Abstract

Se describe un tensor que logra amortiguacion asimétrica mediante una placa movil de rampas. La placa movil de rampas (3) está en contacto friccionante con el brazo (1) y provee amortiguacion de friccion asimétrica para el brazo tensor (1) cuando el brazo sufre enrollamiento y comienza a alejarse de la correa. La placa de rampas (3) está asociada giratoriamente con el desplazamiento del brazo tensor (1) a través de un resorte (2). El brazo tensor (1) puede pivotar en dos direcciones. A medida que el brazo tensor (1) pivota en direccion hacia la correa, la placa de rampas (3) es impulsada de manera de minimizar la friccion entre la placa de rampas (3) y el tensor. Cuando el brazo tensor (1) pivota en la direccion opuesta, como tipificado potencialmente por enrollamiento, la placa de rampas (3) es impulsada de manera de incrementar la friccion entre la placa de rampas (3) y el tensor, minimizando en consecuencia el enrollamiento del brazo tensor (1).
