Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.
Embodiment 1, as shown in Figs. 1-2, a kind of freewheel clutch, including be arranged successively from inside to outside clutch inner ring 1,
Clutch outer 2 and gear ring 3；The gear ring 3 includes the ring body 4 being sheathed in clutch outer 2 and is fixed on 4 one end of ring body
Internal gear 5, the internal gear 5 are engaged with driving wheel；Three are uniformly provided between the clutch outer 2 and clutch inner ring 1
One-way braking means 6, the one-way braking means 6 include wedge-like opening 6-1, roller 6-2 and spring 6-3；The wedge-like opening
6-1 is inwardly cut out by 1 outside of clutch inner ring, and the roller 6-2 is vertically placed in the wedge-like opening 6-1, roller 6-2 diameters
Less than wedge-like opening notch 6-1-1 maximum widths；The spring 6-3 is circumferentially placed between roller 6-2 and wedge-like opening 6-1.
