Hub de rodamiento, cómo reemplazar el centro de rodamientos en Daewoo Nexia, hágalo usted mismo

Al conducir en un automóvil, a menudo es posible observar la ocurrencia del zumbido característico, que puede verlo con el tiempo. Además, cambia dependiendo del estado de la superficie de la carretera. En un buen camino, el zumbido desaparece o disminuye, por lo que puede parecer que no hay necesidad de reparar, pero tan pronto como las ruedas van a un mal camino, el zum aparece de nuevo. Además, a alta velocidad, puede escuchar un relieve específico. La razón de la aparición de estos síntomas, por regla general, es la culpa del cojinete del cubo. Vale la pena señalar que si no reemplaza un rodamiento de zumbidos de manera oportuna, entonces cuando la conduce puede atascarse, lo que es extremadamente peligroso y representa una amenaza para la vida, por lo tanto, con las más mínimas manifestaciones de los síntomas de mal funcionamiento descritos anteriormente, Debe ser reemplazado por el cojinete del hub lo antes posible. Sobre esto más allá en el artículo.

Hub de rodamiento, qué tareas que realiza.

El rodamiento es un mecanismo que soporta parte del soporte. Es capaz de mantener el eje, el eje o cualquier otro elemento, pero en cualquier caso, su propósito principal es la fijación del eje en el espacio, lo que garantiza su distribución o rotación libre. La segunda función del cojinete del cubo es la percepción de la carga mecánica, así como su transferencia a otros elementos.

El cojinete del hub es un mecanismo que es un rodamiento. Proporciona una rotación suave de la rueda alrededor del eje. Estos rodamientos son de una sola fila y doble fila, así como de tipo abierto y cerrado. Se utilizan en pasajeros y camiones. Los cojinetes de las ruedas para las ruedas delanteras y traseras difieren significativamente entre sí.

Los cojinetes del cubo de coches están constantemente sometidos a cargas extremas. Incluye diferencias de alta temperatura, impacto ambiental, la formación de cargas de choque al ingresar a los pozos, la dirección, los frenos, la unidad. Vale la pena señalar que la contrasa no debe evitar la rotación de la rueda, que debe girar con una fricción mínima y un ruido permitido.
