Working Principle of Free Wheel

Working Principle:
    
• When hub is driven in clock wise direction, the rollers ride up on the cam 

• By wedging action they force the outer race to follow the hub 

• Then outer race with same speed as hub

• When hub speed sloes down the outer race is till moving faster than hub

• Rollers moves down to the cams and releases the outer race from hub

• This causes outer race moves independently as like roller bearing
