Abstract: A freewheel mechanism comprising grips, mating with rolling-and-gripping rollers, that are mating with concave raceway, wherein it contains the rolling-and-rotating rollers, wherein the radius of the rolling-and-rotating roller is smaller than the radius of the rolling-and-gripping roller, wherein one or more rolling-and-rotating rollers and one or more rolling-and-gripping rollers are coaxially connected with each other, wherein each rolling-and-rotating roller is mating with one stationary interlock or rotary interlock, or rotary interlock provided with bearing, wherein each rolling-and-rotating roller is mating with one convex path, wherein the radius of the concave raceway is equal to the sum of the radius of the rolling-and-gripping roller, the radius of the rolling-and-rotating roller and the radius of the convex path. The disclosure relates also to a freewheel mechanism containing internally situated convex raceway and outside situated grips, concave paths and interlocks.
