Abstract

Un muelle neumático con características de amortiguación para un conjunto de suspensión de un vehículo de uso pesado incluye una cámara de fuelle, una cámara del pistón y un orificio asimétrico. El orificio asimétrico está en comunicación fluida con la cámara de fuelle y la cámara del pistón del muelle neumático. El orificio asimétrico provee características de amortiguación asimétricas al muelle neumático del vehículo de uso pesado.
