Abstract

Se proporciona un conjunto de dirección asistida mejorado. El conjunto de dirección asistida incluye un mecanismo de fin de carrera y un cartucho de válvula que es accionado por los anillos actuadores izquierdo y derecho del mecanismo de fin de carrera, los anillos actuadores se extienden parcialmente alrededor de un eje de salida. Los anillos actuadores pueden ajustarse individualmente para el alivio de fin de carrera deseado para limitar la presión máxima del sistema cuando el conjunto de dirección se acerca al ajuste de tope del eje deseado. El cartucho de la válvula proporciona una función de fin de carrera y una función de alivio de presión y está en comunicación fluida con las cámaras de presión izquierda y derecha para recircular el fluido hidráulico en caso de una condición de apagado.
