Definitions
- the invention relates to a brake arrangement, in particular for a wheel of a motor vehicle.
- the braking energy is increasingly recovered through recuperation in order to increase energy efficiency. It is also the goal that the driving resistances in such motor vehicles are further reduced in order to increase energy efficiency. With regard to the driving resistance, an attempt is made to further reduce the residual torque on the brake calipers. Due to the more frequent recuperation, the wheel brakes are used less and less, which has the disadvantage that the brakes are no longer constantly ground free, which means that, depending on the weather and climatic conditions, the friction value of the brakes can be greatly reduced and, in extreme cases, the brakes can also rot or freeze.
- a significant reduction in fine dust emissions can be achieved.
- An exemplary embodiment of the invention relates to a brake arrangement, in particular of a wheel of a motor vehicle, with a first brake disc and with a second brake disc, which are arranged at a distance from one another and are connected to one another in a rotationally fixed manner and which can be rotated about a common axis of rotation, in particular on a wheel carrier, can be arranged, wherein A brake caliper with brake pistons is arranged axially between the two brake discs, with at least one first brake piston being provided, by means of which a first arranged brake pad can be applied against the first brake disc, and wherein optionally a second brake piston is provided, by means of which a second arranged brake pad can be pressed against the second
- brake disc can be acted upon or at least one first brake piston is provided, by means of which a first arranged brake pad can be acted upon against the first brake disc and by means of which a second arranged brake pad can be acted upon at least indirectly against the second brake disc, the brake caliper having a base body and/or cover , which covers the two brake discs radially on the outside like a cover and shields the space between the brake discs to the outside.
- first brake piston acts on the first brake pad against the first brake disc and the reaction force presses the frame on the opposite side against the second brake pad and presses it against the second brake disc applied.
- the brake discs have inner surfaces facing towards one another and outer surfaces facing away from one another, the brake linings of the brake pistons only acting against the inner surfaces of the brake discs facing towards one another.
- the respective brake disc is only on one side, the inside, for Brakes are applied so that the resulting brake dust can collect in the space between the brake discs and can be specifically collected and stored without brake dust being able to escape in large quantities.
- the outer surfaces of the brake discs or at least one outer surface of a brake disc are used for cooling and/or to increase the flexural rigidity by providing ribs on the outer surface of the brake disc to improve cooling and/or to increase the flexural rigidity of the brake disc.
- This increases the rigidity, since the brake discs are only braked on one side.
- the cooling of the brake and the cooling fluid used can also be improved in this way.
- the cooling fluid is air.
- an abutment acts on the outer surface of at least one of the brake discs or on both brake discs, in order to axially support the brake disc against axial bending.
- the rigidity can be further increased in order to reduce flexing of the brake discs.
- a labyrinth seal is provided between the base body and/or the cover and the radial outer area of the brake discs or at least one brake disc in order to seal off the space between the two brake discs. This ensures that brake dust can only escape to an insignificant extent.
- the base body and/or the cover and/or the brake caliper is provided with cooling air ducts and/or cooling air openings for introducing and/or conducting cooling air.
- the cooling of the brake assembly can thus be improved, in particular due to the air conveyance effects of the brake discs themselves.
- a brake dust collection and storage arrangement is provided on the base body and/or on the cover or adjacent thereto, by means of which brake dust can be collected and stored. This means that the brake dust is stored in a spatially limited manner and is not distributed evenly in the space between the two brake discs, so that the stored brake dust can also be removed during a service. In this way, the brake dust can be disposed of properly and is not released into the environment in an uncontrolled manner.
- the brake dust collecting and storage arrangement is fastened to the base body, the cover and/or the wheel carrier by means of at least one holder or is formed by the base body, the cover.
- a permanently secure arrangement and/or integration can thus be achieved.
- the brake dust collecting and storage arrangement has a mesh, in particular a metal mesh, which is designed in particular to be exchangeable in order to store the brake dust. As a result, a store for the brake dust can be created at low cost.
- the brake dust collecting and storage arrangement has a collecting plate running essentially in the circumferential direction, which is designed in particular to be exchangeable in order to collect the brake dust. This allows the brake dust to be collected in a targeted manner.

- FIG. 1 shows a brake arrangement 1 of a wheel of a motor vehicle in a schematic partial sectional view, with a rim 3 of a wheel 4 being recognizable on the wheel carrier 2 .
- the motor vehicle is in particular a motor vehicle with an internal combustion engine, with a purely electric drive (BEV) or as a flybrid vehicle with an internal combustion engine and an electric motor as drive motors (FIEV, PHEV).
- BEV purely electric drive
- FIEV flybrid vehicle with an internal combustion engine
- PHEV electric motor as drive motors
- PHEV stands for a plug-in hybrid vehicle.
- the brake assembly 1 has a first brake disc 5 and a second brake disc 6, which are arranged spaced apart from one another and are connected to one another in a rotationally fixed manner and which can be rotated about a common axis of rotation, in particular on a wheel hub 29, can be arranged.
- a space 7 is left between the two brake disks 5, 6, in which the brake caliper 8 with the brake pistons 9 is arranged.
- a brake caliper 8 with at least one brake piston 9 is arranged axially between the two brake discs 5 , 6 .
- At least one first brake piston 9 is provided, by means of which a first arranged brake pad 10 can be acted upon against the first brake disc 5, and at least one second brake piston 9 is also provided, by means of which a second arranged brake pad 11 can be acted upon against the second brake disc 6.
- the brake caliper 8 is carried by the wheel carrier 2 .
- a back plate 12 is provided between the brake pistons 9 and the respective brake lining 10, 11 in order to equalize the contact pressure force from the brake pistons 9 on the brake lining 10, 11.
- the brake caliper 8 has a base body 13 and/or cover 14, which covers the two brake discs 5, 6 radially on the outside like a cover and shields the spatial area 7 between the brake discs 5, 6 from the outside.
- the spatial area 7 with the units and components arranged therein is protected from the weather, dirt and climate and brake dust cannot escape with difficulty.
- this type of encapsulation also concentrates the frictional heat generated.
- the base body 13 and the cover 14 can also be combined.
- a brake disc 5 or at least one outer surface 16 of a brake disc 5, 6 is used for cooling and/or to increase the flexural rigidity of the brake disc 5, 6 by providing ribs 17 on the outer surface 16 of the brake disc 5, 6 to improve cooling and/or to increase the flexural rigidity of the brake disc 5, 6 are provided.
- FIG. 4 shows an alternative view without ribs, with an abutment 18 acting on the outer surface 16 of at least one of the brake discs 5, 6 or on both brake discs 5, 6 for axially supporting the brake disc 5, 6 against axial bending.
- the abutment 18 is supported on the brake caliper 8 or on the base body 13 of the brake caliper 8.
- the abutment 18 can be designed as a floating caliper, for example. However, the design with an abutment 18 can also be provided in combination with the ribs 17 according to FIG.
- Figure 1 also shows that a labyrinth seal 19 is provided between the base body 13 and/or the cover 14 and the radial outer area of the brake discs 5, 6 or at least one brake disc 5, 6 in order to seal off the spatial area 7 between the two brake discs 5, 6 .
- Figures 2, 3, 5 and 7 to 10 show different exemplary embodiments of brake assemblies 1 in different representations, in which the base body 13 and/or the cover 14 and/or the brake caliper 8 is/are provided with cooling air ducts 20 and/or cooling air openings 21. are for introducing and/or passing through cooling air.
- air can pass through the brake caliper 8 into the spatial area 7 and there flow through the brake lining 10, 11, the brake disc 5, 6 and the brake caliper 8 itself or flow past it in order to bring about effective brake fluid cooling.
- the fluid path of the air can be approximately S-shaped, see Figure 7 or 8.
- the air can flow into various cooling air openings 21 and then be bundled in cooling air ducts 20 and passed on.
- the cover 14 can be designed in such a way that cooling air ducts 20 are redirected, or additional elbows 28 can be used.
- Grooves 30, which allow cooling air to flow through can also be provided in the brake discs 5, 6, see for example Figure 6.
- the grooves 30 are separated from one another by webs 22, the design of the grooves 30 or the webs 22 being curved forwards, backwards, radially or can be designed and arranged concentrically. An air conveying effect is achieved by the webs 22 in order to allow the cooling air to flow through the grooves 30 .
- the webs 22 and the grooves 30 can be provided on one side of the brake discs 5, 6 or on both sides of the brake discs 5, 6. This also ensures that penetrating water or dirt does not get into the area of the brake pads 10, 11 and the corresponding friction surfaces. In an advantageous exemplary embodiment, see for example FIG.
- a brake dust collection and storage arrangement 23 can be provided on the base body 13 and/or on the cover 14 or adjacent thereto, by means of which brake dust can be collected and stored. It is also expedient, see FIG. 5, if the brake dust collecting and storage arrangement 23 is fastened to the cover and/or the wheel carrier by means of at least one flapper 27 or is formed by the wheel carrier or the cover.
- the brake dust collecting and storage arrangement 23 can have a mesh 24, in particular a metal mesh, which is designed in particular to be exchangeable in order to store the brake dust.
- the brake dust collecting and storage arrangement 23 can also have a collecting plate 25 running essentially in the circumferential direction, which is designed in particular to be exchangeable in order to collect the brake dust.
- the collecting plate 25 advantageously closes off the spatial area 7 radially and axially to the outside and rests tightly on the brake caliper 8 on a sealing surface 26 or on sealing surfaces 26 .
- the brake pistons 9 are advantageously only working under pressure and can be designed as a multi-piston fixed caliper design or as a floating piston design with primarily one brake piston 9 or with several brake pistons 9. It is also advantageous that the brake caliper 8 radially occupies a partial segment of the friction pairing working space between the brake disc 5, 6 and brake pad 10 , 11 can seal as a kind of labyrinth seal, so that the emission of brake dust is further limited.
- Figures 11 and 12 show a further exemplary embodiment of a brake disc 5, 6, which is designed in such a way that it has annularly arranged webs 22 on its outside, which separate grooves 30 from one another, so that a fluid flow 32 flows from the radially inside and in the axial direction can, which can flow along the brake disc 5, 6 radially outward between the webs 22 through the grooves 30.
- a ring-shaped cover part 31 is provided radially on the outside of the brake disc 5, 6 in such a way that it is arranged at a distance from the brake disc 5, 6, so that the fluid flow 32 between the cover part 31 and the brake disc 5, 6 can flow radially outward. It can be seen in FIG.
- cover part 31 is set conically and approaches the brake disc 5, 6 from radially inside to radially outside and still leaves a gap or distance radially outside to allow the fluid flow 32 to flow away.
- the webs 22 are advantageously curved forwards or alternatively backwards curved or radially aligned.
- the cover part 31 is optionally designed and/or connected to be heat-conducting in order to be able to dissipate heat better.
