Abstract

Se proporciona un ensamble de defensa/silenciador para realizar simultáneamente funciones de atenuacion de ruido y proteccion contra impactos para un vehículo automotor. El ensamble de defensa/silenciador se forma al menos en parte a partir de láminas estampadas del material. Las láminas incluyen una placa interna formada con canales de entrada y salida. Las placas de tubos de entrada y salida se fijan sobre partes de la placa interna adyacente a los canales de entrada y salida para definir tubos de entrada y salida. Un revestimiento externo frontal se coloca en la cercanía del extremo posterior del vehículo y se configura para que este espaciado a partir de partes de la placa interna para definir una cámara frontal. Un revestimiento externo posterior se encuentra también espaciado de la placa interna para definir una cámara posterior. Un material plástico puede estar encajado sobre el revestimiento externo posterior por razon de atraccion estética del ensamble.
