Abstract

UNA DIRECCION DE VEHICULO PARA FIRAR LAS RUEDAS ORIENTABLES DE UN VEHICULO QUE TIENE UN MOTOR DE FLUIDO CON UN ALOJAMIENTO QUE DEFINE UNA CAMARA DE FLUIDO Y UN PISTON EN LA CAMARA QUE DIVIDE LA CAMARA EN DOS PARTES PRIMERA Y SEGUNDA. UN MIEMBRO DE ENTRADA DE DIRECCION GIRABLE ES SOPORTADO POR EL ALOJAMIENTO. UN ELEMENTO COMPLEMENTARIO GIRABLE ES ASOCIADO CON EL PISTON Y GIRABLE EN MOVIMIENTO DEL PISTON EN LA CAMARA. UNA VALVULA CONTRA EL FLUJO DEL FLUIDO PRESURIZADO A LA PRIMERA Y SEGUNDA PARTES DE LA CAMARA. LA VALVULA COMPRENDE RELATIVAMENTE. UNA DE LAS PARTES DE LA VALVULA ESTA CONECTADA CON EL ELEMENTO DE ENTRADA Y LA OTRA PARTE DE LA VALVULA ESTA CONECTADA CON EL ELEMENTO COMPLEMENTARIO QUE FORMA UNA UNIDAD CON ELLO. LA UNIDAD TIENE UNA SUPERFICIE CONTRA LA CUAL LA PRESION DEL FLUIDO EN LA PRIMERA Y SEGUNDA PARTE DE LA CAMARA ACTIVA TENDIENDO A CREAR UNA FUERZA AXIAL EN LA UNIDAD. LA PRESION ES APLICADA A OTRA AREA DE SUPERFICIE DE LA UNIDAD PARA EQUILIBRAR UNA FUERZA AXIAL QUE ACTUAEN LA UNIDAD.
