Abstract

Un vehículo con orugas tiene un sistema electrohidráulico de accionamiento/direccion que tiene una bomba de direccion hidráulica de desplazamiento variable accionada por motor que impulsa un motor de direccion hidráulica que está acoplado a un mecanismo diferencial accionador de orugas por medio de una transmision con relaciones de cambio multiples. Un volante está acoplado a un dispositivo de friccion variable que produce una fuerza de friccion variable que resiste la rotacion del volante. Un sistema de control responde a una posicion del volante y controla el desplazamiento de la bomba de direccion y controla el dispositivo de friccion. El sistema de control pone al dispositivo de friccion variable en su nivel alto de friccion, cuando se llega a un límite del desplazamiento de la bomba en direccion cuando la transmision está en una de sus relaciones de cambio más altas.
