Description

The invention relates to a braking system for a motor vehicle. In addition, another aspect of the invention relates to the manufacture of such a braking system as will be discussed in more detail below.

The brake system comprises a friction ring and a brake pot, the brake pot being designed for fastening the friction ring to a motor vehicle axle. The friction ring and the brake cup are arranged coaxially to a brake system axis. The friction ring comprises two friction disks and an axle opening formed coaxially to the brake system axis for the passage of a motor vehicle axle to which in particular the friction ring is to be fastened by means of the brake cup. Each of the two friction disks each has an axle opening, which in particular are aligned coaxially to one another and which form the axle opening. In each of the two friction disks, a respective edge section of the same surrounds the respective axis opening in the circumferential direction and, in particular, the respective edge section surrounding the axis opening defines a radial extension of this axis opening. One of the edge sections has a toothing which is designed, in particular, to be oriented radially inward.

The brake cup comprises a mounting base for mounting on a motor vehicle axle and a casing wall designed to extend away from the mounting base in the axial direction, the casing wall being provided with a toothing corresponding to the toothing of the one edge section. The brake cup has a large number of holding elements on the jacket wall.

The object on which the present invention is based is to improve braking systems of the generic type.

According to the invention, this object is achieved in a brake system of the type mentioned in that holding elements of a first subset of the plurality of holding elements are arranged axially between the two friction disks and from there engage the friction disk having the toothing and holding elements of a second subset of the plurality of holding elements on one attack axially outwardly oriented flat side of the friction disk having the toothing and that the brake cup and the friction ring are held against one another without play at least in the direction axial to the brake system axis by the large number of holding elements.

In particular, the holding elements for holding the friction ring are thus formed on the one friction disk having the toothing.

One of the advantages of the invention can be seen in the fact that the holding elements on the friction disk having the toothing engage on the one hand from an area axially arranged between the two friction disks and on the other hand engage on their axially outwardly oriented flat side and thus the friction ring securely through the plurality of holding elements can be held and thus stably attached to the brake pot.

In addition, free installation space is available in particular in the axial area between the two friction disks and on the axially outwardly oriented flat side of the friction disk, so that the holding elements can be arranged engaging the friction disk in a structurally simple and cost-effective manner. It is particularly favorable that this free installation space is already available and therefore no special receptacles need to be formed for the holding elements.

In particular, an advantage of the solution according to the invention can be seen in the fact that the brake cup and the friction ring are held together without play, at least in the axial direction to the brake system axis, and thereby at least reduce or even prevent wobbling of the friction ring and possibly associated damage to the brake system during operation of the brake system can be.

So far, no further details have been given on the design of the holding elements.

In particular, at least some of the holding elements are designed as axial stops.

In advantageous embodiments it is provided that at least some holding elements are designed as holding tongues. In particular, the holding tongues extend from a foot area to a tongue tip. It is preferably provided that the respective holding tongues are arranged with their foot area on the jacket wall and extend from this up to a free end area, the tongue tip being formed in particular in the free end area.

For example, one advantage of this is that the holding tongues can be easily shaped, for example can be shaped out of the jacket wall, and can be advantageously arranged on the friction disk without play, in particular pressed on.

In particular, the free end region of the holding tongues is arranged at a distance from the jacket wall.

It is particularly favorable if the retaining tongues rest against the friction ring without play, at least in sections, and in particular rest against the friction disk having the toothing without play.

This achieves, in particular, that the holding tongues hold the friction ring in a stable manner with their section resting against the friction ring without play and, in particular, even with high loads on the brake system, wobbling of the friction ring is at least reduced or even substantially prevented. In addition, the holding tongues in particular can be pressed in a favorable manner against the friction ring, in particular against the friction disk having the toothing, so that a section of the holding tongues rests against it without play. The partially play-free application of the retaining tongues is also advantageous, since surface inaccuracies on the friction ring can be compensated for and thus the friction ring can have greater tolerances, which means that it can be manufactured more cost-effectively.

For example, in at least some of the retaining tongues, a section between the foot area and the tongue tip, in particular between the foot area and the free end area, rests on the friction disk without play. In particular, this variant enables simple and therefore cost-effective reshaping of the holding tongues.

As an alternative or in addition, it is particularly advantageous if the free end region of the retaining tongues rest against the friction disk without play. For example, the free end area offers a favorable contact surface in order to keep the friction disk free of axial play. Preferably, the free end area also offers a contact surface that is extended in the radial direction, so that a thermal distortion of the friction disc when heated during operation and when it cools afterwards can be compensated for by the adjacent end area and axial play-free retention is then also provided. For example, the free end area can also be molded onto the friction disk in a favorable manner, so that its permitted tolerances can be increased.

It is particularly favorable if the retaining tongues extend at least in sections at an angle to the radial direction and / or at least approximately in the radial direction away from the jacket wall. In particular, the holding tongues extend, starting from the jacket wall, essentially radially inwardly away from the latter. For example, the holding tongues thus form holding elements projecting radially away from the jacket wall, with which the friction disk can be held in a stable manner and, in particular, axially free of play, in a favorable manner. For example, the holding tongue extends away from the jacket wall with a section extending from the foot region at an angle to the radial direction.

In some preferred embodiments it is provided that the retaining tongue extends essentially up to the free end region at an angle to the radial direction. In other advantageous embodiments, at least the free end region of the holding tongues extends at least approximately in the radial direction and thus preferably offers a substantially axially oriented support for the friction disk by which it is held in a stable manner and, in particular, is kept free of axial play. For example, a section of the retaining tongues that extends at least approximately in the radial direction also offers a sufficiently large support for the friction disk in the radial direction, so that in particular a radial distortion of the same, for example due to thermal expansion, can be compensated for.

The retaining tongues are preferably designed to be slightly resilient, so that, on the one hand, the friction disc can be expanded axially by heating it during operation and, on the other hand, after it has cooled down, the resiliently designed retaining tongue compensates for the again decreasing axial thickness of the friction disc and continues to provide a stable and secure hold guaranteed by the friction disc.

In particular, the holding tongues are arranged at a respective transition area on the jacket wall.

It is particularly favorable if, in at least several of the holding tongues, the respective transition area is designed to run essentially in the direction of rotation. For example, such a transition area offers a stable connection of the holding tongues to the jacket wall, in particular in the case of holding tongues extending obliquely or at least approximately in the radial direction.

It is particularly favorable if the respective holding tongue extends at least approximately perpendicular to the direction of rotation away from its transition region, in order to hold the friction disk stable, for example.

In different embodiments, the retaining tongues are molded onto the casing wall in a wide variety of ways.

In particularly advantageous embodiments, it is provided that a wall segment of the jacket wall merges into a corresponding holding tongue in a respective transition area. It is particularly favorable if the retaining tongue is formed in one piece with the jacket wall and the wall segment merges in one piece into the corresponding retaining tongue in the transition region. In particular, this forms a structurally simple design for a stable connection of the retaining tongues to the jacket wall.

In particularly favorable embodiments, it is provided that at least some of the holding elements are designed in the manner of a bridge. For example, the bridge-like holding elements provide an axial stop for the friction disk and thus hold the friction disk in a stable manner in the axial direction. For example, the bridge-like holding elements also offer an axial stop and thus preferably facilitate positioning of the friction ring with the friction disk relative to the brake cup during assembly.

In particular, it is provided that the bridge-like holding elements each essentially bridge a recess in the teeth of the shell wall. Thus, for example, the bridge-like holding elements grip over teeth of the toothed friction disk and offer a secure axial hold in the area of the intermeshing teeth and teeth.

In particular, it is provided that the bridge-like holding elements comprise a bridge part. The respective bridge part is preferably designed to be essentially elongated in the direction of rotation. A stable holding element with a generous support surface is preferably provided by the elongated extension in the direction of rotation.

It is particularly preferred if the bridge part is arranged on the jacket wall with connecting parts arranged opposite one another in the circumferential direction. In particular, these connecting parts are arranged essentially on end regions of the bridge part arranged opposite one another in the circumferential direction and extend from these to the jacket wall, on which they are also arranged. In this case, the connecting parts preferably extend essentially in the radial direction or at an angle to the radial direction, so that the bridge part protrudes radially inward in front of the jacket wall.

For example, by arranging the bridge part on both sides through the connecting parts, a stable arrangement is achieved, so that the friction disk is held securely by the bridge-like holding element even when the friction disk is subjected to heavy loads.

It when the bridge part is arranged on teeth of the teeth of the shell wall is particularly favorable. In particular, the respective bridge part is arranged on adjacent teeth with opposite ends and bridges the recess between the adjacent teeth. For example, the bridge part thus engages a tooth of the friction disk and thus offers a stable hold for the friction disk in the area of the intermeshing toothing and toothing of the shell wall. In particular, the bridge part is arranged with a respective connecting part on a corresponding tooth. In favorable variants, at least some of the bridge parts are arranged on radially protruding tooth tips. It is also favorable if at least some of the bridge parts are arranged on a tooth flank of the corresponding tooth.

With regard to the arrangement of the holding elements, no further details have been given so far.

In particularly advantageous embodiments, it is provided that the holding elements of the first subset are designed as holding tongues. In particular, they then have one or more of the features explained above in connection with the retaining tongues.

This is advantageous, for example, since installation space is available between the friction disks in order to bend retaining element sections on the brake cup in an undeformed state after the brake cup has been inserted to form the retaining tongues.

It is particularly favorable if the holding elements, which are designed as holding tongues, are arranged with their foot region on a wall end region axially opposite the mounting base.

In particular, the jacket wall can then lie essentially over the entire surface of the edge section and the holding tongues arranged on the wall end region encompass the friction disk in order to hold the same in a stable manner.

It is particularly advantageous if the holding tongues protrude axially beyond the wall end area. For example, the holding tongues can then encompass the edge section for holding and the jacket wall does not protrude axially beyond the edge section, so that, for example, cooling channels arranged between the friction disks are not covered by the jacket wall and, in addition to being held securely, efficient cooling also takes place via the cooling channels can.

As an alternative or in addition, in some advantageous embodiments it is provided that the holding elements of the second subset are designed as holding tongues. For example, thereby a secure axial holding in the area of the outside of the friction ring, which is formed by the flat side of the friction disk, enables.

In some favorable embodiments it is provided that at least some of the holding elements designed as holding tongues are punched out of the jacket wall. In particular, this enables a structurally simple design of the holding tongues. This design is particularly advantageous in the case of holding tongues arranged in an axially central region of the jacket wall, since these can be shaped out of the jacket wall in a structurally simple manner. The axial middle area is arranged axially between the wall end area and the mounting base.

In other particularly advantageous embodiments, it is provided that the holding elements of the second subset are designed in the manner of a bridge and in particular have one or more of the features discussed above in connection with the holding elements designed in the manner of a bridge. This is particularly favorable in order to provide a stable and secure axial hold on the outside of the friction ring by means of the bridge-like holding elements.

As an alternative or in addition, in favorable embodiments it is provided that the holding elements of the first subset are designed in the manner of a bridge. In particular, a stable holding is thereby provided by the bridge-like holding elements between the friction disks.

In advantageous embodiments it is provided that the bridge-like holding elements are punched out of the jacket wall. In particular, this is favorable both for holding elements of the first subset and for holding elements of the second subset. A structurally simple way of producing the same is thus provided for the bridge-like holding elements.

In particular, it is provided that the bridge part is punched out of a wall segment delimiting a recess and the connecting parts are punched out of tooth flanks adjoining this wall segment, which are in particular formed by intermediate segments of the shell wall.

For example, in some favorable embodiments it is provided that some holding elements of both the first and the second subset are designed as holding tongues and other holding elements of both the first and the second subset are designed in the manner of a bridge. Thus, the advantages of the respective type of construction unfold both on the axially outwardly oriented flat side of the friction disk and on a side of the friction disk facing the other friction disk, on which the other holding elements act.

In other particularly advantageous embodiments, it is provided that at least most, in particular all, of the holding elements of a subset are essentially the same, that is to say in particular in the form of a bridge or as holding tongues. This offers a structurally simpler solution and is easier to implement during assembly and thus more cost-effective to achieve.

As an alternative or in addition, the above-mentioned object is also achieved according to the invention in that at most one holding element is arranged for each recess of the teeth in the jacket wall.

For example, this offers a cost-effective solution, since the retaining elements, in particular as explained above, ensure that the friction ring is held securely and since at most one retaining element is provided for each recess, this solution is easier to implement in terms of assembly. In particular, in this solution, the jacket wall is also made stable, since at most one holding element is punched out of this or arranged on it for each recess and thus the jacket wall is not excessively stressed by the holding elements.

For example, in this embodiment, exactly one holding element is arranged on each recess. A technical solution that is both inexpensive and stable is preferably provided with a secure axial hold between the friction ring and the brake cup.

Alternatively or additionally, the above-mentioned object is also achieved in that the holding elements of the first subset, which are arranged between the two friction disks and from there engage the friction disk having the toothing, and the holding elements of the second subset, which are arranged on an axially outwardly oriented flat side attack the friction disc having the toothing, are arranged alternately in the direction of rotation. The holding elements of the first and / or second subset preferably have one or more of the features explained above in connection with them.

In particular, one of the advantages of this solution can be seen in the fact that the alternating arrangement of the holding elements of the first subset and the holding elements of the second subset holds the friction disk with the toothing evenly axially from both sides and thus provides a secure hold.

It is preferably provided that in the case of adjacent recesses to a recess with a holding element of the first subset, holding elements of the second subset are arranged and vice versa.

As an alternative or in addition, it is particularly advantageous if, in the case of recesses with a holding element, which is designed as a holding tongue, no further holding element is arranged. In particular, this enables the retaining tongue to be axially acted upon and folded over and there is no counter-stop directly opposite axially, so that with sufficient loading the friction disc can be axially clamped by means of the holding tongue and thus a stable, play-free axial hold is provided.

In particularly advantageous embodiments, it is provided that essentially no holding elements are arranged on the teeth of the teeth of the jacket wall. In particular, no holding elements are arranged on the radially protruding tooth tips. In some favorable embodiments, holding elements are arranged on the tooth flanks which run radially at an angle to the recess.

With regard to the further design of the brake cup, no further details have been given so far.

It is particularly favorable if the jacket wall of the brake cup is designed to be essentially continuous at least in an area in which the toothed friction disk is arranged radially to the jacket wall. In particular, this means that the jacket wall in the contact area is designed to be continuous and stable, so that torque can be transmitted safely and even under high loads.

It is particularly preferred if the jacket wall, in particular the continuously formed jacket wall, rests radially on the edge section with the toothing essentially over the entire surface.

In advantageous embodiments, it is provided that the jacket wall is formed by individual wall segments, in particular in one piece. Preferably, the wall segments are alternately offset in the direction of rotation in the radial direction and thus in particular form the teeth of the shell wall. For example, the wall segments arranged radially offset from one another are connected to one another by intermediate segments running in the radial direction or at an angle to this.

In particular, the wall segments arranged radially inward form the teeth of the teeth and the radially recessed wall segments delimit the recesses between the teeth and the intermediate segments between these wall segments arranged offset form tooth flanks of the teeth.

In addition, it is provided in particular that the mounting base of the brake pot has an axial opening for the passage of the vehicle axle into which the brake pot is to be fastened.

In different embodiments, the brake cup is made from different materials.

However, it is particularly favorable if the brake cup is made of a metallic material, in particular is made of sheet metal. This offers an inexpensive and stable solution.

With regard to the design of the friction ring, no detailed information has been given so far.

In particular, at least the edge section with the toothing, preferably both edge sections, is essentially solid. On the one hand, this enables them to be manufactured in a structurally simple manner and, on the other hand, it increases the stability of the same.

In particular, the edge sections with an edge surface delimit their axis opening in the radial direction. In particular, this edge surface is oriented axially inward. In the case of the edge section with the toothing, the edge surface runs in the direction of rotation corresponding to the toothing and extends axially between the two flat sides of the friction disk.

It is particularly favorable if the edge section with the toothing has an edge surface which is designed to run axially essentially continuously. This edge surface thus extends axially from the one flat side to the other flat side, essentially as a straight edge surface.

A large-area edge surface is thus preferably provided for the contact with the jacket wall of the brake cup, so that the jacket wall and the friction disk lie against one another over the largest possible area, thus enabling particularly effective torque transmission and a stable construction of the connection. In addition, such a continuously running edge surface is easy to manufacture and is therefore inexpensive to manufacture.

Struts, in particular, are provided axially between the two friction disks and connect the two friction disks to one another.

Cooling channels which point radially outward and which are defined in particular by the struts are preferably provided between the friction disks.

It is particularly favorable if the two friction disks, and in particular with the struts between them, are designed in one piece. In particular, the friction ring is designed to be particularly stable.

In the case of different variants, the friction ring is made from a wide variety of materials.

In some favorable embodiments, the friction ring is made from a ceramic material, in particular from a ceramic fiber composite material.

In other advantageous embodiments, the friction ring is made from a metallic material. In particular, the friction ring is a cast component, preferably made of cast iron.

Another aspect of the invention relates to a brake system for motor vehicles comprising a friction ring which can be fastened to a vehicle axle by means of a brake pot and defines a brake system axis. In addition, the friction ring comprises two friction disks, each with an axle opening, and the two axle openings form an axle opening for the implementation of a motor vehicle axle. In particular, it is provided that, in one of the two friction disks, an edge section, which surrounds its axis opening in a closed manner in the direction of rotation, has a toothing. It is also provided that the axis opening of the other of the two friction disks has a larger diameter in the radial direction than the axis opening with the toothed edge section.

An advantage of this aspect of the solution according to the invention is that the axis opening of the other of the two friction disks has a larger diameter than the axis opening with the toothed edge section, on which in particular the brake pot is to be arranged, and that a sliding tool is easy due to the larger axis opening can be passed through during the assembly of the brake system, for example in order to reshape holding element sections of a jacket wall of the brake pot into holding elements.

In particular, it is therefore provided that the toothed edge section has an exposed area which is not covered in the axial direction by the other of the two friction disks. This has the advantage, for example, that slide elements of the slide tool can be moved essentially unhindered to this exposed area in the axial direction and, in particular, can transform holding element sections into holding elements by applying an axial force.

For example, it is provided that a radial extension of the larger axis opening measured from the brake system axis is greater than a radial distance between the tooth tips and the brake system axis by at least half the length of the radial extension of the teeth. In particular, the tooth tips and, proceeding from these, the teeth are then up to about half their radial extent in the exposed area.

It is particularly advantageous if the radial extent of the larger axle opening, measured from the brake system axis, is greater than a radial distance, measured from the brake system axis, from the recess backs arranged between the teeth or is essentially the same size. In particular, the teeth of the toothed edge section are then essentially in the exposed area. For example, sufficient free space is thus provided for the sliding tool to deform the holding element sections into holding elements.

It is particularly preferred if the radial extent of the larger axis opening is greater than the radial distance between the recess backs by at least approximately the length of the radial extent of the teeth. In particular, the teeth as well as an adjoining ring section then lie with at least approximately the same radial extent in the exposed area. It is particularly advantageous that space is again provided for the sliding tool and for reshaping the holding element sections.

In this aspect of the invention, the brake system preferably also has one or more of the further features explained above.

The invention also relates to a method for producing a brake system for a motor vehicle, in particular for producing a brake system with one or more of the features explained above.

The method comprises the provision of a friction ring and a brake pot, which are arranged essentially coaxially to a brake system axis. The friction ring comprises two friction disks, each with an axis opening. The axis openings form a coaxial to Brake system axis trained axle opening for the implementation of a motor vehicle axle. The brake cup comprises a mounting base for mounting on a motor vehicle axle and a jacket wall designed to extend away from the mounting base in the axial direction.

The method further comprises the step that a plurality of holding elements are formed from the jacket wall. For at least partial arrangement of the jacket wall in the axle opening, the brake cup and the friction ring are brought together in the axial direction during the process until the molded holding elements are in contact with a first flat side of one of the friction disks, so that at least a section of the jacket wall is arranged in the axis opening of one friction disk .

The object on which this aspect of the invention is based is to improve a method for producing a brake system, in particular to make it simple and inexpensive, and preferably to provide a stable connection between the brake pot and the friction ring.

According to the invention, this aspect is achieved in the method of the type mentioned at the outset in that, after the step of bringing the brake pot and the friction ring together until the shaped holding elements are in contact with a first flat side of one of the friction disks, further holding elements are shaped out of the brake pot, the shaping takes place in that holding element sections of the jacket wall are deformed outward in the radial direction by a substantially axial displacement of a slide tool and thus form the further holding elements.

One of the advantages of this aspect of the solution according to the invention can be seen in the fact that the essentially axial displacement of the sliding tool, which is easy to accomplish, reshapes the holding element sections radially outwards and forms them into the holding elements. Thus, in particular, a simple to implement and thus cost-effective method for reshaping the further holding elements is provided and the brake cup and the friction ring are preferably held together in a stable manner by the further holding elements.

Alternatively or in addition, the above-mentioned object is also achieved according to the invention in that, in a method of the type mentioned at the beginning, retaining element sections of the jacket wall are formed into further retaining elements and, for at least axially play-free holding of the friction ring, are placed on a flat side of the one friction disk axially opposite the first flat side will.

In particular, it is advantageous that the further holding elements are placed without play on the one friction disk, namely on the flat side axially opposite the first flat side, so that this friction disk is held axially free of play between holding elements formed from the jacket wall and thus a stable connection between the brake cup and the friction ring is made.

It is particularly preferred if the further holding elements are reshaped outwardly in the radial direction by an essentially axial displacement of the sliding tool and are placed on the flat side axially opposite the first flat side without play. In particular, the stable connection is then provided in a simple method.

It is particularly favorable if the holding element sections are reshaped in a force-controlled manner. This enables, in particular, a reshaping adapted to the local conditions of the flat side of the friction disk, so that the friction disk can be manufactured with larger tolerances and these are compensated for by the force-controlled reshaping of the holding element sections and in particular the holding elements formed from the holding sections despite the larger permitted tolerances in the Friction disk can be applied to this without play. Thus, because of the larger tolerances allowed, the method is more cost-effective and, nevertheless, a clean application of the holding elements to the friction disk for secure holding is made possible.

With regard to the sliding tool used, no further details have been given so far.

For reshaping the holding element sections, a sliding tool is preferably used which comprises a lifting element to provide an axial stroke and a plurality of slide elements coupled to the lifting element for reshaping the holding element sections.

Thus, an axial stroke is preferably provided by the lifting element and the holding element sections can be reshaped by the multiple slide elements coupled to it.

It is particularly favorable if the sliding tool comprises one sliding element for each holding element section to be reshaped. Furthermore, it is provided that each holding element section to be reshaped is reshaped individually by a respective slide element. In particular, this is favorable because the individual reshaping of the holding element sections by a respective one Slider element larger tolerances are permitted for the friction disc. This is because the individual reshaping of each of the holding element sections by a respective slide element allows reshaping to take place in accordance with the local conditions of the friction disk and greater tolerances to be compensated.

It is particularly advantageous if the plurality of slide elements are force-coupled to the lifting element. The reshaping of the holding element sections then advantageously takes place in a force-controlled manner, so that they can be placed against the friction disk, in particular without play, and greater tolerances in the friction disk can be compensated for by the force coupling.

For example, the slide elements are spring-loaded coupled to the lifting element. In particular, a force coupling is implemented in a structurally simple manner. For example, the desired deformation behavior can be influenced by setting a spring stiffness when the spring is displaced.

In other preferred embodiments, the slide elements are pneumatically or hydraulically coupled to the lifting element.

In some embodiments it is provided that the slide elements are mounted so that they can be moved essentially radially with respect to the lifting element. This is advantageous, for example, with friction rings with little installation space, so that the slide elements can be moved radially further inward with the lifting element into the axle opening and there can act on the holding sections to be formed by a radially outward movement.

It is particularly advantageous if, during the reshaping of the holding element sections, the slide elements are moved essentially in the axial direction. This is particularly favorable since the brake cup and the friction ring are already brought together axially and the lifting element provides an axial movement and the method is simplified by these mere axial movements and the slide tool can be designed in a structurally simpler manner. Thus, in particular, the method can be carried out more cost-effectively and preferably less susceptible to failure.

In particular, the slide elements are moved essentially in the axial direction by means of the lifting element and its provided axial stroke.

It is particularly advantageous if, as a result of the essentially axial movement of the slide elements, they act on the holding element sections axially and at least partially deform them in the radial direction.

With regard to a movement of the sliding tool, no further details have so far been given.

In particular, it is provided that the slide tool, in particular with its lifting element and the slide elements, is moved onto the brake cup from an axial side opposite the mounting base. This is particularly favorable since the sliding tool, in particular with the sliding elements, is then moved directly towards the jacket wall and can form the holding elements in a simple manner.

In particular, it is provided that the sliding tool is moved onto the brake pot from an axial side which is opposite to the side in which the brake cup is arranged on the brake ring.

It is particularly advantageous if the sliding tool, in particular with its slide elements, is first moved through the axis opening of the other of the two friction disks and then moved to the brake pot. In this way, the sliding tool, in particular with its sliding elements, easily reaches an inner region that is radial to the jacket wall and can there form the holding element sections into holding elements, in particular radially outward.

With regard to the design of the slide elements, no detailed information has been given so far.

It is favorable if the slide elements comprise a deforming section for deforming a corresponding holding section to be deformed. In particular, the deformation section can be adapted accordingly in accordance with the desired deformation, so that an adapted and individual deformation of the holding element sections is preferably made possible.

In particular, it is provided that the deformation sections each have a deformation surface which is designed in accordance with the desired deformation.

It is particularly favorable if the deformation surfaces of the respective deformation sections are each designed to run obliquely to the axial and obliquely to the radial direction in relation to the brake system axis. In particular, a translation of an axial movement of the Allows slide element in a radial deformation of the holding element section.

In some particularly advantageous embodiments, it is provided that the deformed sections of at least some, in particular all, slide elements have a contact surface which are each designed to run at least approximately parallel to the radial direction. In particular, with the contact surfaces running at least approximately parallel to the radial direction, it is possible to shape the holding element sections into holding elements which at least in sections extend essentially parallel to the radial direction.

Such holding elements, which extend radially at least in sections, offer, for example, a stable axial hold and can, for example, also compensate for radial distortion of the friction disk, which can occur in particular due to heating of the same during operation of the brake system, to the extent that a sufficiently large contact surface is provided in the radial direction for axial holding becomes.

In particular, it is provided that a respective slide element first contacts the corresponding holding element section to be reshaped with its reshaping surface and, in particular when the holding element section is acted upon by the slide element, the corresponding holding element section to be reshaped is reshaped radially outward by the inclined reshaping surface.

In some advantageous embodiments it is provided that after a first reshaping of the corresponding holding element section through the reshaping surface, this holding element section comes into contact with the contact surface of the corresponding slide element. In particular, as a result of this application of this contact surface, the holding element section is at least partially deformed so as to extend at least approximately in the radial direction. Thus, a holding element which has the advantages explained above and which partially extends in the radial direction is preferably formed.

More detailed information on the arrangement of the deformed holding element sections has not yet been given.

It is particularly advantageous if the holding element sections are reshaped to form further holding elements which bear against a flat side of one of the two friction disks which is axially opposite the first flat side. In particular, holding elements are thus formed in different steps, which rest partly on the one flat side and partly on the other flat side of the friction disk and thus the establishment of a stable connection between the brake cup and the friction ring is made possible by the axial holding by the holding elements. It is particularly advantageous if the further holding elements rest against the flat sides at least axially without play.

For example, the first flat side is a flat side of the one of the two friction disks facing the other of the two friction disks and thus in particular a flat side of the one of the two friction disks that is on the inside with respect to the friction ring. In particular, the flat side axially opposite the first flat side is then an axially outwardly oriented flat side which in particular forms an outer side of the friction ring.

In other preferred embodiments it is provided that the first flat side of one of the two friction disks is an axially outwardly oriented flat side of this friction disk and in particular forms an outer side of the friction ring. In particular, the flat side axially opposite the first flat side is then a flat side facing the other of the two friction disks.

It is particularly advantageous if the one of the two friction disks, against which in particular the retaining elements formed from the retaining element sections rest and hold them, is a toothed friction disk, which is understood to mean that an edge section surrounding its axis opening has a toothing.

An exemplary embodiment shown in the figures as a whole with 100 designated brake system comprises a friction ring 112 and a brake pot 114 , which is coaxial with a braking system axis 118 are arranged, as for example in the 1 and 2 is shown.

The braking system 100 is intended for a motor vehicle, specifically for arrangement on a vehicle axle of the same. Here is the friction ring 112 in particular designed to cooperate braking with a brake caliper with brake linings during a braking process. The brake pot 114 is intended for assembly and attachment to a vehicle axle of the vehicle. Via a torque-transmitting connection between the brake cup 114 and the friction ring 112 During the braking process, the braking effect of the friction ring which interacts with the brake linings in a braking manner 112 on the brake pot 114 and further transmitted to the vehicle axle, so that a driving speed of the motor vehicle is reduced. In the assembled state, the vehicle axle is coaxial with the brake system axle 118 aligned.

The friction ring 112 includes two friction discs 132 and 134 . The friction disks 132 and 134 are coaxial to the brake system axis 118 arranged and spaced from each other in the axial direction. Between the two friction disks 132 , 134 struts extend 138 in the axial direction from one of the friction disks 134 , 132 up to the other friction disc 132 , 134 and so connect these friction disks 132 , 134 together. The struts preferably run obliquely to the radial direction outwards.

Preferably the struts define 138 cooling channels running obliquely radially outwards 136 . In particular, improved cooling is achieved as a result.

Preferably the two friction disks are 132 , 134 and the bracing 138 and in particular the entire friction ring 112 formed in one piece. For example, the friction ring 112 out a metallic material, in particular cast iron, formed, wherein in variants of the embodiment, the friction ring 112 is also formed from other materials, for example a ceramic material.

The friction ring 112 points on each of its axial outsides 142 , 144 one friction surface each 146 , 148 on. The friction surfaces 146 , 148 are designed in such a way that, during a braking process, the brake linings frictionally and thus brake on these friction surfaces 146 , 148 can act.

One of the friction disks forms each 132 , 134 one outside each 142 , 144 with the corresponding friction surface 146 , 148 off with a respective flat side 152 , 154 the respective friction disc 132 , 134 .

In addition, the friction disks 132 , 134 the outward-facing flat sides 152 , 154 axially opposite and based on the friction ring 112 internal flat sides 162 , 164 on which the struts 138 are molded.

In particular, the friction disk extends 132 essentially in one to the braking system axis 118 perpendicular geometric plane. The two flat sides 152 and 162 the friction disc 132 run on each side of this geometric plane and at least approximately parallel to it.

The other friction disc 134 likewise extends essentially in one direction to the brake system axis 118 perpendicular geometric plane and its two flat sides 154 and 164 run on each side of this geometric plane and at least approximately parallel to it.

In addition, the friction ring 112 an axle breakthrough 168 which is coaxial to the brake system axis 118 continuously from one outside 142 , 144 to the other outside 144 , 142 of the friction ring extends through it. In particular, the axle cutout is 168 to at least partially accommodate the brake cup 114 and intended for the implementation of the vehicle axle in the fully assembled state.

The two friction disks 132 , 134 each have an axle opening 172 , 174 on. The respective axle opening 172 , 174 extends coaxially to the brake system axis 118 in the axial direction through the corresponding friction disc 132 , 134 from one flat side 152 , 154 to the other flat side 162 , 164 . This forms the axle opening 172 , 174 the axle breakthrough 168 out. Because the bracing 138 in the radial direction not in the space between the axle openings 172 , 174 protrude is also this gap 146 between the axle openings 172 , 174 material-free. This is the axle cutout 168 axially continuous.

The two axle openings 172 , 174 are by respective edge sections 182 , 184 the corresponding friction disks 132 , 134 in to the braking system axis 118 limited radial direction and the edge portions 182 , 184 surround their corresponding axle opening 172 , 174 and are to the braking system axis 118 formed closed in the direction of rotation.

In particular, it is provided that the friction surfaces 146 , 148 on the respective outer flat side 152 , 154 radially in an outer area of the respective friction disk 132 , 134 and the braking system axis 118 are designed to be closed circumferentially in the direction of rotation. The friction surfaces 146 , 148 are therefore also the respective axle opening 172 , 174 formed circumferentially and spaced apart from this in the radial direction.

This defines the edge sections 182 , 184 their respective axle opening 172 , 174 and a diameter of these axle openings 172 , 174 , the diameter being measured in the radial direction to the brake system axis.

One of the edge sections 182 , 184 , here the edge section 182 , has a toothing 192 on, which is formed directed radially inward and in particular periodically in the direction of rotation around the brake system axis 118 is trained.

The gearing 192 points radially into the axle opening 172 protruding teeth 194 on which recesses 196 are arranged. The teeth 194 have radially protruding tooth tips, from which tooth flanks extend radially obliquely outward, which form the recesses 196 at the side and in the back of the recess 198 pass over. The recess backs 198 limit the recesses 196 in to the braking system axis 118 radial direction.

Thus, the edge portion 182 with the gearing 192 an alternating radial expansion along the direction of rotation R1 which has its smallest value Rimin for the tooth tips and Rimin for the recess back 198 assumes its greatest value Rlmax. The radial expansion R1 is based on the braking system axis 118 up to the corresponding radial limitation of the axis opening 192 measured. In particular, the diameter corresponds to the axle opening 172 essentially twice the radial extent R1 .

The teeth 194 and the recess backs 198 are from the corresponding edge section, here the edge section 192 , educated. This edge section is also the toothed edge section and the corresponding friction disk, here the friction disk 132 , is also called a toothed peripheral disc.

The teeth run in the axial direction to the brake system axis 194 and the recess backs 198 preferably from the one flat side to the other flat side of the toothed friction disk, in this case from the inner flat side 162 to the outer flat side 152 , continuously, so that they form edge surfaces running essentially perpendicular to the radial direction. In particular, there are cross-sectional shapes of the toothed friction disk with respect to all cross-sectional planes between their flat sides 152 , 162 as well as perpendicular to the braking system axis 118 run, essentially the same.

The other edge section, here the edge section 184 , is designed to be essentially constant with respect to its radial extent along the direction of rotation, so that the axis opening surrounded by it, here the axis opening 174 , a substantially constant radial extent R2 having. Here, too, is the edge section 184 in to the braking system axis 118 in the axial direction essentially continuously and identically.

In this embodiment it is advantageously provided that the non-toothed axle opening, that is to say here the axle opening 174 , has a greater radial extent than the axis opening with the toothed edge section. Here is the radial extent R2 the toothless axle opening 174 at least greater than the smallest radial extension Rimin of the toothed axle opening 172 and preferably is the radial extent R2 the toothless axle opening 174 greater than the maximum radial expansion Rlmax at the back of the recess 198 the toothed axle opening 172 .

Thus, the toothed edge portion 182 an exposed ring area 199 on, which in the axial direction is not from the toothless edge portion 184 is covered. In 3 and 4th this area is shown as an example between a toothed edge curve of the toothed edge section 182 and a dashed circle which is a radius R2 corresponding to the radial extent of the toothless axle opening 174 has and thus the dashed line also an axial projection of an edge curve of the toothless edge portion 184 on the toothed edge section 182 represents.

It is particularly favorable if the struts 138 radially inward only as far as the toothless edge section 184 protrude, so their radially inwardly lying ends at least a radial distance R2 from the braking system axis 118 to have.

The brake pot 114 , which is exemplified in 5 and 6th shown includes a submount 212 and a jacket wall 214 .

Preferably the mounting base 212 and the mantle wall 214 and in particular the entire brake pot 114 formed in one piece. The brake pot is more favorable 114 formed from a metallic material and preferably formed from a sheet metal.

The assembly base 212 , which in this embodiment as a flat substantially in one to the brake system axis 118 perpendicular geometric plane extending mounting disc is formed, is for mounting the brake cup 114 on the vehicle axle, for example a mounting flange of the same, is provided. This includes the mounting base 212 an opening formed coaxially to the brake system axis 221 for the implementation of the vehicle axle.

In particular, the mounting base includes 212 several fastening openings 222 , what a 5 merely schematically and not shown at all in the other figures for the sake of clarity, through which fastening means, in particular screws, can be passed for fastening to the vehicle axle.

In particular, the mounting base 212 one to the braking system axis 118 radial expansion, which is approximately a radial expansion of the axle opening 168 of the friction ring 112 corresponds, in particular, to ± 5% of the radial expansion of the axle openings 172 , 174 corresponds to.

At the assembly base 212 , in particular on a radial outer edge portion 224 the same is the mantle wall 214 with a base area 232 same on the mounting base 212 arranged and the jacket wall 214 extends from its base area 232 in to the braking system axis 118 axial direction from the submount 212 away to a wall end area 234 the mantle wall 214 .

The mantle wall 214 has a toothing 242 on which to gearing 192 of the toothed edge section 182 is designed accordingly. The teeth 242 has teeth 244 and recesses in between 246 on, which in terms of their radial extent and their extent in the direction of rotation corresponding to the Recesses 196 and teeth 194 the gearing 192 of the toothed edge section 182 are designed so that in an assembled state the teeth 244 the mantle wall 214 into the recess 196 the gearing 192 and teeth 194 the gearing 192 into the recesses 246 the teeth 242 intervention. This means that the brake cup is in the assembled state 114 and the friction ring 112 by means of the interlocking teeth 192 and teeth 242 Connected in a torque-transmitting manner, the torque in particular via tooth flanks of the respective teeth 194 and 244 is transferred to the other teeth.

Thereby the teeth 242 by wall segments arranged alternately in the direction of rotation and radially offset from one another 252 , 254 educated. Wall segments arranged radially somewhat inwards 252 form the teeth 244 and radially recessed wall segments 254 form the radial limit for the recesses 246 out. Intermediate segments 256 run essentially in the radial direction or at an angle to this and connect the wall segments protruding radially inward 252 with the wall segments set back radially to these adjacent ones 254 . Thus form the intermediate segments 256 also tooth flanks for the teeth 244 out.

Here are the wall segments 252 , 254 and the intermediate segments 256 formed essentially continuously both in the axial direction and in the circumferential direction, so that the jacket wall 214 in the axial direction from the base region 232 up to the wall end area 234 and is designed as a substantially continuous wall in the circumferential direction.

The brake pot 114 points on the jacket wall 214 a variety of retaining elements 312 , 314 on, wherein a first subset of holding elements 312 at the wall end area 234 and a second subset of retaining elements 314 in a central area 318 the mantle wall 214 is arranged. The middle area 318 lies axially between the base region 232 and the wall end area 234 and runs like this in the direction of rotation closed around the brake system axis 118 around. An axial distance of the central area 318 from the wall end area 234 corresponds essentially to an axial thickness of the toothed friction disk 132 and also the holding elements 312 of the first subset are spaced from the holding elements at a distance corresponding to this axial thickness 314 the second subset arranged at a distance.

The holding elements 312 and 314 are in the area of the recesses 246 arranged in each recess 246 at most one retaining element 312 , 314 . In this embodiment it is provided that in the area of each recess 246 exactly one retaining element 312 , 314 is arranged. In variants of the exemplary embodiment, however, there are also recesses 246 provided, in the area of which there is no holding element 312 , 314 is arranged.

The holding elements 312 the first subset and the holding elements 314 of the second subset are arranged alternately, that is, alternately, in the direction of rotation. In the case of adjacent recesses in the direction of rotation 246 are therefore each holding elements 312 , 314 the respective other subset arranged. For example, a recess follows 246 with a holding element 312 the first subset a recess in the direction of rotation 246 with a holding element 314 the second subset and vice versa. In the variant with a few cutouts 246 without a retaining element, a recess follows in particular 246 with a holding element 312 the first subset has a recess without a holding element and then a recess 246 with a holding element 314 the second subset and then again a recess 246 without holding element and immediately.

The holding elements 312 , 314 lie on the opposite flat sides 152 , 162 the toothed friction disc 132 axially and essentially without play, so that the friction ring 112 and the brake pot 114 Free of play at least in the axial direction due to the large number of holding elements 312 , 314 are held together. The holding elements 312 the first subset are on the inside flat side 162 , especially on their exposed ring area 199 , on and the retaining elements 314 the second subset are on the outside 142 training flat side 152 on.

This is exemplified in the 7th to 11 shown.

The holding elements grip 312 , 314 especially in the area of the teeth 194 of the toothed edge section 182 on.

The holding elements 312 , 314 a first group are as retaining tongues 322 comprehensive holding elements 312 , 314 formed and the holding elements 312 , 314 a second group are designed as bridge-like holding elements. In the case of the 1 to 11 The variant of the embodiment shown as an example are the holding elements 312 the first subset according to the first group as holding tongues 322 comprehensive holding elements and the holding elements 314 of the second subset are designed as bridge-like holding elements according to the second group.

The holding tongues 322 include a foot area 324 with which they in one Transition area 326 are arranged on the jacket wall in the wall end area 234 a recess 246 . The transition area 326 and also the foot area 324 run essentially in the direction of rotation and the retaining tongue 322 extends transversely to this, in particular obliquely to the radial and axial direction, from the transition area 326 away to the tip of a tongue 332 in a free end area 334 the holding tongue 322 .

For example, the retaining tongue extends 322 in the assembled state essentially up to the tip of the tongue 332 substantially obliquely to the radial and axial direction radially outwards and lies with one of the friction washers 132 facing system side on this at least partially.

In preferred variants of the exemplary embodiment, at least the free end region extends 334 the holding tongue 322 at least approximately parallel to the radial direction outwards and its contact side also runs essentially parallel to the radial direction, as for example in FIG 11 is shown.

Preferably, a length corresponds to the extension of the holding tongues 322 from the foot area 324 to the tip of the tongue 332 at least approximately the difference in the radial dimensions of the axle openings 172 , 174 so that the retaining tongue 322 along much of the exposed ring area 199 in the area of a tooth 194 is applied to this.

The bridge-like holding elements 314 of the second group comprise a bridge part 342 , which is between two connecting parts 344 , 346 is designed to extend substantially in the direction of rotation. The bridge part 342 essentially bridges a recess 246 , in the area of which the corresponding bridge-like holding element 314 is arranged. With the connecting parts 344 , 346 is the bridge part 342 on the jacket wall 214 arranged. In particular, the connecting parts extend 344 , 346 from each end of the bridge part 342 up to a tooth flank and the recess 246 laterally limiting intermediate segment 256 . The bridge part 342 is further radially inward than the recessed wall segment 254 arranged and in particular even further radially inward than the protruding wall segments 252 arranged. Thus, the connecting parts run 344 , 346 in particular radially inward from the intermediate segment 256 or a protruding wall segment 252 to the bridge part 242 .

It is particularly favorable if the bridge-like holding element 314 from the mantle wall 214 is punched out, in particular the bridge part 342 from a recessed wall segment 254 and the connecting parts 344 , 346 from the side to the recessed wall segment 254 arranged intermediate segments 256 are punched out. Thus, in particular, the jacket wall which runs essentially continuously is 214 only in the area of these punched-out retaining elements 314 partially interrupted.

The bridge parts are in the assembled state 342 especially without play on the one outside 142 forming flat side 152 the toothed friction disc 132 on and at their toothed edge section 182 , especially in the area of a tooth 194 .

Thus, the structure and function of the friction ring 112 and the brake pot 114 comprehensive braking system 100 briefly summarized in particular as follows:

The friction ring 112 points on the axial outsides 142 , 144 each friction surface 146 , 148 on, which can cooperate with brake pads of a brake caliper in a braking manner. This braking effect is provided by the friction ring 112 via the torque-transmitting connection between its teeth 192 and the teeth 242 of the brake cup 114 transferred to this. At the assembly base 212 is the brake pot 114 mountable on a vehicle axle and thus transmits the braking effect to the vehicle axle for braking a motor vehicle having this vehicle axle.

For a safe and less failure-prone connection of the brake cup 114 with the friction ring 112 hold the retaining elements 312 , 314 the friction ring 112 on the toothed friction disc 132 play-free at least in the axial direction. The holding elements grip 312 the first part on the inside flat side 162 , especially in the exposed ring area 199 , and the retaining elements 314 the second subset on the flat side facing outwards 152 the toothed friction disc 132 on. For holding the friction ring free of play 112 on the friction disc 132 are the holding elements 312 the first subset and the holding elements 314 the second subset in the axial direction essentially in one of the axial thickness of the friction disk 132 corresponding distance on the shell wall 214 of the brake cup 114 arranged.

Holding elements of a first group are essentially as holding tongues 322 educated. These holding tongues 322 are with a foot area 324 arranged on the shell wall and extend from the shell wall 214 away to a free end area 334 . These holding tongues 322 can be easily bent during assembly and attached to the Friction disc 132 Press down to hold it backlash-free. In particular, the retaining tongues 322 bent in such a way that through this the friction disc 132 between the retaining tongues 322 and the holding elements 312 , 314 , which on the other axially opposite flat side 162 , 164 are arranged, is pinched.

Holding elements of a second group are designed as bridge-like holding elements and have a corresponding recess 346 bridging part of the bridge 342 Mistake. In the direction of rotation, the bridge part settles on the opposite ends 342 this in connection parts 344 , 346 away, which on the mantle wall 214 , in particular intermediate segments forming tooth flanks 256 or to the teeth 244 forming wall segments projecting radially inward 252 the mantle wall 214 , are arranged. In particular, these bridge-like retaining elements of the second group form stable axial stops which are used when the brake system is installed 100 for positioning the friction ring 112 relative to the brake pot 114 by placing the bridge-like retaining elements on the corresponding flat side 152 , 162 the friction disc 132 can be used and by a subsequent reshaping of the opposite flat side 152 , 162 attacking retaining elements 312 to bring about backlash-free holding.

A braking system 100 , which has a friction ring 112 and a brake pot 114 comprises and is designed in particular as explained above, is produced, for example, as follows.

First is a friction ring 112 with two friction discs 132 , 134 , which are arranged axially spaced from one another and each have an axis opening 172 , 174 have, which together have one from an outside 142 , 144 to the other outside 142 , 144 the friction ring 112 axially penetrating axle opening 168 train for implementation of a vehicle axle, provided. It has an axle opening, for example the axle opening 172 , a toothing 192 on that of an edge portion surrounding the axle opening 182 is trained.

There is also a brake pot 114 with a mounting base intended for mounting on the vehicle axle 212 and one from the mounting base 212 axially extending jacket wall 214 provided. The jacket wall 214 a toothing 242 on which corresponds to the toothing 192 is trained.

In addition, the provided brake pot 114 on the mantle wall 214 molded retaining element sections 412 , 414 on which to a first subset of holding elements 312 and a second subset of holding elements 314 are to be reshaped, as exemplified in the 12th is shown.

Retaining element sections extend in this case 414 , from which bridge-like holding elements according to a second group of holding elements 314 are to be formed, essentially in the circumferential direction in a radially set back wall segment 254 and with sections which become connecting parts 344 , 346 In particular, up to the adjacent intermediate segments should be reshaped 256 into it. Axially next to the retaining element sections 414 Material-free sections run for the bridge-like holding elements 422 , 424 . These material-free sections 422 , 424 likewise extend essentially in the circumferential direction in the recessed wall segment 254 and in particular down to the adjacent intermediate segments 256 and optionally up to the wall segments projecting radially inwardly adjacent thereto 252 into it. For example, the material-free sections 422 , 424 punched out areas.

These retaining element sections 414 are reshaped radially outwards so that their in the area of the wall segment 254 running area the bridge part 342 and those in the area of the intermediate segments 256 running areas the connecting parts 344 and 346 form. In particular, holding elements forming axial stops are formed in this way.

For example, the holding element sections run 414 for the bridge-like holding elements in a central area 318 the mantle wall 214 and so the bridge-like holding elements are formed in this central area.

This one with in the middle area 318 with holding elements 314 provided brake pot 114 becomes with the wall end area 234 ahead into the axle opening 172 with the toothed edge section 182 inserted until the molded retaining elements 314 on the outside 142 issue. So then is the shell wall 214 from their wall end area 234 up to about the middle area 318 in the axle opening 168 namely on the toothed edge section 182 arranged adjacent.

Since preferably the wall end area 234 essentially corresponding to the axial thickness of the friction disc 132 from the central area 318 is spaced closes the shell wall 214 essentially axially flush with the inner flat side 162 the friction disc 132 from.

The retaining element sections 412 for the holding elements of the first group extend in this embodiment in the still unformed Condition of your foot area 324 with which they are connected to a transition area 326 a corresponding recess 246 in the wall end area 234 are arranged axially up to the tip of the tongue 332 in a free end area 334 , as exemplified in 12th is shown.

For reshaping these holding element sections 412 becomes a whole with 440 designated slide tool is used, which in 13th is shown schematically.

The slide tool 440 includes a lifting element 442 , to provide an axial stroke, as well as slide elements 444 which is attached to the lifting element 442 , in particular each individually, are coupled. The number of slide elements corresponds to this 444 preferably exactly the number of holding element sections to be reshaped 412 so that in each case exactly one retaining element section 412 of exactly one slide element 444 is reshaped.

Preferably the slide elements are 444 each individually to the lifting element 442 force-coupled. For example, it is provided that the slide elements 444 spring-loaded on the lifting element 442 are arranged.

The slide elements 444 include on an axial front side 452 a deformation section 454 . This has at least one forming surface 456 which runs obliquely radially outwards, so that areas of the forming surface that are located radially further inward 456 protrude axially further than radially outer areas of the forming surface 456 .

The slide elements 444 are corresponding to the retaining element sections to be reshaped 412 arranged relative to each other.

The next step is the slide tool 440 in the axle opening 168 led in first through the toothless axle opening 174 which have a larger diameter than the toothed axle opening 172 has so that each of the slide elements 444 essentially in the axial direction on the respective holding element section to be reshaped by it 412 can be moved closed.

The lifting element 442 provides an axial stroke and the slide elements 444 push through their coupling to the lifting element 442 in the axial direction on the free end area 334 with their inclined forming surface 456 .

By means of the axial loading by the slide element 444 is due to the inclined forming surface 456 the retaining element section 412 pushed away radially outwards and as a shaped retaining tongue 322 to rest on the inner flat side 162 , especially in the exposed ring area 199 same, brought.

Through the force coupling of the slide elements 444 the holding element sections are folded over 412 force-controlled, so that each of the retaining element sections 412 in the axial direction backlash-free on the inner flat side 162 the friction disc 132 is applied and surface inaccuracies on this flat side at each holding section 412 be balanced individually. This means that there are greater tolerances for the nature of the flat side 162 the friction disc 132 tolerable.

It is particularly favorable if the slide elements 444 at their forming section 454 still contact surfaces 458 have, which are located radially outside on the forming surface 456 connect and run essentially in the radial direction to the brake system axis. This becomes the corresponding holding element section 412 first from the forming surface 456 pressed radially outwards and then by means of the contact surface 458 bent over by at least approximately 90 ° relative to the axial direction, so that the holding element 312 training tongue 322 at least in their free end area 334 extends at least approximately in the radial direction.

With regard to a variant of the exemplary embodiment, which is exemplified in 14th is shown, the following essentially only deals with the different designs and, unless otherwise explained, features and elements in this variant are designed as explained above. In the following, features and elements which are essentially embodied in the same way or which at least fundamentally fulfill the same function are provided with the same reference symbols. In particular, if reference is to be made to the special design in this variant, a suffix “a” characterizing this variant is appended to the corresponding reference symbol.

In this variant, the shaft opening is not toothed 174a an essentially equal radial extent R2 on, like the toothed axle opening 172 in the area of the teeth 194 .

The further configuration of the braking system 100a with the brake pot 114 and the friction ring 112 , which by the plurality of holding elements 312 , 314 are kept free of play at least in the axial direction, is otherwise at least fundamentally the same as in the variant described above, so that reference is made in full to the above explanations with regard to the further elements and features.

In the manufacture of this braking system 100a with essentially the same size axle openings 172a and 174a can the slide elements 444 no longer axially on the holding element sections to be reshaped 412 are fed. Therefore, in this variant, the slide elements are in the slide tool during manufacture 440a first arranged further radially inwardly offset.

In addition, the slide elements are 444a radially movable on the lifting element 440a , in particular each individually and force-controlled, arranged stored.

It is used in the process of manufacturing the braking system 100a initially proceeded as explained above. Instead of that the slide elements 444a but then by means of the lifting element 442 axially onto the holding element sections to be reshaped 412 are fed, the slide elements are in this variant 444a by means of the lifting element 442a axially in the axle opening 168 initially through the toothless axle opening 174 inserted and then in the area of the toothed axle opening 172 brought so that the slide elements 444a in the axial direction approximately at the level of the holding element sections to be reshaped 412 are arranged.

Then these slide elements 444a by means of their radial mounting relative to the lifting element 442 relative to this, radially outwards onto the holding element sections to be reshaped 412 moved closed and then press them radially outward, so that again at least in the axial direction play-free application of the by the holding element sections 412 trained retaining tongues 322 he follows.

Again, the retaining tabs 322 depending on the variant, obliquely to the radial direction or at least in its free end area 334 reshaped to extend substantially in the radial direction.

At one in the 15th to 19th Another variant of the braking system shown 100b those elements and features which are at least essentially the same or which at least basically fulfill the same function as in the variants explained above are provided with the same reference symbols. With regard to the description of the same, reference is made to the full content of the preceding statements, unless otherwise stated below. In particular, a suffix “b” characterizing this variant is appended to the reference symbols, provided that particular reference is to be made to an embodiment in this variant.

The braking system also includes this variant 100b a friction ring 112 and a brake pot 114 .

As explained above, the friction ring comprises 112 two friction discs 132 and 134 with respective axle openings 172 , 174 , which has the axle opening 168 form. One of the axle openings, here the axle opening 172 , has an edge portion 182 with a toothing 192 on. The other axle opening, here the axle opening 174 , has essentially the same radial extent as the toothed axle opening in some variants 172 on and with other variants a larger radial expansion.

The brake pot 114 in this embodiment has on its jacket wall 214 again two subsets of holding elements 312b and 314b on the one hand in the wall end area 234 and on the other hand in the middle area 318 the mantle wall 214 are arranged.

In this variant, however, are the holding elements 312b that in the wall end area 234 are arranged as bridge-like holding elements 312b educated. These in turn comprise a bridge part extending essentially in the circumferential direction 342 , which at its ends in connecting parts 344 , 346 passes over and by means of this on the shell wall 214 is arranged. Again, these are bridge-like retaining elements 312b preferably from the shell wall 214b , especially from the recessed wall segments 254 and the intermediate segments 256 and optionally at least partially also from the radially protruding wall segments 252 punched out.

The ones in the middle area 318 arranged holding elements 314b are essentially as retaining tongues in this variant 322 educated. These are in turn with a foot area 324 at a transition area 326 on the jacket wall 214 , especially a recessed wall segment 254 , arranged and extend to the tip of the tongue 332 in a free end area 334 , which in this embodiment is now on an outer flat side 152 the friction disc 132 is applied and in particular essentially without axial play.

In the manufacture of this braking system 100b becomes the brake cup again 114 with its mantle wall 214 in the toothed axle opening 172 in such a way that the area between the central area 318 and the wall end area 234 to the toothed edge section 182 is applied.

In this variant, it is preferred that the non-toothed axle opening 174 is designed to be radially larger than the toothed axle opening 172 so that the bridge-like retaining elements 312b before inserting the brake cup 114 in the friction ring 112 can be shaped. Due to the larger toothless axle opening 174 then also fit the already formed holding elements 312b .

Thus, it is then provided that the brake cup in the axial direction with its mounting base 212 first through the non-toothed axle opening 174 and then through the toothed axle opening 172 through into the friction ring 112 is used until the bridge-like retaining elements 312b in abutment with the inner flat side 162 come.

In the case of this variant, there are also shaft openings of essentially the same size in the radial direction 172b and 174b possible. Then the brake pot 114 first with its mantle wall 214 in the toothed axle opening 172 arranged and then the holding elements 312b , in particular by radially mounted slide elements, formed by radial deformation.

The ones from holding tongues 322 trained holding elements 314b are made from corresponding retaining element sections 414b educated. The retaining element sections 414b are with their foot area in the undeformed state at a transition area 326 the mantle wall 214 arranged and otherwise from a material-free section 422b surround and thus extend from your foot area 324 in the axial direction up to the tip of the tongue 332 in a free end area 334 .

These retaining element sections 414b are carried out radially on the lifting element 442b mounted slide elements 444b Folded radially outwards and for at least play-free application in the axial direction to the outer flat side 152 the friction disc 132 brought to the cause.

Again, in this variant it is provided that the holding tongues 322b essentially to the tip of your tongue 332 extend radially outwards obliquely to the radial direction and / or that the retaining tongues 322 be folded over in such a way that at least their free end region 334 in the deformed state extends substantially outward in the radial direction.

All other features and elements are the same as in the variants discussed above, so that with regard to these, reference is made in full to the explanations given above.

In yet another variant of the exemplary embodiment, it is provided that the holding elements 312 , 314 of the first and second subset are partially designed according to both the first group and the second group. Otherwise, all elements and features are designed at least essentially the same as in the variants discussed above, so that reference is made to these discussions in their entirety.
