Cubo de rolamento, como substituir o hub do rolamento na Daewoo Nexia faz você mesmo

Ao dirigir em um carro, é muitas vezes possível observar a ocorrência do zumbido característico, que pode ressurgir ao longo do tempo. Além disso, muda dependendo do estado da superfície da estrada. Em uma boa estrada - o Hum desaparece ou diminui, por isso pode parecer que não há necessidade de reparar, mas assim que as rodas vão para uma estrada ruim - o zumbido aparece novamente. Além disso, em alta velocidade, você pode ouvir um específico em relevo. A razão para a aparência desses sintomas, por via de regra, é culpa do rolamento do cubo. Vale a pena notar que, se você não substituir um rumo de zumbido em tempo hábil, então, ao dirigir, ele pode atolar, o que é extremamente perigoso e representa uma ameaça à vida, portanto, com as menores manifestações dos sintomas de mau funcionamento acima descritos, Deve ser substituído pelo rolamento do cubo o mais rápido possível. Sobre isso ainda no artigo.

Cubo de rolamento, quais tarefas realiza

O rolamento é um mecanismo que suporta parte do suporte. É capaz de manter o eixo, eixo ou qualquer outro elemento, mas em qualquer caso, seu objetivo principal é a fixação do eixo no espaço, o que garante sua distribuição ou rotação gratuita. A segunda função do rolamento do cubo é a percepção da carga mecânica, bem como sua transferência para outros elementos.

O rolamento do cubo é um mecanismo que é um rolamento de rolamento. Ele fornece rotação suave da roda em torno do eixo. Esses rolamentos são linha única e linha dupla, bem como tipo aberto e fechado. Eles são usados \u200b\u200bem passageiros e caminhões. Os rolamentos das rodas para as rodas dianteiras e traseiras diferem significativamente um do outro.

Os rolamentos do cubo do carro são constantemente submetidos a cargas extremas. Inclui diferenças de alta temperatura, impacto ambiental, a formação de cargas de choque ao entrar nos poços, direção, freios, unidade. Vale a pena notar que a reação não deve impedir a rotação da roda, que deve girar com fricção mínima e ruído permitido.

Os rolamentos de rolos são muito suscetíveis à instalação, que, se for realizado incorretamente, é capaz de remover instantaneamente a peça em ordem. Newbies que não sabem sobre essa característica dos rolamentos de roda de rolos, muitas vezes enganam trabalhadores inescrupulosos do STO, que produzem a substituição desse elemento à mão de ambulância e mal.

Rolamento diagonal, dispositivo, vantagens e desvantagens

Os rolamentos diagonais são capazes de suportar cargas pesadas e têm excelente resistência ao desgaste.

No entanto, seu trabalho, como rolamentos de rolos, depende da instalação correta (forte aperto), caso contrário, eles falharão.

O momento do aperto do rolamento, o que é e como um torque do rolamento afeta a duração da operação

O momento do aperto do rolamento é um evento que deve ser feito com precisão de acordo com as recomendações do fabricante do veículo. Como já mencionado, a configuração incorreta do rolamento implica sua avaria.

Se anteriormente para ajustar o rolamento exigia habilidades especiais, bem como a presença de ferramentas especiais que eram difíceis de encontrar naquela época, hoje não há problemas a esse respeito. Agora, todo dono do carro pode comprar o kit de ferramentas necessário e obter dados que permite controlar independentemente o estado de rolamentos e outros elementos do carro.

O rolamento do cubo é defeituoso, sinais de quebra

Os principais sinais do mau funcionamento do rolamento do cubo do carro são:

  1. Zuminoso forte ou ruído que é ouvido por trás do veículo. Se o hub de rolamento estiver com defeito, o ruído se torna mais quando giram turnos.
  2. A aparência da reação na roda traseira, que é acompanhada por ruído ou tocando.

Ferramentas e luminárias para substituir o rolamento do cubo, segurança

  1. Puxador especial.
  2. Martelo.
  3. Tenazes para desmantelar um anéis de parada.
  4. Chave às 17.
  5. Um hexágono chave em 10.
  6. Chave de fenda.
  7. Formão.

Antes da substituição, não se esqueça de colocar as barras anti-tártaras sob as rodas traseiras e sob o corpo - foco.
