Free wheel device, has annular friction units fixed in respective grooves of inner casing, and integrated with groove of inner ring in contact with cams, such that friction units enter in friction contact with ring or casing

摘要

The device (1) has multiple cams (7), and outer and inner casings (8, 9) for maintenance of the cams. Annular friction units (18, 19) are fixed in respective grooves (16, 17) of the casing (9) and are integrated with a groove (5) of an inner ring (4) that is in contact with the cams, such that the friction units enter in friction contact with the ring or casing (9). The units have a rectangular transversal section.
