Abstract

Un miembro de émbolo 3 usado para una transmisión tipo correa continuamente variable se configura mediante el moldeo a presión en frío de un material en bruto 32 de conformidad con el moldeo por embutición profunda, y el forjado cerrado, el moldeo por compresión o un moldeo combinado del mismo, donde durante el moldeo a presión en frío, se configura un grosor de una porción de esquina doblada 3f, que al menos hace que una porción de manguito 3c y una porción formada tipo escalón (porción de asiento de resorte) 3d sean continuas entre sí para incrementarse en 30 % o más con relación a un grosor del material en bruto 32, y luego una capa superficial endurecida 3B se configura para formarse en ambos de los lados frontal y posterior completos del miembro de émbolo mediante la realización de un tratamiento de nitruración blanda.
