Abstract

The freewheel device for an electric motor or engine consists of a drive tube (1) coaxial with a driven shaft. The annular space between them houses a cage (4) in which are mounted roller bearings (3). A secondary set of rollers mounted in pairs (6, 7) is mounted between the bearing rollers. When the velocity of the motor shaft is greater than the driven shaft, the secondary rollers are forced one under the other, locking the shafts together. When the relative velocity is reversed, the rollers (7) slide to the side against the spring (8) allowing the driven shaft to freewheel.
