Abstract
Free wheel, the cage (5) of which consists of two identical half cages (6, 7) each incorporating an intermediate cylindrical envelope (8) which is firmly fixed to portions forming surfaces (9, 10), which may or may not be continuous, for bearing against the surfaces of the shaft (1) and the bore (2), or the same side as, or on the side remote from the row of cams (3), the said intermediate envelope (8) incorporating notches (12 to 18) of such a shape that it allows the two half cages when positioned facing one another to be fitted together by an axial movement, enclosing the said spring between the central envelope (8) and the surface (9) for bearing upon the shaft, and leaving rectangular openings (15-17, 16, 15-17, 16) for cams (3) to be radially introduced, which thus lock axially the two half cages.
