<p>The pulley has a maintaining cage (7) whose rolling elements (71) e.g. balls, are arranged between annular plates (1, 2) such that an elastically deformable device (5) i.e. stack of Belleville washers, is compressed axially by co-operation of each rolling element and an inclined zone of each one of the plates according to the relative position of a rim (4) and a hub (3) to generate axial compression force accompanied by tangential force that is a function of the angle, and transmits torque between the annular plates for transmitting the torque between the rim and the hub.</p> |
