DISENGAGEABLE PULLEY DEVICE
First Claim
1. A disengageable pulley device comprising:
- a pulley mounted on an inner transmission element;
a freewheel provided with a plurality of lock-up elements mounted between a sliding track of the pulley and a sliding track of the inner transmission element, the said freewheel being intended to provide a one-way coupling between the pulley and the inner transmission element;
a cage for the lock-up elements;
at least one annular friction element provided between the cage and the sliding track of the inner transmission element to use friction to connect the cage and the said inner element, and;
at least one elastic return element positioned between at least one lock-up element and the cage, the elastic return element tending to keep the lock-up elements in contact with the sliding tracks when the freewheel is in the coupled position and in the uncoupled position.
