A tensioner (10) features a backstop device (40) which allows free rotation of the pivot arm (20) in one direction but not the other. Reverse rotation is prevented by friction that is able to resist torque on the pivot arm (20) under ordinary operating conditions which otherwise could permit belt tooth- skip to occur. In disclosed embodiments, the backstop device (40) includes a stop sleeve (50) and a clamp holder (60) which are axially interlocked and are able to rotate relative to each other. A clutch spring (80) surrounds permits relative rotation between the stop sleeve (50) and the clamp holder (60) in one direction but not the other. A clamp (70) retained within the clamp holder (60) frictionally engages the pivot shaft. A viscous coupling may be used in place of the frictional clamp.
La présente invention concerne un tensionneur (10) comprenant un dispositif antirecul (40) permettant une libre rotation du bras de pivot (20) dans un sens, mais pas dans l'autre. La rotation inverse est interdite par une friction capable de s'opposer au couple s'exerçant sur le bras de pivot (20) dans des conditions de fonctionnement autrement susceptibles de laisser sauter la courroie crantée. Dans les modes de réalisation de l'invention, le dispositif antirecul (40) comprend un manchon serrant (50) et un porte-pince (60) axialement interbloqués et capables de rotation l'un par rapport à l'autre. Un entourage de ressort d'embrayage (80) permet un mouvement de rotation relatif entre le manchon serrant (50) et le porte-pince (60) dans un sens mais pas dans l'autre. Une pince (70) prisonnière dans le porte-pince (60) exerce une action de friction contre l'arbre du pivot. La pince à friction peut être remplacée par un visco-coupleur.
