I need help understanding how the drive power from the chain is transferred to the wheels. I have looked at all the individual parts online, but I still do not understand it. Is there a cad file explaining it? Sorry if this is a dumb question.  |
There are a couple of different options for this.
Live axle: the axle here spins with the wheel, so you would have a keyed shaft for the axle as well as a keyed hub on the wheel. Alternatively, you could have a hex shaft and a wheel with a hex hub.
Dead axle: here, the axle isn't moving, and everything spins around it. The wheel is on a bearing, and the power is transferred to the wheel via a sprocket or pulley that is attached to the wheel.
It may help to take a look at a few cad models to better understand how WCD's work. If you have any other questions, let us know.
