The driven pulley comprises a first sheave and a second sheave coaxially mounted around a main shaft. The first sheave is fixed with reference to the main shaft while the other is allowed to slide and rotate with reference to the main shaft. The driven pulley is designed so that a portion of the second sheave can enter inside the first sheave. The return spring is also provided inside the driven pulley. This driven pulley can be designed as a reversible driven pulley by adding a second set of ramps and followers. The design of the driven pulley allows it to be constructed in a very compact manner and consequently, with a smaller weight compared to an equivalent conventional driven pulley.
