Abstract

UNA DIRECCION DE VEHICULO PARA TORCER LAS RUEDAS GIRABLES DE UN VEHICULO QUE TIENE UNA MOTOR FLUIDO CON UN ALOJAMIENTO (11) DEFINIENDO LA CAMARA FLUIDA (13) Y UN PISTON (14) EN LA CAMARA QUE DIVIDE LA CAMARA EN UNA PRIMERA PARTE (16) Y EN UNA SEGUNDA PARTE (18). UN MIEMBRO (33) DE ENTRADA GIRABLE ROTATIVAMENTE SE SOPORTA MEDIANTE EL ALOJAMIENTO. UN MIEMBRO DE SEGUIMIENTO (100) ROTATIVO SE ASOCIA CON EL PISTON Y ROTA SOBRE EL MOVIMIENTO DEL PISTON EN LA CAMARA. UNA VALVULA CONTROLA EL FLUJO DE FLUIDO PRESURIZADO HACIA LA PRIMERA Y SEGUNDA PARTES DE LA CAMARA. LA VALVULA CONSTA DE UNA PRIMERA (40) Y UNA SEGUNDA (41) PARTE DE VALVULA MOVIBLE RELATIVAMENTE. UNA DE LAS PARTES DE LA VALVULA SE CONECTA CON EL MIEMBRO DE ENTRADA Y LA OTRA DE LA PARTES DE LA VALVULA SE CONECTA CON EL MIEMBRO DE SEGUIMIENTO FORMANDO UNA UNIDAD (116) CON EL MISMO. LA UNIDAD TIENE UNA SUPERFICIE (129, 134) CONTRA CUYA PRESION DE FLUIDO EN LA PRIMERA Y EN LA SEGUNDA PARTES DE LA CAMARA ACTUA TENDIENDO A CREAR UNA FUERZAAXIAL SOBRE LA UNIDAD. SE APLICA PRESION A OTRA AREA DE SUPERFICIE (136) DE LA UNIDAD PARA BALANCEAR LA FUERZA AXIAL ACTUANDO SOBRE LA UNIDAD.
