According to the invention a high efficiency can be obtained. do not deposit or deposit a minimum of dirt on the ABS ring in order to prevent dirt on the ABS ring from rendering useless signals that a corresponding ABS sensor receives. outer ring of a roller bearing, dirt that is between the ABS ring and a roller bearing seal can always come out through the through-holes of the ABS ring as these through-holes are never clogged with dirt, as dirt is deflected from the surface area. Especially it can prevent premature bearing failure. Moreover, it can mainly prevent dirt adhering to the ABS ring from damaging the ABS sensor.

[0006] Vantajosamente a área de superfície com alumínio no estado seco apresenta um coeficiente de atrito estático que é inferior a 0,1, preferivelmente inferior a 0,07 e especialmente preferivelmente inferior a 0,03.[0006] Advantageously, the surface area with aluminum in the dry state has a coefficient of static friction which is less than 0.1, preferably less than 0.07 and especially preferably less than 0.03.

[0007] Preferivelmente uma gota de água com a área de superfície forma um ângulo de contato de pelo menos 110°.[0007] Preferably a water droplet with surface area forms a contact angle of at least 110°.

[0008] Especialmente preferivelmente uma gota de água forma com a área de superfície um ângulo de contato de pelo menos 125°, especialmente de pelo menos 140°.[0008] Especially preferably a drop of water forms with the surface area a contact angle of at least 125°, especially of at least 140°.

[0009] Vantajosamente a área de superfície é superhidrofóbica. Entende-se por uma “área de superfície superhidrofóbica” especialmente uma área de superfície sobre a qual uma gota de água inclui um ângulo de contato superior a 160° com a área de superfície, sendo que preferivelmente a área de superfície é basicamente plana, especialmente preferivelmente plana, e preferivelmente a área de superfície apresenta a mesma constituição e preferivelmente a área de superfície em caso de medição do ângulo de contato é alinhada em sentido horizontal.[0009] Advantageously the surface area is superhydrophobic.

[0011] Vantajosamente a área de superfície apresenta um limiar de um furo de passagem do anel ABS.[0011] Advantageously, the surface area has a threshold of a through hole of the ABS ring.

[0016] A figura 2 mostra um corte ampliado da figura 1,[0016] Figure 2 shows an enlarged section of figure 1,

[0017] A figura 3 mostra uma ilustração da definição do ângulo de contato,[0017] Figure 3 shows an illustration of the definition of the contact angle,

[0018] A figura 4 mostra um corte parcial através de uma parte de um dispositivode rolamento com um exemplo de modalidade alternativo de um anel ABS,[0018] Figure 4 shows a partial section through a part of a bearing device with an alternative embodiment example of an ABS ring,

[0019] A figura 5 mostra um anel ABS por último mencionado.[0019] Figure 5 shows a last mentioned ABS ring.

[0020] A figura 1 mostra um corte parcial através de uma parte de um dispositivode rolamento com um rolamento de rolo, que é projetado como rolamento de rolo cônico de duas carreiras. O rolamento de rolo apresenta um primeiro elemento de rolamento 10, que é projetado como anel externo e um segundo elemento de rolamento 12, que é projetado como anel interno. O anel externo fica apoiado de modo girável em relação ao anel interno. O dispositivo de rolamento apresenta uma unidade de vedação 14 com um elemento de fixação 16. O elemento de fixação fixa um elemento de vedação 18 da unidade de vedação no primeiro elemento de rolamento.[0020] Figure 1 shows a partial section through a part of a rolling device with a roller bearing, which is designed as a double row tapered roller bearing. The roller bearing has a first bearing element 10 which is designed as an outer ring and a second bearing element 12 which is designed as an inner ring. The outer ring is rotatably supported in relation to the inner ring. The bearing device has a sealing unit 14 with a fastening element 16. The fastening element fixes a sealing element 18 of the sealing unit to the first bearing element.

[0021] O elemento de fixação 16 é um elemento de chapa metálica de formato anular e é fixado em união positiva no anel externo, sendo que uma superfície total do elemento de chapa metálica é revestida com PTFE. Além disso, o elemento de fixação 16 forma um anel ABS 20 de acordo com a invenção. O anel ABS apresenta furos de passagem 22 que ficam dispostos ao longo de uma direção circunferencial do anel ABS equidistantes entre si. O elemento de chapa metálica total é revestido com PTFE. O dispositivo de rolamento é projetado como rolamento de roda de um caminhão. O anel ABS fica disposto em um lado frontal 24 do anel externo. O lado frontal fica disposto em relação a um lado, que é previsto para a fixação de uma roda. Para a fixação da roda o dispositivo de rolamento apresenta meios de fixação 32.[0021] The fastening element 16 is an annular-shaped sheet metal element and is fixed in positive union on the outer ring, with an entire surface of the sheet metal element coated with PTFE. Furthermore, the fastening element 16 forms an ABS ring 20 according to the invention. The ABS ring has through holes 22 which are arranged along a circumferential direction of the ABS ring equidistant from each other. The total sheet metal element is PTFE coated. The bearing device is designed like a truck wheel bearing. The ABS ring is arranged on a front side 24 of the outer ring. The front side is arranged in relation to a side which is provided for fixing a wheel. For fixing the wheel, the rolling device has fixing means 32.

[0022] Além disso, o dispositivo de rolamento apresenta um elemento estrutural 28 que é fixado no anel interno. Uma primeira borda de vedação 26 e uma outra borda vedação do elemento de vedação 18 ficam adjacentes ao elemento estrutural 28. Essas duas bordas de vedação se estendem basicamente na direção radial do dispositivo de rolamento. Além disso, o elemento de vedação 18 apresenta duas outras bordas de vedação, que se estendem basicamente na direção axial do dispositivo de rolamento e ficam adjacentes ao elemento estrutural 28. O elemento de vedação 18 é fixado em uma área 30 do elemento de fixação que saindo do anel ABS se estende radialmente para dentro.[0022] In addition, the bearing device features a structural element 28 which is fixed to the inner ring. A first sealing edge 26 and a further sealing edge of the sealing member 18 are adjacent to the structural member 28. These two sealing edges basically extend in the radial direction of the bearing device. Furthermore, the sealing element 18 has two other sealing edges, which extend basically in the axial direction of the bearing device and are adjacent to the structural element 28. The sealing element 18 is fixed in an area 30 of the fastening element that coming out of the ABS ring extends radially inward.

[0023] A unidade de vedação veda o rolamento de rolo em relação à saída de lubrificante e em relação à entrada de impurezas.[0023] The sealing unit seals the roller bearing from the outflow of lubricant and from the ingress of impurities.

[0024] Em um estado montado o dispositivo de rolamento é parte de um caminhão. O caminhão apresenta um elemento de sensor, que fica disposto frente ao anel ABS. O anel ABS gera um campo magnético que é capturado pelo elemento de sensor quantitativamente. Se o anel externo girar e com isso girar o anel ABS com relação ao elemento sensor, então o elemento sensor detectará um campo magnético que se altera periodicamente com base nos furos de passagem. Com base nesse campo magnético uma unidade de cálculo do caminhão calcula uma velocidade de giro e um número de revoluções e uma aceleração do anel externo.[0024] In an assembled state the rolling device is part of a truck. The truck features a sensor element, which is arranged in front of the ABS ring. The ABS ring generates a magnetic field that is captured by the sensor element quantitatively. If the outer ring rotates and thereby rotates the ABS ring with respect to the sensing element, then the sensing element will detect a magnetic field that changes periodically based on the through holes. Based on this magnetic field a truck calculation unit calculates a turning speed and a number of revolutions and an outer ring acceleration.

[0025] Na fabricação do dispositivo de rolamento o elemento de fixação junto ao qual o elemento de vedação 18 é fixado, é fixado no anel externo.[0025] In the manufacture of the bearing device, the fastening element next to which the sealing element 18 is fastened, is fastened to the outer ring.

[0026] A figura 3 mostra uma ilustração do ângulo de contato Φ sendo que uma gota de água é representada sobre uma superfície horizontal, não de acordo com a invenção.[0026] Figure 3 shows an illustration of the contact angle Φ where a drop of water is represented on a horizontal surface, not according to the invention.

[0027] Alternativamente é viável que uma parte do elemento de chapa metálica ou todo o elemento de chapa metálica, ao invés de ser revestido com PTFE seja revestido com um revestimento de carbono quase sem atrito.[0027] Alternatively it is feasible that a part of the sheet metal element or the entire sheet metal element, instead of being coated with PTFE, is coated with an almost frictionless carbon coating.

[0028] Além disso, é a princípio viável que o anel ABS ao invés dos furos de passagem apresente cavidades ou elevações.[0028] In addition, it is, in principle, feasible that the ABS ring instead of the through holes presents cavities or elevations.

[0029] Nas figuras 4 e 5 é representado um exemplo de modalidade alternativo. Basicamente componentes, características e funções consistentes são computados a princípio com os mesmos sinais de referências. Para a diferenciação dos exemplos de modalidade, porém são adicionados, porém ao sinal de referência do exemplo de modalidade na figura 4 e 5 a letra “a”. A descrição a seguir limita-se basicamente à diferença em relação ao exemplo de modalidade nas figuras1 a 3, sendo que com relação a componentes estáveis, características e funções pode ser feita referência à descrição do exemplo de modalidade nas figuras 1 a 3.[0029] In figures 4 and 5 an example of alternative modality is represented. Basically, consistent components, features and functions are computed in principle with the same reference signs. To differentiate the modality examples, however, the letter “a” is added to the reference sign of the modality example in figures 4 and 5. The following description is basically limited to the difference from the modality example in figures 1 to 3, whereas with regard to stable components, features and functions reference can be made to the description of the modality example in figures 1 to 3.

[0030] A figura 4 mostra um dispositivo de rolamento com um exemplo de modalidade alternativo de um anel ABS 20a. O anel ABS 20a é fixado em união positiva a uma parte de um perímetro externo de um elemento estrutural 10a projetado como anel externo. A sujeira, que se acumula entre uma unidade de vedação 14a e o anel ABS pode sair pelos furos de passagem 22a em sentido radial para fora.[0030] Figure 4 shows a bearing device with an alternative embodiment example of an ABS ring 20a. The ABS ring 20a is secured in positive union to a portion of an outer perimeter of a structural member 10a designed as an outer ring. Dirt, which accumulates between a sealing unit 14a and the ABS ring, can exit through the through holes 22a radially outwards.
