Abstract

EL MOTOR DE COMBUSTION INTERNA TIENE UNA TRANSMISION DEL ARBOL DE LEVAS, EN DONDE LA SALIDA DEL ARBOL DE LEVAS (2) PROPULSADA POR EL EJE DEL CIGUEÑAL (1), PROPULSA LA ENTRADA DEL ARBOL DE LEVAS (3) CON UNA CADENA (4). PARA TENSAR LA CADENA (4) SE PRESIONAN CONTRA SI DOS EMBOLOS HIDRAULICOS (8, 9) CONTRA EL LOSTRUM (6) Y LASTTRUM (5) DE LOS LADOS INTERIORES DE LAS CADENAS. PARA AJUSTAR EL GIRO RELATIVO DEL ARBOL DE LEVAS SE EMPUJA UNA ESTRUCTURA DE EMBOLOS HIDRAULICOS (8, 9) Y UNA CADENA (4) TRANSVERSALMENTE AL ARBOL DE LEVAS (2, 3), DE TAL FORMA QUE SE ACORTA EL LOSTTRUM (6) Y EL LASTTRUM (5) SE ALARGA O AL REVES.
