What Is A Freewheel Clutch? In mechanical or automotive engineering, a freewheel or overrunning clutch is a device in a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft. … In a fixed-gear bicycle, without a freewheel, the rear wheel drives the pedals around.
What is the function of a freewheel? a device in the transmission of a motor vehicle that automatically disengages the drive shaft whenever it begins to turn more rapidly than the engine. a form of rear bicycle wheel that has a device freeing it from the driving mechanism, as when the pedals are stopped in coasting.
What is freewheeling in a car? also free wheel. 1. A power-transmission device that allows the drive shaft of a motor vehicle to continue turning when its speed is greater than that of the engine shaft. 2.
