Abstract

VEHICULO PARA MANIPULACION DE CARGAS QUE TIENE DOS PARES DE RUEDAS MOVILES PARA SU DIRECCION, YENDO MONTADO CADA PAR DE RUEDAS EN LADOS OPUESTOS DEL CHASIS DEL VEHICULO Y PUDIENDO BLOQUEARSE AL MENOS UN PAR PARA QUE LA DIRECCION SE EFECTUE UNICAMENTE A TRAVES DEL OTRO PAR DE RUEDAS. UN SENSOR VA ASOCIADO A CADA PAR DE RUEDAS Y GENERA UNA SEÑAL ELECTRICA PARA UN DISPOSITIVO DE CONTROL CUANDO LOS EJES DE ROTACION DE LAS RUEDAS RESPECTIVAS SON PERPENDICULARES AL EJE LONGITUDINAL DEL VEHICULO. EL DISPOSITIVO DE CONTROL INCLUYE UN SELECTOR QUE CONSTA DE UN CONMUTADOR ELECTRICO PARA QUE UN OPERADOR SELECCIONE EL MODO SENCILLO DE DIRECCION, EN EL QUE SOLAMENTE UNO DE LOS PARES DE RUEDAS SON MOVILES, O UN MODO DE DIRECCION COMPUESTO, EN EL QUE AMBOS PARES DE RUEDAS PUEDEN MOVERSE. EL DISPOSITIVO DE CONTROL CONSTA ADEMAS DE UN ELEMENTO PARA MANTENER EL MODO SELECCIONADO HASTA QUE SE ELIGE OTRO A TRAVES DEL SELECTOR Y RECIBE UNA SEÑAL DE AL MENOS UNO DE LOS SENSORES ASOCIADOS CON CADA PAR DE RUEDAS.
