Abstract

CON UN DISPOSITIVO PARA LA TENSION HIDRAULICA Y EL AJUSTE DE LA TRANSMISION POR CADENA DE ARBOLES DE LEVAS SE DESPLAZA LA CADENA (4), QUE CIRCUNDA AMBOS ARBOLES DE LEVAS, JUNTAMENTE CON SU DISPOSITIVO TENSOR (7), EN LA DIRECCION TRANSVERSAL DE LA CADENA (4). CON ELLO, SE ALARGA EL TRAMO DE CARGA (6) DE LA CADENA Y SE ACORTA EL TRAMO LIBRE (5) O VICEVERSA. COMO LIQUIDO HIDRAULICO SE EMPLEA ACEITE DE MOTOR, CUYA PRESION SE INCREMENTA CON LAS ROTACIONES DEL MOTOR, BIEN DIRECTAMENTE O BIEN MEDIANTE UN DISTRIBUIDOR HIDRAULICO PARA AJUSTAR EL DISPOSITIVO TENSOR (7).
