Abstract
SE DESCRIBE UN SISTEMA DE MANDO DE LA DIRECCION PARA UN VEHICULO DE ORUGAS. EL VEHICULO DE ORUGAS LLEVA UN MOTOR DE TRACCION (10) QUE MUEVE UNA ORUGA IZQUIERDA Y UNA ORUGA DERECHA POR MEDIO DE UN MECANISMO DE ACCIONAMIENTO DIFERENCIAL (24, 28), ACTUANDO SOBRE EL MECANISMO DE ACCIONAMIENTO (24, 28) POR LO MENOS UN MOTOR DE DIRECCION (42), MEDIANTE EL CUAL Y EN FUNCION DE LAS REVOLUCIONES DEL MOTOR DE DIRECCION SE PUEDE AJUSTAR UNA VELOCIDAD RELATIVA ENTRE LA ORUGA IZQUIERDA Y LA ORUGA DERECHA. EL SISTEMA DE MANDO DE LA DIRECCION CONTIENE UN SENSOR DE VELOCIDAD DEL VEHICULO (76), UN SENSOR DE LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION (80), UN DISPOSITIVO DE ESPECIFICACION DE DIRECCION (64) QUE PUEDE AJUSTAR UN OPERARIO, Y UNA UNIDAD DE MANDO (62) PARA EL MANDO DE LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION EN FUNCION DEL AJUSTE DEL DISPOSITIVO DE MANDO DE LA DIRECCION (64). PARA PODER APROVECHAR LAS VENTAJAS DE UN DISPOSITIVO DE MANDO DE LA DIRECCION CENTRADO POR MUELLE, Y EVITAR QUE SE PRODUZCA UN GIRO AUTOPERPETUANTE DEL VEHICULO, SE PROPONE QUE EL DISPOSITIVO DE MANDO DE LA DIRECCION SEA UN DISPOSITIVO DE MANDO DE DIRECCION (54) NO CENTRADO, Y QUE LA UNIDAD DE MANDO (62) EVALUE LAS SEÑALES DE LOS SENSORES DE TAL MANERA QUE IMPIDA UN AUMENTO DE LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION CUANDO EL COCIENTE ENTRE LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION Y LA VELOCIDAD DEL VEHICULO SEA SUPERIOR A UN DETERMINADO VALOR UMBRAL. EN PARTICULAR SE DEBERA REDUCIR LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION CUANDO LA CAJA DE TRANSMISION SITUADA EN LA CADENA CINEMATICA SE ENCUENTRE EN PUNTO MUERTO O CUANDO NO ESTE ACOPLADO UN EMBRAGUE, CUANDO EL COCIENTE ENTRE LAS REVOLUCIONES DEL MOTOR DE LA DIRECCION Y LA VELOCIDAD DEL VEHICULO SEA SUPERIOR A UN DETERMINADO VALOR UMBRAL Y CUANDO LA VELOCIDAD DEL VEHICULO SEA INFERIOR A UN DETERMINADO VALOR DE REFERENCIA.
