Abstract
A decoupling pulley having a rim attached to a first power transmission element, and a torsion spring mounted in a receptacle attached to a second power transmission element, one of the power transmission elements being driving and the other of the power transmission elements being driven, the receptacle is a bell inside which is centered the spring, which spring has a first and a second end region, each of which bears on a bearing face of the bell, wherein the rim has a first drive abutment having a first face cooperating with the first end region of the spring to drive the latter in the direction of closure in a first relative rotational direction between the rim and the bell, the bell includes a first bell abutment, the angular position of which defines a first given maximum value α1 for the travel of the first end region of the spring driven to close by the first drive abutment.
