Abstract

a presente invenção refere-se a uma aba (100) para frenagem de um veículo pelo controle da pressão de um fluxo (105) de gás de exaustão de um motor de combustão (300) compreendendo: uma primeira porção de braço (110); uma segunda porção de braço (120) e uma porção de suporte (130). a porção de suporte (130) está disposta entre a primeira porção de braço (110) e a segunda porção de braço (120). a porção de suporte (130) está configurada para montar a aba (100) rotativa em torno de um eixo de rotação (135) tangencial em uma vista seccional transversal do fluxo (105) de gás de exaustão. a primeira porção de braço (110) e a segunda porção de braço (120) compreendem uma geometria para equilibrar uma pressão que atua sobre a primeira porção de braço (110) com a pressão atuando sobre a segunda porção de braço (120) para limitar um torque máximo atuando sobre a aba (100) em torno do eixo rotacional (135).
