Abstract
Tambor expandible de construcción de neumáticos perfeccionado para la conformación tórica de armazón de neumáticos confeccionados en forma de manguito cilíndrico, dicho manguito cilíndrico presentando en las extremidades rehinchamientos anulares circunferencialmente inextensibles desarrollados radialmente hacia el interior, usualmente conocidos como talones del armazón, definiéndose al tara del talón la mitad de la diferencia entre el diámetro interno de dicho manguito y el diámetro interno de dicho talón, dicho tambor comprendiendo dos discos coaxiales, sustancialmente constituídos por un cubo y por una brida anular a este solidaria, axialmente recíprocamente desplazables, solidarios entre si a la rotación, soportados por un eje rodante que sobresale a un lado del relativo dispositivo de accionamiento, dichos discos presentando la superficie radialmente externa comprendiendo una primera parte apta de recibir dichos talones del manguito, y ni más ni menos definida asiento de talón, un resalte anular coaxial, de diámetro externo mayor que aquel de dicho asiento de talón, dispuesto al lado de dicho asiento por la parte axialmente interna respecto a dicho tambor, dicho tambor estando caracterizado por el hecho que en dichos discos la superficie radialmente externa comprende una segunda parte de forma troncocónica convergente axialmente al exterior del tambor, uniéndose a lo largo de su borde axialmente interno con el borde axialmente externo de dicho asiento de talón, dicho resalte anular sobresale hacia un lado de dicho disco, axialmente hacia el interior del tambor, el plano normal al eje de éste y tangente al borde axialmente interno de dicho resalte anular resultando axialmente más interno que el plano normal al eje del tambor y tangente a la superficie axialmente interna de dicha arandela anular.
