Abstract

aperfeiçoamento em disco de freio automotivo, fabricado em peça única de ferro fundido cinzento, formado por um cubo cilindrico (1), distanciador, tendo uma extremidade flangeada em perfil peculiar (2), ordinariamente dentado, onde cada dente é vazado por furo (3) de fixação do conjunto no local de uso, enquanto pela extremidade oposta dito cubo cilindrico (1) está integrado com um par de discos paralelos (4 e 5), espaçados por aletas radiais de ventilação (6); ditos discos (4-5) possuem faces ou lados expostos que configuram pistas (7) para contato das pastilhas de frenagem; dita.s pistas (7) são lavradas com pluralidade de cavidades não passantes (8) distribuídos aleatoriamente ou em carreiras .com vários deles alinhados e de acordo com um espaçamento adequado, porém, em qualquer distribuição, ditas cavidades conferem meios para o armazenagem temporária do plasma criado entre as pistas (7) dos discos (4 e 5) e a superfície da pastilha de freio no momento da frenagem, deixando que toda a área de contato da pastilha de freio atrite com as referidas pistas (7) dos discos de freio; entre tais furos (8) e em quantidade menor, são distribuídos também vários minúsculos canais limpa pastilhas ligeiramente arqueados (9).improvement in automotive brake disc, manufactured in a single piece of gray cast iron, formed by a cylindrical hub (1), spacer, having a flanged end in a peculiar profile (2), ordinarily toothed, where each tooth is cast by hole (3 ) fixing the set at the place of use, while at the opposite end said cylindrical hub (1) is integrated with a pair of parallel discs (4 and 5), spaced apart by radial ventilation fins (6); said discs (4-5) have exposed faces or sides that configure tracks (7) for brake pad contact; said tracks (7) are carved with a plurality of non-passing cavities (8) randomly distributed or in rows, with several of them aligned and according to a suitable spacing, however, in any distribution, said cavities provide means for temporary storage of the plasma created between the tracks (7) of the discs (4 and 5) and the surface of the brake pad at the moment of braking, allowing the entire contact area of the brake pad to rub against said tracks (7) of the brake discs. brake; between such holes (8) and in a smaller quantity, several tiny slightly curved insert clean channels are also distributed (9).

Description

Field of Invention.

Mais particularmente a presente Invenção refere-se a aprimoramentos técnicos e funcionais introduzidos em disco de freio para veiculos leves, médios e pesados em geral, sejam eles de qualquer natureza, ou seja, de turismo, de carga, esportivos e os de competições.More particularly, the present invention relates to technical and functional improvements introduced in brake discs for light, medium and heavy vehicles in general, whether of any nature, that is, tourism, cargo, sports and competitions.

State of the art.

As maiorias dos veiculos modernos possuem sistema de freios a disco, nas rodas dianteiras, podendo também ser encontrados nas rodas traseiras. Esta é a parte do sistema de freios que realmente faz o carro parar. O tipo mais comum de freio a disco nos carros modernos.Most modern vehicles have a disc brake system on the front wheels, which can also be found on the rear wheels. This is the part of the brake system that actually stops the car. The most common type of disc brake in modern cars.

O freio a disco é uma máquina de conversão de energia cinética em calor por meio da fricção. Sua eficiência é medida pela sua capacidade de dissipar o calor gerado. Um freio a disco, feito geralmente de ferro fundido é conectado à roda ou ao eixo. Para parar a roda, um material de fricção na forma de pastilhas de freio (montadas em um dispositivo chamado pinça) é forçado mecanicamente, hidraulicamente, pneumaticamente ou eletromagneticamente contra os dois lados do disco. A fricção faz com que o disco e a roda fixada a ele desacelerem ou parem.The disc brake is a machine for converting kinetic energy into heat through friction. Its efficiency is measured by its ability to dissipate generated heat. A disc brake, usually made of cast iron, is attached to the wheel or axle. To stop the wheel, a friction material in the form of brake pads (mounted in a device called a caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically against both sides of the disc. Friction causes the disc and the wheel attached to it to slow down or stop.

Portanto, um fator importante em um disco de freio é, sem dúvida alguma, os seus meios para conversão de energia cinética em calor, bem como os meios para dissipar o calor produzido.Therefore, an important factor in a brake disc is undoubtedly its means for converting kinetic energy into heat, as well as the means for dissipating the heat produced.

Atualmente existe uma infinidade de discos para tal finalidade, todos eles com as suas particularidades construtivas, tal como aqueles ensinados nos documentos: PI0904737-9 - 30/11/2009 DISCO DO FREIO INTERNAMENTE VENTILADO PARA VEÍCULOS MU8900932-0 - 06/05/2009 DISPOSIÇÃO INTRODUZIDA EM DISCO DE FREIO COM REBAIXOS RETIFICADORES DE PASTILHAS PI0800190-1 - 14/02/2008 DISCO DE FREIO, SISTEMA DE FREIOS E VEÍCULO PI0610815 - 17/05/2006 LIGAÇÃO ENTRE O DISCO DO FREIO E O CUBO PI0510787 - 11/05/2005 DISPOSIÇÃO ENTRE O CUBO E O DISCO DO FREIO, COM DISCO DO FREIO DESLOCÁVEL PI0508667 - 02/03/2005 ELEMENTOS INTERMEDIÁRIOS PARA UMA COMBINAÇÃO DE DISCO DO FREIO COM O CUBO DO DISCO DO FREIO E COMBINAÇÃO DE DISCO DO FREIO COM O CUBO DO DISCO DO FREIO PI0417702 - 17/12/2004 MÉTODO DE FABRICAÇÃO DE ELEMENTO DE FRENAGEM, COMO UM DISCO OU TAMBOR DE FREIO, E MODELO, NÚCLEO E MOLDE DE ELEMENTO DE FRENAGEM PARA VEÍCULOS CORRESPONDENTES PI0417239 - 03/12/2004 DISCO DE FREIO PI0405217 - 30/09/2004 PINÇA DE FREIO PI0413612 - 18/08/2004 FREIO A DISCO E DISCO DE FREIO PI0304857 - 07/11/2003 DISPOSITIVO DE FIXAÇÃO E USINAGEM DE DISCO DE FREIO E PROCESSO DE USINAGEM PI0302392-3 - 18/07/2003 ROTOR DE FREIO PI0300864 - 03/04/2003 RODA E PORÇÃO CIRCULAR PI0302903 - 04/02/2003 DISCO DE FREIO FUNDIDO PI0302905 - 29/01/2003 MÉTODO PARA PRODUZIR ROTOR DE FREIO E ROTOR DE FREIO PI0213034 - 01/10/2002 DISCO DE FREIO PARA UM FREIO DE DISCO.

BRAKE DISK CONSTRUCTION

Não resta a menor dúvida de que os documentos acima ensinam uma variedade considerável de discos de freio, entretanto, notou-se que os mesmos poderiam ser melhorados ainda mais a dissipação de calor, redução de falhas por excesso de temperatura no sistema de frenagem e melhorar o desempenho de frenagem.There is no doubt that the above documents teach a considerable variety of brake discs, however, it was noted that they could further improve heat dissipation, reduce overtemperature failures in the braking system and improve the braking performance.

Objectives of the Invention.

A concretização de um Disco de freio em ferro fundido cinzento, com furos não passantes para a armazenagem do. plasma criado entre a superficie do disco de freio e a superficie da pastilha de freio no momento da frenagem, deixando que toda a área de contato da pastilha de freio atrite com o disco de freio, e rasgos denominados "limpa pastilhas" que tem a função de canalizar o plasma para fora do raio do disco de freio e também retirar a superficie "envidrada" da pastilha de freio deixando-a assim em condições de uso até o seu esgotamento total.The realization of a gray cast iron brake disc, with non-through holes for the storage of the. plasma created between the surface of the brake disc and the surface of the brake pad at the moment of braking, allowing the entire contact area of the brake pad to rub against the brake disc, and tears called "clean pads" that have the function of channeling the plasma outside the radius of the brake disc and also removing the "glazed" surface of the brake pad, leaving it in use condition until its total exhaustion.

Description of drawings.

Para melhor compreensão da presente Invenção, é feita em seguida uma descrição detalhada da mesma, fazendo-se referências aos desenhos anexos: FIGURA 5 e 2 representam vistas isométricas do presente disco de freio aperfeiçoado; FIGURA 6 ilustra uma vista lateral do disco de freio; FIGURA 7 é uma vista em elevação anterior do disco de freio; e a FIGURA 8 expõe uma vista ampliada do corte indicado na figura anterior.For a better understanding of the present invention, a detailed description of the same is given below, with reference to the accompanying drawings: FIGURE 5 and 2 represent isometric views of the present improved brake disc; FIGURE 6 illustrates a side view of the brake disc; FIGURE 7 is a front elevation view of the brake disc; and FIGURE 8 shows an enlarged view of the section indicated in the previous figure.

Detailed description of the invention.

De acordo com estas ilustrações e em seus pormenores, a presente Invenção, APERFEIÇOAMENTO EM DISCO DE FREIO AUTOMOTIVO, é tradicionalmente do tipo fabricado em peça única de ferro fundido cinzento e suas ligas, tendo várias partes usuais, em que a primeira é um cubo cilindrico (1), distanciador, tendo uma extremidade flangeada em perfil peculiar (2) , ordinariamente dentado, onde cada dente é vazado por furo (3) de fixação do conjunto no local de uso, enquanto pela extremidade oposta dito cubo cilindrico (1) está integrado com um par de discos, um no lado interno (4) e outro no lado externo (5) , adequadamente espaçados por aletas radiais de ventilação (6), que se desenvolvem com uma determinada geometria suficiente para funcionarem como um rotor de palhetas para estabelecer um fluxo de ar que constitui o primeiro recurso de ventilação para resfriamento dos discos (4- 5), cujas faces ou lados expostos configura verdadeiras pistas (7) para contato das pastilhas de frenagem (não ilustradas).According to these illustrations and in their details, the present invention, IMPROVEMENT IN AUTOMOTIVE BRAKE DISC, is traditionally of the type manufactured in a single piece of gray cast iron and its alloys, having several usual parts, the first being a cylindrical cube (1), spacer, having a flanged end in a peculiar profile (2), ordinarily toothed, where each tooth is cast through a hole (3) for fixing the assembly at the place of use, while at the opposite end said cylindrical hub (1) is integrated with a pair of discs, one on the inner side (4) and the other on the outer side (5), suitably spaced by radial ventilation fins (6), which develop with a given geometry sufficient to function as a vane rotor for establish an air flow that constitutes the first ventilation resource for cooling the discs (4-5), whose exposed faces or sides configure true tracks (7) for contacting the brake pads (does not illustrate of).

A presente invenção está caracterizada pelo fato de as pistas (7) serem lavradas com pluralidade de cavidades não passantes (8) distribuídos aleatoriamente ou em carreiras com vários deles alinhados e de acordo com um espaçamento adequado, porém, em qualquer distribuição, ditas cavidades conferem meios para o armazenagem temporária do plasma criado entre as pistas (7) dos discos (4 e 5) e a superfície da pastilha de freio no momento da frenagem, deixando que toda a área de contato da pastilha de freio atrite com as referidas pistas (7) dos discos de freio.The present invention is characterized by the fact that the tracks (7) are carved with a plurality of non-passing cavities (8) randomly distributed or in rows with several of them aligned and according to an adequate spacing, however, in any distribution, said cavities confer means for the temporary storage of the plasma created between the tracks (7) of the discs (4 and 5) and the surface of the brake pad at the moment of braking, allowing the entire contact area of the brake pad to rub against said tracks ( 7) of the brake discs.

Entre tais furos (8) e em quantidade menor, são distribuídos também vários minúsculos canais limpa pastilhas ligeiramente arqueados (9), que nascem bem próximo do diâmetro interno dos referidos discos (4 e 5) e terminam no diâmetro externo dos mesmos. Assim, ditos canais "limpa pastilhas" têm a função de canalizar o plasma para fora do raio do disco de freio e também retirar a superfície "vidrada" da pastilha de freio deixando-a assim em condições de uso até o esgotamento total dela.Between such holes (8) and in a smaller quantity, several tiny channels clean slightly arcuate pads (9) are also distributed, which start very close to the inner diameter of said discs (4 and 5) and end in the outer diameter of the same. Thus, said channels "clean pads" have the function of channeling the plasma out of the radius of the brake disc and also removing the "glazed" surface of the brake pad, thus leaving it in use conditions until its total exhaustion.

As cavidades (8) são preferivelmente circulares e de pouca profundidade, como também não apresentam cantos vivos internamente. As cavidades (8) são distribuídas aleatoriamente ou formando carreiras inclinadas e espaçadas equidistantemente. Os canais (9) apresentam seção transversal em "U" .The cavities (8) are preferably circular and of little depth, as well as not having sharp corners internally. The cavities (8) are randomly distributed or forming slanted rows and equidistantly spaced. The channels (9) have a "U" cross section.

Será compreendido que determinadas características e combinações das cavidades e canais em relação ás pistas de frenagem poderão variar consideravelmente mantendo-se o mesmo conceito funcional para o conjunto, consequentemente, nota-se que a construção ora descrita em detalhes à titulo de exemplo está claramente sujeita a variações construtivas, porém, sempre dentro do escopo do conceito inventivo ora revelado de se prever cavidades retentoras do plasma criado durante a frenagem e de canais limpa pastilhas, e como muitas modificações podem ser feitas na configuração ora detalhada de acordo com as exigências descritivas da lei, é entendido que os detalhes presentes devam ser interpretados como de forma ilustrativa e não limitadora.It will be understood that certain characteristics and combinations of cavities and channels in relation to the brake tracks may vary considerably while maintaining the same functional concept for the set, consequently, it is noted that the construction described in detail by way of example is clearly subject to to constructive variations, however, always within the scope of the inventive concept now revealed to provide retaining cavities of the plasma created during braking and clean pads channels, and how many modifications can be made to the configuration now detailed in accordance with the descriptive requirements of the By law, it is understood that the present details are to be interpreted as illustrative and not limiting.
