Abstract

La invención se refiere a un árbol de levas que comprende un árbol de soporte (3) configurado como árbol hueco. Un árbol interior (5) está dispuesto concéntricamente con respecto al interior del árbol de soporte, pudiendo girar dicho árbol interior (5) con respecto al árbol de soporte (3) Un primer segmento de leva (7) está dispuesto sobre el árbol de soporte (3), presentando dicho segmento de leva un primer rebaje (9) para alojar el árbol de soporte (3) pudiendo girar con respecto al árbol de soporte (3) y estando unido de manera resistente al giro con el árbol interior (5) a través de una primera abertura (11) en el árbol de soporte (3) . El primer segmento de leva (7) comprende al menos dos contornos de leva (13, 15). Además la unión entre el árbol interior (5) y el primer segmento de leva (7) está configurada de tal manera que el primer segmento de leva (7) puede desplazarse axialmente con respecto al árbol interior (5) y al árbol de soporte (3).
