively as a spacer leg. The distance range 13a , B is designed as a aligned in the axial direction to the main axis of rotation H ring portion whose free end an axial stop for the abutment portion 9a respectively 9b in the same radial position as in the joint area 12 forms. The distance range 13a , B is designed so that upon compression of the abutment section 9a , b in the direction of the associated inner ring 3a , b the investment section 9a , b or a first portion of the attachment portion 7a , b, in the axial direction of the distance range 13a , b runs up and prevents further displacement. By the distance range 13a , b is achieved that the retaining rings 5a , B can not compress arbitrarily far in the axial direction, but are limited in the travel. In addition, it is possible by the distance range 13a , b in case of application of the clamping force F, the connection between the inner rings 3a , b feather-free implement and thereby the wheel bearing assembly 1 stiff to design.

In the 5 is shown a process step for disassembly, wherein a hub 14 as part of a surrounding construction with the outer rings 4a , b and a shaft or axle (not shown) with the inner rings 3a , b are connected. By moving the hub 14 in a disassembly direction in this example to the left to the wheel bearing assembly 1 be deducted from the shaft or axis. Through the retaining ring 6b It is possible that the disassembly force on the outer ring 4b , the retaining ring 6b on the inner ring 3a is transmitted, so that the outer ring 4b over the retaining ring 6b the inner ring 3b in the dismounting direction entrains. In this type of disassembly, it is particularly advantageous that the retaining ring 6b on the inner ring 3b is welded, so that also stronger tensile forces from the retaining ring 6b on the inner ring 3b can be transmitted.

In the 6 a further embodiment is shown, which differs from the embodiment in the 1 this distinguishes that between the plant sections 9a , b a spacer 16 , which is formed in this example as a straight sleeve, is arranged. The free ends of the spacer 16 lie in the corresponding areas of the joint area 12 the retaining rings 5a , b, which thereby enters a joint area 12a , b divides.

In the 7 is the embodiment in the 4 along with the spacers 16 in the 6 shown.

In the 8th a modification of the preceding figure is shown, wherein the retaining rings 6a , b in the joint area 12a , b each have a centering contour 17a , b, so that the spacer 16 on the one hand can positively support in the axial direction and is centered on the other in the radial direction to the outside. The centering contour 17a , b is formed as a circumferential groove or a circumferential shoulder.

In the 9 is a variant of the embodiment in the 8th shown, the two rolling bearings 2a , B a different pitch circle diameter or their inner rings 3a , B have a significantly different inner diameter. Even with different pitch diameters or inner diameters, the bearings 2a , b the wheel bearing assembly 1 form, wherein the clamping force or Entsicherungskraft in this example again on a spacer 16 is transferred, which, however, assumes a conical shape in this example.
