Abstract

LA INVENCION SE REFIERE A UN SISTEMA DE CONTROL DE DIRECCION PARA UN VEHICULO ORUGA QUE COMPRENDE UN ELEMENTO DE DIRECCION (66) QUE DEBE SER MANEJADO POR UN OPERARIO, UNA CAJA DE CAMBIOS (16) QUE ES ACCIONADA A TRAVES DE UN EMBRAGUE (18) POR UN MOTOR (10), UNA PALANCA DE EMBRAGUE (70) QUE PUEDE DESPLAZARSE ENTRE UNA POSICION DE ESTACIONAMIENTO, UNA POSICION NEUTRAL Y UNA POSICION DE ENGRANE DE MARCHA, UNA UNIDAD DE CONTROL (64) PARA GENERAR UNA SEÑAL DE CONTROL DE DIRECCION EN FUNCION DE UNA POSICION DEL ELEMENTO DE DIRECCION (66), Y CAMINOS DE RODADURA DERECHO E IZQUIERDO DE LA ORUGA QUE SON ACCIONADOS POR UN MECANISMO DE IMPULSION DIFERENCIAL (24, 28) EN FUNCION DE UNA SEÑAL DE CONTROL. PARA PODER ACTIVAR LA DIRECCION INDEPENDIENTEMENTE DE LA POSICION DEL VOLANTE DURANTE UN MOVIMIENTO DE LA PALANCA DE EMBRAGUE Y PASAR DESDE SU POSICION DE ESTACIONAMIENTO A SU POSICION NEUTRAL O DESDE SU POSICION DE ESTACIONAMIENTO A SU POSICION DE ENGRANE DE MARCHA, EL SISTEMA DE DIRECCION COMPRENDE UN SENSOR DE EMBRAGUE (73A) QUE GENERA UNA SEÑAL DE DESEMBRAGUE CUANDO EL EMBRAGUE ESTA DESEMBRAGADO, UN SENSOR DE PALANCA DE EMBRAGUE (71) QUE GENERA UNA SEÑAL DE PALANCA DE EMBRAGUE QUE REPRESENTA LA POSICION DE LA PALANCA DE EMBRAGUE, UN SENSOR DE POSICION DE GIRO (68) CONECTADO AL ELEMENTO DE DIRECCION (66) QUE GENERA UNA SEÑAL DE DIRECCION QUE REPRESENTA LA POSICION DEL ELEMENTO DE DIRECCION (66), ASI COMO UNA UNIDAD DE CONTROL. ESTA UNIDAD DE CONTROL CONTIENE MEDIOS PARA GENERAR UNA SEÑAL DE CONTROL DE DIRECCION QUE DEPENDE DE LA SEÑAL DE DESEMBRAGUE, LA SEÑAL DE PALANCA DE EMBRAGUE Y LA SEÑAL DE DIRECCION. LA UNIDAD DE CONTROL CONTIENE, ADEMAS, MEDIOS PARA DESACTIVAR EL VIRAJE DEL VEHICULO CUANDO LA PALANCA DE EMBRAGUE (70) ESTA DESPLAZADA FUERA DE SU POSICION DE ESTACIONAMIENTO Y DURANTE EL TIEMPO QUE EL EMBRAGUE (18) ESTA DESEMBRAGADO Y EL ELEMENTO DE DIRECCION (66) SE ENCUENTRA EN UNA PRIMERA POSICION NO CENTRADA Y DESVIADA.
