A modular camshaft 1 comprises at least two modular elements or modules (2) removably coupled together; each module (2) carries at least one cam and comprises two cylindrical elements (6, 7) disposed on the same axis and projecting in opposite directions from opposing faces (4, 5) of said cam (3), a first cylindrical element (6) acting as a hub and the second (7) being hollow and acting as a seat, the seat (7) of one modular element (2) being arranged to receive the hub (6) of the other module (2) so as to define the camshaft (1), on each hub (7) there being provided means (9) which cooperate with counter-means provided in each seat (7) to torsionally lock said two modular elements (2) together. According to the invention the camshaft (1) comprises, between two consecutive cams (3), at least one annular element (10) spaced from said cams (3) and removably mounted on one of the two cylindrical elements (6, 7) of each module (2), said annular element (10) comprising in its outer edge (11) at least one recess (12) so as to act as an additional cam, and comprising in its inner edge (13) means (14) for torsionally locking it to the cylindrical element (6, 7) on which said element or removable cam (10) is mounted. <IMAGE> |
