Abstract

Atuador hidráulico para um servo de uma mudança de engrenagem, e correspondente método de fabricação, onde, aqui é descrito, um atuador hidráulico (5) para um servo- mecanismo de uma caixa-de-mudança de engrenagem provida de um eixo (2) de controle; o atuador hidráulico (5) desloca o eixo (2) de controle axialmente ao longo de um seu eixo (3) central, é ajustado em uma posição correspondendo a uma porção intermediária do eixo (2) de controle, e tem duas câmaras (7), as quais são alternadamente preenchidas com um fluido pressurizado, são atravessadas pelo eixo (2) de controle, e são separadas uma da outra por uma flange (8), a qual é fixada sobre o eixo (2) de controle e define um pistão do atuador hidráulico (5); o eixo (2) de controle tem ao menos uma fileira de assentos (11), a qual é uniformemente distribuída ao longo de uma circunferência e ao redor do eixo central (3) do eixo (2) de controle; e a flange (8) tem ao menos uma aba lateral (12), a qual é ajustada acima da fileira de assentos (11) e é deformada em uma posição correspondendo a cada assento (11) para engastar o assento (11) - (fig. 1).
