Abstract

Problema Proporcionar un dispositivo sellador montado en un dispositivo de cojinete de vehículo, provisto de una estructura capaz de liberar presión y por lo tanto evitar que la presión interna aumente, en el caso en que la presión interna del dispositivo de cojinete aumente en un dispositivo sellador que tenga una arista selladora proporcionada hacia la parte interna del dispositivo de cojinete. Medio de resolución Proporcionar una saliente para formar un espacio de una parte de una circunferencia entre la arista de sellado y un miembro deslizante de emparejamiento para ajustar la presión interna del dispositivo de cojinete, provisto dentro del alcance de una parte deslizante de la arista de sellado y en una parte de la circunferencia de la parte deslizante, en un dispositivo sellador que tenga una arista de sellado proporcionada hacia la parte interna del dispositivo de cojinete. La saliente se proporciona como una saliente posicionada en la parte del extremo de la punta de la arista de sellado, una saliente con forma de nervadura que se extiende en una dirección axial, y una saliente con un tamaño que se desgasta al transcurrir un tiempo de funcionamiento predeterminado. Dibujo seleccionado Figura 2.
