Abstract

Freewheel drive device that includes two concentric cylindrical sliding paths, wedging cams kept in contact with said sliding paths by means of at least one cylindrical cage and an elastic device, characterized in that the cams have two cylindrical surfaces respectively in contact with each of the sliding paths, the axes of said cylindrical surfaces of each of the cams and the common axis of the two displacement surfaces being generators of a cylinder whose diametral plane is defined by the plane that contains the axis common to the two sliding surfaces and the axis of the cylindrical surface of one of the cams in contact with the internal sliding path.
