Description

[0001] The invention relates to a braking system, in particular a braking system for a motor vehicle.

[0002] The object underlying the invention is to improve a braking system.

[0004] In particular, an advantage of the solution according to the invention is that, for example, material can be saved since the brake pot does not protrude beyond the edge section with which it is engaged and thus no material is required for a protruding section.

[0005] In particular, one advantage of the solution according to the invention is that more free space is available in the area of the axle opening, since no section of the brake chamber protrudes beyond the edge section with which a section of the brake chamber engages. For example, the free space can be used for brake material, in particular a brake pad. For example, the free space can be used to better direct cooling air flows in the brake ring, in particular without being impaired by a protruding section of the brake chamber.

[0030] In advantageous embodiments, it is provided that the brake pot is flush with the edge section (with which the brake pot is engaged) of the brake ring in the axial direction of the brake system axis.

[0031] In particular, one advantage of this is that at least substantially the entire edge section can be used for arranging the brake pot, in particular at least a part of the protruding section of the brake pot, in particular for the engaging arrangement and / or adjacent arrangement, and on the other hand an excess section of the brake pot which protrudes beyond the edge section is avoided.

[0032] In particular, at least one of the following is provided: - that the brake pot, in particular with its casing wall and / or with its toothing, is arranged flush with the second axial end side of the edge section; and / or - that the brake pot, in particular with its casing wall and / or with its toothing, is arranged at the second axial end of the edge side of the edge section so as to be flush with the edge side; and / or - that the brake pot, in particular with its casing wall and / or with its toothing, is arranged flush with that transverse surface of the edge section which is located on the second axial end side of the edge section.

[0034] For example, an advantage of at least one of the above features is that the toothing and teeth in the axial direction can be used to the greatest possible extent for intermeshing.

[0035] Advantageously, the brake pot and the brake ring are fastened to each other in such a way that an axial relative displacement between the brake pot and the brake ring is prevented as much as possible.

[0036] In advantageous embodiments, retaining elements are provided that hold the brake pot and the brake ring together. In particular, the retaining elements provide axial locking against axial displacement of the brake pot relative to the brake ring.

[0037] In favorable embodiments, the brake pot comprises holding elements for holding on to the brake ring and preferably the brake pot forms holding elements.

[0038] It is particularly advantageous if the brake chamber comprises retaining elements of a first group and retaining elements of a second group, wherein the retaining elements of the first group, on the one hand, and the retaining elements of the second group, on the other hand, are arranged axially offset from one another in the axial direction of the brake system axis. Advantageously, the retaining elements of the first group, on the one hand, and the retaining elements of the second group, on the other hand, hold at least a portion of the brake ring axially between them.

[0039] Advantageously, the brake pot and the brake ring are arranged in such a way that they are held together by the holding elements, in particular the holding elements of the first group and the second group, that an axial relative displacement between the brake pot and the brake ring is prevented as much as possible.

[0040] In particular, the holding elements of the second group are arranged further away in the axial direction of the brake system axis from the axial outer side of the brake ring, from which the brake pot projects axially into the axle opening, than the holding elements of the first group.

[0041] In some advantageous embodiments, it is provided that at least some holding elements of the brake pot, in particular the holding elements of the second group, are arranged within an axial height range of the edge portion (with which the brake pot is engaged).

[0042] In particular, at least some holding elements, in particular at least some and preferably at least most and, for example, all of the holding elements of the second group, are formed on the free axial end of the jacket wall of the brake pot.

[0043] Advantageously, the retaining elements can thus hold the brake chamber and the brake ring together. Advantageously, the retaining elements do not protrude beyond the edge section in the axial direction of the brake system axis (at least on a side facing away from the axial outer side from which the brake chamber protrudes axially into the axle opening).

[0044] In particular, the axial height range of the edge portion is defined as the axial range along the brake system axis which is axially located between the two axial end sides of the edge portion and / or which is axially located between the two axial ends of the edge side of the edge portion.

[0045] It is particularly advantageous if no holding elements for the holding connection between the brake pot and the brake ring are arranged in the axial region which extends from the second axial end side of the edge section axially to the brake system axis from the edge section.

[0046] In particular, holding surfaces are provided, with a respective holding element resting on a holding surface.

[0047] In some advantageous embodiments, it is provided that at least some holding elements, in particular the holding elements of the first group, rest on a respective holding surface (of a first group) of the brake ring.

[0048] For example, these holding surfaces of the first group are formed on the first axial end side of the edge section and / or on the first transverse surface of the edge section and / or on the axial outer side of the brake ring, from which the brake pot projects axially into the axle opening.

[0049] In advantageous embodiments, it is provided that the edge portion (which engages with a portion of the brake pot) forms a plurality of holding surfaces within its axial height range, in particular forms holding surfaces (of a second group) for the holding elements of the second group.

[0050] Advantageously, retaining elements of the brake pot, in particular the retaining elements of the second group, can thus rest against a respective retaining surface of the edge section, preferably without protruding axially beyond the edge section.

[0051] In some preferred embodiments, it is provided that at least some holding surfaces formed on the edge portion, in particular holding surfaces for the holding elements of the second group, are arranged axially set back in the axial direction of the brake system axis.

[0052] In particular, the axially recessed retaining surfaces are arranged axially recessed in the axial direction into the axial height region of the edge section.

[0053] Preferably, at least some of the axially set-back retaining surfaces are arranged axially set back in the axial direction of the brake system axis with respect to the second axial end side of the edge section, in particular at least with respect to the second transverse surface on the second axial end side, and / or with respect to the second axial end of the edge side of the edge section, in particular are arranged axially set back in the height region of the edge section.

[0054] Advantageously, retaining elements can thus rest against the axially recessed retaining surfaces without projecting axially beyond the edge portion, in particular without projecting axially beyond the second axial end side and / or beyond the second axial end from the axial height region of the edge portion.

[0055] In particular, at least some of the holding surfaces formed within the axial height region and / or the axially set-back holding surfaces, in particular the holding surfaces for the holding elements of the second group, are formed facing away from the axial outer side of the brake ring, from which the brake pot projects axially into the axle opening.

[0056] In favorable embodiments, at least some teeth of the toothing of the brake ring each form at least one holding surface, in particular at least one holding surface for a holding element, for example of the brake pot.

[0057] Advantageously, teeth can be formed from recesses in the teeth of the brake pot, which can then rest on the holding surface of a corresponding tooth of the toothing.

[0058] In particular, at least some teeth of the toothing of the brake ring each form a holding surface (of a first group) for a respective holding element of the first group.

[0059] Advantageously, at least some teeth of the toothing of the brake ring each form a holding surface (in particular of a second group) for a respective holding element of the second group.

[0060] In some advantageous embodiments, it is provided that at least some teeth of the toothing of the brake ring are at least partially shortened in the axial direction of the brake system axis, in particular are shortened with respect to an axial extent of the toothing.

[0061] Advantageously, by virtue of the fact that a tooth is at least partially shortened in the axial direction, a free space is created in the region of this tooth within the height region of the edge section (with the toothing), in which free space a holding element of the brake pot can advantageously be arranged for a holding arrangement.

[0062] In particular, it is provided that at least some of the at least partially shortened teeth of the toothing of the brake ring are shortened in such a way that they do not extend axially in the axial direction of the brake system axis at least partially to the second axial end side of the edge section (with which the brake pot is at least partially engaged), in particular at least not to the second transverse surface on the second axial end side, and / or at least partially not to the second axial end of the edge side of the edge section.

[0063] Advantageously, on the axial side on which the brake pot does not protrude beyond the edge section, a free space is formed, in particular for a holding element, with a correspondingly shortened tooth.

[0064] In particular, at least some of the retaining surfaces, for example, at least some of the retaining surfaces of the first group, are configured to extend at least substantially perpendicular to the axial direction of the brake system axis. For example, such retaining surfaces are suitable for axially positioning the brake ring and the brake chamber relative to one another. In particular, such retaining surfaces are suitable for a retaining element configured as an axial stop.

[0065] In particular, at least some retaining surfaces, for example, at least some retaining surfaces of the second group, are designed to extend obliquely to the axial direction of the brake system axis. Such retaining surfaces are particularly suitable for securing the brake pot and the brake ring to one another with as little play as possible.

[0066] Advantageously, a retaining element is applied to such an inclined retaining surface in order to ensure proper axial relative positioning of the brake ring and the brake pot to each other.

[0067] For particularly favorable designs of an obliquely extending holding surface and, for example, advantages thereof and preferred designs of the holding surface and holding elements adjacent thereto, reference is also made in full to the document DE 10 2021 118 571 A1 and the disclosure of which is incorporated herein in full.

[0068] In some particularly advantageous embodiments, at least one of the following is provided: - that the brake ring and the brake chamber are at least partially connected to each other by a clamped connection; and / or - that the brake ring and the brake chamber are at least partially connected to each other by a self-locking connection; and / or - that the brake ring and the brake chamber are at least partially connected to each other by a connection which is under prestress.

[0069] For example, one advantage of this is that the brake ring and the brake pot are stably connected to each other even under changing, particularly axial, loads and, advantageously, no play occurs between the brake ring and the brake pot even under changing loads.

[0070] For advantageous embodiments of a self-tensioned connection and / or a self-locking connection and / or a connection that is under prestress, reference is also made in full to the document DE 10 2021 118 571 A1 and the disclosure of which is incorporated herein in full.

[0071] In particular, it is provided that the brake ring comprises at least one friction disc, i.e. in particular comprises exactly one friction disc or comprises several friction discs.

[0072] In particular, at least one friction surface of the brake ring is formed in at least one friction disc. In particular, the friction surface is designed to be acted upon by a brake shoe. In particular, the friction surface is designed for braking interaction with a brake shoe.

[0073] For example, a friction surface on the friction disc is formed (in particular directly) by the material of the friction disc.

[0074] For example, a friction surface (in particular indirectly) is formed on the friction disc by arranging a braking material in the region of the friction surface on the friction disc.

[0075] It is particularly advantageous if the edge section with which at least one section of the brake pot is in engagement is an edge section of a friction disc of the at least one friction disc (i.e. exactly one friction disc or one of the several friction discs).

[0076] In some particularly advantageous embodiments, it is provided that a plurality of cooling channels are formed in the brake ring. Advantageously, at least some of the plurality of cooling channels open radially inward into the axle opening relative to the brake system axis.

[0077] It is particularly advantageous if the brake pot does not protrude into the openings of at least some, preferably at least most and, for example, all, of the plurality of cooling channels in the axial direction of the brake system axis.

[0078] It is particularly advantageous if the openings of at least some, preferably at least most and, for example, all, of the plurality of cooling channels are free from a section of the brake pot.

[0079] Advantageously, the flow of cooling air from the axle opening into the cooling channels and / or from the cooling channels into the axle opening is not impaired by a section of the brake pot.

[0080] In some advantageous embodiments, it is provided that a brake pad is arranged on at least one axial outer side of the brake ring.

[0081] In advantageous embodiments, it is provided that the brake pot, in particular with its casing wall, does not protrude into the axial region of at least one brake pad in the axial direction of the brake system axis, wherein this brake pad is arranged in particular on an opposite axial outer side of the brake ring and the opposite outer side is located in the axial direction of the brake system axis opposite the axial outer side of the brake ring, from which the brake pot protrudes axially into the axle opening.

[0082] In particular, the axial region of the brake pad is the axial region along the brake system axis in which the brake pad is arranged.

[0083] For example, one advantage of the brake pot not protruding into the axial area of the brake pad is that more free space is provided for the brake pad.

[0084] For example, one advantage of the brake pot not extending into the axial area of the brake pad is that even if the brake pad wears out, the brake pot does not extend axially beyond the brake pad, thus avoiding any complications that may arise.

[0085] Above and below, the terms “axial” and “radial” generally refer to the axial and radial directions of the brake system axis.

[0093] An embodiment of a braking system designated as a whole by 100, which is shown by way of example in the Fig. 1 to 9, comprises a brake ring 112 and a brake pot 114, which are arranged coaxially to a (geometric) brake system axis 118, as shown by way of example in the Fig. 1 to 3.

[0094] In particular, the braking system 100 is intended for a motor vehicle, specifically for arrangement on an axle of the vehicle. In particular, in the assembled state, the braking system axis 118 is aligned coaxially with the axle of the vehicle.

[0095] The brake chamber 114 is intended for attachment to an axle of the motor vehicle. The brake ring 112 is particularly designed to interact with the brake pads of a brake caliper during a braking operation. Via a torque-transmitting connection between the brake chamber 114 and the brake ring 112, the braking effect of the brake ring 112, which interacts with the brake pads, is transmitted to the brake chamber 114 during the braking operation, so that the braking effect is also transmitted to the axle of the vehicle.

[0096] The brake ring 112 is formed, for example, from two friction discs 122, 124, which are connected to one another in particular by struts 126 running between the two friction discs 122, 124.

[0097] Preferably, the friction discs 122, 124 and the struts 126 are formed in one piece.

[0098] For example, the friction discs 122, 124 and the struts 126 are made of a metallic material, such as cast iron. In variants, the friction discs 122, 124 and, for example, the struts 126 are, in particular, at least partially made of a ceramic material.

[0099] One of the friction discs, here the friction disc 122, has two flat sides 132 and 134 and the other of the two friction discs, here the friction disc 124, also has two flat sides 136 and 138, as shown by way of example in the Fig. 4 shown sectional view.

[0100] The flat sides 132, 134, 136, 138 of the friction discs 122, 124 run at least substantially perpendicular to the brake system axis 118.

[0101] The friction discs 122, 124 each face one another with a flat side, here with the flat side 134 of the friction disc 122 and with the flat side 136 of the friction disc 124, and in particular the struts 126 are arranged on these flat sides 134, 136 facing the other friction disc 122, 124 and thus connect the friction discs 122, 124.

[0102] Preferably, the struts 126 extend obliquely outwards to the radial direction of the brake system axis 118.

[0103] Preferably, cooling channels 142 are formed in the brake ring 112 between the friction discs 122, 124 by the struts 126.

[0104] One flat side of each friction disc, here the flat side 132 of the friction disc 122 and the flat side 138 of the friction disc 124, are formed on a respective axial outer side 152, 154 of the brake ring 112.

[0105] In particular, the two axial outer sides 152, 154 are formed opposite to each other in the axial direction 155 of the brake system axis 118 in the brake ring 112.

[0106] In particular, the flat side 132, 138 of a friction disc 122, 124 formed on an axial outer side 152, 154 is located opposite the flat side 134, 136 of this friction disc 122, 124, which faces the other friction disc 124, 122, in the direction 155 axial to the brake system axis 118.

[0107] Advantageously, the brake ring 112 has a respective friction surface 156, 158 on its axial outer sides 152, 154, which are formed in particular in a region of the axial outer sides 152, 154 that is radially outer to the brake system axis 118.

[0108] The friction surfaces 156, 158 are designed such that during a braking operation, brake pads of the brake system 100 can act on these friction surfaces 146, 148 in a rubbing and thus braking manner.

[0109] In addition, the brake ring 112 has an axle opening 162.

[0110] The axle opening 162 is delimited by a radial inner side 164 of the brake ring 112 in a direction 163 radial to the brake system axis 118. The radial inner side 164 extends in a circumferential direction 165 in a closed manner around the brake system axis 118 and the axle opening 162.

[0111] The axle opening extends coaxially to the brake system axis 118 continuously from one axial outer side 152 to the other axial outer side 154 of the brake ring 112 through the latter.

[0112] In particular, the axle opening 162 is provided for at least partially receiving the brake pot 114 and for passing through the axle of the vehicle in the fully assembled state.

[0113] In this embodiment, the axle opening 162 is formed by axle openings 166, 168 formed coaxially to the brake system axis 118 in the friction discs 122, 124, wherein the respective axle opening 166, 168 of a friction disc 122, 124 extends from one flat side 132, 136 continuously through the friction disc 122, 124 to the other flat side 134, 138 through this friction disc 122, 124; also exemplarily in Fig. 5 shown.

[0114] The respective axle opening 166, 168 is bordered in the direction 163 radial to the brake system axis 118 by a respective edge section 172, 174, for example the axle opening 166 of the friction disc 122 is bordered by the edge section 172 and the axle opening 168 of the friction disc 124 is bordered by the edge section 174.

[0115] The brake ring 112 comprises a toothing 182 running circumferentially along the axle opening 162, which is designed in particular for the torque-transmitting connection with the brake pot 114; for example, among others, in the Fig. 2 and Fig. 5 shown.

[0116] The toothing 182 of the brake ring 112 is formed on the inner side 164 and there on an edge section, wherein in particular this edge section (favorably only) forms a part of the inner side.

[0117] In particular, the edge section (with the toothing) has an edge side. The edge side is (in particular only) a part of the radial inner side 164. In particular, the edge side is that side of the edge section (with the toothing) which is directed radially inward. Advantageously, the edge side delimits the axle opening 162 in the radial direction.

[0118] In this embodiment, the toothing 182 is formed on one of the friction discs, for example on the friction disc 122, by its edge portion 172 surrounding the axle opening 166.

[0119] The toothing 182 has teeth 184 which are arranged circumferentially, in particular periodically, on the axle opening 162 and here in particular on the axle opening 166 and project radially into the axle opening 162 and the axle opening 166 towards the brake system axis 118.

[0120] Between each two teeth 184, a recess 186 of the toothing 182 is formed, which recess has, in particular, a recess ridge 188. The recess ridge 188 delimits an open region of the recess 186, which opens into the axle opening 166 and thus into the axle opening 162, in the radial direction to the brake system axis 118.

[0121] In particular, each recess ridge 188 merges into a tooth flank 192 of an adjacent tooth 184, the tooth flanks 192 laterally delimiting the recess 186.

[0122] In particular, the teeth 184 project with a tooth front 193 radially into the axle opening 162 and a respective tooth flank 192 extends from the tooth front 193 radially, for example obliquely backwards, to a respective recess back 188 arranged circumferentially next to the tooth 184, as shown for example in Fig. 5 is shown.

[0123] Advantageously, at least some teeth 184 and thus also the tooth flanks 192 and tooth fronts 193 extend in the axial direction 155 to the brake system axis 118, for example at least approximately with an extent which corresponds to the thickness of the edge section of the friction disc 122 measured in the axial direction 155.

[0124] In particular, the edge portion 172, on which the toothing 182 is formed, extends in the axial direction 155 of the brake system axis 118 from a first axial end side 194 to a second axial end side 195.

[0125] In particular, the first axial end side 194 of the edge portion 172 is formed on an axial outer side, here on the axial outer side 152, of the brake ring 112.

[0126] In particular, the edge side of the edge portion 172 (with the toothing) extends in the axial direction 155 of the brake system axis 118 from a first axial end 196 to a second axial end 197, wherein the first axial end 196 is advantageously located on the first axial end side 194 of the edge portion 172 and the second axial end 197 is advantageously located on the second axial end side 195 of the edge portion 172.

[0127] Advantageously, the edge portion 172 (with the toothing 182) has a first transverse surface 198 on its first axial end side 195 and a second transverse surface 199 on its second axial end side 196.

[0128] In particular, the transverse surfaces 198, 199 extend radially outwards in the direction 163 radial to the brake system axis 118 and advantageously in the circumferential direction 165 around the axle opening 162 and in particular around the axle opening 166 on the circumferential side.

[0129] Preferably, the first transverse surface 198 extends radially outward from the first axial end 196 of the edge side. Preferably, the second transverse surface 199 extends radially outward from the second axial end 197 of the edge side.

[0130] Preferably, a normal of the respective transverse surface 198, 199 is aligned at least approximately perpendicular to the axial direction 155 of the brake system axis 118.

[0131] In some advantageous variants, the edge section 172 (with the toothing 182) is thicker, for example only slightly thicker, in the axial direction 155 of the brake system axis 118 than a region of the friction disc 122 located radially further outward relative to the brake system axis 118.

[0132] For example, at an outer radial end region of one of the transverse surfaces 198, 199, here for example at the first transverse surface 198, an axial step is formed on the corresponding flat side, here for example on the flat side 132, of the friction disc 122.

[0133] For example, a surface of the friction disc 122 (with the toothing 182), here for example the surface of the flat side 134, transitions from one of the transverse surfaces 198, 199, here for example from the second transverse surface 199, at least substantially continuously into a surface region of the radially outer and thinner section of the friction disc 122.

[0134] The brake pot 114 comprises in particular a mounting base 212, which is designed to mount and fasten the brake pot 114 to an axle of a vehicle, and a casing wall 214, which at least partially engages in the axle opening 162 of the brake ring 112 in the mounted state in order to form a connection between the brake ring 112 and the brake pot 114, as exemplarily shown, inter alia, in Fig. 1 and Fig. 6 is shown.

[0135] Preferably, the mounting base 212 and the casing wall 214, and in particular the entire brake pot 114, are formed integrally. Advantageously, the brake pot 114 is formed from a metallic material, for example, from a sheet metal.

[0136] The mounting base 212 has a mounting opening 222 formed coaxially with the brake system axis 118, through which a vehicle axle to which the brake pot 114 is to be or is to be mounted can be passed.

[0137] For example, the mounting base 212 is designed as a flat mounting disc.

[0138] Preferably, the mounting base 212 has fastening openings through which fastening means, for example screws, for fastening the brake pot 114 to an axle of a vehicle, for example to a fastening flange thereof, can be passed and are passed through in the fully assembled state.

[0139] The casing wall 214 extends circumferentially around the brake system axis 118. In particular, the casing wall 214 extends from the mounting base 212 in the axial direction 155 relative to the brake system axis 118.

[0140] In particular, the jacket wall 214 extends in the axial direction 155 of the brake system axis 118 from an arrangement end 225 to a free end 227.

[0141] In particular, the jacket wall 214 and the axial extension of the brake pot 114 end at the free end 227.

[0142] At the arrangement end 225, the jacket wall 214 is arranged indirectly and / or directly on the mounting base 212.

[0143] For example, a transition section 229 of the brake pot 114 is arranged between the mounting base 212 and the casing wall 214, connecting the two. In particular, the transition section 229 is arranged at the assembly end 225 of the casing wall 214 to the casing wall 214.

[0144] For example, the transition section 229 runs obliquely to the axial direction 155 of the brake system axis 118 and is in particular conical.

[0145] In other variants of the brake pot 114, the mounting base 212 is arranged directly at the arrangement end 225 of the casing wall 214 to the casing wall 214.

[0146] The brake pot 114 comprises a toothing 232 which is formed corresponding to the toothing 182 of the brake ring 112, wherein the toothing 232 is formed on the casing wall 214; shown by way of example, inter alia, in the Fig. 1, Fig. 2, Fig. 4, Fig. 6, Fig. 7 and Fig. 8.

[0147] With its toothing 232, the brake pot 114 is in engagement with the toothing 182 of the brake ring 112 and the edge portion 172 on which the toothing 182 is formed.

[0148] The toothing 232 has teeth 234 projecting radially outwards towards the brake system axis 118, and a recess 236 is arranged between each two adjacent teeth 234, as shown by way of example in Fig. 6 is shown enlarged.

[0149] The teeth 234 protrude radially with a tooth front 242 and tooth flanks 244 extend laterally from the tooth front 242 radially inward, for example obliquely, to a respective recess back 246 of the adjacent recesses 236.

[0150] The recess back 246 delimits the corresponding recess 236 in the radial direction 163 to the brake system axis 118 and respective tooth flanks 244 delimit the recess 236 laterally.

[0151] Preferably, the toothing 232 is formed from the casing wall 214. In particular, radially offset wall segments of the casing wall 214 form the tooth fronts 242 and recess backs 246, and wall segments extending obliquely thereto form the tooth flanks 244, wherein a respective obliquely extending wall segment connects a wall segment forming a tooth front 242 and a wall segment forming a recess back 246.

[0152] The teeth 234 of the toothing 232 are designed such that they engage in a respective recess 186 of the toothing 182 of the brake ring and the teeth 184 of the toothing 182 are designed such that they engage in a respective recess 236 of the toothing 232.

[0153] Preferably, a respective tooth flank 244 of the toothing 232 abuts against a corresponding tooth flank 192 of the toothing 182.

[0154] In particular, the engagement of the toothing 232 with the toothing 182 forms a torque-transmitting connection between the brake pot 114 and the brake ring 112.

[0155] The brake pot 114 projects with a projecting section 262 of its casing wall 214 from an axial outer side, here the axial outer side 152, of the brake ring 112 into the axle opening 162.

[0156] In particular, the second axial end side 195 of the edge portion 172 is located further away in the axial direction 155 of the brake system axis 118 from the axial outer side 152 of the brake ring 112, from which the brake pot 114 projects into the axle opening 162, than the first end side 194 of the edge portion 172.

[0157] In particular, the second axial end 197 of the edge side is located further away in the axial direction 155 of the brake system axis 118 from the axial outer side 152 of the brake ring 112, from which the brake pot 114 projects into the axle opening 162, than the first end 196 of the edge side.

[0158] In particular, the toothing 232 of the brake pot 114 is formed at least on the protruding portion 262 of the casing wall 214 and, for example, along at least substantially the entire axial extent of the casing wall 214.

[0159] Conveniently, the protruding portion 262 of the casing wall 214 abuts the edge portion 172 on which the toothing 182 of the brake ring 112 is formed. In particular, the protruding portion 262 abuts at least substantially against the edge portion 172 along the entire axial extent of the edge portion 172 between the two axial end sides 194, 195 of the edge portion 172.

[0160] In particular, the protruding portion 262 of the casing wall 214 and advantageously the entire brake pot 114 does not protrude beyond the edge portion 172 with the toothing 182 of the brake ring in the axial direction 155 of the brake system axis 118, i.e., in particular, not beyond the second axial end side 195 of the edge portion 172. The second axial end side 195 of the edge portion 172 is the axial end side 194, 195 of the edge portion 172 which, of the two axial end sides 194, 195 of the edge portion 172, is located further from the axial outer side 152, from which the brake pot 114, with its casing wall 214, protrudes into the axle opening 162.

[0161] In particular, the projecting portion 262 of the casing wall 214 and in particular the entire brake pot 114 does not project beyond the second transverse surface 199 (which is located on the second axial end side 195) of the edge portion 172 with the toothing 182 of the brake ring 112 in the axial direction 155 of the brake system axis 118.

[0162] Advantageously, the protruding section 262 of the casing wall 214 and in particular the brake pot 114 with the free end 227 of the casing wall 214 is flush with the second axial end side 195 of the edge section 172 (with the toothing 182 of the brake ring) and in particular flush with the second end 197 of the edge side (which is located on the second axial end side 197) and preferably flush with the second transverse surface 199 of the edge section 172 (which is located on the second axial end side 197).

[0163] Advantageously, a plurality of holding elements 312, 314 are provided to establish a connection between the brake pot 114 and the brake ring 112, by means of which the brake ring 112 is held by the brake pot 114.

[0164] In particular, the brake pot 114 comprises a plurality of holding elements 312 of a first group and a plurality of holding elements 314 of a second group. The holding elements 312 of the first group, on the one hand, and the holding elements 314 of the second group, on the other hand, are arranged offset from one another in the axial direction 155 relative to the brake system axis 118 and hold a portion of the brake ring 112 between them in order to advantageously prevent an axial relative displacement between the brake ring 112 and the brake pot 114.

[0165] In particular, the holding elements 312 of the first group are formed in recesses 236 of the toothing 232 of the brake pot 114.

[0166] Preferably, the holding elements 312 of the first group are each designed as an axial stop and in particular as a stop protruding from the recess back 246 into the open space of the recess 236.

[0167] In particular, the holding elements 312 of the first group are arranged on the casing wall 214 such that they abut the first axial end side 194 of the edge portion 172, here in particular an axial end 318 of a tooth 184 and / or the first transverse surface 198 of the edge portion 172. For example, the holding portions 312 of the first group abut an axial outer side, here the axial outer side 152, of the brake ring 112.

[0168] For example, the holding elements 312 of the first group are arranged in an axial central region 322 of the casing wall 214, wherein the axial central region 322 lies between the free axial end 227 of the casing wall 214 and the arrangement end 225 of the casing wall 214. In particular, the holding elements 312 of the first group rest against a respective holding surface 332 of the brake ring 112, in particular of the edge portion 172. These holding surfaces 332 of the first group are advantageously formed on the first axial end side 194 of the edge portion 172 and preferably by the first transverse surface 198 of the edge portion 172.

[0169] Conveniently, the holding elements 314 of the second group are arranged in a region axially offset from the region in which the holding elements 312 of the first group are arranged, here, the axial central region 322, in relation to the brake system axis 118. In particular, the holding elements 314 of the second group are arranged at the free axial end 227 of the casing wall 214.

[0170] Preferably, the holding elements 314 of the second group are arranged in recesses 236 of the toothing 232 and are advantageously formed from the recess back 246.

[0171] For example, a portion of the recess back 246 is pressed radially outward into the open space of the recess 236 as a holding portion 352 of the holding element 314.

[0172] Advantageously, fastening parts 354, 356 are formed from the casing wall 214 on both sides of the holding part 352 with respect to the direction of rotation 165. The fastening parts 354, 356 connect and fasten the holding part 352 on both sides with a tooth flank 244, which delimits the corresponding recess 236 in which the holding element 314 is formed.

[0173] In particular, the holding part 352 extends obliquely to the axial direction 155 of the brake system axis 118.

[0174] Preferably, the holding elements 314 of the second group rest on holding surfaces 362 of the edge portion 172 of the friction disc 122, wherein the holding surfaces 362 for the holding elements 314 of the second group are formed offset back to the second axial end side 194 of the edge portion 172 in the axial direction 155 of the brake system axis 118.

[0175] In particular, the holding surfaces 362 for holding elements 314 of the second group are formed on teeth 184 of the toothing 182 of the brake ring.

[0176] In this case, teeth 184 with a holding surface 362 of the second group are advantageously designed to be at least partially shortened, so that the holding surface 362 of the second group is axially set back from the second axial end side 197 of the edge portion 172. Thus, in particular, the teeth 184 with a holding surface 362 of the second group are designed to be shortened such that these teeth 184 at least partially do not extend in the axial direction 155 of the brake system axis 118 to the second axial end side 197 of the edge portion 172.

[0177] For example, the teeth 184 with a holding surface 362 of the second group have a notch 366 on the second axial end side 194, wherein the holding surface 362 is formed in the notch 366. Conveniently, the notch 366 opens into the axle opening 162 in the radial direction 163 of the brake system axis 118. In particular, the notch 366 is designed to open in the axial direction 155 of the brake system axis 118, specifically facing away from the axial outer side 152, from which the brake pot 114 projects into the axle opening 162.

[0178] For example, in some advantageous variants, the notch 366 is only partially formed on the end side 194 in the tooth 184 with the holding surface 362, so that, for example, flank sections 368 of the tooth 184 are also formed laterally of the notch 366 with respect to the direction of rotation 165. In particular, the flank sections 368 extend in the axial direction 155 of the brake system axis 118 up to the second transverse surface 199 on the second axial end side 194 of the edge section 172 and / or up to the second axial end 197 of the edge side. In particular, a tooth 184 with a holding surface 362 is designed to be shortened only in the region of the holding surface 362 and only partially. An example of such a variant is shown in the Fig. 5 shown.

[0179] In some advantageous variants, a tooth 184 with a holding surface 362 of the second group is designed to be at least substantially completely shortened, so that no section of the tooth 184 extends in the axial direction 155 of the brake system axis 118 up to the second transverse surface 199 on the second axial end side 195 of the edge section 172 and / or up to the second end 197 of the edge side. The representations in the figures can also be representative of such variants.

[0180] The holding surfaces 362 of the second group are in particular oriented away from the axial outer side 152, from which the brake pot 114 projects into the axle opening 162.

[0181] Advantageously, the holding surfaces 362 for holding elements 314 of the second group extend obliquely to the axial and radial directions relative to the brake system axis 118.

[0182] The holding elements 314 of the second group preferably rest with prestress on their holding surface 362 and / or are wedged therewith.

[0183] Conveniently, the holding elements 312 of the first group together with the holding elements 314 of the second group form a pre-stressed and / or self-locking connection by which the brake ring 112 is held on the brake pot 114.

[0184] Preferably, the holding elements 314 of the second group, in particular their respective holding part 352, with their extension extending away from the holding surface 362, stand at least approximately perpendicularly on the obliquely extending holding surface 362.

[0185] In particular, the extension of the holding part 352 extending away from the holding surface 362 runs at least substantially perpendicular to a transverse direction in which the two fastening parts 354, 356 are fastened to the holding part 352.

[0186] In particular, a structure, a mode of operation and, for example, advantages of the braking system 100 are briefly summarized as follows.

[0187] The brake pot 114 can be mounted on an axle of a vehicle, in particular by means of the mounting base 212, and the brake ring 112 with its friction surfaces 156 and 158 can, for example, interact with brake linings of brake shoes in a braking manner, wherein the braking effect is transmitted via the brake pot 114 to the axle of a vehicle via the torque-transmitting connection between the brake ring 112 and the brake pot 114, in particular via the intermeshing toothing 182 and toothing 232.

[0188] For axial securing of the brake ring 112 relative to the brake pot 114, holding elements 312, 314 are provided in particular.

[0189] In particular, the brake ring 112, in particular the edge portion 172 of the friction disc 122, is held between the holding elements 312 of the first group and the holding elements 314 of the second group.

[0190] Preferably, at least some retaining surfaces, in particular the retaining surfaces 362 for the retaining elements 314 of the second group, extend obliquely to the axial direction of the brake system axis 118. For example, the retaining elements 314 can thus be applied in a self-locking manner to the corresponding obliquely extending retaining surface 362 and, for example, wedged thereto. This advantageously enables a play-free connection between the brake ring 112 and the brake cup 114.

[0191] Advantageously, the brake pot 114, in particular with its section 262 projecting into the axle opening 162, does not protrude in the axial direction 155 of the brake system axis 118 beyond the edge section 172 with which the brake pot 114 is in engagement.

[0192] In particular, the brake pot 114, in particular its projecting portion 262, and the brake ring 112, in particular its edge portion 172, are in engagement with their toothing 232 and toothing 182.

[0193] Advantageously, the protruding portion 262 of the brake pot 114 is flush with the second axial end side 195 of the edge portion 172 (which has the toothing 182) in the axial direction 155 of the brake system axis 118 and in particular is flush with a second transverse surface 199 on the second axial end side 197.

[0194] Advantageously, material can be saved in the brake pot 114, since no material is required for sections projecting beyond the edge section 172.

[0195] In particular, an effective and / or efficient solution is provided in this way, since the brake pot 114, with its section 262 projecting into the axle opening 162, is at least largely in engagement with the brake ring 112.

[0196] Advantageously, the edge portion 172 (with which the brake pot 114 is engaged) has holding surfaces 362 for holding elements 314 (in particular of a second group), wherein these holding surfaces 362 are arranged set back in the axial direction 155 of the brake system axis 118 to the second axial end 197 of the edge portion and / or the second transverse surface 199 on the second end side 195 of the edge portion 195 and are oriented in the axial direction 155 in an opposite direction to the axial outer side 152, from which the brake pot 114 projects into the axis opening 162.

[0197] Advantageously, these recessed holding surfaces 362 make it possible for holding elements 314 (for example of a second group) to bear against these recessed holding surfaces 362 and yet the brake pot 114 does not protrude beyond the edge section 172 in the axial direction 155.

[0198] Advantageously, the recessed retaining surfaces 362 are formed on teeth 184 of the toothing 182 of the edge portion 172.

[0199] In some inexpensive variants, the brake ring 112 has several cooling channels 142.

[0200] For example, at least some cooling channels 142 extend at least partially along a flat side 134 of a friction disc 122, which has the edge portion 172 with which the brake pot 114 is engaged.

[0201] In particular, an advantage of the brake pot 114 not projecting beyond the edge section 172 is that a cooling air flow 376 can flow radially outwards from the axle opening 162 to the brake system axis 118 into the cooling channels 142 (or vice versa from a cooling channel 142 into the axle opening 162) and the flow of the cooling air flow 376 is at least substantially not impeded by the brake pot 114 and, in particular, no section of the brake pot 114 projecting beyond the edge section 172 impairs a flow of the cooling air flow 376.

[0202] In particular, the brake system 100 and in particular the connection between the brake ring 112 and the brake pot 114 can be constructed in a simple manner.

[0203] For example, the brake pot 114 with the not yet formed holding elements 314 of the second group is inserted into the axle opening 162 with the free axial end 227 of the casing wall 214 first.

[0204] The holding elements 312 of the first group in the axial central region 322 are in particular already formed and thus form a stop during insertion for the correct axial alignment of the brake pot 114 relative to the brake ring 112 in relation to the brake system axis 118.

[0205] In variants in which the holding elements 312 of the first group forming the stops are formed at the free axial end 324, the brake pot 114 is inserted into the axle opening with its axially opposite end, on which in particular the mounting base 212 is arranged, until the holding elements 312 come into contact with their corresponding holding surfaces 332. In particular, the holding surfaces 332 are then formed in the axial direction 155 of the brake system axis 118 offset back to the second axial end 197 of the edge side and / or offset back to the second transverse surface 199 on the second end side 195 of the edge section 172.

[0206] If the brake pot 114 is then correctly positioned relative to the brake ring 112, the holding element 314 can be formed in an assembly step by radial forming and, at the same time as forming, can be applied to the holding surface 362.

[0207] For example, the radial shaping and application of the holding elements 314 of the second group is carried out with a slide tool acting in the radial direction and preferably in a force-controlled manner.

[0208] Preferably, it is provided that a holding element 312 of the first group is arranged alternately in the recesses 236 and a holding element 314 of the second group is arranged in the subsequent recess 236.

[0209] In variants of the exemplary embodiment, it is provided, for example, that both a holding element 312 of the first group and a holding element 314 of the second group are formed in at least some recesses 236.

[0210] In some variants of the embodiment, it is provided that no holding element 312, 314 is formed in some recesses 236.

[0211] In a further exemplary embodiment 100' of a braking system, those features and / or elements which are at least substantially identical in design and / or perform at least substantially the same function as features and / or elements in the first exemplary embodiment are provided with the same reference numerals. Unless more detailed information and / or deviating information is provided regarding such features and / or elements in connection with this further exemplary embodiment, reference is made in full to the explanations in connection with the first exemplary embodiment with regard to advantageous embodiments of these elements and / or features.

[0212] By way of example, a variant of the further embodiment of a braking system 100' is shown in detail in the Fig. 9 shown.

[0213] The brake system 100' comprises a brake ring 112 and a brake pot 114.

[0214] The brake ring 112 comprises a friction disc 122 and in particular only exactly one friction disc 122. Advantageously, the friction disc 122 has two flat sides 132, 134 which are opposite sides in an axial direction 155 to a brake system axis 118.

[0215] Advantageously, at least one flat side, here for example the flat side 132, of the friction disc 122 at least partially forms an axial outer side 152 of the brake ring 112.

[0216] Advantageously, a brake pad 382 is arranged on at least one flat side 132, 134 of the friction disc 122.

[0217] Advantageously, the brake pad 382 is arranged on the flat side 134, wherein this flat side 134 is a side opposite to the flat side 132 in the axial direction 155, which at least co-forms an outer side 152 of the brake ring 112.

[0218] Advantageously, the brake pad 382 is arranged on an axial outer side 154 and / or at least forms an axial outer side 154.

[0219] In particular, the brake pad 382 forms a friction surface 158 of the brake ring 112. Advantageously, a further friction surface 156 is provided, which is formed in the axial direction 155 opposite to the friction surface 158 of the brake pad 382. Advantageously, the two friction surfaces 156, 158 each at least partially form a respective axial outer side 152, 154.

[0220] For example, in some variants, the further friction surface 156 (which is located axially opposite to the friction surface 158 of the brake pad 382) is formed by the friction disc 122, in particular at least a region of its flat side 132 (as shown by way of example in the Fig. 9).

[0221] For example, in some variants, the further friction surface 156 is formed by a brake pad material, which is preferably arranged on the flat side 132 of the friction disc 122.

[0222] The friction disc 122 comprises an axle opening 166, which at least partially forms the axle opening 162.

[0223] The friction disc 122 comprises an edge portion 172, which extends in a circumferential direction 165 around the axle opening 166 and thus around the axle opening 162 and delimits the axle opening 166 in the radial direction 163 relative to the brake system axis 118. Thus, the edge portion 172 delimits the axle opening 162 at least partially in the radial direction 163.

[0224] In some advantageous variants, the edge section 172 of the friction disc 122 is collar-shaped and projects in the axial direction 155 of the brake system axis 118 beyond a radially further outwardly located surface area of the flat side 132, wherein this flat side 132 advantageously at least partially forms an axial outer side 152. Such a variant is exemplified in the Fig. 9 shown.

[0225] In particular, an axial step is formed on a radial outer region of the edge portion 172.

[0226] In other advantageous variants, the flat side 132 also runs in the region of the edge section 172 at least substantially flat and level radially inwards up to the axis opening 166. The representation in the Fig. 9 be representative.

[0227] The brake ring 112 has a toothing 182. Advantageously, the toothing 182 is formed on the edge portion 172 of the friction disc 122.

[0228] In particular, the toothing 182 of the brake ring 112 comprises a plurality of teeth 184 and recesses 186. In particular, a respective recess 186 is located between each two teeth 184. Advantageously, the toothing 182 is formed at least partially as explained in the first embodiment.

[0229] The brake pot 114 conveniently includes a mounting base 212.

[0230] The brake pot 114 comprises a casing wall 214, and the brake pot 114 projects into the axle opening 162 at least with a projecting portion 262 of the casing wall 214. In particular, the brake pot 114 projects into the axle opening 162 from an axial outer side, here from the axial outer side 152.

[0231] The protruding portion 262 of the brake cup 114 advantageously has a toothing 232. Advantageously, the toothing 232 comprises a plurality of teeth 234 and recesses 236. In particular, a respective recess 236 is located between each two teeth 234. Advantageously, the toothing 232 of the brake cup 114 is at least partially configured as explained in connection with the first embodiment.

[0232] In particular, the edge portion 172, in particular with its toothing 182, and the protruding portion 262 of the brake pot 114, in particular with its toothing 232, are in engagement with each other.

[0233] In particular, the protruding portion 262 of the brake pot 114 and in particular the entire brake pot 114 does not protrude beyond the edge portion 172 in the axial direction 155 of the brake system axis 118 (in particular starting from the axial outer side 152, from which the brake pot 114 engages into the axis opening 162).

[0234] In particular, the protruding portion 262 does not protrude in the axial direction 155 beyond a second axial end 197 of an edge side of the edge portion 172, wherein the second axial end 197 of the edge side of two axial ends 196, 197 of the edge side is the axial end which is further away from the axial outer side 152, from which the brake pot 114 protrudes into the axle opening 162.

[0235] For example, the edge portion 172 has a first transverse surface 198 on its first axial end side 194.

[0236] In particular, the edge portion 172 has a second transverse surface 199 on its second axial end side 195.

[0237] Preferably, the brake pot 114, in particular with its projecting section 162, is flush with the second axial end 197 of the edge side and / or with the second transverse surface 199 of the edge section 172.

[0238] In particular, a plurality of holding elements 312 and 314 are provided for axially securing the brake ring 112 and the brake pot 114 relative to one another.

[0239] For example, the holding elements 312, 314 are formed from the jacket wall 214 of the brake pot 114. Advantageously, the holding elements 312, 314 are formed at least partially as explained in connection with the first embodiment.

[0240] In particular, the edge portion 172 forms holding surfaces 332, 362 for the holding elements 312, 314.

[0241] Advantageously, the holding surfaces 332, 362 are at least partially formed as explained in connection with the first embodiment.

[0242] For example, the holding surfaces 332 for holding elements 314 of a first group are formed on a first transverse surface 198 of the edge portion 172. In particular, these holding surfaces 332 of the first group and the first transverse surface 198 of the edge portion 172 at least face the outer side 152, from which the brake pot 114 projects into the axle opening 162, and are formed, for example, on this axial outer side 152.

[0243] In particular, holding surfaces 362 for holding elements 314 of a second group are oriented opposite to the axial outer side 152, from which the brake pot 114 projects into the axle opening 162. Advantageously, these holding surfaces 362 of the second group are arranged set back in the axial direction 155 of the brake system axis 118 from the second axial end 197 of the edge side and / or from the second transverse surface 199 on the second axial end side 195.

[0244] Advantageously, a respective holding element 314 of the second group can thus rest against a corresponding holding surface 362 and the brake pot 114 nevertheless does not protrude axially beyond the edge section 172.

[0245] In particular, an advantage of the described solution is that the brake pad 158 can be pulled radially further inwards in the direction 163 radial to the brake system axis 118, since in particular the projecting section 262 does not project axially beyond the edge section 172.

[0246] In particular, as an advantage of the described solution, a risk is at least reduced or, for example, a danger is eliminated that, when the brake pad 158 wears, a projecting section of the projecting section 262 of the brake pot 114 protrudes in the axial direction 155 beyond the (in particular worn) brake pad 382 and thus complications may arise.

[0247] Furthermore, the described exemplary embodiments are preferably designed at least partially as explained in connection with the other exemplary embodiments, so that with regard to details not explained in more detail in one exemplary embodiment, reference is made in full to the explanations in connection with the other exemplary embodiments.
