Abstract:
A chain-tensioning rod, for an internal combustion engine with an overhead camshaft valvetrain to keep in tension a timing chain, includes a shoe, which is pressed against the timing chain, and a supporting arm of the shoe, allows a simple assembly of the arm and of the relative shoe because the shoe is formed by a monolithic piece having, on one side thereof, a sliding surface and on, the opposite side, a supporting surface and a contact element connected to the supporting surface by a longitudinal central rib; and the supporting arm is formed by an elongated sheet having a longitudinal pass-through slit extending from a distal end thereof, wherein it is open, so that insertion of the supporting arm on the supporting surface takes place by making said rib to slide in the slit, the rib operating as transversal locking device of the supporting arm on the supporting surface.
