Abstract

Un ensamble de soporte lateral, de contacto constante, para un carro de ferrocarril, incluye un alojamiento que tiene una base, un par de aberturas de montaje formadas a través del espesor de la base; una pared de alojamiento generalmente cilíndrica, que se extiende hacia arriba sobre la base; un par de canales diametralmente opuestos; un par de aberturas diametralmente opuestas y un miembro de guía dispuesto centralmente en y que se extiende hacia arriba desde una superficie interna de la base. Está dispuesta una tapa para su movimiento recíproco axial con relación al alojamiento. Está dispuesto un resorte elastomérico dentro de una cámara generalmente cerrada, formada por una combinación del alojamiento y la tapa. Está provisto un par de pasajes de aire para disipar el calor generado durante la operación del ensamble de soporte lateral de contacto constante. Cada pasaje de aire está definido por un par de aberturas alineadas, formadas a través de una porción de pared de la tapa. Cada abertura puede estar dispuesta dentro de un receptáculo provisto dentro de la pared de la tapa.
